An approach using polychromatic x-ray Laue diffraction is described for studying pressure induced microstructural changes of materials under pressure. The advantages of this approach with respect to application of monochromatic x-ray diffraction and other techniques are discussed. Experiments to demonstrate the applic…
We report the electronic characterization of mesoscopic Hall bar devices fabricated from coupled InAs/GaSb quantum wells sandwiched between AlSb barriers, an emerging candidate for two-dimensional topological insulators. The electronic width of the etched structures was determined from the low field magneto-resistance…
The impact of orange peel coupling on spin current induced magnetization switching in a Co/Cu/Ni-Fe nanopillar device is investigated by solving the switching dynamics of magnetization of the free layer governed by the Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation. The value of the critical current required to i…
Helices are one of the most common and were among the earliest recognized secondary structure elements in proteins. The assignment of helices in a protein underlies the analysis of its structure and function. Though the mathematical expression for a helical curve is simple, no previous assignment programs have used a…
A carbazole-to-fluorene ratio in the molecular structure of the title polymers was found to have a strong effect on the morphology of their composites with the fullerene derivatives ([60]PCBM and [70]PCBM) and their photovoltaic performance.
Diagnosis and prognosis processes are necessary to optimise the dependability of systems and ensure their safe operation. If there is a lack of information, faulty conditions cannot be identified a ...
"Cyclodextrin-gas" clathrates were obtained by crystallization from water solution of α-, β-, and γ-cyclodextrins (CDs) under pressure of the gas to be entrapped into the CD molecules. When the pressure is released, these clathrates are stable at ambient conditions and dissociate at elevated temperature, which makes t…
The tribotechnical characteristics of radiation-modified polytetrafluoroethylene (PTFE) are studied at specific pressures of 10–20 MPa that correspond to the working conditions in the supports of engine rotors. It is shown that a mean coefficient of sliding friction of the modified PTEE is much lower than that of the…
The use of fiber-reinforced-plastics (FRP) contributes to an efficient implementation of lightweight design due to their outstanding specific mechanical properties. The RTM process offers great design freedom and allows the integration of functional elements during manufacturing. Embedded metal elements, so-called ins…
Plant cellulose synthases (CesAs) form a family of membrane proteins that are associated with hexagonal structures in the plasma membrane called CesA complexes (CSCs). It has been difficult to purify plant CesA proteins for biochemical and structural studies. We describe CesA activity in a membrane protein preparation…
Ageing assessment of transformer paper insulation is important due to its irreversible ageing nature. Due to the poor accessibility of the paper samples in field transformers, large efforts were made to seek for chemical parameters in oil to indicate paper ageing, e.g. furanic compounds and dissolved carbon oxides. In…
El sistema de frenado de un automóvil debe satisfacer un complejo conjunto de requerimientos, entre los cuales la seguridad es lo más importante. Los frenos deben trabajar en forma segura y predecible en cualquier circunstancia, lo cual implica disponer de un nivel estable de fricción, en cualquier condición de temper…
We studied the influence of different mask apertures on the open-circuit voltage measurement of perovskite solar cells. Aperture masks with different sizes were equipped to control the proportion of dark-state region. Statistical results of photovoltaic parameters, ideality factor, and reverse saturation current densi…
Precise control of magnetic domain wall displacement by a nanosecond current pulse in Co/Ni nanowires, Taniguchi, Takuya, Kim, Kab-Jin, Tono, Takayuki, Moriyama, Takahiro, Nakatani, Yoshinobu, Ono, Teruo
[C]RO6924963, [C]RO6931643, and [F]RO6958948 have been reported as promising PET tracers for tau imaging based on in vitro studies and preclinical PET data (Honer, HAI 2015). Here we describe the first evaluation of these novel radiotracers in humans (ClinicalTrials.gov: NCT02187627). Seven amyloid PET positive Alzhei…
Verbascoside or acteoside is the most abundant phenylethanoid glycoside that possesses health beneficial pharmacological activities, including anti-nociceptive, anti-inflammatory and anti-cancer. Due to the wide range of pharmacological activities of verbascoside and insufficient data on the safety profile, the acute,…
Abstract The aim of this paper is to study the influence of water on the mechanical properties of thermoplastic starch films. Experimental observations of Young modulus and the breaking force of thermoplastic starch foils with different percentages of polyvinyl alcohol and keratin additives and screw rotation speeds a…
PURPOSE: This study evaluated the effect of air abrasion and polishing regimens on the flexural strength of yttrium stabilized polycrystalline tetragonal zirconia (Y-TZP). METHODS: From Y-TZP blocks (InCeram 2000 YZ Cubes; Vita Zahnfabrik, Bad Säckingen, Germany) 120 bars (25 mm × 4 mm × 1.2 mm) were obtained accordin…
Cu doped SnO2nanoparticles were prepared using the chemical precipitation method. The Cu doped SnO2nanoparticles have been characterized by powder X-ray diffraction (XRD) analysis, Scanning electron microscopy (SEM), elemental dispersive X-ray (EDX) analysis, Transmission electron microscopy (TEM), UV-Visible absorpti…
This review systematizes and analyzes the physicochemical and catalytic properties of micro/mesoporous materials prepared by two-step recrystallization. The materials are divided into three groups according to the degree of recrystallization: (1) mesostructured zeolites (RZEO-1), (2) micro/mesoporous nanocomposites (R…
