Granular Gases

"Granular Gases" are diluted many-particle platforms during which the suggest loose course of the debris is way better than the common particle measurement, and the place particle collisions happen dissipatively. The dissipation of kinetic power may end up in results equivalent to the formation of clusters, anomalous diffusion and attribute surprise waves to call yet a number of.

Cosmic Explosions in Three Dimensions: Asymmetries in Supernovae and Gamma-Ray Bursts (2004)(en)(3

Highlights regimen supernova polarimetry and new insights into middle cave in and thermonuclear explosions.

Molecular Magnets: Physics and Applications

This publication offers an summary of the actual phenomena came upon in magnetic molecular fabrics during the last two decades. it really is written by means of best scientists having made crucial contributions to this energetic region of analysis. the most themes of this booklet are the rules of quantum tunneling and quantum coherence of single-molecule magnets (SMMs), phenomena which transcend the physics of person molecules, resembling the collective habit of arrays of SMMs, the physics of one-dimensional single–chain magnets and magnetism of SMMs grafted on substrates.

2 Raman spectroscopy is the measurement, as a function of wavenumber, of the inelastic light scattering that results from the excitation of vibrations in molecular and crystalline materials. The excitation source is a single line of a continuous gas laser, which permits optical microscope optics to be used for measurement of samples down to a few pm. Raman spectroscopy is sensitive to molecular and crystal structure; applications include chemical fingerprinting, examination of single grains in ceramics and rocks, single-crystal measurements, speciation of aqueous solutions, identification of compounds in bubbles and fluid inclusions, investigations of structure and strain states in polycrystalline ceramics, glasses, fibers, gels, and thin and thick films.

Physical quantities derivable from the measured parameter include the optical constants of bulk or filmed media, the thicknesses of films (from 1 to a few hundred nm), and the microstructural composition of a multiconstituent thin film. In general only materials with parallel interfaces, and with structural or chemical inhomogeneities on a scale less than about 1 / 10 the wavelength of the incident light, can be studied by ellipsometry. 1 The vibrational motions of the chemically bound constituents of matter have frequencies in the infrared regime.
