CFC replacements cause vast ‘forever chemical’ pollution – new research

Concentrations of a forever chemical known as TFA is increasing in rainwater, drinking water, soil and plants.

Climate ‘fingerprints’ mark human activity from the top of the atmosphere to the bottom of the ocean

The ocean is warming as the upper atmosphere is cooling – both as a result of excessive greenhouse gas emissions.

An Open-Cavity Gas Pressure Sensor Based on Vernier Effect of Twin-Hole and Dual-Core Fiber Fabry–Perot Interferometer

Abstract: An open-cavity optical fiber gas pressure sensor based on the Vernier effect is proposed. The sensor consists of two Fabry-Perot interferometers (FPIs) connected in parallel. As a sensing ...
