Magnetorheological fluids (MRFs) show a high but reversible rise of the viscosity upon application of an external magnetic field. This effect can be utilized in controllable friction dampers where the MR fluid flows through a gap with a adjustable magnetic field. The change in the magnitude of the magnetic field leads…
There is often a need to perform rheological tests on dilute polymeric liquids at a time long after their initial preparation, for example if a more sensitive or novel method of measuring a material property (such as uniaxial/biaxial extensional viscosity or second normal-stress differences) becomes available. An inex…
The calibration of the temperature control unit of a rotational rheometer with a hood oven is shown. The calibration technique shown for a Paar-Physica rheometer can be adapted to any rheometer with hood oven (indirect heating). The temperature of the bottom fixed plate and the air bearing suspended cone or plate are…
This paper investigates some physical properties of pile loop knit fabrics. Several fabric parameters, such as pile type (pile loop and cut-pile loop fabrics), fiber type (100% cotton and 50/50% cotton/lyocell blend), fabric tightness (slack, medium, and tight), relaxation (dry relaxation and wash and dry relaxation),…
This paper presents a model for three-phase power transformers for electromagnetic transient studies, which employs a wavelet filter bank. In this model, both the primary and the secondary windings are represented by stages of a wavelet filter bank, where each turn is represented by one complete stage. The sum of resp…
Layer-by-layer self-assembled polyelectrolyte shells are a new class of micro/nanocapsules with unique physicochemical properties for potential applications in drug/gene delivery. The objective of this study was to investigate the interactions of polyelectrolyte shells ( approximately 1 mum in diameter) with MCF-7 bre…
A novel super-compact multilayered (ML) composite-right/left-handed (CRLH) transmission line (TL) is proposed. This ML architecture consists of the periodic repetition of pairs of U-shaped parallel plates connected to a ground enclosure by meander lines. The parallel plates provide the left-handed (LH) series capacita…
This paper reports an analysis of the changes in the photoemission parameters of copper in small particles of copper oxides deposited on silicon dioxide. This study is of relevance for investigations in the fields of heterogeneous catalysis and coordination chemistry. Copper oxides (Cu2O and CuO) have been deposited o…
The hybrid plasma-catalyst system represents an effective method for the pollutant abatement from car exhaust. A problem, however, is a limited volume of the generated plasma, and a pressure drop across the catalyst layer. A new approach on the generation of microdischarges inside porous ceramic materials is reported.…
Abstract The interest in poly(L‐lactic acid)(PLLA) has been increasing in recent years because this polymer is made from renewable resources and its properties are benign to the environment. Carbon nanotubes(CNTs) have shown exceptional stiffness and strength and remarkable thermal and electrical properties, which mak…
This paper presents a new, simple and low cost method to reduce inrush currents caused by transformer energization. The method uses a grounding resistor connected at a transformer neutral point. By energizing each phase of the transformer in sequence, the neutral resistor behaves as a series-inserted resistor and ther…
A novel point-arc microwave plasma chemical vapor deposition (CVD) apparatus was employed to grow single-walled carbon nanotubes (SWNTs) on Si substrates coated with a sandwich-like nano-layer structure of 0.7 nm Al 2 O 3 (top)/0.5 nm Fe/5–70 nm Al 2 O 3 by conventional high frequency sputtering. The growth of extreme…
Ferromagnetic nanowires are shown to perform both high yield and high purity single-step cell separations on cultures of NIH-3T3 mouse fibroblast cells. The nanowires are made by electrochemical deposition in nanoporous templates, permitting detailed control of their chemical and physical properties. When added to fib…
Various examples of composite titania-based nanostructured materials exhibiting cooperative functionalities between different active components are presented. The fabrication of these integrated composite materials is based on one-pot supramolecular templating techniques combined with acidic sol-gel chemistry. The def…
The φ110 mm bar products of steel 3Cr2W8V were forged from 740 kg ingot melted by 15 t EAF and re- fined by 25 t LF. At end of refining period,the oxygen content in steel was 29×10-6and the liquid steel was treated by rare earth treatment with adding 0.048% RE alloy(21~24RE,44Si,3Mn,5Ca,3Ti,bal Fe). The yield of rare…
It is available for Consarc ESR furnace through control of swing voltage to keep the distance between electrode and slag surface unchanged,in order to keep the shape of remelting pool unchanged during remelting and get high quality ESR ingot. Based on analysis of voltage swing control principle for Consarc ESR furnace…
