Glycol ethers are a group of solvents based on alkyl ethers of ethylene glycol or propylene glycol commonly used in paints and cleaners. These solvents typically have a higher boiling point, together with the favorable solvent properties of lower-molecular-weight ethers and alcohols. The word "Cellosolve" was registered in 1924 as a United States trademark by Carbide & Carbon Chemicals Corp.
Read moreAsteroid mining is the exploitation of raw materials from asteroids and other minor planets, including near-Earth objects.Minerals can be mined from an asteroid or spent comet then used in space for construction materials or taken back to Earth. These include. Gold Iridium Silver, osmium, Palladium, Platinum, Rhenium, Rhodium, Ruthenium, and Tungsten for transport back to Earth; Iron, Cobalt, Manganese, Molybdenum,…
Read moreSpace manufacturing is the production of manufactured goods in an environment outside a planetary atmosphere. Typically this includes conditions of microgravity and hard vacuum. Manufacturing in space has several potential advantages over the Earth-based industry.
Read moreTerraforming of Mars is a process of planetary engineering by which the surface and climate of Mars would be deliberately changed to make large areas of the environment hospitable to humans, thus making the colonization of Mars safer and sustainable.

Read moreSpace colonization (also called space settlement, or extraterrestrial colonization) is the permanent human habitation of the planet Earth.Many arguments have been made for and against space colonization. The two most common in favor of colonization is survival of human civilization and the biosphere in the event of a planetary-scale disaster (natural or man-made), and the availability of additional resources in space that could enable expansion of human society.
Read moreSoot Remover is a Dry Powder compound formulated for safe removal of soot creosote fire scale and deposits from boilers and diesel engine exhaust systems to control corrosion on metal surface and increases boiler efficiency. It improves the condition of combustion gas passes in boilers burning heavy fuel oil or coal. It is used to remove unburned carbon slag deposits from Boiler furnances, superheaters, economizer, air heaters and exhaust path/ stacks. Soot remover is avaialable in powder…
Read moreCorrosion in space is the corrosion of materials occurring in outer space. Instead of moisture and oxygen acting as the primary corrosion causes, the materials exposed to outer space are subjected to vacuum, bombardment by ultraviolet and X-rays, and high-energy charged particles (mostly electrons and protons from solar wind). In the upper layers of the atmosphere (between 90–800 km), the atmospheric atoms, ions, and free radicals, most notably atomic oxygen, play a major role.
Read moreCorrosion is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usual metals) by chemical and/or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and stopping corrosion.
Read moreRust is an iron oxide, a usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances Rust consists of hydrated iron(III) oxides Fe2O3·nH2O and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3).
