The aim of research is to develop an area of micro- and mesoporous ceramic materials of ternary - TiO 2 -ZrO 2 -SiO 2 system. Ceramic system TiO 2 -ZrO 2 -SiO 2 has been synthesized via a sol-gel technology by hydrolysis of tetraethylorthosilicate (TEOS) and zirconia propoxide and titanium isporopoxide solutions. The…
The electrooptic response of crystals becomes attenuated in the megahertz or higher frequencies where it is of the most use for communication systems. This research explores new possibilities of improved electrooptic interaction at high frequencies, discovered as a result of coupled electrooptic effects near selected…
In the design of fast reactor plants, the most important failure mode to be prevented is creep–fatigue damage at elevated temperatures. 316FR stainless steel is a candidate material for the reactor vessel and internal structures of such plants. The development of a procedure for evaluating creep–fatigue life is essent…
The phase delay induced by multilayer (ML) mirrors is an important feature in many fields such as attosecond pulses compression, photolithography or in pump and probe experiments performed with Free Electron Laser (FEL) pulses. The experimental characterization of the ML phase delay can be obtained by the standing wav…
The coexistence of various electronic and structural phases that are close in free-energy is a hallmark in strongly correlated electron systems with emergent properties, such as metal-insulator transition, colossal magnetoresistance, and high-temperature superconductivity. The cooperative phase transitions from one fu…

CdTexSe1-x, with its several advantages over the conventional CdZnTe (CZT) material, offers potential as a roomtemperature radiation detector. Its main advantage is the near-unity segregation coefficient of Se in the CdTe matrix that results in higher compositional homogeneity of the grown ingot. In this paper, we dis…
In this study, binary CdSe and ternary Zn0.5Cd0.5Se quantum dots (QDs) with monochromatic light are blended with conventional phosphors and those monochromatic lights of Zn0.5Cd0.5Se QDs are also mixed together and then packaged as remote type. Besides, white light CdSe QD are used alone to fabricate white light-emitt…
Resistance and magneto-resistance of nanocrystalline SrFe1−xTixO3−δ (x = 0 to 0.3) systems are investigated. Substitution of non magnetic Ti4+ stabilizes the single phase tetragonal crystal structure with I4/mmm space group and Ti introduces bond disorder as well as site disorder. With increase in Ti content, the diso…
High quality, controlled-structure nanowires (NWs), grown on a transparent flexible substrate, have attracted great interest as a mean of harvesting solar and mechanical energy. Clarifying their optical and piezoelectric properties is essential for this application. In this paper, vertically aligned lithium (Li) doped…
Abstract Invited for the cover of this issue is the group of Xuefeng Qian at Shanghai Jiao Tong University. The image depicts hydrogen being produced from water by solar energy. Read the full text of the article at 10.1002/chem.201403683 .
In this chapter, we will rst introduce the properties of various uorescent probes, including probes suitable for two-photon, near-infrared, or super-resolution imaging. The labeling methods as well as the underlying bioorthogonal reactions will next be discussed, followed by some examples in which small-molecule label…
Studies to determine the concentration of hydrogen peroxide (H2O2) are important in biological system due to cellular damages provoked by reative oxygen species that include H2O2. An alternative to detect H2O2 is through an optical nanosensors based on silver nanoparticles, which have great potential for chemical and…
We found that thin antimony films contacted by a single layer of a variety of atoms can form topological surface and interface states in the gap of bulk energy bands that preserve time-reversal symmetry. Using density functional calculation, we have included bismuth, graphene, boron-nitride and boron-doped graphene la…
Two different approaches to the creation of "rigid" (gel-like) DNA particles (or DNA nanoconstructions) are considered. The physicochemical approach is based on the formation of nanobridges between double-stranded DNA molecules ordered in quasinematic layers of cholesteric liquid-crystalline dispersion (CLCD) particle…
We formalize the theoretical effects of optical resonator enhancement on diffraction efficiency, read rate, and write rate of plane wave holograms, with a view toward page based holographic data storage. Trade-offs in cavity enhancement are also examined. Theory predicts ~160% of enhancement in diffraction efficiency…
Bulk tellurium (Te) presents a threefold screw axis with highly anisotropic chain structure, where every Te atom forms strong covalent bonds in the chain and much weaker bonds in the adjacent chains. The bonds in the adjacent chains are critical to the total energies of Te nanostructures since the nearest neighbors ar…
Abstract A new scattering particle structure, dense core–mesoporous outer layer beads, was designed and synthesized by a one-pot hydrothermal method. Though the particle size was much larger than that of the conventionally used scattering particles, the photovoltaic performance was superior to that of 500-nm rutile pa…
Advantages of neutron diffraction for metallurgical studies are highlighted with research examples performed on the High Pressure - Preferred Orientation diffractometer at the Los Alamos Neutron Science Center. The previously inconclusive crystallographic structure of the Fe–Al ϵ-phase, stable between 1095 and 1231°C,…
The active conformation of a family of metabotropic glutamate receptor subtype 4 (mGlu4 ) positive allosteric modulators (PAMs) with the cyclohexane 1,2-dicarboxylic scaffold present in cis-2-(3,5-dichlorophenylcarbamoyl)cyclohexanecarboxylic acid (VU0155041) was investigated by testing structurally similar six-member…
