But while polystyrene can be foamed easily, non-toxic semi-crystalline polymers, such as polypropylene (PP) and polylactic acid (PLA), only ... a measure of how much a material can expand when ...
Scientists have developed an artificial photosynthesis technology that produces precursors of biodegradable nylon from biomass-derived compounds and ammonia.
Osaka Metropolitan University scientists have synthesized biodegradable nylon precursors using biomass-derived compounds like L-alanine. The process incorporates artificial photosynthesis with solar ...
