Polymeric membranes are widely used in separation technologies due to their low cost and easily scalable fabrication. However ...

For the first time, a research team led by Markus Koch from the Institute of Experimental Physics at Graz University of ...

The introduction of halogen atoms, particularly chlorine, into the phenyl scaffold enhances the benzocarbonyl reactivity in forming hemiacetal adducts with serine. Covalent molecules have the ...

This is exactly why a bond repair hair treatment deserves a spot ... such as chemical servicing like colour treatments, sun damage, chlorine from swimming pools and heat from styling.

This, of course, poses quite a conundrum, as many believe single-electron chemical bonds can’t exist. That’s because all of the current known covalent bonds—where atoms connect by sharing ...

A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent bond, known as a sigma bond, between two carbon atoms. This unique bond ...

This phenomenon sees the ligands oscillate at very high speeds and when they are close to the uranium they form metastable covalent bonds. The uranium–chlorine bonds shrink from 2.92Å in the solid ...

Chlorine has a stronger attraction for electrons than sodium ... Have students write a short caption under each picture to describe the process of covalent bonding and answer the first three questions ...

Why don’t they just stay separate? Begin to answer this question by using hydrogen as an example. Project the animation Covalent bond in hydrogen. Make sure students see that each hydrogen atom has 1 ...

It’s a given that no amount of chlorine exposure is good for your hair, but it doesn’t necessarily mean you have to sit poolside all summer. There are a few tricks that can help protect your ...
