Abstract This study focuses on optimizing practical synthesis to produce ultrafine CdS nanoparticles. Three separate chemical synthesis processes, namely microwave, wetchemical, and sonication methods, are used to generate CdS nanoparticles. Moringa oleifera leaf extract employed green syntheses of CdS nanoparticles are also performed for additional discussions. The generated CdS nanoparticles were subjected to a comparative assessment to identify the most effective processing method for synthesizing CdS nanoparticles. Even though the processing parameters were altered over their synthesis, the hexagonal structure was retained in the CdS nanoparticles. The observed results of CdS nanoparticles from XRD, SEM/EDX, and More >

Abstract In this work, we have successfully cross-linked the different weight ratio of Chitosan-PVA blend with sulfuric acid. The effect of cross-linker on the properties of blends are studied by using different experimental technique. The cross-linked membrane provides higher ion exchange capacity due to the procurement of extra ionic hooping sites in the membrane. The compatibility of the blends are confirmed from the FTIR and DSC analysis. The crosslinking reaction fastening the phase transition behavior of the blends which reduces the glass transition temperature. The highly compatiblized cross-linked blend provides higher tensile strength and lower modulus… More >

Abstract Biochar, one of the products of thermochemical conversion of biomass, possesses specific physiochemical properties such as conductivity, pore adsorption, surface functional groups, and cation exchange capacity. Anaerobic digestion (AD) as a classical bio-wastes conversion technology, suffers from inhibitions, process instability, and methanogenic inefficiency which limit its effi- ciency. With the advantages of pH buffering, functional microbes enrichment, inhibitors alleviating, and direct interspecies electron transfer (DIET) accelerating, biochar suggests a promising application as additives for AD. Herein, this paper reviewed the noting physicochemical properties of biochar, and discussed its roles and related mechanisms in AD. Further, More >
