We present a model of Ostwald ripening of nanosized clusters and apply it to study the time evolution of metal particles attached to carbon nanotubes. The Ostwald ripening of metal clusters attached to carbon nanotubes differs from that of free metal clusters. While free clusters experience a rapid broadening in the s…
Abstract This study considers the effects of pellet geometry and compatibilization on its moisture absorption and thermal degradation behavior of recycled polyethylene terephthalate (RPET) and recycled polypropylene (RPP) blend with the ultimate goal of optimizing the design of pellets to enhance their processability.…
The selective synthesis of inorganic oxides with unique morphology has attracted considerable interest because of their morphology-dependent properties and applications. Efforts on most synthetic inorganic oxides have been focused on preparing a stable morphology rather than providing a strategy for producing various…
The structure of superconducting order parameter near the surface of a two-band superconductor with ${s}_{\ifmmode\pm\else\textpm\fi{}}$ order parameter in the bulk is theoretically investigated. The main parameter of the surface, which determines the appropriate physics, is the coefficient of the interband scattering…
In this paper we present the aggregation kinetics of single-walled carbon nanotubes (SWCNTs), when aggregated by NaBr and CaCl 2 in the solvents DMF, NMP, and 50/50 DMF/NMP (v/v). We have measured critical coagulation concentrations (CCCs) by finding the diffusion-limited aggregation regime for each salt/solvent combi…
A tenuous monolayer of hydrophobic particles at the air-water interface often forms a scum or raft. When such a monolayer is disturbed by the localized introduction of a surfactant droplet, a radially divergent surfactant shock front emanates from the surfactant origin and packs the particles into a jammed, compact, a…
Abstract The effect of crystal orientation on the microstructure of a nickel‐based crystalline superalloys during directional solidification was explored. Differently oriented crystals with [001] and [011] orientations were fabricated with seeding technique. The results showed that primary dendrite arm spacings decrea…
Nanosilica-filled water-based acrylic nanocomposites with varying monomer ratio and nanosilica content were prepared by emulsion polymerization. The resulting resins were coated on ceramic, steel, and glass substrates and the scratch resistances were measured. The relationship between the scratch resistance and the co…
Solubilities for boron-carbon-nitride (BCN) ternary alloys in their polymorphs are systematically studied using a combination of first-principles calculations and cluster expansion technique. Unlike diamond-like and graphite-like structures, we find significant anisotropy in solubility for the wurtzite-like structure,…
Recently, nanostructured silicon-based thermoelectric materials have drawn great attention owing to their excellent thermoelectric performance in the temperature range around 450 °C, which is eminently applicable for concentrated solar thermal technology. In this work, a unified nanothermodynamic model is developed to…
The scope of the present article is to study the effect of reinforcing filler loading and coupling agent treatment on long-term water uptake of wood plastic composites. Polypropylene and wood flour were compounded into hake internal mixer and the test specimens were prepared by injection molding. Three different conte…
We develop a Fermionic Chern-Simons (CS) theory for the fractional quantum Hall effect in monolayer graphene with SU(4) symmetry. We construct a general CS coupling matrix such that an even number of spin- and valley-dependent flux quanta is attached to all electrons and that any electron sees an integer number of flu…
Using vertically aligned Cu 2 S nanowires as both physical templates and chemical sources, unique heteronanostructures were synthesized by solid-state conversion reactions at low temperatures. At temperatures as low as 105 °C and in the presence of H 2 S, segmented nanowires and rod-in-a-tube (RIT) structures were pro…
Solving the inverse problem of nanoparticle characterization has the potential to advance science and benefit society. While considerable progress has been made within a framework based on the scattering of surface plasmon-polaritons, an aspect not heretofore considered is the quantification of uncertainty in the esti…
Abstract A kinetic investigation on the reduction of nanometer‐sized nickel oxide particles (supported and unsupported) with hydrogen was carried out. The reduction behavior was found to be related to the average size of NiO crystallites. When the NiO crystallite size was less than about 20 nm, the dissociation of H 2…
We present an optical spectroscopy study on singe crystalline ErTe${}_{3}$, a rare-earth-element tritelluride, which experiences two successive charge-density wave (CDW) transitions at ${T}_{c1}=267$ K and ${T}_{c2}=150$ K. Two corresponding gap features, centered at 2770 ${\mathrm{cm}}^{\ensuremath{-}1}$ ($\ensuremat…
Immobilizing a homogeneous catalyst provides obvious handling benefits, but ideally can also enhance catalyst productivity or selectivity because of beneficial interactions between the surface and the active site. Here, Mn 1,4,7-trimethyl-1,4,7-triazacyclononane dimers ( 1 ) are activated by carboxylate-containing sol…
Abstract In this study the effect of carbon nanotubes content as well as of the tensile stress level applied upon the linear viscoelastic creep response of carbon nanotube polymer nanocomposites was investigated. Experimental findings were modeled by means of the newly developed hybrid viscoelastic interphase model, w…
Abstract To study the effect of organophilic clay concentration on nonisothermal crystallization, poly( L ‐lactic acid) (PLLA)/montmorillonite (MMT) nanocomposites were prepared by mixing various amounts of commercial MMT (Cloisite ® 30B) and PLLA. The effect of MMT content on melting behavior and crystal structure of…
Based on measuring the change of the photoacoustic (PA) signal generated by laser-induced nanobubbles, a new way to detect gold nanoparticles (GNPs) aggregation is demonstrated and applied to selective protein detection.
