Fitting a square peg in a round hole—the surprising structure of uranium bound in hematite
One promising approach to stabilize uranium contamination in soils is to envelop the radioactive uranium into iron-bearing minerals like hematite. But how well does uranium bind with hematite and for how long? Scientists ...
New two-dimensional material could revolutionize solar fuel generation
Following the isolation of graphene in 2004, a race began to synthesize new two-dimensional materials. These are single-layer substances with a thickness of between one atom and a few nanometers (billionths of a meter). They ...
Hematene joins parade of new 2-D materials—Team extracts 3-atom-thick sheets from common iron oxide
In the wake of its recent discovery of a flat form of gallium, an international team led by scientists from Rice University has created another two-dimensional material that the researchers said could be a game changer for ...
Atoms rearrange in electrolyte and control ion flow under tough conditions
Minerals that make up rocks and soils are thrown out of equilibrium when the chemistry of their surroundings changes. Shifts in pH or the concentration of ions in water make minerals dissolve, grow, or react in other ways. ...
Martian ridge brings out rover's color talents
Color-discerning capabilities that NASA's Curiosity rover has been using on Mars since 2012 are proving particularly helpful on a mountainside ridge the rover is now climbing.
Hematite-based nanowire structures to enhance solar-to-fuel conversion in photoelectrochemical water splitting
ICN2 researchers led by ICREA Prof. Jordi Arbiol, in collaboration with the IREC and ICIQ, have produced a material for use in photoelectrochemical water splitting that is not only cheaper than existing alternatives, but ...
More solar power thanks to titanium
Earth-abundant, cheap metals are promising photocatalytic electrode materials in artificial photosynthesis. A team of Chinese scientists now reports that a thin layer of titania beneath hematite nanorods can boost the performance ...
Move over, Superman! NIST method sees through concrete to detect early-stage corrosion
When you suffer a fall, an on-the-field collision or some other traumatic blow, the first thing the doctor will do is take an X-ray, CT scan or MRI to determine if anything has been damaged internally. Researchers at the ...
Hematite-rich deposits in Capri Chasma
Capri Chasma is located in the eastern portion of the Valles Marineris canyon system on Mars, the largest known canyon system in the Solar System. Deeply incised canyons such as this are excellent targets for studying the ...
