Structural origin of glass transition

Scientists have demonstrated through computer simulations that the enhancement of fluctuations in a liquid's structure plays an important role as a liquid becomes a solid near the glass-transition point, a temperature below the melting point. This result increases our understanding of the origin of the glass transition and is expected to shed new light on the structure of liquids, thought until now to have been uniform and random.

Nanoscale asymmetry leads to Janus-like nanoparticle membranes

Using grazing incidence small angle x-ray scattering (GISAXS) and surface-enhanced Raman scattering (SERS), very small differences in the distribution of coated-nanoparticle membranes were detected and found to be responsible for their folding into tubular structures. Molecular dynamics simulations show this is related to surface molecular packing density and mobility.

A new way to image surfaces on the nanoscale

A multi-institutional team of scientists has taken an important step in understanding where atoms are located on the surfaces of rough materials, information that could be very useful in diverse commercial applications, such as developing green energy and understanding how materials rust.

U.S. government calls for nanotechnology-inspired Grand Challenges

Today, the Office of Science and Technology Policy issued a Request for Information (RFI) seeking suggestions for Nanotechnology-Inspired Grand Challenges for the Next Decade. A Grand Challenge is an ambitious but achievable goal that requires advances in science and technology to achieve, and that has the potential to capture the public?s imagination.

Hot nanostructures cool faster when they are physically close together

A complete description of nanoscale thermal transport is a fundamental problem that has defied understanding for decades. Here, researchers uncover a new regime of thermal transport near nanoscale structures, where counterintuitively, nanoscale hot spots cool more quickly when placed close together than when they are widely separated.

3D bioprinter uses carbon nanotube enhanced cellulose

Researchers have managed to print and dry three-dimensional objects made entirely by cellulose for the first time with the help of a 3D-bioprinter. They also added carbon nanotubes to create electrically conductive material.
