Upcycling may help remedy the roughly 450 million tons of plastic discarded worldwide annually, of which only nine per cent ...

The plastic additive also helps control the molecular weight of the synthesized material ... Double bonds break and form between carbon atoms, allowing polymer subunits to swap.

Double bonds between carbon atoms are particularly significant ... This process conserves material while allowing control over the molecular weight of the synthesized material, influencing its ...

For each ligand, the following information is provided: PDB ID, molecular weight (MW), the computed sum of possible ... Second, missing hydrogen atoms were added to the system according to the most ...

Unlike chemical bonds, which involve the sharing of electrons by atoms or the effects of electrostatic forces among them, mechanical bonds involve molecules physically threading through one another.

The raw mass spectrometry data was compared with two different MA processing algorithms - one that uses the parent molecule spectrum and molecular weight (recursive) and one that does not ...
