This article focuses on one of the Earth's rare metal which falls under the lanthanide group in the periodic table. Praseodymium Greek meaning is a green twin. It is a metal that is malleable. When exposed with air, Praseodymium turns into praseodymium oxide. In all the processes that make Praseodymium oxide, calcination is done in all of them. The physical properties of prepared nanoparticles depend strongly on conditions of calcination. Pr6O11 has a cubic fluorite structure of a cr …

Graphene is the newborn superstar of materials sciences. Hence the characterization, classification, production, and utilization of graphene and graphene based products have been at the center of attention in the last few decades. The potential properties of this wonder material have been theorized and simulated in several different studies. However, achieving these properties has been a challenge due to the problems in achieving pristine graphene flakes. The production process of gr …

The nickel foil is fabricated by a process called continuous electrodeposition through which, a foil with a consistent quality is produced in greater dimensions and lower thicknesses compared to that prepared by conventional metal rolling. Vahid Javan KouzegaranAnalytical Chemist (Ph.D.) / Nanografi Nano TechnologyIntroductionTechnically, the nickel foil that is electroformed has favorable chemical purity, consistent and excellent surface finish as well as desirable etching characteris …

In the 21st century, when humans become aware of environmental conservation, applications of renewable resources become more and more important for their daily life since they are friendly to nature. Nanotechnology, in the recent years, has gotten huge interest in many industries and nanotechnology has opened up for many new possibilities, such as in the forest industry and cellulose-based products.Introduction Nanotechnology is defined as the understanding and control of matter with …

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 …
