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 at moderate temperature. The significant… 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, this paper highlighted the advantages… More >
