Scientists have discovered that reducing graphene oxide membranes with ultraviolet light alters the oxygen functional groups on the graphene oxide surface, resulting in a novel separation mechanism that is selective for charge rather than size. 

Water-based manufacturing could replace use of toxic chemicals and open the door for hybrid electronic-biological devices.

The U.S. Food and Drug Administration has released information online on microplastics and nanoplastics in foods, stating that “current scientific evidence does not demonstrate that the levels of microplastics or nanoplastics detected in foods pose a risk to human health.”

For the first time, researchers have demonstrated an approach that combines high-throughput computation and atomic-scale fabrication to engineer high-performance quantum defects in two-dimensional materials. 

Engineers have built a metasurface patterned with tunable nanoscale antennas that could be used to develop a new type of wireless communication channel.
