The current global supply of crude oil is expected to meet demand through 2050, but there may be a few more drops to squeeze out. By making use of a previously undesired side effect in oil recovery, researchers have developed a method that yields up to 20% more heavy oil than traditional methods. Tokyo University of Agriculture and Technology (TUAT) team published their results on August 24 in Energy & Fuels, a journal of the American Chemical Society.
Forensic science experts at Flinders University are refining an innovative counter-terrorism technique that checks for environmental DNA in the dust on clothing, baggage, shoes or even a passport. "This microscopic environmental trace evidence, based on soil geochemical, bacterial and fungal analysis would complement and enhance current forensic intelligence tools," lead researcher Dr Jennifer Young says in new research in Forensic Science International: Genetics.
A remote monitoring tool to help authorities manage public safety and environmental issues in recently abandoned coal mines has been developed by the University of Nottingham. The tool uses satellite radar imagery to capture millimetre-scale measurements of changes in terrain height. Such measurements can be used to monitor and forecast groundwater levels and changes in geological conditions deep below the earth's surface in former mining areas.
In a study that gives new meaning to the term "rock bottom," seismic researchers have discovered the underside of a rocky slab of Earth's lithosphere that has been pulled more than 400 miles beneath northeastern China by the process of tectonic subduction.
Scientists at The University of Tokyo used electron spectroscopy to probe the coordination structures formed by the silicon atoms in aluminosilicate glass. This work may lead to innovations in the touchscreen and solar panel sectors.
"The rate of present-day break-up is millimeters per year, so it will be millions of years before new oceans start to form," said Stamps, an assistant professor in the Virginia Tech College of Science.
Supercomputer simulations of planetary-scale interactions show how ocean storms and the structure of Earth's upper layers together generate much of the world's seismic waves. Decoding the faint but ubiquitous vibrations known as Love waves could yield insights about Earth's storm history, changing climate and interior.
A new model shows how brine on Jupiter's moon Europa can migrate within the icy shell to form pockets of salty water that erupt to the surface when freezing. The findings, which are important for the upcoming Europa Clipper mission, may explain cryovolcanic eruptions across icy bodies in the solar system.
Scientists have detected what they say are the sediments of a huge ancient lake bed sealed more than a mile under the ice of northwest Greenland--the first-ever discovery of such a sub-glacial feature anywhere in the world.
A group of Skoltech scientists developed machine learning (ML) algorithms that can teach artificial intelligence (AI) to determine oil viscosity based on nuclear magnetic resonance (NMR) data. The new method can come in handy for the petroleum industry and other sectors, which have to rely on indirect measurements to characterize a substance.
