We have investigated the magnetic transition and magnetic structure of triple-layered ruthenate Sr4Ru3O10 directly using neutron scattering techniques. Only one ferromagnetic phase is observed, and previously proposed antiferromagnetic phase transitions are ruled out. The complex anisotropic magnetotransport, magnetiz…
Thermal scaling and relaxation of the interface width in an electrophoretic deposition of polymer chains is examined by a three-dimensional Monte Carlo simulation on a discrete lattice. Variation of the equilibrium interface width $W_r$ with the temperature $T$ shows deroughening $W_r \propto T^{-δ}$, with $δ\sim 1/4$…
In this paper the relationship between the density functional theory of freezing and phase field modeling is examined. More specifically a connection is made between the correlation functions that enter density functional theory and the free energy functionals used in phase field crystal modeling and standard models o…
We have investigated the structural, magnetic, thermodynamic, and dielectric properties of polycrystalline ${\mathrm{CoCr}}_{2}{\mathrm{O}}_{4}$, an insulating spinel exhibiting both ferrimagnetic and spiral magnetic structures. Below ${T}_{c}=94\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ the sample develops long-range fer…
Single phase (001)-oriented ${\mathrm{BiFeO}}_{3}$ (BFO) thin films grown by pulsed laser deposition can only be obtained in a narrow window of deposition pressure and temperature and have a low magnetic moment. Out of the stability window Fe- or Bi-rich impurity phases form, which has a strong impact on the physical…
ABSTRACT: Monosaccharides have several hydroxyl groups and a compatible structure with starch polymers resulting in effective plasticization in starch films. Two groups of plasticizers (polyols and monosaccharides) were used to compare their plasticizing efficiency. Fructose, glucose, mannose, galactose, glycerol, sor…
Current oxide nanomaterials knowledge to draw from and build on Synthesis, Properties, and Applications of Oxide Nanomaterials summarizes the existing knowledge in oxide-based materials research. It gives researchers one comprehensive resource that consolidates general theoretical knowledge alongside practical applica…

Levchik). 1.1 Introduction. 1.2 Polymer Combustion and Testing. 1.3 Flame Retardancy. 1.4 Conclusions and Future Outlook. References. 2 Fundamentals of Polymer Nanocomposite Technology (E. Manias, G. Polizos, H. Nakajima, and M.…
Abstract Biocomposites offer a significant non‐food market for crop‐derived fibres and resins. Considerable growth has been seen in the use of biocomposites in the automotive and decking markets over the past decade or so, but application in other sectors has hitherto been limited. Nevertheless, with suitable developm…
We show that an electrostatically created $n\text{\ensuremath{-}}p$ junction separating the electron and hole gas regions in a graphene monolayer transmits only those quasiparticles that approach it almost perpendicularly to the $n\text{\ensuremath{-}}p$ interface. Such a selective transmission of carriers by a single…
First-principles electronic-structure computes the lattice and elastic constants of single-crystal TiB and NbB and changes with Nb, Ti, Al, and V solutes. The data is built into an interpolation formula for lattice and elastic constants of the quartenary (TiNbAlV)B with dilute Al and V concentrations. The lattice and…
Processing through the application of severe plastic deformation (SPD) has become important over the last decade because it is now recognized that it provides a simple procedure for producing fully-dense bulk metals with grain sizes lying typically in the submicrometer range. There are two major procedures for SPD pro…
The process of severe plastic deformation (SPD) makes it possible to reduce the grain size to the submicrometer or nanometer range in many metallic materials. When the SPD process is applied to age hardenable alloys, it may also be possible to control aging behavior. In this study, a technique of equal-channel angular…
The crystallographic slip activity in several grains deformed by simple tension is determined by use of in-situ deformation in combination with Electron Back Scattering Diffraction (EBSD)-investigations and Secondary Electron (SE) imaging. This technique is also used to determine grain lattice rotation paths of grains…
While dealing with photonics, we find that user-controllable electro-optical devices are of great importance. In this paper, the optical control of the light scattering properties of polymer-dispersed liquid crystals has been achieved by dissolving a photoconductive material in the polymer matrix. In the dark, an elec…
The effect of light soaking (LS) on nanocrystalline porous silicon (nc-Si) is found to depend on the ambient conditions. Light soaking in air decreases the photoluminescence (PL) intensity and increases the number of dangling bond density measured by electron spin resonance (ESR) monotonically as the exposure time is…
The program SITCOM , which can be used to facilitate the comparison of macromolecular substructures from different sources for validation purposes and to construct a consensus model containing sites from different substructures, is described.
Electromigration (EM) reliability of Cu/low-k interconnects with a conventional preclean-first process, and an advanced barrier-first process has been investigated. Compared with the preclean-first process, extrinsic early failures were not observed for the barrier-first process. This suggests that process-induced def…
A hot dip aluminizing process to simulate the continuous galvanizing line (CGL) was carried out in three successive steps by a hot dip simulator: the pre-treatment for removing scales on the 200 × 250 mm2 and 1mm in thickness cold rolled steel sheet, the dipping in 660°C Al-Si melt for 3s and the cooling. In a pre-tre…
A biomimetic supported liquid membrane (SLM) system was employed to control the morphology of strontium carbonate. Some interesting morphologies, including rods, shuttles and spheres, can be readily generated by using citric acid, nitrilotriacetic acid and ethylenediaminetetraacetic acid as cooperative modifiers in th…
