The sub-20nm region is an emerging technology for the next generation of powerful microscopes, telecommunications, and high-performance computing devices. Such applications require pushing the limits of nanofabrication to new levels of precision and control. With an accuracy in the sub-5nm region, helium ion beam mill…
This extended abstract briefly summarizes ongoing research activity on the evaluation and experimental validation of physics methods for photon and electron transport. The analysis includes physics models currently implemented in Geant4 as well as modeling methods used in other Monte Carlo codes, or not yet considered…
In 2009, the Emirates Nuclear Energy Corporation (ENEC) was launched as a step into providing clean, safe and efficient nuclear energy in the UAE. As oil reserves decline, ENEC aims to satisfy about 25% of the energy demand of the UAE by 2020. For this purpose, initial drilling for the set-up of four nuclear reactors…
In the search for mechanisms of high-temperature superconductivity it is critical to know the electronic spectrum in the pseudogap phase from which superconductivity evolves. The lack of angle-resolved photoemission data for every cuprate family precludes an agreement as to its structure, doping and temperature depend…
This paper describes the manufacture and properties of self reinforced polymer hybrid composites based on a combination of carbon fibres and oriented polyamide 12 fibres and tapes. Three different hybridisation techniques (intra-yarn, intra-layer and inter-layer) were investigated. In intra-yarn hybridisation, tows we…
Here we present the theoretical clarification of possibility of eight Majorana-like modes (quasi-particles which are self-conjugate) close to the experimentally inaccessible Dirac points of a two-dimensional monolayer Dirac system. The valley-mixing and the spin-degeneracy lifting are the main requirements. These are…
The paper presents the decision for the question of the excessive catalytic collector high frequency noise in the automobile engine exhaust system. The high level noise has been observed under the idle state engine condition. In order to understand the causes of the high catalytic collector noise emission the research…

Einen Ausflug ins Amorphe unternehmen R. Mazzarello, R. Dronskowski et al.: In ihrer Zuschrift auf S. 10993 ff. berichten sie über die Bindungsverhältnisse in amorphem GeTe, einem prototypischen Phasenwechselmaterial zur Datenspeicherung. Ausgehend von einem Moleküldynamik-Schnappschuss analysieren sie die Rolle versc…
In this paper, we investigate the adsorption of a series of rare-earth (RE) metal atoms ( La , Pr , Nd , Sm and Eu ) on the pristine zigzag (8, 0) silicon carbide nanotube ( SiCNT ) using density functional theory (DFT). Main focuses are placed on the stable adsorption sites, the corresponding binding energies, and th…
ABSTRACT Directed delivery of mesoscaled cargo—for example, nanocrystals, proteins, or nucleic acids—to cells using polymer vectors impacts numerous biomedical fields. We introduce here the concept of dynamic complementarity as a simple, yet powerful approach to control the rate of mesoscaled cargo dissociation from c…
用CaCl 2 、La（NO 3 ） 3 和Ce（NO 3 ） 3 溶液对NaY分子筛进行离子改性制备出CaY、LaY和CeY分子筛。将其及NaY为吸附剂，利用动态吸附法评价其吸附分离1，1，1，2-四氟乙烷（HFC-134a）产品中微量1，1-二氟-2-氯乙烯（HCFC-1122）的性能。同时采用X射线衍射（XRD）、吡啶红外（FTIR）和氨-程序升温脱附（NH 3 -TPD）等手段对新鲜及再生后的吸附剂进行结构和表面性质表征。结果表明：CaY、LaY与CeY分子筛上的Bronsted酸中心可与HCFC-1122形成p-吸附配合物，从而将吸附流出气中HCFC-1122的残余率降低至1.0%以下；Bronsted酸强度越高，p-吸…
The morphology and chemical composition of InxGa1-xAs NWs grown on undoped GaAs (111)B substrate have been investigated using scanning electron microscopy (SEM) and energy dispersive x-ray (EDX), respectively. SEM images show that InxGa1-xAs NWs underwent morphological evolution as temperature changes. By changing the…
ABSTRACT A novel terpolymer ligand involving 2‐amino‐6‐nitro‐benzothiazole–semicarbazide–formaldehyde was synthesized in a 1:1:2 mole ratio with a dimethylformamide reaction medium at 150 ± 2°C for 6 h. The synthesized ligand was used to prepare various metal complexes with Cu2+, Ni2+, and Zn2+ metal ions. The structu…
We demonstrate top-gate tunable Josephson junction like behavior in the two dimensional electron gas at the LaAlO$_3$-SrTiO$_3$ interface. A combination of global back-gating and local top-gating is used to define the junctions, providing an efficient way for much finer spatial control over the properties of the inter…
A new metal–organic crystal, β-alanine cadmium bromide monohydrate (β-ACBM) has been grown from aqueous solution by slow evaporation technique. The grown crystals have been subjected to single crystal X-ray diffraction to determine the crystal structure. The β-ACBM crystallized in monoclinic system, which belongs to t…
In this paper, we investigate some relations between the invariants (including vertex and edge connectivity and forwarding indices) of a graph and its Laplacian eigenvalues. In addition, we present a sufficient condition for the existence of Hamiltonicity in a graph involving its Laplacian eigenvalues.
Results of investigations into the effect of chromium, which determines corrosion resistance, and its content in specimens of deposited metal on EK77 alloy varies in the range 21.1–20.8%, are presented. The optimum ratio of the alloying elements chromium, copper, manganese and silicon is determined. Data for the corro…
