Graphene is only one atom thick, optically transparent, chemically inert, and an excellent conductor. These properties seem to make this material an excellent candidate for applications in various photonic devices that require conducting but transparent thin films. In this letter, we demonstrate liquid crystal devices…
Inorganic molecules (ions) and ligands are classified into diatomic, triatomic, four-atomic, five-atomic, six-atomic, and seven-atomic types, and their normal modes of vibration are illustrated and the corresponding vibrational frequencies are listed for each type. Molecules of other types are grouped into compounds o…
We investigate the effect of substituting Si for Ge in the ferromagnetic superconductor UCoGe. dc-magnetization, ac-susceptibility, and electrical resistivity measurements on polycrystalline $\mathrm{U}\mathrm{Co}{\mathrm{Ge}}_{1\ensuremath{-}x}{\mathrm{Si}}_{x}$ samples show that ferromagnetic order and superconducti…
A novel fabrication technique, a combination of slurry dipping and electrospraying, was used to produce hydroxyapatite foams as potential matrices for bone tissue engineering applications. In this study, scaffolds that were slurry dipped and electrosprayed for different time intervals were compared with foams prepared…
In2S3 thin films containing different quantities of sodium have been synthesized by co-evaporation of sodium and In2S3 powder from separate sources using vacuum thermal evaporation method. Films were deposited on ordinary glass at 240 °C. The process of incorporation of sodium was studied as function of at.% Na. Films…
We present an atomic scale quantum-mechanical theory based on a noncollinear tight-binding formalism for self-consistent calculations of electronic and magnetic structures of $d$-metallic systems in an external magnetic field. The theory is applied to the description of the magnetic reversal process in exchange-spring…
From manufacturing to medicine, nanotechnology implies revolutionary change. However, the sweeping changes wrought by a technological advance of this magnitude are likely to come at a price that includes unforeseen environmental impact, disruptions in industry, displacement of workers, and deeply controversial applica…
In this work, we investigated the influence of polarization effects on the electronic excitation of the $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{a}\text{ }{^{3}B}_{1u}$ state of ethylene. We employed the Schwinger multichannel method implemented with pseudopotentials to compute the elastic and the inelastic scatte…
We have used density functional theory within spin-polarized local density approximation to investigate the equilibrium structure, electronic, and magnetic properties of one-dimensional Ni/Cu and Ni/Al multilayered nanowires. In particular, we look into the subtle changes in the magnetic properties of the nanowires wi…
In the present study, we have used a combination of 2-DE and MS to isolate and characterize two variants of the mitochondrial complex I subunit NDUFA10 from Wistar rat brain. Extensive MS/MS analysis revealed that a D/N substitution at position 120 resulting from a 353A/G transition in the coding gene is the biochemic…
The anaerobic lifestyle of the intestinal parasite Blastocystis raises questions about the biochemistry and function of its mitochondria-like organelles. We have characterized the Blastocystis succinyl-CoA synthetase (SCS), a tricarboxylic acid cycle enzyme that conserves energy by substrate-level phosphorylation. We…
Here, we report the first synthesis of TiO 2 −B@C core−shell nanoribbons by a simple hydrothermal route. The as-prepared single-crystalline TiO 2 −B nanoribbon cores are up to tens of micrometers in length and 50−200 nm in width. The nanoribbons are sheathed with a thin layer of carbon. The possible formation mechanis…
The present paper investigates the wettability–microstructure–mechanical property relationships in wide gap transient liquid phase (TLP) bonds between the single crystal nickel base superalloy CMSX-4 and two polycrystalline superalloys, IN 738 and IN 939, using wide gap style composite interlayers Niflex-110 and Nifle…
An undiluted exhaust hydrocarbon (HC) speciation method, using flame ionization detector gas chromatographs, is developed to investigate HC species from conventional and low-temperature premixed charge compression ignition (PCI) combustion pre- and postdiesel oxidation catalyst (DOC) exhaust. This paper expands on pre…
We report the demonstration of waveguided germanium-on-silicon-on-insulator metal-semiconductor-metal (MSM) photodetectors with novel silicon-carbon (Si:C) Schottky barrier enhancement layer. Significant suppression of dark current (/dark) by ~4 orders of magnitude was achieved over a conventional MSM photodetector du…
High level ab initio computations in vacuum and with the IEFPCM implicit solvent model are carried out on 5-(hydroxymethyl)tetrahydropyran to investigate the effects of water on the exocyclic torsional surface. Rotamer populations evaluated from the omega(C-C-C-O), theta(C-C-C-O) solvent surface agree almost quantitat…

The literature on artificial receptors that recognize catecholamines in aqueous solution is reviewed. Although the substrates offer a number of potential sites for molecular recognition, the solvent constrains the range of possible pair-wise interactions that can be utilized. As a result, the dual goal of strong bindi…
This paper deals with the measurement of the interfacial stress of a composite beam using an embedded piezoelectric PVDF (polyvinylidene-fluoride) strip. The composite beam consists of an aluminium beam on which an ice layer is deposited. The ice layer is formed from sprayed supercooled water droplets, simulating atmo…
