We describe a technique for measuring chemical shift anisotropy (CSA) lineshapes in NMR spectra of polycrystalline or amorphous solids.

Thermoelectric modules (TEMs) are solid-state devices used for cooling, heating and power generation.
From measurements of absorption and phase shift of microwaves passing through a discharge, several wavelengths long, in a waveguide the electron densities and collision frequencies may be deduced i
Recent advances in the interpretation of optical emission spectra from plasmas have made it possible to measure parameters such as electron temperature (T-g), relative electron density, and gas tem
Recent advances in the interpretation of optical emission spectra from plasmas has made it possible to measure parameters such as electron temperature (T sub e), relative electron density, and gas
X-ray sensitivity ("Cliff-Lorimer" k-) factors have been determined for a limited number of elements including oxygen, on an ultra- thin window (UTW) Si(Li) energy dispersive X-ray detector interf
A new technique is described through which the refractive index and extinction coefficient of an isotropic solid can be determined using measurements of normal incidence reflectance and pseudo- Bre
The blood oxygenation level-dependent (BOLD) effect in functional magnetic resonance imaging depends on at least partial uncoupling between cerebral blood flow (CBF) and cerebral metabolic rate of
For many years antioxidants and other additives have been employed to improve the thermoxidative stability of polymers.
