Development of Antifreezing High‐Efficiency Dust Suppressant for Railway Coal Transportation

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the process of railway coal transportation, a large amount of coal dust is dispersed, causing serious economic loss and environmental pollution. In order to improve the low‐temperature dust suppression performance, the present study has developed an antifreeze‐type, high‐efficiency railway coal transportation dust suppressant (hereinafter ...

Hydrogen Bonding is Key Factor in Reversible NH3 Uptake Causing Vapochromic and Magnetochemical Switching in Ni(II) Paddlewheel Complexes

ChemistryEurope, EarlyView.
Nickel complexes showing reversible vapochromic and spin crossover behaviors upon coordination and release of NH3 were synthesized. They bear bidentate pyridazine ligands, which allows for formation of hydrogen bonds between NH3 and the ligand in the second coordination sphere.
