Appearance of a residual image of the previous frame at liquid crystal display due to change of the interface between LC and aligning layers is called as sticking effect. Phenomenologically sticking effect can be associated with changes of direction of easy axis, e r , and anchoring energy, W, during the action of the…
The fracture characteristics of the joint were analyzed by means of scanning electron microscope(SEM).Microstructures of the joint were examined by means of optical microscope, SEM and an image analyzer. The results show that the tensile strength of the inhomogeneous joint of TiNi shape memory alloy and stainless stee…
We have produced Sm2(Fe, Mn)17Nx coarse powders by a reduction and diffusion (R/D) method and investigated the characteristics. The Sm2(Fe, Mn)17 mother alloy powder made by the R/D method showed rounded shape and sharp particle size distribution, and was consisting of almost only Th2Zn17-type phase with minor α-Fe. F…
Instrumental characterization of an adhesion interface in a rubber-brass system often faces a difficulty in exposing the clean surface due to the stick of the rubber residue on the brass surface. We have succeeded in isolating the interface from the rubber matrix by inserting a filter paper between rubber and brass du…

Electrical and photoelectrical properties of Al/porous silicon/ monocrystalline silicon sandwichstructures (Al/PS-(c-Si)) based on nanostructured porous silicon, obtained by electrochemical anodization of monocrystalline silicon wafers are reported. The photosensitivity of Al/PS-(c-Si) structures is determined by PS l…
Electrochemical impedance spectroscopy (EIS) is a well established technique for evaluating the corrosion preventive properties of protective coatings. National Museum of Australia (NMA) staff have used this technique in the past to evaluate and rank the corrosion performance of a number of commercial waxy coatings in…

The melting behavior of two commereial flint and amber glass batches with varied cullet content (0, 40, 65 % and 0, 40, 76 %, respectively) and batch water additions (0 to 5 %) was investigated. The cullet was a blend of up to five industrial types and grades, including ground cullet. Local temperature, electrical con…
Grossular (Grs 99 Adr 01 ) crystals were synthesized in hydrothermal experiments by the reaction wollastonite + calcite + anorthite = grossular + CO 2 (400 MPa; 695-750 °C; X CO₂ = 0.1; solid:fluid = 2:1) using natural minerals as starting materials. Growth spirals are visible due to silica decorations. The crystals a…
As-cast melt extracted CoFeSiBNb wires 37.5 µm in average diameter prepared by MXT Inc. of Montréal have a predominantly helical anisotropy due to residual tensile and torsional stresses quenched in during preparation. When a supplementary tensile stress is applied along the wire, its easy axis of magnetization rotate…
The effect of carbon nanotubes on the thermal decomposition of CL-20 is studied by means of DSD and TG. The results show that the addition of carbon nanotubes makes the onset temperature and peak temperature of DSC curve shift downwards, the value of activation energy thermal decomposition of CL-20 decrease from 184.3…
Using mimosa tannin as vegetable tanning agent and oxazolidine as aldehydic tanning agent,the effects of hydrogen bond,hydrophobic bond and side amino group of collagen on vegetable tanning,aldehyde tanning and vegetable-aldehyde combination tanning were investigated.Results indicated that aldehyde predominantly react…
The heat transfer performance and pressure drop of 3 different tubes under different ultrasonic power are experimentally investigated using a tube-shell heat exchanger model and the designed ultrasonic vibration device. The results show that the heat transfer coefficient increases obviously while the pressure drop dec…
By introducing an anisotropic factor in the cell dynamics of constant pressure molecular dynamics simulations, we dramatically reduce the artifacts related to cell shapes and overcome the difficulties of simulating anisotropic molecules under hydrostatic pressure. The method is especially effective for anisotropic liq…
ening, stiffening and water repellent agents have been employed. In this work, a mixture of dimethylol dihydroxy ethylene urea (DMDHEU), polyvinyl acetate (PVAc) and some other resins were examined in special finishing of cotton for producing interlining cotton fabrics properties. Majority of cross-linking agents used…
Thermal resistivity data are reported for loose-fill cellulose manufactured in Korea and the United States over the temperature range 40 to 100 F. A representative thickness of 1.1 in. for thermal test specimens was determined for cellulose insulation in the density range that was studied. Measurements for insulations…
Ba(2)CoS(3) is the first example of an inorganic solid containing one-dimensional corner-sharing [Co(2+)-anion] chains, which leads to one-dimensional cooperative antiferromagnetism.
We present the results of investigations into the utilisation of polymeric waste arising in the manufacture of polyester fibres. Polyethylene terephthalate waste of various molecu lar weights (Mv ≅ 13500 and 18000) was glycolysed under different conditions including varying the PET/EG proportion, temperature and time…
