Researchers from Aalto University and VTT Technical Research Centre of Finland have built a super-sensitive bolometer, a type of thermal radiation detector. The new radiation detector, made of a gold-palladium mixture makes it easier to measure the strength of electromagnetic radiation in real time.
LASER COMPONENTS USA, a specialized provider of laser and optoelectronic components in the US and Canada, and MIRTHE+ Photonics Sensing Center team up again to host a WORKshop on Infrared Technologies – this time at Princeton University on October 29 - 30. The latest developments for new detection materials, gas sensing instrumentation, LEDs and lasers, and spectroscopy innovations will be the focus during 30 presentations and nine dedicated Q&A networking sessions with leaders in the field.
As reported in Nature Physics, a Berkeley Lab-led team of physicists and materials scientists was the first to unambiguously observe and document the unique optical phenomena that occur in certain types of synthetic materials called moiré superlattices.
Quantum computers with the ability to perform complex calculations, encrypt data more securely and more quickly predict the spread of viruses, may be within closer reach thanks to a new discovery by Johns Hopkins researchers.
JA Solar has reached agreement with Shin-Etsu Chemical of Japan to license its intellectual properties of using Ga-doped silicon wafers for solar cell applications. Shin-Etsu Chemical holds a number of patents on doping Ga in silicon crystals and using the Ga-doped p-type crystalline silicon wafers for making solar cells.
The international team, including researchers from the University of Cambridge, sent high-frequency sound waves across a modified semiconductor device to direct the behaviour of a single electron, with efficiencies in excess of 99%.
An international team of scientists led by researchers from the Laboratory of Nanomaterials at the Skoltech Center for Photonics and Quantum Materials (CPQM) has shown that the nonlinear optical response of carbon nanotubes can be controlled by electrochemical gating.
Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings.
Controlling the interactions between light and matter has been a long-standing ambition for scientists seeking to develop and advance numerous technologies that are fundamental to society.
Quantum effects are genuinely found in the world of nanostructures and allow a wide variety of new technological applications. For example, a quantum computer could in the future solve problems, which conventional computers need a lot of time to handle.
