For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule ... of proteins or nucleic acids and, for example, also ensure that water has a ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...

There is a reason why ice floats on water, and it is called the hydrogen bond. Whatever that is. A hydrogen bond, in this picture, is what forms when a hydrogen atom that is already stably bound ...

Hydrogen is one of the most common elements in the world — making up 75 percent of all visible matter and more than 90 percent of all the atoms in the universe. At the same time, hydrogen bonds ...
