This work deals with the analysis of experimental data on the average magnetization of $Fe_{1-x}Me_x$ (Me=Sn,Si) disordered alloys, the average and local hyperfine fields (HFF) at the Fe nuclei. The effect of the metalloid concentration on the HFF is studied with the help of the results of first- principles calculatio…
The convergence of our understanding of structure-property relationships for selected biological macromolecules and our increased ability to prepare large synthetic macromolecules with a structural precision that approaches that of proteins have spawned a new area of research where chemistry and materials science join…
Abstract The present book is the second edition of Amikam Aharoni's Introduction to the Theory of Ferromagnetism, based on a popular lecture course. Like its predecessor, it serves a two-fold purpose: First, it is a textbook for first-year graduate and advanced undergraduate students in both physics and engineering. S…
A convective drying model is proposed which may be used to describe the drying behavior of leather. Using this model, the calculated transient leather temperature agrees well with experimental values. Variations in temperature and moisture content distribution are solved using the finite-difference method. The effects…
Polarized Cu K x-ray absorption near-edge structure spectra of CuO are measured and analyzed with the aim of extracting quadrupole and dipole partial spectral components. Theoretical spectral components are calculated within the framework of real-space multiple-scattering technique, relying on a non-self-consistent mu…
A novel method to reversibly modify the surface of gold nanoparticles is developed through electrostatic interaction between cationic tetraoctylammonium surfactant and anionic carboxylate groups. The particles can be extracted from the water phase into the toluene phase without aggregation after the adsorption of the…
Nanosize (5−7 nm) supported Co II Al-hydrotalcite-like compounds (Co II Al-HTlcs) on γ-Al 2 O 3 have been synthesized with a coprecipitation method in which the γ-Al 2 O 3 acts as a source of aluminum for coprecipitation and a support for the compound formation. The synthesis parameters identified are initial concentr…
Silylation reactions using liquid and supercritical CO 2 as the solvent were performed on both single surface (silicon wafers) and nanoporous (silica gel) silica samples. The alkylsilyl monolayers formed on single surfaces were characterized by wettability, ellipsometry, and X-ray photoelectron spectroscopy. Modified…
Partial Fischer esterification of poly(acrylic acid) allows tailoring of the hydrophobicity and charge density of multilayered films containing poly(allylamine hydrochloride) (PAH) and derivatized poly(acrylic acid) (d-PAA). As hydrophobicity and charge density strongly affect film permeability, control over these pro…
As high-throughput experimental techniques have become common in the area of materials research, entirely new types of experimental strategies have appeared. The kinds of problems, the desired outcomes, and the appropriate patterns are significantly different from those associated with conventional experimentation. Cl…
A few years ago we developed a new kinetic method for following transition-metal nanocluster formation in which the resultant nanocluster's catalytic activity was used as a reporter reaction via the pseudoelementary step concept. This method in turn yielded insights into a new, broadly applicable mechanism of nanoclus…
Hot solutions (>80 °C) of N -dodecanoyl- ( d - or l -) serine in toluene or water were cooled to room temperature to give gels and were then vitrified for cryo-TEM investigations. Electron micrographs showed multilamellar aggregates with a repetitive density profile of 33 Å as constituents of tubules and vesicles in t…
Adsorption and surface reactions of acetone vapor were observed on the title oxides at room and higher temperatures (up to 400 °C), using in situ infrared spectroscopy. The results were correlated with results of infrared spectroscopy of adsorbed pyridine, to assess impacts of the surface acid−base properties. It was…
For the implementation of internal dosimetry in workplaces based on individual monitoring, information that relates the measurement results with the intake of radionuclides is required. The present work provides electronic look-up tables as a PC based support system for internal dosimetry. The tables contain the compu…
We report a detailed study of the formation of semiconductor nanoparticles of the important compound ZnS and its Mn-doped variant ${\mathrm{Zn}}_{(1\ensuremath{-}x)}{\mathrm{Mn}}_{x}\mathrm{S}$ inside reverse micelle microreactors, by carefully varying the size of the reverse micelles at a fixed Mn concentration with…
We report on a comprehensive study of the electronic structure of the layered semiconductor $1T\ensuremath{-}{\mathrm{HfS}}_{2}.$ The occupied and unoccupied band structure has been investigated by combined angle-resolved photoemission and inverse photoemission. The results are discussed in the context of a fully rela…
The appearance of additional states of an impurity under high doping levels is discussed. On the basis of a Fermi level calculation, a model for the conductivity of heavily boron-doped diamond is proposed. This model allows one to reproduce the temperature dependence of the conductivity and of the Hall coefficient for…
The results of investigations of intercalated compounds ${\mathrm{Cr}}_{x}{\mathrm{TiSe}}_{2}$ and ${\mathrm{Co}}_{x}{\mathrm{TiSe}}_{2}$ by x-ray photoelectron spectroscopy and x-ray emission spectroscopy are presented. The data obtained are compared with theoretical results of spin-polarized band-structure calculati…
We simulate solidification in a narrow channel through the use of a phase-field model with an adaptive grid. In different regimes, we find that the solid can grow in fingerlike steady-state shapes, or become unstable, exhibiting unsteady growth. At low melt undercoolings, we find good agreement between our results, th…
A mean rate controllable random pulser to use for a random pulse train simulator is presented in this paper. The control of the men rate is practiced with a personal computer by referring to the look-up table of time-variant rate. The random pulser with present design can be used as a model to simulate the random puls…
