Due to the large amount of electrical equipment and the costs of an individual diagnosis in distribution networks, a life assessment of the representative electrical components is necessary. For a thorough electro-thermo-mechanical life model of the electrical components, the individual aging phenomena of the represen…
Advances in nanotechnology have led to the development of novel fluorescent probes called quantum dots. Quantum dots have revolutionalized the processes of tagging molecules within research settings and are improving sentinel lymph node mapping and identification in vivo studies. As the unique physical and chemical pr…
The thermal resistances of 1250 kinds of interface were computed at room temperature based on the phonon diffuse mismatch model. The result shows that the ratio of Debye temperature and the ratio of average sound velocity can be approximately used to characterize the difference of two materials in terms of interfacial…
The influence of hydrophilic silica nanoparticles on the emulsification of a triglyceride oil (Miglyol812) in the presence of charged surfactants (lecithin or oleylamine) and the long term stability of the resultant oil-in-water emulsions are reported. A synergistic effect of nanoparticles and surfactants in improving…
Until recently it was believed that extracellular gadolinium based contrast agents were safe for both the kidneys and all other organs within the dose range up to 0.3 mmol/kg body weight. However, in 2006, it was demonstrated that some gadolinium based contrast agents may trigger the development of nephrogenic systemi…
This series of papers presents details of numerical studies of the nature of the impedance of solid oxide fuel cell ͑SOFC͒ anodes caused by gas-phase transport processes.The present part treats channel geometries where gases are transported parallel to the electrode surface.Two cases are investigated: ͑i͒ channel flow…
In the present work we report on the growth, spectroscopy and laser results of LiLuF(4):Pr(3+) 1.25% in the melt. Room temperature polarized absorption and emission spectra have been recorded and the decay time of the (3)P0 manifold has been measured. Finally efficient room temperature laser emission have been obtaine…
We investigated the decomposition and (partial) oxidation of methanol on Pd based catalysts in an integrated attempt, simultaneously bridging both the pressure and the materials gap. Combined studies were performed on well-defined Pd model catalysts based on ordered Al(2)O(3) and Fe(3)O(4) thin films, on well-defined…
Two examples of a new class of functional nanocomposites derived from cellulose nanofibers (referred to as “whiskers”) and (semi)conducting π-conjugated polymers were prepared and studied. The conjugated polymers used were polyaniline (PANI) and a poly(p-phenylene ethynylene) (PPE) derivative with quaternary ammonium…
We observed the atomic structures for each reset and set state in a phase-change random access memory fabricated using stoichiometric crystalline . The reset state clearly showed a mixture of dome-shaped amorphous and crystal structure surrounding amorphous, but the set state showed abnormally grown large grains due t…
This paper describes the synthesis of highly water-soluble and fluorescent ZnSe(S)-alloyed quantum dots (QDs). We used zinc perchlorate hexahydrate, sodium hydrogen selenide as precursors and mercaptopropionic acid as stabilizer to synthesize ZnSe QDs in aqueous solution at 160 °C for 9 h. The as-prepared ZnSe QDs pos…
BACKGROUND: Conventional cell culture studies have been performed on 2D surfaces, resulting in flat, extended cell growth. More relevant studies are desired to better mimic 3D in vivo tissue growth. Such realistic environments should be the aim of any cell growth study, requiring new methods for culturing cells in vit…
Nanoparticles of metals such as Au, Ag, Pd and Pt embedded in exfoliated sheets of aminoclays of the type R8Si8Mg6O16(OH)4, where R = CH2CH2NH2 are entirely water soluble. These sheets of the composite come to the organic-aqueous interface on addition of alkane thiols to the aqueous layer.
This tutorial review covers recent progress in the field of computer simulation of liquid crystals. The development of the main "molecular-based" models for liquid crystals is described. These include lattice models, coarse-grained single site models based on hard and soft interaction potentials, atomistic models and…
Catalytic ammonia oxidation over platinum has been studied experimentally from UHV up to atmospheric pressure with polycrystalline Pt and with the Pt single crystal orientations (533), (443), (865), and (100). Density functional theory (DFT) calculations explored the reaction pathways on Pt(111) and Pt(211). It was sh…
Ordered mesoporous carbon containing molecular-level dispersed Pd clusters in the carbon walls can be synthesized by the nanocasting pathway, which shows high selectivity for the oxidation of alcohols to aldehydes.
Smectites or swelling clay minerals are naturally occurring nanomaterials that can be fully delaminated to elementary clay mineral platelets in dilute aqueous dispersion. This review article gives an overview of the recent progress on how the elementary clay mineral platelets can be reorganized in monolayered or multi…
A transparent superhydrophobic TiO2 film, prepared by spin-coating a TiO2 slurry on a glass substrate and modifying the resultant TiO2 film with fluoroalkylsilane molecules, was patterned by illumination with ultraviolet light through a photomask, producing a superhydrophobic/superhydrophilic surface micropattern with…
An important measuring technique under study for the DARWIN planet finding mission, is nulling interferometry, enabling the detection of the weak infrared emission lines of an orbiting planet. This technique requires a perfect wavefront of the light beams to be combined in the interferometer. By using a single mode wa…
Numerical methods were used to calculate the influence of geometry-induced current and potential distributions on the impedance response of a blocking disk electrode with a local constant-phase element behavior. While the calculated global impedance is purely capacitive, the local impedance has high-frequency inductiv…
