Geochemistry

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 completely more

Like iron flowing through the blood stream, iron minerals course through the ground. These minerals are used to make steel and other metal alloys used in everything from cell phone components and cars to buildings, industrial equipment and infrastructure. Unfortunately, when exposed to oxygen and mo more

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 stu more

Gérard Hopfgartner, studied chemistry at the University of Geneva and received his Ph.D. degree in 1991 in the field of organic geochemistry and mass spectrometry. He pursued his formation as a postdoctoral fellow at Cornell University in the domain of LC-MS/MS atmospheric pressure ionization. Then more
