The rolling bearings operate in very different co nditions. The selection of lubricant and the lu- brication system is a complex and very important pr oblem. Besides the main function of reducing the friction, a lubricant removes the heat, withstands to the high pressures, ensures the sealing of the c ou- plings, carr…
( , 0.4, 0.6) sample is determined to be cubic spinel with space group -3 m by Rietveld refinement. The lattice constant increased linearly with the Cu concentration from to 0.6. With increasing Cu concentration, the saturation magnetization and coercivity decreased from 101.3 emu/g, 112 Oe to 88.7 emu/g, 83 Oe, respe…
A draft updated code of building fire safety in Hong Kong was just released in end September 2011. Effect of smoke toxicity on tenability limits was not yet specified clearly. Only temperature of smoke layer, visibility and carbon monoxide concentration were mentioned on specifying smoke effect on tenability limits. T…
The Office of Waste Processing within the DOE EM Office of Technology Innovation and Development manages technology development and maturation to advance the treatment and disposition of high-level and low-level radioactive liquid wastes. Most of these wastes and associated facilities are unique to the DOE, meaning ma…
Barium Zirconate BaZrO3 fine powders were prepared by oxalate method using BaCl2.2H2O, TiCl4 and oxalic acid as starting materials. The precursor (BaZrO(C2O4)2.xH2O) has been synthesized and characterized by combination of spectroscopic and thermal analysis. The precursor under goes thermal decomposition, in two major…
The 2000 Complex at the Oak Ridge National Laboratory (ORNL) was decontaminated and decommissioned (DD structural demolition; waste management and disposal; and site restoration. At completion of major field activities in December 2010, eight facilities were demolished (approximately 5,715 m 2 or 61,500 ft 2 ), genera…
The central building of the Hungarian Academy is located on the riverside of Danube in Budapest. It was constructed in between 1865 and 1872. In the past nearly hundred-fifty years the building has suffered from war damages and has been restored several times. The facade of the building was mostly built of porous Mioc…
A variety of antennas have been engineered with metamaterials (MTMs) and metamaterial-inspired constructs to improve their performance characteristics. Examples include electrically small, near-field resonant parasitic (NFRP) anten- nas that require no matching network and have high radiation efficiencies. Experimenta…
The effect of process residence time, set temperature and drying time on the rheological and mechanical properties of a commercially available starch based polymer blend is reported. Capillary rheometry was used to measure the rheology, melt strength and time-dependent degradation of the polymer. Tensile specimens wer…
Control of wetting properties has been investigated for applications in diverse fields, from microfluidics to contamination prevention. We present a robust, rapid, and reproducible superhydrophobic surface with hierarchal nano- and microscale structures molded into polydimethylsiloxane (PDMS). This method involves a p…
In this paper, we review several transformation-optics and illusion-optics devices realized by microwave metamaterials, including three-dimensional (3D) ground-plane cloak, 3D Luneburg lens with flattened focal surface, two-dimensional (2D) shrinking device, and 2D material-convention device. Experiments demonstrate g…
In this paper we have reported a mechanism which corrects Fermi level of Single Wall Carbon NanoTubes (SWCNT). We solved Boltezman equation for electron-phonon scattering to obtain electron-phonon distribution function. After that we renormalized distribution function in presence of electric field then we calculated S…
This paper describes the 300-year performance demonstration in the Renewal Application for the Hazardous Waste Facility Permit for the Waste Isolation Pilot Plant (WIPP) and compares the methodology for and results from the demonstration to: (i) the previous 300-year performance demonstration from the initial permit a…
The corrosion inhibitor of carbon steel in 1% NaCl solution by curcuminoids has been studied at 27 o C using weight loss and electrochemical method. The determination of corrosion inhibition efficiency (%eff) utilising weight loss method at the concentration of 80 ppm showed the best result of 78.70% for third isolate…
We present our research into the modeling and fabrication of three-dimensional (3D) nanostructures by direct laser writing, using an organic-inorganic hybrid polymer that can be selectively covered with metal. This material exhibits low shrinkage when structuring, metal binding affinity and ohmic conductivity when cov…
Summary Present study is undertaken to evaluate the antidiabetic potential of Methanolic extract of Leptadenia pyrotechnica (MELP) against streptozotocin induced diabetic rat. The extract exhibited the dose dependent lowering of blood glucose level in diabetic rats. Elevated serum cholesterol and triglyceride level we…

Brass alloy C 26000 containing zink 30% is susceptible to dezincification. Since zinc metal is much more active than copper metal, zinc dissolves and leaves porous copper metal during dezincification of the alloy. This form of corrosion can occurs at both outside and inside crevices. The dezincification of the alloy c…
Introduction Nematic liquid crystal (NLC) is anisotropic at its nematic phase and serves as an anisotropic matrix for colloidal dispersions. Colloidal particles form distinctive structures in NLC [1-3] and remarkably modify properties of NLC [4]. In this experiment, scanning microbeam wide-angle X-ray scattering (WAXS…
Polymer nanocomposites containing well dispersed layered nanofiller represent new class of unique light weight materials by combining the flexibility of polymers with the high modulus inorganic component bringing many synergetic effects, e.g., significantly enhanced inflammability. At the same time, the high surface a…
