A DFT Computation for Comparison of NQR of O2, N2 and CO over the Surface of Single-Walled Carbon Nanotubes
In this study we assumed Single-Walled Carbon Nano Tubes (SWCNTs) as ideal candidates for various applications of gas sensors due to their amazing physical adsorption properties. The adsorption behavior of selected nitrogen, oxygen and CO molecules on the surface of the Single-Walled Carbon Nano Tubes (SWCNTs) was stu…
Self-assembly of a 3-D self-catenated framework based on [V4O12]4−polyoxoanions and cobalt-organic polymer
Reaction of a flexible ligand with cobalt salt in the presence of polyoxovanadate produces a new composite solid, Co2(btx)4V4O12, 1 (btx = 1,4-bis(triazol-1-ylmethyl)benzene). The structure of 1 was determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis, IR spectrum, an…
Microstructure of anatase-based hybrid nanocomposites
Morphology, crystalline arrangement and stoichiometry of f-CNTs/TiO 2 /Pt nanohybrids are systematically investigated as a function of TiO 2 content (28–93 wt%). The results show that TiO 2 content plays a relevant role in determining the chemical/morphological properties of the investigated nanohybrids. Significant c…
Syntheses, Structure, Photoluminescent, and Thermal Properties of a Novel Coordination Polymer [CuI(4-bpfob)(HCN)(DMF)]n With One-Dimensional Helical Chain
Solution reaction of CuI and the ligand 4-bpfob [4-bpfob = N,N′-(1,2-phenylene)diisonicotinamide] led to the formation of a novel coordination polymer [CuI(4-bpfob)(HCN)(DMF)]n that exhibited an unusual one-dimensional helical structure. The compound was characterized by X-ray crystallography, infrared spectroscopy, f…
Vapor Films under Influence of High Heat Fluxes: Nongravity Surface Waves and Film Explosive Disintegration
Abstract Linear and non-linear stability analysis of the interface between a thin vapor film and a layer of liquid in the presence of a steady heat flux from a metal surface heated to a high temperature, to the vapor film and then from vapor to the subcooled liquid is investigated. The temperature dependence of satura…
Differences in crystallization of two LinB variants fromSphingobium japonicumUT26
Haloalkane dehalogenases are microbial enzymes that convert a broad range of halogenated aliphatic compounds to their corresponding alcohols by the hydrolytic mechanism. These enzymes play an important role in the biodegradation of various environmental pollutants. Haloalkane dehalogenase LinB isolated from a soil bac…
Large-Area Patterning of the Tackiness of a Nanocomposite Adhesive by Sintering of Nanoparticles under IR Radiation
We present a simple technique to switch off the tack adhesion in selected areas of a colloidal nanocomposite adhesive. It is made from a blend of soft colloidal polymer particles and hard copolymer nanoparticles. In regions that are exposed to IR radiation, the nanoparticles sinter together to form a percolating skele…
Oxidation of Alcohols and Pyridines by a Water-Soluble Polyoxometalate with Hydrogen Peroxide
A water-soluble catalyst based on a silicotungstate polyoxometalate, K8[β-SiW11O39] · 14H2O, was developed for the oxidation of pyridines and alcohols with hydrogen peroxide. The reactions were carried out in water, and good yields of the corresponding heterocyclic N-oxides and ketones were obtained under relatively m…
Doping Characteristics of Polycrystalline Silicon Deposited by Chemical Transport at Atmospheric Pressure and its Application to MEMS Sensor
This paper reports the doping properties of polycrystalline silicon (poly-Si) deposited by atmospheric pressure plasma enhanced chemical transport and its application to a piezo-resistive pressure sensor. The doping is done by the chemical transport of dopants in Si sources. The structural and electronic properties re…
Determination of onset of plasticity (yielding) and comparison of local mechanical properties of friction stir welded aluminum alloys using the micro‐ and nano‐indentation techniques
Purpose The purpose of this paper is to determine if the nanoindentation technique is a reliable method and whether it can be used to measure the surface hardness (H) in friction stir welded aluminum alloys. In order to test the reliability of nanoindentation technique, nanohardness values for friction stir welded alu…
Application of Thin‐Film Manufacturing Technologies to Solid Oxide Fuel Cells and Gas Separation Membranes
The implementation of thin‐film technologies in energy‐related applications, such as special fuel cells and gas separation membranes for low‐emission power plants, is essential in terms of enhancing the functionality, reducing operating temperatures, and increasing lifetime. Introducing thin electrolyte layers into so…
Enhanced ferromagnetism by adding electrons in triple-decker Gd–phthalocyanine
The electronic structures and magnetic properties of triple-decker Gd–phthalocyanine have been studied by using the HSE06 hybrid function method. The results show that triple-decker Gd–phthalocyanine is a small band gap semiconductor. Ferromagnetic coupling is unstable in neutral triple-decker Gd–phthalocyanine due to…
Spectroscopic Identification of Surface Intermediates in the Dehydrogenation of Ethylamine on Pt(111)
Reflection absorption infrared spectroscopy, temperature-programmed desorption, and density functional theory (DFT) have been used to study the surface chemistry and thermal decomposition of ethylamine (CH 3 CH 2 NH 2 ) on Pt(111). Ethylamine adsorbs molecularly at 85 K, is stable up to 300 K, and is partially dehydro…

Spectroscopic ellipsometry study of novel nanostructured transparent conducting oxide structures
Spectroscopic ellipsometry has been used to find the optical constants, including refractive index, extinction coefficient, thickness and volume fraction of nanostructured transparent conducting oxides including indium tin oxide (ITO) and indium zinc oxide (IZO). We observed sharp features in the ellipsometry data, wi…

Expression, purification, crystallization and preliminary X-ray diffraction analysis of a lactococcal bacteriophage small terminase subunit
Terminases are enzymes that are required for the insertion of a single viral genome into the interior of a viral procapsid by a process referred to as 'encapsulation or packaging'. Many double-stranded DNA viruses such as bacteriophages T3, T4, T7, λ and SPP1, as well as herpes viruses, utilize terminase enzymes for t…
