Graphene is a material obtained by exfoliation of graphite. It consists of carbon atoms arranged in a hexagonal pattern and forms sheets as thin as atoms. Graphene has, among other characteristics, to be an extremely effective water filter. A graphene water filter is very effective. The graphene water filter is considerably more efficient than water filters on the market since the quantity of pure water that this new type of filter can produce is 8 to 9 times greater than that of com …

Antimony doped tin oxide (ATO) nanoparticles have been proven to exhibit special optical property and excellent electrical conductivity to be used as thin film electrodes. Studies have shown that antimony doped tin oxide possesses a high n-type electric performance and employed in the form of the traditionally produced aerogel thin films for the purpose of collecting electrons in solar cells.Vahid Javan KouzegaranAnalytical Chemist (Ph.D.) / Nanografi Nano TechnologyIntroduction Introd …

From the stone ages to modern history, new materials have often been the enablers of revolutionary technologies. For a wide variety of envisioned applications in space exploration, energy-efficient aircraft, and armor, materials must be significantly stronger, stiffer, and lighter than what is currently available. Carbon nanotubes (CNTs) have extremely high strength, very high stiffness, low density, good chemical stability, and high thermal and electrical conductivities. These superior pro …

Cadmium sulfide nanoparticles and their quantum dot version are of a significant interest due to their semiconducting and luminescent properties, especially their controllable emission bands, continuous excitation and the ease of functionalization. Cadmium sulfide (CDS) is particularly used in devices with optoelectronic property and is known to be a direct band gap material at room temperature. Cadmium sulfide has attracted a lot of attention due to an extensive range of applications …

Nanotechnology is the new star player in solar energy technologies. Nanostructures offer remedies to the present drawbacks of conventional solar cells including high material costs and efficiency limits. Nanostructures and nanomaterials are utilized for the improvement of thin film solar cell and dye-sensitized solar cells as well as the development of organic and carbon based solar cells, ETA, and QD solar cells.IntroductionThe most emphasized problem of modern life in the 21. century is …
