Boron carbide (B4C) is often named as “Black diamond”. It is a black crystalline solid almost as hard as diamond. The compound contains 1 Carbon atom and 4 Boron atoms. It is grayish black in color and usually a very hard ceramic material. It is to be noted that Carbon and Boron are placed adjacent to each other in the periodic table, having atomic numbers like 6 and 5, respectively. The  boron carbide nanoparticles  are of approximately 40 nm in diameter . It is used across a number of industries due to its hardness, unique interaction with neutrons, and basic properties. Boron carbide nanoparticles have experienced extensive research from engineers and researchers. The  mechanical properties of  Boron Carbide make it useful in various applications.  This article is focused on Boron Carbide Nanoparticles, its history, properties, manufacturing and applications in different sectors . History of Boron Carbide Nanoparticles B4C was discovered in the 19 th...

The  nanopowder of Carbon Black  is conductive and non-polluting. The applications of Carbon Black Nanopowder are versatile, the sectors involved are plastics, electronics, inks, coatings, and green technology.  Carbon Black is predominantly used as reinforcing filler and in the rubber industry.  Approximately, thirty grades of it are produced for this purpose so they impart a wide spectrum of properties to rubber products. History of Carbon Black Nanopowder Carbon Black is produced by different activities such as the  incomplete combustion of fossil fuels , including diesel and fuel oil, as well as the burning of firewood, among others. Carbon black was initially produced in China by incomplete combustion in oil lamps and intended to provide the black pigment of the Indian ink. In 1912, it showed exceptional qualities for rubber tire reinforcement. Production Capacity of Carbon Black Nanopowder In 2017, the global production capacity was 16 million t...

Gallium arsenide (GaAs)  is a compound of gallium and arsenic. It is a vital semiconductor and is commonly used to manufacture devices such as infrared emitting diodes, laser diodes, integrated circuits at microwave frequencies, and photovoltaic cells. Structure of Gallium arsenide (GaAs) Wafer In the  Gallium arsenide (GaAs) Wafer , each gallium atom is bordered by arsenic atoms. 5 valence electrons of arsenic atoms and 3 valence electrons of gallium atoms share each other. So, each of the gallium and arsenic atom gets 8 valence electrons in the outer shell. It is also to be noted that a covalent bond exists between gallium and arsenic atom in the GaAs Wafer. The covalent bonds despite being strong can be broken with an enough amount of external energy. Properties of GaAs Wafer The main properties of gallium arsenide (GaAs) are given below: The Molar mass of Gallium arsenide (GaAs) is 144.64 g/mol. Gallium arsenide (GaAs) has the Melting point of 1238 °C. The...

A hydraulic crimping machine  can be straightforwardly explained as a machine that is designed and used by manufacturers across the world in order to crimp or secure together with a connector to the border most point of a hose. This can be better understood as the attachment of distortable metallic fixtures with segments of both inflexible and pliable hose and tubing. This is done by joining the two ends of a cable (also referred to as the hose) by either crimping one portion or both ends of it. The advancements in technology that have removed the trouble of individuals having the need to handle these tools have brought about a significant advantage to the modern world. Many of the modern tools that have been designed are extremely light in weight and compact (e.g. hand hydraulic crimper tool). This further eases the task of handling and using it. These machines can also be completely independent and self-contained. Moreover, quicker crimp cycles and more streamlined shaping m...

Nano-cellulose is a material that consists of  cellulose nano-fibers , which are a string of cellulose molecules with an elongated tubular shape. Nano-cellulose in the future will be cheap, resistant, organic and ecological. It is paradoxical that the future solutions for the world that will serve as the basis for the technological infrastructures and will govern the life of future generations are not visible to the human eye. Scientists from the University of Texas use the same bacteria that produces coconut cream to transform algae into nano-cellulose; an element that could revolutionize the world. Nano-cellulose is a plant material that is broken down into microscopic pieces, then purified and rebuilt. The bacterium Acetobacter xylinum is able to synthesize the cellulose found in blue-green algae, with only a little water, sunlight and time. The process absorbs carbon dioxide, the greenhouse gas mainly responsible for global warming. Properties of Nanocellulose It is li...
