Self-cooling solar cells boost power, last longer
Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells—keeping them cool, even in the blistering heat of the noonday Sun.
Highly efficient nanoparticles could bring down the cost of fuel cells
(Phys.org) —Fuel cells are a promising, non-polluting way to power cars, but their platinum catalysts are so expensive that there's no way current technology could be economically scaled up for widespread ...
Nano-scale gold particles are good candidates for drug delivery
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
Chemists develop technology to produce clean-burning hydrogen fuel
Rutgers researchers have developed a technology that could overcome a major cost barrier to make clean-burning hydrogen fuel – a fuel that could replace expensive and environmentally harmful fossil fuels.
Human cells' protein factory has an alternate operating manual
Working with a gene that plays a critical role in HIV infection, University of Maryland researchers have discovered that some human genes have an alternate set of operating instructions written into their ...
Engineers figure out how to make more efficient fuel cells
Solar power and other sources of renewable energy can help combat global warming but they have a drawback: they don't produce energy as predictably as plants powered by oil, coal or natural gas. Solar panels ...
Atomic structure of key muscle component revealed
Actin is the most abundant protein in the body, and when you look more closely at its fundamental role in life, it's easy to see why. It is the basis of most movement in the body, and all cells and components ...
Fukushima monkeys show possible 'effects of radiation'
Monkeys near the stricken Fukushima nuclear power plant have lower blood cell counts than cousins living further away, possibly because of radiation exposure, a study said Thursday.
Four billion-year-old chemistry in cells today
Parts of the primordial soup in which life arose have been maintained in our cells today according to scientists at the University of East Anglia.
Cost-effective, solvothermal synthesis of heteroatom (S or N)-doped graphene developed
A research team led by group leader Yung-Eun Sung has announced that they have developed cost-effective technology to synthesize sulfur-doped and nitrogen-doped graphenes which can be applied as high performance electrodes ...
A new approach to creating organic zeolites
Yushan Yan, Distinguished Professor of Engineering at the University of Delaware, is known worldwide for using nanomaterials to solve problems in energy engineering, environmental sustainability and electronics.
Photosensitive version of amiloride allows regulating the function of sodium-specific ion channels with light
The diuretic agent amiloride is used for the treatment of high blood pressure. Ludwig Maximilian University of Munich researchers have now synthesized a photosensitive version, which allows regulating the ...
Bacteria swim with whole body, not just propellers
When it comes to swimming, the bodies of some bacteria are more than just dead weight, according to new research from Brown University.
When temperatures get cold, newly-discovered process helps fruit flies cope
Cold-blooded animals cannot regulate their body temperature, so their cells are stressed when facing temperature extremes. Worse still, even at slightly colder temperatures, some biological processes in the ...
