Hydrogels Under Superchaotropic Control: Polyoxometalate Stabilization and pH‐Responsive Crosslinking in Cellulose Ether Solutions

Angewandte Chemie, EarlyView.
Superchaotropic binding of Keggin polyoxometalates (POMs) to non‐ionic biopolymers like cellulose ethers (CEs) stabilizes otherwise hydrolytically unstable POMs in aqueous solution and allows conversion of pH‐nonresponsive polymers into pH‐responsive soft materials. The pH‐driven conversion from plenary to lacunary POMs switches superchaotropic binding

Atomic‐Scale Understanding of Selectivity Control in Nitrate Reduction on Cu(100) Under Acidic and Alkaline Conditions

Angewandte Chemie, EarlyView.
A combination of ab initio molecular dynamics simulations and density functional theory calculations clarifies the pH‐dependent origin of the selectivity of nitrate reduction on Cu(100). ABSTRACT We investigate the nitrate reduction reaction (NO3 RR) on the Cu(100) surface using grand‐canonical density functional theory (GC‐DFT) under constant ...
