DESYNature Photonics
Something IBM made with some very flat, very clean, very cold copper and a few hundred carbon monoxide molecules. Physicist: Actual pictures of atoms aren’t actually pictures at all. There are a few good rules of thumb in physics. Among the best is: light acts like you’d expect on...
In physical chemistry, this attraction between atoms and molecules is described in detail by the van der Waal's force. The noble gases are made up of very stable atoms and have a low chemical reactivity, which is why they can more easily exist in the monatomic state. These gases also ...

the first ever two-dimensional pictures of a "frequency comb," providing extra information that enhances the comb's usefulness in optical atomic clocks, secure high-bandwidth communications, real-time chemical analysis, remote sensing, and the ultimate in precision control of atoms and molecules. ...
The first really amazing form of carbon to be discovered is called buckminsterfullerene, after Buckmister Fuller the inventor and popularizer of many geodesic dome structures. Buckmisterfullerene is often referred to as "bucky balls" because it consists of molecules of 60 atoms in a graphite-like...
Liquids that contain ions — for example a salt solution, or molten salt — are also good conductors, as these mobile, electrically charged atoms and molecules allow a current to flow. In a wire or cable, the thickness and length also play a role. Resistance increases with length, as ...
Objects at the smallest scale — atoms and many molecules — are smaller than the wavelength of visible light. This means they arebelow the theoretical limitof what can be seen, even with the most powerful light microscope. So researchers experimentally determine the structures of molecules using ...
The elements are listed in the order in which they appear in the periodic table;the first elementshave the lowest atomic number, which increases through the table. Toward the end of the periodic table, there aren't any images of elements. Some are so rare only a few atoms have ever been...
