Closing wounds, burns and deep cuts isn't enough to kick-start healing. A wound needs a clean environment, free of bacterial infection and interruption. That calls for three components working together—one to kill bacteria, ...
Plants convert light into energy efficiently through photosynthesis—an ability that scientists and engineers still struggle to match with electronic devices. Recently, researchers have looked beyond traditional semiconductor ...
How could we noninvasively distinguish between healthy and cancerous tissue? And how could we increase the speed of wireless communications? These two seemingly unrelated questions may share the same answer: terahertz (THz) ...
Researchers at European XFEL, Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Rostock University and other collaborating institutions have used high-precision experiments to demonstrate that the most widely used models for the ...
How does light turn into motion within a metal? A team of researchers from European XFEL, the University of Potsdam and other participating institutions has shown that ultrashort optical laser pulses can trigger extremely ...
Aeron Tynes Hammack, a physicist by training and currently interim facility director of the Nanofabrication Facility at the Molecular Foundry, likes to work with nanoscale objects to better understand the world and solve ...
The terahertz (THz) frequency regime, sitting between microwaves and infrared light, has long promised revolutionary advances in wireless communication, security imaging and nondestructive sensing. A key roadblock, however, ...
Food waste is a nagging problem that weighs heavily on global food production, distribution and sales industries—but an emerging generation of AI sensors is providing a raft of fresh solutions. The embrace of AI in food industries ...
Physicists from Emory University have led work to develop a microscopic, nonlinear light source that can be switched on, off or tuned to a particular intensity by an electrical "knob." The paper is published in the journal ...
Gold nanoparticles, which are about one-thousandth the width of a human hair, can convert light they receive from a laser into heat. This capacity, known in medicine as photothermal therapy, is effective at destroying cancer ...
