In general, melting process is not a common method for the production of oxide dispersion strengthened (ODS) alloys due to agglomeration and coarsening of oxide particles. However, vacuum casting process has recently been employed as a promising process to produce micro-scale oxide dispersed alloys. In this paper, we report the process and characterization of in situ formation and uniform dispe...

Graphene, a two-dimensional honeycomb lattice of sp 2 hybrid carbon, exhibit combination of unique characteristics such as high thermal and electrical conductivity, excellent mechanical strength and very high specific surface area, which promises their great potential for various applications including nanoelectronics, catalysis, sensors, energy storage devices, polymer composites, lubricants a...

PURPOSE To evaluate spin-lock MR for detecting superparamagnetic iron oxides and compare the detection sensitivity of quantitative T1ρ with T2 imaging. METHODS In vitro experiments were performed to investigate the influence of iron oxide particle size and composition on T1ρ . These comprise T1ρ and T2 measurements (B0 = 1.41T) of agar (2%) with concentration ranges of three different iron ox...

abstract this work investigated the electrochemical and aqueous tribological behavior of hot pressed 2205 duplex stainless steel (dss). dss sintered composites of different volume percent (% vol) of partially stabilized zirconia (psz) was developed using powder metallurgy (pm) technique. electrochemical behaviour was studied at room temperature, using open circuit potential and potentiodynamic ...

A systematic capacitance-voltage study has been performed on GaAs metal-oxide-semiconductor MOS structures with atomic-layer-deposited HfO2/Al2O3 nanolaminates as gate dielectrics. A HfO2/Al2O3 nanolaminate gate dielectric improves the GaAs MOS characteristics such as dielectric constant, breakdown voltage, and frequency dispersion. A possible origin for the widely observed larger frequency dis...

nanosized metal oxides dispersed polymer composites constitute a fascinating class of polymer composite materials. synthesis of such composite materials through solvent casting enhances the polymer synthetic technology. solvent casting method was used to prepare cobalt oxide (co3o4) dispersed poly (methyl methacrylate) (pmma) nano composite. x-ray diffraction tool is used to know the structural...

The objective of this study is to carry out a parametric sensitivity analysis of PHAST atmospheric dispersion modelling for an accidental toxic gas release scenario. A methodology is developed and is applied to a nitric oxide gas dispersion scenario. We study the relative influence of uncertainty in independent input parameters (storage conditions, atmospheric variables, release parameters and ...
