New small-scale generator produces alternating current by stretching zinc oxide wires
Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a flexible plastic substrate with two ends bonded. view more (2008-11-10)
Ovarian cancer responds to aspirin derivative with chemo
A new study using ovarian cancer cell lines shows promise in treating the deadly disease by combining the chemotherapy drug cisplatin with an aspirin-like compound to make recurrent cancer cells less resistant to the chemotherapy. view more (2006-02-16)
The sweet smell of nano-success
Materials scientists at Lehigh University and catalyst chemists at Cardiff University have uncovered secrets of the "nanoworld" that promise to lead to cleaner methods of producing, among other things, spices and perfumes. view more (2006-01-30)
Looking deeply into polymer solar cells
Researchers from the Eindhoven University of Technology and the University of Ulm have made the first high-resolution 3D images of the inside of a polymer solar cell. view more (2009-09-14)
New beryllium reference material for occupational safety monitoring
Researchers at the National Institute of Standards and Technology (NIST), in collaboration with private industry and other government agencies, have produced a new reference material for beryllium. view more (2009-09-23)
Widely used iron nanoparticles exhibit toxic effects on neuronal cells
Researchers at UC San Diego have discovered that iron-containing nanoparticles being tested for use in several biomedical applications can be toxic to nerve cells and interfere with the formation of their signal-transmitting extensions. view more (2007-03-29)
Researchers Reveal How Air Pollutant Helps Pregnant Women with Hypertension
Nitric oxide (NO) is best known as an air pollutant produced by vehicle emissions and power plants but for pregnant women it is a crucial compound required to avoid hypertension and pre-eclampsia. view more (2006-09-21)
Research helps understand factors that influence efficiency of organic-based devices
Organic-based devices, such as organic light-emitting diodes, require a transparent conductive layer with a high work function, meaning it promotes injection of electron holes into an organic layer to produce more light. view more (2008-07-09)
Batteries get a boost at Rice
Need to store electricity more efficiently? Put it behind bars. That's essentially the finding of a team of Rice University researchers who have created hybrid carbon nanotube metal oxide arrays as electrode material that may improve the performance of lithium-ion batteries. view more (2009-02-10)
Silicon nanowires upgrade data-storage technology
Scientists at the National Institute of Standards and Technology (NIST), along with colleagues at George Mason University and Kwangwoon University in Korea, have fabricated a memory device that combines silicon nanowires with a more traditional type of data-storage. view more (2007-06-11)
Gender, coupled with diabetes, affects vascular disease development
Diabetes is associated with the development of vascular (blood vessel) disease. As we age, vascular disease becomes more common. view more (2007-08-16)
Cheaper LEDs from breakthrough in zinc oxide (ZnO) nanowire research, Nano Letters study says
Engineers at UC San Diego have synthesized a long-sought semiconducting material that may pave the way for an inexpensive new kind of light emitting diode (LED) that could compete with today's widely used gallium nitride LEDs, according to a new paper in the journal Nano Letters. view more (2007-01-04)
Preclinical Study Links Gene to Brain Aneurysm Formation
University of Cincinnati (UC) neurovascular researchers have identified a gene that-when suppressed or completely absent-may predispose a person to brain aneurysms. view more (2007-08-08)
UCF researcher's nanoparticles could someday lead to end of chemotherapy
Nanoparticles specially engineered by University of Central Florida Assistant Professor J. Manuel Perez and his colleagues could someday target and destroy tumors, sparing patients from toxic, whole-body chemotherapies. view more (2009-06-17)
Body's "wonder gas" could tackle asthma and heart disease
The body's all-pervasive "wonder gas" nitric oxide is giving up its secrets to a high-powered team of researchers at the Wolfson Institute for Biomedical Research at University College London and the knowledge may lead to new treatments for asthma, heart disease, joint problems and a range of other conditions. The work is being led by... view more... (2000-04-10)
Novel light-sensitive compounds show promise for cancer therapy
Chemists at the University of California, Santa Cruz, have developed novel compounds that show promise for photodynamic cancer therapy, which uses light-activated drugs to kill tumor cells. view more (2009-06-17)
Pluronic L-81 is a potential anti-diabetic drug?
Pluronic surfactants are synthetic copolymers based on ethylene oxide and propylene oxide. view more (2009-07-08)
People are more suggestible under laughing gas
The pain-relieving effects of nitrous oxide - laughing gas - may be enhanced by suggestion or hypnosis, according to a new study by UCL (University College London). The study's findings - that people are more suggestible under the gas - mean that dental patients may benefit from being coached to relax while undergoing sedation. view more (2009-01-09)
Study shows direct link between leptin and obesity-related cardiovascular disease
Obese people who don't have high cholesterol or diabetes might think they're healthy - despite the extra pounds. view more (2008-11-11)
Active ingredient in common Chinese herb shown to reduce hypertension
Some 50 million Americans have hypertension, that is, blood pressure measuring above the normal range (less than 120/80 mmHg). If untreated, it can lead to heart attacks, strokes, or kidney disease. Lifestyle changes are the first-stage treatment for the disease, but if they fail, medications are prescribed. view more (2007-01-19)
