WEST LAFAYETTE, Ind. - Researchers have taken a step toward practical applications for "hyperbolic metamaterials," ultra-thin crystalline films that could bring optical advances including powerful microscopes, quantum computers and high-performance solar cells. New developments are reminiscent of advances that ushered in silicon chip technology, said Alexandra Boltasseva, a Purdue University associate professor of electrical and computer engineering.
Causes of Great Lakes Smelt Population Decline Are Complex
WEST LAFAYETTE, Ind. - The reasons for the dwindling population of smelt prey fish in the Great Lakes to near historic lows are more complicated than previously believed, new research from Purdue University and collaborators suggests.
Hydrogel Baits Offer Novel Way to Manage Invasive Ants
WEST LAFAYETTE, Ind. - Water-storing crystals known as hydrogels can effectively deliver pesticide bait to invasive Argentine ants, quickly decimating a colony, a Purdue University study finds.
Study: Listeria Pathogen Is Prevalent, Persistent in Retail Delis
WEST LAFAYETTE, Ind. - Purdue University research shows that standard cleaning procedures in retail delis may not eradicate Listeria monocytogenes bacteria, which can cause a potentially fatal disease in people with vulnerable immune systems. A study led by Haley Oliver, assistant professor of food science, found that 6.8 percent of samples taken in 15 delis before daily operation had begun tested positive for L. monocytogenes (mah-noh-sy-TAH'-gin-eez).
Chances of Saving with Solar Energy Greater for Indiana Farms Than Homes
WEST LAFAYETTE, Ind. - The probability of saving money by using solar energy rather than standard grid electricity is 92 percent for Indiana farm businesses and about 50 percent for homes, Purdue University energy economists find.
Pharmaceuticals, Personal Care Products Could Taint Swimming Pools
WEST LAFAYETTE, Ind. -- A new study suggests pharmaceuticals and chemicals from personal care products end up in swimming pools, possibly interacting with chlorine to produce disinfection byproducts with unknown properties and health effects.
Findings Point to Potential Approach to Treat Virus Causing Illness, Possible Paralysis
WEST LAFAYETTE, Ind. - New research findings point toward a class of compounds that could be effective in combating infections caused by enterovirus D68, which has stricken children with serious respiratory infections and might be associated with polio-like symptoms in the United States and elsewhere.
New Conversion Process Turns Biomass 'Waste' into Lucrative Chemical Products
A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel for racecars and jets.
Study: Invasive Species Can Dramatically Alter Landscapes
WEST LAFAYETTE, Ind. - Invasive plant and animal species can cause dramatic and enduring changes to the geography and ecology of landscapes, a study from Purdue University and the University of Kentucky shows.
