    To date, existing methods for graphene functionalization entail complex procedures, hence efficient and facile methods are desired. In this study, alkylamine functionalization on reduced graphene hydrogel (rGH) was achieved via a facile two-step method involving hydrothermal treatment of graphene oxide (GO) to rGH followed by the immersion/agitation treatment of the rGH in octylamine (OA), decylamine (DA) and dodecylamine (DDA). It was found that the interactions of the alkylamine occurred via the epoxy ring-opening and amidation. To emphasize the advantage of this method, the adsorption kinetics on methylene blue (MB) and bisphenol-A (BPA) was further accessed. Shorter alkyl chain alkylamine (OA & DA) functionalized rGHs showed improvement in their adsorption capacity due to the increase in the specific surface area of the hydrogels. The highest specific surface area was obtained for rGH-DA at 47.80 m2/g followed by rGH-OA (47.37 m2/g), rGH-DDA (42.00 m2/g) and rGH (27.29 m2/g). However, longer chain alkyl chain alkylamine (DDA) functionalized rGHs showed lower adsorption capacity posited from the crowding of long alkyl chain which decreases the π–π interactions between the MB/BPA and the graphene sheets. rGH-DA exhibited the highest adsorption capacity for MB and BPA at 482 and 228 mg/g, respectively. In addition, the alkylamine functionalized hydrogels showed high regeneration behaviour after three cycles of adsorption-desorption: above 85% and 75% for MB and BPA, respectively. This proposed facile functionalization route will open interesting possibilities in the design of novel reduced graphene-based based hydrogels with improved adsorption performance that can bring ample benefits in wastewater remediation.

    Herein, we prepared and characterized two antimicrobial cyclic peptides immobilized on reduced graphene oxide (rGO) and accessed their anti-bacterial towards Gram-negative (Pseudomonas aeruginosa) and Gram-positive (Staphylococcus aureus) bacterias. The covalent interaction between the tyrosine and histidine based cyclic peptides and the rGO occurred via the carboxylic groups of the reduced graphene and the amino side chain groups of the cyclic peptides. A selective antibacterial effect is observed for the cyclic peptides functionalized rGO. The inhibition zone test showed that both the tyrosine and histidine cyclic based peptide immobilized on rGO exhibited higher anti-bacterial potency towards the bacteria in comparison to bare rGO which can be attributed to the synergistic effect of the antimicrobial peptide and rGO.

    Mechanochemical reaction, a green synthetic esterification route was utilized to prepare long-chain cellulose esters from microcrystalline cellulose. The influence of reaction conditions such as reaction temperature and time were elucidated. Only low dosage of oleic acid, 1-butyl-3-metylimidazolium acetate, and p-toluenesulfonyl chloride were required. The success of modification reaction was confirmed by Fourier transforms infrared spectroscopy as a new absorbance peak at 1731 cm−1 was observed, which indicated the formation of carbonyl group (C=O). Solid-state nuclear magnetic resonance was also performed to determine the structural property and degree of substitution (DS) of the cellulose oleate. Based on the results, increasing reaction temperature and reaction time promoted the esterification reaction and DS. DS values of cellulose oleates slightly decreased after 12 h reaction time. Besides, X-ray diffraction analysis showed the broadening of the diffraction peaks and thermal stability decreased after esterification. Hence, the findings suggested that grafting of oleic acid’s aliphatic chain onto the cellulose backbone lowered the crystallinity and thermal stability.

    Cellulose films regenerated from aqueous alkali–urea solution possess different properties depending on coagulation conditions. However, the correlation between coagulant species and properties of regenerated cellulose (RC) films has not been clarified yet. In this study, RC films were prepared from cellulose nanofiber (CNF) and microcrystalline cellulose (MCC) under several coagulation conditions. Cellulose dissolved in aqueous LiOH–urea solution was regenerated using various solvents at ambient temperature to investigate the effects of their dielectric constant on the properties of RC film. The crystal structure, mechanical properties, and surface morphology of prepared RC films were analyzed using X-ray diffraction (XRD), tensile tester, and atomic probe microscopy (AFM), respectively. It is revealed that the preferential orientation of (110) and (020) crystal planes, which are formed by inter-and intramolecular hydrogen bonding in cellulose crystal regions, changed depending on coagulant species. Furthermore, we found out that tensile strength, elongation at break, and crystal structure properties of RC films strongly correlate to the dielectric constant of solvents used for the coagulation process. This work, therefore, would be able to provide an indicator to control the mechanical performance of RC film depending on its application and to develop detailed researches on controlling the crystal structure of cellulose.

