The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Positron Annihilation Spectroscopy (PAS) is a highly sensitive, non-destructive method for probing atomic-scale imperfections in a broad spectrum of materials, from metals and ceramics to polymers and ...

Molecular rotational resonance (MRR) spectroscopy operates in the microwave region, detecting transitions between pure rotational energy levels. Combined with adiabatic cooling, MRR produces highly ...

Scientists have identified two polycyclic aromatic hydrocarbons—1- and 2-cyanonaphthalene—in interstellar space for the first time (Science 2021, DOI: 10.1126/science.abb7535). While many astronomers ...

Researchers developed a new method that allows, for the first time, to elucidate the chiral structure of molecules -- the exact spatial arrangement of the atoms -- by nuclear magnetic resonance (NMR) ...

Raman spectroscopy is an analytical technique that allows for the assessment of molecular structure and the identification of materials by examining the rotational and vibrational modes of molecules.

A research team led by Prof. GAO Xiaoming at the Anhui Institute of Optics and Fine Mechanics (AIOFM), Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS) recently ...

Faraday rotation spectroscopy (FRS) enables the detection of paramagnetic molecules by detecting changes in the polarization state of the linearly polarized light caused by a gaseous medium immersed ...

Infrared spectroscopy is widely used for identifying molecules and determining their structure, but the conventional one-dimensional technique does not work well with mixtures since peaks may overlap ...

Abstract: This article presents development of CMOS system-on-chip spectrometer processor for Spaceborne Earth Science, Planetary Science and Astronomy. The developed chip is intended for use in ...
