The unique electrical and thermal properties of graphene can enhance cutting-edge technologies and our daily lives day by day. Graphene is a carbon sheet having nano-sized thickness with unique properties. It has a monolayer hexagonal crystalline structure and is really the basis of graphite. Yet it is 200 times stronger than steel and five times lighter than aluminum. The unique electrical and thermal properties of graphene make it attractive for many uses of graphene in our daily l …

There are two different ways by which metallic nanoparticles can be formed. These are the bottom-up approach and the top-down approach. The two can be distinguished in the sense that while the bottom up method is sourced from scientific research including nanoscience, the top-down is not. The bottom-up approach further comprises of creating nanomaterials and objects within the same nanosphere based on atoms, molecules, and aggregate grouping. IntroductionThis sort of groupin …

The Rare Earth elements are very special and are used in most modern technologies. The Rare Earth elements include as many as 17 chemical elements, which in recent years have become very precious and refined. In many productions (magnets, catalysts, displays) the Rare Earth elements are indispensable. The Rare Earth elements are these: dysprosium (Dy), cerium (Ce), erbium (Er), gadolinium (Gd), europium (Eu), holmium (Ho), Lutetium (Lu), lanthanum (La) …

Sputtering is a physical process in which atoms in a solid-state (target) are released and pass into the gas phase by bombardment with energetic ions (mainly noble gas ions). IntroductionSputtering is usually understood as the sputter deposition, a high vacuum-based coating technique belonging to the group of PVD processes. Furthermore, sputtering in surface physics is used as a cleaning method for the preparation of high-purity surfaces and as a method for analyzing the chemical …

Solar sails to travel between the stars. Space elevators to take satellites and astronauts into orbit without using an ounce of fuel. Lighter aircraft, helicopters, sturdy and invisible to radar. These are just some of the incredible applications of graphene, the wonder material made from a single layer of carbon atoms, in the aerospace sector. Graphene is revolutionizing not only Earth but also Space. The heat dissipation capacity of graphene allows producing ever smaller and more compet …
