Both low-dimensional bar-coded metal oxide layers, which exhibit molecular hinging, and free-standing organic nanostructures can be obtained from unique nanofibers of vanadium oxide (VO(x)). The nanofibers are successfully synthesized by a simple chemical route using an ethanolic solution of vanadium pentoxide xerogel…
Part 1 Advances in apparel design: Measuring and predicting fabric and garment drape Computer aided colour matching of apparel fabric Computer-assisted yarn design Improving apparel sizing and fit Three-dimensional body scanning to improve apparel fit Computer-assisted garment design using three-dimensional body model…
Since sulfur compounds are the major poisons of fuel cell systems, equilibrium concentrations of minor sulfur-based impurities in fuel cell fuels are thermochemically calculated in the temperature range between 400°C and 1000°C. As sulfur-based impurities in fuel cell gases, H2S(g), elementary sulfur, inorganic sulfur…
A model to predict the density of metallic nanostructures (see image) during an electrochemical deposition process is presented. The quantitative consideration of pH gradient inside high-aspect-ratio nanostructures coupled with a kinetic model allows a quantitative prediction of the structure morphology depending on n…
We have investigated the magneto-elastic effect at the antiferromagnetic phase transition in ${\text{LaMnO}}_{3}$ by neutron powder diffraction. The intensity of the (001) magnetic reflection decreases continuously to become zero at ${T}_{N}\ensuremath{\approx}141\text{ }\text{K}$ indicating a second-order antiferroma…
We have developed a theory that unifies the analysis of the modal properties of surface-emitting chirped circular grating lasers. This theory is based on solving the resonance conditions which involve two types of reflectivities of chirped circular gratings. This approach is shown to be in agreement with previous deri…
A hierarchical assembly of carbon nanofibers (CNFs), Pd−Sn nanoparticles, and carbon nanotubes (CNTs) was synthesized based on the template method. The metal particles were first immobilized on the pore walls of an anodic aluminum oxide (AAO) template. The following pyrolysis of C 2 H 2 in the AAO pores simultaneously…
ZnO powders were synthesized in the presence of water-soluble polymers. These polymers have effects on the nucleation and growth of ZnO crystals in solution, resulting in difference in crystalline morphologies. The role of polymers is 2-fold: first, indiscriminating adsorption of Zn(II) ions onto the polymer surfaces,…
We extend the previously established mode-expansion theory to study the eigenmodes of metallic ring systems made by thin wires possessing filmlike rectangular cross sections. Applications of the theory to a single split-ring resonator (SRR) yield essentially the same results with finite-difference-time-domain (FDTD) s…
Mechanical stress generation during epitaxial growth of Fe–Pd thin films on MgO from pulsed laser deposition is a key parameter for the suitability in shape memory applications. By employing in situ substrate curvature measurements, we determine the stress states as a function of film thickness and composition. Depend…
A water-soluble, hydrophilic tripeptide GYE, having sequence identity with the N-terminal segment of amyloid peptides Abeta(9-11), upon self-association exhibits amyloid-like fibrils and significant neurotoxicity towards the Neuro2A cell line. However, the tripeptides GFE and GWE, in which the centrally located tyrosi…
Abstract The frequency upconversion emissions of NaYF 4 nanocrystals embedded in transparent glass ceramics codoped with Yb 3+ /Er 3+ , prepared by melt quenching and subsequent heating, were investigated. It was found that, compared with that of the sample singly doped with 0.5Er 3+ , the intensities of the green and…
Highly fluorescent organic nanoparticles with size of about 300 nm were prepared by nanosecond laser ablation of micrometer-sized powder of dendronized perylenediimide dispersed in water. The nanoparticle colloidal solution provided a fluorescence quantum yield of 0.58. The absorption and emission spectral studies dem…
In a bioinspired methodology, positively charged polypeptides and polyamines directly catalyse ZnO mineralization under "green" conditions of room temperature and neutral pH. The polyamines not only act as mineralizing agents for the formation of ZnO nanoparticles, but also self-assemble the nanoparticles to form spin…
Reverse Monte Carlo (RMC) refinements using a combined real-space fit of the neutron/X-ray total scattering pair-distribution function (PDF) and the extended X-ray absorption fine structure (EXAFS) were developed and implemented as an extension to the public domain computer software RMCProfile . The effectiveness of c…

We have produced hybrid liposomes (HL) which can be prepared by ultrasonicating a mixture of dimyristoylphosphatidylcholine (DMPC) and polyoxyethylene(23)dodecyl ether in a buffer solution. The fifty-percent inhibitory concentration (IC50) of HL on the growth of human B lymphoma (RAJI) cells in vitro was determined. T…
NO 2 adsorption on activated carbons at ambient temperature was studied. The adsorbed species after various adsorption times were examined by analyzing the evolution of NO, NO 2, CO, CO 2, and O 2 during thermal desorption. Emission of NO but not NO 2 was observed during the early stage of NO 2 adsorption. From the ni…
We present a robust method for synthesis of aligned, single-walled carbon nanotube (CNT) "flying carpets" from nanostructured alumina flakes. Roll-to-roll e-beam deposition is utilized to produce the flakes, and hot filament chemical vapor deposition is utilized to grow dense, aligned carbon nanotubes from the flakes…
