Researchers at the University of Pittsburgh have revealed that, as a coating, carbon nanotubes can both repel and hold water in place, a useful property for applications such as printing, spectroscopy, water transport, or harvesting surfaces. When water is dropped on a carbon nanotube forest, the carbon nanotubes repel the water, which forms a sphere. But when the drop of water is flipped over, it does not fall to the ground but rather clings to the surface.

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a diagnostic platform technology that enables the detection of a broad range of biomarkers with high sensitivity and selectivity in complex biological fluids, using as little as a single drop of blood. After experimenting with a variety of recipes, the research team developed a simple, porous, 3-D matrix consisting of bovine serum albumin cross-linked with glutaraldehyde and supported by a network of conducting nanomaterials, such as gold nanowires or carbon nanotubes.

Chemistry researchers at Georgia State University have established a new imaging strategy that can track single molecules as they shimmy through tiny pores in the shells of silica spheres and that can monitor the chemical reaction dynamics on catalytic centers at the core. This discovery has led to the first quantitative measurements of how confinement at the nanoscale speeds up catalytic reactions. Understanding this surprising "nanoconfinement effect" could help guide the precise design of more efficient industrial catalysts that can conserve energy.

One of the most significant challenges standing in the way of widespread adoption of electric vehicles and aircraft has to do with mass, because the most current electric vehicle batteries and supercapacitors are incredibly heavy. A research team from the Texas A&M University College of Engineering has created strong and stiff supercapacitor electrodes based on dopamine-functionalized graphene and Kevlar nanofibers, which might enable energy to be stored within the structural body panels of electric vehicles and aircraft and, as a result, make them lighter.

A team led by scientists from the University of Washington and the University of Notre Dame used recent advances in electron microscopy to observe Fano interferences directly in a pair of metallic nanoparticles. Fano interference means that electrons in atoms move through two types of energy transitions, one discrete and the other continuous, which result in destructivae interference through their synchronized mixing.
