A Metal-Insulator-Metal (MIM) device based on a Cu2O insulator has electrical characteristics significantly dependent on the oxide to top electrode (TE) interface. Cu/Cu2O/TE devices with various top electrodes have different thermal release characteristics, related to trap depth. The behavior of the device during era…
BSCF hollow fiber membranes possessing an asymmetric layered structure were prepared using a modified phase inversion process followed by subsequent sintering at temperatures from 1100 to 1175 ˚C. The fibers were characterized by SEM, and tested for air separation at ambient pressure and temperatures between 650 and 9…
Several difluoroisothiocyanato‐based biphenyl tolanes exhibiting high optical birefringence are presented and their representative molecular structure is shown below. The optical birefringence of these liquid crystals lies between 0.44 to 0.48. Several eutectic mixtures of the biphenyltolanes with other compounds have…
Gold nanoparticle-dendrimer conjugate clusters were prepared by a covalent coupling of monofunctional gold nanoparticles with a generation 5 PAMAM dendrimer.
First demonstration of AC gain from a single-walled carbon nanotube transistor is presented. A top-gated carbon nanotube field-effect transistor (CNFET) is configured as a common-source amplifier and frequency response function of the amplifier is measured. Evidence of unambiguous signal amplification is observed in t…
The propagation of the long-range surface plasmon-polariton mode in waveguides comprised of a curved thin metal film of finite width embedded in a homogeneous background dielectric is described. The curve and its mode are modelled in cylindrical coordinates using a rigorous vectorial numerical method and an absorbing…
The strengths of epoxy/aluminum joints reinforced with a zirconium-silicon based sol–gel adhesion promoter were investigated using an ADCB (Asymmetric Double Cantilever Beam) wedge test. The fracture energies and loci of failure of these joints were shown to depend upon the mixity of the normal and shear modes of stre…
The decreasing availability of energy and concern about climate change necessitate the development of novel sustainable energy sources. Fusion energy is such a source. Although it will take several decades to develop it into routinely operated power sources, the ultimate potential of fusion energy is very high and bad…
Henequen natural fiber-reinforced poly(butylene succinate) biocomposites were prepared through a resin microdroplet formation on a single fiber and also fabricated by a compression molding technique using chopped henequen fibers, surface-treated with electron beam irradiation (EBI) at various dosages. The effect of EB…
A novel, non-aqueous organometallic access to colloidal copper and copper/zinc (brass) nanoparticles is described. Hydrogenolysis of the precursor [CpCu(PMe3)] (1) in mesitylene at 150 °C and 3 bar H2 quantitatively gives elemental Cu. Analogously, a solution of [ZnCp*2] (2) reacts with H2 to give elemental Zn in 100%…
Machined chips of a magnesium ally were repeatedly recycled by hot extrusion at 673 K, and mechanical and corrosion properties of the recycled specimens were investigated. At room temperature, the recycled specimen with a high repeated number showed high 0.2% yield stress and high tensile strength but low elongation a…
The maximum electrical conductivities in polycrystalline Cu interconnects with sub-100nm linewidth were extrapolated from the measured resistivities of the Cu interconnects with various linewidths (100–1000nm) using a Mayadas–Shatzkes (MS) model. These polycrystalline Cu interconnects with TiN cap layers were fabricat…
The effect of equal-channel angular pressing (ECAP) on the pitting corrosion resistance of Al and Al-Mg alloy was investigated by means of polarization curves in solutions containing 300 ppm of Cl− and by surface analysis. The potentials for pitting corrosion of Al and Al-Mg alloy were clearly shifted in the noble dir…
Bioconjugation of a highly fluorescent water-soluble poly(para-phenyleneethynylene) (PPE) copolymer with ionic and non-ionic side chains is achieved by means of chain-end modification, providing a design principle for biosensor development.
Our objective was to evaluate the chemotherapeutic potential of oral poly lactide-co-glycolide (PLG, a synthetic polymer) nanoparticle encapsulated ethambutol in combination with PLG-nanoparticle encapsulated-(rifampicin + isoniazid + pyrazinamide) in a murine tuberculosis (TB) model. Our formulation was prepared by t…
The uniaxial alignments of the columnar superstructure of discotic metallomesogens, cobalt octa(n-dodecylthio)porphyrazine (CoS12), over the centimetre length scale have been achieved by spinning samples under a static magnetic field. The orientations of the columnar superstructures were investigated by small angle ne…
We report the design, synthesis and characterization of new benzothiadiazole- and pyrrole-based copolymers whose solubility and bandgap drastically change after thermal treatment of their thin films.
The new borazine derivative [B{CH(CH3)(SiCl3)}NH]3 (TSEB) was prepared by reacting Cl3Si–CH(CH3)–BCl2 (TSDE) with hexamethyldisilazane (hmds) at ambient conditions. TSEB was characterized by infrared spectroscopy (IR), nuclear magnetic resonance (NMR), and by mass spectrometry (MS). The specially designed molecule ser…
Equilibrium distributions of multicomponent systems minimize the free energyfunctional under the constraint of mass conservation of the components.However, since the free energy is not convex in general,usually one tries to characterize and to construct equilibrium distributionsas steady states of an adequate evolutio…
The chemical stability of the interface of lanthanum strontium iron cobalt oxides (LSCF) and lanthanum strontium magnesium gallium oxide (LSGM) was investigated. LSCF and LSGM do not coexist stably, and it makes solid solutions at higher temperatures by the fast interdiffusion of metal components. The bulk and grain b…
