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.
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.
Nanoshaping Method Points to Future Manufacturing Technology
WEST LAFAYETTE, Ind. - A new method that creates large-area patterns of three-dimensional nanoshapes from metal sheets represents a potential manufacturing system to inexpensively mass produce innovations such as "plasmonic metamaterials" for advanced technologies.
Germanium Comes Home to Purdue for Semiconductor Milestone
WEST LAFAYETTE, Ind. - A laboratory at Purdue University provided a critical part of the world's first transistor in 1947 - the purified germanium semiconductor - and now researchers here are on the forefront of a new germanium milestone. The team has created the first modern germanium circuit - a complementary metal-oxide-semiconductor (CMOS) device - using germanium as the semiconductor instead of silicon.
Toxin from Tobacco Smoke Could Increase Pain in Spinal Cord Injury
WEST LAFAYETTE, Ind. - A neurotoxin called acrolein found in tobacco smoke that is thought to increase pain in people with spinal cord injury has now been shown to accumulate in mice exposed to the equivalent of 12 cigarettes daily over a short time period.
Study: Fungus Behind Deadly Disease in Walnut Trees Mutates Easily, Complicating Control
WEST LAFAYETTE, Ind. - Researchers from Purdue and Colorado State universities have discovered that the fungus responsible for thousand cankers disease, a lethal affliction of walnut trees and related species, has a rich genetic diversity that may make the disease more difficult to control.
'Topological Insulators' Promising for Spintronics, Quantum Computers
WEST LAFAYETTE, Ind. - Researches have uncovered "smoking-gun" evidence to confirm the workings of an emerging class of materials that could make possible "spintronic" devices and practical quantum computers far more powerful than today's technologies.
Study: Farmers And Scientists Divided over Climate Change
WEST LAFAYETTE, Ind. - Crop producers and scientists hold deeply different views on climate change and its possible causes, a study by Purdue and Iowa State universities shows.
