We report the simultaneous and selective synthesis of single-crystalline Co(n)Si NWs (n = 1-3) and their corresponding crystal structures--simple cubic (CoSi), orthorhombic (Co(2)Si), and face-centered cubic (Co(3)Si)--following a composition change. Co(n)Si NWs were synthesized by placing the sapphire substrates alon…
Guo suggests that the reported ionic conductivity of ZrO 2 :Y 2 O 3 /SrTiO 3 heterostructures might be due to the electronic conductivity from the SrTiO 3 . We point out shortcomings in his reasoning and underscore that our results show that any electronic contribution to the conductance is at least three orders of ma…
The reaction system Mn/Sn/S/hydrazine/water at approximately 150 degrees C afforded [Mn(2)SnS(4)(N(2)H(4))(2)] (1). The compound has a unique neutral three-dimensional framework with bridging hydrazine ligands and a variety of interconnectivity modes between MnL(6) (L = N, S) octahedra. The complex structure of 1 lead…
Photoelectrochemical behavior of self-assembled C 60 via axial coordination to an electrochemically polymerized zinc porphyrin film was systematically investigated to unravel the importance of the coordinated fullerene in improving the photocurrent and photovoltage generation of the resulting donor−acceptor dyad. For…
This paper presents the results of combined investigation of the chemical bond formation in fluorinated multiwalled carbon nanotubes (MWCNTs) with different fluorine contents $(10--55\text{ }\text{wt}\text{ }%)$ and reference compounds (highly oriented pyrolytic graphite crystals and ``white'' graphite fluoride) using…
Recent advances in statistical procedures, coupled with the availability of high performance computational resources and the large mass of data generated from high throughput screening, have enabled a new paradigm for building mathematical models of the kinetic behavior of catalytic reactions. A Bayesian approach is u…
Reactive hydride composites (RHCs) are very promising hydrogen storage materials for future applications due to their reduced reaction enthalpies and high gravimetric capacities. At present, the materials' functionality is limited by the reaction kinetics. A significant positive influence can be observed with addition…

We report molecular dynamics simulations of tensile elongation of carbon nanotubes (CNTs) over a wide temperature range. In particular, we examine temperature and size effects on tensile ductility of CNTs and compare our results with recent experimental observation on superplastic deformation of CNTs at high temperatu…
This paper describes a structure-property study of mixed self-assembled monolayers (SAMs) on gold that present methylated or hydroxyl-terminated polyglycerol (PG) structures that vary in size and architecture, and their ability to resist the adsorption of four test proteins from solution. Mixed SAMs were prepared by t…
Binary-phased PbTe-PtTe2 nanoparticles are synthesized by co-precipitation in a chemical process. These nanoparticles show much enhanced power factors as compared to that of pure PbTe nanoparticles, which may give impact on development of new types of highly efficient thermoelectric materials.
Hydrophilic titania (TiO(2)) nanoparticles were dispersed in solutions of polystyrene (PS), and the suspensions were cast on glass surfaces. The effect of drying temperature on the hydrophobic character of PS/TiO(2) was investigated: the static water contact angle increased with the drying temperature, and the as-prep…
We report on radiative decay rate modifications of dipole emitters in the proximity of anisotropic metal nanostructures. Using time, angle, and polarization resolved photoluminescence spectroscopy, we show that resonant interactions between surface plasmons in gold nanodisks and excitons in semiconductor nanocrystals…
We simulate the electron transmission through insulating Mylar (polyethylene terephthalate, or PET) capillaries. We show that the mechanisms underlying the recently discovered electron guiding are fundamentally different from those for ion guiding. Quantum reflection and multiple near-forward scattering rather than th…
Density functional modeling of the crystalline layered aluminosilicate mineral kaolinite is conducted, first to reconcile discrepancies in the literature regarding the exact geometry of the inner and inner surface hydroxyl groups, and second to investigate the performance of selected exchange-correlation functionals i…
The hydrogen adsorption on alkaline-earth metal dispersed in doped graphenes was studied through ab initio calculations. Substitutional doping in graphenes is explored to control the ionic state of the metal atoms that plays a crucial role for dispersion and hydrogen adsorption. It was found that the adsorption behavi…
Copper is selected as a conductive filler to produce copper core yarns to make woven fabric using a network analyser equipment, and the electromagnetic shielding effectiveness of these fabrics is measured in the frequency range of 20–18,000 MHz. With an increase in the number of conductive fabric layers, finer yarn co…
Nanoparticles of MgH2 incorporated in a mesoporous carbon aerogel demonstrated accelerated hydrogen exchange kinetics but no thermodynamic change in the equilibrium hydrogen pressure. Aerogels contained pores from <2 to approximately 30 nm in diameter with a peak at 13 nm in the pore size distribution. Nanoscale MgH2…
Green rust, a family of Fe(II), Fe(III) layered double hydroxides, is believed to be present in environments close to the Fe(II)/ Fe(III) transition zone. Attempts to identify members of this family in nature have proven difficult because the material is oxidized after only a few minutes exposure to air. In this paper…
Experimental and theoretical studies on Mg(BH4)2 were carried out from the viewpoint of the formation of the intermediate compound MgB12H12 with B12H12 cluster. The full dehydriding and partial rehydriding reactions of Mg(BH4)2 occurred according to the following multistep reaction: Mg(BH4)2 -->1/6MgB12H12 + 5/6MgH2 +…
