Analyzing energy potential

Sensors, radio transmitters and GPS modules all feature low power consumption. All it takes is a few milliwatts to run them. Energy from the environment - from sources such as light or vibrations - may be enough to meet these ...

Photovoltaic invention brings inventor acclaim

(PhysOrg.com) -- An invention by a South Dakota State University engineer could improve alternative energy technologies by making it easier for scientists to test new devices.

Liquid lens shrinks laser measuring device

Lasers are widely used in many areas of science, industry and medicine and the quality of the beams they produce needs to be measured to make sure they perform correctly. As electronic devices become smaller and smaller over ...

New sensor may soon test for coronavirus and flu simultaneously

The novel coronavirus has been compared to the flu almost from the moment it emerged in late 2019. They share a variety of symptoms, and in many cases, an influenza test is part of the process for diagnosing COVID-19.

Low-cost sensor records the level of rivers

Researchers at the University of Bonn have developed a method that allows the water level of rivers to be monitored around the clock. The cost-effective sensor is for instance suitable for area-wide flood warning systems. ...

New technique measures evaporation globally

Researchers at Columbia Engineering and Boston University have developed the first method to map evaporation globally using weather stations, which will help scientists evaluate water resource management, assess recent trends ...

Bendable crystals resolve properties of X-ray pulses

(Phys.org)—A frustrating flaw in a set of custom crystals for an instrument at SLAC National Accelerator Laboratory inspired a solution for an important scientific challenge: how to accurately measure the colors of each ...

'Nanotubes on a chip' could simplify optical power measurements

(Phys.org)—The National Institute of Standards and Technology (NIST) has demonstrated a novel chip-scale instrument made of carbon nanotubes that may simplify absolute measurements of laser power, especially the light signals ...
