The Shibata shift was analyzed in flash irradiated wheat (Triticum aestivum, L., cult. MV17) leaf homogenates in the pressure range of 0.1 to 500 MPa, at temperatures of 20, 30 and 40 degrees C. The kinetics of the blue shift (called Shibata shift in case of intact leaves) was followed by repeated recording of fluorescence emission spectra after ...

Proceedings of the 37th ACM International Conference on the Design of Communication, 2019
Communication scholars employ metaphors to illustrate the ways that knowledge is produced in professional contexts. This poster argues that current metaphors casting professional texts in ecological and economical terms deserve reevaluation. To do this, it uses a content analysis of ethnographic notes from "ride-along" sessions and interviews with ...

The blue shift of the plasma edge of a ferromagnetic semimetal
Solid State Communications, 1998Abstract Magnetic measurements on nearly stoichiometric TbN single crystals reveal metamagnetic behavior with a T N of 31 K. Excess carriers due to nonstoichiometry make the crystals ferromagnetic with T C = 48 K, a fact which has been revealed by elastic neutron scattering measurements in zero applied field.

Red-, Blue-, or No-Shift in Hydrogen Bonds: A Unified Explanation
Journal of the American Chemical Society, 2007We provide a simple explanation for X-H bond contraction and the associated blue shift and decrease of intensity in IR spectrum of the so-called improper hydrogen bonds. This explanation organizes hydrogen bonds (HBs) with a seemingly random relationship between the X-H bond length (and IR frequency and its intensity) to its interaction energy.

Blue Shift of Photoluminescence Spectrum of Porous InP
ECS Transactions, 2010The samples of porous InP were grown up by a method of anode etching on a substrate (100) InP n-type. The samples were characterized by SEM and photoluminescence (PL) where a blue shift was observed in PL. To remove surface oxides from the surface of porous InP using the thermal cleaning of the samples in a stream of high purity hydrogen.

Localization of Electrons: Blue-shifting Hydrogen Bonds
Chemistry Letters, 2005Abstract A theory of electron localization is developed. Localization is caused by the interaction of an occupied orbital with a vacant orbital. Electrons localize in the occupied orbital rather than delocalize from the occupied orbital to the overlap region.

On the n-.pi.* blue shift accompanying solvation
Journal of the American Chemical Society, 1990It is well-known that compounds containing lone pairs undergo a blue shift (higher energy) in their n-π* electronic transition upon solvation. The reason generally put forth to explain such a blue shift is that the lone pair, because of its spacial extent, interacts with the solvent, either weakly, as in aprotic solvents, or strongly through the direct

Wavelength blue shifts in dye–polymer films
Journal of Optics A: Pure and Applied Optics, 2007Optical pumping of polymer films containing laser dyes results in emissions that exhibit spectral narrowing and wavelength shifting. Such films are fabricated on a substrate slice of silicon via a spin coating method. The thickness of the film is a few microns.

Origin of the annealing-induced blue-shift in GaAsSbN
2008 20th International Conference on Indium Phosphide and Related Materials, 2008Effects of the thermal annealing on the optical and structural properties of dilute nitride GaAsSbN epilayers, coherently grown on GaAs substrates by gas-source molecular beam epitaxy, have been investigated. Blue shift in the energy gap of the samples was observed when the annealing temperature was higher than 750degC.

Solvent effect on the type (red-shifted or blue-shifted) of hydrogen bond
Journal of Molecular Structure: THEOCHEM, 2006Abstract Solvent (liquid xenon) effect on the four hydrogen-bonded complexes F 3 C–H⋯NH 3 , F 3 C–H⋯N(CH 3 ) 3 , F 3 C–H⋯NCH, and F 3 C–H⋯O(CH 3 ) 2 as well as on the two intramolecular hydrogen-bonded configurations, TG(T∣G′) conformer of 1-methoxy-2-(dimethylamino)-ethane (in which the C–H⋯O hydrogen bond is involved) and Z -conformer of 2-( N ...
