Varnishing plastics without orange skin
In industry plastic parts are mostly coated electrostatically. The ESTA process involves three stages of pre-treatment. A plasma based one produces conductive polymer coatings in a single-stage, thus reducing costs by about one third. It is being presented at the Hanover Fair. ---------- Nowadays, plastic automobile parts such as bumpers and... view more... (2002-04-16)
University of Pittsburgh School of Medicine researchers develop 'off-the-shelf' vascular grafts
University of Pittsburgh School of Medicine investigators have engineered artificial blood vessels from muscle-derived stem cells (MDSCs) and a biodegradable polymer that exhibit extensive remodeling and remain free of blockages when grafted into rats. view more (2007-06-18)
Brown Engineers Build a Better Battery - With Plastic
Brown University engineers have created a new battery that uses plastic, not metal, to conduct electrical current. The hybrid device marries the power of a capacitor with the storage capacity of a battery. view more (2006-09-14)
Fingerprints provide crucial clue to new nanofiber fabrication technique
Fingerprints are usually used to identify people but, this time, they gave Penn State chemical engineers the crucial clue needed to discover an easy, versatile new method for making nanofibers that have potential uses in advanced filtration as well as wound care, drug delivery, bioassays and other medical applications. view more (2006-01-27)
A plastic pill for periodontal problems
Rutgers scientists today announced a revolutionary new treatment for killing the bacteria that attack gum tissue during periodontal disease, while also promoting healing and the regeneration of tissue and bone around the teeth. view more (2006-09-15)
Findings could improve fuel cell efficiency
A new type of membrane based on tiny iron particles appears to address one of the major limitations exhibited by current power-generating fuel cell technology. view more (2008-03-20)
Separate signals through optical fibres for ultrafast home network
Dutch-sponsored researcher Christos Tsekrekos has investigated how a small network for at home or in a company can function optimally. His research analyses the MGDM technique (Mode Group Diversity Multiplexing) of the Eindhoven University of Technology. view more (2008-01-25)
Proteins in gel
Several thousand test fields are tightly packed together on the tiny surface of a biochip. They permit the rapid analysis of substances, e.g. for diagnosing allergens in the blood. view more (2009-06-25)
Plastic electronics for light diodes and prostheses
Is it possible to make components out of organic polymers (plastics) whose structure is such that severed nerves can grow right into them and connect with electrodes in a prosthetic hand, for example? This is one of the research fields for Tobias Nyberg at the Section for Biomolecular and Organic Electronics at Linköping University, Sweden.... view more... (2002-04-29)
Trojan horse for ovarian cancer -- nanoparticles turn immune system soldiers against tumor cells
In a feat of trickery, Dartmouth Medical School immunologists have devised a Trojan horse to help overcome ovarian cancer, unleashing a surprise killer in the surroundings of a hard-to-treat tumor. view more (2009-07-16)
Nanoballs deliver drugs
Dutch researcher Cristianne Rijcken has developed a new type of biodegradable nanoparticle. The spherical structures can encapsulate various fat-soluble medicines, which makes it easier to target tumour tissue. view more (2007-10-25)
Plastic with changeable conductivity developed by chemical engineer
Dr. Yueh-Lin (Lynn) Loo at The University of Texas at Austin has modified a plastic so its ability to carry an electrical current can be altered during manufacturing to meet the needs of future electronic devices. view more (2007-04-10)
Synthetic adhesive mimics sticking powers of gecko and mussel
Geckos are remarkable in their ability to scurry up vertical surfaces and even move along upside down. Their feet stick but only temporarily, coming off of surfaces again and again like a sticky note. But put those feet underwater, and their ability to stick is dramatically reduced. view more (2007-07-19)
Shape-memory polymers designed for biomedical applications
Researchers at the Georgia Institute of Technology are developing unique polymers, which change shape upon heating, to open blocked arteries, probe neurons in the brain and engineer a tougher spine. view more (2008-01-04)
Low-cost reusable material could facilitate capture of carbon dioxide from power plants
Researchers have developed a new, low-cost material for capturing carbon dioxide (CO2) from the smokestacks of coal-fired power plants and other generators of the greenhouse gas. Produced with a simple one-step chemical process, the new material has a high capacity for absorbing carbon dioxide - and can be reused many times. view more (2008-03-10)
Scientists use nanomaterials to localize and control drug delivery
Using nanotechnology, scientists from UCLA and Northwestern University have developed a localized and controlled drug delivery method that is invisible to the immune system, a discovery that could provide newer and more effective treatments for cancer and other diseases. view more (2008-01-23)
Conference report highlights new research into drug delivery to treat eye disease
Researchers are investigating microneedles, nanoparticles and polymer carriers as potential new techniques to combat the leading cause of visual impairment and blindness in the United States, according to a report from the Third Annual ARVO/Pfizer Ophthalmics Research Institute Conference. view more (2008-11-18)
Biomedical researchers create artificial human bone marrow in a test tube
Artificial bone marrow that can continuously make red and white blood cells has been created in a University of Michigan lab. view more (2008-12-23)
Paper electrified by copper particles
The Polymer Chemistry Research Group at the University of Helsinki, Finland, has succeeded in producing nano-sized metallic copper particles. view more (2009-03-16)
New thermal microscope chosen as Millennium Product
A new type of microscope that can look beneath the surface of an opaque material has been granted Millennium Product status. The news was announced by Trade and Industry Secretary Peter Mandelson at the CBI Conference in Birmingham today, Monday 2 November. The microscope is a product of collaborative research at Loughborough and Lancaster... view more... (1998-11-04)
