A team of scientists from the University of Vermont, Lawrence Livermore National Lab, the Ames Laboratory, Los Alamos National Laboratory and the University of California, Los Angeles, has made the strongest silver ever — 42 percent stronger than the previous world record. It's part of a discovery of a new mechanism at the nanoscale that can create metals stronger than any ever made before — while not losing electrical conductivity.

Electrical engineers at Duke University have devised a fully print-in-place technique for electronics that uses carbon nanotubes and silver nanowires and is gentle enough to work on delicate surfaces, including paper and human skin. The advance could enable high-adhesion, embedded electronic tattoos and bandages tricked out with patient-specific biosensors.

Researchers at Stanford University have developed nanoparticles that can be used to light up and image tumors located well below the surface of the skin. The nanoparticles should be useful for not only diagnosing and monitoring tumor progression but also for predicting how individual patients will respond to a given immunotherapy.

Earlier this year, scientists at the Massachusetts Institute of Technology published research that showed that graphene could become a superconductor if one piece of graphene were laid on top of another piece and the layers twisted to a specific angle—what they termed "the magic angle." That magic angle, scientists thought, was between 1 degree and 1.2 degrees. Now scientists at The Ohio State University, in collaboration with scientists around the world, have found that graphene layers still superconducted at a smaller angle, around 0.9 degrees.

Chemists at the University of California, Riverside, have fabricated, for the first time, plasmonic color-switchable films of silver nanoparticles. Until now, such color change of nanoparticles was mainly achieved in liquids, limiting their potential for practical applications, which include product authentication, color displays, signage, sensors, and information encryption.
