A shorter hydrogen bond, for instance, indicates stronger hydrogen bonding and a relatively weaker covalent bond. This was reflected, as expected, in lower spectroscopic frequencies for the H–F ...

Hydrogen bonding, so significant in biology, is finally being exploited as a primary adsorption mechanism. BIA Separations shows how. Its salt-tolerant approach separates proteins by size.

Researchers at the École Polytechnique Fédérale de Lausanne (EPFL) and Kyoto University have formulated a hydrogen-rich ...

Here's how bond builders actually work and their benefits. ... These structures are held together by disulfide and hydrogen bonds, which are responsible for hair's strength, elasticity, and shape.

A hydrogen bond, in this picture, is what forms when a hydrogen atom that is already stably bound into one molecule finds itself attracted to a highly electronegative atom ...

Carboxylic acids are ubiquitous in bioactive organic molecules and readily available chemical building blocks. Carboxylic ...

Hydrogen atoms bond with other hydrogen atoms to make hydrogen gas (H 2). Or they can bond with other atoms like oxygen to make water (H 2 O) or carbon to make methane (CH 4) or many other atoms. Step ...

Hydrogen bonds are found everywhere in chemistry and biology and are critical in DNA and RNA, where they bond the base pairs that encode genes and map protein structures.

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. This technique can be used ...

The hydrogen electrons eventually find their way to this section, reuniting with protons and bonding with oxygen atoms. Electricity is produced; the only by-products are pure water and heat. But, ...

Chemists have long known what a hydrogen bond should look like, but until last week, most hadn’t actually seen an image of one. Now, researchers from the Chinese Academy of Sciences have been ...

Hydrogen bonds bind water molecules to each other, giving the droplet its characteristic shape. But they're easily broken. Researchers recently discovered a form of hydrogen bond so strong it's ...
