Scientists have engineered a nanoscale switch using DNA "origami." Inspired by macroscale mechanical switches, the device achieves long-term functionality without the continuous forcing mechanism that past versions required ...
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 ...
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 ...
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 ...
To capture a crisp image of a hummingbird in flight, which can flap its wings up to 200 times per second, a photographer needs a camera with an extremely fast shutter speed. But what if your target is smaller than a single ...
Conventional spontaneous Raman spectroscopy of interfacial molecules typically requires plasmonic or electronic enhancement, limiting accessible systems. A nonlinear coherent Raman method now enables direct, high sensitivity ...
Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics that enables high-efficiency optical signal control within a small device footprint. The development ...
Today, I want to walk you through a deceptively simple innovation from the lab at Loughborough University (PI: Prof Marco Peccianti): what happens when we decorate a spintronic heterostructure with a sparse layer of plasmonic ...
Light, as we usually conceive of it, is defined by the astonishing velocity at which it moves from one point to another. For example, in just one second, light can travel most of the distance between Earth and the moon. This ...
