The V-650 is a double-beam spectrophotometer with a photomultiplier tube (PMT) detector. The high sensitivity of the PMT enables accurate measurements of low (and high) concentration samples. By ...

The V-630 is an economical, general-purpose instrument with a compact design to save bench space. Its excellent spectroscopic performance is suitable for routine, QC and research applications.

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

We investigate the effect of molecular geometry and conformational flexibility on electronic coupling and charge transfer interactions within propeller-shaped perylene diimide (PDI) tetramer arrays ...

The article considers creating Laser Opto-Electronic Airspace Monitoring System in the visible and infrared ranges and its practical applications in airspace security, trajectory measurements and ...

In isolated, catalytically inactive, DNA photolyase from Escherichia coli (E. coli), the flavin adenine dinucleotide cofactor is in its neutral radical state FADH•. It can be activated by a unique ...
