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.
Tick Genome Reveals Inner Workings of a Resilient Blood-guzzler
WEST LAFAYETTE, Ind. - An international team of scientists led by Purdue University has sequenced the genome of the tick that transmits Lyme disease, the most common vector-borne illness in North America.
From Allergens to Anodes: Pollen Derived Battery Electrodes
WEST LAFAYETTE, Ind. - Pollens, the bane of allergy sufferers, could represent a boon for battery makers: Recent research has suggested their potential use as anodes in lithium-ion batteries. "Our findings have demonstrated that renewable pollens could produce carbon architectures for anode applications in energy storage devices," said Vilas Pol, an associate professor in the School of Chemical Engineering and the School of Materials Engineering at Purdue University.
Bed Bug Genome Uncovers Biology of a Pest on the Rebound
WEST LAFAYETTE, Ind. - Purdue University researchers participated in a multi-institute project that sequenced the genome of the common bedbug, a blood-sucking insect that has reemerged globally as a hardy pest capable of withstanding most major classes of insecticides. The genome of Cimex lectularius uncovers the genetic underpinning of bedbugs' unique biology and offers new targets for controlling them. Purdue entomologists Ameya Gondhalekar and Michael Scharf contributed to the international effort by annotating the bugs' antioxidant genes, which detoxify the blood they ingest
Bismuth-based Nanoribbons Show 'Topological' Transport, Potential for New Technologies
WEST LAFAYETTE, Ind. - Researchers have created nanoribbons of an emerging class of materials called topological insulators and used a magnetic field to control their semiconductor properties, a step toward harnessing the technology to study exotic physics and building new spintronic devices or quantum computers.
Microbots Individually Controlled Using 'Mini Force Fields'
WEST LAFAYETTE, Ind. - Researchers are using a technology likened to "mini force fields" to independently control individual microrobots operating within groups, an advance aimed at using the tiny machines in areas including manufacturing and medicine. Until now it was only possible to control groups of microbots to move generally in unison, said David Cappelleri, an assistant professor of mechanical engineering at Purdue University.
'Hydricity' Concept Uses Solar Energy to Produce Power Round-the-clock
WEST LAFAYETTE, Ind. - Researchers are proposing a new "hydricity" concept aimed at creating a sustainable economy by not only generating electricity with solar energy but also producing and storing hydrogen from superheated water for round-the-clock power production.
Including Plant Acclimation to Temperature Change Improves Climate Models
WEST LAFAYETTE, Ind. - Including plants' acclimation to changes in temperature could significantly improve the accuracy of climate models, a Purdue University study shows.
Dendrimer Technology Gets a Grip on Cell Proteins, Could Improve Cancer Treatment
WEST LAFAYETTE, Ind. - Purdue researchers have devised a way to capture the finer details of complex cell processes by using tiny synthetic particles known as dendrimers, a technology that could lead to more targeted treatment for cancer.
