Treatment of wastewater using bioadsorbent has gained interest as one of the tertiary treatment methods. Bioadsorbents from peat, coconut shell, fruit stones and oil palm biomass have been produced but the bioadsorbent ability in removing pollutants from biologically treated palm oil mill effluent final discharge is scarcely reported. This research attempts to treat biologically treated palm oil mill effluent final discharge using steam activated oil palm mesocarp fiber bioadsorbent without the use of chemicals as activating agents. Oil palm mesocarp fiber was carbonised at 600 °C for 30 min and later activated using steam at same temperature for another 30 min. The Brunauer-Emmett-Teller (BET) surface area of the bioadsorbent was found to be 494 m2/g. Bioadsorbent produced was then used to treat biologically treated palm oil mill final discharge by mixing both bioadsorbent and the wastewater into a conical flask and shaken at 150 rpm for 24 h. At 10 g/L dosage, the bioadsorbent reduced the chemical oxygen demand and suspended solid of biologically treated palm oil mill effluent final discharge from 395 mg/L and 117 mg/L down to 303 mg/L and 14 mg/L, respectively. Consecutive treatments at 10 g/L dosage resulted in higher removal of the chemical oxygen demand and suspended solids up to 122 mg/L and 7 mg/L, respectively, which meets the river water quality, making the final wastewater suitable as recycled water for the zero-emission system in the palm oil mill.

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.

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.

記述言語：英語掲載種別：研究論文（学術雑誌）

Nanosized Zn-WO3 and ZnWO4 materials have been prepared by microwave irradiation method. The physico-chemical characterization of the prepared nanomaterials was carried out by X-ray diffraction (XRD) and high resolution-scanning electron microscopy (HR-SEM) techniques. The size and shape of the ZnWO4 material can be controlled by changing the temperature. The XRD analysis revealed the formation of monoclinic phase of the calcined nanopowder. The HR-SEM images showed the sphere and plate shape particles. The electrochemical behavior of the ZnWO4 modified electrodes was investigated using electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) techniques. The synthesized material shows the pseudocapacitance. The specific capacitance of 35.70 F/g was achieved for the Zn-WO3 nanopowder.

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.

Cu-WO3 and CuWO4 nanopowders have been successfully synthesized by simple microwave irradiation method. The prepared nanopowders were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy techniques. The XRD pattern revealed the formation of orthorhombic and anorthic phase for the as-synthesized and heat-treated samples, respectively. The formation of nanoporous structure was confirmed by SEM for both as-prepared and heat-treated samples. The electrochemical performance of the Cu-WO3 and CuWO4 modified electrodes was investigated using electrochemical impedance spectroscopy, cyclic voltammetry and galvanostatic charge–discharge techniques. The specific capacitance of 15.08 F/g was achieved for the Cu-WO3 nanopowder.

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.
