Adjusting nitrogen levels allows manufacturers to alter a material’s properties; for example, a nitrogen-poor polymer may be more flexible, while a nitrogen-rich polymer may be more flame-resistant.

Engineer Patents Waterlike Polymer to Create High-Temperature Ceramics Date: March 30, 2017 Source: Kansas State University Summary: Using five ingredients — silicon, boron, carbon, nitrogen and ...

Polymers are materials made of long, ... (DNA and RNA) are polymers of nucleotides — complex molecules composed of nitrogen-containing bases, sugars and phosphoric acid, ...

This capability has been successfully tested on several plastics, including PMMA and polystyrene. The monomer recovery yields reach up to 62% for polystyrene—a breakthrough for this polymer ...

Unlike previous polymers with the same strength, this new material comes exclusively in membrane form. It’s also 50 times more airtight than the most impermeable plastics on the market.

The researchers made molecular chains with alternating sections of the two polymers. The long PDMS parts provide flexibility, and the urea parts provide strong bonds, creating a new polymer with both ...

Using a sulfur diimide reagent, the researchers introduced amine groups – chemical units containing nitrogen – at specific locations along the rubber’s polymer chains. These nitrogen-containing groups ...

The use of supercritical fluids (mainly nitrogen and carbon dioxide) in physical TFIM process-es, such as MuCell by Trexel today permits the manufacturer of microcellular foams with pore diameters ...
