Hace 3 días · Atomic radii may be derived from the distances between two nuclei when the two atoms are joined in a chemical bond. The radius varies with the location of an atom on the atomic chart, the type of chemical bond, the number of neighboring atoms (coordination number) and a quantum mechanical property known as spin.

Hace 4 días · Research and production took place at more than 30 sites across the US, the UK, and Canada. The project resulted in two types of atomic bombs, developed concurrently during the war: a relatively simple gun-type fission weapon and a more complex implosion-type nuclear weapon.
Hace 4 días · The first atomic bomb was detonated on July 16, 1945, in New Mexico as part of the U.S. government program called the Manhattan Project. The United States then used atomic bombs on Hiroshima and Nagasaki in Japan on August 6 and 9, respectively, killing about 210,000 people.
Hace 1 día · High-entropy alloys (HEAs) contain five or more main elements, and each element ranges in content from 5% to 35%. Due to the abundant selectivity of elements, excellent structural stability, and adjustable active centers, HEAs have been widely used in electrocatalysis. Designing HEA catalysts at the atomic scale can deeply describe their structural complexity and accurately reflect the ...
