The distribution of radial energy deposition around the track of carbon, aluminum, and iron ions with energy range from 10 MeV to 10 GeV inside silicon was calculated. A simple and direct approach was developed utilizing a corrected semianalytical model. The results of the present work agree very well with Monte Carlo…

Convection of adsorbed surfactant along a fluid particle surface can accumulate surfactant at the trailing end of the particle. The nonuniform surface tensions that result cause Marangoni stresses which retard the surface mobility. This is the second part of a two-part study on controlling the mobility of surfactant l…

Calculations of a total energy function are used to describe a theory of hysteresis effects in crystalline, ferromagnetic materials. This model is applied on the cubic structure of FeSi crystals, which are oriented in a (110)[001] texture. The magnetic energy of the crystal is separated in reversible and irreversible…
Summary The ElectroScan environmental scanning electron microscope (ESEM) enables wet samples to be observed by eliminating air but allowing water vapour into the sample chamber. However, evaporation from, and condensation on, the sample may occur during the pumpdown sequence used to reach this state, which means that…
<div class="htmlview paragraph">Studies have been conducted at Michigan Technological University (MTU) for over twenty years on methods for characterizing and controlling particulate emissions from heavy-duty diesel engines and the resulting effects on regulated and unregulated emissions. During that time, contr…
The three-dimensional structure of a ligand-free closed form of the glucose/galactose binding protein from Salmonella typhimurium has been determined at a resolution of 1.9 A. The crystallographic R-factor for the refined structure is 17.9%. The model contains all the atoms of the 309 residues of the protein sequence,…
High-purity aluminium nitride (AlN) powders of submicron size were consolidated to almost theoretical density in minutes at 1800°C using a plasma-activated sintering (PAS) process. The structure and microchemistry of grain boundaries in this polycrystalline material (average grain size, about 0.43 μm), sintered withou…
Abstract The adsorption of cadmium and zinc ions on natural bentonite heat‐treated at 110°C or at 200°C and on bentonite acid‐treated with H 2 SO 4 (concentrations: 0·5 mol dm −3 and 2·5 mol dm −3 ), from aqueous solution at 30°C has been studied. The adsorption isotherms corresponding to cadmium and zinc may be class…
Chirality in liquid crystal systems is a complex and sometimes difficult concept to understand and appreciate. In this article we review some of the reduced symmetry aspects of calamitic liquid crystal phases with reference to point symmetry, space symmetry, and helicity. We utilize these concepts in the discussion of…
A range of bright, multicolor phosphor systems for field emission displays is reported. These include the standard ZnO:Zn and newer, narrow band emitting systems based on green ZnGa2O4:Mn and red CaTiO3:Pr. A modified, blue emitting ZnO:(Zn/Mg) and thin films of ZnGa2O4:Mn have also been prepared.
This paper, the fifth in a series, is concerned with the experimental description of ultrafast electron diffraction \nand its application to several isolated chemical systems. We present a detailed description of the Caltech apparatus, which consists of a femtosecond laser system, a picosecond electron gun, and a…
The influence is studied of Co-Ti substituted Ba hexaferrite on the efficiency of the hexaferrite-magnetite-graphite triple absorbing system of fillers dispersed in a rubber matrix. Using the planned experiment technique, the optimal ratio is determined of its components, as well as their influence on the absorber's o…
A phase-field model which describes the solidification of a binary eutectic alloy with a simple symmetric phase diagram is introduced and the sharp-interface limit of this model is explored both analytically and numerically.
