An accidental discovery in a laboratory at Oregon State University has apparently solved a quest that over thousands of years has absorbed the energies of ancient Egyptians, the Han dynasty in China, Mayan cultures and more "“ the creation of a near-perfect blue pigment. Through much of recorded human history, people around the world have sought inorganic compounds that could be used to paint things blue, often with limited success. Most had environmental or durability issues. Cobalt...

IZMIR, Turkey, Sept. 29 /PRNewswire-FirstCall/ -- Gryphon Resources reported today it has begun negotiations for purchase of a significant oil & gas exploration interest in Turkey. CEO Serdar Kirmizioglu described this initiative "As a significant expansion of our strategic plans which effectively diversifies the Company. This is a good opportunity and we're confident we can successfully manage oil exploration and continued exploration for manganese and copper. Negotiations are...

That palm tree magnet commemorating your last vacation is programmed for a simple function "“ to stick to your refrigerator. Similarly, semiconductors are programmed to convey bits of information small and large, processing information on your computer or cell phone.Scientists are working to coax those semiconductors to be more than conveyers, to actually perform some functions like magnets, such as data recording and electronic control. So far most of those effects could only be...

Hypoxia, or lack of oxygen, in bottom waters is a well known environmental problem. New research at the University of Gothenburg, Sweden adds to the list of ill effects: hypoxia leads to increased levels of manganese, which damages the immune response in marine animals.Water eutrophication and the resulting hypoxia is an ever-current issue, not least in connection with summer algal blooms. A more recently acknowledged problem is that hypoxia, which occurs when algae is broken down, increases...

A U.S. researcher says manganese in the environment may correlate with both decreases and increases in cancer deaths. The study, published online by Biological Trace Element Research, says airborne manganese was associated at the county level with a 14 percent decrease in total cancer deaths. The study also finds a 43 percent decrease in breast cancer deaths and a 22 percent decrease in lung cancer deaths. However, there was up to a 28 percent increase in colon cancer deaths and a 26...

U.S. scientists say they have discovered marine microorganisms use manganese and iron to convert methane into carbon dioxide. The Pennsylvania State University researchers said their finding is important because carbon dioxide can produce compounds that sequester carbon in the ocean, reducing the amount of CO2 in the Earth's atmosphere. That process had previously been thought to be dependent on compounds containing sulfur. Graduate student Emily Beal, principal author of the study, said the...

In the first ecological study of its kind in the world, a Wake Forest University Baptist Medical Center researcher has uncovered the unique finding that groundwater and airborne manganese in North Carolina correlates with cancer mortality at the county level.The study, titled, "Environmental Manganese and Cancer Mortality Rates by County in North Carolina: An Ecological Study," was published online last month by Biological Trace Element Research. Lead researcher John Spangler, M.D., professor...

Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. These same compounds may have been key to methane reduction in the early, oxygenless days of the planet's atmosphere."We used to believe that microbes only consumed methane in marine anaerobic sediment if sulfate was present," said Emily Beal, graduate student...

For a long time, batteries were bulky and heavy. Now, a new cutting-edge battery is revolutionizing the field. It is thinner than a millimeter, lighter than a gram, and can be produced cost-effectively through a printing process.In the past, it was necessary to race to the bank for every money transfer and every bank statement. Today, bank transactions can be easily carried out at home. Now where is that piece of paper again with the TAN numbers? In the future you can spare yourself the...

A species of bacteria, isolated from sediments deep under the Pacific Ocean, could provide a powerful clean-up tool for heavy metal pollution. Writing in the current issue of the journal, Microbiology, Professor Gejiao Wang and his colleagues from Huazhong Agricultural University in Wuhan, PR China describe how a particular strain of Brachybacterium, strain Mn32, proved to be highly effective in removing manganese from solutions, converting it into insoluble manganese oxides. Not only did the...

Aluminum (or aluminium) is a soft, lightweight, silvery metal. It is an element in the boron group on the periodic table of elements, with the symbol Al and atomic number 13. On the earth's crust, aluminum is the most abundant metal, and the third most abundant of all elements on the earth's crust, after oxygen and silicon. It accounts for 8% of the weight of the Earth's solid surface. Because aluminum is a highly reactive metal, it doesn't occur in nature in a pure form. Aluminum forms a...

Manganese is a chemical element in the periodic table that has the symbol Mn and atomic number 25. Notable characteristics Manganese is a gray-white metal, resembling iron. It is a hard metal and is very brittle, fusible with difficulty, but easily oxidized. Manganese metal is ferromagnetic only after special treatment. The most common oxidation states of manganese are +2, +3, +4, +6 and +7, though oxidation states from +1 to +7 are observed. Mn2+ often competes with Mg2+ in...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
