Â鶹ÒùÔºicists from Switzerland, Germany, and France have found that large-amplitude acoustic waves, launched by ultrashort laser pulses, can dynamically manipulate the optical response of semiconductors.
The first ever integrated nanoscale device which can be programmed with either photons or electrons has been developed by scientists in Harish Bhaskaran's Advanced Nanoscale Engineering research group at the University of ...
Researchers at Duke University have demonstrated photodetectors that could span an unprecedented range of light frequencies by using on-chip spectral filters created by tailored electromagnetic materials. The combination ...
The routine measurement of radiation doses can be clinically challenging due to limitations with conventional dosimeters used to measure the dose uptake of external ionizing radiation. In a new study, Karthik Pushpavanam ...
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have developed an optical switch that routes light from one computer chip to another in just 20 billionths of a second—faster ...
Scientists designed and connected two different artificial cells to each other to produce molecules called ATP (adenosine triphosphate). ATP is the fundamental unit that all living things use to carry and provide energy to ...
Electrons in atoms are pretty talented. They can form chemical bonds, get kicked out of the atom and even "jump" to different locations based on their energetic states.
What happens to a piece of metal when you shine light on it? This question, which has been one of the driving forces of modern physics, gained renewed interest in recent years, with the advances in fabrication of small metallic ...
Standards of food safety and food quality have never been higher in Germany and throughout the European Union. This is especially true in the dairy industry. Yet despite such high standards, traces of impurities, pesticides ...
Maiken Mikkelsen wants to change the world by developing a small, inexpensive hyperspectral camera to enable worldwide precision farming practices that would significantly reduce water, energy, fertilizer and pesticide use ...
