Abstract In this article, the combination of silicone rubber (SR) elastomer with synthetic iron montmorillonite (Fe‐MMT) to form a kind of new flame‐retardant system based on an ethylene–vinyl acetate (EVA) copolymer is first reported. Also, the flame retardancy of the EVA/SR/Fe‐MMT hybrid are compared with that of EV…
Size-tunable monodispersed hierarchical metallic Ni nanocrystals (58−190 nm in diameter) have been prepared by the reduction of Ni 2+ with hexadecylamine under atmospheric pressure. The diameter of the particles could be tuned by simply changing the reaction time. The products were characterized with X-ray powder diff…
In the present article, we proffer an explanation for the origin of single molecule magnetism in [Cu II LTb III (hfac) 2 ] 2, a member of the novel class of mixed transition−lanthanide metal clusters. The theoretical model takes into account the crystal field acting on the Tb III ion as well as the exchange interactio…
The use of Li3BN2H8 complex hydride as a practical hydrogen storage material is limited by its high desorption temperature and poor reversibility. While certain catalysts have been shown to decrease the dehydrogenation temperature, no significant improvement in reversibility has been reported thus far. In this study,…
Metamaterials with anisotropic electromagnetic properties have the capability to manipulate the polarization states of electromagnetic waves. We describe a method to design a broadband, low-loss wave retarder with graded constitutive parameter distributions based on non-resonant metamaterial elements. A structured met…
This paper reports on differences in stability of Pd hydride phases in palladium particles with various degrees of contact with microporous carbon supports. A sample containing Pd embedded in activated carbon fibre (2 wt% Pd) was compared with commercial Pd nanoparticles deposited on microporous activated carbon (3 wt…
ZnO rod arrays were successfully fabricated on fluorine-doped tin oxide substrates without seed layers and high temperature annealing. ZnO was crystallized in aqueous solutions to form hexagonal cylindrical rods on the substrates directly. The rods elongated along the c -axis and stood perpendicular to the substrates.…
The nucleation of Pb clusters on the five-fold Al-Pd-Mn quasicrystal surface has been investigated using scanning tunneling microscopy (STM) and ab initio calculations based on density-functional theory (DFT). In the submonolayer regime, Pb atoms are highly mobile and adsorb preferentially within equatorially truncate…
Fluoride glasses are the only materials that transmit light in a continuous fashion from ultraviolet up to 8 μm in the mid-infrared region, and can be drawn into high quality optical fibers. In fact fluoride glass fiber technology is the second most mature, beside silica based fiber technology. Fluoride glasses hav…
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.
