Sept. 2 (UPI) --Scientists in Japan have developed a new way to measure the energy difference of an atom and a molecule. The new algorithm, described Thursday in the journal Physical Chemistry ...

OSAKA, Japan. As newly reported by the journal Physical Chemistry Chemical Physics, researchers from the Graduate School of Science at Osaka City University have developed a quantum algorithm that can ...

Chemists have calculated the structure of a very unusual molecule, one whose hyperactive atoms have earned it the nickname "the scrambler." This highly caustic "protonated methane," or CH5+, is also ...

Mass spectrometry provides rapid and quantitative identification of protein species with relatively low sample consumption. The trend towards biological analysis at increasingly smaller scales, ...

Most of the units we rely on are based on precision microscopic measurements—regular fluctuations in certain atoms define one second of time, for example. A major exception to this is the basic unit ...

For example, the atomic number of sodium is 11. Every sodium atom has 11 protons and 11 electrons. It has 11 positive charges and 11 negative charges. The mass number of an atom is its total number of ...

Physicists have discovered a unique new molecule that could lead to many useful applications, and show how chemical reactions can be studied on a microscopic scale using tools of physics. UCLA ...
