We present quantitative predictions of the performance of nanotubes and nanowires as antennas, including the radiation resistance, the input reactance and resistance, and antenna efficiency, as a function of frequency and nanotube length. Particular attention is paid to the quantum capacitance and kinetic inductance.…
CeO2 nanocubes (and nanorods) enclosed by six {200} planes with controlled sizes have been prepared through a facile one-pot method. The nanocubes have a strong tendency to assemble into 2D and 3D arrays with regular patterns on a substrate, which is probably driven by the dipole-dipole interaction of polar {200} plan…

DOI: 10.2216/05-22.1Molecular sequence analyses have yielded many important insights into diatom evolution, but there have been few attempts to relate these to the extensive…
Cavities on a proteins surface as well as specific amino acid positioning within it create the physicochemical properties needed for a protein to perform its function. CASTp (http://cast.engr.uic.edu) is an online tool that locates and measures pockets and voids on 3D protein structures. This new version of CASTp incl…
Abstract— Results of the investigation of film polarizers on a base of polyvinyl alcohol and azobenzeneazonaphtalene dyes are presented. The dependence of the light stability of these polarizers on the structure and concentration of a dye, the stretching and conditions of the chemical treatment of films, as well as th…
The structure, magnetic properties and martensitic transformation behaviour were investigated for as-spun Co 50 Ni 20 Ga 30 ribbons under various heat-treatment conditions. When the as-spun ribbons were annealed at 400 °C, the saturation magnetization decreased from 49.5 to 40.1 emu g −1 and the coercivity increased f…
Lead zirconate titanate [Pb(Zr0.52Ti0.48)O3, PZT] thin films were deposited on Pt (111)/Ti/SiO2/Si and Pt (200)/Ti/SiO2/Si substrates by sol-gel method. Pyrolysis temperature and time were used to control the orientation of the thin films. A PbO buffer layer was also used to enhance the growth of (100)/(001) orientati…
Mathematically, the problem considered here is that of heteroclinic connections for a system of two second order differential equations of Hamiltonian type, in which a small parameter \epsilon conveys a singular perturbation. The motivation comes from a multi-order-parameter phase field model developed by Braun et al…
The deflection and time response of shape memory alloy laminated composite plate are studied using first order shear deformation theory. The composite plate consists of a thin layer of shape memory alloy bonded to an elastomer layer. The governing equations of the plate are developed using the energy balance equations…
Low-temperature CO oxidation over Au/oxides attracts alot of interest for its industrial and scientific importance. To date, it remains controversial where it occurs. Recently, Chen and Goodman suggested the reaction can occur on Au itself from their experiment of CO oxidation over $\mathrm{Au}∕\mathrm{Ti}{\mathrm{O}}…
Cloning, expression, purification and crystallization studies of a recombinant class C acid phosphatase from the Category A pathogen Bacillus anthracis are reported. Large diffraction-quality crystals were grown in the presence of HEPES and Jeffamine ED-2001 at pH 7.0. The crystals belong to space group P2(1)2(1)2(1),…
This paper presents a finite-element model for the free vibration analysis of a shape memory alloy (SMA) surface laminated composite cantilever plate. The proposed device is considered to undergo small displacements and small strains. The governing equations are developed utilizing the first-order shear deformation th…
The relationships between incommensurability, charge ordering and magnetic and electric transport properties were studied in La₀.₃₃Ca₀.₆₇Mn₁₋ᵧFeᵧO₃ (0 ≤ y ≤ 0.06) polycrystalline samples. Incommensurability and charge ordering were directly observed by electron diffraction versus temperature and lattice imaging at low…
We report the observation of sudden and dramatic changes in single-bubble sonoluminescence (SBSL) intensity (i.e., radiant power, phi(SL)) and spectral profiles at a critical acoustic pressure (P(c)) for solutions of sulfuric acid (H2SO4) containing mixtures of air and noble gas. Nitric oxide (NO), nitrogen (N2), and…
Abstract— The photoaligning properties of the popular photoaligning material polyvinyl‐4(fluorocinnamate) (PVCN‐F) are presented. The aligning quality and azimuthal and zenithal anchoring energy were measured and the drift of the easy orientation axis (gliding effect) on the PVCN‐F surface, depending on UV exposure, w…
We perform a full-wave analysis of a stackable lens proposed in a recent paper [Ramakrishna et al., J. Mod. Optics 50, 1419 (2003)]. This lens was suggested for improving subwavelength imaging and can be obtained by splitting a single-layer lens into a set of thinner layers. Our analysis shows that (i) such a lens, wh…
Ga2O3 thin films were deposited at 200°C on p-type Si (100) by plasma-enhanced atomic layer deposition technique with an alternating supply of reactant source, [(CH3)2GaNH2]3, and high-power oxygen plasma of 180 W. The as-deposited thin films were annealed at 500, 700, 900°C in oxygen ambient for 10 min in a rapid the…
Shape memory alloy (SMA) materials possess complete superelasticity or pseudoelasticity above the austenite finish temperature (Af) and many unique mechanical, thermal, thermal-mechanical and electrical properties compared with other conventional materials. Many studies have reported that the superelastic and hysteres…
Experiments have shown that the mechanical response of shape memory alloys is highly sensitive to the loading rate. The origin of this rate-dependent behavior, however, is not the usual viscoelastic effect, but rather it arises from the complex coupling that exists among stress, temperature, and the rate of heat gener…
Tethering of growth factors to biomaterial substrates via a polyethylene glycol (PEG) spacer has been established as a means of controlling dosage and conformation of the protein at the material surface, while retaining biological activity. However, the extent of modification through a comparison of bound versus unbou…
