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…
Perylene derivatives are industrially important pigments used not only as colorants, but also as materials for optical disks and photoconductors for electrophotographic photoreceptors. These pigments cover a variety of shades in the solid state from vivid red, via maroon to black, although their molecular absorption s…
The FTIR spectra were measured for raw Uplands Sicala-V2 cotton fibers over a temperature range of 40-325 degrees C to explore the temperature-dependent changes in the hydrogen bonds of cellulose. These cotton-cellulose spectra exhibited complicated patterns in the 3800-2800 cm(-1) region and thus were analyzed by bot…
In the fabrication process of Ni / Y 2 O 3 ZrO 2 (YSZ) cermet anodes for solid oxide fuel cells, it has been found that sintering and reducing processes of the cermet anodes at high temperatures (1000 to 1400°C) cause significant grain growth and agglomeration of YSZ and in particular Ni particles. This paper report…
Aqueous dispersions of a regioregular polythiophene, bearing enantiomerically pure oligo(ethylene oxide) side chains, are obtained by injecting small volumes of a THF solution of the polymer into water. The interplay of hydrophilic and hydrophobic interactions accounts for the unprecedented formation of hexagonal plat…
Diethyl fumarate and propylene glycol were reacted in the presence of a zinc chloride catalyst to synthesize poly(propylene fumarate) (PPF) over a period of 12 hours. The kinetics of the transesterification polymerization at 130 degrees C, 150 degrees C, and 200 degrees C were determined by gel permeation chromatograp…
The effect of trace boron in steels, especially the influence of boron on microstructure and properties of low carbon bainitic steels were summarized. It was pointed out that the hardenability of boron steels is determined by non-equilibrium boron segregation on grain boundaries. The synergistic effect of boron with o…
A dynamic covalent polymer incorporating thermally alkoxyamine units in the main chain was synthesized. Due to a radical crossover reaction between the alkoxyamine units, an interchange of the main chains in poly(alkoxyamine ester) was observed on heating.
Cobalt ferrite nanowires with an average diameter of 50 nm and lengths up to several micrometers were synthesized inside carbon nanotubes under mild reaction conditions using the confinement effect provided by the carbon tubular template.

The synthesis and properties of a novel set of building blocks for the preparation of self-assembling biomaterials are described. These molecules consist of a relatively short oligo( l -lactic acid) n̄ segment ( n̄ = 10−40) that is substituted with a cholesterol moiety as an end group and in some cases has a second bi…
