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.

For the first time, scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have shown how a powerful electron microscope can provide direct insight into the performance of any material by pinpointing specific atomic "neighborhoods." In particular, the scientists made molecular movies showing how the nanostructure of a semiconductor used in organic solar cells changed in response to a common processing additive known to enhance solar cell efficiency.

MIT engineers have shown that they can enhance the performance of drug-delivery nanoparticles by controlling a trait of chemical structures known as chirality—the "handedness" of the structure. The MIT team found that coating nanoparticles with the right-handed form of the amino acid cysteine helped the particles to avoid being destroyed by enzymes in the body. This finding could help researchers to design more effective carriers for drugs to treat cancer.

Researchers at the University of Washington have developed a method that could make reproducible manufacturing at the nanoscale possible. The team adapted a light-based technology used widely in biology—known as optical traps or optical tweezers—to build a novel nanowire heterostructure, which is a nanowire consisting of distinct sections comprised of different materials.

An international team of researchers has used nanoparticles to deliver a drug into specific compartments of nerve cells, dramatically increasing its ability to treat pain in mice and rats. The drug that the researchers encapsulated into nanoparticles is an FDA-approved drug used to prevent nausea and vomiting that had previously failed clinical trials as a pain medication.
