Silk gland factor-1 (SGF-1) regulates transcription of the Bombyx sericin-1 gene via interaction with the SA site. In this study, two related SGF-1 polypeptides of apparent molecular masses of 40 and 41 kDa were purified. Specific interaction of these proteins with the SA site was demonstrated by electrophoretic mobil…
Abstract Inert gas condensation was used to generate nanocrystalline La‐doped CeO 2 − x . Non‐stoichiometric CeO 2 − x ‐based materials were found to be excellent catalysts in recent studies for the selective reduction of SO 2 . To understand better the stoichiometry‐related catalytic properties, the surface chemistry…

Carbon steel specimens were exposed in carbon dioxide (CO2)-containing brine with different amounts of hydrogen sulfide (H2S) at 70°C and 80°C. The addition of 0.02 mmol/L sulfide, corresponding to 45 Pa (0.0065 psi) H2S partial pressure (PH2S), to brine with 70 kPa (10 psi) CO2 at pH 4.2 caused rapid formation of a p…

Abstract This work investigates unit cell dimensions, crystal size and specific surface area of aluminous goethite that was progressively dehydroxylated to form hematite. Goethite synthesized from the ferrous system altered to hematite with DTGA maximum increasing from 236° to 273°C for 0 to 30.1 mole % Al-substitutio…
Salt layers play an important role in many electrochemical dissolution processes. The composition of salt films formed on austenitic stainless steel have, for the first time, been determined using in situ energy dispersive x‐ray fluorescence microanalysis during dissolution in a chloride solution. The electrode was th…

Magnetoliposomes for hyperthermia treatment of cancer were prepared by coating phospholipid on to magnetite particles. The optimum phospholipid composition for dispersibility was a phosphatidylcholine/phosphatidylethanolamine ratio of 2:1. The average size of the magnetoliposomes, which were aggregates of 10 nm core m…

In certain cases, lyotropic lamellar phases under shear form structures corresponding to a close-packed assembly of multilayered vehicles. We present light and neutron scattering data showing that these micrometer-sized objects may exhibit a long-range order under shear similar to that which has been observed for rigi…

The attachment of bacteria to solid surfaces is influenced by substratum chemistry, but to determine the mechanistic basis of this relationship, homogeneous, well-defined substrata are required. Self-assembled monolayers (SAMs) were constructed from alkanethiols to produce a range of substrata with different exposed f…

The design and fabrication of large-area, high-efficiency metallic gratings for use in high-power laser systems is described. The gratings exhibit a diffraction efficiency in excess of 95% in the m = -1 order (Littrow mount) and have a high threshold for laser damage. Computations and experimental measurements are pre…

Li is intercalated into (XRG) films up to a stoichiometry of . The spin‐coated films are highly reversible hosts for Li and do not support cointercalation of solvent molecules. The specific energy , and specific capacity are higher than any reported previously for xerogel materials or for other vanadium oxides. It is…

We investigate by Monte Carlo simulations the diffusion of ions in ordered and structurally disordered lattices, where the Coulomb interaction between the mobile ions is explicitly taken into account. Results for tracer diffusion, conductivity, the diffusion-induced spin-lattice relaxation rate, and the incoherent int…
