Portable kit can recover traces of chemical evidence

11-Jan-2016

A chemist at the National Institute of Standards and Technology (NIST) has developed a portable version of his method for recovering trace chemicals such as environmental pollutants and forensic evidence including secret graves and arson fire debris. If successfully commercialized by industry, ...

Team may have a key solution to reducing carbon dioxide emissions

08-Jan-2016

Meeting the Paris Climate Agreement goal of limiting the increase in the global average temperature to well below two degrees Celsius compared to pre-industrial levels will require increased use of renewable energy and reducing the CO2 intensity of fossil energy use. The intermittency of when the ...

New technique both enhances oil recovery and sequesters carbon dioxide

21-Dec-2015

A proposed recovery technique for oil extraction developed by a Penn State-led research team not only outperforms existing drilling and recovery techniques, but also has the potential to sequester more carbon dioxide in the process. The team estimated that companies using this new technique would ...

Technique could set new course for extracting uranium from seawater

21-Dec-2015

An ultra-high-resolution technique used for the first time to study polymer fibers that trap uranium in seawater may cause researchers to rethink the best methods to harvest this potential fuel for nuclear reactors. The work of a team led by Carter Abney, a Wigner Fellow at the Department of ...

Fracking plays active role in generating toxic metal wastewater

17-Dec-2015

The production of hazardous wastewater in hydraulic fracturing is assumed to be partly due to chemicals introduced into injected freshwater when it mixes with highly saline brine naturally present in the rock. But a Dartmouth study investigating the toxic metal barium in fracking wastewater finds ...

Some gas produced by hydraulic fracturing comes from surprise source

16-Dec-2015

Some of the natural gas harvested by hydraulic fracturing operations may be of biological origin--made by microorganisms inadvertently injected into shale by oil and gas companies during the hydraulic fracturing process, a new study has found. The study suggests that microorganisms including ...

Quick clean-up: New process turns decades into hours for mining-water purification

14-Dec-2015

Cleaning up the water left over from mining operations can literally take generations - 25 to 50 years on average - leaving billions of gallons of the precious resource locked up and useless. Now, a University of Florida researcher has figured out how to trim that time dramatically - to just two ...

Researchers work to fingerprint hydrofracking water quality

11-Dec-2015

Mary Beth Jones of Apalachin, N.Y., lives near "ground zero" of the hotly contested hydrofracking debate swirling across New York State. Her land sits above the gas-rich Marcellus Shale, and like many of her neighbors, Jones is concerned about risks of groundwater contamination associated with ...

Carbon capture analyst: 'Coal should stay in the ground'

04-Dec-2015

Serious flaws have been found in a decade's worth of studies about the best way to reduce greenhouse gas emissions and stabilize the climate. The findings, from the University of Michigan, are released as world leaders at COP21 attempt to negotiate the globe's first internationally binding ...

At the nanoscale, concrete proves effective for nuclear containment

Research shows concrete is a strong choice for the long-term confinement of nuclear waste

24-Nov-2015

One of the main challenges faced by the nuclear industry is the long-term confinement of nuclear waste. Concrete is one of the barrier materials commonly used to contain radionuclides, both in nuclear reactors and nuclear waste-storing facilities. For this reason, it is extremely important that ...
