Summary of "Boosting Electrocatalytic Hydrogen Evolution Activity with a NiPt3@NiS Hetero-Nanostructure Evolved from a Molecular Nickel-Platinum Precursor."

A facile synthetic route to NiPt3@NiS hetero-nanostructures is reported, starting from a subsulfido bridged heterobimetallic nickel-platinum molecular precursor. Notably, the NiPt3@NiS on nickel foam displayed merely an overpotential of 12 mV at -10 mAcm-2, which is substantially lower than Pt or NiS, synthesized through a similar approach and represents the most active hydro-gen evolution reaction (HER) electrocatalysts yet reported in alkaline solutions. NiPt3@NiS electrodes demonstrated an un-ceasing HER stability over eight days, which is well over those reported for Pt-based catalysts signifying capability of scaled hydrogen production.

Evolution at the molecular level of DNA sequences and proteins. (Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)

The techniques used to produce molecules exhibiting properties that conform to the demands of the experimenter. These techniques combine methods of generating structural changes with methods of selection. They are also used to examine proposed mechanisms of evolution under in vitro selection conditions.

Hydrogen. The first chemical element in the periodic table. It has the atomic symbol H, atomic number 1, and atomic weight 1. It exists, under normal conditions, as a colorless, odorless, tasteless, diatomic gas. Hydrogen ions are PROTONS. Besides the common H1 isotope, hydrogen exists as the stable isotope DEUTERIUM and the unstable, radioactive isotope TRITIUM.
