Researchers Show Evidence Of Common Mineral Capable Of Making, Breaking Bonds
2014-07-30 03:37:00

Arizona State University ASU team shows evidence for one mineral affecting the most fundamental process in organic chemistry: Carbon-hydrogen bond breaking and making Reactions among minerals and organic compounds in hydrothermal environments are critical components of the Earth's deep carbon cycle, they provide energy for the deep biosphere, and may have implications for the origins of life. However, very little is known about how minerals influence organic reactions. A team of...

Alan McStravick for redOrbit.com - Your Universe Online A few years back, Kelly Clarkson, the first winner of television's biggest talent show, American Idol, reminded us of the adage “what doesn't kill you makes you stronger,” in her 2011 hit single 'Stronger'. The unfortunate failure in that logic is that sometimes what you come up against will actually kill you. Today, we learn about researchers from the University of Exeter Medical School who have studied a potentially lethal...

Did Life Originate At Deep Sea Vents?
2014-04-10 10:34:45

Woods Hole Oceanographic Institution One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about exactly how life began. One possibility has grown in popularity in the last two decades - that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world. Recent research by...

New Semiconductor Has Promise For 2D Physics And Electronics
2014-03-21 16:13:43

Lynn Yarris, Berkeley Lab From super-lubricants, to solar cells, to the fledgling technology of valleytronics, there is much to be excited about with the discovery of a unique new two-dimensional semiconductor, rhenium disulfide, by researchers at Berkeley Lab’s Molecular Foundry. Rhenium disulfide, unlike molybdenum disulfide and other dichalcogenides, behaves electronically as if it were a 2D monolayer even as a 3D bulk material. This not only opens the door to 2D electronic...

Researchers from Denmark and Stanford show how to produce industrial quantities of hydrogen without emitting carbon into the atmosphere University researchers from two continents have engineered an efficient and environmentally friendly catalyst for the production of molecular hydrogen (H2), a compound used extensively in modern industry to manufacture fertilizer and refine crude oil into gasoline. Although hydrogen is abundant element, it is generally not found as the pure gas H2but is...

Versatility of new technique shows promise as new benchmark in exfoliation chemistry of two-dimensional chalcogenides A team of scientists from the National University of Singapore (NUS) has successfully developed a method to chemically exfoliate molybdenum disulfide crystals, a class of chalcogenide compounds, into high quality monolayer flakes, with higher yield and larger flake size than current methods. The exfoliated flakes can be made into a printable solution, which can be applied...

Toxic Ocean Conditions During Ancient Extinction Event Analyzed
2013-10-30 04:24:55

redOrbit Staff & Wire Reports - Your Universe Online Toxic oxygen-free and hydrogen sulfide-rich ocean conditions that existed during a major extinction event nearly 94 million years ago could repeat themselves in the future, according to new research being published online this week in the journal Proceedings of the National Academy of Sciences. Research, led by biogeochemists at the University of California, Riverside, suggests that the previous estimates of these oxygen-free,...

Galena is a lead ore. This article describes Galena's mineral properties. In its chemically purified form, Galena is known as Lead Sulfide; refer to that article for chemical and industrial uses. Galena is one of the most abundant and widely distributed sulfide minerals, and is the most common ore of lead. Crystals are usually cubic, sometimes octahedral. It is often associated with the minerals sphalerite and fluorite. Galena deposits sometimes contain significant amounts of silver as an...

Pentlandite is a iron-nickel sulfide, (Fe,Ni)9S8. Pentlandite usually has a Ni:Fe ratio of close to 1:1. It also contains minor cobalt. Pentlandite forms isometric crystals, but is normally found in massive granular aggregates. It is brittle with a hardness of 3.5 - 4 and specific gravity of 4.6 - 5.0 and is non-magnetic. It has a yellowish bronze color. Pentlandite is the chief ore of nickel. Typically associated with pyrrhotite, niccolite, biotite, millerite, pyrite, and chalcopyrite...

Silver is a chemical element in the periodic table that has the symbol Ag (from the traditional abbreviation from the Latin Argentum) and atomic number 47. A soft white lustrous transition metal, silver has the highest electrical and thermal conductivity of any metal and occurs in minerals and in free form. This metal is used in coins, jewelry, tableware, and photography. Notable characteristics Silver is a very ductile and malleable (slightly harder than gold) univalent coinage metal...

Tennantite is a copper arsenic sulfide mineral. Its chemical formula is Cu12As4S13. It is found in hydrothermal veins and contact metamorphic deposits. A closely related mineral, tetrahedrite (Cu12Sb4S13) has antimony substituting for arsenic and the two form a solid solution series. The two have very similiar properties and is often difficult to distinguish between tennantite and tetrahedrite. Iron, zinc, and silver substitute up to about 15% for the copper site. The mineral was named...
