The extraction of renewable energy resources particularly from earth abundant materials has always been a matter of significance in industrial products. Herein, we report a novel simultaneous extraction of nano-silicon with activated carbons (nano-Si@ACs) from rice husk (RH) by chemical activation method. As-extracted nano-Si@ACs is then used as an energy harvesting materials in counter electro...

The conversion of waste to wealth has recently grossed high attention as it possesses the ability boost economy any nation; hence, this research. In study, characterization and investigation mechanical properties nano- flux (CaO) welding powder developed from bio-agrowaste (eggshell) was carried out. Mild, galvanized stainless steel plates rods were used parent metals for experiment. Results ob...

C is the second most important natural polymer in the nature after cellulose. The main sources of the chitin compounds are shrimp and crabs.Our objective is to discuss the state of the art on extraction of nano chitin whiskers and Chitin based nanocomposites using different type of polymer matrixes. This review manly focuses on the preparation, characterization, properties, morphologies and che...

nano-sized titanium dioxide tio2 powder was successfully prepared from its precursor titanium (iv) chloride by a simple and new wet chemical method. ticl4 were used as precursor in hydrogen peroxide, h2o2 and ethanol. this solution was then peptized using nitric acid and heated under reflux at 80°c. their physico-chemical properties were then characterized by transmission electron microscopy (t...

In this study, mechanochemcical process(MCP) is applied to synthesize ultrafine TaC powders. In this research, nano powder composite TaC-TaB2 was produced using mixtures of tantalum carbide and boron carbide as raw materials via mechanochemical process. The phase formation characterization during process was utilized by X-ray diffractometry (XRD). The morphology of synthesized powder was studie...

according to recent achievements in nano technology we can see its effects in different engineering fields. in nano manufacture process the first essential step is modeling coordinately in order to make it available different software are developing for this propose.  in this paper nano modeling for two papers is developed first understanding structure in nano and micro size and second simulati...

Microorganisms release a diversity of organic compounds that couple interspecies metabolism, enable communication, or provide benefits to other microbes. Increased knowledge of microbial metabolite production will contribute to understanding of the dynamic microbial world and can potentially lead to new developments in drug discovery, biofuel production, and clinical research. Nanospray desorpt...

This paper presents the preparation and characterization of a porous antimicrobial composite material consisting diatomaceous earth, an inorganic pore-forming agent, nano-zinc oxide (ZnO). A modified direct precipitation device produced high-surface area ZnO powder. The effect reaction temperature, volume flow rate, titration rate on particle size was studied. Using sodium chloride, potassium n...
