Effective absorption of the energy of electromagnetic radiation is the cornerstone of a wide range of practical applications. Electromagnetic energy harvesting in the visible spectrum is very ...

At incredibly small scales, the universe operates according to the unfamiliar rules of quantum mechanics. And Planck’s ...

Researchers in the Oregon State University College of Engineering have developed new technology for uranium enrichment ...

They monitored the absorption on scales of 0.4 mm, 1 mm and 2 mm, that is, with the largest ‘volume element’ over 64 times bigger than the smallest. On the largest scale, the pattern of absorption ...

THE Klein-Nishina formula, which is based on the scattering and absorption of X- and -radiation by extra-nuclear electrons, has been widely used in the calculation of the absorption coefficients ...

A CORRESPONDENT, Mr. Harris Booth, has questioned the validity of the treatment of the absorption curve of cosmical radiation in water as given in my “Inter protation of the Atom”—in which ...

A research team from Penn State has broken a 165-year-old law of thermal radiation with unprecedented strength, setting the stage for more efficient energy harvesting, heat transfer and infrared ...
