The thermal reaction of undecylenic acid with a hydrogen-terminated porous silicon surface takes place at 95°C to yield an organic monolayer covalently attached to the surface through Si-C bonds. The acid terminal group remains intact and is not affected by the chemical process. Under the same conditions, alcohols bre…

Regular octahedral coordination has been reported for some copper(II) complexes in the solid state on the basis of crystallographic studies, e.g. hexaaquacopper(II) bromate, [Cu(OH2)6](BrO3)2, hexaaquacopper(II) hexafluorosilicate, [Cu(OH2)6]SiF6, and hexakis(pyridine-1-oxide)copper(II) perchlorate, [Cu(ONC5H5)6](ClO4…
The performance of a solid oxide fuel cell (SOFC) with the configuration, 3 wt % Pd-loaded FeO|25 mol % -doped air, was studied between 350 and 600°C. The BCY25 electrolyte showed higher ion conductivities than 8 mol % yttria-stabilized zirconia (YSZ) below 800°C and 20 mol % -doped ceria (SDC) below 600°C, thus havin…
A conformationally flexible, generation-2,3 poly(aryl ether) dendrimer favors quantitative cascade fluorescence resonance energy transfer without the appearance of undesired chromophore self-quenching interactions such as excimer formation.
A series of derivatives of 5,10,15,20-tetrakis-(4-N-methylpyridyl)-porphine, where one N-methyl group was replaced by a hydrocarbon chain ranging from C6 to C22, were characterized for their photophysical and photosensitizing properties. The absorption and fluorescence features of the various compounds in neutral aque…

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…

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…
