1 Introduction Carbon nanotubes (CNTs) were observed by Iijima 1 in 1991, after the discovery of fullerenes in the mid‐1980s by Smalley and co‐workers. 2 The first reported method for their synthesis was the carbon arc discharge. 1 Since then, an extensive research on CNTs has been stimulated by their outstanding chemical and physical properties, 3-5 and many other approaches have been

Steel is an alloy of iron and carbon and, sometimes, other elements like chromium. Because of its high tensile strength and low cost, it is a major component used in buildings, infrastructure, tools, ships, trains, automobiles, machines, appliances, and weapons.
The aim of this symposium is to provide a forum to discuss current trends and cutting-edge research on the engineering of functional materials and devices based on tailored chemical coating methods, both in 2D (thin films) and in 3D (nanostructures
Typical boriding mixture consists of boron carbide powder diluted with other refractory materials such as alumina or silicon carbide. Potassium tetrafluoroborate (KBF4) is used as a flux. The process converts some of the Fe to iron boride, consisting of two phases: FeB concentrated near the surface, and diiron boride (Fe2B).

7/9/1999· When the silicon-treated carbon black is examined under STEM-EDX, the silicon signal corresponding to the silicon-containing species is found to be present in individual carbon black aggregates. By comparison, for example, in a physical mixture of silica and carbon black, STEM-EDX examination reveals distinctly separate silica and carbon black aggregates.
Handbook of Preparative Inorganic Chemistry, Volume 1, Second Edition focuses on the methods and mechanisms involved in conducting experiments on inorganic chemistry. Composed of contributions of various authors, the first part of the handbook
The introduction of electromobility causes major challenges as new components and materials enter vehicle recycling. This paper discusses the current developments in the recycling of traction batteries, electric motors, and power electronics, which constitute the key components of (hybrid) electric vehicles. Both technical and ecological aspects are addressed. Beside base metals, all
Silicon-based substances (silicon rubber, silicon oil, silicon-based coating material, silicon caulking compound, etc.) emit volatile silicon gas. Note that when silicon is used near relay, switching the contacts in the presence of its gas causes silicon to adhere to the contacts and may result in contact failure (in plastic seal types, too).

Silicon carbide (SiC) is a synthetic mineral most commonly produced in electrical resistance furnaces by the Acheson process. A mixture of carbon material (usually petroleum coke) and either silica or quartz sand is reacted at high temperatures (1,700 – 2,500
Carbon dioxide was the first gas to be described as a discrete substance. In about 1640, the Flemish chemist Jan Baptist van Helmont observed that when he burned charcoal in a closed vessel, the mass of the resulting ash was much less than that of the original …
Silicon Carbide (SiC) is the chemical compound of carbon and silicon. Recognized as a perfect semiconductor with superior characteristics, SiC is widely used in high-temperature, high-power, and high-frequency electronic appliions.
