Millimetre-sized single crystals of covalent organic frameworks have been constructed by taking advantage of a reversible dimerization reaction of nitroso groups. Scientists and non-scientists alike ...

Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries ...

There are three types of bonds in chemistry: ionic, covalent, and metallic bonds. In this article, we will look at the differences between ionic and covalent bonds. Chemical bonding is the force of ...

Prior to 2000, many drugs that formed a covalent bond with targets did so non-selectively, which often led to undesired side effects when compared to non-covalent drugs. This led to the belief that ...

Each atom then has a complete outer shell of electrons. The slideshow shows how a covalent bond forms between a hydrogen atom and a chlorine atom, making hydrogen chloride. A simple molecule contains ...

Silica has a giant covalent structure containing silicon atoms (grey) and oxygen atoms (red) Learn more on properties of giant covalent compounds in this podcast. Listen to the full series on BBC ...

When most small-molecule drugs meet a protein target, they nestle close to their intended. But the flirtatious relationship between drug and target is often fleeting, with the drug repeatedly drifting ...
