By: Ingo Stotz, Grazia Lamanna, Harald Hettrich, Bernhard Weigand, and Johan Steelant

Description: A double diaphragm shock tube facility for studying liquid-spray atomization and combustion-related phenomena at elevated pressures and temperatures is described. The present shock tube is specifically intended for the investigation of fundamental processes related to fluid disintegration and mixing under realistic engine conditions. Special features of the facility include a variable-area driver section to compensate for shock attenuation, a square test sec...

By: N. H. March and Á. Nagy

Description: Following some studies of ∫ n(r)∇V(r)dr by earlier workers for the density functional theory (DFT) one-body potential V(r) generating the exact ground-state density, we consider here the special case of spherical atoms. The starting point is the differential virial theorem, which is used, as well as the Hiller–Sucher–Feinberg [ Phys. Rev. A 18, 2399 (1978) ] identity to show that the scalar quantity paralleling the above vector integral, namely, ∫ n(r)∂V(r)/...

By: M. Chen, A. Pukhov, Z. M. Sheng, and X. Q. Yan

Description: Ion acceleration by circularly polarized laser pulses interacting with foil targets is studied using two dimensional particle-in-cell simulations. It is shown that laser pulses with transverse super-Gaussian profile help in avoiding target deformation as compared with the usual Gaussian pulse. This improves monochromaticity of the accelerated ion spectrum. Two kinds of surface instabilities have been found during the interaction. These instabilities can pote...

Description: Nanomechanical tests of bending flexibility, kinking, and buckling failure characterization of vertically aligned single crystal ZnO nanorods/nanowires were performed quantitatively by nanoindentation technique. These nanostructures were grown by the vapor liquid solid (VLS) method, a relatively high temperature approach, and the aqueous chemical growth (ACG) method, a relatively low temperature approach on different substrates, including SiC and Si. The fir...

By: Jun-Ho Lee, Ji Young Lee, and Jun-Hyung Cho

Description: Using first-principles density-functional calculations, we investigate the reaction of acetone on the Si(001) surface, which exhibits the conversion from a kinetically controlled reaction to thermodynamically controlled one by means of thermal anneal or the highly confined electron beam of the scanning tunneling microscopy (STM) tip. We identified the four different reaction pathways forming not only two kinds of di-σ structures on top of a single Si dimer (...

By: Aurélien Perera

Description: The hard Gaussian overlap (HGO) model for ellipsoids is compared to the hard ellipsoid of revolution (HER) model, in the isotropic fluid phase and within the framework of the Percus–Yevick (PY) and hypernetted chain (HNC) integral equation theories. The former model is often used in place of the latter in many approximate theories. Since the HGO model slightly overestimates the contact distance when the two ellipsoids are perpendicular to each other, it lead...

By: M. Eletta Negretti, Scott A. Socolofsky, and Gerhard H. Jirka

Description: Two-layer stratified flows are commonly observed in geophysical and environmental contexts. At the interface between the two layers, both velocity shear and buoyancy interplay, resulting in various modes of instability. Results from a temporal linear stability analysis of a two-layer stratified exchange flow under the action of a mean advection are presented, investigating the effect of a mild bottom slope on the stability of the interface. The spatial accel...

By: Zhi Wen Tan, Su Gui Gisela Teo, and Junhui Hu

Description: We show that a hypodermic needle can generate and rotate a small droplet of water around its needle tip when the hypodermic needle is mechanically driven by an acoustic needle. The water droplet increases in size with the driving time and begins to rotate around the tip of the hypodermic needle when the diameter of the droplet is large enough. The rotating droplet falls off when its diameter is larger than a critical value of several millimeters. For a given...

Description: The effect of substrate pretreatments such as ultrasonication or scratching by diamond powder on the microstructure and field emission characteristics of diamond grown over silicon and macroporous (anodized) silicon substrates was investigated. These films were grown in a hot filament chemical vapor deposition (CVD) system. Scanning electron microscope (SEM) studies revealed that ultrasonic pretreatment of the substrates increases nucleation density of CVD d...

By: V. V. Laguta, M. Nikl, J. Rosa, B. V. Grinyov, L. L. Nagornaya et al

Description: The self-trapping of holes at oxygen anions was studied by electron spin resonance in UV irradiated CdWO4 crystals. Analysis of superhyperfine interaction of the holes with 183W and 111,113Cd isotopes shows that the self-trapped hole is either delocalized in the space between two energetically equivalent nearest neighbor oxygen ions or tunnels between them. When the temperature increases above 40–50 K the self-trapped holes are thermally liberated and can be...

By: C. Nguyen, X. Garbet, and A. I. Smolyakov

Description: In the present paper, we compare two modes with frequencies belonging to the acoustic frequency range: the geodesic acoustic mode (GAM) and the Beta Alfvén eigenmode (BAE). For this, a variational gyrokinetic energy principle coupled to a Fourier sidebands expansion is developed. High order finite Larmor radius and finite orbit width effects are kept. Their impact on the mode structures and on the Alfvén spectrum is calculated and discussed. We show that in ...

Description: We report on single dot microphotoluminescence (μPL) emission at low temperature and low power from InAs dots grown by molecular beam epitaxy in nanoscale holes of a SiO2 mask deposited on GaAs(001). By comparing atomic force microscopy measurements with μPL data, we show that the dot sizes inside the nanoholes are smaller than those of the dots nucleated on the extended GaAs surface. PL of dots spans a wide energy range depending on their size and on the th...
