The limiting cause of nanoconfinement of rubber molecules for their selective adsorption onto filler surface has been examined by changing: (1) the void size of carbon black aggregates, (2) the atomic scale roughness and chemical character of carbon black surface, and (3) the kind of filler from carbon black to silica…

This article deals with a simulation-based study of the impact of projectiles on thin aluminium plates using LS-DYNA by modelling plates with shell elements and projectiles with solid elements. In order to establish the required modelling criterion in terms of element size for aluminium plates, a convergence study of…

Crystal structures of triglycine selenate (TGSe) and triglycine sulfate (TGS) obtained from single crystal neutron diffraction are compared. The double well single cell local potential experienced by the non-planar amino group of one of the three glycine ions (GI) of these two isostructural crystals is obtained using…

We report on the adsorption of Mn(12) single-molecule magnets bearing external biphenyl groups on Au(111) surfaces after a simple dipping procedure. Topographic AFM images confirm that the biphenyl groups favor the adsorption of the molecules without the need of functionalization with thiols or thioether groups. The f…

Abstract We demonstrate the fabrication of thin silica‐coated CdSe/ZnS colloidal quantum dots using a reverse microemulsion method. Spherical particles of <20 nm diameter with a single dot in the centre of a thin silica shell of good morphology are achieved, promising for biophotonic applications where hydrophilic…

The dielectric response of 65Pb(Mg1/3Nb2/3)O3–35PbTiO3 (PMN-35PT) single crystals is reported for ac field amplitudes up to ∼3.5 kV/cm over a frequency range from 3 Hz to 1 kHz. The nonlinear dielectric response is described by a Rayleigh-like analysis, indicating extrinsic contributions from nonlinear and hysteretic…

Ultrahigh-transmittance conducting films (UHTCFs) of single-walled carbon-nanotubes (SWNTs) are prepared by combined direct-synthesis and solution-based methods. Perfect two-dimensional SWNT TCFs (P2DTCFs) act as “bones” and SWNT bundles as “muscles” that fill in the uncovered areas (see picture). The sheet resistance…

Abstract We report our results of continuous illumination of Ge 46 S 54 chalcogenide glass films with bandgap light in air. The outcome of this process is the formation of Ge–S backbone depleted in germanium. We relate this to consumption of some of the germanium available in the initial material due to the occurrence…

The structure and dynamics of superionic α-CuI are studied in detail by means of ab initio Born-Oppenheimer molecular dynamics simulations. The extreme cation disorder and a soft immobile face centred cubic sublattice are evident from the highly diffuse atomic density profiles. The Cu-Cu pair distribution function and…

Functionalizing and controlling nanostructures resulting from block copolymer self-assembly are key factors in defining their application. In this work, a simple but quite general route to achieve both goals simultaneously is discussed. In thin films of polystyrene-block-poly(vinyl pyridine) (PS-b-PVP) with small conc…

The chemical modification of polyamide66 (PA66) membrane by graft polymerization with methacrylic acid (MAA) was initiated under ultraviolet light. Subsequently, covalent immobilization of bioactive surface was obtained by coupling gelatin to the MAA graft chains with the aid of a water-soluble carbodiimide (WSC). The…

Abstract The first synthesis of anisotropic liquid‐crystalline colloids in silicone oil by a direct (radical) polymerization of a monomer in THF/silicone oil mixtures with the help of siloxane containing stabilizers is described. The size of the colloids is in the lower µm range and can be adjusted by varying the mixt…

The first two peaks of the optical extinction spectrum of PbSe nanocrystals in solution have been assigned in the literature to the $1{\text{S}}_{\text{h}}1{\text{S}}_{\text{e}}$ and $1{\text{P}}_{\text{h}}1{\text{P}}_{\text{e}}$ transitions. In the present work we assign the transitions causing extinction in the ener…

Current methods for measuring collagen content in engineered tissues are incompatible with monitoring of collagen production because they require destruction of the tissue. We have implemented a luciferase-based strategy to monitor collagen production noninvasively. Fibrin-based tissue constructs made using vascular s…
