Abstract The crystal structures of yellow Cu 3 PS 4 and of black Cu 3 SbS 4 were refined from single crystal X-ray diffraction data. Cu 3 PS 4 crystallizes orthorhombic in an ordered wurtzite superstructure type with the space group Pmn 2 1 (no. 31), a = 7.282(1) Å, b = 6.339(1) Å, c = 6.075(1) Å, V = 280.38(8) Å 3 ,…

We describe the variational limit of one-dimensional nearest-neighbour systems of interactions, under no structure hypotheses on the discrete energy densities. We show that the continuum limit is characterized by a bulk and a interfacial energy density, which can be explicitly computed from the discrete energies throu…

A hybrid inorganic-polymer composite was formed through nanosize silica filler particles (< 30 nm) that were incorporated inside a nylon-6 matrix. The composite was microtomed and examined with TEM which revealed that the silica particles were well dispersed and non-aggregated. Optimization of the synthesis conditions…

Semiconducting properties of two types of cubic boron nitride (cBN) single crystals prepared at high pressure and high temperature were evaluated by Hall measurement. Sulfur was intentionally doped in one type as a donor and the other type contained no intentional dopants. Both crystals exhibit n-type conduction. Sulf…

The size effect on thermal conductivity of a free-standing wire with rectangular cross-section is investigated. The electronic thermal conductivity is calculated within a Boltzmann transport equation approach. A simple expression for the reduction in conductivity due to the increase of boundary scattering is presented…

This research is a comparative study of the structural and physical properties of ring, rotor, and friction spun yams and an attempt to explain the differences in their physical properties on the basis of yam structure. Results show that the ring spun yam exhibits the highest fiber migration, followed by rotor spun ya…

Forty-nanometer-thin free-standing membranes with 55-nm-wide pores have been prepared via Langmuir−Blodgett transfer. Hydrophobized silica colloids and polyisoprenes with quaternary ammonium headgroups were jointly spread onto a water surface to form a hybrid monolayer in which two-dimensional ordered domains of parti…

Abstract Micromorphological studies were performed in order to understand the factors and processes involved in the formation of calcium carbonate (CaCO 3 ) in twenty three soil series of Vertisols representing sub-humid, semi-arid and arid climatic regions of Peninsular India. The study indicates that Vertisols conta…

Ni , Zn , Pd and Pt tetra(pentafluorophenyl)porpholactone (TFPL) were synthesized and identified by their optical and mass spectra. The lactone ring was produced from the parent free-base porphyrin using silver nitrate and oxalic acid with a yield of 73%, and the metals were inserted by standard procedures from metal…

Excitonic effects are observed in the optical absorption and photoluminescence of strongly confined CdS quantum dots embedded in the polymer Nafion. The three bands identified in the optical absorption spectra could be attributed to 1se-1sh, 1pe-1ph, and 2se-2sh transitions of the noninteracting particle model. Photol…

The room temperature plastic deformation behaviour of two different batches (with differences in chemical composition) of 316L austenitic stainless steel has been studied. By thermomechanical treatments, a wide range of grain sizes varying from 2·7 to 64·0 νm was obtained in this study. The different microstructural p…

Measurements of the electrical resistivity of thin copper films sputtered onto silicon dioxide, in real time, are reported. The electrical resistivity is shown to strongly depend on the film’s thickness for thicknesses below the bulk mean free path of copper (39 nm). Model fits to the electrical resistivity combined w…

The phase and orientation of manganese nitride grown on MgO(001) using molecular beam epitaxy are shown to be controllable by the manganese/nitrogen flux ratio as well as the substrate temperature. The most N-rich phase, θ phase (MnN), is obtained at very low Mn/N flux ratio. At increased Mn/N flux ratio, the next mos…

The excretion of extracellular polymeric substances (EPS) by an axenic culture of the benthic diatom Cylindrotheca closterium was investigated. Two sequential extraction steps proved to be sufficient to remove the bulk of the EPS present. Soluble EPS was recovered by a simple centrifugation step and represented a frac…
