A team of Brigham and Women's Hospital researchers have developed a way to bioprint tubular structures that better mimic native vessels and ducts in the body. The 3-D bioprinting technique allows fine-tuning of the printed tissues' properties, such as...
Scientists from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have taken the first images of carbon dioxide molecules within a molecular cage—part of a highly porous nanoparticle known as a MOF, or metal-organic framework, with...

A team of researchers led by the University of California San Diego has identified for the first time what drives the observed differences...
University of Oregon chemists have made substantial gains in enhancing the catalytic water dissociation reaction in electrochemical reactors, called bipolar membrane electrolyzers, to more efficiently rip apart water molecules into positively charged protons and negatively charged hydroxide ions.
The discovery,...
Three Chinese fir trees on a nature reserve in Southeastern China are the last of their kind. As their existence is threatened by human disturbance and climate change, researchers are hurrying to learn everything they can about the tree—which...
Platinum, a noble metal, is oxidised more quickly than expected under conditions that are technologically relevant. This has emerged from a study jointly conducted by the DESY NanoLab and the University of Vienna. Devices that contain platinum, such as...
High-energy X-ray beams and a clever experimental setup allowed researchers to watch a high-pressure, high-temperature chemical reaction to determine for the first time what controls formation of two different nanoscale crystalline structures in the metal cobalt. The technique allowed...
A new study from researchers at North Carolina State University suggests that a material consisting of a polymer compound embedded with bismuth trioxide particles holds tremendous potential for replacing conventional radiation shielding materials, such as lead.
The bismuth trioxide compound is lightweight,...
Researchers in the UK have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching.
The...
The Air Force Research Laboratory has developed liquid metal systems which autonomously change structure so that they become better conductors in response to strain.
Conductive materials change their properties as they are strained or stretched. Typically, electrical conductivity decreases and...
Known for their ability to remove methane from the environment and convert it into a usable fuel, methanotrophic bacteria have long fascinated researchers. But how, exactly, these bacteria naturally perform such a complex reaction has been a mystery.
Now an...
