The peak frequency of the terahertz radiation generated from femtosecond laser-induced air plasmas is blue shifted with increased second harmonics intensity when a high voltage added upon plasmas. This shift result DC-biased field plus AC-biased harmonics, indicating that this tunable by varying two components. significant to various applications such as remote sensing and material characteriza...

Inrat liver microsomal fractions oxidation of adrenaline was effected by superoxide anion radicals (A), whereas cytochrome c, 2,6-dichlorophenol-indophenol and ferricyanide accepted electrons from NADPH-specific filavoprotein only directly. Nitro Blue Tetrazolium was reduced both by 02and by tbe direct acceptance of electrons. Elevation ofpH and addition of menadione shift the Nitro Blue Tetraz...

A new method by using a pulsed-laser Raman scattering technique was employed to estimate junction temperature of a fluorescence-resin-less blue-LED package. Temperature dependent Raman shift of E2 H mode of GaN layer in the blue-LED were obtained and were in good agreement with the experimental data published by the other researchers. This technique was applied to estimation of a junction tempe...

interaction of glucose 6-phosphate dehydrogenase from s. aureofaciens with nad+, nadp+and glucose 6-phosphate were investigated using different fluorescent probes. binding of nad+, nadp+and s-nadph to the native enzyme quenched intrinsic protein fluorescence by 100%, 10% and 21%,respectively, from which kd values of nad+ (6.5 mm), nadp+ (92.0 μm) and s-nadph (122.0 μm)were calculated. binding o...

We investigated the field-induced Shift of the blue phase diffraction bands. The temperature dependence of the electrostriction tensor components is determined for the first time. In the blue phase BPI at constant field strength E fl [001], a change of the temperture leads to a change of both the unit cell volume and its shape. The deformation of the unit cell displays a pretransitional behavio...

direction (blue) introduce a phase shift from echo to echo that increases with the distance form the isocenter. (b, c) Schematic example for acquiring three ROIs with two of them (ROIs B and C) overlapping with a conventional projection (dashed gray). With the phase shifts introduced by the blip gradients in the slice direction, the projection direction (dashed blue) is tilted by an angle that ...

PbS quantum dots synthesized at room temperature through CBD technique show a large blue shift of absorption edge due to formation of very small particle size of the order of 2nm confirmed by HRTEM measurement. It exhibits a further blue shift when synthesized in acidic medium (pH 5.5) whereas a red shift for those synthesized in alkaline medium (pH 9.5) on rise of growth temperature up to 355K...

Photoluminescence, its excitation power dependence, and Raman scattering spectra have been studied in CdSe/ZnS and CdSeTe/ZnS QDs for the nonconjugated states and after the QD conjugation to the anti-Interleukin-10, Human papilloma virus and Pseudo rabies virus antibodies. The QD bioconjugation to charged antibodies stimulates the “blue” energy shift of PL bands related to exciton emission in t...