    Rutin (RT) also known as vitamin P, is an electroactive flavanoid mainly found in plants. It is generally applied as a clinical drug, Chinese traditional medicine and consumed as a supplement and act as a healthy collagen. Consumption of RT as supplement associated with some side effects and certain people has allergy towards RT. Therefore, it is meaningful to develop a fast, simple and reliable method to detect RT to avoid health risks. This paper describes the facile synthesis of Co-MOF using 1,4-benzenedicarboxylic acid (BDC) and biphenyl-4,4-dicarboxylic acid (BPDC) as ligands through solvothermal method. The XRD patterns and FT-IR spectra confirm the formation of Co-BDC and Co-BPDC MOFs. Moreover, the SEM images revealed that the Co-BDC MOF possesses a stacked layer of MOF while Co-BPDC MOF shows a flower-like MOF. The Co-BDC and Co-BPDC MOFs were fabricated on GC electrode for the sensitive determination of RT. The ligands with different chain lengths in the MOFs have influenced the interaction of RT with the MOF. The Co-BPDC-MOF/GCE exhibited an excellent electrocatalytic activity than the Co-BDC-MOF/GCE and the fabricated electrode was successfully utilized for the determination of RT in pharmaceutical samples. The fabricated sensor exhibited the limit of detection of 0.03 µM (S/N = 3) and the superior sensitivity of 781.43 µA/mM/cm2 in the linear range detection of 0.5 – 1000 µM RT with excellent repeatability, reproducibility, and good anti-interference ability.

    To date, studies pertaining the usage of aliphatic dicarboxylic acids (DCAs) in the preparation of graphene-based hydrogels are limited and mainly has been applied either as a reducing agent or cross-linkers. The modification of the hydrogels' properties can be achieved via the introduction of small amount of additive into the starting material, graphene oxide (GO). The facile synthetic protocol enables the impartation of desired properties to the graphene-based hydrogel as intended for their specific applications. In this study, the in-situ preparation of reduced graphene hydrogel (rGH) was carried out in the presence of a series of aliphatic DCAs namely oxalic acid (OA), malonic acid (MA), succinic acid (SA), glutaric acid (GA) and adipic acid (AA) in the GO reaction mixture via green hydrothermal method and freeze-drying. The as-prepared hydrogels were systematically characterized to probe the changes in their chemical and physical changes. Higher specific surface (SSA) of the hydrogel is obtained for shorter chain length DCAs. The FTIR and XPS results also indicated that shorter chain DCAs exhibited better reducing capability in the removal of oxygen functional groups. The C/O ratio obtained showed decrement with the increase in the chain length of the DCA. On the other hand, good dispersity was found for longer chain DCAs in polar solvent. Overall, this study should provide a comprehensive understanding on hydrothermally reduced graphene hydrogels prepared in the presence of dicarboxylic acids.

    In this article, we have investigated the role of polymer regio-regularity and film fabrication technique in reducing metal diffusion from top electrodes in sandwich type devices. Poly(3-hexyl thiophene)(P3HT) polymer of varying regio-regularity was chosen for investigation and its corresponding thin films were fabricated by spin-coating(SC) and floating film transfer method(FTM). Sandwich devices with a top interface between gold and i) FTM coated regio-regular (rr) P3HT, ii) FTM coated non-regiocontrolled (nr) P3HT, iii) SC nr-P3HT and iv) SC rr-P3HT were fabricated. The current density vs voltage (J-V) characteristics of the devices revealed non-ohmic characteristics. Estimation of interfacial hole barrier heights using Fowler Nordheim tunneling model revealed a small barrier of 1.12 eV for the isotropic spin-coated nr-P3HT film which increased to 1.37 eV with an increase in film anisotropy for the FTM nr-P3HT film. The barrier height also gradually declined from 1.37 eV to 1.05 eV with increase in regioregularity from FTM nr-P3HT to FTM rr-P3HT. These observations were confirmed through optical and structural characterizations along with depth profiling of metal diffusion using XPS. Pronounced Au diffusion to a higher depth was observed in the XPS results for the highly anisotropic FTM film that decreased subsequently with decrease in anisotropy from FTM to spin-coated film. It was thus deduced that a judicious selection of fabrication technique and polymer aids in reducing metal diffusion leading to improved device performance. The results hold crucial significance towards the fabrication of efficient organic photodetectors that have a sandwich type device architecture.

