... epifluorescence microscopy, light from a UV-vis light source is passed through an excitation filter and a dichroic mirror, then the fluorescence emitted from the sample is passed back to the dichroic mirror and through an emission filter to the ocular lens or camera. Immunohistochemical methods ...

... voltage-sensitive dyes in polymer spheres just 30 nanometers in diameter. When illuminated with blue light, the voltage-sensitive dyes emit a mixture of red and green light; the exact frequency of light emitted is influenced by the strength of local electric fields, allowing the researchers ...

... there is plenty of it in tectonic vibrations and heat around... Feeding with pure heat looks even less probable... But remember that these objects emit thermal infrared - of a few micrometers wavelength. We are thinking to use this energy in practice (like powering MP3 players) in much smaller ...

... considered safer to use a camera and to pilot the microscope from that. And mith, FYI, many fluorophores are excited with UV' although they may emit in the visible spectrum.

... However, when you say cars using hydrogen = less emissions of carbon, that is absolutely correct. BUT, that is not my point - hydrogen cars still emit green house gases (water vapor), and if everyone switches to hydrogen cars, we are going to have a similar problem. I did not look at the average ...
