What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen bond? A hydrogen bond is an electrostatic attraction between an atom and the positive ...

Using a technique called high-resolution atomic force microscopy (AFM), researchers in China have visualized the molecular structure of a hydrogen bond. Image: AFM images of 8-hydroxyquinoline on ...

Nobel Laureate Linus Pauling, Ph.D., predicted in 1939 that hydrogen bonding would prove to be more significant in the field of biology than any other type of chemical bond. His prediction has ...

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 ...

A hydrogen bond 1 forms between an electronegative atom (the acceptor) and a hydrogen atom covalently bound to another electronegative atom (the donor). Hydrogen bonds are of key importance in ...

A metal hydride is formed when hydrogen bonds with a metal, and they are sometimes referred to as solid-state hydrogen batteries. The very first metal hydrides date back to the 1930s. However ...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. For the first time, scientists have succeeded in ...

iStock "We found that by using high-frequency sound waves the hydrogen bond lattice can be disrupted—we call this 'frustration.' This 'frustration' process essentially weakens the water bonds ...

IT has been recognized for many years that under certain conditions a hydrogen atom can form a connecting link between two other atoms. It may be considered as forming a bond between them ...

Hydrogen bonds are at the very core of life as we know it, and now for the first time ever scientists have managed to visualize these transient molecular associations. A team of researchers from ...