    Nanofibrillated cellulose (NFC) can be used for reinforcer to silicone polymer to expect enhancement of its mechanical strength. However, NFC is a hydrophilic material, which typically poor-dispersed characteristic in non-polar polymer matrices. To overcome this bothersome characteristic, surface modification of NFC has been studied to tailor the interfacial interactions between NFC and matrices for fiber dispersibility in matrices. In this work, NFC was treated with some acids to modify a functional group in NFC. The acid treatment approaches successfully introduced the functional groups onto NFC surface, which confirmed by FT-IR, TGA, and SEM-EDS analyses. Moreover, the XRD analysis revealed that this treated NFC was the cellulose type I and acid treatments did not vary it. The TGA results showed lower thermal degradation of all treated NFC as compared to control NFC. Additionally, the effects of treated NFC as nanofiller in the silicone elastomer were evaluated the mechanical properties. The treated NFC also showed a good dispersibility in silicone composite, and no agglomeration was observed. Moreover, the tensile strength and elongation of silicone composite with treated NFC as nanofiller showed high performance compare to silicone composite with pristine NFC. The highest tensile value was recorded at 3.4 MPa in silicone/NFC-P samples using phosphoric acid-treated NFC. Therefore, a low concentration of acid treatments has the potential to be an effective method as a surface modification of NFC.

    In this article, we report single component thin film based organic phototransistors (OPTs) developed using the novel ribbon-floating film transfer method (ribbon-FTM). A low band-gap copolymer, poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta[2,1-b;3,4-b']dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)] (PCPDTBT) has been employed to develop the photoactive thin films of the devices. The fabricated polymer films were highly anisotropic in nature. To investigate the effect of film anisotropy on the device performance, organic field effect transistors (OFETs) were fabricated in two configurations namely, parallel and perpendicular, wherein the polymeric chains were oriented in line and orthogonal to the transistor channel direction, respectively. Notable differences in charge carrier mobility and device on-off ratios were observed among the two sets of devices. An on-off ratio of 4.1 × 103 and an average mobility of 0.001 cm2/V were observed in case of the perpendicular oriented OFETs which were increased to 105 and 0.003 cm2/V for the parallel oriented OFETs. A probe into the contact resistance at the respective metal/polymer interfaces of the devices was carried out using the modified transmission line method (MTLM). 4 times lower contact resistance was observed in the parallel OFET which was anticipated to be responsible for its superior performance. Further, the fabricated devices were illuminated with monochromatic red light (Pin = 0.4 mW/cm2) to observe their performance as phototransistors. Appreciable values of photosensitivity (2 × 104) and photoresponsivity (17.6 A/W) were obtained for the parallel OPTs which were found to be much higher than those of the previously reported thin film based OPTs employing other materials fabricated through conventional film coating techniques. The results presented in this report are of key significance towards the development of highly sensitive and cost-effective phototransistors which can be used in opto-sensing and imaging applications.

    High removal of heavy metals using plant-based bioflocculant under low concentration is required due to its low cost, abundant source, and nontoxicity for improved wastewater management and utilization in the water industry. This paper presents a treatment of synthetic wastewater using plant-based Tacca leontopetaloides biopolymer flocculant (TBPF) without modification on its structural polymer chains. It produced a high removal of heavy metals (Zn, Pb, Ni, and Cd) at a low concentration of TBPF dosage. In our previous report, TBPF was characterized and successfully reduced the turbidity, total suspended solids, and color for leachate treatment; however, its effectiveness for heavy metal removal has not been reported. The removal of these heavy metals was performed using a standard jar test procedure at different pH values of synthetic wastewater and TBPF dosages. The effects of hydroxide ion, pH, initial TBPF concentration, initial metal ion concentration, and TBPF dosage were examined using one factorial at the time (OFAT). The results show that the highest removal for Zn, Pb, Ni, and Cd metal ions were 98.4–98.5%, 79–80%, 97–98%, and 92–93%, respectively, using 120 mg/L dosage from the initial concentration of 10% TBPF at pH 10. The final concentrations for Zn, Pb, Ni, and Cd metal ions were 0.043–0.044, 0.41–0.43, 0.037–0.054, and 0.11–0.13 mg/L, respectively, which are below the Standard B discharge limit set by the Department of Environment (DOE), Malaysia. The results show that TBPF has a high potential for the removal of heavy metals, particularly Zn, Pb, Ni, and Cd, in real wastewater treatment.

