The pentanuclear cluster [Au3Cu2(C2Ph)6]– was obtained from the reaction between [{Au(C2Ph)}n] and a mixture of [Au(C2Ph)2]– and [{Cu(C2Ph)}n]. Its structure is described. The same cluster has been synthesized in a stepwise manner starting with [Au(C2Ph)2]– through the binuclear complex [Au2(C2Ph)3]– and the trinuclea…

The transmittance spectra of twisted states of surface stabilized ferroelectric liquid crystal cells were measured under a polarizing optical microscope. It was found that the two twisted states give different spectra, as expected by an apparent color difference. There were two cases; in one case the two spectra inter…

Abstract Graft polymerization of acrylamide onto rice starch was investigated under different conditions using potassium persulphate, benzoyl peroxide or potassium permanganate as initiator. This has led to establishment of the most appropriate grafting conditions for each of these initiators. Under these conditions g…

Over the past few years, a number of techniques have evolved for detecting discharges in the insulation systems of electrical machines by measuring the discharge currents flowing at the machine terminals. The propagation of these currents through the winding, from the discharge site to the terminals, is influenced by…

The synthesis and characterisation of gold(II) complexes with o-aminobenzenethiol is reported. The e.s.r. results indicate that the highest occupied molecular orbital has appreciable contribution from the sulphur donors of the ligands. It is the first time that binuclear gold(II) complexes giving well resolved seven-l…

A new genus Actinokineospora is described. It is characterized by forming chains of zoospores originating from aerial mycelium, and has type IV/A cell walls and a type PII phospholipids pattern. The major menaquinone is MK-10. No mycolic acids are present. The guanine-plus-cytosine content of the deoxyribonucleic acid…

The initial adsorption, structural transition, and polymeric growth of 1‐octyne‐3‐ol on iron electrode from sulfuric acid solutions have been examined by using time‐resolved in situ automatic ellipsometry. The adsorption occurs in two different configurations, flat and partly upright. The structural transition of the…

Mechanical properties of SiO2-Al2O3 ceramics were studied in relation to the chemical composition. Raw powders of the composition ranging from 60 to 78wt% Al2O3 were synthesized by the spray pyrolysis method and sintered at 1650°C for 4h. The room temperature flexural strength and fracture toughness of the specimens s…

Measurements of the reversible component of magnetization or reversible (backward) differential permeability made on 1% Mn pipeline steel at numerous points around major and minor hysteresis loops and on initial and anhysteretic curves are described. It is found that the reversible component of magnetization is a sing…

Abstract In the search for the causes of diatom assemblage distribution, a combination of two multivariate analyses has been used. Principal component analysis and canonical correlation analysis have allowed us to find suitable relationships between biological and physicochemical parameters. As a result, water salinit…

Abstract A technique for characterization of polymer blends by low voltage scanning electron microscopy is described. The method allows observation of the distribution of phases in a blend due to good topographical and compositional contrast. This is possible because of lower beam penetration and high secondary emissi…

The morphology of potassium hydrogen tartrate (KHT) crystals precipitated from ethanol-water solutions and from white wines from the Penedes (Spain) is reported. In each case, the rate of precipitation is influenced by agitation, supersaturation, and temperature. Precipitation of KHT from wines differs from that from…

Co-condensation of silver atoms with monomeric SiO and an excess of argon yields Ag(SiO) and probably Ag2(SiO), identifiable by their i.r. spectra; 28,29,30Si and 16,18O isotopic shifts imply not a linear but a triangular structure for Ag(SiO) with ∠ AgSiO ⩽ 90°

The birefringence of mixtures of homologues from the terminally non-polar series of p,p′-dialkylazoxybenzenes has been studied. The birefringence is used as a probe of the orientational order parameter, which is coupled to the translational (smectic) order parameter. The tricritical nematic to smectic-A point which re…

Classical levitation melting process using conventional conical inductcr can not be used at industrial scale because of the limited size of liquid metal which can be maintained in equilibrium against gravity force. Because of high frequency and axisymmetry of magnetic field distribution, a stagnation point occurs at t…
