The phosphors of calcium stannate activated with individual trivalent rare-earth element (REE) ions (Neodymium III, Europium III, Terbium III, Dysprosium III, and Samarium III) were synthesized by high-temperature solid-state reaction (SSR), and their characterization and luminescent properties were investigated. The…
Maleimide is a stable and easy-to-handle moiety that rapidly and covalently conjugates thiol groups of cysteine residues in proteins or peptides. Herein, we use maleimide to modify the surface of liposomes in order to obtain an advanced drug delivery system. Employing a small amount (0.3 mol%) of maleimide-polyethylen…
Abstract A compositional gap between sepiolite and palygorskite has long been accepted even though they have similar structures, but recent studies found that such a gap does not exist and that the compositional series is continuous between them. If this is true, intergrowths between these two minerals should exist. T…
The Hugoniot elastic limit, the yield strength, and the spall strength of polycrystalline M1 copper and single-crystal (110) and (111) copper are determined during shock compression up to 8 GPa in the temperature range 20–1080°C from an analysis of the free-surface velocity profiles recorded with VISAR laser velocimet…
La-filled skutterudites (La z Fe 4- x Co x Sb 12 ) were prepared by encapsulated melting and hot pressing, and filling and doping (charge compensation) effects on the transport and thermoelectric properties were examined. The signs of the Hall and Seebeck coefficients were positive and it means that the majority carri…
Graphene-based epoxy nanocomposites have been produced by the ultrasonication of graphene oxide (GO), chemically modified GO and through two-phase extraction of GO water solution. All the samples have been post-cured and the thermal treatment provided a thermal in situ reduction of GO into the epoxy reticulated matrix…
With the development of materials science and technology, performance and preparation of polymer materials becomes a hot topic. The heat resistance and corrosion resistance of Polymer material are strong and can be manufacture for composite materials. It is widely used in many areas. This paper adds metal shielding ma…
Specific heat of barium titanate single crystals of different quality has been precisely measured with special attention to the temperature region above the ferroelectric phase transition. It was assumed that excess specific heat in the paraelectric phase has a fluctuation nature and the experimental data were analyze…
The paper presents a variant analysis of the structure of SOFC hybrid system. The systems are divided into two gropus: atmospheric and pressurized. The main parameter of such systems are indicated and commented. The comparison of various configurations is shown in a view of efficiency obtained. The ultra high efficien…
The mineral glauberite is one of many minerals formed in evaporite deposits. The mineral glauberite has been studied using a combination of scanning electron microscopy with energy dispersive X-ray analysis and infrared and Raman spectroscopy. Qualitative chemical analysis shows a homogeneous phase, composed by sulfur…
Background: Carbon nanotube (CNT) mediated drug delivery systems have recently aroused a great deal of interest. Such delivery systems for drugs, proteins and genes have been preliminarily studied using cellular and animal models. For further study of the related biological behaviours of CNTs in vivo, a fast and conve…
Detailed molecular dynamics simulations have been performed to explore the effect of guiding layer properties and errors on resulting directed self-assembly pattern properties produced in block copolymer (BCP) thin films. Guiding patterns that are noncommensurate to the natural BCP pitch are considered, as are guiding…
We fabricated indium nitride (InN) on porous silicon (PSi) on crystalline silicon [Si(100)] heterostructure photodetector via radio frequency sputtering. PSi layer was synthesised on n type Si(100) wafers via photoelectrochemical etching. Large area PSi, which comprised an array of voids, was used as an intermediate l…
The dendrimer molecules are spontaneously attached to the interface of liquid crystal microparticles dissolved in a glycerol matrix, forcing directors perpendicular to the interface. Photoisomerization reorients them from radial to tangential to the interface in the nematic, cholesteric and smectic A phases showing ch…
We report the catalytic oxidation of cyclohexane to CO and CO2 over size-selected palladium clusters (Pd N clusters, N = 10–120) supported on graphite as a function of cluster size. The stability of the pinned clusters (nanoparticles) under reaction conditions is investigated by scanning tunnelling microscopy measurem…
RbNaCaTh(Si 8 O 20 ), which crystallizes in the turkestanite structural type, was synthesized by a solid-phase reaction for the first time. The crystal structure of this compound was refined by the Rietveld method (space group P 4/ mcc ). The temperature dependence of the unit cell parameters was studied using high-te…
The partitioning of phosphorus between olivine and melt was measured by conducting partitioning experiments within the system Mg 2 SiO 4 -Ca 2 Al 2 Si 2 O 9 -NaAlSi 3 O 8 -Mg 3 (PO 4 ) 2 , using olivines crystallized with cooling rates in the range 1 to 10 °C/h. Partition coefficients, D P ol/melt , vary from 0.05 to…
By using first-principles calculations, we have systematically investigated the phase stability, magnetism and electron-filling behavior of vanadium-based inverse Heusler compounds. Our calculation results indicate that, due to the complex hybridization of the d orbitals for the vanadium atom, the electronic structure…
Abstract In order to reduce eye strain, a driving method for reducing flickers of liquid crystal display (LCD) is devised. For this driving, an oxide semiconductor (OS) is used in a backplane, liquid crystal and alignment layer materials are optimized, and a fringe field switching (FFS) mode with a structurally formed…
A novel homologous series α-4-[4′-n-Alkoxy benzoyloxy] benzoyl β-4″-methoxy phenyl ethylenes of 12 homologue substances is presented and comprises of 5 compounds (heptyl to tetradecyl) that exhibit both a smectic and a nematic phases. The pentyl, hexyl, and hexadecyl homologues only exhibit the nematic without exhibit…
