We study how the dye dispersion influences the properties of ferroelectric liquid crystal (FLC). The polarisation measurement shows the decreasing linear behaviour with the increasing concentration of dye, indicating the orientation of dye in a direction opposite to FLC molecules. Accordingly, the response time increa…
In this paper, we developed an optical model describing the behavior of light at the surface of a slanted lenticular array for autostereoscopic displays in three dimensions and simulated the optical characteristics of autostereoscopic displays using the Monte Carlo method under actual design conditions. The behavior o…
We have measured the low-field magnetoresistances of a series of Sn-doped indium oxide thick films in the temperature T range of 4-35 K.The electron dephasing rate 1/τϕ as a function of T for each film was extracted by comparing the magnetoresistance data with the threedimensional weak-localization theoretical predict…
Smart material electrohydrostatic actuator based on giant magnetostrictive transducer can meet the requirements of smaller vehicles like the unmanned combat air vehicle as well as in rotating environments like helicopter rotors. In order to analyze and improve the performance of smart material electrohydrostatic actua…
Preparation of functionalized graphene by electrochemical exfoliation of graphite rod using sodium dodecyl benzene sulfonate (SDBS) is reported. SDBS solution has been used as the electrolyte as well as functional groups. SDBD is an anionic surfactant which helps to provide uniform dispersion in water and prevents the…
Tm(3+)/Tb(3+)/Eu(3+) tri-doped phosphate glasses are synthesized to explore new white-light-emitting materials. Under 365 nm excitation, the CIE coordinates (x=0.339, y=0.341) of the Eu0.07 glass sample are close to the standard equal energy white-light illumination (x=0.333, y=0.333). The quantum efficiency is very h…
Anti-bacterial and biodegradation activities of Poly (lactic acid) (PLA) and wood flour/PLA composites (WPLA) were investigated for the effect of anti-bacterial agent addition. Silver substituted Zeolite (commercially designated as Zeomic) was used as anti-bacterial agent in this study. Anti-bacterial activities were…
The first wall of a magnetic fusion power reactor is defined essentially as the plasma-facing walls of blankets. For the high temperature operation of self-cooled breeder blankets, the first wall is often designed to be less than 1cm thick to reduce mechanical stresses and as a result will be subjected to bi-direction…

A gold solidus of Valentinian I, Emperor of Rome (A.D. 364-375) shown in Figure 1, and belonging to a private collection, was subjected to material and stylistic analysis, in order to ascertain about its authenticity. Due to the rarity of such a coin, only non-destructive analytical techniques were used, namely Scanni…
Engineered nanomaterials such as nanoparticles (NPs) are increasingly being used for commercial purposes in products within medicine, electronics, sporting goods, tires, textiles and cosmetics. They comprise diverse types of materials from metals, polymers, ceramic to biomaterials and have been defined as particles wi…
Ultra stable Y type(USY) zeolite and HUSY zeolite were applied to catalytic cracking of wood-plastic composite(WPC) fast pyrolysis vapors using analytical pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). Compared with the results of non-catalytic pyrolysis, there was a dramatic increase in the concentration…
The chemical composition of a 960 Mpa grade high strength steel with low carbon equivalent was designed. Effect of direct quenching and tempering process on the microstructure and mechanical properties of the experimental steel was studied. Results showed that fine lath martensite was obtained after controlled rolling…
The FePt (30 nm)/NiO (2 nm) bilayer films with or without an intermediate layer were deposited on Si substrate at ambient temperature by magnetron sputtering. The films were then post-annealed at 700 °C for 3 min by Rapid Thermal Annealing (RTA) with a high heating ramp rate of 100 °C/sec. The perpendicular coercivity…
Yttrium complexation in extraction systems with benzoic acid (BA) and tris(hydroxymethyl)aminomethane (THMAM) was studied. The growth of yttrium distribution ratios in this system is caused by the formation of different-ligand coordination compounds of yttrium with BA and THMAM. Quantum chemical calculations for the f…
Nowadays, the combination effects of thermal, mechanical and electrical on the reliability issues of solder joint gain more and more attentions. The independent failure mechanisms of solder joints are widely investigated and comprehended under single conditions as listed above. However, the coupling effect of thermal,…
Abstract Dicke, eigenspannungsarme, kubische Bornitridschichten können heute mit maßgeschneiderten Schichtkonzepten mit allen PVD‐ und PECVD‐Verfahren hergestellt werden. Dies lässt sich dadurch erreichen, dass man neben Bor und Stickstoff ein geeignetes drittes Element in der richtigen Konzentration in die Schicht ei…

Study the reaction of sodium hydroxide with silica from corn straw ash (CSA). The influences of concentration of sodium hydroxide solution, the ratio of CSA mass to sodium hydroxide solution volume, reaction time, and reaction temperature for the dissolution rate of silica and the sodium silicate modulus are studied.…
Tensile specimens with a Cu/IMC/solder/IMC/Cu structure were prepared, and were treated by 0h, 72h, 168h, 288h, 500h, 1000h isothermal aging processing at 150°C. Quasi-static tensile tests were conducted on the micro-tester Instron5948, Fracture analysis of fractured specimens was conducted by optical microscopy and s…
