The synthesis and characterization of the mesomorphic and dielectric properties of new imine-based liquid crystalline compounds that exhibit tilted SmC* phases is reported. The presence of an imino linkage within the mesogenic nucleus of these compounds is significant due to the ability of benzaldimines to coordinate…
The [Co(hfac)2·CH3OCH2CH2OCH3] adduct was synthesised and investigated by X-ray crystal structure, mass spectra, TG-DTG thermal measurements and infrared transmittance spectroscopy. X-Ray single crystal data provide evidence of a slightly distorted octahedral cobalt cation, coordinated with four oxygen atoms of two hf…
Fully biodegradable, environment-friendly ‘green' composites were fabricated using glutaraldehyde (GA) modified (MSPC-1) and GA and poly(vinyl alcohol) modified (MSPC-2) soy protein concentrate (SPC) resins. The SPC modifications resulted in better thermal and mechanical properties and lower moisture absorption due to…
Ethyl-substituted ammonium cation allows the preparation of an unprecedented oxo- and oxalato-bridged supramolecular three-dimensional network. The compound exhibits magnetic ordering with Tc = 70 K due to a weak spin canting.
In recent years, the field of porphyrin chemistry has expanded to include several new analogs of the original four pyrrole, carbon-bridged systems. This review traces the development of one such class of new macrocycles, namely Schiff-base porphyrin analogs. The review's focus is on the synthesis and properties of the…
5'-Fluoro-5'-deoxy-D-ribose-1-phosphate (FDRP) is identified as a biosynthetic intermediate during fluorometabolite biosynthesis in Streptomyces cattleya.
The dissociation of NO on Rh(100) surfaces has been modelled by kinetic Monte-Carlo (MC) simulations including nearest neighbour (NN) and next-nearest neighbour (NNN) interactions, and zero-coverage kinetic parameters obtained from experiments. Two approaches were performed to derive the lateral interactions. First, t…
Catalytic combustion of butane in micro-scale conduits is investigated. Nano-porous alumina formed through anodic oxidation of aluminum is employed for the support of platinum catalyst. Combustion starts at 250°C, and a heat release rate up to 710MW/m3 is achieved in a 0.6mm ID tube. It is found that the surface react…
The diffusion coefficient of Cu in (Ti, Zr)N was measured by X-ray diffraction (XRD) and four-point probe (FPP) analyses after annealing Cu/(Ti, Zr)N/Si multilayered samples in the temperature range of Cu diffusion in (Ti, Zr)N had components from both the grain boundaries and the lattice based on diffusional analysis…
The application of ATP-loaded liposomes has been shown effective against ischemic damage in several tissues. In this study, we have prepared ATP-containing liposomes capable of specific recognition of component (myosin) specific for ischemic myocardium. ATP-containing immunoliposomes specific towards cardiac myosin we…
A series of optimised materials in the family with parent compound La(2)Mo(2)O(9) have been studied using the isotope exchange depth profile technique and SIMS analysis. The data collected indicate that the oxide ion diffusion coefficients in both the parent compound and optimised materials are significantly higher th…
Optical vibrations of the lattice and the electron–phonon interaction in polar ternary mixed crystals are studied in the framework of the continuum model of Born and Huang and the random-element-isodisplacement model. A normal-coordinate system to describe the optical vibration in ternary mixed crystals is correctly a…
Structural materials in fusion reactors will operate in harsh radiation conditions including high displacement rates from 14 MeV neutrons with accompanying high levels of hydrogen and helium production and will experience severe property degradation. Predicting their in-service performance requires a detailed understa…
Using a binder-less PcBN tool, improvement of processing efficiency was tried in machining of a vanadium-free titanium alloy, Ti-6Al-2Nb-1Ta which was recently applied for a surgical implant material. The tool which is prepared through the direct conversion sintering of h-BN under both high pressure and temperature, e…
The mechanical properties of free standing films of as prepared and acid purified single-walled carbon nanotubes were studied by means of tensile stress measurements as well as electron microscopy. Films appear to fail by crack propagation involving rupture or matrix pull-out of bridging nanotube bundles.
Lu2Pc2 and lithium hexylthio-phthalocyanine have been used to synthesize [Lu2(Pc)4] which exhibits variable range hopping conductivity as inorganic semiconductors and also observed electrochromic effect from cyclic voltammetric (CV) measurement.
We first provide an overview of some predominant theoretical methods currently used for predicting thermal conductivity of thin dielectric films: the equation of radiative transfer, the temperature‐dependent thermal conductivity theories based on the Callaway model, and the molecular dynamics simulation. This overview…
Plastic formability in the secondary processing of an AZ31 magnesium alloy was investigated using fine-grained and relatively coarse-grained materials, respectively. To produce components for mobile electric appliances, boss formability was examined at a relatively low temperature of 523 K. The boss with a height of 1…
The adsorption properties of water adsorbed on various silica substrates are investigated by way of Grand Canonical Monte Carlo simulations (GCMC). The SPC and PN-TrAZ potential are used to describe water–water and water–silica interactions. The numerical sample of mesoporous silica glass (pore size: 3.6 nm) was obtai…
A new bis(indenyl)zirconocene bearing a pendant Si-Cl anchor has been grafted onto MCM-41, SBA-15, MCM-48 and a disordered mesoporous silica for the polymerisation of ethylene and propylene, producing polymers with very high molecular weights, low polydispersities and, in the case of polypropylene, higher levels of is…
