We have proposed a unified approach to the modeling and study of developments in the field of MEMS and Nanotechnology and its application in futuristic Nano-enabled Cells. We have proposed a novel to approach reliability of MEMS enabled fuel cells. We know that reliability and accurate prediction of properties in nano domains remains a major challenge where still theories are being developed to...

We present a method for direct three-dimensional (3D) patterning of porous nanomaterials through the application of a premastered and reusable gray-scale stamp. Four classes of 3D nanostructures are demonstrated for the first time in porous media: gradient profiles, digital patterns, curves and lens shapes, and sharp features including v-grooves, nano-pits, and 'cookie-cutter' particles. Furthe...

mirage effect is contactless and non destructive method which has been used a lot to determine thermal properties of different  kind of samples , transverse photothermal deflection ptd in  skimming configuration with ccd camera  and special programs is used to determine thermal conductivity of porous silicon ps  film. ps samples were prepared by electrochemical etching. thermal conductivity wit...

A novel generic method of silica supported catalyst system generation from a fluid state is presented. The technique is based on the combined flow and radiation (such as microwave, thermal or UV) induced co-assembly of the support and catalyst precursors forming nano-reactors, followed by catalyst precursor decomposition. The transformation from the precursor to supported catalyst oxide state c...

Biodegradable polymers have been widely used as scaffolding materials to regenerate new tissues. To mimic natural extracellular matrix architecture, a novel highly porous structure, which is a three-dimensional interconnected fibrous network with a fiber diameter ranging from 50 to 500 nm, has been created from biodegradable aliphatic polyesters in this work. A porosity as high as 98.5% has bee...

Using nano-hydroxyapatite/polyamide66 composite (n-HA/PA66) and a special foamer as start materials, a porous species for bone defect repair was successfully developed by thermal-pressing method. The resulting material presented: (1) high compressive strength which reached 13~46MPa; (2) excellent porous structure, the average diameter of pores in the matrix was in range of 280μm to 500μm and po...

Flexible membranes created from porous carbon nanofibers (CNFs) hold great promise in the next generation wearable energy storage devices, but challenges still remain due to the poor mechanical properties of porous carbon nanofibers. Here, we report a facile strategy to fabricate elastic and hierarchical porous CNF membranes with NiFe2O4 nanocrystals embedded via multicomponent electrospinning ...

The present paper briefly reviews the development progress of solid-liquid phase change materials, particularly nano-porous shape-stabilized materials. We outline designs and syntheses heat storage functional materials thermophysical mechanism loading, crystallization, thermal transport in nano-confined space. Besides, remarkable methods to enhance release performance heterogeneous are included...

The solvothermal reaction of Co(NO(3))(2) and 2,4,6-tris(4-pyridyl)-1,3,5-triazine in dimethyl-formamide/ethanol mixed solvent afforded the title coordination polymer, [Co(NO(3))(2)(C(18)H(12)N(6))](n), in which the Co(II) atom is seven-coordinated by pyridyl groups of three different ligands and two chelating nitrate anions. The complex displays a nano-sized porous metal-organic framework that...

The present research examines the unsteady isothermal ow of a gas through a semi-in nite micro-nano porous medium, a nonlinear boundary value problem on semi-in nite interval. This problem is solved by two di erent methods and compare their results with solution of other methods is compared. Also through the convergence of these methods, the accurate initial slope y(x) with good capturing the e...
