A unique nonwoven 3D fabric-forming process, designed to bind a set of linear yarns that is arrayed in either uniaxial or multiaxial orientation, was identified, characterised and termed noobing five years ago. The produced 3D fabric, usually intended for composite materials application, is layerless and comprises cri…
The perovskite-type compounds Ba2LnReO6 (Ln = Y, Nd, Sm–Lu) have been synthesized. Powder X-ray diffraction measurements and Rietveld analysis show that they are monoclinic with space group P21/n and that Ln3+ and Re5+ ions are structurally ordered. Anomalies are found in their magnetic susceptibility and specific hea…
Numerical methods to predict the solubility of anthracene in mixed solvents have been proposed. A minimum number of 3 solubility data points in sub-binary solvents has been employed to calculate the solvent-solute interaction terms of a well established colsolvency model, i.e. the combined nearly ideal binary solvent/…
Recently, a new class of copolymers, so-called protein-like copolymers has been predicted theoretically by computer simulation. In these copolymers, the conformation of the copolymer determines the exposure of certain comonomer units to the outer solution. Depending on the conformation, copolymer molecules with essent…
We have shown for the first time experimentally that the O2 and O4 sites of uracil have different proton affinities, and as implied in previous computational studies, the O4 is more basic and would be energetically preferred in an orotate ribose 5'-monophosphate decarboxylase catalysis mechanism involving proton trans…
The synthesis of mesoporous silicas in the presence of the dicationic gemini surfactant [CH3(CH2)15N(CH3)2(CH2)3N(CH3)3]Br2 (C16-3-1) has been investigated at low temperatures (−4 °C) under basic and acidic conditions. Under basic conditions, the SBA-2 phase (based on a close-packed arrangement of micelles and exhibit…
The quality of work rolls that come into direct contact with the steel product has a direct effect on product quality and mill operation. A forged steel with a chromium content of 5 mass% has been conventionally used to meet the requirement of metallurgical structure homogeneity and high hardness for work rolls in col…
The binding of TSPP by a dithienylethene-tethered beta-cyclodextrin dimer can be altered reversibly by irradiation with light.
In this paper we report on experiments performed to estimate the non-locality of the photothermal non-linearity in thick dye-doped nematic liquid crystal (DDNLC). We have studied the interaction of two counter-propagating self-focused laser beams parallel to each other. From this experiment, a rough estimation of the…

As we enter this new century, it is striking how the number of applications for ozone is growing. During ozone's first century, the emphasis for using it involved primarily, potable water treatment, wastewater treatment, bottled water treatment, odor control and medical therapy. Of these, potable water and wastewater…
In this volume, regarded as a supplement to the Desk Handbook: Phase Diagrams for Binary Alloys published in 2000, the editor has included all the information available on limited solubility in every binary system. While the smaller format of the desk handbook served well in providing overall information, the range of…
We investigate the behavior of NiTi porous alloys, possessing the property of shape memory, by using different characterization methods XPS, Auger, DSC and SEM. The study mainly focuses on the determination of porosity, surface characteristics and the phase transformation. In the case of porous material the biomechani…
High-alumina and alumina-zirconia ceramics have been successfully used as armor material for personnel and vehicular ballistic protection.
The aim of this study was to evaluate polyelectrolyte multilayer films as interfaces for implants. Polyelectrolyte multilayers were built up with different terminating layers by alternate deposition of oppositely charged polyelectrolytes on which chondrosarcoma (HCS-2/8) cells were grown in the presence of serum. Film…
Anode-supported cells comprising zirconia (YSZ) anode, thin YSZ electrolyte, and composite cathodes containing a mixture of (LSM) and (LSGM) were fabricated. The relative proportions of LSGM and LSM were varied between 30 wt % % LSM and 70 wt % % LSM, while the firing temperature was varied between 1000 and 1200°C. Th…
A gadolinia-doped ceria (CG4) is considered as anode material for solid oxide fuel cells with an yttria-stabilized zirconia electrolyte. Symmetrical cells are mounted in a novel setup geometry with auxiliary electrodes to avoid concentration polarization outside the electrode structure. The polarization resistance in…
Mesostructured titania was prepared according to Rao et al. using dodecylamine as the amine template. X-Ray absorption spectroscopy was used to study changes in the Ti local coordination environment during formation of the mesoporous material—starting from the alkoxide precursor, followed by hydrolysis and condensatio…
The synthesis, characterization and photophysical properties of two perfluoroalkyl (5,10,15,20-tetrakis-[trifluoromethyl]- and [heptafluoropropyl]-porphyrin) and two perfluoroaryl (5,10,15,20-tetrakis-[2,6-difluorophenyl]- and [pentafluorophenyl]-porphyrin) are described, with reference to their potential in both phot…
