Economical PEF Production

Efficient titanium-based catalyst used to produce PEF, the biobased alternative to PET

30-Aug-2022

One possible replacement for drink containers made from PET is polyethylene furandicarboxylate (PEF), made from renewable resources. However, the production of the raw material for PEF from biomass is still rather inefficient. A new titanium-based photocatalyst could be about to change this, ...

Firefly Luminescence Reveals Pesticides

Luciferin synthesis and organophosphate detection by a luminescent enzymatic cascade

16-Mar-2022

A luminescence reaction modeled on fireflies can detect contamination with organophosphates with high sensitivity, ease, and low cost. At the center of this technology is a new enzymatic method for the synthesis of analogues of luciferin, the substance that makes fireflies glow. As reported by a ...
