“Molecular Scissors” for Plastic Waste

12/04/2019

A research team from the University of Greifswald and the Helmholtz-Zentrum Berlin (HZB) has solved the molecular structure of an important enzyme (MHETase) at the synchrotron radiation source BESSY II. MHETase was discovered in bacteria and, together with a second enzyme – PETase –, is able to break down the widely used plastic PET into its basic building blocks.

World's fastest hydrogen sensor could pave the way for clean hydrogen energy

12/04/2019

Hydrogen is a clean and renewable energy carrier that can power vehicles, with water as the only emission. Unfortunately, hydrogen gas is highly flammable when mixed with air, so very efficient and effective sensors are needed. Now, researchers from Sweden present the first hydrogen sensors ever to meet the future performance targets for use in hydrogen powered vehicles.

Synthetic rubber outperforms natural rubber

09/04/2019

Natural rubber from rubber trees is a raw material with a limited supply. Synthetically produced rubber, on the other hand, has not yet been able to match the abrasion behavior of the natural product, rendering it unsuitable for truck tires. But now, for the first time, a new type of synthetic rubber has been developed that achieves 30 to 50 percent less abrasion than natural rubber.
