A small team of chemists, having learned the secrets of light absorption from chlorophylls a and b, can now tune molecules to absorb anywhere in the solar spectrum. They are using this facility to ...

New Tools Bridge Gap between Single and Multiple Sample Absorbance Instruments For generations after Gustav Kirchhoff and Robert Bunsen deduced that almost all molecules in nature absorb and emit ...

UV-Vis spectroscopy is an analytical technique that measures the amount of discrete wavelengths of UV or visible light that are absorbed by or transmitted through a sample in comparison to a reference ...

Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...

Thermo Scientific™ Evolution™ UV-Visible Spectrophotometers with Thermo Scientific™ INSIGHT™ Software provide a reliable, simple-to-use solution for pharmacopeia compliance support. The EP and USP ...

Japan is pushing solar hydrogen into a new phase by teaching its materials to drink in colors of sunlight that used to go to waste. Instead of relying only on the most energetic visible wavelengths, ...

NanoDrop™ Microvolume UV-Vis Spectrophotometers from Thermo Scientific™ are robust, useful analytical tools, ideal for measuring absorbance when working with small sample volumes. Thermo Scientific ...
