Hollow atoms are special atoms with multiple missing electrons in their inner shells, while their outer shells are still fully or partially filled with electrons. Studying the production mechanisms, ...

A groundbreaking collaboration between Los Alamos scientists and Duke University has resurrected a nearly forgotten 1938 ...

Gas-cell in-situ transmission electron microscopy (TEM) is utilized to reveal the failure mechanism of MEMS H2 gas sensor with PdAg@ZnO nanowires as the sensing material. The morphology evolution of ...

Researchers have found clouds of cold gas embedded deep within larger, superheated gas clouds—or Fermi bubbles—at the Milky ...

Recently two new observatories — NASA's SPHEREx and the Vera C Rubin Observatory — released their first images.

Strata: Stories from Deep Time’ explores the origins of the air we breathe and untangles some of our planet’s oldest stories.

Now, most of the atoms in the universe are the two simplest kinds: hydrogen, which has one proton, zero neutrons and one electron; and helium, which has two protons, two neutrons and two electrons.

Addition of a series of phenol electron donors to solutions of humic substances (HS) enhanced substantially the initial rates of hydrogen peroxide (H2O2) photoproduction (RH2O2), with enhancement ...

The Hammett substituent parameter (σp) is fundamental to physical organic chemistry but often suffers from inconsistencies in experimental determination across diverse substituents. This study ...

We proposed a novel algorithm, which uses pipelining to reduce the simulation time for beam-electron cloud interaction. In the pipelining algorithm the processors are divided into subgroups, and ...
