The ITER correction coils (CCs) are designed to be arranged toroidally around the machine inside the poloidal field coils and mounted on the toroidal field coils in order to compensate field errors arising from misalignment of the coils and winding deviations from the nominal shape as a result of fabrication tolerance…
The stress caused by vortices in tetragonal superconductors contributes to the intervortex interaction which depends on vortex orientation within the crystal, on elastic moduli, and is attractive within certain angular regions even in fields along the $c$ crystal axis. For sufficiently strong stress dependence of the…
Abstract The first rare‐earth metal telluride chlorides, R TeCl with R = La, Ce, Pr, Nd, were obtained as single crystals and/or powder samples by the reaction of anhydrous rare‐earth trichlorides, R Cl 3 , with the respective rare‐earth metals R and elemental tellurium (Te) in sealed tantalum containers at temperatur…
Surface plasmon resonance modes in a two-dimensional gold nanodisk array incorporated with super-lattice defects are investigated in this paper. Both transmission and absorption spectra of the super-lattice metal nanodisk array are calculated. The transmission spectrum exhibits an asymmetric Fano resonance lineshape a…
Platinum nanotubes are created by galvanic deposition inside porous templates. The effects of the electrolyte's ion concentration and pH, of the applied potential and of the deposition duration on the morphology of the tubes are investigated systematically. The system provides a model electrode platform with accuratel…
Reaction of Ti(OiPr)4 with several tri- and tetracarboxylic acids, followed by hydrolysis, resulted in microporous, structured materials, with microporous surface areas up to 340 m(2) g(-1). Depending on the kind of carboxylic acid, the Ti : COOH ratio and the Ti : H2O ratio, either pillared layered or surface fractal…
RLIP76 is an effector for Ral small GTPases, which in turn lie downstream of the master regulator Ras. Evidence is growing that Ral and RLIP76 play a role in tumorigenesis, invasion, and metastasis. RLIP76 contains both a RhoGAP domain and a Ral binding domain (GBD) and is, therefore, a node between Ras and Rho family…
A new technique based on cubic spline interpolation with Savitzky-Golay noise reduction filtering is designed to estimate signal-to-noise ratio of scanning electron microscopy (SEM) images. This approach is found to present better result when compared with two existing techniques: nearest neighbourhood and first-order…
Solare Brennstoffe: Verschiedene n- und p-Halbleiter wurden für die Herstellung nachhaltiger solarer Brennstoffe getestet. p-Halbleiter wie NiO, Fe3O4, Co3O4 und CuO können Kohlenmonoxid mit Wasser oder Wasserstoff zu Methan reduzieren (siehe Bild). Die höchste Methanausbeute lag bei 17.26 mmol Methan pro Katalysatorg…
Modelling and mitigation of damage are crucial for safe and economical operation of high-power laser facilities. Experiments at the National Ignition Facility use a variety of targets with a range of laser energies spanning more than two orders of magnitude (~14 kJ to ~1.9 MJ). Low-energy inertial confinement fusion e…
An ionic polymer metal composite (IPMC) is a kind of electro-active polymer. Due to the properties of low driving voltage, large deformation, flexibility and lightness, it is becoming one of the more popular from a diversity of smart materials. In this study, a novel structure of Nafion ® film is proposed to improve t…
This paper reports on a novel non-contact thermal imaging method with high spatial, temporal and temperature resolution for microdevice evaluation. This method uses a temperature sensitive paint with europium (III) thenoyltrifluoroacetone (Eu(TTA) 3 ). The luminescence of Eu(TTA) 3 was excited by a short pulsed UV lig…
Thermal analysis and SEM were employed to gain insights in the different stages of morphology development and the thermal properties of polymer-monolithic stationary phases. The studied system was a thermally initiated free-radical copolymerization reaction at 70°C of styrene and divinylbenzene in the presence of tetr…
Abstract Crystallized 4,7‐diphyenyl‐1,10‐phenanthroline (BPhen) films deposited by convenient vacuum thermal evaporation technique have been found to be an efficient means to extract the substrate wave guided light in organic light emitting diodes (OLEDs). The optimized BPhen film working as organic scattering layer w…
The formation process and characterization of mixed layers of 11-mercaptoundecanoic acid (MUA) and octanethiol (OT) on Au(111) single crystal electrodes under electrochemical control from alkaline solutions are analyzed in this work by means of electrochemical techniques such as chronocoulometry, cyclic voltammetry, a…
β-Sheets have been implicated in various neurological disorders, and ∼20% of protein residues adopt a sheet conformation. Therefore, studies on the structural origin of sheet stability can provide fundamental knowledge with potential biomedical applications. Oppositely charged amino acids are frequently observed acros…
The synthesis and mechanical properties of ABA triblock copolymers containing benzene-1,3,5-tricarboxamide (BTA) moieties in the middle block are described. The triblock architecture was achieved by sequential polymerization of different monomers by atom-transfer radical polymerization (ATRP). The ABA triblock copolym…
Pipeline transportation of resources is considered a vital method due to low operational cost, and simple design and implementation. However, potential leaks compromise the integrity of this method. Pipeline leaks consequences are major concerns due to resources loss, environmental impact and potential human injuries…
PURPOSE: MRI is used to obtain quantitative oxygenation and blood volume information from the susceptibility-related MR signal dephasing induced by blood vessels. However, analytical models that fit the MR signal are usually not accurate over the range of small blood vessels. Moreover, recent studies have demonstrated…
We developed a Schottky barrier diode (SBD) embedded AlGaN/GaN switching transistor to allow negative current flow during off-state condition. An SBD was embedded in a recessed normally-off AlGaN/GaN-on-Si metal-oxide-semiconductor heterostructure field-effect transistor (MOSHFET). The fabricated device exhibited norm…
