Alternative Synthetic Pathways for Metal Oxide Nanomaterials Goodbye to organics: Toxic and volatile solvents are avoided
Nanoscience is regarded and acknowledged as triumph of human ingenuity. The requirements of simple and reliable protocols for the preparation of nanomaterials with controlled morphology continue to be a major challenge in nanosciences. Carbon nanotubes (CNTs) were not the only materials to raise red flags. Nanostructures including particles, rods, wires, belts, cages, walls, flowers and rings have been reported to be harmful. Their unique physical characteristics raise concerns that tiny clamps of metals, ceramics and organics could prove uniquely toxic as well. Nanomaterials made from the urea, polyethylene glycol, polyvinylpyrrolidone, polytertrafluoethylene or PTFE, showed even more dramatic effects. Toxicologist, Gunter reported that when his lab exposed rats to air containing nanoparticles for 15 minutes, most of the animals died within 4 hours. Gunter in his report suggested that the technique for making smaller particles could have altered them chemically.
Chemical synthesis of nanomaterials has been reviewed by many authors and improvements and better methods have been reported continually in the last few years. An overview of those methods [see reference 1], however, shows that they involve multistep process and frequent use of amines and other structure directing reagents. Hence, the synthesis is usually tedious and requires careful removal of catalysts and reagents. In addition, the path ways suggested involve environmentally harmful chemicals which are toxic and not easily degraded in the environment. Organic solvents are also problematic because many are harmful to health and environment. Other techniques (physical) are technically complex, requires high temperature, harsh growth conditions, expensive experimental set up and complicated control process. A simple approach that can avoid organics or amines for large scale production and controlled growth of versatile nanomaterials is, therefore, highly desired.
In response to the above concerns, Shah Ashraf have discovered and explored a new bio-safe and bio-compatible route for the synthesis of oxide nanomaterials. The route is based on simple reaction of water and metal powder at relatively low temperature. Since water is regarded as a benign solvent and non toxic, the product (nanostructures) could be used safely for biomedical and other applications. In addition, the method is simple, fast, economical, involves green chemistry, which can make it suitable for scale large production. The prospects of the process are bright and promising. The approach described above is expected to show marvelous results.

hi my dear sir ,

am students of nano technology ,and very very intresting in nanotechnology ,

want to contributes some things to this field of tecnology ,

so therfore i started a projects on "THIN FLIMN DEPOSTION "

 i need som usefull latrature and research papers on thin film deposition ,

i hope  you wil help me .and you will incourage me also .

best and kind regards .

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu

Dr. András Paszternák, founder of Nanopaprika
