background: dielectric barrier discharge (dbd), a source of non-thermal plasma, is used in surface decontamination. objective: to study the effect of dbd plasma treatment, we evaluated the effect of plasma exposure time on inactivation of bacillus subtilis. results: applying the dbd plasma to the culture of b. subtilis caused complete sterilization of the surface without any thermal effects. in...

In this paper we provide an general derivation of the non-thermal Sunyaev-Zel’dovich (SZ) effect in galaxy clusters which is exact in the Thomson limit to any approximation order in the optical depth τ . The general approach we use allows also to obtain an exact derivation of the thermal SZ effect in a self-consistent framework. Such a general derivation is obtained using the full relativistic ...

Debris cover is widely present in glacier ablation areas of the Tibetan Plateau, and its spatial distribution greatly affects glacier melt rates. High-resolution in situ measurements of debris thickness on Hailuogou glacier, Mount Gongga, southeastern Tibetan Plateau, show pronounced inhomogeneous debris distribution. An analysis of transverse and longitudinal profiles indicates that the ground...

Article history: Received 18 March 2016 Revised 16 July 2016 Accepted in revised form 28 July 2016 Available online xxxx Photoluminescence piezospectroscopy (PLPS) was used as a non-destructive technique for the measurement of residual stresses within the thermally grown oxide (TGO) layer beneath plasma-spray thermal barrier coatings (TBC). The technique has proved to be very effective for such...

Lead chalcogenides such as PbS, PbSe, and PbTe are of interest for their exceptional thermoelectric properties and strongly anharmonic lattice dynamics. Although PbTe has received the most attention, PbSe has a lower thermal conductivity and a nonlinear temperature dependence of thermal resistivity despite being stiffer, trends that prior first-principles calculations have not fully reproduced....

Introduction: Two-dimensional (2D)-phased vertical cavity surface-emitting laser (VCSEL) arrays offer unique advantages for scaling up single-mode power for high-brightness applications such as fibre laser pumps. They tend, however, to operate in the undesirable out-of-phase mode, which has an on-axis null in the far field [1]. In-phase VCSEL arrays with an on-axis maximum in the far field have...

The thermal diffusion factor, aT, for a binary gas mixture is calculated on the basis of nonequilibrium thermodynamics. A new formula for aT is derived and this factor is given for several paris of gases according to this formula.

The mechanical properties of microscopic particles have been a heated research object for it takes the deformation of micro-beads in the microfluidic environment into account. Sufficient knowledge on mechanical properties of micro-beads would lead to better device design and application for cell mechanics, tissue engineering, etc. The physical properties of alginate beads were examined both in ...

To study the effect of twin boundaries on thermal transmission, thermal conductivities of twinned diamond with different twin thicknesses have been studied by NEMD simulation. Results indicate that twin boundaries show a weak phonon scattering effect on thermal transmission, which is only caused by the additional twin boundaries' thermal resistance. Moreover, according to phonon kinetic theory,...

oil in water emulsions have attracted considerable attention in food industry due to their large applications. in this study, the effect of thermal treatment on oil in water emulsions (o/w) containing 40% oil was studied. the emulsions were prepared using xanthan gum, guar gum and carboxymethyl cellulose as stabilizer and polyoxyethylen sorbitan monooleat as emulsifier. a mixture design was use...
