Optical photothermal infrared (O-PTIR) spectroscopy is an infrared super-resolution measurement technique where a shorter ...

Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

Due to increasing environmental pollutants and global industrialization, food and water safety have become crucial concerns today. Ensuring that consumables are free from harmful contaminants is a ...

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

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 ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...

Researchers have developed a low-cost method for the analysis of interfacial molecules by combining ATR-IR with precise gap-control and multi-variate data analysis. A novel spectroscopic method ...

Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

*If you learn how to use atomic absorption spectroscopy (AAS), you can do accurate and reliable chemical research. But it takes practice and concentration to fully grasp its basic ideas. Understanding ...

The main objective of this randomized, double-blind, placebo-controlled study was to measure the impact of a multivitamin ...

Charge-carrier traps play a central role in the excited-state dynamics of semiconductor nanocrystals, but their influence is often difficult to measure directly. In CdS and CdSe nanorods of nonuniform ...
