A SULPHONATION product of hydrochinol (1,4-dihydroxybenzene) described as 1,4-dihydroxybenzene disulphonic acid, or disulpho-hydrqchinol, shows in an alkaline medium a strong blue fluorescence, ...

Biological membranes, such as those surrounding animal cells, are made up of lipids and proteins. Because these molecules do not usually mix well, they are distributed within different regions of the ...

Most scorpions glow a blue-green color when illuminated by ultraviolet light or natural moonlight. Scientists aren't sure how this fluorescence benefits the creatures, but some have speculated that it ...

The displays of mobile devices are inherently wasteful. Hund’s rule—a quantum-mechanical principle formulated nearly a century ago—dictates that for every excited fluorescent molecule that radiates ...

If you're looking for a gift to dazzle a special someone, and regular flowers just don't seem like enough to do the trick, how about creating a beautiful bouquet that can "glow" in the dark? The ...

This method uses fluorescence to analyze the samples. In fluorescence, the fluorophore absorbs light of a certain wavelength, which then excites the electron, which moves from ground state to a high ...
