BACKGROUND Polymers are attractive materials for both biomedical engineering and cardiovascular applications. Although nano-topography has been found to influence cell behaviour, no established method exists to understand and evaluate the effects of nano-topography on polymer-blood interaction. RESULTS We optimized a micro-fluidic set-up to study the interaction of whole blood with nano-struc...

background: it has recently been shown that the particle size of materials used for radiation shielding can affect the magnitude of radiation attenuation. over the past years, application of nano-structured materials in radiation shielding has attracted attention world-wide. the purpose of this study was to investigate the shielding properties of the lead-free shields containing micro and nano-...

Abstract Lithium-ion batteries are the most suitable energy storage device for powering of electronic devices such as mobile, laptop, electrical vehicle etc. Electrical vehicles associated with green technology it reduces environmental pollution due to their low emission green-house gases. In this review I discussed about present and future battery technologies on basis working electrodes, nano...

An efficient and green protocol for the synthesis of pyrazoles derivatives by one-pot reaction of different 1,3-dicarbonyl compounds with hydrazines/hydrazides has been developed using nano-sulfated zirconia, nano-structured ZnO, nano-g-alumina and nano-ZSM-5 zeolites, as the catalyst. The optical properties of the nano-structured catalysts and organic molecules were studied. The advantages of ...

The micro and nano-structured amorphous carbon as p-type films prepared from natural palm oil precursor for heterojunction solar cell were presented. Field-emission scanning electron microscopy (FESEM) revealed the micro and nano structured films had particle size in the range of 382 nm to 689 nm and 28 to 34 nm, respectively. The energy-dispersive spectroscopy (EDS) showed the existing of carb...

The basic building blocks of nano-structured hierarchical cellular materials are nano-sized wires or plates. Due to the effects of surface elasticity and the initial stress/strain, their bending, torsion, stretching and transverse shear rigidities are not only size-dependent, but also tunable and controllable over a large range. Based on the closed form results of the bending, torsion, stretchi...

Motivation It has been recognized by many within the energetic materials community that the use of nano-sized energetic particles can lead to substantial increases in overall performance and safety of energetic materials. Nano-sized energetic particles offer the potential of high heat release rates, increased combustion efficiencies, tailored burning rates, and reduced sensitivity. In order to ...
