New selective membranes in the form of thin hollow straws can improve water purification. This emerges from research by Joris de Gooth from UT's MESA+ research institute. The membranes that De Grooth jointly developed make it possible to purify water in a single process step, while preliminary treatment is always required in existing water treatment plants.
Gov. John Hickenlooper's task force on oil and gas discussed proposals Monday that would force energy companies to disclose all the chemicals they use in hydraulic fracturing and give local governments more of a say on where wells can be drilled. The task force is winnowing down a list of 56 suggestions from members before making its recommendations to Hickenlooper on ways to resolve disputes over local control and landowner rights.
A technology developed by Stanford Univ. scientists for passively probing the seafloor using weak seismic waves generated by the ocean could revolutionize offshore oil and natural gas extraction by providing real-time monitoring of the subsurface while lessening the impact on marine life.
Stacking perovskites onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell, according to a new study led by Stanford Univ. scientists. The researchers describe their novel perovskite-silicon solar cell in Energy & Environmental Science.
Foodborne illnesses kill roughly 3,000 Americans each year and about one in six are sickened, according to the Centers for Disease Control and Prevention. Yet most contaminated foods are never traced back to their source. That’s because existing methods to track tainted food following its supply chain from table to farm are highly inefficient, jeopardizing the health of millions and costing the food industry billions.
The Center for Nanoparticle Research at the Institute for Basic Science has succeeded in proposing a new method to enhance fuel cell efficiency with the simultaneous removal of toxic heavy metal ions. The direct methanol fuel cell (DFMC) has been a promising energy conversion device for electrical vehicles and portable devices. However, the inevitable carbon monoxide (CO) poisoning is one of the main factors reducing its performance.
Duke Univ. scientists have developed new forensic tracers to identify coal ash contamination in water and distinguish it from contamination coming from other sources. Previous methods to identify coal ash contaminants in the environment were based solely on the contaminants’ chemical variations. The newly developed tracers provide additional forensic fingerprints that give regulators a more accurate and systematic tool.
In the fight against global warming, carbon capture is gaining momentum, but standard methods are plagued by toxicity, corrosiveness and inefficiency. Using a bag of chemistry tricks, Cornell Univ. materials scientists have invented low-toxicity, highly effective carbon-trapping “sponges” that could lead to increased use of the technology.
During the 2014 R&D 100 Awards event, R&D Magazine expanded the banquet to hold four technology panels during the day. The last panel of the day focused on energy/environmental solutions and the innovation behind four R&D 100-winning technologies and the complexity of bringing such technologies to the market.
Rice Univ. scientists have discovered an environmentally friendly carbon-capture method that could be equally adept at drawing carbon dioxide emissions from industrial flue gases and natural gas wells. The Rice laboratory of chemist Andrew Barron revealed in a proof-of-concept study that amine-rich compounds are highly effective at capturing the greenhouse gas when combined with carbon-60 molecules.
Researchers at the Univ. of California, Los Angeles Henry Samueli School of Engineering and Applied Science have developed a more efficient way to turn methanol into useful chemicals, such as liquid fuels, and that would also reduce carbon dioxide emissions. Methanol, which is a product of natural gas, is well-known as a common “feedstock” chemical.

Wind turbines across the globe are being made taller to capture more energy from the stronger winds that blow at greater heights. But it’s not easy, or sometimes even economically feasible, to build taller towers, with shipping constraints on tower diameters and the expense involved in construction.
The boom in oil and gas produced through hydraulic fracturing, or fracking, is seen as a boon for meeting U.S. energy needs. But one byproduct of the process is millions of gallons of water that’s much saltier than seawater, after leaching salts from rocks deep below the surface. Now researchers at Massachusetts Institute of Technology and in Saudi Arabia say they have found an economical solution for removing the salt from this water.
Carbon capture and sequestration isn’t only suitable for new power plants, but more essential in retrofitting existing ones. Because of this retrofitting nature, carbon capture and sequestration is regarded by the International Energy Agency as the single technology most capable of carbon dioxide reduction in the world and could account for more than 20% of global carbon dioxide abatement by 2050.
Increasing the oil content of plant biomass could help fulfill the nation's increasing demand for renewable energy feedstocks. But many of the details of how plant leaves make and break down oils have remained a mystery. Now a series of detailed genetic studies conducted at Brookhaven National Laboratory reveals previously unknown biochemical details about those metabolic pathways.

Over a three-year period, Univ. of North Texas researchers developed and tested structured insulated panel building materials made from kenaf, a plant in the hibiscus family that is similar to bamboo. Kenaf fibers are an attractive prospect because they offer the same strength to weight ratio as glass fibers. The researchers found that the kenaf materials, including composite panels, provide up to 20% energy savings.
By opening and closing their beaks, shorebirds drive food-containing liquid drops into their throats. Researchers have mimicked this phenomenon by building simple, fog-collecting, rectangular “beaks” out of glass plates connected by a hinge on one side. Providing a large surface area where beads of fog condense, the “beak” improved collection rates over alternatives by up to 900 times.
Whenever there is a major spill of oil into water, the two tend to mix into a suspension of tiny droplets, called an emulsion, that is extremely hard to separate and can cause severe damage to ecosystems. A new membrane developed by Massachusetts Institute of Technology researchers can separate even these highly mixed fine oil-spill residues.
Soil pollution causes severe environmental and economic impacts, as well as risks for the human health and ecosystems. The closure of mining and industrial facilities in many sites across Europe has revealed large amounts of contaminated land with uncertain future uses. Decontaminating and recovering such soil is a long, complex and expensive process, which places a large burden on enterprises or public administrations.
A study published by Michigan State Univ. researchers this week concludes that helping farmers around the globe apply more precise amounts of fertilizer nitrogen can combat climate change. The study uses data from around the world to show that emissions of nitrous oxide, a greenhouse gas produced in soil following nitrogen addition, rise faster than previously expected when fertilizer rates exceed crop needs.
