Imaging plays an important role in the management of gynecological cancers. There is a clinical need for noninvasive prognostic biomarkers to provide more detailed tumor characterization at the baseline and/or early during therapy, which may potentially improve outcomes and enable a personalized treatment approach. Im…
Приведены результаты исследования микроструктуры и фазового состава слитков из модельных сплавов системы Al-Cu-Li-Mg.Показано влияние соотношения основных легирующих элементов на фазовый состав и структуру слитков в литом и гомогенизированном состояниях.Методом дифференциальной сканирующей калориметрии определены темп…
In this paper, a new structure of horizontal parallax light field 3D floating image display system was proposed. The structure consists of pico-projectors, Fresnel lens, micro-lens array and sub-lens array with freeform shape. By the functions of optical components, each light field of projectors could be controlled a…
Structural, Morphological and Electrical Properties of In-Doped Zinc Oxide Nanostructure Thin Films Grown on p-Type Gallium Nitride by Simultaneous Radio-Frequency Direct-Current Magnetron Co-Sputtering*, Perumal, R., Hassan, Z., Saravanan, R.
Front Cover: A multilayer nanocoating composed of polyelectrolytes and carbon nanotubes is able to render polyurethane foam flame retardant. This cover image represents the potential to protect household furniture from fire using this simple water-based coating. Further details can be found in the article by Kevin M.…
We report the results of a DFT study of the electronic properties, intended as highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energies, of periodic models of H-passivated armchair graphene nanoribbons (a-GNRs) as that synthetized by bottom-up technique, functionalized by vicin…
О механических свойствах углеродных наностержней и нановолокон из графенов при продольном растяжении и сжатии
Abstract An engineering analysis based on calibrated numerical predictions was performed to estimate the minimum allowable impurity concentrations in coal syngas intended to be used in Solid Oxide Fuel Cells (SOFCs) operating for over 10,000 h. Arsine and phosphine, impurities that are known to have the most deleterio…
We prove that the plane can be tiled with equilateral triangles and regular hexagons of integer sides using exactly one of each family.
1-Amino-3,6,9,12-tetraoxapentadecan-15-oic acid 8 was synthesised from tetraethylene glycol through a 7 step sequence including esterification, mesylation, azide substitution with subsequent reduction followed by hydrolysis. The structure of product 8 was identified by 1 H and 13 C NMR spectroscopy, elemental analysis…
aiming at a synthesis of the technical, sociology of knowledge, legal, societal, and political aspects of dose limits within the field of radioactive waste management. In this paper, the ENTRIA project is briefly introduced and the work on dose limits is put into the perspective of this much larger project. Selected a…
Crystalline III-V semiconductor nanowires have great potential in fabrication of nanodevices for applications in nanoelectronics and optoelectronics, and for studies of novel physical phenomena. Sophisticated epitaxy techniques with precisely controlled growth conditions are often used to prepare high quality III-V na…
A physically based continuum plasticity model for metals from the consideration of non-equilibrium thermodynamics is presented. The modeling is accomplished in a two-temperature framework that appears naturally by considering the thermodynamic system to be composed of two weakly interacting subsystems, namely the kine…

Abstract A (6, 14)‐connected metal‐organic framework (MOF), namely [Co9(μ3‐OH)2(CPT)10(HCOO)6]n (1) [HCPT = 4‐(4‐carboxyphenyl)‐1, 2,4‐triazole], was synthesized using custom‐designed bifunctional triazolate‐carboxylate organic linkers and CoII salts. The framework exhibits two types of highly connected Co3 and Co6 cl…
Summary Luminescent ruthenium diimine complexes have been covalently bound to the surface of a silica polyamine composite (SPC) using peptide coupling agents. The loading of the complexes using this route is quite low (∼0.01–0.04 mmol/g) leaving sufficient surface amines to coordinate added metal ions. When the compos…
Nanotubes and nanoparticles of SiC and Si3N4 were produced from the thermal treatment of peanut shells in argon and nitrogen atmospheres respectively, at temperatures in excess of 1350°C. Using x-ray diffraction, Raman spectroscopy and transmission electron microscopy analysis, the processed samples in argon atmospher…
Abstract This paper presents a novel method for determining the temperature of a radiating body. The experimental method requires only very common instrumentation. It is based on the measurement of the stationary temperature of an object placed at different distances from the body and on the application of the energy…
Solar energy conversion technology using semiconductors requires the transformation of a wide range of photons present in the solar spectrum into electricity or chemicals. This transformation involves a “complex” mechanism which proceeds via multiple steps, starting from photon absorption, electron–hole pair separatio…
Stem cells are being widely investigated for a wide variety of applications in tissue engineering due to their ability to differentiate into a number of cells such as neurons, osteoblasts, and fibroblasts. This ability of stem cells to differentiate into different types of cells is greatly based on mechanical and chem…
