Most attempts to turn textiles into wearable technology use stiff metallic fibers that alter the texture and physical behavior of the fabric. And coating methods that are successfully able to apply enough material to a textile substrate to make it highly conductive also tend to make the yarns and fabrics too brittle to withstand normal wear and tear. Now researchers at Drexel University have shown that they can create a highly conductive, durable yarn by coating standard cellulose-based yarns with a type of conductive two-dimensional material called MXene.

Bionanomotors, like myosins that move along actin networks in cells, are responsible for motion in all life forms. So the development of artificial nanomotors could make robots more effective and versatile teammates for soldiers in combat. This article describes the work of researchers from the Army Research Laboratory on identifying a design that would allow an artificial nanomotor to take advantage of Brownian motion, the property of particles to move because they are warm.

When periodic arrays of metallic nanostructures are illuminated with light, each of the nanoparticles produces a strong response, which, in turn, results in enormous collective behaviors if all of the particles can interact. Scientists at The University of New Mexico have found that decreasing the density of nanoparticles in the array produces field enhancements that are not only larger, but extend farther away from the array.

A team of researchers has found a new way to produce a polymer material called PBO, a product known commercially as Zylon that's used in bulletproof vests and other high-performance fabrics. The new approach could be useful in making PBO products that resist degradation, a problem that has plagued PBO-based materials in the past.

Rice University scientists have transformed their laser-induced graphene into self-sterilizing filters that grab pathogens out of the air and kill them with small pulses of electricity. The flexible filter may be of special interest to hospitals.

Research led by University of Texas at Dallas physicists has altered the understanding of the fundamental properties of perovskite crystals, a class of materials with great potential as solar cells and light emitters. In particular, the study presents evidence questioning existing models of the behavior of perovskites on the quantum level.
