This study explores strategies to develop highly efficient direct carbon fuel cells(DCFCs) by com-bining a solid-oxide fuel cell(SOFC) with a catalyst-aided carbon-gasification process. This system employs Cu/CeO 2 composites as both anodic electrodes and carbon additives in a cell of the type: carbon|Cu-CeO 2/YSZ/Ag|air. The study investigates the impact on in situ carbon-gasification and DCFC performance characteristics of catalyst addition and variation in the carrier gas used(inert He versus reactive CO2). The results indicate that cell performance is significantly improved by infusing the catalyst into the carbon feedstock and by employing CO2 as the carrier gas. At 800 ℃, the maxi-mum power output is enhanced by approximately 40% and 230% for carbon/CO2 and car-bon/catalyst/CO2 systems, respectively, compared with that of the carbon/He configuration. The increase observed when employing the catalyst and CO2 as the carrier gas can be primarily at-tributed to the pronounced effect of the catalyst on carbon-gasification through the re-verse-Boudouard reaction, and the subsequent in situ electro-oxidation of CO at the anode three-phase boundary.

A research was conducted to synthesize new elastic polymers via polyesterification of glycerol (GE) with azelaic (AZ) and succinic acids (SU) as an added value to the surplus of GE from palm oil industry in Malaysia. This paper reports the successful, simple synthesis of unique elastic polyesters via the catalyst-free polyesterification of multifunctional monomers derived from GE, AZ, and SU. The ratio of the diacid to the alcohol used in this experiment was 1:1. The resulting polyesters, specifically, poly(GE/azelate/succinate), p(GAS), were characterized using nuclear magnetic resonance spectroscopy (NMR), Fourier-transform infrared spectroscopy (FTIR), gel permeation chromatography (GPC), thermal gravimetric analysis (TGA), and differential scanning calorimetry (DSC). The thermal stability increases with an increasing number of azelate units in the polyesters. The desired final product can be achieved by tuning the monomer ratio and the water removal efficiency. © 2014 The Author(s). Published by Taylor & Francis.

The present work was done in order to develop and find out suitable conversion methods for coconut husk wastes into value-added products. It is well-known that coconuts husk waste is hydrophobic therefore ethanol with different doses was used as a surfactant to enhance the removal efficiency. Treated samples at different adsorbent amounts, sintering temperatures & sintering time, stirring time, pH, and solution temperatures for color removal of Methylene Blue (MB) & Rhodamine B (RhB) and ammonium concentration were evaluated by using UV-Visible Spectroscopy. At 300°C, results showed complete removal for MB and more than 75% for RhB, whereas removal of ammonium ion reached around 52% when sintering product from husk waste was used. Further investigation was carried out for ammonium ion to understand the desorption kinetic behaviors and isotherm models. Kinetics indicated that desorption of ammonium ion followed pseudo-first order equation. Adsorption thermodynamic parameters such as ΔG, ΔH, and ΔS followed Van’t Hoff plot for adsorption and found to be negative which indicated that the adsorption process for ammonium onto coconut husk was physical, spontaneous and exothermic.

Objective: To isolate and investigate antioxidant and α-glucosidase inhibitor compounds in the leaves of Quercus gilva Blume(Q. gilva).Methods: Dry leaves of Q. gilva were extracted with methanol and the methanolic extract was further separated by silica gel column chromatography using several solvents with increasing polarity. The antioxidant activities of the isolated compounds were evaluated using various in vitro assays: 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity, hydrogen peroxide radical scavenging activity, β-carotene bleaching assay, and reducing power assay. The α-glucosidase inhibitory assay was conducted against α-glucosidase from Saccharomyces ***: Three compounds were isolated and their structures were identii ed as catechin(1), epicatechin(2), and tiliroside(3) using an instrumental analysis. Compound 2 had higher antioxidant activity with inhibitory concentrations(IC50) of(22.55 ± 2.23) μmol/L than that of quercetin, which was used as the standard, with an IC50 of(28.08 ± 2.39) μmol/L, followed by compound 1 with IC50 of(40.86 ± 3.45) μmol/L. On the other hand, compound 3 had the lowest antioxidant activity with an IC50 of(160.24 ± 8.15) μmol/L. However, compound 3 had the highest α-glucosidase inhibitory activity with an IC50 of(28.36 ± 0.11) μmol/L, followed by compounds 1 and 2 with(168.60 ± 5.15) and(920.60 ± 10.10) μmol/L, ***: The results obtained for the antioxidant activities and α-glucosidase inhibitory activities in a methanolic extract from the leaves of Q. gilva coni rmed the potential of this plant as a source of natural antioxidants and antidiabetic medicine.

AIP Conference Proceedings 2016年第1期1784卷

作者： Yasmin H. A. M. Mushrifah Idris Siti Rozaimah Syeikh Abdullah 1School of Environmental Science & Natural Resources Faculty of Science Technology Universiti Kebangsaan Malaysia Malaysia 2Head of Tasik Chini Research Center Universiti Kebangsaan Malaysia Selangor Malaysia 3Department of Chemical and Process Engineering Faculty of Engineering and Built Environment Universiti Kebangsaan Malaysia Malaysia

Water from Tasik Chini has been used to run through a series of reed bed system to test for its use as potable water. This study used aquatic plants namely Lepironia articulata and Scirpus grossus which grows wild and abundant at Tasik Chini wetland as selected macrophyte to aid in the system. This study started with batch flow and free-surface flow (FSF) for 30 days. Result indicated that, L. articulate alone gave 76 % of removal efficiency in TSS and 86% in removal of *** number of colonies on the plate. This was higher than S. grossus and combination of *** and ***. However, tank combination of S. grossus and L. articulata gave 100% efficiency in removal color, and improved ph better. In trace element removal, L. articulata was also capable of removing arsenic and lead (Pb) at 34.8% and 64.2% respectively. While, S. grossus shows best efficient at removing cadmium (Cd), and manganese (Mn), which is 46.8 % and 75.6% respectively. Combination of S. grossus and L. articulata gave best removal percentage in removing iron (Fe) which was 74.3%.

Batch investigations on phosphate removal from synthetic wastewaters using sensor steel furnace slag

引用

Sensor Letters 2014年第9期12卷 1439-1444页

作者： Yang, Wanqiu Miao, Deren Li, Ye Huang, Weiying Department of Chemical Science and Technology Kunming University Kunming China Beijing Municipal Research Institute of Environmental Protection National Urban Environment Pollution Control Engineering Techniques Research Center National Environmental Protection Industrial Sewage Pollution Control Engineering Techniques Center Beijing China

The sensor steel furnace slag (SFS) was used to remove phosphate (P) from synthetic wastewaters. Batch experiments showed an increase in the amount of P removal in the concentrations range 1-400 mg/L followed by a noticeable decrease in the concentration range 500-800 mg/L. At equilibrium pH ≥ 8.5, the P removal is dependent on the concentration of calcium ions due to the formation of the low-solubility Ca-P precipitate. On the other hand, the P removal is dominated by the adsorption process while the equilibrium pH -, SO42- and NO3- ions had no significant effects on P removal efficiencies. However, the presence of F- and HCO3- dramatically affected the P removal. The P desorption rates, extracted by Toxicity Characteristics Leaching Procedure and Synthetic Precipitation Leaching Procedure extractants, are all below 10%. This study showed that sensor SFS could be used as an efficient binding agent for the sequestration of P from wastewaters.
