Not all parts of a corn stalk are equal, and they shouldn't be treated that way when creating cellulosic ethanol, say Purdue University researchers. When corn stover is processed to make cellulosic ethanol, everything is ground down and blended together. But a research team found that three distinct parts of the stover—the rind, pith, and leaves—break down in different ways.
Purdue University has developed a system to analyze the historic response of U.S. Coast Guard search-and-rescue operations in the Great Lakes and assess the potential risks associated with hypothetical changes in the allocation of resources in the region.
Someday trees could provide more than just shade, scenery, and building materials. Purdue University researchers are studying how poplars might be turned into liquid fuel.
Researchers at Purdue University and NIST have created a device small enough to fit on a computer chip that converts continuous laser light into numerous ultrashort pulses, a technology that might have applications in more advanced sensors, communications systems, and laboratory instruments.
Purdue University will lead a new effort aimed at cutting fuel consumption in half for commercial vehicles by perfecting hybrid technologies for the world's burgeoning bus and truck fleets.
Purdue University is part of a national institute that received a grant of up to $35 million over the next five years from the U.S. Food and Drug Administration (FDA). The FDA awarded the grant to the National Institute for Pharmaceutical Technology and Education, or NIPTE, to improve manufacturing standards and ultimately cut health care costs, create jobs, and improve drug safety.
The biofuel industry will not be able to meet the cellulosic production requirements of the Renewable Fuel Standard without significant advancements in technology or investment, according to a National Academy of Sciences study prepared for Congress.
Purdue University researchers will use a portion of a $25 million grant to determine the potential of grasses as environmentally responsible bioenergy crops and to educate farmers and others about the findings.
Anti-caking agents in powdered products may hasten degradation of vitamin C instead of doing what they are supposed to do: protect the nutrient from moisture. A Purdue University team is studying deliquescence, a reaction in which humidity causes a crystalline solid to dissolve, in hopes to understand how anti-caking agents protect substances such as vitamin C from humidity.
A team of Purdue University researchers has invented a prototype water-disinfection system that could help the world's 800 million people who lack safe drinking water. The system uses the sun's ultraviolet radiation to inactivate waterborne pathogens. Sunlight is captured by a parabolic reflector and focused onto a UV-transparent pipe though which water flows continuously.
Purdue University scientists believe they have found an effective target for killing late-stage, metastatic prostate cancer cells. The team is focusing on the function of a gene called Polo-like kinase (Plk1), a critical regulator of the cell cycle. Plk1 is also an oncogene, which tends to mutate and can cause cancer.
Researchers are developing a new type of computer memory that could be faster than the existing commercial memory and use far less power than flash memory devices. The technology combines silicon nanowires with a "ferroelectric" polymer, a material that switches polarity when electric fields are applied, making possible a new type of ferroelectric transistor.
The first fluorescence-guided surgery on an ovarian cancer patient was performed using a cancer cell "homing device" and imaging agent created by a Purdue University researcher. The surgery was one of 10 performed as part of the first phase of a clinical trial to evaluate a new technology to aid surgeons in the removal of malignant tissue from ovarian cancer patients.
A study by researchers from the schools of science and medicine at Indiana University-Purdue University Indianapolis examines the effects of carbon nanoparticles on living cells. This work is among the first to study concentrations of these tiny particles that are low enough to mimic the actual exposure of an ordinary individual.
Purdue University researchers have found an alternative environmentally friendly and energy-efficient way to dry corn ethanol, and their proof is in the pudding. The Purdue team found that the shape and structure of tapioca pearls are ideal for removing water from ethanol.
Purdue University students are designing and building a rocket engine that might be used in a vehicle to land on the moon. These students are part of a team developing a rocket motor through the NASA-funded Project Morpheus, which includes research to develop new technologies for future trips to the moon, Mars, or asteroids.
The right combination of compounds produced by a beneficial fungus could lead to grasses that require fewer pesticides and are safer for wildlife and grazing animals, according to Purdue University scientists.
Researchers are making progress in creating digital transistors using a material called graphene, potentially sidestepping an obstacle thought to dramatically limit the material's use in computers and consumer electronics.
Researchers have created and tested miniature devices that are implanted in tumors to generate oxygen, boosting the killing power of radiation and chemotherapy. The technology is designed to treat solid tumors that are hypoxic at the center, meaning the core contains low oxygen levels.
A new tool developed by nuclear engineers at Purdue University will be hitched to an experimental fusion reactor at Princeton University to learn precisely what happens when extremely hot plasmas touch and interact with the inner surface of the reactor.
How people's moods and self-discipline affect their physical health and longevity will continue to be studied at Purdue University thanks to a $2.1 million, five-year grant from the National Institutes of Health.
A small group of researchers, including a team from Purdue University, has successfully created ultrapure material that captures new states of matter, a finding that could have applications in high-speed quantum computing.
Purdue University biologists identified a new way in which bacteria hijack healthy cells during infection, which could provide a target for new antibiotics.
Researchers are developing new technologies that combine laser and electric fields to manipulate fluids and tiny particles such as bacteria, viruses, and DNA for a range of potential applications, from drug manufacturing to food safety.
Once eggs are laid, their natural resistance to pathogens begins to wear down, but a Purdue Univ. scientist believes he knows how to rearm those defenses.
