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 …

One of the most innovative advances of the twentieth century was the discovery of the transistor which completely revolutionized the electronics sector. After 60 years, its appearance has not abandoned its privilege, it is considered the most important active device in electronics.Transistors have transformed the planet with great technological advances based on modern electronics with great integration power and processing speed, from which information and communications are nurtured. Th …

Graphene nanoplatelets with a typical density of about 8 nanometers are available in different sizes up to an estimated 51 microns. Such fascinating nano-particles are made up of small sheets of platelet-shaped graphene, similar to the one present in carbon nano-tubes walls, though in a planar shape. It is possible to add hydrogen and covalent bonding powered by functionalization on platelet edges. Because of their unusual size and structure, the graphene nanoplatelets can attain impr …

Being investigated in scientific research and practical applications as one of the most important members of carbon fibers is Carbon Nanofiber (CNF). They are considered as promising materials in different disciplines like electrical and electronics devices, electrode material for batteries, supercapacitors and as the sensor. They are usually useful in application in which high electrical conductivity is required, which depends on the dispersion and percolation status in the matrix materi …
