Abstract New nickel(II) and palladium(II) complexes having both hydrido and arylthiolato ligands, MH(SAr)(PCy3)2, and complexes with aryl and mercapto ligands, Ni(Ar)(SH)(PEt3)2 (M = Ni, Pd; Ar = C6H5-,p-CH3-C6H4-, p-CH3OC6H4-), were prepared. Thermolysis of these complexes caused cleavage of the S–C or S–H bond to ev…

Abstract The effects of selected cationic and anionic impurities on the precipitation of gypsum in aqueous brine have been studied in a continuous MSMPR crystalliser. Crystal size distributions, determined by in situ Malvern laser light‐scattering measurements, were found to be bimodal. The suspected presence of agglo…

Abstract Graft copolymers of acrylonitrile and of acrylic acid monomers on cellulosic materials were obtained by use of ceric ion initiator in aqueous medium at a 50% (w/w) cellulose‐monomer ratio. The variations of poly(acrylonitrile) grafts and of the efficiency of grafting with ceric ion concentration, and of poly(…

The plastic deformation around spherical indentations on a {100} face of single crystals of MgO has been studied with cathodoluminescence in a scanning electron microscope and by optical interferometry. Bd on the experimental observations, a model is presented which relates the movement of the displaced material, the…

The surfaces of cells of several species of cyanobacteria have been studied using low-temperature scanning electron microscopy (SEM), and have been shown to be covered in a layer of hydrated mucilage. This mucilage is observed in specimens of Anabaena azollae adhering to plant cells in their natural symbiotic niche (t…

Abstract Polyethyloxazoline (PEO x ) blends with several other thermoplastic polymers were examined by differential scanning calorimetry (DSC) for miscibility. Styrene/acrylonitrile (SAN) copolymers having compositions in the range of about 20–40% acrylonitrile (AN) by weight were found to be miscible with PEO x where…

Incubation of the neutral metalloendopeptidase thermolysin at pH 7.2 in the presence of EDTA and/or low concentrations of calcium ions produces fast enzyme inactivation as a result of autolysis. The 'nicked' protein is a folded species composed of three tightly associated protein fragments. Dissociation of this comple…

Abstract Alternating mica-like and smectite-like layers of rectorite give rise to periodically varying contrast in 10-Å lattice fringes, yielding a periodicity of 20 Å in a transmission electron microscopic study. Expansion of rectorite using dodecylamine hydrochloride yields a three-layer repeat of thickness 32–35 Å,…

The cores of the individual superpartials which comprise a [10l] screw superdislocation dissociated on the (111) and (010) planes in L12 ordered materials have been investigated using computer simulation techniques for the case where antiphase boundaries (APBs) on (111) planes are unstable. The superdislocation dissoc…

Microlite, rangrng from crystalline to metamict, is a principal accessory in several lithologic units of the Harding pegmatite, Taos County, New Mexico. From the sequence of lithologic units within the pegmatite, crystallization of microlite from the pegmatite magma is inferred to have begun relatively late, after the…
