The days of dryness, uneven skin tone, and elasticity loss are gone.

Nobel laureate Otto Hahn is credited with the discovery of nuclear fission. Fission is one of the most important discoveries of the 20th century, yet Hahn considered something else to be his best ...

One hundred years after “nuclear isomers” were first discovered, Philip Walker and Zsolt Podolyák pick five examples of these long-lived, excited nuclear states to show why they are so important in ...

Isomers of a given compound maintain the same chemical formula, but the unique arrangement of their constituent atoms can cause them to behave very differently. For example, one isomer of ...

Physicists in Israel have used a modern version of the Stern-Gerlach experiment to separate out water molecules according to the relative spin of their constituent hydrogen atoms. This ability to ...

Hydrogen is considered a key energy source that is becoming increasingly popular in today’s energy-conscious world. It must be in liquid form for both transport and use. At 298 K, molecular hydrogen ...

Isomers are compounds with the same molecular formulae but different structural formulae. They have the same number of each type of atom but may have different physical and chemical properties. This ...
