Rubber can be extracted from the juice of the dandelion, but transitioning this technology to the industrial setting has been a challenge. The Fraunhofer Institute in Germany has joined with Continental tire company to build the first-ever pilot system to extract vast quantities of dandelion rubber for making tires
In the midst of an intensifying global water crisis, scientists are reporting development of a more economical way to use one form of the “ice that burns” to turn very salty wastewater from fracking and other oil and gas production methods into water for drinking and irrigation. The method removes more than 90% of the salt.
This summer's "dead zone" at the bottom of the Gulf of Mexico, where there's so little oxygen that starfish suffocate, is bigger than average but doesn't approach record size as scientists had predicted, according to findings released this week. The area of low oxygen covers 5,840 square miles of the Gulf floor—roughly the size of Connecticut.
Researchers in Texas have discovered a new chemical reaction that has the potential to lower the cost and streamline the manufacture of compounds ranging from agricultural chemicals to pharmaceutical drugs. The reaction resolves a long-standing challenge in organic chemistry in creating phenolic compounds from aromatic hydrocarbons quickly and cheaply.
A landmark federal study on hydraulic fracturing, or fracking, shows no evidence that chemicals from the natural gas drilling process moved up to contaminate drinking water aquifers at a western Pennsylvania drilling site. After a year of monitoring, the researchers found that the chemical-laced fluids used to free gas trapped deep below the surface stayed thousands of feet below the shallower areas that supply drinking water
A family of molecules developed at Carnegie Mellon Univ. to break down pollutants in water is one step closer to commercial use. Recently published study results show that the molecules, which are aimed at removing hazardous endocrine disruptors from water sources, aren't endocrine disruptors themselves. They proved to be non-toxic to developing zebrafish embryos.
There is increasing pressure on the chemical and related industries to ensure that their products comply with increasing numbers of safety regulations. Researchers at the Univ. of Kansas have developed a computational technique that could allow the industry to predict whether a given compound will be toxic even at a low dose and thus allow alternatives to be found when necessary.
When petroleum companies abandon an oil well, more than half the reservoir’s oil is usually left behind as too difficult to recover. Now, however, much of the residual oil can be recovered with the help of nanoparticles and a simple law of physics. A partnership of Norwegian and Chinese scientists has succeeded in recovering up to 50% of residual in North Sea rock samples.
Are teeth the latest victims of bisphenol A (BPA)? Yes, according to the conclusions of a team lead by researchers in France. They have shown that the teeth of rats treated with low daily doses of BPA could be damaged the chemical.
A research collaboration agreement has been formed between imaging company FEI and the University of Oklahoma to establish an oil and gas center of excellence. Called the FEI-OU Pore Scale Characterization Laboratory, the center will focus on the development of routine quantitative methods to classify shales in the economic assessment of tight oil and gas plays.
A newly synthesized material might provide a dramatically improved method for separating the highest-octane components of gasoline. These components are expensive to isolate. Created in the laboratory of Jeffrey Long, professor of chemistry at the University of California, Berkeley, the material is a metal-organic framework, or MOF, which can be imagined as a sponge with microscopic holes.
Dow Chemical Co. said Tuesday it received a $2.2 billion payment from Petrochemical Industries Company of Kuwait, settling a dispute over a scrapped joint venture. A year ago, an international arbitration court awarded Dow $2.2 billion in damages stemming from Kuwait's move to withdraw from the joint venture.
Oil companies big and small have used technology to find a bounty of oil and natural gas so large that worries about running out have melted away. New imaging technologies let drillers find oil and gas trapped miles underground and undersea. The result is an abundance that has put the United States on track to become the world's largest producer of oil and gas in a few years.
t's a chemical that's been in U.S. households for more than 40 years, from the body wash in your bathroom shower to the knives on your kitchen counter to the bedding in your baby's basinet. But federal health regulators are just now deciding whether triclosan—the germ-killing ingredient found in an estimated 75% of antibacterial liquid soaps and body washes sold in the U.S.—is ineffective, or worse, harmful.
At the start of a major conference to regulate chemical and hazardous waste safety, top officials voiced optimism Saturday that delegates will approve new international controls on several industrial compounds and agree to clamp down on some cross-border pollution.
After China reported quarterly economic growth of 7.7% this week, global markets reacted by falling, wiping out billions of dollars in stock. The reason? Growth came in under the 8% expected by forecasters. The plunge highlighted complaints about the possible inaccuracy of Beijing's official data and the intense, possibly excessive importance traders attach to a handful of Chinese economic indicators.
Monsanto and Dow AgroSciences LLC said Thursday they reached a new licensing agreement to collaborate on biotech-engineered corn that is resistant to herbicide and insects. Under the agreement, Monsanto will license Dow's new Enlist weed control technology, which allows corn to tolerate weed-killing chemicals.
PPG has completed the sale of its $2.5 billion commodity chemicals business to Georgia Gulf, the companies said Monday. The combination of the former PPG unit and Georgia Gulf has been renamed Axiall Corp., which will start trading Tuesday on the New York Stock Exchange under the "AXLL" ticker.
The Dow Innovation Center, a new research facility to be located at the University of Illinois Urbana-Champaign, has recently been announced by Dow and will develop data management solutions. At the same time, Dow has entered into an industry partnership with the National Center for Supercomputing Applications, providing access to expertise and equipment which will accelerate Dow’s discovery processes.
Organophosphorus agents (OP) are used as pesticides in developing countries and it is estimated about 200,000 people die each year across the world from OP poisoning through occupational exposure, unintentional use, and misuse. Using a modified human enzyme, researchers in Europe have created a “bioscavenger” which was found to protect mice against these types of chemical agents.
According to a recent study, brine water that flows back from gas wells in the Marcellus Shale region after hydraulic fracturing is many times more salty than seawater, with high contents of various elements, including radium and barium. The findings show that these elements, found in high levels in the late stages of hydraulic fracturing, come from the ancient brines rather than from salts dissolved by the water and chemicals used as part of the fracking process.
Scientists at Battelle Memorial Institute have invented a novel, water-based polyurethane unlike any other—environmentally responsible, cost-effective, soy-based and free of N-methyl-2-pyrrolidone (NMP) solvent. This new polyurethane has less odor than its petroleum-based counterpart and can be used in a wide variety of coatings and adhesives.
In the Colorado mountains, a spike in air pollution has been linked to a boom in oil and gas drilling. About 800 miles away on the plains of north Texas, there's a drilling boom, too, but some air pollution levels have declined. Opponents of drilling point to Colorado and say it's dangerous. Companies point to Texas and say drilling is safe.
Claiming that recent product recalls and bans indicate that product manufacturers do not have adequate tools for identifying and avoiding the use of harmful chemicals in their products, a group of scientists from North America and Europe has developed a five-tiered testing system that manufacturers can use to ensure that the consumer products they produce are free of endocrine disrupting chemicals like BPA or DDT.
Geological and environmental challenges facing developers of renewable energy and shale gas resources will be a dominant at the fall meeting of the American Geophysical Union this week in San Francisco. Experts on shale gas and hydraulic fracturing will be speaking about enhanced geothermal technology, which takes advantage of fracking techniques to access deep well thermal energy, delivered as steam.
