Electrons travelling through two slits and a single slit. (Courtesy: Herman Batelaan/New Journal of Physics) Physicists in the US and Canada say that they have done the best job yet of realizing ...

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...

Spectrometer optics involves measuring light intensity by means of a specialized analytical tool called a spectrometer which separates light by wavelength. Spectrometers are used for a variety of ...

The author examines dry dispersion and outlines the related analytical method development. Across the pharmaceutical industry, laser-diffraction technology is well established for particle-size ...