    The use of biochar as an adsorbent for wastewater treatment purposes has been hindered due to its lower surface area compared to activated carbon. Current research on increasing surface functional groups on biochar surfaces to improve its adsorption performance suggests using high chemical concentration and long period of modification. This study solves these problems by focusing on improving surface functionalities of biochar via the hydrothermal functionalization process. Oil palm empty fruit bunch biochar was functionalized using autoclave with nitric acid as the functionalization agent. Functionalized biochar properties such as Brunauer–Emmett–Teller (BET) surface area and surface functional groups were analyzed and compared with untreated biochar. Fourier Transform Infrared (FTIR) spectroscopic analysis shows a significant increase in absorption by oxygen functional groups and is corroborated with energy dispersive X-ray (EDX) analysis. The process does not result in any major change in surface morphology and reduction in surface area value. Methylene blue (MB) adsorption test shows 7 times increase in adsorption performance. These results show that the simple hydrothermal functionalization process successfully functionalizes the biochar surface and improves its performance without affecting its surface area at lower concentration, and shorter time compared to previous studies. This result, with future large-scale experimentation using real-life equipment in palm oil mills, would provide a better technology that can be implemented in the industry.

    The widespread use of bisphenol A (BPA), a plastic additive, is becoming a troubling trend due to its harmful effects on the environment. To date, graphene-based materials (GBMs) have piqued interest among researchers in the detection and remediation of BPA attributed to their salient properties of having large surface area, high conductivity, high functionalities, etc. Recent progress in GBMs has provided researchers with a wide array of synthesis techniques for various applications. Unfortunately, literature pertaining GBMs lagged in providing up-to-date research in BPA detection and remediation. Often, published review articles focused on the wide array of pollutants detection and remediation without a specific focus on a single pollutant. Hence, this review intends to reduce the knowledge gap by focusing on the recent studies pertaining usage of GBMs applications as electrochemical-based sensors and remediators via adsorption and photocatalysis of BPA. In sensing applications, GBMs sensors have evolved to be among the preferred choice for the detection of BPA. Provided that ample comprehensive reviews on the usage of GBMs as adsorbents and photocatalyst for various pollutants have been previously published, we focused our discussion solely on BPA as the model pollutant by providing up-to-date information on their synthesis route and performance ability. Certainly, this review will be useful to new entrants and experienced researchers intending to employ GBMs as the material of interest for the detection and remediation of BPA.

    Alignment of polymer chains holds the key to the development of highly functional polymer-based field-effect transistors (FETs). The recently developed ribbon-floating film transfer method (ribbon-FTM) has the potential for development of polymer thin films with highly aligned chains, which are desirable for fabrication of efficient planar devices. These thin films consisting of well-aligned polymer chains exhibit high degree of optical and electronic anisotropies. Herein, ribbon-FTM-processed thin-film-based organic photosensitive transistors of poly(2,7-(9,9-dioctylfluorene)-alt-5,5-(4′,7′-di-2-thienylbenzo [c][1,2,5]thiadiazole)) (PFO-DBT) are reported. Under optimized fabrication conditions, polymer FETs based on PFO-DBT demonstrate a charge carrier mobility of 0.002 cm2 V−1 s−1 and an on–off ratio of 5 × 104 under dark conditions. The devices further demonstrate a photosensitivity of ≈104 and 103 and a high responsivity of 8.37 and 4.6 A W−1 against green and red light illuminations, respectively. The results hold promise for the development of conducting-polymer-based high-performance photosensitive organic field-effect transistors (OFETs).

