Ultrafast extreme ultraviolet (XUV) spectroscopy is a powerful technique for probing the dynamics of atoms and molecules with attosecond time resolution. However, conventional XUV absorption ...

Attosecond transient absorption spectroscopy (ATAS) is an advanced technique that enables the direct observation of electron dynamics on the attosecond (10⁻¹⁸ second) timescale. By utilising isolated ...

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 ...

The sample generates the capacitance transient, which is then measured by the instrument. A temperature sweep is applied while employing a lock-in technique. Subsequently, the instrument filters out ...

The top panel illustrates halide substitution in cesium lead halide (CsPb(Br/Cl)₃) nanocrystals, where photoirradiation induces exchange between bromide and chloride ions, altering the Br/Cl ratio.

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

A photosensitizer (PS) is a chemical species that initiates a reaction upon absorption of light. Although the chemical compositions and practical applications of PS' differ widely, they all follow the ...

A team at the Institute for Basic Science (IBS) Center for Molecular Spectroscopy and Dynamics (CMSD) has developed a new spectroscopic technique to monitor changes in perovskite nanomaterials in real ...

Scientists at the University of Cambridge have discovered that electrons can be fired across solar cell materials in just 18 ...

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 ...
