The wheels are generally made from a composite material consisting of coarse-particle aggregate pressed and bonded together by a cementing matrix (called the bond in grinding wheel terminology) to form a solid, circular shape. Various profiles and cross sections are available depending on the intended usage for the wheel. They may also be made from a solid steel or aluminium disc with particles bonded to the surface. Today most grinding wheels are artificial composites made with artificial aggregates, but the history of grinding wheels began with natural composite stones, such as those used for millstones.
A glass wafer is a thin piece of semiconductor material, usually borosilicate glass, quartz or fused silica, in the shape of a very thin disc that is used as a base for fabricating electronic integrated circuits (ICs) and silicon-based photovoltaic cells. The glass wafer serves as the substrate for most microelectronic circuits and goes through many processes, such as doping, implantation and etching, before the final product of an integrated circuit is completed.
An amorphous metal (also known as metallic glass or glassy metal) is a solid metallic material, usually an alloy, with a disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms. Amorphous metals are non-crystalline, and have a glass-like structure. But unlike common glasses, such as window glass, which are typically electrical insulators, amorphous metals have good electrical conductivity. There are several ways in which amorphous metals can be produced, including extremely rapid cooling, physical vapor deposition, solid-state reaction, ion irradiation, and mechanical alloying.
The Amorphous Fluoropolymer is formed by the reaction of Tetrafluoroethylene (TFE) and Perfluoro (2,2-dimethyl) -1,3 Dioxolane (PDD). It is completely non-crystalline transparent amorphous polymer, no obvious melting point, has good optical and electrical properties, but also has excellent resistance to chemical, heat resistance, good mechanical properties and physical properties.
Surfactants are chemical products consumed in large quantities every day on a worldwide scale. The development of less irritant, less toxic, consumer-friendly surfactants is, therefore, of general interest. Amino-acid-based surfactants constitute a novel class of surfactants produced from renewable raw materials and can be seen as an alternative to conventional surfactants.
"Algae products are simple plants that can range from the microscopic (microalgae), to large seaweeds (macroalgae), such as giant kelp more than one hundred feet in length. 

Algae products can be grown using water resources such as brackish-, sea-, and wastewater unsuitable for cultivating agricultural crops. When using wastewater, such as municipal, animal and even some industrial runoff, they can help in its treatment and purification, while benefiting from using the nutrients present."
The unrelenting passion of the aerospace and defense industry to enhance the performance of commercial and military aircraft is constantly driving the development of improved high performance structural materials. Composite materials are one such class of materials that play a signifcant role in current and future aerospace components. Composite materials are particularly attractive to aviation and aerospace applications because of their exceptional strength and stiffness-to-density ratios and superior physical properties. Aerospace & defense composite ducting is composite with glass fiber, carbon fiber, epoxy resin, phenolic resin, thermoplastic resin, etc.
Wiper Blade is a device used to keep the window clean, moving back and forth across the windshield countless times as they sweep the water away. A Wiper Blade mainly consists of a pivot socket, two end ferrules, a spring steel sheet and a rubber strip. The spring sheet steel in Wiper Blade dispersive pressure to the whole and make all parts of the Wiper Blade bear averaged force, removing the rain mark and scratch on the windscreen. The Wiper Blade can last longer, coupled with uniform force, anti-sun, simple structure and lighter weight features.
