The wide application of pressure sensitive adhesives (PSAs) in thin film transistor liquid crystal display (TFT-LCD) devices is based on their advantages that PSAs provide sufficient bond strength and also are cleanly removable upon debonding. These two essential requirements are not obtainable without a proper unders…
The effects of resin blend or solvents on a deposited film in an electropaint system were studied. We confirmed that the film formation follows the ion-permeable film formation (IPFF) model. The film resistivity fell off after the addition of a resin with a low glass transition temperature ( T g ) to a resin with a hi…
The plasma plume generated during laser ablation of a carbon target (graphite 99.99%), is characterized by means of Optical Emission Spectroscopy (OES) and the Langmuir probe technique. Both techniques allow the determination of the mean kinetic energy of ions present in the plasma. Besides that, information about the…
The adsorption behavior of benzoic acid onto a water-compatible hypercrosslinked polymeric adsorbent NJ-8 was compared with that onto macroporous Amberlite XAD-4. This paper focuses on the static equilibrium adsorption behaviors,the adsorption thermodynamics and the column dynamic adsorption profiles. Five isotherm mo…

Vibrational spectroscopy enables subtle details of the molecular structure of minyulite KAl2(OH,F)(PO4)2⋅4(H2O). Single crystals of a pure phase from a Brazilian pegmatite were used. Minyulite belongs to the orthorhombic crystal system. This indicates that it has three axes of unequal length, yet all are perpendicular…
The numerical model of columnar to equiaxed transition (CET) was constructed with consideration of molten steel flow. Solid shell growth was analyzed by using macroscopic heat flow model in addition to heat transfer due to the fluid flow at the solidification front, which was calculated by fluid flow model. At the sam…
This review is focussed on the crosslink distributions between rubber phases, which arise when blends of rubbers are vulcanized, how these distributions may be evaluated and controlled, and how they impact upon the properties of the blends. The blends are divided into three categories - rubbers differing primarily in…
This study has certified that investigating the characteristics of mic romorphology of Neogene red clay is also one of the effective methods to analyze the paleoclimate, and correlate and subdivide the strata. According to the ch aracteristics of micromorphology of Neogene red clay developed at Xiaqiang Villa ge, Xuny…
Measurement of the X-ray diffraction patterns of 304L stainless steel after subjecting it to an electrochemically induced surface annealing process in concentrated nitrite solutions shows that the austenite lattice contracts during processing relative to the untreated alloy. The surface annealing procedure, which invo…
We have studied the influence of multiple carbon treatments on the properties of silica porous glasses. Each step of each carbon treatment started with filling the voids of porous glass with carbon. During the following anneal carbon interacted with the walls of the voids. It was shown that low dimensional silicon clu…
We present the first computer simulation study of the Freedericksz transition in a nematic phase using a Gay-Berne model mesogen, in which the constituent molecules can both rotate and translate freely. The behaviour and structure of the nematic obtained from the simulation for the Freedericksz transition are compared…
—As the applications of composite structures have increased, various techniques to join composite parts to the structures have been developed in order to meet the required adhesion strength. In this work, surface modification of carbon/epoxy composites was investigated using ultraviolet (UV) surface treatment to incre…
Structural and thermal characterizations and dc resistivity measurements were performed for polyvinyl acetate (PVAc)/polyvinylidene fluoride (PVDF) blends. The ferro- to para- electric transition temperature ( T FP ) and the melting temperature of PVDF were detected by DTA. X-ray diffraction and infrared analysis evid…
The thermal stability of gold deposited on Nb 2 O 5 /W, Nb 2 O 5 /Nb and NbO/Nb substrates was investigated by angle-resolved X-ray photoelectron spectroscopy. Gold in amounts 0.1-1.2 monolayer was vapour-deposited on an oxide substrate under ultrahigh vacuum. A shift of the Au (4f) core level towards higher binding e…
Fiber bundles in sliver form more closely represent the fiber bundles commonly used in commercial testing.Therefore, this experiment focused on studying drafting force using untwisted fiber bundles (sliver) rather than twisted fiberbundles (roving) as had been previously studied. Four cottons of similar micronaire but…
In ferromagnetic martensite of some Ni-Mn-Ga alloys, magnetic field causes movement of twin boundaries, which results in large magnetic-field-induced strain. Present work is a review of some original experimental results concerning in-situ studies of the correspondence of magnetic domains with twin domains and their r…
Thema des Buches ist eines der umfangreichsten Industrieprojekte in der Geschichte der Schweiz: Die Entwicklung eines eigenen Reaktortyps. Während eines Jahrzehnts bemühten sich zahlreiche Industriefirmen, Bundesstellen, wissenschaftliche Institute und Elektrizitätsgesellschaften, den Anschluss der Schweiz ans Atomzei…
The use of advanced lightweight materials to improve combat survivability has been of crucial interest to the U.S. Army for a number of years. Specifically, hybrid organic/inorganic polymer matrix nanocomposites show promise in providing many of the physical properties required (i.e., lightweight structure, rugged abr…
The synthesis and surfactant activities of two new cationic gemini surfactants containingtriazole compound as spacer were described. Their critical micelle concentrations (CMC), whichare 1.8 × l0-4 mol/L and 3.9× 10-4 mol/L respectively, are much lower than that of conventionalsurfactant cetyltrimethyl ammonium chlori…
