Anomalously large kinetic isotope effect

Open Chemistry, 2007
AbstractActivated diffusion of water between macromolecules in swollen cellulose is accompanied by anomalously high kinetic isotope effects of oxygen. The separation factor of heavy-oxygen water (H218O /H216O) is thousands of permilles instead of tens of permilles according to modern Absolute Rate Theory.

Atomically Dispersed Sn on Core‐Shell MoS2 Nanoreactors as Mott‐Schottky Phase Junctions for Efficient Electrocatalytic Hydrogen Evolution

Advanced Materials, EarlyView.
A hollow core‐shell structured Mott‐Schottky phase junction 2H@1T‐MoS2‐Sn1 nanoreactor with a definite Sn‐S2‐Mo motif is designed, which exhibits a record overpotential of 9 mV at 10 mA cm−2. The 2H@1T‐MoS2 Mott‐Schottky phase junction promotes charge transfer, while the surface Sn single atom facilitates the reduction of adsorbed H⁺, thus accelerating
