Twisted materials—known as moiré structures—have revolutionized modern physics, emerging as today's "alchemy" by creating ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic ...

Explain to students that the two electrons in the bond between the hydrogen atom and the oxygen atom can be thought of as “belonging” to each atom. This gives each hydrogen atom two electrons in its ...

The lowest energy shell, which is closest to the nucleus, is called the K-shell and can only fit two electrons. Once the K-shell is filled, any subsequent electrons go first into the L-shell, ...

Exciton fission: One photon in, two electrons out Date: May 5, 2023 Source: Fritz Haber Institute of the Max Planck Society Summary: Photovoltaics, the conversion of light to electricity, is a key ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

Just two strategies existed at the time to categorize these elements: separating them into metals and nonmetals or grouping them by an element's number of valence electrons (the electrons in the ...

Electrons play many roles in solid materials. When they are weakly bound and able to travel—i.e., mobile—they can enable ...

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial in 2D semiconductors, according to new findings by UC Santa Barbara ...

Note: When two materials are rubbed together in a static electricity activity, one material tends to lose electrons while the other material tends to gain electron. In this activity, human skin tends ...
