Hydrogen bond cooperativity in water hexamers: atomic energy perspective of local stabilities.
Journal of Physical Chemistry A, 2013Atomic energies are used to describe local stability in eight low-lying water hexamers: prism, cage, boat 1, boat 2, bag, chair, book 1, and book 2. The energies are evaluated using the quantum theory of atoms in molecules (QTAIM) at MP2/aug-cc-pVTZ ...

Realizing the atomic active center for hydrogen evolution electrocatalysts.
Angewandte Chemie, 2020Hydrogen (H 2 ) evolution from water using renewable electrical energy is quite attractive. Though Pt/C exhibits the highest H 2 evolution reaction (HER) catalytic activity, the scarce supply and high cost limit its large-scale application. Atomic active

Abstract The claim that nuclear energy will not be necessary in the future depends upon the supposition that there need be no significant increase in global energy consumption. Population growth, and the demand to improve greatly the lot of the majority of the human race, make nonsense of this assumption. By the middle of the coming century the world's

Single-Atomic Cu with Multiple Oxygen Vacancies on Ceria for Electrocatalytic CO2 Reduction to CH4
ACS Catalysis, 2018The electrocatalytic reduction of CO2 into value-added chemicals such as hydrocarbons has the potential for supplying fuel energy and reducing environmental hazards, while the accurate tuning of electrocatalysts at the ultimate single-atomic level ...

Nature, 1949
IN an earlier paper1, we published the results of some calculations of analytical atomic wave functions for the ground-states of atoms lithium to neon. Since that tune, we have had several requests for the values of the associated total electronic energies.

The Atom and its Energy Meet the Atoms
Nature, 1948PROF. ANDRADE is an old hand at explaining the mysteries of atomic structure ; his "Structure of the Atom" was the standard text in the days when electrons circulated on nicely calculable orbits around the nuclei that Nature provided for our study. The electrons have long since abandoned their tramway-like orbits and, like buses in a fog, have a mere ...

Atoms and molecules emit electromagnetic radiation or photons when the electrons or nuclei undergo transitions between various energy levels of the atomic or molecular system. Detailed theory of radiation requires quantum electrodynamics to fully describe the interaction between materials and electromagnetic radiation, so it will not be detailed in ...
