Physicists who study superconductivity strive to create a clean, perfect sample. But a Purdue University team that has mapped seemingly random, four-atom-wide dark lines of electrons on the surface of copper-oxygen based superconducting crystals has discovered that they exist throughout the crystal. The findings suggest the lines, which are “flaws”, could play a role in the material's superconductivity at much higher temperatures than others.
Researchers have created a new type of biosensor that can detect minute concentrations of glucose in saliva, tears, and urine, and might be manufactured at low cost because it does not require many processing steps to produce.
Researchers have developed a design tool that enables people to create 3D objects with their bare hands by using a depth-sensing camera and advanced software algorithms to interpret hand movements and gestures.
Researchers have demonstrated tiny machines, called self-calibratable micro-electromechanical systems, or MEMS, that could make possible super-accurate sensors and motors. Although MEMS are in commercial use, the new device is the first of its kind capable of self-calibration, a step critical for applications requiring high performance and accuracy.
Sweet and biomass sorghum would meet the need for next-generation biofuels to be environmentally sustainable, easily adopted by producers, and take advantage of existing agricultural infrastructure, a group of researchers led by Purdue University scientists believes.
Researchers have proposed a method to automatically detect a new class of software glitches in smartphones called "no-sleep energy bugs," which can entirely drain batteries while the phones are not in use.
Professors from Purdue University and the University of North Carolina at Charlotte are bringing editors of academic journals together to reaffirm their commitment to research integrity.
U.S. researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail. Because international treaties forbid the detonation of nuclear test weapons, tools that can accurately depict an explosion are becoming critical for national defense.
A new Purdue University-developed process for creating biofuels has shown potential to be cost-effective for production scale, opening the door for moving beyond the laboratory setting.
More than 2 billion years ago, a much fainter sun should have left the Earth as an orbiting ice ball, unfit to develop life as we know it today. Why the Earth avoided the deep freeze is a question that has puzzled scientists, but Purdue University's David Minton believes he might have an answer.
Researchers are edging toward the creation of new optical technologies using "nanostructured metamaterials" capable of ultra-efficient transmission of light, with potential applications including advanced solar cells and quantum computing.
Gasoline prices this summer could stay relatively steady provided that an already-tense Middle East doesn't flare up and nothing else happens to disrupt supplies, a Purdue University economist says.
Researchers have shown how to create morphing robotic mechanisms and shape-shifting sculptures from a single sheet of paper in a method reminiscent of origami, the Japanese art of paper folding. The new method, called Kaleidogami, uses computational algorithms and tools to create precisely folded structures.
Researchers have created an ultrasensitive biosensor that could open up new opportunities for early detection of cancer and "personalized medicine" tailored to the specific biochemistry of individual patients. The device, which could be several hundred times more sensitive than other biosensors, combines the attributes of two distinctly different types of sensors.
Researchers have taken a step toward overcoming a key obstacle in commercializing "hyperbolic metamaterials," structures that could bring optical advances including ultrapowerful microscopes, computers, and solar cells. The researchers have shown how to create the metamaterials without the traditional silver or gold previously required.
A team of Purdue University researchers will use a $1.6 million federal grant to advance sensor technology and computer simulation tools for tracking and improving the performance and reliability of "smart" wind turbines and wind farms.
Researchers have created a next-generation zoom function to view and compare portions of complex graphics such as city maps, scientific images, or pages of text. The new tool, PolyZoom, makes it possible to simultaneously magnify many parts of a graphic without losing sight of the original picture.
In a study from Stanford University and Purdue University, researchers have shown for the first time that climate change may force the U.S. corn belt to move north in the next 10 years, escaping devastating heat waves. In turn, this will bring substantial price swings to the corn market, adversely affecting industries like food and biofuels.
Engineers at Purdue University have coated glass fibers with a new thermoelectric material formed by dipping glass fibers in a solution containing nanocrystals of lead telluride and then exposing them to heat in a process called annealing to fuse the crystals together. The resulting material is far less brittle and more effiicient to produce than conventional thermoelectrics.
The 725-acre Purdue Research Park of West Lafayette is the largest university-affiliated incubation complex in the country, and will soon get larger as Automotive Robotics Proving Labs Inc. plans to open a nearly 50,000-square-foot engine test facility and create 30 jobs.
A compound found in red wine, grapes, and other fruits, and similar in structure to resveratrol, is able to block cellular processes that allow fat cells to develop, opening a door to a potential method to control obesity, according to a Purdue University study.
Students in a Purdue University service-learning program have developed an application for Apple's iPad that helps children with severe autism learn how to communicate. The app, called SPEAKall!, allows the children to construct sentences by choosing photos and graphic symbols.
Researchers at the University of Notre Dame and Pennsylvania State University have announced breakthroughs in the development of tunneling field effect transistors (TFETs), a semiconductor technology that takes advantage of the quirky behavior of electrons at the quantum level.
Purdue University researchers have identified enzymes and biochemical compounds called lipids that are targeted and modified by the dengue virus during infection, suggesting a potential new approach to control the aggressive mosquito-borne pathogen.
While scientists believe conditions suitable for life might exist on the so-called "super-Earth" in the Gliese 581 system, Purdue University researchers say it's unlikely to be transferred to other planets within that solar system.
