Here we present preliminary experiments for synthesis of carbide materials from bacterial cellulose that has been infiltrated with tungsten trioxide nanoparticles. Bacterial cellulose decomposes to carbon upon heat treatment around 900 °C. Upon further heat treatment in the presence of the metal oxide, this carbon rea…
Solid oxide fuel cells (SOFCs) are devices that can convert chemical energy to electricity directly with high efficiency and fuel flexibility. Here, we fabricate perovskite single crystal thin films as cathodes with the composition of Ba0.95La 0.05FeO3-δ (BLF) by pulsed laser deposition (PLD) on yttria-stabilized zirc…
Solid oxide fuel cells (SOFCs) have attracted significant attention over recent years due to their promising use as source of clean and efficient power generation. Towards the goal of enhancing the efficiency of these devices, it is important to eludicate the mechanisms governing fundamental electrochemical processes,…
This specification covers cylinder burst disk assemblies for paintball marker propellant sources their application and installation requirements. The materials and processes used to manufacture the burst disk assembly shall result in items with mechanical strength sufficient to pass the applicable burst pressure tests…
Abstract Brownian motion, where microscopic particles are immersed in a fluid, is described separating the time scales of the collision with individual molecules and the macroscopic viscous friction. This separation permits derivation of the kinetic equation, which corresponds to a family of Fokker—Planck equations. A…
Nanoparticles of tin dioxide going through sintering. Contact angles between particles define pore volume. This system is a great example of how thermodynamics of interfaces strongly control densification and grain growth of ceramics. Image was obtained using Scanning Transmission Electron Microscopy (by Sanchita Dey,…
The eutectic Ag-Cu composition is a common brazing alloy. A complex ion bath containing KAg(CN)2, CuCN, KCN and K4P2O7 was used to codeposit Ag and Cu. The effects of KAg(CN)2, KCN and K4P2O7 concentrations on the composition and morphology of electrodeposited Ag-Cu films was investigated in this study. A constant CuC…
Silicon nanowires (SiNW’s) arrays prepared by electroless etching method are attractive due to their significant light absorption properties across the visible spectrum [1]. Typical silicon nanowires grown by electroless etching is shown in Figure 1a. Following this preparation of silicon nanowires, these samples are…
Competitiveness is one of the most important factors in our lives and it plays a key role in the efficiency both of organizations and societies. The more scientifically advanced and prepared organizations develop more competitive materials with better physical, chemical, and biological properties, and the leading comp…
General Engineering & Research, L.L.C. (GE&R) has developed slurries containing nano-sized chemical release capsules (nano-CRC) which provide highly controlled processing and efficient planarization. Instead of the traditional mixture of solid nanoparticles and chemicals, nano-CRC based slurries consist of a core-shel…
Significance and Use 5.1 Laminates are made by bonding together two or more layers of material or materials. Their performance is often dependent on the ability of the laminate to function as a single unit. If the plies have not been properly bonded toget
Objective: The aim of this study was to assess the concentration of hepatocyte growth factor in the gingival crevicular fluid of chronic gingivitis patients. Patients and Methods: A total of twenty patients were selected and grouped as follow; group I included ten chronic gingivitis patients and Group II incl…
The US Department of Energy has announced the 2016 Small Business Innovation Research and Small Business Technology Transfer (SBIR/STTR) Phase II Release 1 grants, awarded through its Office of Energy Efficiency & Renewable Energy (EERE). The winners include three projects focused on catalysis for fuel cell and hydrog…
Abstract AK Steel Chromeshield 22 stainless steel combines the exceptional corrosion performance of a high chromium ferritic alloy with the enhanced ductility of AK Steel’s Ultra Form technology. This datasheet provides information on composition, hardness, and tensile properties. It also includes information on high…
Nuclear power has contributed almost 20% of the total amount of electricity generated in the United States over the past two decades. High capacity factors and low operating costs make nuclear power plants (NPPs) some of the most economical power generators available. Further, nuclear power remains the single largest…
In an effort to lower the interconnect time delay and address the latency problem, porous low-k dielectrics are being currently explored as a low-k BEOL dielectric. Because of low density, porous dielectrics suffer from excessive impurity diffusion and from ion electromigration when the interconnect lines are powered.…
This specification covers sinterable nuclear-grade plutonium dioxide powders obtained by the oxalate precipitation route, calcination, or any other equivalent process acceptable to the buyer. Included is plutonium dioxide of various isotopic compositions as normally prepared by in-reactor neutron irradiation of natura…
In this study, low-dielectric constant (low-k) SiOC(H) films deposited using conventional plasma-enhanced chemical vapor deposition (PECVD) by varying flow rates of the deposition precursors were investigated through various characterization techniques. The deposition precursors were DEMS and ATRP, which acted as a ne…
Significance and Use 5.1 The determination of the creep rate provides information on the behavior of sandwich constructions under constant applied force. Creep is defined as deflection under constant force over a period of time beyond the initial deformat
Recently, there has been a growing scientific and technological interest in the II-VI compound semiconductor ZnO. This is due to the wide-ranging applicable properties of ZnO such as high electron mobility, high transparency, piezoelectricity, large direct band gap around 3.4 eV, in addition to luminescence due to its…
