Miles Inside The Earth's Surface The insides of Earth remain as much of a mystery to experts as the outsides of the planet.

Abstract: A simple empirical formula is presented for computing the reflection coefficient of a rough-sea surface using windspeed, angle of incidence, and frequency as parameters. The formula closely ...

Based on single-nanowire surface photovoltage measurements and finite-element electrostatic simulations, we determine the surface state density, Ns, in individual n-type ZnO nanowires as a function of ...
