American researchers at the 2015 national meeting of American Chemical Society outlined the details of an unexpected source of precious metals - sewage. That’s right. According to new research, organic materials (biosolids) generated by wastewater treatment plants may be an untapped source of precious metals and rare elements, including gold, silver, platinum, copper, palladium and vanadium that are used to make cell phones, computers, and other electronic devices.
The ability of steel buildings to bend without fracturing, or ductility, allows for extreme lateral loading from earthquakes and wind. This loading, however, subjects the solid web and flanges of steel members to buckling and fracture, thus crumbling the flat, solid surface, and leading to the potential for great damage. Virginia Tech assistant professor Matthew Eatherton will be using a five-year, $500,000 National Science Foundation CAREER Award to research how steel plates with strategically removed geometric patterns may better withstand everyday loads and extreme events than the currently used standard steel plates.
Two previously unnoticed oceanic gateways of warm water have been linked to the extreme thinning of East Antarctica’s Totten Glacier according to new research from the University of Texas at Austin. This discovery raises concern for the state of the Antarctic ice sheet and rising sea levels.
Russian scientist, Andrew Kolmogorov’s theory of turbulence has been widely accepted as a basic tenet of fluid dynamic theory since its introduction in 1941. New research out of the University of California Santa Barbara (UCSB) is causing physicists to rethink turbulence.
Chances of a large magnitude earthquake in California are higher than previously estimated seven years ago. Scientists came up with the new prediction using a new model based on the latest research and seismological data.
A collaboration between researchers at the University of West England Bristol (UWE Bristol) and Oxfam, an international organization dedicated to fighting poverty, is proving that urine might be an invaluable source of electricity in refugee camps and other impoverished areas. For decades, utilities in developed countries have derived energy from the methane found wastewater, but in areas where such complex treatment schemes are not possible, simple solutions such as a “pee-power” toilet could offer an inexpensive and desperately needed source of energy.
Scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory demonstrated the first direct observation of increased radiative forcing due to increased carbon dioxide levels in the atmosphere. This study, published in Nature , is the first to provide direct observational evidence linking rising carbon dioxide concentrations to the greenhouse effect.
