Evolution Remained Stuck In Slime For A Billion Years
2014-02-19 15:18:39

Science in Public Tasmanian researchers have revealed ancient conditions that almost ended life on Earth, using a new technique they developed to hunt for mineral deposits. The first life developed in the ancient oceans around 3.6 billion years ago, but then nothing much happened. Life remained as little more than a layer of slime for a billion years. Suddenly, 550 million years ago, evolution burst back into action – and here we are today. So what was the hold-up during those 'boring...

Fool's gold may prove an unlikely alternative to overexploited catalytic materials Catalytic materials, which lower the energy barriers for chemical reactions, are used in everything from the commercial production of chemicals to catalytic converters in car engines. However, with current catalytic materials becoming increasingly expensive, scientists are exploring viable alternatives. Researchers at the University of Cambridge have now discovered that the sulphide material iron pyrite,...

Researchers Turning Fool's Gold Into Solar Energy Success
2011-11-29 05:38:12

Oregon State University researchers have found that "fool's gold" may offer a new, cheap and promising option for solar energy. Fool's gold, or pyrite, could be processed from some of the most abundant elements on Earth. “We´ve known for a long time that pyrite was interesting for its solar properties, but that it didn´t actually work,” Douglas Keszler, a distinguished professor of chemistry at OSU, said in a press release. “We didn´t really know why,...

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...

Sulfur (or Sulphur; see spelling below) is the chemical element in the periodic table that has the symbol S and atomic number 16. It is an abundant, tasteless, odorless, multivalent non-metal. Sulfur, in its native form, is a yellow crystaline solid. In nature, it can be found as the pure element or as sulfide and sulfate minerals. It is an essential element for life and is found in several amino acids. Its commercial uses are primarily in fertilizers but it is also widely used in gunpowder,...
