Physicists have developed a spectral-filtering technique that strips away unwanted extra photons from quantum light sources, tackling one of the most persistent obstacles in quantum optics. The method ...

A team of scientists at the Tufts University School of Engineering has developed a new filtering technology. Inspired by biology, it could help curb a drinking water-related disease that affects tens ...

The chemicals known as PFAS are considered a severe threat to human health. Among other things, they can cause liver damage, cancer, and hormonal disorders. Researchers at the Technical University of ...

The adaptive block size processing method in different image areas makes block-matching and 3D-filtering (BM3D) have a very good image denoising effect. Based on these observation, in this paper, we ...

Water-conducting fractured zones in a rock mass can cause problems in mining. Attempts have been made to monitor their development using microseismic signals. However, due to the lack of prior ...

Discover how a new gel-based filter material uses electric charges to trap a dangerous "forever chemical" pollutant.

Researchers create thin film polymer membranes capable of separating fluoride from chloride and other ions. Targeted ion selectivity by the filtering membranes could have important implications for ...
