Meeting the 'grand challenge' of a sustainable water supply
24-05-2013
Scientists and engineers must join together in a major new effort to educate the public and decision makers on a crisis in providing Earth's people with clean water that looms ahead in the 21st century. That's the focus of a comment article in the current edition of Chemical & Engineering ...
More emphasis needed on recycling and reuse of Li-ion batteries
24-05-2013
The discovery of potential environmental and human health effects from disposal of millions of rechargeable lithium-ion batteries each year has led scientists to recommend stronger government policies to encourage recovery, recycling and reuse of lithium-ion (Li-ion) battery materials. That's ...
Keeping fruit, vegetables and cut flowers fresh longer
16-05-2013
New technology offers the promise of reducing billions of dollars of losses that occur each year from the silent, invisible killer of fruits, vegetables and cut flowers — a gas whose effects are familiar to everyone who has seen bananas and other fruit ripen too quickly and rot. That's the ...
New evidence on how fluoride fights tooth decay
03-05-2013
In an advance toward solving a 50-year-old mystery, scientists are reporting new evidence on how the fluoride in drinking water, toothpastes, mouth rinses and other oral-care products prevents tooth decay. Their report appears in the ACS journal Langumir.Karin Jacobs and colleagues explain ...
A better alternative to gasoline
Cost-saving measure to upgrade ethanol to butanol
15-04-2013
Scientists reported a discovery that could speed an emerging effort to replace ethanol in gasoline with a substantially better fuel additive called butanol, which some experts regard as "the gasoline of the future." Duncan Wass explained that ethanol has become a leading biofuel — millions of ...
'Seeing' the flavor of foods
15-04-2013
The eyes sometimes have it, beating out the tongue, nose and brain in the emotional and biochemical balloting that determines the taste and allure of food, a scientist said. He described how people sometimes "see" flavors in foods and beverages before actually tasting them. "There have been ...
New test for skin sensitization without using animals
02-04-2013
In an advance in efforts to reduce the use of animals in testing new cosmetic and other product ingredients for skin allergies, scientists are describing a new, highly accurate non-animal test for these skin-sensitizers. Their study appears in ACS' journal Chemical Research in ...
The hunt for a successor to lithium for bipolar disorder
02-04-2013
Toxicity problems and adverse side effects when taking lithium, the mainstay medication for treating bipolar disorder, are fostering a scientific hunt for insights into exactly how lithium works in the body — with an eye to developing a safer alternative, published in the current edition of ...
A milestone for new carbon-dioxide capture/clean coal technology
22-03-2013
An innovative new process that releases the energy in coal without burning — while capturing carbon dioxide, the major greenhouse gas — has passed a milestone on the route to possible commercial use, scientists are reporting. Their study in the ACS journal Energy & Fuels describes results of ...
Thin films of nickel and iron oxides yield efficient solar water-splitting catalyst
Basic University of Oregon research shows promise in efforts to get hydrogen fuel from sunlight and water
22-03-2013
University of Oregon chemists say that ultra-thin films of nickel and iron oxides made through a solution synthesis process are promising catalysts to combine with semiconductors to make devices that capture sunlight and convert water into hydrogen and oxygen gases. Researchers in the Solar ...
