Laser treatment found to boost battery performance

As the world transitions to renewable power sources such as solar and wind, there is a growing need for high-performance rechargeable batteries to store the energy generated by this intermittent energy source. Today's lithium-ion ...

New nanoparticle source generates high-frequency light

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength—and the shorter the wavelength, the smaller the objects and details the light can be used to see.

Light-induced acceleration of intracellular delivery

Cell membranes are barriers that maintain cellular homeostasis, and the intracellular delivery of biologically functional molecules, including peptides, proteins, and nucleic acids to manipulate cellular functions. Conventional ...

An X-ray step towards superfast nanoelectronics

When a material with magnetic properties, constructed from appropriately selected layers, is illuminated by a pulse from an X-ray laser, it instantly demagnetizes. This phenomenon, so far poorly understood, could in the future ...

Metastable states of floating crystals

A research team led by the GRASP—Group of Research and Applications in Statistical Physics—at the University of Liège (Belgium), demonstrates how to manipulate the mesh, shape and symmetry of floating crystals by wandering, ...

Mixing laser beams and X-ray beams

Unlike fictional laser swords, real laser beams do not interact with each other when they cross—unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing ...

Creating frequency combs in microresonators

For the first time, scientists were able to create ultrashort dark and bright light pulses that are linked together in tiny glass rings called microresonators. Each of the flashes consist of many different, precisely defined ...

New compact terahertz laser with 120 frequencies

Researchers have taken a major step towards bringing terahertz frequencies out of their hard-to-reach region of the electromagnetic spectrum and into everyday applications. In a new paper, the researchers demonstrate a first-of-its-kind ...
