Study provides better understanding of water's freezing behavior at nanoscale

The results of a new study led by George Washington University Professor Tianshu Li provide direct computational evidence that nucleation of ice in small droplets is strongly size-dependent, an important conclusion in understanding water's behavior at the nanoscale. The formation of ice at the nanoscale is a challenging, basic scientific research question whose answer also has important implications for climate research and other fields.

Self-assembled functionalized nanowires using multiple modified amyloid peptides

Researchers have successfully developed a new technique for efficiently creating functionalized nanowires for the first time ever. The group focused on the natural propensity of amyloid peptides, molecules which are thought to cause Alzheimer's disease, to self-assemble into nanowires in an aqueous solution and controlled this molecular property to achieve their feat.
