Silicon-based tribovoltaic nanogenerators: Surface chemistry isotope effect on device performance and durability

Friction
Triboelectric nanogenerators (TENGs) are advanced devices designed to harness mechanical energy from various sources such as vibrations, friction, or shear and convert it into electrical energy.

What are the experimentally observable effects of vertex corrections in superconductors?

, 1998
We calculate the effects of vertex corrections, of non-constant density of states and of a (self-consistently determined) phonon self-energy for the Holstein model on a 3D cubic lattice.

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production

Advanced Functional Materials, EarlyView.
Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister

Dissecting the Mechanisms of a Class of Chemical Glycosylation Using Primary 13C Kinetic Isotope Effects

Nature Chemistry, 2012
Although arguably the most important reaction in glycoscience, chemical glycosylations are among the least well understood of organic chemical reactions, resulting in an unnecessarily high degree of empiricism and a brake on rational development in this ...

Isotope effects and the charge gap formation in the charge ordered phase of colossal magnetoresistance manganites

, 1999
Giant oxygen isotope effects observed in colossal magnetoresistance manganites are investigated by employing the combined model of the double exchange and interacting lattice polaron mechanism.
