IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it into electrical signals. There are two main types of sensors: ...

An international team of researchers, led by Drexel University, has found that a thin coating of MXene — a type of two-dimensional nanomaterial discovered and studied at Drexel for more than a decade ...

While a mosquito bite is often no more than a temporary bother, in many parts of the world it can be scary. One mosquito species, Aedes aegypti, spreads the viruses that cause over 100,000,000 cases ...

Infrared (IR) spectroscopy, alternatively referred to as vibrational spectroscopy, is an analytical technique used in chemical and physical sciences. This spectroscopic technique measures how samples ...
