Accelerated durability tests are commonly used with the intent of predicting service performance. To make these predictions it is necessary to extrapolate the accelerated data to service conditions. A review is given of a number of techniques and models used to extrapolate data from ageing and environmental resistance…

The thermolytic decomposition of citric acid in the presence of tin/lead solder has been investigated. The solid reaction products were first examined by solid-state 13 C NMR. The samples were then dissolved in D 2 O, and 1 H and 13 C 1D and 2D (HMQC, TOCSY) spectra were obtained. Results indicate the presence of a se…

An effective acceleration technique using digital feedback to control the flux waveform of a single sheet tester has been developed. In this technique, the waveform of the applied voltage is pre-estimated using the equivalent circuit equation. The convergence characteristic of the proposed method using the new techniq…

On the corrosion protection of carbon steel by sol-gel derived TiO2 coating under the illumination of light, the photoelectrochemical behavior of TiO2/steel system is investigated. The diffusion of Fe ions into TiO2 in the heat treatment of the coating process greatly degrades the photo-effect of TiO2 coating. An Fe o…

Highly reactive and ultra-fine barium polytitanates (BaO-nTiO2, n= 4, 4.5, 5) with a particle size of 30–50 nm have been prepared by the citrate route. Solubility isotherms were calculated for the BaCO3-citric acid-H2O and TiO(OH)2-citric acid-H2O2-H2O systems at 25 °C to predict the optimum pH condition for preparing…

Novel 2,3,6,7,9,10-hexasubstituted phenanthrene derivatives have been synthesized, which showed broad enantiotropic columnar phases. A mixture of one representative bearing six (S)-2-methyl-3-oxa-decanoyloxy side chains with its 1,2,3,6,7,8-hexasubstituted structural isomer showed a tilted columnar phase and exhibited…

The optical and electrical conductivity behaviour of phases in the systems CsMIIX3(MII= Ge, Sn, Pb; X = Cl, Br, I) are explained by donation of electron density from non-bonding electron pairs on the MII metal into a conduction band formed by the overlap of halogen d states. The greater ionic character of the PbII red…

Some new photoresponsive azobenzenes (1–5) have been synthesized and characterized. On irradiation at 330 nm these systems undergo conversion from the E to the Z form to a varying extent which depends upon the nature and position of substitution on the azobenzene rings. They revert back to the E form on thermal isomer…

Ca4Y6(SiO4)6O:A (A = Pb2+, Eu3+, Tb3+, Dy3+) phosphors have been prepared by two methods: the sol-gel method and the conventional dry method. The crystallization processes and the luminescence characteristics of the phosphors were studied. The sol-gel method features low-temperature formation of the phosphor, leading…

Abstract Ultisols and Oxisols in Malaysia are characterized by low pH and high Al, with their subsoils usually deficient in Ca, Mg, or both. An experiment, using polyvinyl chloride columns, was conducted to study chemical reactions in a representative Ultisol and Oxisol from Malaysia resulting from application of grou…

The acidic sites in Cu/ZSM-5 catalysts active for the reduction of nitrogen oxides under lean conditions have been investigated by examination of the IR spectrum of adsorbed pyridine: proton and sodium forms of the zeolite have also been studied to provide reference results. As expected, H-ZSM-5 exhibited both Lewis a…

Novel, neutral EuIII, GdIII and YbIII complexes have been obtained with tetraaza-macrocyclic ligands containing three phosphinate and one carboxamide co-ordinating arms. The overall results are consistent with a co-ordination geometry based on the octadenticity of these ligands. Among the possible 16 enantiomeric pair…

Differential scanning calorimetry (DSC) curves of levofloxacin hemihydrate measured under various conditions showed different thermograms. These phenomena were attributed to be the dehydration. Dehydration caused a multiple-phase transition. Dehydration at a higher temperature (above 70°C) gave a sharp endothermic pea…

The synthesis process and the formation mechanism of Al4SiC4 were investigated using Al, Si, and C as starting materials. Properties such as hydration resistance of the synthesized Al4SiC4 were examined. SiC and Al4C3 begin to form from about 800°C and 900°C, respectively. When the temperature is above 1300°C, both pr…