    Polyurethanes (PUs) are a class of versatile engineering materials synthesized by the reaction between polyol, isocyanate, and chain extender as the hardener. Among various cellulose derivatives, cellulose acetate (CA) possessed unique features such as excellent mechanical properties, good thermal stability, tailorable surface chemistry, and can be used as hydroxyl providers to enhance the properties of PUs. Our goal is to develop a simple method to prepare PUs by using varying weight ratio of CA as the chain extender or crosslinking agent. PUs modified with varying weight percentage of CA (5 %, 10 %, and 30 %) (based on total parts per weight of poly(tetramethylene oxide) (PTMO) and isocyanate) were compared with PUs modified with 1,4-butanediol (BD), acting as the control. The morphological, chemical structural, thermal stability, and mechanical properties of the modified PU CA polymer were investigated thoroughly. The findings from this study found that modified PUs with CA possessed higher thermal stability. The PUs with 10 % of CA as chain extender was found to be the optimal percentage for the preparation of PUs with the highest tensile strength and elongation properties. However, the utilisation of higher weight percentage of CA reduced the elongation property of the modified PUs due to excessive crosslinking effect.

    Fundamental studies involving divalent ion intercalated graphene-based hydrogel are still lacking in terms of their adsorption behavior towards dye pollutants. In this study, we prepared a self-assembled Mg2+ and Ca2+ intercalated reduced graphene hydrogel (rGH) using hydrothermal treatment to evaluate the intercalation impact on the adsorption capability towards cationic dyes, methylene blue and rhodamine B. The morphological, structural, thermal, and textural properties of the divalent ion intercalated reduced graphene hydrogels were studied using Fourier transform infrared spectrometer, thermogravimetric analysis, Raman spectroscopy, scanning electron microscope-energy dispersive spectroscopy, X-ray photoelectron spectroscopy, Brunauer–Emmett– Teller surface area analysis, and X-ray diffraction. The increased adsorption capacity of the divalent ion intercalated reduced graphene-based hydrogels towards the dye molecules resulted from the increase in the specific surface area and pore volume due to the Mg2+ and Ca2+ bridging that formed spaces between the graphene sheets framework. Adsorption kinetics and the equilibrium adsorption isotherm were fitted by a pseudo-second-order alongside intraparticle diffusion kinetic models and Langmuir isotherm respectively. In addition, the divalent ion intercalated reduced graphene hydrogel showed good generation after three cycles of simultaneous adsorption.

    The major hurdle in melt-processing of ultra-high molecular weight polyethylene (UHMWPE) nanocomposite lies on the high melt viscosity of the UHMWPE, which may contribute to poor dispersion and distribution of the nanofiller. In this study, UHMWPE/cellulose nanofiber (UHMWPE/CNF) bionanocomposites were prepared by two different blending methods: (i) melt blending at 150◦C in a triple screw kneading extruder, and (ii) non-melt blending by ethanol mixing at room temperature. Results showed that melt-processing of UHMWPE without CNF (MB-UHMWPE/0) exhibited an increment in yield strength and Young’s modulus by 15% and 25%, respectively, compared to the Neat-UHMWPE. Tensile strength was however reduced by almost half. Ethanol mixed sample without CNF (EM-UHMWPE/0) on the other hand showed slight decrement in all mechanical properties tested. At 0.5% CNF inclusion, the mechanical properties of melt-blended bionanocomposites (MB-UHMWPE/0.5) were improved as compared to Neat-UHMWPE. It was also found that the yield strength, elongation at break, Young’s modulus, toughness and crystallinity of MB-UHMWPE/0.5 were higher by 28%, 61%, 47%, 45% and 11%, respectively, as compared to the ethanol mixing sample (EM-UHMWPE/0.5). Despite the reduction in tensile strength of MB-UHMWPE/0.5, the value i.e., 28.4 ± 1.0 MPa surpassed the minimum requirement of standard specification for fabricated UHMWPE in surgical implant application. Overall, melt-blending processing is more suitable for the preparation of UHMWPE/CNF bionanocomposites as exhibited by their characteristics presented herein. A better mechanical interlocking between UHMWPE and CNF at high temperature mixing with kneading was evident through FE-SEM observation, explains the higher mechanical properties of MB-UHMWPE/0.5 as compared to EM-UHMWPE/0.5.

