Hot corrosion of layered machinable ceramic coated with in air at 700-1000°C has been investigated by means of thermogravimetric analysis, X-ray diffraction, Raman spectroscopy, and scanning electron microscopy/energy-dispersive spectroscopy. The hot corrosion of was slight at low temperatures of 700 and 800°C, while…
The formation characteristics of the vertical density profile of MDF are presented herein. Results of laboratory studies indicate that the vertical density profile of MDF is formed from a combination of actions that occur both during compaction and also after the press has reached final position. The methodology, whic…
Dielectric properties of silica filled silicone rubber used for high voltage insulation are studied as a function of frequency (1 mHz - 1 MHz) and temperature 213K - 433K.. Two different polarization mechanisms are identified. The frequency dependence of the dielectric constant and loss factor is well characterised by…
Hydrogen reaction on catalytic surfaces is an important field of research in fuel cell science. The adsorption of hydrogen (deuterium) on Co(0001) and the influence of carbon monoxide and sulphur on the adsorption were studied by XPS, TDS, WF measurements and LEED. The WF increased due to D2 adsorption, revealing the…
Remote-oxyfunctionalization induced by 2,6-dichloropyridine N-oxide (DCP N-oxide) as an oxygen donor and a (5,10,15,20-tetramesitylporphyrinate) ruthenium(II) carbonyl complex (Ru-porphyrin) and HBr as catalysts was examined for a series of methyl ester-peracetylated derivatives of (5 beta)-3-oxobile acids. Using the…
Abstract This International Standard specifies two methods for determining the maximum count rate for an acceptable limit of divergence from linearity of the intensity scale of Auger and x‐ray photoelectron spectrometers. It also includes methods to correct for intensity non‐linearities so that a higher maximum count…
Different approaches to the description of the structure of intermediate chiral smectic C* phases are discussed and the concept of the “discrete” flexoelectric effect is introduced that describes a polarization induced in a smectic layer by a difference in director orientation in the two other layers adjacent to it. I…
Experiments were carried out to investigate in-situ reactions of refractory and its interactions with slag (composition: 45.4%SiO2+36.6%CaO+15.9%Al2O3) using a horizontal furnace by detecting CO and CO2 contents in off gas with an infrared (IR) analyzer. The composition of refractory is 69.4%Al2O3+7.3%SiO2+10.6%SiC+12…
We report on Raman scattering of VO 2 films prepared by radio frequency magnetron sputtering under different conditions. Our investigations revealed that the dominated Raman peaks shift towards high frequency for both V-rich and O-rich VO 2 films, compared with the stoichiometry VO 2 films. The experimental evidence i…
Highly ordered mesoporous materials constructed with integrated polymer-silica hybrid frameworks can be obtained via a one-step synthetic strategy using a mixture of polymer and silicate as the framework sources in the presence of a structure-directing agent.
An ordered structure of [OsL(3)](2+)(L = 2, 2'-bipyridine or 1, 10-phenanthroline) layer in an ultrathin film composed of the complex cations, clay nanosheets and alkylammonium cations is reported on the basis of its in-plane X-ray diffraction and polarized electronic spectral data.
One of the objectives of the European SUBZERO project was to study the influence of sweat evaporation and condensation on the heat transmission properties of cold protective clothing. With the sweating thermal manikin Coppelius, water vapour transfer through and water condensation in the clothing can be determined sim…
Conventional methods employed in leather processing subject the skin or hide to a wide variety of chemicals. This contributes to an increase in COD, TDS, chlorides, sulfates and other mineral salts in tannery effluent. A process sequence has now been explored viz., enzymatic dehairing, enzymatic fiber opening, and pic…
Solid oxide fuel cells (SOFCs) convert chemical energy in the reaction materials to electrical energy directly, and are characterized by their high effeciency, cleanliness, all-solid structure, and high temperature operation.This new technology is one of the fastest developing forms of energy source, and may well be a…
Through inspections of Japanese boiling water reactors (BWRs) from 2002, a high occurrence rate of Inter Granular Stress Corrosion Cracking (IGSCC) was confirmed in core shrouds and re-circulation (PLR) pipings made of low-carbon (L-grade) stainless steels (Okamura, et al., 2003), and the evaluation of IGSCC growth be…
Technologies currently used for cotton contaminant assessment suffer from some fundamental limitations. These limitations result in the misassessment of the cotton quality, and have a serious impact on its economic value. Through our research, we have shown that X-ray microtomographic image analysis may be applied wit…
Hydrogen distribution in high-purity-based polycrystalline Al-5%Mg alloys prepared by changing the melting atmosphere was visualized by means of hydrogen microprint technique with electron backscattering pattern analysis after a tensile deformation at room temperature. The number of hydrogen atoms observed as silver p…
Progress in the processing of wet tissues, without the need of fixation and complex preparation procedures, may facilitate the microscopic examination of tissues and cells. Microscopic examination of tissues is a central tool in clinical diagnosis as well as in diverse areas of research. The authors present the applic…
Monolayer protected nanoparticles, Au@ZrO2@stearate and Ag@ZrO2@stearate, in which the core–shell nanoparticles, Au@ZrO2 and Ag@ZrO2 (ZrO2 coated Au and Ag nanoparticles) are functionalized with stearic acid, have been synthesized and characterized. The air-dried powders, freely dispersible in several organic solvents…
Magnetite nanocrystals, which are normally formed by magnetogeneric bacteria, have been prepared using a single source metallorganic precursor.
