In natural waters, the anti-correlation CO/OCS is likely to be seen in areas with high biological productivity in which reduced sulfur compounds and dissolved organic matter are abundant. This study furthers our understanding of sulfur chemistry in aqueous systems and provides another demonstration ...
Asymmetric synthesis: A metal-free novel phase-transfer-catalyzed highly regio- and enantioselective umpolung Michael reaction of α-imino esters have been achieved, which provides amino acid derivatives in high yields with up to 98 % ee. The products are successfully converted into chiral amino ...
The carbonation performance of construction and demolition waste is largely dependent on the particle size and level of humidity. Particle size and porosity are the factors which determine the contact area between the gas and solid phases. Hence, the finer and more porous a material is the more ...

Most of them are based on carboxylic acid esters with linear or branched aliphatic alcohols of moderate chain lengths (predominantly C6–C11) [3]. In relation to the classic plasticizers, the phthalate esters [6], [11], [28], adipates [29], citrates [11] besides acids esters, alkane-...
