ABSTRACT: The kinetic energy of a particle confined in a finite volume decreases with increasing volume. In the covalent bonding, the delocalization of electrons exchanged between atoms of the ...

Brian May gifted Queen fans this week by unearthing the band’s unreleased Christmas song “Not for Sale (Polar Bear).” The guitarist shared the track during the year-end episode of his Planet Rock ...

Electronegativity, a concept introduced by Linus Pauling, is a measure of an atom's ability to attract electrons in a chemical bond. It's a relative scale, with fluorine being the most electronegative ...

Thousands of proteins are known to cause disease, but while the biological activity of these proteins is understood, the way to hit and modulate them with a drug is not. Nature still has ways to bind ...

BUFFALO, N.Y. — One class of drugs that has shown promise in treating diseases ranging from lung cancer to COVID-19 are targeted covalent inhibitors (TCIs). These small molecule drugs form covalent ...

Researchers efficiently synthesize functionalized oligophenylene cages using covalent templates and cooperative intermolecular coupling. (Nanowerk News) Template-assisted synthesis dramatically ...

Template-assisted synthesis dramatically improves the yield of functionalized oligophenylene cages, report researchers from Japan. By using covalent templates to guide a six-fold Suzuki–Miyaura ...

Chemistry professor Danna Freedman crafts “designer molecules” for quantum information science. It all began with a simple origami model. As an undergrad at Harvard, Danna Freedman went to a professor ...

Takeda has returned to BridGene Biosciences for another small-molecule collaboration—this time focused on immunology as well as neurology. BridGene’s pursuit of undruggable targets is enabled by two ...

The latest short science news items from C&EN. Open an introductory chemistry textbook. What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen ...
