Nanostructures enhance light trapping for solar fuel generation
Physicists discover 'magnetotoroidic effect'
Some nanoparticles commonly added to consumer products can significantly damage DNA
housands of consumer products—including cosmetics, sunscreens, and clothing—contain nanoparticles added by manufacturers to improve texture, kill microbes, or enhance shelf life, among other purposes. ...
Simple urine test uses nanotechnology to detect dangerous blood clotting
Life-threatening blood clots can form in anyone who sits on a plane for a long time, is confined to bed while recovering from surgery, or takes certain medications.
Nanoscale composites improve MRI: Researchers merge magnetic particles to detect, fight disease
(Phys.org) —Submicroscopic particles that contain even smaller particles of iron oxide could make magnetic resonance imaging (MRI) a far more powerful tool to detect and fight disease.
New mechanism converts natural gas to energy faster, captures CO2
(Phys.org) —North Carolina State University researchers have identified a new mechanism to convert natural gas into energy up to 70 times faster, while effectively capturing the greenhouse gas carbon dioxide ...
Champion nano-rust for producing solar hydrogen
EPFL and Technion researchers have figured out the "champion" nanostructures able to produce hydrogen in the most environmentally friendly and cheap manner, by simply using daylight.
Cutoff switch may limit spread, duration of oxygen minimum zones
A new study examining the impact of iron released from continental margin sediments has documented a natural limiting switch that may keep these ocean systems from developing a runaway feedback loop that ...
New research technique shows perennial sea ice cover came about earlier than thought
An unlikely route to ferroelectricity
(Phys.org) -- Ferroelectricity, which was first observed in the 1940s, is an interesting phenomenon involving the spontaneous (non-induced) formation of charge polarization (separation of charge) in certain ...
Rust never sleeps—Observations of electron hopping in iron oxide hold consequences for environment and energy
(Phys.org)—Rust—iron oxide—is a poor conductor of electricity, which is why an electronic device with a rusted battery usually won't work. Despite this poor conductivity, an electron transferred to ...
Optical magnetic microscope for high-resolution, wide-field cell imaging
Study Yields Surprising New Insight into High-Temp Superconductors
A new kind of metal in the deep Earth
(PhysOrg.com) -- The crushing pressures and intense temperatures in Earth's deep interior squeeze atoms and electrons so closely together that they interact very differently. With depth materials change. New ...
