Ferrofluid is a liquid that is attracted to the poles of a magnet.It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1]
Cumberlandite is a specific type of plutonic rock called a melanocratic troctolite, or melatroctolite. [1] It is the state rock of Rhode Island and can be found in a 4-acre (0.016 km 2) lot in Cumberland, Rhode Island at Iron Mine Hill. [2] [3] Further traces can be found scattered throughout the Narragansett Bay watershed as far as Martha's ...
Sachiko Kodama (born 1970) is a Japanese artist. She is best known for her artwork using ferrofluid, a dark colloidal suspension of magnetic nano-particles dispersed in solution which remains strongly magnetic in its fluid. [1]
The use of rock has had a huge impact on the cultural and technological development of the human race. Rock has been used by humans and other hominids for at least 2.5 million years. [22] Lithic technology marks some of the oldest and continuously used technologies. The mining of rock for its metal content has been one of the most important ...
The average cloud weighs over one million pounds. Wearing a necktie could reduce blood flow to your brain by up to 7.5 percent. Animals can also be allergic to humans.
Ironstone (sandstone with iron oxides) from the Mississippian Breathitt Formation, Mile Marker 166, I-64, Kentucky. Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially.
Actinolite is commonly found in metamorphic rocks, such as contact aureoles surrounding cooled intrusive igneous rocks. It also occurs as a product of metamorphism of magnesium-rich limestones. The old mineral name uralite is at times applied to an alteration product of primary pyroxene by a mixture composed largely of actinolite.
The majority of rock exposures on the Island may be found along the coastlines, with inland exposures scarce and usually highly weathered. There is a broad geological division between the north and south of the Island. The Southern Metamorphic Complex is elevated above the geologically younger, lower lying Northern Igneous Complex. Guernsey has ...
