A fluid constituted of hard spherocylinders is studied using a density functional theory for non-spherical hard particles, which can be written as a function of weighted densities. This is based on an extended deconvolution of the Mayer f-function for arbitrarily shaped convex hard bodies in tensorial weight functions…
We propose that embedding silicon nanoparticles (NP) into amorphous, nonstoichiometric ZnS leads to promising nanocomposites for solar energy conversion. Using ab initio molecular dynamics simulations we show that, upon high temperature amorphization of the host chalcogenide, sulfur atoms are drawn to the NP surface.…
The effect of simultaneous addition of multiwall carbon nanotubes (MWNTs) and a reactive compatibilizer (styrene maleic anhydride copolymer, SMA) during melt‐mixing on the phase morphology of 80/20 (wt/wt) PA6/ABS blend has been investigated. Morphological analysis through scanning and transmission electron microscopi…
Graphene free-standing film-like or paper-like materials have attracted great attention due to their intriguing electronic, optical and mechanical properties and potential application in chemical filters, molecular storage and supercapacitors. Although significant progress has been made in fabricating graphene films o…
The presence of a metal nanoparticle (MNP) near a quantum dipole emitter, when a localized surface plasmon mode is excited via the resonant coupling with an excited quantum dipole, dramatically changes the relaxation dynamics: an exponential decay changes to step-like behavior. The main physical consequence of this re…
Band structure calculations that incorporate impurity effects suggest that a band resonant state may be formed in p-type CoSb3-based skutterudites by replacing Sb atoms with Sn dopant atoms. Such resonant states have the potential to greatly improve thermoelectric energy conversion efficiency by increasing the density…
Molecular details of glycine adsorbed on mesoporous MCM-41 silica surfaces were determined, and their comparison to binding onto SBA-15 surfaces provided a correlation between surface structure and reactivity. Employing solid-state NMR techniques, the interfacial interactions and structural and dynamic states of surfa…
The functionalized catecholate, tetraethyl (2,3-dihydroxy-1,4-phenylene)bis(phosphonate) (H2 -DPC), has been used to prepare a series of lithium salts Li[B(DPC)(oxalato)], Li[B(DPC)2], Li[B(DPC)F2], and Li[P(DPC)3]. The phosphoryl-rich character of these anions was designed to impart flame-retardant properties for the…
We investigated the effects of phosphorus substitution on the shape of the ${T}_{c}(x)$ dome in 1111-type ${\mathrm{SmFeAs}}_{1\ensuremath{-}y}{\mathrm{P}}_{y}{\mathrm{O}}_{1\ensuremath{-}x}{\mathrm{H}}_{x}$ $(0\phantom{\rule{0.16em}{0ex}}<\phantom{\rule{0.16em}{0ex}}x\phantom{\rule{0.16em}{0ex}}<\phantom{\rule{…
Two-phase dendrites are needlelike crystals with a eutectic internal structure growing during solidification of ternary alloys. We present a scaling theory of these objects based on Ivantsov's theory of dendritic growth and the Jackson-Hunt theory of eutectic growth. The additional introduction of the relationship $\e…
OBJECTIVE: This study was designed to evaluate the dialysability of gadoteric acid in patients with end-stage renal disease (ESRD) requiring hemodialysis. Gadoteric acid is used for magnetic resonance imaging. It is cleared from the blood exclusively by glomerular filtration. In an attempt to decrease the occurrence o…
The main functions of the exhaust pumping system of a Deuterium-Tritium (DT) fusion device are to pump out the helium ash and control the divertor neutral gas density. This requires the handling of large gas throughputs at high pumping speeds (but at relatively moderate vacua). The pumped exhaust gas is then usually t…
Abstract Palladium nanoparticles dispersed in ammonium salts of hyperbranched polystyrenes are adhesively immobilized on the surface of cotton or filter papers by simply heating with dicarboxylic acids or halide anions. The resulting Pd@cotton and Pd@filter paper behave as reusable catalysts; in particular, Pd@filter…
The synthesis of silicon nanosheets (SiNSs) without using conventional vacuum processes and vapor deposition is challenging and is anticipated to receive significant attention for a wide range of applications. Thereby, mass production of silicon nanosheets with low cost can be achieved using top-down approach starting…
Abstract We report on the heterobimetallic complexes {Cu + –Co 3+ –Cu + } ( 3 ), {Cu + –Fe 3+ –Cu + } ( 4 ), {Cu 2+ –Co 3+ –Cu 2+ } ( 5 ), and {Cu 2+ –Fe 3+ –Cu 2+ } ( 6 ) and show their catalytic applications in the oxidation of hindered phenols and the oxidative coupling of terminal alkynes. The former reaction prod…
Abstract The shape sensitivity of Pd catalysts in Suzuki–Miyaura coupling reactions is studied using nanocrystals enclosed by well‐defined surface facets. The catalytic performance of Pd nanocrystals with cubic, cuboctahedral and octahedral morphologies are compared. Superior catalytic reactivity is observed for Pd NC…
In the present work, multicolor-emitting phosphors SrMg 2 La 2 W 2 O 12 :RE 3+ (RE = Tb, Sm, Tm) prepared by the solid-state reaction method were reported as interesting down-conversion luminescent materials for white light-emitting diodes and displays. The structural and bonding information understood by XRD and FTIR…
Abstract The ability to reversibly control protein structure and function with light would offer high spatiotemporal resolution for investigating biological processes. To confer photoresponsiveness on general proteins, we genetically incorporated a set of photoswitchable click amino acids (PSCaas), which contain both…
A precisely controlled destabilization of gold thiolate clusters is demonstrated to grow 12 {110}-faceted gold dodecahedra with greatly enhanced catalytic capability, and reveal the growth mechanism by DFT simulations. This greatly advances our understanding of nanocrystal growth and opens a new window for controlling…
A green and novel method for the synthesis of chiral conducting polyaniline was developed. Chiral polyaniline induced by protein was obtained by using the template-assisted polymerization route. The experimental results demonstrated that proteins such as bovine hemoglobin and bovine serum albumin had the capacity to d…
