Penn team uses self-assembly to make molecule-sized particles with patches of charge
Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge. view more (2009-10-21)
Novel polymer delivers genetic medicine, allows tracking
Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel into cells, deliver genetic cargo, and packs a beacon so scientists can follow its movements in living systems. view more (2009-10-07)
Deputy Prime Minister John Prescott launches New Research into Environmentally Friendly Plastics at University of Warwick
Rt Hon John Prescott MP, Deputy Prime Minister and Secretary of State for the Environment, Transport and the Regions will launch a research group dedicated to find more environmentally friendly ways to both and dispose of plastics. The launch will take place at 6pm today Tuesday 1st May in the International Manufacturing Centre at the University... view more... (2001-05-01)

Stealth nano particles may some day target tumor cells and deliver medication to specific body locations, according to Penn State chemical engineers. view more (2005-09-01)
NEW APPROACH TO STICKY PROBLEM
"Over the past 20 years people have been trying to develop techniques for studying structures of polymer surfaces to understand how these determine their adhesive performance," says Dr Leggett of the Manchester research team. "However, such surfaces are extremely difficult to study directly. They degrade very quickly under beams of... view more... (1999-11-04)
Appliance of science tackles UK fridge mountain
PIONEERING technology developed at Manchester Metropolitan University is set to tackle Britain`s growing fridge mountain and help save the environment. Scientists in the Department of Chemistry and Materials have developed the technique in response to new CFC controls which ban the consignment of fridges to landfill waste sites. Britons throw out... view more... (2002-03-01)
UD scientists discover new class of polymers
For years, polymer chemistry textbooks have stated that a whole class of little molecules called 1,2-disubstituted ethylenes could not be transformed into polymers-the stuff of which plastics and other materials are made. view more (2007-01-04)
See the force: Mechanical stress leads to self-sensing in solid polymers
Parachute cords, climbing ropes, and smart coatings for bridges that change color when overstressed are several possible uses for force-sensitive polymers being developed by researchers at the University of Illinois. view more (2009-05-07)
Living bandages
LIVING bandages tailored to individuals could help cure the incurable. Early studies suggest the dressings, which are coated with the patient`s own cells, can mend wounds that otherwise refuse to heal. Around 6 million people in Europe and the US have wounds that don`t heal properly. Pressure sores,... view more... (2002-01-09)
MIT crafts bacteria-resistant films
Having found that whether bacteria stick to surfaces depends partly on how stiff those surfaces are, MIT engineers have created ultrathin films made of polymers that could be applied to medical devices and other surfaces to control microbe accumulation. view more (2008-05-16)
Movie mountain
Will disposable DVDs lead to an eco-disaster of Hollywood proportions? GREEN campaigners are up in arms at the idea of a new disposable technology: throwaway DVDs. While the discs may save you the trouble of returning rental movies to the video shop, the worry is that they could cause environmental havoc.... view more... (2002-02-13)
Researchers use nanoparticles to deliver treatment for brain, spinal cord injuries
Purdue University researchers have developed a method of using nanoparticles to deliver treatments to injured brain and spinal cord cells. view more (2008-10-02)
Researchers develop detailed design rules for nanoimprint lithography processing
Using a combination of experimental data and simulations, researchers have identified key parameters that predict the outcome of nanoimprint lithography, a fabrication technique that offers an alternative to traditional lithography in patterning integrated circuits and other small-scale structures into polymers. view more (2006-04-24)
Spun-sugar fibers spawn sweet technique for nerve repair
Researchers at Purdue University have developed a technique using spun-sugar filaments to create a scaffold of tiny synthetic tubes that might serve as conduits to regenerate nerves severed in accidents or blood vessels damaged by disease. view more (2009-02-27)
More safety for cell phone batteries
Fraunhofer researchers will be presenting a novel lithium-ion battery at Hannover Messe on April 21 - 25. It is based on a polymer electrolyte, which is - unlike the liquid electrolyte in conventional lithium-ion batteries - not inflammable. A test set-up for redox flow batteries will also be on display at the show. view more (2008-04-14)
Iowa State researcher develops new treatment method for canine eye diseases
An Iowa State University researcher is exploring a new method of getting medicine to the eyes of infected dogs that is more effective and reliable than using eye drops. view more (2008-10-29)
Virginia Tech chemists create new polymers by adding DNA base pairs
Chemists at Virginia Tech are creating new polymers by adding DNA base pairs. Attributes include improved stretchable behavior and self-healing polymer films and coatings. view more (2006-09-13)
