All wound up: A reversible molecular whirligig

Over the last few decades, researchers have built minuscule molecular machines that rotate or shuttle other molecules. However, it's difficult to determine the mechanical work and forces that these tiny contraptions produce, ...

A unique catalyst paves the way for plastic upcycling

A recently developed catalyst for breaking down plastics continues to advance plastic upcycling processes. In 2020, a team of researchers led by Ames Laboratory scientists developed the first processive inorganic catalyst ...

Scientists make plastic more degradable under UV light

Many plastics that are labeled as biodegradable are only compostable under industrial conditions, but scientists at the University of Bath have now found a way to make plastics break down using only UV light.

Enhancing the electromechanical behavior of a flexible polymer

Piezoelectric materials convert mechanical stress into electricity, or vice versa, and can be useful in sensors, actuators and many other applications. But implementing piezoelectrics in polymers—materials composed of molecular ...

Breaking down plastic into its constituent parts

A team of ETH researchers led by Athina Anastasaki have succeeded in breaking down plastic into its molecular building blocks and in recovering over 90% of them. A first step towards genuine plastic recycling. The chemical ...

New technique to view polyethylene creation

A team of researchers affiliated with multiple institutions in China and one in the Netherlands has found a new way to view the creation process of polyethylene. In their paper published in the journal Science, the group ...

Using shrimp shells to construct better composite membranes

Shrimp shells, plant extracts and recycled plastic have helped KAUST researchers to build a sustainable thin-film composite membrane that could replace conventional membranes whose environmental toll is greater.
