Although we generally assume that opacity is the normal look for animals like us humans, this factoid is only correct for as long as you maintain the dissimilar optical refraction indices of skin and ...

If you studied advanced physics at high school, there's a good chance that you remember Snell's law, which states how a ray of light bends when it crosses a boundary between two media. According to ...

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 ...

Utilizing Index of Refraction Monitors in Biopharmaceutical Downstream Processing and Purification When the FDA published the 2003 document, “Pharmaceutical Current Good Manufacturing Practices (CGMPs ...

Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...

Researchers used ultrasonography, phakometry, keratometry, pachymetry, interferometry, anterior segment optical coherence tomography and high-resolution MRI on the right eyes of 91 adults, according ...

Researchers at Beijing University of Chemical Technology (BUCT) and BOE Technology Group Co., Ltd. (BOE) have developed a novel type of transparent organic–inorganic hybrid photoresist with highly ...
