Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Few people today would dispute that the use of Mie Theory provides the only route to accurate particle size analysis when measuring fine particles using laser diffraction. The international standard ...

Light scattering as the basis for size determination of many objects has been explored for a long time. It was Gustav Mie, author of the Mie Scattering Theory, who studied gold nanoparticles in ...

Refractometers are versatile in their design and use, and are able to provide results as refractive indices, or in other cases, as direct measurements of parameters such as soluble solids, sugar ...

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

Physicists are involved in an unusually heated debate over the reality of a new kind of refraction and about the possibility of making perfect lenses. Edwin Cartlidge reports. If you think science is ...
