Cavitation theory is used to predict the acoustic pressure at the boundary of the inertial/non inertial threshold for a range of bubble sizes. The sound field generated from a commonly employed sonoelectrochemical cell is modelled. The model is tested with a calibrated hydrophone far from the transducer to avoid spati…
Transparent monoliths made of new interpenetrating networks based on titanium-oxo-poly(hydroxyethyl methacrylate) (PHEMA) nanocomposites are obtained through one pot synthesis with low shrinking and show a strong laser-induced darkening activity.
Subcontinuum phonon conduction phenomena impede the cooling of field-effect transistors with gate lengths less than 100 nm, which degrades their performance and reliability. Thermal modeling of these nanodevices requires attention to a broad range of length scales and physical phenomena, ranging from continuum heat di…
Vanadium alloys are attractive candidate structural materials for breeding blanket of fusion reactors because of their low activation properties and high temperature strength. Studies on various blanket designs are being carried out using vanadium alloys as structural materials and liquid lithium or molten salt Flibe…
A cost-effective and environmentally friendly method to dissolve microcrystalline cellulose (MCC) has been utilized. A detailed investigation of the effects of cellulose amount and solvent (aqueous NaOH) concentration on MCC solubility has been presented. In the experiments, NaOH solutions with concentrations ranging…
The advantage of helium plasma treatment in enhancing endothelial cell growth and adhesion on polyurethane film coated on glass substrate is demonstrated with experimental data. Human coronary artery endothelial cell (HCAE) growth and attachment was studied on (1) bare glass substrate, used as control, (2) coated glas…
Electrical conduction properties of Sr-doped and Sr-doped under and conditions were investigated with conductivity measurements. Conductivities of Sr-doped were at under wet reducing conditions and were close to those under wet oxidizing conditions. It was found from the H/D isotope effect on conductivity that the mat…
New series of non-symmetric bent-core compounds with a terminal carboxylic function as well as its benzyl esters and pentafluorophenyl esters have been synthesised. For most pentafluorophenylesters and for a benzylester with fluorine atoms in the ortho positions to the alkoxy chain different types of columnar ribbon p…
An esterase that specifically hydrolyzes medium-chain (C(3)-C(5)) monoalkyl phthalates was purified from phthalate-grown Micrococcus sp. YGJ1. The enzyme activity was split into two fractions by hydrophobic chromatography on Phenyl Sepharose, and the enzymes were purified to homogeneity from each fraction. The purifie…
The ferrite (α)+cementite (θ) microduplex structure formed by heavy cold rolling and annealing of pearlite was studied in an Fe-1.4Cr-1.0C (mass%) alloy. Cold-rolled pearlite structure is inhomogeneous consisting of three components; (1) irregularly bent lamellae (IBL), (2) coarse lamellae with shear band (CLS) and (3…
Under the structure-directing effect of a metal complex formed in situ, supertetrahedral [ZnGe3S6(H2O)(S3)(1/2)]1- clusters alternate with tetrahedral Zn(H2O)(S3)(1/2)1- units to form a two-dimensional wide bandgap semiconductor that shows photocatalytic activity for H2 production from aqueous solution.
Photophysical studies of a newly synthesized fused subphthalocyanine dimer-C60 revealed a complex cascade of energy transfer events to succeed the initial SubPc dimer photoexcitation.
The three-dimensional structure of nanocrystalline GaN has been studied by X-ray diffraction, Rietveld and atomic pair distribution function (PDF) analyses. The material is of very limited structural coherence, yet possess a well-defined atomic arrangement resembling the wurtzite structure. The study demonstrates the…
A "sandwich" type polyoxometalate catalyst ([MeN(n-C8H17)3]12[WZn3(ZnW9O34)2]) was very efficiently recycled by nanofiltration with almost quantitative retention, using an alpha-alumina supported mesoporous gamma-alumina membrane.
Breakaway oxidation of 15–18 % Cr ferritic stainless steels occurring in water vapour is described in the temperature range 800–1000°C. The failure of the protective chromia scale leads to iron oxide(s) nodule formation with accelerated kinetics. Characterisation of the (Fe,Cr)2O3 initial oxide scale by Raman spectros…
An in situ surface study of the carbon dioxide corrosion of mild steel has been undertaken using the tandem technique of mixed potential/synchrotron radiation-grazing incidence X-ray diffraction (SR-GIXRD). Long-term monitoring of the mixed potential showed there was an initial shift toward cathodic potentials attribu…
The synthesis and structure of a novel decanuclear copper(II) cage is reported. The assembly of the cage is facilitated by the cumulative coordinative interaction of tert-butyl phosphonate, 2-pyridylpyrazole and hydroxide ligands with copper(II) ions. Magnetic studies of this decanuclear copper(II) cage indicate compl…
Well-defined macroporous ceramics consisting of TiO2 and ZrO2 have been fabricated by two methods. One is via a template-assisted colloidal processing technique and the other is via a hetero-coagulation of template/ceramic particle colloidal processing. The former technique is as follows. Close-packed polymer spheres…
In a previous study, we found that different collagen gels produced using collagen fibrils extracted from 1-, 4- and 8-month-old rat tails essentially influenced the morphogenesis of epithelial cells. More importantly, the youngest collagen gel induces the highest level of cell apoptosis. The objective of this study w…
Alloying process and shape memory properties of a Ti/Ni multilayer thin film fabricated by a dual d.c. magnetron sputter–deposition method were investigated, and compared with those of a Ti—Ni amorphous thin film fabricated by an alloy target sputter–deposition method. The multilayer thin film was made by depositing T…