    Incorporation of nanocellulose could improve wear resistance of ultra-high molecular weight polyethylene (UHMWPE) for an artificial joint application. Yet, the extremely high melt viscosity of the polymer may constrict the mixing, leading to fillers agglomeration and poor mechanical properties. This study optimized the processing condition ofUHMWPE/cellulose nanofiber (CNF) bionanocomposite fabrication in triple screw kneading extruder by using response surface methodology (RSM). The effect of the process parameters-temperature (150-190°C), rotational speed (30-60 rpm), and mixing time (30-45 min)-on mechanical properties of the bionanocomposites was investigated. Homogenous filler distribution, as confirmed by scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) analysis, was obtained through the optimal processing condition of 150 °C, 60 rpm, and 45 min. TheUHMWPE/CNFbionanocomposites exhibited improved mechanical properties in terms of Young's and flexural modulus by 11% and 19%, respectively, as compared to neat UHMWPE. An insignificant effect was observed when maleic anhydride-grafted-polyethylene (MAPE) was added as compatibilizer. The obtained results proved that homogenous compounding of high melt viscosity UHMWPE with CNF was feasible by optimizing the melt blending processing condition in triple screw kneading extruder, which resulted in improved stiffness, a contributing factor for wear resistance.

    In this study, three types of oil palm biomass (OPB) namely, oil palm mesocarp fiber (OPMF), oil palm empty fruit bunch (OPEFB) and oil palm frond (OPF), were studied and compared as the alternative fillers in the biocomposite reinforced polypropylene (PP). The fibers were treated using the optimal condition of superheated steam treatment obtained from previous study. The OPB/PP biocomposites at weight ratio of 30:70 were fabricated by melt blending technique and hot pressed moulding. Results showed that the tensile and flexural properties of optimized-SHS-treated OPB/PP biocomposites were improved by 9 – 30% and 9 – 12%, respectively compared to the untreated OPB/PP biocomposites. The same observation was recorded for thermal stability. Improved surface morphology as shown by the tensile fracture surface indicates better interfacial adhesion between SHS-treated OPB fibers with PP matrix during blending. Overall results showed that OPF/ PP biocomposites had better properties compared to biocomposites prepared from OPMF and OPEFB, suggesting that OPF is a better OPB fiber choice as a filler in PP reinforced biocomposite.

    Biochar produced from biomass with high nutrient content is essential for improving the quality of agricultural soils. An abundance of biomass is converted into biochar with high nutrient content, but studies on the conversion of pineapple and sago waste into biochar are still limited. This research aimed to produce biochar from pineapple leaf (PLB), sago bark (SBB), and sago pith (SPB) through the carbonization process with low temperature. The samples were carbonized using a laboratory electric oven at a low temperature of 350°C. The raw biomass and biochar produced were then subjected to elemental analysis and characterization. The mineral contents of carbonized biochar such as K, N, S, Mg, and Ca increased from those of the feedstock concentrations. For PLP, K element increased 24-fold from 2.44 ± 0.73% to 48.32 ± 9.92%, while N element increased from 6.13 ± 2.39% to 8.33 ± 5.34%. However, for both SBB and SPB, N and K nutrients increased by 2-fold. The study reveals that pineapple leaf biochar has the potentials to be used as an alternative soil amendment to elevate soil nutrient and quality.

    In this study, novel eco-friendly blends based on environmental-friendly polymers and compatibilizers, such as poly(ϵ-caprolactone) (PCL), cis-1,4-polyisoprene (PI), soybean lecithin (SOLE) and acrylated-epoxidized soybean oil (AESO), have been prepared in order to suggest a biodegradable joining tool used for plant grafting in agriculture, which will be competitive from the environment and economic points of view against conventional nonbiodegradable tools. PCL/PI blends, in which the portion of PCL was 75 and 50, were mixed with a compatibilizer by a melt-blending technique. The resulting blends were investigated by thermogravimetric analysis, differential scanning calorimetry and scanning electron microscopy and also their mechanical properties were determined. Afterwards, the blend films were buried in the soil. Remarkable level of weight loss was achieved in 6 weeks, ∼46%. The results showed that the addition of SOLE helped to improve the compatibility between PCL and PI due to its amphipathic property, and, besides, accelerated the weight loss of the films in soil, increasing microorganism growth on the film.

    Combination of mortar grinder mill (MG) and ionic liquid (IL) treatment was employed in order to fibrillate fibers from oil palm mesocarp fiber (OPMF) in one-step. The structural changes of OPMF before and after the treatment were examined by Thermogravimetric analysis (TGA), Fourier transformed infrared (FT-IR) spectra, Wide-angle X-ray diffraction (WAXD), Dynamic light scattering (DLS) and Scanning electron microscopy (SEM). Compared with the only use of 1-butyl-3-methylimidazolium tetrafluoroborate (BMIM[BF4]), combination of MG and IL helped to remove hemicellulose and lignin components partially from OPMF, and also fibrillated OPMF fibers at average particle diameter of 127 nm. Afterwards, the fibrillated fibers were utilized as reinforcement material for the purpose of enhancement of mechanical properties of poly(ɛ-caprolactone)(PCL). The addition of OPMF treated with the combined method led to a 64% increase in tensile strength in comparison with that of untreated OPMF. These results indicate that the combined method enables effective fibrillation. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44469.

