The importance of batteries is undeniable, whereas the most important part of batteries is the cathode. The reason for that is very simple and obvious. The main factor that defines the battery is the voltage level. The elements that maintain and are responsible for the regulation of voltage include the quality of electrolyte as well, but the cathode is mainly responsible for the regulation and maintenance of the voltage, decide the level and quality as well. In this article is discussed th …

Fullerenes are the allotropic form of carbon and a closed convex polyhedra, composed of an even number of carbon atoms. The name fullerene originated from that of Richard Buckminster Fuller (1895-1983), an American engineer, architect, inventor, and writer, known for having discovered the structural principle of tensegrity, it is the property of a structure that stand by the forces of tension and compression. Fuller is also known for his works on the synergetic, his participation in the G …

This article mainly discusses two of the methods used for the preparation of the nanoparticles and nanocomposite particles. Apart from the nanoparticles and nanocomposite particles, these methods can be utilized in the production of different metallic, metallic oxides, metallic alloys nanomaterials, carbon nanomaterials, etc. Both methods use bottom-up approach out of the two approaches (top-down, bottom-up) for the preparation of the nanoparticles and nanocomposite particles. Inert G …

At present, lithium batteries are the most widespread types of energy accumulator in the world and are used in a huge diversity of implementations, including smartphones, notebooks, tablets, and many other devices that require a reliable battery and with a large performance. That is why lithium batteries are the most chosen accumulator among manufacturers and developers worldwide, precisely because of their energy efficiency, without a doubt, it is the most important variable when it come …
