We investigated how solvent quality affects the stability of polymer-grafted nanoparticles in semidilute and concentrated polymer solutions, which extends our previous studies on these types of dispersions in good solvents [Langmuir 2008, 24, 5260-5269]. As discussed in the current article, dynamic light scattering (D…
The growth velocity of silicon ⟨110⟩ faceted dendrites as a function of the twin spacing was investigated by in situ observation. As the twin spacing increases, ⟨110⟩ dendrite growth velocity nonlinearly decreases. The theoretical ⟨110⟩ and ⟨112⟩ dendrite growth velocities were calculated on the basis of the modified…
Abstract A bifunctional silane (TESPD) was added to a vinyl‐group‐containing silicone rubber (SR)/natural rubber (NR)/silica compound, and the resulting mechanical, morphological, and thermal properties were compared with those of an NR/silica compound. The addition of TESPD to the silica‐filled SR/NR compound formed…
The angular dependent magnetoresistance (AMR) of Nd0.45Sr0.55MnO3 thin film epitaxially grown on SrTiO3 (001) is examined at different temperatures and magnetic fields. Twofold and fourfold symmetric AMR and a transition between them are observed under two different measurement modes and are found to be dependent on t…
Using density-functional theory we investigate the evolution of the magnetic ground state of ${\text{NbFe}}_{2}$ due to doping by Nb-excess and Fe-excess. We find that nonrigid-band effects due to the contribution of $\text{Fe}\text{ }d$ states to the density of states at the Fermi level are crucial to the evolution o…
Nearly half of known protein structures interact with phosphate-containing ligands, such as nucleotides and other cofactors. Many methods have been developed for the identification of metal ions-binding sites and some for bigger ligands such as carbohydrates, but none is yet available for the prediction of phosphate-b…

We have made high density amorphous ice (HDA) by the pressure-induced amorphization of hexagonal ice at 77 K and measured the volume change on isobaric heating in a pressure range between 0.1 and 1.5 GPa. The volume of HDA on heating below ∼0.35 GPa increases, while the volume of HDA on heating above ∼0.35 GPa decreas…
Abstract The effect of epoxidized natural rubber (ENR) with 50 mol% epoxidation (ENR 50) on the processing behaviors, tensile properties, morphology, and thermal properties of linear‐low‐density polyethylene (LLDPE)/soya powder blends was investigated. The LLDPE was blended with various soya powder contents in a Haake…
We report X-band electron paramagnetic resonance (EPR) and $^{125}\text{T}\text{e}$ and $^{77}\text{S}\text{e}$ NMR measurements on single-crystalline superconducting ${\text{FeSe}}_{0.42}{\text{Te}}_{0.58}$ $[{T}_{c}=11.5(1)\text{ }\text{K}]$. The data provide indications for the coexistence of intrinsic localized an…
The ground states of two types of distorted mixed diamond chains with spins 1 and 1/2 are investigated using exact diagonalization, DMRG, and mapping onto low-energy effective models. In the undistorted case, the ground state consists of an array of independent spin-1 clusters separated by singlet dimers. The lattice…
The spin-crossover system $[\text{Fe}{(\text{ptz})}_{6}]{({\text{BF}}_{4})}_{2}$ has been studied for more than 25 years and is used as a model system to the understanding of the eponymous phenomenon in solid-state materials. However, the structural properties of the low-spin phase formed at low temperature after a sl…
This paper is focused on the performance of the 1 MW plant designed and developed by Rolls-Royce Fuel Cell Systems Limited. The system consists of a two stage turbogenerator coupled with pressure vessels containing the fuel cell stack, internal reformer, cathode ejector, anode ejector, and off-gas burner. While the ov…
Polymer-based nanocomposites were prepared by solution blending of polyhedral oligomeric silsesquioxane with phenethyl substituents (PhenethylPOSS) into poly(bisphenol A carbonate) (PBAC). First investigations focused on structure, morphology and dynamics, addressed mainly by dielectric relaxation spectroscopy are sub…
We have carried out Raman and second harmonic generation (SHG) measurements to probe thermal poling-induced phenomena in glass 20Na2O-80[0.35Nb2O5-0.65GeO2]. A SHG response of 0.6 pm/V was measured after poling in a ∼3 μm thick layer under the anode and found to deviate from the widely used electric field-induced SHG…
The use of M-type barium hexagonal ferrite (BaM) thin films for self-biased planar millimeter wave notch filters was demonstrated for the first time. The BaM film was grown by pulsed laser deposition and showed a remanent to saturation magnetization ratio of 0.99 and a 60 GHz ferromagnetic resonance linewidth of about…
Abstract Two kinds of PS microspheres with different structures are prepared in one reaction system via Pickering emulsion polymerization. As the stabilizer, titania nanoparticles are modified by oleic acid or sodium oleate and then investigated using aqueous electrophoresis measurements, DLS and oil/water partitionin…
Abstract The nucleating effect of zinc phenylphosphonate (PPZn) was investigated on the as‐bacterially synthesized poly(3‐hydroxybutyrate) [P(3HB)] and poly[(3‐hydroxybutyrate)‐ co ‐(3‐hydroxyhexanoate)]s [P(3HB ‐co‐ 3HHx)s] in order to improve their crystallization rate. PPZn is found an efficient nucleating agent on…
Extracellular matrix (ECM), like biomimetic surface modification of titanium implants, is a promising method for improving its biocompatibility. In this paper chitosan (Chi) and heparin (Hep) multilayer was coated on pure titanium using a layer-by-layer (LbL) self-assembly technique. The Hep-Chi multilayer growth was…