    A novel perovskite structured barium titanate (BaTiO3) nanopowder was successfully synthesized at low temperature by a facile and an inexpensive microwave method. The synthesized nanosphere shaped BaTiO3 was analyzed using advanced characterization techniques such as X-ray diffraction analysis, Fourier transform infrared, Micro Raman, Scanning electron microscope with energy dispersive analysis and ultraviolet-visible diffuse reflectance spectroscopic techniques. Photocatalytic dye degradation study was carried out using newly synthesized BaTiO3 catalyst. The synthesized sphere shaped barium titanate nanopowders effectively degrade the various dyes such as Methylene Blue (MB), Malachite Green (MG) and Alizarin Red S (ARS) under UV light irradiation. The band gap energy of synthesized BaTiO3 was calculated by UV-DRS spectra using kubelka-Munk equation. The higher dye decomposition efficiency of nearly 100% was successfully achieved by BaTiO3 (BT10) nanosphere which was prepared using 10 min microwave irradiation.

    The recent rapid growth in graphene-based supercapacitors has reached the point where there is a need for solid-state devices with physical flexibility, which will be a crucial advantage in modern electronic devices. Herein, we summarize recent developments toward an all solid-state graphene-based flexible supercapacitor. The routes to produce graphene-based electrode materials, along with the typical fabrication techniques for flexible devices, are thoroughly discussed. Furthermore, the structural morphology of the electrode materials is closely related to the electrochemical performance, and the influence of the electrode components on the mechanical flexibility of the fabricated devices is examined. Lastly, a summary of the overall electrochemical properties and current development of the reported devices is presented progressively to predict the future trends toward the realization of an ultimate-performance graphene-based flexible supercapacitor.

  • Successful scaling-up of self-sustained pyrolysis of oil palm biomass under pool-type reactor 査読有り

    An appropriate technology for waste utilisation, especially for a large amount of abundant pressed-shredded oil palm empty fruit bunch (OFEFB), is important for the oil palm industry. Self-sustained pyrolysis, whereby oil palm biomass was combusted by itself to provide the heat for pyrolysis without an electrical heater, is more preferable owing to its simplicity, ease of operation and low energy requirement. In this study, biochar production under self-sustained pyrolysis of oil palm biomass in the form of oil palm empty fruit bunch was tested in a 3-t large-scale pool-type reactor. During the pyrolysis process, the biomass was loaded layer by layer when the smoke appeared on the top, to minimise the entrance of oxygen. This method had significantly increased the yield of biochar. In our previous report, we have tested on a 30-kg pilot-scale capacity under self-sustained pyrolysis and found that the higher heating value (HHV) obtained was 22.6-24.7 MJ kg-'1 with a 23.5%-'25.0% yield. In this scaled-up study, a 3-t large-scale procedure produced HHV of 22.0-24.3 MJ kg-'1 with a 30%-'34% yield based on a wet-weight basis. The maximum self-sustained pyrolysis temperature for the large-scale procedure can reach between 600 °C and 700 °C. We concluded that large-scale biochar production under self-sustained pyrolysis was successfully conducted owing to the comparable biochar produced, compared with medium-scale and other studies with an electrical heating element, making it an appropriate technology for waste utilisation, particularly for the oil palm industry.

    Formation of two- and three-dimensional micro architectures with chemical functions was verified by photo-vapor phase assisted surface polymerization (VASP) of functional monomer vapors combined with an auto-drawing system manipulated by prescribed programs. The surface modification by the photo-VASP of styrene vapor progressed rapidly, and a fine lines-pattern of photo-mask was transcribed as the corresponding polymer accumulations on poly(methyl methacrylate) (PMMA) substrate surfaces. Substrate surface modified by photo-VASP of acrylic acid showed reversible changes in hydrophilic/hydrophobic properties according to repeating external chemical stimuli. The successive auto-drawing by photo-VASP of three kinds of monomer vapors was examined under spot illumination from a fine optical fiber on an X-Y stage manipulated by a prescribed program, resulting in the production of a pre-designed functional structure by successful accumulations of corresponding polymers on the substrate surface.

