NIR spectrum of WASP-96 b

THe first transmission spectrum made from a single observation using Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) reveals atmospheric characteristics of the hot gas giant exoplanet WASP-96 b.

Heat maps of the confusion matrices of wheat and rice sample sets identified by the neural network

A Chinese team has developed a new algorithm for near infrared spectroscopy, suitable for high-throughput identification of the authenticity of crop varieties.

Diagram of the different acetylation states

Infrared and Raman spectroscopy have been used to identify lysine acetylation features, which provided a theoretical and experimental basis for the analysis of protein acetylation structures in biological systems.

Graphs showing the forecast for miniature spectrometers

A review of and prediction for the development of chip-based optical spectrometers.

Monolithic-waveform synthesis in the mid-IR range

An international team of laser physicists of the attoworld team at LMU and the Max Planck Institute of Quantum Optics has achieved unprecedented control over light pulses in the mid-infrared wavelength range.

The Gordon F. Kirkbright and Edward Steers awards are seeking nominations.

Diagram of the sardine effect

A spectrometer is being used to measure the MOF and guest molecule absorbance of two differently polarised types of infrared light, enabling the first measurement of both guest–guest and guest–host interactions in real-time.

Diagram of the new supercontinuum light source operation

A type of optical fibre with a refractive index that varies continuously across the fibre structure has been shown to yield a dramatic increase in supercontinuum power, while still preserving a smooth beam intensity profile.

Computational imaging technologies have substantially reduced the costs of imaging systems and at the same time significantly improved their performances. Use of a Lucy-Richardson-Rosen computational reconstruction method with infrared microspectroscopy has produced 3D images.

The Awards Committee of the Council for Near-Infrared Spectroscopy (CNIRS) is requesting nominations and submissions for four award categories.
