QLEDs â light-emitting diodes that rely on nanocrystals called quantum dots â are usually made with toxic heavy metals. A strategy has been developed to make QLEDs with a performance comparable to that of commercially available technologies but using a more environmentally friendly alloy of zinc, selenium, telluriu

A practical recycling strategy for making thiophosphate molecules with enzymes
2+ week, 3+ day ago (57+ words) An enzymatic platform for constructing the thiophosphate molecular motif without relying on large amounts of expensive reagents has been developed. The method lays the foundation for developing enzymatic cascades to synthesize thiophosphate-containing motifs in drug development. An expensive reagent to…...
