The technology could be deployed on the ISS, geostationary satellites or even sent to other planets to map their gravity
In orbit, in the air or even on the ground, photonics technologies give us a precise big picture on climate change, discovers Ben Skuse
The technology will help the oil & gas industry meet its compliance and regulatory obligations, as well as help transition towards more sustainable operations
Superluminescent LED drivers can help us understand ocean turbulence, here’s how
Susan Curtis explores the new breed of quantum gravimeters finding their way onto the slopes of Mount Etna and into tunnels deep under Birmingham

Abigail Williams speaks to scientists tracking marine plastic using satellite spectral imagery
The partners are evaluating and testing a novel surface-enhanced Raman spectroscopy substrate for trace detection of materials.
Thermal infrared hyperspectral imaging is well suited for the detection, identification, and quantification of industrial stack gas emissions. This application note describes a measurement campaign performed at the Port of Rotterdam with the Telops Hyper-Cam, a commercial high-performance, FTIR-based hyperspectral imaging instrument. Principles of gas detection, quantification, and identification are discussed and computed mass-flow rate results are presented from data acquired at a commercial alkene production facility.
