In the rolling process, the upper and lower working rolls of the mill usually under different load. In order to keep good product quality, load balance control is necessary. This paper proposes a control method which uses the torque difference between upper and lower roll to compensate the given current of the upper r…
A model describing long-wave dimensional perturbations in a liquid film is developed that takes into account the presence of shear stress on the interfacial surface. This model is based on the decomposition of the liquid velocity vector components in a series in linearly independent basis functions (harmonics) and doe…
The electrical and photoelectric properties of polycrystalline Si are studied after the high-intensity short-pulse implantation of C ions. It is established that annealing in vacuum (10 –2 Pa, 300–1200 K) affects the characteristics of the surface dark conductivity and photoconductivity of Si. The optimal conditions f…
Semiconductors showing high efficient photocatalytic activity have attracted great interest, because they provide a potential solution to many environmental pollution problems that humankind is currently facing. This work reports on the sol-gel synthesis of Na2Ta4O11 nanocrystals and its photocatalytic performance tow…
Adv. Energy Mater. 2014, 4, 1301575 The labelled units on the depth axes of Figure 2 in the originally published article were shown as mm, but should instead be labelled as μm. The authors apologize for any inconvenience this may have caused.
Abstract Laser-assisted device alteration (LADA) is an established technique used to identify critical speed paths in integrated circuit. In this paper, the characterization of continuous wave 1340nm laser induced currents and the LADA failure rate show that a two photon absorption explanation for the LADA effect is n…
Abstract Magnetic current imaging (MCI) using superconducting quantum interference device (SQUID) and giant-magnetoresistive (GMR) sensors is an effective method for localizing defects and current paths [1]. The spatial resolution (and sensitivity) of MCI is improved significantly when the sensor is as close as possib…
Bi2WO6/ZnFe2O4integrated particles prepared by a facile two-step thermosynthesis possess large specific surface area and fair response to visible light so as to perform maximally photocatalytic decomposition toward rhodamine B under visible light irradiation. The morphology of the composite is influenced by pH value o…
Tensile-strained Ge/SiGe multiple quantum wells (MQWs) were grown on a Ge-on-Si virtual substrate using ultrahigh vacuum chemical vapor deposition on an n + -Si (001) substrate. Direct-bandgap electroluminescence from the MQWs light emitting diode was observed at room temperature. The quantum confinement effect of the…
Structure, magnetic properties, and magnetoimpedance (MI) of the nanocrystalline Fe73.5-xCrxSi13.5B9Nb3Cu1(x = 0%, 1%, 2%, 3%, and 5%) ribbons produced by rapid quenching after thermal annealing at 520 °C for 2 h were investigated with the aim to produce materials with different functional possibilities. It was shown…
Three samples of γ-Al 2 O 3 with different textural characteristics have been synthesized from AlOOH powders (Sasol). Ni(Co)Mo/Al 2 O 3 catalysts have been prepared by single impregnation of the γ-Al 2 O 3 samples with solutions of active ingredients. The morphology of the active phase of the sulfided samples has been…
In this work we present the band gap engineering, epitaxial growth and optical characterization of CdSe/Cd0.9Mg0.1Se and Cd0.9Mg0.1Se/Cd0.85Mg0.15Se quantum wells with a thickness ranging from 1 to 15 nm. These structures exhibit strong near-band-gap photoluminescence from helium up to room temperature. The emission e…
A finite-element definition of the stability problem for discretely-supported egg-shaped cylindrical shells made of a composite material is examined by considering the moments and nonlinearity of their sub-critical stressed-deformed state. The finite elements of a shell with natural curvature and beam-type supported e…
The main trends in the Russian nuclear industry are analyzed taking into account the development of the global nuclear industry. Measures of state support for all forms of financing for the Russian nuclear complex in 2005–2013 are assessed, as well as their impact on the relevant output growth.
γ‐Fe 2 O 3 nanoparticles coated with a layer of FeCl 3 ·6H 2 O were prepared by chemically induced transition in FeCl 2 solution. NaOH was added to the reaction solution, to investigate the effect of alkalinity on the resulting particles. Vibrating sample magnetometry, transmission electron microscopy, X‐ray diffracti…
Microwave complex permittivity measurements of different nanodiamond powders were measured (in the range of 10nm to 1µm). We have developed a low resolution, high accuracy broadband measurement system using our cylindrical cavity resonator consisting of 6 transverse magnetic (TM) modes ranging from 2.49GHz to 9.43GHz.…
We report recent progress in a novel cerium hydroxide polishing slurry with particle size of about 5 nm nano size cerium hydroxide (NSC) abrasive. NSC has succeeded in omitting particles over 1 μm, and in reducing scratches to 1/30 of those with calcined ceria slurry. Even though, NSC maintains oxide removal rate simi…
Abstract For VLSI, internal electrical measurements are key steps to solve design debug issues and to perform failure analysis. Due to multiple metal layers, active areas of the chip are only accessible from the backside of the die. The ability of optical contactless techniques to operate through the silicon substrate…
This paper addresses the fracture toughness ( ), or also known as critical stress intensity Factor, according to conditions of Lineal Elastic Fracture Mechanics (LEFM). The characterization of the mechanical properties in tensile and fracture toughness of structural steel pipes API-5L used in hydrocarbons transportati…
The isochoric thermal conductivity of solid tetrahydrofuran C4H8O (a cyclic hydrocarbon with pseudorotational motion of molecules) was studied using samples of different density in the temperature range 120−180 K. For all the samples, the isochoric thermal conductivity was found to decrease with temperature following…
