The effect of holes on the band formation and the serrated deformation in planar specimens of aluminum–magnesium alloys AlMg5 and AlMg6 is studied by high-speed video filming of moving deformation bands. It is found that the concentration of an elastic field near a hole causes early nucleation of macrolocalized deform…

The in-plane strain fields of single-vacancy silicene with different monovacancy (MV) concentrations, as well as the corresponding electronic band structures, are investigated by using the first-principle calculations. Firstly the self-healing MV is found to be the most stable ground structure in silicene, which is di…
Nanoparticles of Eu3+ doped YPO4 have been prepared by co-precipitation method. The structure, morphology, composition and photoluminescence were characterized by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), IR Spectroscopy, and Scanning electron microscopy (SEM) and Photoluminescence spectrosc…
Marine biomass resources are abundant and have a variety of functional groups, whose development prospect should be considerable. Tunicate is a kind of sea animal who can produce cellulose that was mainly composed of nanofibers. This review briefly introduced the progress in the architecture of tunicate cellulose and…
Cyclic thermal analysis is used to study the effect of overheating of the eutectic Ga–8.5 mol % Sn melt on the presolidification supercooling. It is found that, when the liquid eutectic is overheated above the eutectic temperature (T e = 293.5 K) and is subsequently cooled, the dependence of the presolidification supe…
Zinc Sulfide nanostructure was successfully deposited on glass substrates by spray pyrolysis method.
Radiative properties and spectroscopic studies of several Nd 3+ doped Borate glass system have been reported. Judd-Ofelt intensity parameter and other parameters like oscillator strength ( f ), effective bandwidth (D l eff ), radiative transition probabilities (A R ), stimulated emission cross section (s), branching r…
A combined high-resolution Co K -edge extended x-ray absorption fine structure (EXAFS) and high-resolution X-ray powder diffraction (XRD) study has been performed to clarify the detail of anomalous behavior of temperature-dependent magnetic susceptibility curve on the LaCoO 3 across the spin-state (∼120 K) transition.…
A novel form of anhydrous dicalcium phosphate CaHPO4 (monetite) is synthesized hydrothermally and characterized by single crystal X-ray diffraction. It crystallizes in the orthorhombic space group Ccm21 with a = 6.242(1) Å, b = 6.994(2) Å, c = 7.003(3) Å, V = 305.73(16) Å3 and it has four independent unit formulas in…
We demonstrate the first steps towards realizing a highly effective hardmask fabrication technique for producing cheap low defect nanoporous membranes, which can be incorporated as fluidic wicking structures for use in evaporative cooling solutions integrated at device level. Next-generation cooling solutions are beco…
This study proposes a design of a ternary logic inverter using graphene barristor (GB). To design a multiple-valued logic gate, controlling threshold voltages of the unit device should be easy. We determined that the doping concentration of the graphene can easily control the operation voltage of the GB. To realize an…
We propose a new pixel design which has one slit electrode for 847 ppi resolution. The pixel design facilitates a reduction of disclination area in the pixel and reduction of color mixing. As a result, we have demonstrated a high luminance, small color shift until the 30 degrees view angle and good image quality on 5.…
We report two new liquid crystal mixtures with high clearing point, small visco‐elastic coefficient and low activation energy. With overdriving and undershooting approach, the response time is less than 10ms for FFS LCDs at T=0°C and TN at 20°C. Therefore, these mixtures greatly improve the performances of vehicle dis…
Electronic and optical properties of 2D conducting carbon supracrystals are studied. The band structure is calculated using the tight-binding method. One sample is classified as semimetal, and the remaining samples are classified as narrow-band-gap semiconductors. The optical conductivity of the supracrystalline struc…
Second harmonic generation is studied in structures containing nanoscale layers of transition metal chalcogenides that are two-dimensional semiconductors and deposited on a SiO 2 /Si substrate. The second harmonic generation intensity is calculated with allowance for multibeam interference in layers of dichalcogenide…
In this work we report the potential of nanostructured fibers consisting of nanodiamond particles (NDPs) and fish gelatin (FG) to modulate the mechanical properties of fish gelatin hydrogels, in the aim of developing bioinspired ECM analogues. NDPS-loaded FG fibers were obtained by electrospinning. The biocomposites w…
Europium-doped YVO 4 phosphors have been synthesized using microwave radiation of 700 W power. The uniformity and high rate of microwave heating, as well as “nonthermal” effects of microwave radiation, considerably accelerate the decomposition of precursors and YVO 4 :Eu 3+ synthesis. The europium concentration was va…
AZ31B magnesium alloy was anodized in an alkaline electrolyte containing sodium borate, sodium silicate and sodium citrate. Ammonium metavanadate (NH4VO3) was used as an additive to improve the anti-corrosion ability of anodization film. The anodization film was characterized by X-ray diffraction and scanning electron…
