Abstract The DepthCube™ 3D display is a solid‐state multi‐planar volumetric display system in which a DLP based high speed projector projects slices of the 3D scene onto a stack of LC scattering shutters acting as an electronically controlled projection volume. The scattering shutters are based on Polymer Stabilized C…
The corrosion products of zinc in an atmospheric environment in the presence of sodium chloride (NaCl) particles have been studied by in situ detection using Raman spectroscopy. Zinc plate with the NaCl precipitate at a density of 0.4 mg/cm2 was exposed for 3 days or longer in air with controlled relative humidity (RH…
The relation between the phase transition in the vicinity of 420 K discovered earlier and the formation of an incommensurate phase in the temperature range 410–460 K is established based on the X-ray, dielectric, and dilatometric studies of sodium niobate (NaNbO 3 ) single crystals and ceramics. It is also established…
Abstract Various substituted phenylthienyl perhydro‐ and perfluorocyclopentenes have been synthesized in order to compare their spectroscopic and photochromic properties. The difference in the electron densities of the central cyclopentene moieties in the perhydrocyclopentene and perfluorocyclopentene molecular switch…
Abstract Montmorillonite clay was organically modified by primary and quaternary ammonium salts (having C 12 -C 18 ). The modified clay was added to a solution of natural rubber in toluene at various contents. Characterization of the structure of the nanocomposites was performed by using x-ray diffraction and transmis…
Hydroxyapatite (HAp) deposition onto positively charged surfaces (i.e., self‐assembled monolayers (SAMs) terminated with NH 2 head groups) and negatively charged surfaces (i.e., OH‐SAMs (weak) and COOH‐SAMs (strong)) soaked at 50°C in aqueous supersaturated solutions (1.5 SBF, pH 7.0–7.6; SBF = simulated body fluid) w…
Abstract The direct enzymatic polymerization of miniemulsions consisting of lactone nanodroplets represents a new and convenient pathway for the synthesis of biodegradable polymer nanoparticles, where the chemical composition and molecular weight can be varied in a certain range. Oligoesters completely end‐capped with…
The temperature-dependent frequency shift of resonant Raman spectra of double-wall carbon nanotubes is investigated in the range of 78–650 K. We show here that different radial breathing mode (RBM) peaks, which are relative to different tube diameters, have a different temperature coefficient of frequency shift, and t…
The attachment of fibrinogen, bovine serum albumin, and immunoglobulin on continuous wave (CW) and pulsed plasma polymerized di(ethylene glycol) monovinyl ether was studied using surface plasmon resonance (SPR) spectroscopy and waveguide mode spectroscopy (WaMS). Structural analysis of the films was carried out using…
This paper deals with a study on an iron loss analysis method in the single-phase line-start permanent magnet synchronous motor. The iron loss is affected by the time rate of the change of magnetic flux density at the motor cores. The distribution and changes in magnetic flux densities of the motor are computed by usi…
Four series of new [1]benzothieno[3,2- b][1]benzothiophene derivatives have been synthesized. In the non-chiral series a SmA phase occurs, while the chiral series exhibits a rather wide antiferroelectric SmCA* phase just below the SmA phase. The SmA-SmCA* phase transition has been studied using DSC and dielectric spec…
The spectroscopic properties of erbium-doped silicon dioxide, bismuth oxide, and sodium oxide glasses are investigated based on Judd–Ofelt analysis for absorption spectra, bandwidth analysis for emission spectra, and lifetime measurements of the 4I13/2 level of Er3+. The effects of bismuth oxide on these three optical…
The plasma proteins adsorbing onto intravenously injected carriers are considered to be crucial factors determining the organ distribution. Plasma protein adsorption patterns were analyzed on solid lipid nanoparticles (SLN) stabilized with Tween 80 or stabilized with poloxamer 188. The binding patterns were determined…
The oil-degrading microorganism Acinetobacter venetianus RAG-1 produces an extracellular polyanionic, heteropolysaccharide bioemulsifier termed emulsan. Emulsan forms and stabilizes oil-water emulsions with a variety of hydrophobic substrates. Removal of the protein fraction yields a product, apoemulsan, which exhibit…
Silicon carbide (SiC) and diamond were decomposed to CO(2)(g) by the photocatalysis with TiO(2) at room temperature, although the decomposition rate of diamond was very slow. According to the XPS spectra of Si2p on the SiC surface, SiO(2) was simultaneously formed on the surface by the TiO(2) photocatalysis. The thick…
On the basis of literature ab initio data, we show that diamond nanorods would have a brittle fracture force and a zero strain stiffness that exceeds carbon nanotubes for radii greater than about 1−3 nm, depending on the orientation of the diamond nanorod. The energetic stability of diamond nanorods is predicted by mo…
Functionalized branched polysiloxanes with star-branched, comb-branched and dendritic-branched topologies were synthesized. The branched macromolecules were generated by coupling of reactive blocks using a grafting technique ( ACS Polym. Prepr. 2001, 42, 227; ACS Symp. Ser. 2003, 838, Chapter 2). The living anionic ri…
Abstract Low‐density polyethylene (LDPE) was functionalized by melt radical grafting with glycidyl methacrylate (GMA) and employed for reactive blending with polyamide‐6 (PA6). The effect of the reaction procedure on the grafting degree of LDPE‐ g ‐GMA samples (0.5–12.5 wt.‐% GMA) was analyzed as a function of the con…
A method is developed to take the eddy currents in lamination stacks into account with the finite-element method using the three-dimensional (3-D) magnetic vector potential magnetodynamic formulation. It consists in converting the stacked laminations into continuums with which terms are associated for considering the…
ABSTRACT: The aim of this work is to develop a mathematical model to predict the lysozyme release kinetics from crosslinked polyvinylalcohol (PVOH) into an aqueous solution. The model was developed by taking into account both the diffusion of water molecules into the polymeric film and the counter‐diffusion of the inc…
