Zinc stannates, including zinc hydroxystannate, are used components within synergistic fire retardant systems usually in conjunction with halogenated species in a number of polymers. Their behavior is similar to antimony III oxide (ATO) in that they enhance the effectiveness of the halogenated and, principally bromina…
White light-emitting diodes (WLEDs) with a hybrid poly N-vinylcarbazole (PVK) and poly(methyl methacrylate) (PMMA) polymer and ZnO quantum dots (QDs) were fabricated by a spin-coating technique. Transmission electron microscopy images showed that the ZnO QDs were predominantly distributed at the circumference of the s…
A planar sheet of carbon (graphene) or isoelectronic boron nitride has been decorated by Ti atoms for a high-capacity hydrogen storage material. Due to charge transfer, the Ti becomes cationic and helps to adsorb hydrogen in the molecular form. The principal bottleneck for using such a system for efficient H storage i…
Abstract In this paper we present results for a high power density IT‐SOFC and a method for dispersing nanosized Ce 0.9 Gd 0.1 O 1.95 (GDC) particles at the GDC electrolyte and Ni‐GDC anode interface. Dispersed nanosized particles were deposited to form an anode functional layer (AFL). Anode supports were prepared by…
The effect of shells of various thicknesses on the vibrational resonant Raman spectra of CdSe/ZnS core-shell nanoparticles is studied. The dependence of the core-shell structure on the method of shell deposition is derived from a comparison of the vibrational and photoluminescence spectra of nanoparticles. Along with…
In this work, we present ab initio studies of the electronic and transport properties of carbon nanoribbons with structural defects: divacancies and divacancies combined with the Stone-Wales-like (SW) defects. Simulations with defects in different positions with respect to the ribbons indicated that the total energy o…
As part of an investigation of new cathode materials for intermediate temperature solid oxide fuel cells, we have investigated several perovskite oxides with cobalt ions on the B sites in both bulk and thin film forms. Of particular interest is the composition La 0.5 Sr 0.5 CoO 3− x (LSCO) which has exceptional proper…
For the synthesis of biocompatible photothermal agents, gold nanorod-embedded polymeric nanoparticles (GPNs) were synthesized using a nanoprecipitation method. Uniform gold nanorods (GNRs), which are sensitive to a photothermal effect by near-infrared (NIR) light, with an aspect ratio of 4.0 were synthesized by a seed…
Uniaxial quasi-static tensile testing on individual nanocrystalline Co nanowires (NWs), synthesized by electrochemical deposition process (EDP) in porous templates, was performed inside a scanning electron microscope (SEM) using a microfabricated tensile stage consisting of a comb drive actuator and a clamped-clamped…
Molecular dynamics computer simulations were used to study the protonation of bridging oxygen (Si-O-Si) sites present on the vitreous silica surface in contact with water using a dissociative water potential. In contrast to first-principles calculations based on unconstrained molecular analogs, such as H(7)Si(2)O(7)(+…
[C 12 mim] 3 [DyBr 6 ] (C12mim = 1-dodecyl-3-methylimidazolium) represents a new material with interesting luminescent behavior as well as mesomorphic and magnetic properties. The compound was found to show thermotropic liquid crystalline behavior and forms smectic mesophases which were investigated by hot-stage polar…
An active structure of a morphing wing designed for subsonic cruise flight conditions is composed of three principal subsystems: (1) flexible extrados, (2) rigid intrados, and (3) an actuator group located inside the wing box. The four-ply laminated composite flexible extrados is powered by two individually controlled…
1D Cu(OH) 2 nanowires with a high yield were successfully synthesized under ultrasound irradiation of 40 kHz ultrasonic waves at the output power of 100% at 70 °C for 5 min without the assistance of any surfactant, employing CuCl 2 ·2H 2 O and NaOH as the initial materials. X-ray diffraction (XRD) analyses and field e…
Within the Dirac theory of the electronic properties of graphene, smoothly varying lattice strain affects the Dirac carriers through a synthetic gauge field. For static lattice strain, the gauge field induces a synthetic magnetic field which is known to suppress weak localization corrections by a dynamical breaking of…
Electric control of multiferroic domains is demonstrated through polarized magnetic neutron diffraction. Cooling to the cycloidal multiferroic phase of Ni3V2O8 in an electric field E causes the incommensurate Bragg reflections to become neutron spin polarizing, the sense of neutron polarization reversing with E. Quant…
Evenly spaced arrays: The unique molecular architecture of a self-assembled polypeptide template allows the electrostatic deposition of nanoparticles with uniform interparticle spacing. The hierarchical self-assembly mode of the polypeptide results in the display of charged patches at periodic distances along the leng…
Scaffolds that not only mimic the mechanical and structural properties of the target tissue but also support cell survival/growth are likely necessary for the development of mechanically functional cardiovascular tissues. To reach these goals, we have generated scaffolds that are elastic to approximate soft tissue mec…
Abstract A method to stabilize silver surface‐enhanced Raman spectroscopy (SERS) substrates for i n situ, high‐temperature applications is demonstrated. Silver island films grown by thermal evaporation were coated with a thin layer (from 2.5 to 5 nm) of alumina by atomic layer deposition (ALD), which protects and stab…
Nanoscale engineered materials with tailored thermal properties are desirable for applications such as highly efficient thermoelectric, microelectronic and optoelectronic devices. It has been shown earlier that by judiciously varying the interface thermal boundary resistance (TBR), thermal conductivity in nanostructur…
Rare earth (RE) ions (Tb 3+, Dy 3+, and Er 3+ ) are incorporated into ZnO nanostructures by a facile isocrystalline core−shell (ICS) protocol. Characteristic photoluminescence of rare earth ions has been observed for these doped nanocrystals. Effective doping has also been manifested by dramatic splitting and enhancem…
