The experimental study is done for technological parameters of high-melting metal arc spraying to study the influence of spraying current, spraying voltage and wire feed voltage on spraying arc and the influence of spraying current on coating temperature and analyze theoretically the distribution rules of spray gun je…
Gold nanorod end-to-end assembly is demonstrated by the selective complexation of a bisacridinedione foldamer with Ca(2+). This setup can be applied as a chemosensor for Ca(2+) ions, as the complex shows selective red-shifting of the nanorod plasmon peak and enhancement in fluorescence from the acridinedione moieties…

By functionalizing lithographically defined posts with a brush consisting of the majority block of a block copolymer, various morphologies can be formed in a templated self-assembled pattern, as reported by K. K. Berggren, C. A. Ross, and co-workers on page 4249. In the cover image, square-symmetric post arrays produc…
In this communications, the concept of the pathos vertex semientire graph of a tree is introduced. We present characterization of graphs whose pathos vertex semientire graph of a tree is planar, outerplanar and minimally nonouterplanar. Also we establish a characterization of graphs whose pathos vertex semientire grap…
Freestanding graphene membranes were functionalized with SnO2 nanoparticles. A detailed procedure providing uniform coverage and chemical synthesis is presented. Elemental composition was determined using scanning electron microscopy combined with energy dispersive x-ray analysis. A technique called electrostatic-mani…

One of the major forces driving the birth of the field of cell biology was the application of electron microscopy to cells. Today, virtual nanoscopy has brought electron microscopy and the cell biology community to a new frontier in biological imaging and cell biological inquiry. The Journal of Cell Biology is pleased…
Anodic porous alumina has broad applications for fabricating self-assembled nanostructures, for which atomistic understanding of ionic transport at pore surfaces is indispensable. Here, molecular-dynamics simulation of amorphous alumina with a cylindrical pore under electric field shows correlated anion (oxygen)-catio…
Different aluminosilicates, such as montmorillonite, vermiculite and mica, were surface-treated with a variety of organic modifiers to quantify factors affecting the thermal stability of the modified fillers. Montmorillonites with different cation exchange capacities were also used. Thermal characterisation was carrie…
In this letter, we formulate and investigate the optical performance of finite arrays of plasmonic nanorod antennas in randomly tilted disordered and Fibonacci configurations. To efficiently model the scattering performance of a nanorod, we take advantage of characteristic basis function method in conjunction with mac…
Abstract Proton‐irradiation has been realized on Fe‐contaminated p‐type Czochralski silicon and investigated for interaction between Fe and irradiation‐induced defects using deep level transient spectroscopy. From isochronal thermal annealings, three distinctive Fe‐related defects are observed with energy level positi…
A new class of neutral receptors based upon acylhydrazide-appended calix[4]arenes was synthesised and evaluated for recognition of anions. Detailed NMR and single-crystal X-ray analyses of one of the synthesised compounds reveal that anion recognition in such derivatives is achieved through cooperative hydrogen bond i…
Corona stabilized switches have been shown to have advantages in pulse power switching applications due to their high repetition rates and low jitter. Work performed in recent years by the High Voltage Technologies Group within the Department of Electronic and Electrical Engineering at the University of Strathclyde ha…
In this paper, we complement our previous work on the study of low-temperature rectifying junctions based on Ag/ZnO Schottky barriers. Diodes characterized by very highION/IOFFratio and ideality factors considerably higher than unity, in disagreement with the thermionic emission model, are modeled with a 2-D finite-el…
First-principles calculations are carried out to estimate the spontaneous polarization and the band gap bowing in the ScxAlyGa1 − x − yN alloys lattice-matched to GaN based on the density functional theory together with a pseudopotential plane-wave method. The results indicate nonlinear behavior of the spontaneous pol…
MnO2/ordered mesoporous carbon (OMC) composites were prepared by a novel technique named as incipient wetness impregnation–hydrothermal method, which can prepare composites with relatively poorer crystallinity with high performance, and the effect of loading amount on the structure and capacitance performances of the…
Developments in measuring sound velocity of matter under ultrahigh pressure are described. We employed a time-resolved x-ray shadowgraph technique to measure the sound velocity of shock-compressed diamond and iron foils at around melt. The sound velocity significantly dropped at melting, a behavior that has been diffi…
The cyclotron resonance energies, the corresponding oscillator strengths, and the cyclotron absorption spectrum for trilayer graphene are calculated for both ABA and ABC stacking. A gate potential across the stacked layers leads to $(1)$ a reduction of the transition energies, $(2)$ a lifting of the degeneracy of the…
Abstract Hydrogenated nanocrystalline silicon (nc-Si : H) films were grown using the plasma-enhanced chemical vapour deposition method, with the plasma operated under a gas pressure of up to 30 mbar, i.e. on the verge of plasma instability. The heating effect in determining the crystallite size and crystalline volume…
