A detailed wavelength-scanned surface-enhanced Raman excitation spectroscopy (WS SERES) study of benzenethiol adsorbed on Ag nanoparticle arrays, fabricated by nanosphere lithography (NSL), is presented. These NSL-derived Ag nanoparticle array surfaces are both structurally well-characterized and extremely uniform in…
Abstract The Reedijk-1 gas well was completed in 1992 with 3 ½" Carbon Steel (CS) tubing and taken into production early 2003 with a capacity of 1.8 mln Nm³/d. Due to the CO2 content, continuous corrosion inhibition was required. However as a result of operational problems it took about 9 months before injection was e…
Abstract Emulsion paper–plastic nanometer laminating adhesive of 1.5% organic montmorillonite (OMMT) was prepared by OMMT intercalating polyacrylate‐system materials. In this article, it was discovered that nanometer‐laminating adhesive has better adhesion, smaller latex particles size, lower surface tension, and high…
The optical rotation (OR) of CsLiB 6 O 10 (CLBO, space group I\bar{4}2d) along the a axis has been determined by the HAUP method [Kobayashi & Uesu (1983). J Appl. Cryst. 16 , 204–211] at a wavelength of 632.8 nm and by the TILTER method [Kaminsky & Glazer (1996). Ferroelectrics , 183 , 133–141] at 532 nm and 6…
We review the structural and hyperfine properties of Si dangling bond defects occurring in amorphous SiO 2 and at various Si–SiO 2 interfaces. These defects have in common a singly occupied orbital on a trivalent Si centre. We first briefly summarize the most important methodologies for calculating hyperfine parameter…
NO can be removed from exhaust gas streams by using a basic solution of cobalt ethylenediamine (en = H 2 NCH 2 CH 2 NH 2 ). The cobalt ethylenediamine acts as a homogeneous catalyst to oxidize NO into soluble nitric dioxide and realize the oxidation and absorption of nitric oxide simultaneously. The dissolved oxygen i…
The frequency distributions of monoclinic crystals as a function of the lattice-parameter ratios resemble the corresponding ones of orthorhombic crystals: an exponential component, with more or less pronounced sharp peaks, with in general the most important peak at the ratio value 1. In addition, the distribution as a…
Plated high saturation magnetization soft magnetic FeCo films were annealed in magnetic field; their stress, microstructure, and magnetic properties were investigated. The FeCo films consistently showed a reduced tensile stress after magnetic annealing at temperatures above 255°C. The annealing temperature was found t…
Stable Mg x Zn 1− x O solid solutions (0.32≤ x ≤0.67) with a rock salt structure were synthesized at temperatures higher than 700 °C and pressures above 5 GPa. The lattice parameters and the Mg/Zn ratio were determined by the Rietveld method from the powder x-ray diffraction data. Raman scattering studies confirmed th…
The crystal structure of the solid phase of the dipolar aprotic solvent gamma-butyrolactone (BL1), C(4)H(6)O(2), has been solved using the atom-atom potential method and Rietveld-refined against powder diffraction data collected at T = 180 K with a curved position-sensitive detector (INEL CPS120) using Debye-Scherrer…
Abstract High‐density polyethylene was functionalized using a thermolysis method in the presence of functionalized peroxides at different temperatures and at various peroxide concentrations. It was found that both percentage cross‐linking (% CL) and percentage functionalization (% Fn) increased with an increase in per…
Cu(3)Bi(2)S(3)I(3) was crystallized during an attempt to synthesize Cu-Pb-Bi sulfosalts with iodine as the transport medium. The crystal structure was solved from a black needle-like crystal on a four-circle diffractometer with a CCD detector. The solution was obtained by direct methods and subsequent difference-Fouri…
Abstract High‐density polyethylene was thermolysed with short‐chain organic compounds (additives) with an ester functional group in the presence of free radical initiator such as dicumyl peroxide at 160°C. The experimental results inferred that an additive with a hydrogen donor containing a thiol group showed better e…
Abstract Endoscopic palliation for the obstructive jaundice caused by biliary or pancreatic malignant tumors is a commonly used medical treatment. However, plastic biliary stents are occluded by sludge deposition caused by bacterial adhesion in 3–5 months. Chitosan, which has both good biocompatibility and antimicrobi…
The goal of this work was to investigate the dynamics of human plasma fibronectin (HFN) at the oil-water interface and to characterize its interactions with human serum albumin (HSA) by total internal reflection fluorescence microscopy (TIRFM). Among key results, we observed that fibronectin adsorption at the oil-wate…
Abstract The growth of silicon macropores under high current densities and high HF concentrations is studied. A new growth mode for porous Si has been found where pores resemble the so‐called current line oriented pores previously discovered in InP. For the achievement of that the electrolyte had to be optimized in re…
Abstract Reactive mineral powders were prepared with a vinyl monomer as an intercalating agent, which was grafted onto the surface of nanoclay layers, to offer crosslinking points between the nanoclay layers. According to IR characterization, the vinyl group of (3‐acrylamidopropyl)trimethylammonium chloride, grafted o…
Laterally structured hybrid assemblies composed of genetically engineered polypeptides and fused-ring organic molecules were used to guide the assembly of gold nanoparticles in a site-selective fashion (see image). Gold-binding protein was covalently bonded onto a self-assembled monolayer of preformed, π-conjugated th…
The superstructure recently discovered in [Fe(pic) 3 ]Cl 2 .EtOH at temperatures inside the step region of the high-spin–low-spin transition curve sheds new light on the anomalous transition behaviour in spin crossover compounds. The structure of the metastable LIESST state of [Fe(pic) 3 ]Cl 2 .EtOH at 10 K has been m…
Abstract A series of glycol dibenzoates was synthesized by transesterification of glycols with methyl benzoate. PVC films were prepared from suspension grade PVC and the dibenzoates at a constant content of the dibenzoates. The mechanical properties of the films were measured. In addition, the extractability and the a…
