Polyaniline/α‐RuCl3.xH2O composites were successfully synthesized by an in‐situ chemical polymerization and employed as new electrode materials in supercapacitors. The synthesized composites were characterized physically by scanning electronic microscope (SEM). The electrochemical capacitance performance of these comp…
Electrochemical redox capacity of a microbial fuel cell (MFC) electrode is an important factor in the power density. This study was conducted to investigate the redox capacity of surface modified anode and cathode electrodes by measuring their conductivities. An anode electrode was modified with nitric acid and a cath…
This work deals with the water uptake and swelling behavior of magnetron-enhanced plasma-polymerized nanofilms in an aqueous medium. Those coatings are used in biomedical applications such as implants or contact lenses. The role of water in biomaterial surface science is considered to be of great importance. Water is…

Details concerning the limitations of this kind of predictions, as well as the justification of those inaccurate predictions shown in Figure 3, may be consulted in Cicero et al. (2012a). 3 PREDICTIONS OF APPARENT FRACTURE TOUGHNESS TheTCDs, in its different versions, allows the apparent fracture toughness (KIN) of any…

Vertically aligned zinc oxide (ZnO) hierarchical nanostructures were developed by homo-epitaxial growth method using nickel as catalyst, and their physical properties were investigated and reported. ZnO nanorods grown by vapor-liquid-solid method are single crystalline and grown along the 〈001〉 direction, whereas the…
Naturally occurring forms of materials have complex morphology and excellent performance, which provides new strategies for synthesising materials. In this paper, strontium oxalate crystals with different morphologies can be obtained simultaneously on either side of the membrane of mung bean sprouts (MBS). The as-obta…
We model organic field-effect transistors with Gaussian disordered energy distribution by a coupled three-dimensional steady-sate master equation and two-dimensional Poisson equation. By numerically solving these equations, we find that under moderate gate voltages the carrier distribution in the direction perpendicul…
The atomic structure, electron distribution, work function, and band structure of closed edge graphene are investigated with density functional theory. Field emission performance of closed edge graphene is compared with that of open edge graphene. We provide a possible explanation for the field emission microscopy ima…
Significant intergranular (IG) crack growth during stress corrosion cracking (SCC) tests has been documented during tests in simulated PWR primary water on two alloy 152 specimens cut from a weldment produced by ANL. The cracking morphology was observed to change from transgranular (TG) to mixed mode (up to ~60% IG) d…
Recently, structural biology witnessed a major tool - electron microscopy - in solving the structures of macromolecules in addition to the conventional techniques, X-ray crystallography and nuclear magnetic resonance (NMR). Three dimensional transmission electron microscopy (3DTEM) is one of the most sophisticated tec…
Catalytic activities of sonochemically prepared Au-core/Pd-shell-structured bimetallic nanoparticles (NPs) immobilised on TiO2 were evaluated. Comparing with the mixture of monometallic Au and Pd NPs on TiO2, core/shell-immobilised catalysts exhibited higher activities for the partial reduction of nitrobenzene (NB) to…
The present investigation deals with response of the particle size of aluminum on the reactive sintering of Ti–Al intermetallics and subsequently on their reaction kinetics and densification behavior. Aluminum powders of initial average particle size of 44 μm were milled for various durations in a planetary ball mill…
PURPOSE: Material decomposition using multienergy photon counting x-ray detectors (PCXD) has been an active research area over the past few years. Even with some success, the problem of optimal energy selection and three material decomposition including malignant tissue is still on going research topic, and more syste…
We propose here to investigate the non-equilibrium viscosity of Ge-Se glasses under and after light irradiation. Ge10Se90 and Ge20Se80 fibers have been aged in the dark and under ambient light, over months. During aging, both the relaxation of enthalpy and the viscosity have been investigated. The viscosity was measur…
Capsaicinoid, a naturally occurring alkaloid group and active components which can be found in chili peppers variety (Capsicum spp.), contributes to the pungency, taste, and aroma of chili peppers. Apart from their culinary and medicinal properties, capsaicinoid functions as antioxidant agent in food preservation. In…
Abstract Two 5‐methyl‐tetrazolate (mtz–)‐based paramagnetic metal coordination polymers, {[Cu2(H2O)2(mtz)(μ3‐OH)(nip)]·H2O}n (1) and [Cu(H2O)(mtz)2]n (2), were obtained in the presence and absence of aromatic 5‐nitroisophathalate (nip2–) coligand by varying the preparation methods. Structural determinations reveal tha…
Impurities such as sulfur compounds cause performance degradation in solid oxide fuel cells (SOFCs). We have studied the sulfur poisoning mechanism on an SOFC nickel anode using density functional theory method, focusing on the effects of surface and subsurface sulfur atoms. The binding energy of surface sulfur atoms…
In the present paper a new miospore genus Anabaculites is described from the glacial deposits of San Gregorio Formation of Northern Uruguay, considered of Upper Carboniferous age; however, the author's opinion is that they probably are of Permian age. The genus is referred to the Infraturma Apiculati.
