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 ...

The tool enables continuous femtosecond measurements and resolves hidden kinetic components, revealing how structural ...

How do photosynthetic organisms harvest light so efficiently? To help answer this question, researchers have developed an ultrafast transient ...

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 ...

Researchers have unveiled three major microscopy innovations: a Caltech autofocusing method extending focus range hundreds-fold, an ultrafast absorption microscope revealing hidden photosynthetic ...

Japanese researchers have created an ultrafast transient absorption microscope with near single-molecule sensitivity, enabling unprecedented study of photosynthesis at femtosecond timescales. The ...

NIR femtosecond pulse (pump pulse) induces the electron oscillation, which is monitored by the extreme ultraviolet IAP (probe pulse) based on the transient absorption spectroscopy. Disclaimer: AAAS ...
