Nuclear Magnetic Resonance (NMR) spectroscopy has long been an indispensable tool for the characterisation of molecular structures and dynamics, offering rich insights into chemical environments, ...

A macromolecule is a very large molecule of high molecular weight and is made up of smaller subunits known as monomers. The majority of common macromolecules include synthetic and natural polymers, ...

Molecular weight is a main feature employed when characterizing polymer-based products. The term describes the molar mass distribution of polymer chains which can significantly vary within polymers of ...

Polyurethane is a common polymer which can sometimes be challenging to analyze. Polyurethanes are utilized particularly in rigid and flexible foams, elastomers and resins. Their performance ...

Proteins are made up of amino acid residues which are bound together by peptide bonds between the amino nitrogen (N) and the carboxyl group. Just 21 distinct amino acids exist, but they can bind ...
