Comparison of well-determined single crystal data for stoichiometric, or near-stoichiometric, metal hexaborides confirms previously identified lattice parameter trends using powder diffraction. Trends for both divalent and trivalent forms suggest that potential new forms for synthesis include Sc and Mn hexaborides. De…
In 2006, the Oklahoma Department of Transportation sponsored work at the pavement test track of the National Center for Asphalt Technology to compare the performance of two sections that had been designed to determine the necessary thickness for perpetual pavement. One section (Section N9) was designed to be a perpetu…
Cellulose hydrolysis is an important step in the production of bioethanol from cellulosic biomass. Two key cellulase enzymes, celB and β-glucosidase, were covalently immobilised on polystyrene treated with plasma immersion ion implantation (PIII) which creates radicals that form covalent bonds. The immobilized enzymes…
The reaction of the phosphate monoester {(ArO)PO(OH)2} (Ar = 2,6-i-Pr2C6H3) with BiPh3 in a 1 : 1 ratio in refluxing toluene afforded a tetradecabismuth-oxo-phosphate cage [{(ArO)PO3}10{(ArO)PO2OH}2(Bi14O10)·2(CH3OH)]·3C6H12·3CH3OH·2H2O (Ar = 2,6-i-Pr2C6H3) (1). On the other hand the reaction of the phosphate diester…
We report the synthesis, characterization and applications in Li-ion batteries of a set of 3-dimensional (3-D) nanostructured conducting oxides including fluorinated tin oxide (FTO) and aluminum zinc oxide (AZO). The morphology of these 3-D conducting oxide nanoarchitectures can be directed towards either mono-dispers…
A nanofibrous MnNi/CNF (carbon nanofiber) composite electrocatalyst with diameter of 50–200 nm was synthesized via electrospinning technique and followed by a carbonization process using polyacrylonitrile (PAN), manganese acetate and nickel acetate as raw materials. XRD analysis indicated that the manganese and nickel…
In integrated steelworks a large fraction of total CO2 is emitted from the power plant, where carbon- rich blast furnace gas (BFG) is burned to produce electricity by means of a steam cycle or a gas-steam combined cycle. The aim of the present paper is to assess the potential of Sorption Enhanced Water Gas Shift (SEWG…
Synthesis of a conjugated copolymer PF8CPDT10 comprising cyclopentadithiophene and fluorene units, investigation of its optical and electrochemical properties and evaluation of this material in organic bulk heterojunction solar cells and light emitting diodes are reported.
A series of systematically deplanarized push-pull oligothiophenes is designed and synthesized to determine the perfect twist for maximal spectroscopic response to their planarization within lipid bilayer membranes. Weak deplanarization naturally gives weak shifts, but strong deplanarization also gives weak shifts beca…
Due to high transparency and electrical conductivity, the transparent conductive glass applied in very large area like gas sensor, LCD, image storage device. It is also use in field of solar cell for both Si solar cell and Dye sensitized solar cell. Radio Frequency Plasma enhanced Reactive Thermal Evaporation method i…
Energy efficiency across a range of state of charge (SOC) is an important performance parameter in variable Battery Energy Storage System (BESS). A novel method was proposed to evaluate the effect of heat generation with the parameters of resistance and entropy change on the energy efficiency. The energy efficiency wa…
Objective: Both Bone Morphogenetic Protein 7 (BMP-7) and Transforming Growth Factor Beta 1 (TGF-β1) have stimulating effects on chondrocyte proliferation. These growth factors act at different time points of the biological repair process. We aimed to design a hydrogel, which would enable consecutive controlled release…
Luminescence techniques offer extremely sensitive probes of imperfections and structural changes in insulating materials. Among the many possible routes of signal excitation are the use of ion beams (IL) and the rarely used combination of ion beams with other excitation sources such as photons (PL), electrons (CL) or…
Geckos' outstanding abilities to adhere to various surfaces are widely credited to the large actual contact areas of the fibrillar and hierarchical structures on their feet. These special features regulate the essential structural compliance for every attachment and thus provide robust yet reversible adhesions. Inspir…
In an attempt to allow nuclear power to reach its full economic potential, General Atomics is developing the Energy Multiplier Module (EM2), which is a compact gas-cooled fast reactor (GFR). The EM2augments its fissile fuel load with fertile materials to enhance an ultra-long fuel cycle based on a “convert-and-burn” c…
The activity concentrations of naturally occurring 238U, 232Th and 40K in surface soils along Qarun Lake and Wadi El Rayan located in Faiyum, Egypt were determined. The measurements were carried out through gamma-ray spectrometry using a coaxial HPGe detector. The results were compared with those reported in the liter…
Herein is reported a facile and controllable route for coating polystyrene (PS) particles with palladium nanoparticle@polypyrrole (PdNP@PPy) nanocomposites based on the “Swelling–Diffusion–Interfacial-Polymerization Method” (SDIPM). The formation of PdNP@PPy nanocomposites was achieved by using palladium chloride as t…
Clarithromycin (CLA), a broad-spectrum macrolide, is a poorly soluble drug with dissolution rate limited absorption. The aim of this investigation was to prepare CLA nanoparticles from a ternary ground mixture in the presence of sodium lauryl sulfate (SLS) and polyvinyl pyrrolidone (PVP) as co-grinding water-soluble c…
Cardiac fibroblasts (CFs) produce extracellular matrix (ECM) which is a potent regulator of heart cell function and growth, and provides a supportive microenvironment for heart cells. Therefore, CF-derived ECM produced in vitro is very suitable for heart-cell culturing and cardiac tissue engineering. The aim of this s…
Commercialization of Lignin-based phenol formaldehyde resins (LPF) has been limited due to the increase in curing temperatures and decrease in adhesive strength of LPF compared to conventional phenolic resins. Lignin depolymerization can increase the reactivity of lignin; however, the effect of lignin molecular weight…
