New Measurement Device: Carbon Dioxide As Geothermometer

Researchers quantify rare CO2 variants using laser spectroscopy

22-May-2019 - For the first time it is possible to measure, simultaneously and with extreme precision, four rare molecular variants of carbon dioxide (CO2) using a novel laser instrument. It is thus able to measure the temperature during the formation of CO2-binding carbonates and carbonaceous fossils ...

Widespread uranium contamination found in India's groundwater

11-Jun-2018 - A new Duke University-led study has found widespread uranium contamination in groundwater from aquifers in 16 Indian states. The main source of the uranium contamination is natural, but human factors such as groundwater-table decline and nitrate pollution may be exacerbating the problem. Several ...

New insights about our Earth’s lower mantle

Scientists X-ray the most abundant mineral of Earth

21-Jul-2016 - Using DESY's bright X-ray light source PETRA III, a team of scientists has discovered unexpected facts about the most abundant mineral on Earth. The mineral bridgmanite makes up roughly one third of Earth’s entire volume and is the major component of Earth’s lower mantle. Thus, its physical ...

Scientists and NASA astronauts developing near real-time osteoporosis and bone cancer test

19-Aug-2015 - A new test for offers the possibility of near real time monitoring of bone diseases, such as osteoporosis and multiple myeloma. The functionality of the test, which measures changes in calcium isotope ratios, has been validated on blood samples from NASA space shuttle astronauts. Geochemists have ...

NMR under pressure: Reproducing deep-Earth chemistry

16-Jul-2014 - A new pressure cell invented by UC Davis researchers makes it possible to simulate chemical reactions deep in the Earth's crust. The cell allows researchers to perform nuclear magnetic resonance (NMR) measurements on as little as 10 microliters of liquid at pressures up to 20 kiloBar. "NMR is our ...

Sophisticated monitoring array to address mystery of uranium plume

Groundwater contamination remains significantly unchanged for 10 years

19-Sep-2008 - Scientists have puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium persists. Now, an innovative system has been installed ...

New Research Suggests Biofuel Blending is Often Inaccurate

Study of Retail Biofuel Samples Suggests National Standards May Be Needed

29-Feb-2008 - While sampling blended biodiesel fuels purchased from small-scale retailers, researchers at the Woods Hole Oceanographic Institution found that many of the blends do not contain the advertised amount of biofuel. Marine chemist Chris Reddy and colleagues sampled pure biodiesel and blends from ...
