Planetary Pipe rolling process for AISI 304 stainless steel has been studied by using finite element method. Three-roll Mannesmann method is applied to this study. Commonly, rolling process has started from the cold working and finished to the hot one. The rolling process can provide excellent combinations of cost and…
The control of phase plays a fundamental role in wave propagation. Metasurfaces (thin metamaterial layers) can introduce an additional spatially non-uniform phase in the incoming wave, thereby affecting its propagating characteristics. A metasurface consisting a plasmonic nano-antenna array can introduce an abrupt pha…
Discontinuous changes in density (Δρ) at various phase transitions in an antiferroelectric liquid crystal, 4-(1-methylheptyloxycalbonyl)phenyl 4'-octyloxybiphenyl-4-carboxylate (MHPOBC), were estimated using published data and the Clausius–Clapeyron equation. The estimated Δρ at the SmCFI1 *–SmC* transition is about t…
A gold/silicon Schottky-type plasmonic detector was monolithically integrated with two metal-oxide-semiconductor field-effect transistors (MOSFETs) on a silicon substrate. The output current from the detector was amplified 14000 times by using the MOSFETs.
In this paper 110 female undergraduates in Soochow University are measured by using 3D non-contact measurement system and manual measurement. 3D point cloud data of human body is taken as research objects by using anti-engineering software, and secondary development of point cloud data is done on the basis of optimizi…
This paper discussed the effect of different composition ratio of Iodine doped multiwalled carbon nanotubes (I-MWCNTs) in MEH-PPV for organic solar cell applications. The I-MWCNTs compositions were varied from 0, 30, 50, 60 and 80 wt% and the effect to the electrical, optical and physical properties were investigated.…
The development of CdTe/CdS solar cells on flexible substrates is reviewed in this article. Photovoltaic structures on lightweight and flexible substrates have several advantages over the heavy glass based structures in both terrestrial and space applications. The cells mounted on flexible foil are not fragile, the re…
Leaching and adsorption of copper complexes simultaneously occur in ammoniacal thiosulphate resin-solution systems. The reaction requires good control-independent variables to minimize reagent consumption as well as to obtain optimal adsorption of copper complexes on resin. This work proposed the development of a mech…
Fabric, our second skin with moisture and thermal capacity for skin temperature regulation, can arouse feelings of pleasant and discomfort. To examine the neurocognitive ability and emotion of fabric tactile perception under different local temperatures, we used functional magnetic resonance imaging with the same deni…
Circularly polarized optical second harmonic generation (SHG) is studied experimentally in regular arrays of planar G-shaped nanostructures. Circular dichroism in SHG is observed and the sign of the effect reverses with the handedness of the nanostructures, which is a signature of chirality in the nonlinear optical re…
With rising demands, oil and gas exploration of high-pressure high-temperature (HPHT) wells are increasing worldwide. Due to aggressiveness of HPHT environments, piping and equipments are constructed with high-strength corrosion resistant alloys (CRAs). Duplex stainless steel is one of the candidate alloys that offer…
Emission spectrum of Iridium complex bis [2-(9, 9-diethylfluoren-2-yl)-5-trifluoromethyl-pyridinto-C3, iridium (acetylacetonate) (fl-5CF3-py)2Ir (acac) in THF was 589 nm. Two weak UV absorption bands can be assigned to spin-allowed singlet metal-to-ligand charge transfer (1MLCT) and spin-forbidden 3MLCT transitions. T…
Self-assembly behavior of an cationic amphiphilic triblock copolymer Q-PVBC -b-PS-b-Q-PVBC in DMF/water and DMF/methanol were studied. Well defined triblock copolymer PVBC-b-PS-b-PVBC was synthesized by RAFT polymerization and the cationic amphiphilic block copolymers Q-PVBC-b-PS-b-Q-PVBC was obtained by the quaterniz…
This paper selected 10 kinds of fabrics of thermal underwear, which are the representatives on the market; carried out tests on the fabric properties (thickness, density, the gram per square meter, etc.) and the fabric wearability (permeability, water vapor permeability, wicking height, insulation and antistatic prope…
To provide polypropylene (PP) with better excellent mechanical properties, nanoCaCO3 particles are incorporated into PP matrix by melt blending in this work. To improve the mophology between PP and nanoCaCO3, maleic-anhydride grafted PP (PP-g-MAH) was added as a compatibiliser. The results showed that PP-g-MAH indeed…
The power transmission steel structures are used in the outdoor and the durability will be decreased due to the various corrosions, so the structures usually coated the anti-corrosion layers such as hot-dip coating, zinc-rich coating or thermal spray zinc coating. The anti-corrosion layers on three power transmission…
A kind of environment-friendly Cr-free insulating coating for grain-oriented electrical steel is exhibited in this paper. The tensile stress and the magnetic properties for both Cr-free and Cr-containing insulating coating were measured. The results showed that the more the coating on the metal, the bigger the tensile…
To explore environmentally benign method for preparing TiO2, composite photocatalysts TiO2 immobilized on activated carbon fibers (TiO2/ACF) were prepared in caprolactam tetrabutyl ammonium bromide ionic liquid (CPL-TBAB ILs). The TiO2/ACF composites were characterized by X-ray diffraction (XRD) and scanning electron…
The testing of the blend ratio of cashmere/wool yarns is mainly depended on human-powered. It introduced the colors divergence of two fibers using HI-1 dye to stain into the blend yarn of wool and cashmere. The colored samples were then, sliced and imaged. Both the cashmere and wool that have some color information we…
Zinc oxide (ZnO) is one of the metal oxide semiconductors suitable for use in optoelectronic devices and a potential material for the future solar cell applications. In this works, ZnO films were deposited on silicon and glass substrate by reactive rf magnetron sputtering using a solid Zn target. The influence of the…
