We proposed a patterned vertical alignment (PVA) mode controlled by a modified surface with ultraviolet (UV) curable reactive mesogen (RM) mixed with vertical alignment material for a liquid crystal display (LCD) with fast response time. In the surface-controlled PVA (SC-PVA) mode, the RM monomers in the alignment lay…
The synthesis of stable, low toxic, multifunctional, and water-soluble quantum dots (QDs) is of crucial importance for nanobiotechnology. An in situ anionic ring-opening polymerization strategy was successfully employed to grow multihydroxyl hyperbranched polyglycerol (HPG) from surfaces of aqueous synthesized QDs dir…
We demonstrate that strong interorbital interaction is very efficient to achieve superconductivity due to magnetic fluctuations in the iron pnictides. Fermi-surface states that are coupled by the antiferromagnetic wave vector are often of different orbital nature, causing pair-hopping interactions between distinct $\t…
Polystyrene/silica (PS/SiO(2)) and poly(styrene-co-methyl methacrylate)/SiO(2) composite latex particles were prepared by surfactant-free emulsion polymerization in the presence of a poly(ethylene glycol) monomethylether methacrylate (PEGMA) macromonomer. The resulting composite particles were stabilized by the negati…
Metallic mirrors will be used as plasma-viewing elements in all optical and laser diagnostic systems in ITER. In the harsh environment of ITER, the performance of mirrors will decrease mainly because of the erosion of their surfaces and deposition of impurities. The deterioration of the optical properties of diagnosti…
Abstract Caged chalcogens : A series of novel, functionalized T n S m cages (T=Ge, Sn; n / m =4:6, 3:4) with terminal COO(H) or COMe groups were synthesized and show further reactivity toward Cu I complexes (an example of which is shown here) and to hydrazines. This led to the generation of functionalized Cu/T/S clust…
We show that efficient photoinduced surface-relief gratings can be inscribed in polymer-azobenzene complexes which are bonded by phenol-pyridine hydrogen bonding. The grating inscription was studied as a function of chromophore concentration and the molecular weight of the host polymer, both of which can be easily tun…
Twinning is one of most prevalent deformation mechanisms in materials. Having established a quantitative theory to predict onset twinning stress ${\ensuremath{\tau}}_{\text{crit}}$ in fcc elemental metals from their generalized planar-fault-energy (GPFE) surface, we exemplify its use in alloys where the Suzuki effect…
Using the ab initio exact muffin-tin orbitals method in combination with the coherent-potential approximation, we have calculated the elastic parameters of ferromagnetic ${\text{Fe}}_{1\ensuremath{-}m}{\text{Mg}}_{m}$ $(0\ensuremath{\le}m\ensuremath{\le}0.1)$ and ${\text{Fe}}_{1\ensuremath{-}c}{\text{Cr}}_{c}$ $(0\ens…
Nanocrystalline Ce 1− x Ru x O 2−δ ( x =0.05 and 0.10) of 8−10 nm sizes have been synthesized by hydrothermal method using melamine as complexing agent. Compounds have been characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and energy-disper…
Boron nitride nanofibers (BNNFs) with alignment and large length have been prepared on a large scale by electrospinning the precursor fibers and subsequent nitridation. A multijet/multicollector electrospinning system is constructed by simply arranging three jets and three tip collectors abreast. By this system the al…

Jute fabrics reinforced polyethylene (PE), polypropylene (PP) and mixture of PP+PE matrices based composites (50 wt% fiber) were prepared by compression molding. It was found that the mixture of 80% PP + 20% PE hybrid matrices based jute fabrics reinforced composites performed the best results. Gamma radiation (250–10…
The role of proteins in biomineralization has been examined in this work by studying the effect of ovalbumin on the stabilization of metastable CaCO(3) phases. In the absence of ovalbumin, the mixing of Na(2)CO(3) with CaCl(2) in an aqueous solution led to the formation of metastable phases that swiftly transformed in…
Magneto electric (ME) composites with the composition ( x )Ni 0.5 Zn 0.5 Fe 2 O 4 +(1− x )Ba 0.8 Pb 0.2 Zr 0.8 Ti 0.2 O 3 (BPZT—barium lead zirconate titanate), in which x varies as 0.0, 0.15, 0.30, 0.45, and 1.0 in molar ratio, were prepared by the conventional double sintering ceramic technique. The presence of two…
Pseudocapacitive characteristics of manganese (Mn) oxide were recognized in aprotic ionic liquid (IL), namely, butylmethylpyrrolidinium−dicyanamide (BMP−DCA), within a potential window of 3 V. The electrochemical energy storage mechanism was examined using X-ray photoelectron spectroscopy and in situ X-ray absorption…
The eigenvalues and eigenvectors of the dielectric matrix $ϵ$ provide a compact representation of the screening properties of interacting electronic systems. We have previously shown that the dielectric eigenvalue spectrum may be efficiently computed by iterative linear-response calculations and that for nonmetallic s…
The Pbcn orthorhombic phase of Y 2 Mo 3 O 12 has been examined through high-resolution X-ray powder diffraction (10−450 K), heat capacity determination (2−390 K), and differential scanning calorimetry (103−673 K). No phase transition was found over this temperature range. The overall thermal expansion is negative, and…
We present a new implementation of the cluster expansion formalism. The new code, UNiversal CLuster Expansion (UNCLE), consolidates recent advances in the methodology and leverages one new development in the formalism itself. As a core goal, the package reduces the need for user intervention, automating the method to…
The local deformation of steadily sheared two-dimensional Lennard-Jones glasses is studied via computer simulations at zero temperature. In the quasistatic limit, spatial correlations in the incremental strain field are highly anisotropic. The data show power law behavior with a strong angular dependence of the scalin…
