A frustrated Lewis pair accessory functionality is positioned in the secondary coordination sphere of a terpyridine ligand (Tpy(BN) = 6-morpholino-2,2':6',2-terpyridine-6-boronic acid pinacol ester) to promote directed Lewis acid/base interactions. Following metalation with VCl3, the utility of...
acid–base equilibrium, liquid-gas transfer, metals dissolution/precipitation, inhibition/limitation due to the process conditions were originally included in the presented work. The mathematical model was calibrated based on experimental data achieved with ad-hoc lab-scale tests. Cumulative hydrogen produc...

The performances of rechargeable batteries are strongly affected by the operating environmental temperature. In particular, low temperatures (e.g., ≤0 °C) are detrimental to efficient cell cycling. To circumvent this issue, we propose a few-layer Bi
There is more than one definition of a base metal: A base metal is anymetalother than thenoble metalsorprecious metals(gold, silver, platinum, etc.). Base metals typically tarnish or corrode readily. Such a metal will react with dilute hydrochloric acid to produce hydrogen gas. (Note: altho...
