This crystal impurity is sheer perfection
By Theresa Duque, Berkeley Lab Crystallization is one of the most fundamental processes found in nature – and it’s what gives minerals, gems, metals and even proteins their structure. In the past couple of decades, scientists have tried to uncover how natural crystals self-assemble and grow – and their pioneering work has led to some…
Squeeze the shock out: What different phases of piezoelectric materials tell us
In a new study, researchers from the Gwangju Institute of Science and Technology (GIST) in Korea investigated the transformation dynamics induced by an electric field in mixed-phase lanthanum-doped bismuth ferrite (BLFO) epitaxial thin films. They observed a connection between the presence of S/Stilt phases in BLFO film and their high piezoelectricity. These findings can help…
Bacteria-sized robots take on microplastics and win by breaking them down
From ACS Applied Materials & Interfaces Small pieces of plastic are everywhere, stretching from urban environments to pristine wilderness. Left to their own devices, it can take hundreds of years for them to degrade completely. Catalysts activated by sunlight could speed up the process but getting these compounds to interact with microplastics is difficult. In…
The biodegradable battery
by Empa, Swiss Federal Laboratories for Materials Science and Technology The fabrication device for the battery revolution looks quite inconspicuous: It is a modified, commercially available 3D printer, located in a room in the Empa laboratory building. But the real innovation lies within the recipe for the gelatinous inks this printer can dispense onto a…

Physicists find a novel way to switch antiferromagnetism on and off
By Jennifer Chu | MIT News Office When you save an image to your smartphone, those data are written onto tiny transistors that are electrically switched on or off in a pattern of “bits” to represent and encode that image. Most transistors today are made from silicon, an element that scientists have managed to switch…
Synthetic gelatin-like material mimics lobster underbelly’s stretch and strength
By Jennifer Chu, MIT News Office A lobster’s underbelly is lined with a thin, translucent membrane that is both stretchy and surprisingly tough. This marine under-armor, as MIT engineers reported in 2019, is made from the toughest known hydrogel in nature, which also happens to be highly flexible. This combination of strength and stretch helps…
To design truly compostable plastic, scientists take cues from nature
By Theresa Duque Despite our efforts to sort and recycle, less than 9% of plastic gets recycled in the U.S., and most ends up in landfill or the environment. Biodegradable plastic bags and containers could help, but if they’re not properly sorted, they can contaminate otherwise recyclable #1 and #2 plastics. What’s worse, most biodegradable…
Plasma treatment is today’s modern form of alchemy, increasing the value of plastic parts
