Tunable Non-locality of Thermal Non-linearity in Dye Doped Nematic Liquid Crystal
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…

Century 21 - Pregnant with Ozone
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…
Phase diagrams of dilute binary alloys
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…
Characteristics of porous nickel-titanium alloys for medical applications.
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…
Alumina ceramics for ballistic protection. Part 1
High-alumina and alumina-zirconia ceramics have been successfully used as armor material for personnel and vehicular ballistic protection.
Polyelectrolyte multilayer films modulate cytoskeletal organization in chondrosarcoma cells
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…
Performance of Solid Oxide Fuel Cells with LSGM-LSM Composite Cathodes
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…
Ni Catalyst for Hydrogen Conversion in Gadolinia-Doped Ceria Anodes for Solid Oxide Fuel Cells
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…
Study of the formation of mesoporous titania via a template approach and of subsequent Li insertion
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…
Synthesis, Spectra and Photophysics of some Free Base Tetrafluoroalkyl and Tetrafluoroaryl Porphyrins with Potential Applications in Imaging¶
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…
Porphyrins in 1,3-Dipolar Cycloaddition Reactions: Synthesis of a Novel Pyrazoline-fused Chlorin and a Pyrazole-fused Porphyrin
β-Nitro-meso-tetraphenylporphyrin reacts with diazomethane to give a pyrazoline-fused chlorin as the main product. This compound was converted into the corresponding pyrazole-fused porphyrin, by treatment with DBU, and into a methanochlorin by refluxing in toluene.

Carbon dioxide extraction of residual chloroform from biodegradable polymers
Biodegradable polymeric devices for drug delivery and tissue engineering are often fabricated with the use of organic solvents and may still contain significant amounts of solvent (> 1 wt%) even after aggressive vacuum drying. This excess solvent can interfere with tissue response and the mechanical properties of the…
Signature of the Meyer–Neldel rule on the correlated barrier-hopping model
In this study, a modified model for bipolaron correlated barrier hopping (CBH) is proposed, since the usual bipolaron CBH model has been found to be inconsistent with experimental data for ac conductivity for chalcogenide glasses at high temperatures. The present model is based on the existence of a focal point when t…
Influence of Zirconium Alloy Chemical Composition on Microstructure Formation and Irradiation Induced Growth
The studies of the dislocation structure, phase, and microchemical compositions of alloy Zr-1Nb-1.2Sn-0.35Fe (E635) and its modifications containing Fe from 0.15 to 0.65% were carried out before and after research reactor irradiation at ∼350°C to maximal fluence of ∼1027 m-2 (E > 0.1 MeV) and at ∼60°C. The size…
Thermal conductivity measurements of epoxy systems at low temperature
We have developed a specific thermal conductivity measurement facility for solid materials at low temperature (LHe and LN2). At present, the Measurement of Thermal Conductivity of Insulators (MECTI) facility performs measurements on epoxy resin, as well as on bulk materials such as aluminum alloy and on insulators dev…
