TiO2-doped SnO2 nanopowder is synthesized via a sol-gel method and characterized by atomic force microscopy and X-ray diffraction. Using this nanopowder, we have fabricated a novel semiconductor gas sensor that is sensitive to UV light illumination. We find that gas-sensing properties of TiO2-doped SnO2 sensor can be enhanced significantly under the exposure of UV light. The sensor exhibits a h...

objective: osseous defects around dental implants are often seen when implants are placed in areas with inadequate alveolar bone, or around failing implants. bone regeneration in these areas using bone grafts or its substitutes may improve dental implants prognosis. the aim of this study was to prepare and characterize the bioactive glass nanopowder and development of its coating for treatment ...

In this paper, we report the preparation and characterization of both the ZnO nanocrystalline thin films and nanopowder by ultrasonic spray pyrolysis technique. ZnO films were grown on polished Si(1 0 0) and amorphous glass substrates at different deposition temperature range varying from 200 to 500 1C. Both orientation and the size of the crystallites were found to depend on the substrate and ...

The identification of similarities in the material requirements for applications of interest and those of living organisms provides opportunities to use renewable natural resources to develop better materials and design better devices. In our work, we harness this strategy to build high-capacity silicon (Si) nanopowder-based lithium (Li)-ion batteries with improved performance characteristics. ...

Nanoparticles (NPs) are applied in a wide range of processes, and their use continues to increase. Fluidization is one of the best techniques available to disperse and process NPs. NPs cannot be fluidized individually; they fluidize as very porous agglomerates. The objective of this article is to review the developments in nanopowder fluidization. Often, it is needed to apply an assistance meth...

Synthesis of TiO2 nanopowder via a low cost ultrasonic spray pyrolysis technique is reported and the nanopowder is used for the surface modification of glassy carbon electrode. The structural characterization of nanopowder by high temperature XRD clearly shows the phase transformation from anatase to rutile phase on increasing temperature. The morphological structure is characterized by field e...

Nanosized Powders are known to have very useful applications in the areas of medical, structural, chemical and other various fields because of their enhanced physical, optical, and magnetic properties. Several Synthesis methods have been developed for the production of nanopowders. This paper will discuss different methods used for the production of nanosized powders and their advantages and di...

The nanoparticle technologies consisting of multiple layers of mixtures of activated carbon and ruthenium (IV) oxide for super capacitors are reported. The mono-particulate layer process described here is a modified Langmuir-Blodgett trough. We report the processes for a spray-coated zinc nanopowder electrode used as a counter-electrode forming a galvanic cell of extremely high charge storage c...
