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 ...

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

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

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 ...

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

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 ...
