The cryptate [EuII(2.2.2)(H2O)2]2+ displays several interesting features with respect to pO2 responsive MRI contrast agent applications: it is relatively stable against oxidation, it has two inner sphere water molecules, and the water exchange and electron spin relaxation rates are in the optimal range to attain high…
Iron(III) tetraphenylporphyrin triflate, Fe(tpp)OTf, works as an efficient and characteristic Lewis acid catalyst in the selective rearrangement of α,β-epoxy ketones into 1,2-diketones.
Mesocellular carbon foam composed of nanometer sized primary particles was synthesized using hydrothermally synthesized MSU-F silica as a template and poly(furfuryl alcohol) as a carbon source.
In order to elucidate design principles for biocompatible materials that can be created by in situ transformation from self-assembling oligopeptides, we investigate a class of oligopeptides that can self-assemble in salt solutions to form three-dimensional matrices. This class of peptides possesses a repeated sequence…
Transparent silica glasses were obtained by sintering a green compact (fabricated by slip-casting methods for high-purity silica glass powder) in diverse atmospheres. The relationships between sintering atmosphere and sintering temperature that result in transparent, sintered silica glass were shown. The results indic…
Argon- and air-plasma treatments have been used to modify the surface of sisal fibres. The Taguchi method of experimental design with three factors and three levels is used to optimise the treatment parameters in relation to fibre strength. The effects of plasma treatment on interfacial bonding between sisal fibres an…
Lignocellulosic natural fibers like sisal and pineapple leaf fiber (PALF) can be incorporated in polymers based on biodegradable polyester amide matrix, BAK 1095 for achieving desired properties and texture in the resulting biocomposites. But high level of moisture absorption, poor wettability and insufficient adhesio…
In the present study, diffusion bonding was used to join Ti -6Al- 4V alloy to a microduplex stainless steel using a pure copper interlayer. The effects of heating rate and holding time on microstructural developments across the joint region were investigated. After bonding, microstructural analysis including metallogr…
Interactions among local pit sites were investigated using a 5 × 5 array of 25 electrodes consisting of closely spaced, flush-mounted 316 stainless steel wires. Three types of interactions occurred when actively corroding pits existed while the remaining electrodes were initially passive in 0.05 M NaCl solution. Suppr…
Mechanical alloying followed by pulse discharge sintering (MA-PDS) has been employed to develop the bulk (Bi1−xSbx)2Te3 thermoelectric materials with various Sb alloying contents. Substitutional solid solutions of (Bi1−xSbx)2Te3 are formed in the whole Sb content range by MA-PDS process. The sintered compacts are dens…
Studies on redox supercapacitors employing electronically conducting polymers are of great importance for hybrid power sources and pulse power applications. In the present study, polyaniline (PANI) has been potentiodynamically deposited on stainless steel substrate and characterized in a gel polymer electrolyte (GPE).…
A novel ferromagnetic complex [BrFBzPy][Ni(mnt)2], where [BrFBzPy]+ = 1-(4′-bromo-2′-fluorobenzyl)pyridinium and mnt2− = maleonitriledithiolate, has been prepared and characterized. In the crystal structure the most prominent feature is that the [Ni(mnt)2]− anions and [BrFBzPy]+ cations form a well-separated stacking…
New grain evolution taking place during superplasticity was studied by means of tensile tests as well as metallographic observation for a unrecrystallized coarse-grained 7075 aluminum alloy. Grain boundary sliding (GBS) frequently takes place even on the layered high angle boundaries (HABs) parallel to the tensile axi…

The biomaterials research field has broadened in the last 3 decades, including replacement of diseased or damaged parts, assist in healing, correct and improve functional abnormality, drug delivery systems, immunological kits and biosensors. Proteins play crucial role in almost every biological system. They are involv…
Celecoxib exhibits poor flow properties and compressibility. Spherical crystallization of celecoxib was carried out using the solvent change method. An acetone:dichloromethane (DCM):water system was used where DCM acted as a bridging liquid and acetone and water as good and bad solvent, respectively. Hydroxypropylmeth…
Electroactive π-conjugated polymers have been synthesized by electrochemical polymerization of precursors consisting of two (3,4-ethylenedioxythiophene) (EDOT) groups linked by oligo(oxyethylene) chains of variable length. The analysis of the cyclic voltammetric behavior in the presence of various cations (Bu 4 N +, L…
Hydrogen thermal desorption analysis and TEM observation were performed to understand the relationship between microstructure and hydrogen absorption behavior in a V-bearing steel (0.4C-1.0Cr-0.7Mo-0.35V; mass%). The hydrogen absorption behavior was changed by controlling (V, X)C precipitation with change of tempering…
Linear wave propagation through a bubbly liquid has seen a resurgence of interest because of proposed "corrections" to the lowest-order approximation of an effective wave number obtained from Foldy's exact multiple scattering theory [Foldy, Phys. Rev. 67, 107 (1945)]. An alternative approach to wave propagation throug…
The chemical state of fluorine and the effect of fluorine addition on the degree of polymerization of silicate network have been investigated for the CaO-SiO2-CaF2 and CaO-SiO2-CaF2-FeOx glasses using the X-ray photoelectron spectroscopy (XPS) and Mössbauer spectroscopy measurements. The F1s XPS spectra indicate that…
