The effect of aging on the dielectric strength of epoxy-inorganic particle composites used for insulators in the high voltage industry is reported. A differential scanning calorimetry analysis of an insulator aged twenty years in actual service conditions indicated both a chemical degradation and a structural recovery…
Abstract The selective hydrogenation of cyclic and acyclic dienes to monoolefins occurs under very mild conditions, in the presence of silica‐supported PAMAM‐Pd complexes. The activity and selectivity of this reaction is sensitive to the dendrimer structure. These dendritic complexes display excellent recycle properti…
This study ranks the contribution of various fibre, yarn and fabric attributes to the pilling of wool knitwear. On the basis of an artificial neural network modelling, a combination of sensitivity analysis, forwards/backwards search and genetic algorithms was used to identify the importance of various fibre/yarn/fabri…
The synthesis of magnetic nano sized Fe particle-encapsulated single-walled carbon nanotubes (SWNTs) has been realized for the first time by a two-step method. In this method, ferrocene is selected as a starting material and used in filling SWNTs. Then, the as-synthesized ferrocene-filled SWNTs are decomposed to relea…
The photophysical properties and the nature of the photoinduced electron transfer (PET) reactions within a synthesized anisole (A)-thioindoxyl (T) dyad system (24MBTO) have been studied by electrochemical, steady-state, and time-resolved spectroscopic techniques. Computations on the dyad were performed both in gas pha…
Abstract The performance of anode‐supported cells with a composite LSM‐YSZ cathode and an LSM current collector was investigated. Over the first 48 hours, after the application of a constant current, the cell voltage was observed to increase by up to 20%. When the current was switched off, the cell resistance increase…
We present the design of a sample holder for small-angle x-ray scattering (SAXS) that can be used for both static and flow cell measurements, allowing to switch between these two types of measurement without having to realign the detector and camera geometry. The device makes possible high signal-to-noise experiments…
We demonstrated ultrasensitive detection of ozone using single-walled carbon nanotube (SWNT) networks directly grown on a conventional sensor substrate. Ozone was detected down to the ppb level (∼6 ppb) at room-temperature operation with a fast response. Using an electrical breakdown technique, gas sensitivity was imp…
The electromigration resistance of ultra-large scale integration (ULSI) Cu interconnects can be improved by inserting an adhesion promoter between Cu and the diffusion barrier. A metallurgical survey was accomplished to select the element having a good Cu adhesion property. For adoption as an interconnect material, it…
Wool fabric was treated with low temperature plasma (LTP) with a non-polymerizing gas, namely oxygen. After the LTP treatment, the properties of the fabric, including low-stress mechanical properties, air permeability and thermal properties, were studied. The low-stress mechanical properties obtained by the means of K…
Insulating materials exist in a variety of different forms, including gas, liquid, solid, and vacuum, and different forms of insulating materials have significantly different dielectric strengths and insulating properties. Power transmission/substation facilities for UHV AC and 500 kV DC power transmission and 500 kV…
ABSTRACT: The antimicrobial effect of konjac glucomannan (KGM) edible ûlm incorporating chitosan (CHI) and nisin at various ratios or concentrations was studied. This activity was tested against pathogenic bacteria, namely, Escherichia coli, Staphylococcus aureus, Listeria monocytogenes , and Bacillus cereus. Mechanic…
Abstract A series of novel dendrimers composed of dendritic phenylazomethines (DPAs) were synthesized with several types of functional cores. The metal assembling to the DPAs is stepwise by the layers, therefore, they can be used as a scaffold for the precise hybridization between metal ions and organic macromolecules…
Eight-coordinate hydroxypyridinone/terephthalamide GdIII complexes display high relaxivities due to their two inner sphere water molecules. This relaxivity can be further increased by functionalizing the terephthalamide moiety with an amine. A significant hydrogen bonding interaction between the amine and another wate…
Abstract A controlled drug release has been obtained from hybrid organic–inorganic mesoporous silica carriers under in vitro conditions. The control of drug release rate can be ascribed to the incorporation of different hydrophobic functional groups.
Using the general coupled-mode formulation, it is shown that the interaction between a regular transmission line and a negative-refractive-index (NRI) line leads to complex coupled modes. Specifically the coupling between a regular microstrip (MS) and a NRI line is analyzed and the theory reveals conditions giving ris…
Previous studies have shown good adsorption of volatile organic compounds (VOC) present in air onto activated carbon fiber cloths (ACFCs). In a chemical plant, a treatment process was carried out to control a gaseous emission (flow close to 100 m3 h−1) loaded with methylene chloride at concentrations ranging between 3…
An advanced bottom electrode contact (BEC) was successfully developed for reliable high-density 256 Mb phase-change random access memory (PRAM) using a ring-type contact scheme. This advanced ring-type BEC was prepared by depositing very thin TiN films inside a contact hole, after which core dielectrics were uniformly…
The orientation of cellular alignment in smooth muscle tissue engineering is directly related to optimal movement of engineered tissue when it is transplanted in vivo. Cyclic mechanical strain has been applied to modulate the alignment, proliferation, and differentiation of smooth muscle cells. This study was conducte…
Modification of titanium via surface-initiated atom transfer radical polymerization (ATRP) was carried out. The surface of the titanium foil was activated initially by a silane coupling agent containing the ATRP initiator, benzyl chloride. Well-defined polymer brushes of poly(ethylene glycol) methacrylate (PEGMA), (2-…
