Effect of β-Glucans and Process Conditions on the Membrane Filtration Performance of Beer
An extended filtration test with 0.45-μm membranes was employed in this study to investigate the influence of β-glucan polymers, shearing, pH, ethanol content, and storage time on beer filterability. Results indicated that the presence of β-glucans caused lower beer filterability. The maximum amount of beer filtered t…
On the Role of Characterization in the Design of Interfaces in Nanoscale Materials Technology
This work reviews recent research on the design and control of interfaces in engineering nanomaterials. Four case studies are presented that demonstrate the power of a multimodal approach to the characterization of different types of interfaces. We have used a combination of conventional, high resolution, and analytic…
TUNING THE EXCITED STATES IN fac-[Re(X2dppz)(CO)3(L)]: INTRALIGAND, CHARGE TRANSFER OR BOTH?
Excited state lifetime measurements - emission, emission lifetime and Resonance Raman - have been conducted on the series -fac--[Re(X2dppz)(CO)3(L)]0,+ (L = Cl-, 4-ethylpyridine (4-Etpy), 4,4´-bipyridine (4,4´-bpy)), with the X2dppz substituted dipyrido[3,2-a:2',3'-c]phenazine ligands (X = CH3 and Cl). The results are…
SrFeO 3 nanoparticles-dispersed SrMoO4 insulating thin films deposited from Sr2FeMoO6 target in oxygen atmosphere
Dielectric SrMoO4 thin films were deposited from Sr2FeMoO6 target in oxygen atmosphere, showing obvious M–H hysteresis loops at room temperature. It was revealed by transmission electron microscopy that SrFeO3 nanoparticles are dispersed in the SrMoO4 grains, to which the hystersis loops of the thin films are ascribed…
Effect of Endgrain Attack on Corrosion of 18Cr-10Ni Austenitic Stainless Steel in Simulated Dissolver Liquor
The exposed endgrain of austenitic stainless steels displays significantly inferior corrosion resistance toward the rolling direction in nitric acid solutions. Endgrain attack is often accompanied by preferential localised corrosion which produces features similar to pitting corrosion. From the viewpoint of average co…
Anti-rejection effect of ethanol extract of Poria cocos wolf in rats after cardiac allograft implantation.
BACKGROUND: A living fetus within the maternal uterus provides an example of allogene tolerance in mammals. Poria cocos Wolf is the main component of many Chinese medicinal combination drugs that have therapeutic effects on recurrent spontaneous abortion and that can maintain pregnancy until delivery. It was hypothesi…
On the determination of the volume fraction of Ni4Ti3precipitates in binary Ni-rich NiTi shape memory alloys
Abstract The size distributions and volume fractions of Ni4Ti3 precipitates in Ni-rich Ni–Ti shape memory alloys affect their mechanical and functional properties. In the present work precipitate sizes and volume fractions were measured after various thermo-mechanical treatments using transmission electron microscopy…

MOCVD of LaAlO3 Films from a Molten Precursor Mixture: Characterization of Liquid, Gas, and Deposited Phases
Abstract The capability of “second‐generation” precursors to act as a solvent of other precursor species, thus yielding a molten multi‐component source, has been investigated in detail. In particular, this novel approach has been applied to the MOCVD process of high quality, epitaxial LaAlO 3 thin films on SrTiO 3 (10…
Characterisation of a phenolic resin and sugar cane pulp composite
Polymeric materials are increasingly replacing metallic materials as a result of their properties. In this work a composite of phenolic resin and sugar cane pulp was developed. The sugar cane pulp has been previously alkalinised, dried, and milled and the particles had been classified in a range of grain sizes. Experi…
Synthesis, Spectral Properties, and Antitumor Activity of a New Axially Substituted Phthalocyanine Complex of Zirconium(IV) with Citric Acid
The new axially substituted phthalocyanine (pc) complex of zirconium(IV) with citric acid is reported. It has been shown that the replacement of two Cl-atoms with two citric acid fragments takes place as the result of the reaction between [ZrCl2(pc)] and citric acid. The complex [Zr(citrate)2(pc)] was formed. The spec…
Effect of Climatic Parameters on Filiform Corrosion of Coated Aluminum Alloys
The effects of temperature, relative humidity, and wet-dry transition on initiation and propagation of filiform corrosion on coated aluminum alloy 6016 (AA6016 [UNS A96016]) have been studied. Corrosion products formed in the filament were analyzed using Fourier transform infrared (FTIR)-microspectroscopy. The aluminu…
Main Directions and Recent Test Modeling Results of Lithium Capillary-Pore Systems as Plasma Facing Components
At present the most promising principal solution of the divertor problem appears to be the use of liquid metals and primarily of lithium Capillary-Pore Systems (CPS) as of plasma facing materials. A solid CPS filled with liquid lithium will have a high resistance to surface and volume damage because of neutron radiati…
Fotoluminescência em materiais com desordem estrutural
A grande maioria dos estudos fotoluminescentes foram realizados com materiais cristalinos, cuja emissão ocorre em temperaturas criogênicas, limitando a aplicação destes materiais. Por sua vez, determinados sólidos com alta densidade de defeitos (amorfos), como titanatos, tungstatos, zirconatos, entre outros, apresenta…
Silk Production after Mechanical Pulling Stimulation in the Ampullate Silk Glands of the Barn Spider, Araneus cavaticus
ABSTRACT Synthesis of protein by the major ampullate silk glands in the barn spider, Araneus cavaticus was stimulated by depleting the storage of silk protein in the ampulla by mechanically pulling fiber from the spigot. After this treatment, fine structural changes of the glandular epithelium during silk production w…
Precise Control of Nanowire Formation Based on Polysilane for Photoelectronic Device Application
A High-energy single ion trajectory in a Si-based polymer thin film produces a cross-linked polymer nanowire with the length of 10–1000 nm and the thickness of 4.0–19.4 nm (radius of the cross section). The energy density deposited by incident ions and the molecular weight of the target polymer materials principally d…
Decomposição catalítica de óxidos de nitrogênio
<abstract language="eng">Contaminant gases in the atmosphere constitute an important problem to be solved in the world. The NOx gases produced as a consequence of engine high temperatures are deleterious to environment and human health, as they promote acid rain and can act in the same way as freons in the destruction…

This study examined the illuviation of clay and spodic materials in three Ultic Haplorthods derived from fine-textured materials from the Alishan Mountain of central Taiwan. Soil analysis, including field description, physical and chemical analyses, and micromorphological studies, was used to study the soils. The soil…
Inhibition of steel and galvanised steel corrosion by zinc and calcium ions in the presence of phosphate
Mixtures of zinc, calcium and phosphate ions have been found to be effective (>90%) in inhibiting the corrosion of steel and zinc during immersion in acid rain solution and when used as pigment additions to organic coatings. The presence of calcium ions, in addition to zinc ions, appears to be fundamental in the inhib…
