In this study, quaternized chitosan microspheres (QCMS) were prepared and their adsorption performance of Acid Red 18 from aqueous solution was studied. Equilibrium was attained within 120 minutes and maximum removal of 94.06% was achieved. Langmuir and Freundlich isotherm models have been investigated. The maximum capacity obtained from the Langmu...

Anode slime is an extremely valuable secondary resource for the recovery of silver and has attracted wide attentions. Effective metal recovery is usually constrained by either environmental hazards or high consumption of lixiviant for cyanide and non-cyanide leaching reagents. To tackle these issues in the process of silver recovery from anode slim...

As important rare raw material, Se and its compounds are widely used in metallurgy, glass manufacturing, chemicals and pigments, and electronics industry. However, current processes used for Se recovery are usually constrained by the serious pollution and high energy consumption. To dispose the issues in the process of Se recovery, this study devel...

Resistance to metals and antimicrobials is a natural phenomenon that existed long before humans started to use these products for veterinary and human medicine. Bacteria carry diverse metal resistance genes, often harboured alongside antimicrobial resistance genes on plasmids or other mobile genetic elements. In this review we summarize the current...
A new monoterpenoid based fluorescent receptor (E)-2-(5-allyl-2-hydroxy-3-methoxybenzylidene)-N-phenylhydrazinecarbothioamide (1) was synthesized and applied as a fluorescent chemosensor for the selective detection of bioactive Zn2+ and Mg2+ ions over other tested cations and anions. The selective complexation with the receptor 1 provides a fluores...
A strain of 10% is applied to 316L stainless steel specimens at strain rates of 7.7 x 10(4) s(-1), 200 s(-1) and 50 s(-1) using vaporizing foil actuator (VFA) technique for the highest strain rate and dynamic plastic deformation (DPD) for the lower strain rates. There is a dramatic increase in hardness with increasing strain rate, rising to over 2....
