Bacterial adhesion on stainless steel may cause problems such as microbially induced corrosion or represent a chronic source of microbial contamination. The investigation focussed on how the extent and patterns of four bacterial species comprising three different phyla and a broad variety of physicochemical characteri…
Abstract The Raman spectra of the three varieties of hydrated calcium carbonate, monohydrate, hexahydrate and ‘amorphous,’ are reported for the first time and discussed according to the already known crystal structures. The transformation by dehydration of these hydrated phases into the usual anhydrous forms was follo…
The magnetism and the electronic structure of II–VI compound-based diluted magnetic semiconductors (DMSs) are investigated based on ab initio calculations. The stability of the ferromagnetic state in ZnO-, ZnS-, ZnSe- and ZnTe-based DMSs is investigated systematically and materials design for ferromagnetic DMSs is giv…
In order to enhance energy density, a hybrid type pseudocapacitor/electric double layer capacitor (EDLC) was considered and its electrochemical properties were investigated. At various current densities, stable charge/discharge behaviors were observed with much higher specific capacitance values of 530 F/g compared wi…
A crucial factor in tissue engineering of heart valves is the functional and physiologic scaffold design. In our current experiment, we describe a new fabrication technique for heart valve scaffolds, derived from x-ray computed tomography data linked to the rapid prototyping technique of stereolithography. To recreate…
Abstract A focus of frontline interdisciplinary research today is the development of the conceptual framework and the experimental background of the science of nanostructured materials and the perspectives of its technological applications. We consider some current directions in the preparation, characterization, mani…
ABSTRACT: Whey protein isolate (WPI)‐based edible biopolymer films were prepared using a film‐forming stage designed to provide heat‐induced gelation. Effects of whey‐protein ratios, calcium, glycerol (plasticizer), and emulsion droplet incorporation on film tensile and barrier properties were investigated. Protein ra…
MoO3-x samples were prepared under different temperature and gas atmosphere conditions. The samples, which are all of the crystallographic MoO3 structure, have been investigated by XRD, SEM, diffuse reflection (DR) UV/VIS and Raman spectroscopies to characterize their properties as a function of the different concentr…
The electrical conductivity of containing rare earth dopants (Y, La, Pr, Sm, Nd, Gd, or Yb) was measured at 600-900°C in reducing atmospheres. An unusually high conductivity was observed for the yttrium-doped samples compared to those with rare earth dopants, particularly at the composition of the solubility limit whe…
To separate anode and cathode contributions to the impedance of a thin solid electrolyte cell, many workers place a reference electrode on the surface of the inactive electrolyte, coplanar with the working electrode. This practice is evaluated theoretically using finite-element calculations of the real and imaginary p…
Determination of Oxygen Vacancy Concentration in a Thin Film of La0.6Sr0.4CoO3 − δ by an Electrochemical Method , Kawada, T., Suzuki, J., Sase, M., Kaimai, A., Yashiro, K., Nigara, Y., Mizusaki, J., Kawamura, K., Yugami, H.
Fe–Ga alloys, in which the α-Fe structure is maintained, are rich sources of high strength, low cost magnetostrictive alloys for transducer and vibration reduction applications. Although the magnetostriction of Fe itself is very low, when a relatively small fraction of the Fe atoms are replaced by Ga, the magnetostric…
We report a simple method to synthesize binary polymer brushes from two incompatible polymers of different polarity. The synthetic route is based on a subsequent step-by-step grafting of carboxyl-terminated polystyrene and poly(2-vinylpyridine) to the surface of a Si wafer functionalized with 3-glycidoxypropyl-trimeth…
In this paper, the processes associated with the electrodeposition of bismuth telluride ( Bi 2 Te 3 ) , a thermoelectric material, are reported along with an analysis of the composition and crystallinity of the resulting films. The electrodeposition can be described by the general reaction 3 HTeO 2 + + 2 Bi 3 + + 18 e…
A series of pentadecanuclear lanthanide-hydroxo complexes possessing a common core of the formula [Ln(15)(mu(3)-OH)(20)(mu(5)-X)](24+)(1, Ln = Eu, X = Cl(-); 2, Ln = Nd, X = Cl(-); 3, Ln = Gd, X = Cl(-); 4, Ln = Pr, X = Br(-); 5, Ln = Eu, X = Br(-)) were prepared by L-tyrosine-controlled hydrolysis of corresponding la…
A detailed study was made of cellular and extracellular production of carbohydrates and amino acids by the marine diatom Skeletonema costatum (Grev.) Cleve during different growth phases. Batch cultures were run with a 14:10 h light:dark cycle in N-limited media at 2 different nutrient strengths. The exponential growt…
The NIST Electron Effective-Attenuation-Length Database provides values of electron effective attenuation lengths (EALs) in solid elements and compounds at selected electron energies between 50 eV and 2, 000 eV. The database was designed mainly to provide EALs (to account for effects of elastic-electron scattering) fo…
Abstract Low-temperature plasma technologyboth glow discharge under reduced pressure as well as barrier discharge under normal pressureare well established in different industrial applications. Since recently, however, the plasma technology is being introduced in textile industry as well. Fields of application are des…
