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.
Rice University scientists have unveiled a robust new method for arranging metal nanoparticles in geometric patterns that can act as optical processors that transform incoming light signals into output of a different color.
Positively charged gold nanoparticles are usually toxic to cells, but cancer cells somehow manage to avoid nanoparticle toxicity. Mayo Clinic researchers found out why and determined how to make the nanoparticles effective against ovarian cancer cells.
Physicists have succeeded in creating a new type of laser. Its operation principle is completely different from conventional devices, which opens up the possibility of a significantly reduced energy input requirement.
Surface nanoarchitecture provides spatially and temporally resolved stimuli response of the material, and offers defi ned control over the behavior of biomolecules and cells at the solid-liquid interface.
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.
A team of researchers at Columbia Engineering has used miniaturized electronics to measure the activity of individual ion-channel proteins with temporal resolution as fine as one microsecond, producing the fastest recordings of single ion channels ever performed.
A team of University of Pennsylvania engineers has used a pattern of nanoantennas to develop a new way of turning infrared light into mechanical action, opening the door to more sensitive infrared cameras and more compact chemical-analysis techniques.