    We here report the in-situ electrochemical deposition of silver nanoparticles (AgNPs) and a reduced graphene oxide (rGO) nanocomposite on the surface of an indium tin oxide (ITO) electrode. The nanocomposite modified ITO was used as a basic platform for the construction of a novel electrochemical biosensor for the detection of hydrogen peroxide (H<inf>2</inf>O<inf>2</inf>); where horseradish peroxidase (HRP) tagged antibodies acted as recognition elements for carcinoembryonic antigen (CEA). The AgNPs-rGO/ITO modified electrode remarkably outperformed a bare electrode because of its enhanced surface area and electrocatalytic activity, resulting in a notably amplified electrical signal for the detection of H<inf>2</inf>O<inf>2</inf>. Through a cyclic voltammetric (CV) technique, the detection limit of the sandwich type immunoassay configuration was found to be 214 μM, with a linear range of 25-500 μM, as compared to the non-sandwich system, which was 120 μM with the same linear range. In contrast, the current-time response of the resulting sandwich-type immunoassay configuration showed a wider linear response to H<inf>2</inf>O<inf>2</inf> in the range of 25-1450 μM, with a detection limit of 5.3 μM, while the non-sandwich system exhibited a linear range of 25-1355 μM (R<sup>2</sup> = 0.9992), with a detection limit of 10 μM. Therefore, the current-time response provided a more sensitive means of detecting H<inf>2</inf>O<inf>2.</inf> The resulting immunosensor also exhibited outstanding stability and reproducibility, as well as selectivity toward H<inf>2</inf>O<inf>2</inf> in the presence of several interferences.

    The objective of this study was to evaluate the effects of milling methods on tensile properties of polypropylene (PP) / oil palm mesocarp fibre (OPMF) biocomposites. Two types of mills were used; Wiley mill (WM) and disc mill (DM). Ground OPMF from each milling process was examined for its particle size distribution and aspect ratio by sieve and microscopic analyses, respectively. Results showed that DM-OPMF had smaller diameter fibre with uniform particle size compared to the WM-OPMF. Surface morphology study by SEM showed that DM-OPMF had rougher surface compared to WM-OPMF. Furthermore, it was found that PP/DM-OPMF biocomposite had higher tensile strength compared to PP/WM-OPMF, with almost two-fold. Thus, it is suggested that small diameter and uniform size fibre may improve stress transfer and surface contact between the fibre and polymer matrix and cause welldispersion of filler throughout the polymer resulted in better tensile strength of PP/DM-OPMF compared to PP/WM-OPMF biocomposite. Overall, it can be concluded that disc milling could serve as a simple and effective grinding method for improving the tensile properties of biocomposite.

    We report a simple method to produce a hydrophobic surface created by continual vapor-phase-assisted surface photopolymerization (photo-VASP) of 2,2,3,3,3-pentafluoropropylmethacrylate (FMA), which affords control over the chemical and physical properties of unique substrate surfaces without inducing any morphological changes. The photo-VASP approach was able to modify the surface of cellulose fiber substrates such as a typical, complicated, flexible and soft substrate while maintaining their original properties, imparting superior water repellency without compromising the original tactile nature of the material. The substrate surface was consecutively exposed to the vaporized initiator and monomer FMA under ultraviolet irradiation to start photopolymerization, resulting in selective coating of the irradiated surface with polymer chains. The cellulose fibers coated by the thin polymer layer retained their original tactile nature and demonstrated superior water repellency, with a controlled static contact angle >130°.

    Many studies have been reported concerning the influences of various chemical modification methods on the physical and chemical properties of natural fiber/plastic biocomposites. However, the main issue of biocomposites containing cellulose fibers is poor interphase affinity between the hydrophilic fiber and hydrophobic polymer matrix. The vapor-phase reaction technique has many advantages for the construction of fine-structured composites and coatings, arising covalently bonded compatibilizable components from/at solid substrate surfaces, even if small cracks and holes within the solid substrate. To obtain high-performance biocomposites, the development of modification process for natural fillers including biomass fiber with the vapor-phase technique is introduced in detail for many potential applications of suitably surface-modified biocomposites.
