What is X-ray Absorption Spectroscopy (XAS)? X-ray Absorption Spectroscopy (XAS) is a powerful analytical technique that probes the local atomic and electronic structure of materials by measuring the ...

Fossil fuels are widely used in automobiles, industry, and power plants, but due to excessive use they are depleting at a rapid rate. This has prompted a search for renewable, sustainable, and ...

Flame Atomic Absorption Spectroscopy (FAAS) is a very popular analytical technique that has been employed by researchers for the elemental analysis of trace metals in a variety of samples. How does it ...

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 ...

What is Surface-Enhanced Infrared Absorption (SEIRA) Spectroscopy? Surface-enhanced infrared absorption (SEIRA) spectroscopy is an advanced analytical technique that combines the principles of ...

Scanning Tunneling Microscopes (STMs) are amazing tools which can manipulate singular atoms, but they cannot characterize these atoms as they act only on the outer electron shell. Meanwhile X-ray ...
