A ‘bottom-up’ approach is utilized for assembling magnetic nanoparticles in a mesoporous silica solid for the generation of a magnetic nanocomposite. Grafting of a palladium complex of the type (L)2PdCl2 (L=Si(OMe)3 functionalized PPh3) results in an active, recyclable catalyst for CC coupling reactions.
The kinetics for NO reduction over supported platinum under lean condition were investigated by first-principles-based kinetic Monte Carlo simulation over three-dimensional Pt nanoparticles. Model platinum nanoparticles with diameters ranging from 2.3 to 4.6 nm were constructed using a truncated octahedral cluster con…
Abstract In recent years, the interest for using biogas derived from biomass as fuel in solid oxide fuel cells (SOFCs) has increased. To maximise the biogas to electrical energy output, it is important to study the effects of the main biogas components (CH 4 and CO 2 ), minor ones and traces (e.g. H 2 S) on performanc…
Abstract The dielectric properties of polyurethane (PUR) latex–boehmite alumina nanocomposites were investigated by means of broadband dielectric spectroscopy in the temperature range −100 °C to 70 °C. The concentration of the filler (alumina) was kept constant at 10 phr for all specimens, whereas the mean particle di…
To evaluate the feasibility of a strategy to partially replace polyamide-6 (PA6) with poly(lactic acid) (PLA), the morphology, mechanical, and thermal properties of PA6/PLA blending systems were investigated. Polyethylene-octene elastomer (POE) and POE grafted with maleic anhydride (POE-g-MAH) are added to improve the…
We developed a novel one-pot polyol approach for the synthesis of biocompatible CdSe quantum dots (QDs) using poly(acrylic acid) (PAA) as a capping ligand at 240°C. The morphological and structural characterization confirmed the formation of biocompatible and monodisperse CdSe QDs with several nanometers in size. The…
In this study, electromagnetic shielding effectiveness of some weft‐knitted structures is investigated. For this purpose, weft‐knitted structures are produced using copper wire/cotton incorporated yarns. Conductive yarns are produced by yarn‐folding machine. Four knitted constructions (plain knitting, weft in‐laid pla…
The inelastic light scattering spectrum of $\text{Pb}[{({\text{Mg}}_{1/3}{\text{Nb}}_{2/3})}_{1\ensuremath{-}x}{\text{Ti}}_{x}]{\text{O}}_{3}$ $(\text{PMN-}x\text{PT})$ single crystals with $x=0--0.55$ due to longitudinal-acoustic (LA) waves was investigated in a wide temperature range by using a Brillouin scattering…
In our prior studies, we reported the growth of Co 3 O 4 nanowire arrays via the ammonia-evaporation-induced growth in solution and their promising applications in a Li-ion battery and oxygen evolution. Although we had identified that the growth of Co 3 O 4 nanowire went through the β-Co(OH) 2 intermediate, the growth…
Large and high quality single crystals of the new unconventional superconductor LiFeAs were grown by a new approach using the self-flux technique. Both energy dispersive X-ray spectroscopy and inductively coupled plasma mass spectroscopy revealed a stoichiometric Li/Fe/As composition. Measurements of the magnetic susc…
Co-doped In 2 O 3 nanocrystals showing room-temperature ferromagnetism have been successfully prepared by a simple sol−gel synthesis route. The sample displays a clear ferromagnetism behavior above 300 K. Phase and structure analyses reveal that the nanocrystals are crystallized with Co ions substituted for In ions in…
We demonstrate in this article the facile synthesis of a novel range of “treelike” polyethylene block polymers constructed uniquely with chain blocks of hybrid hyperbranched−linear chain topologies from sole ethylene stock. Though chemically identical, the blocks in the polymers are featured with distinctly different…
Methyl substituted seven-membered ring carbonates (7CCs), namely, 4-methyl- and 5-methyl-1,3-dioxepan-2-one (α-Me7CC and β-Me7CC), have been synthesized in high yields (up to 70%) upon cyclization of the corresponding α,ω-diols issued from green renewable acids. (“Immortal”) ring-opening polymerization of these monome…
Novel high-κ thin composite films with excellent breakdown strength were synthesized using nonhydrolytic sol−gel processing. Organic−inorganic hybrid materials with high electronic polarizability were prepared as the matrix material to form a covalently bonded interface with the organically modified barium titanate (T…
This paper focuses on the production of electricity using a thermoelectric generator placed on the human body connected to a dc-dc converter. The small difference in temperature between the hot heat source (e.g. the human body, Tb = 37 °C) and the cold heat source (e.g. ambient air, Ta = 22 °C), associated with a poor…
We developed a computer-aided rational solvent selection procedure for improving the morphology of needle-like crystals and applied it to 2,6-dihydroxybenzoic acid (DHB) form 2 crystals. In our procedure, a simple morphology prediction model, the Bravais−Friedel−Donnay−Harker (BFDH) model, was first applied to identif…
Molecular dynamics simulations are performed on capped and uncapped PbSe nanocrystals, employing newly developed classical interaction potentials. Here, we show that two uncapped nanocrystals fuse efficiently via direct surface attachment, even if they are initially misaligned. In sharp contrast to the general belief,…

We investigate the structural, electronic, and vibrational properties of graphene nanoflakes (GNFs) with a small number of atoms (<250) and distinct shapes (triangular, rectangular, and hexagonal) through classical molecular dynamics (CMD) and density functional theory (DFT) calculations. We show that these graphene n…
This article explores the transverse thermal conductance between two parallel—bonded as well as nonbonded—carbon nanotubes, embedded in an epoxy matrix using nonequilibrium molecular dynamics simulations. Here, we study the effect of different organic linkers—connecting the two nanotubes—on the thermal interface condu…
