Scanning electron microscopy is a general type of electron microscopy that generates a topological image of a sample using a beam of electrons to achieve much higher spatial resolution than light ...

For thousands of years, thinkers argued about whether light is made of particles or waves. At the beginning of the 20th ...

Scientists are exploring 2D materials — sheets just one atom thick — with unique and promising electronic properties. When two of these sheets are layered at specific angles, they can exhibit ...

At first glance, it might seem obvious that atoms touch each other, especially when you consider the material world around us ...

Researchers have finally proven that atomic diffraction is possible, paving the way for a new understanding of quantum ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ...

In 1925, grad student Cecilia Payne first proposed that stars were mostly made of hydrogen and helium and shaped our ...

Physicist John Wheeler was involved in much of this Earth-shattering work, such as understanding the structure of the atom, ...

In a world seemingly defined by a conflict between science and spirituality, panpsychism offers a fresh perspective that ...

Using heavy water, the researchers could also selectively introduce deuterium atoms along with chlorine. The weightier hydrogen isotope is useful for probing reaction mechanisms, as well as studying ...
