Rice University physicists (from left) Liyang Chen, Panpan Zhou and Doug Natelson and colleagues at Brookhaven National Laboratory and the University of Connecticut found evidence of electron pairing -- a hallmark feature of superconductivity -- at temperatures and energies well above the critical threshold where superconductivity occurs. The research appears this week in Nature.

(A) Photoluminescence and (B) electroluminsecence in low-dimensional and 3D perovskite-based devices. Photoluminescence (PL) refers to the emission of light caused by the absorption of incident photons, whereas electroluminescence (EL) is the emission of light owing to the energy supplied by an electric current. Although low-dimensional perovskite exhibits better PL properties than 3D perovskite, the latter has better EL properties, which can be exploited to design very bright and efficient PeLEDs.

Optical micrographs showing transition of stage-2 GIC to stage-1 HOPG GIC. Reflected light. The stage-2 areas are greenish-white. The stage-1 areas are blue. The red-colored areas are the mixed stage. Note, the greenish tint of graphite surface on panels (a,b) is the artifact of the digital processing; the actual color is almost white. The white shapeless feature on the right of the micrographs is an air bubble. Acquired with the SPI-3 HOPG sample.

Pumped storage hydropower uses dual-reservoir "storage" systems to improve the availability of energy by pumping and releasing water between the reservoirs to generate electricity to meet peak demands. To accelerate pumped storage hydropower implementation, SwRI is developing different strategies for efficiently building the reservoirs, illustrated here with an upper reservoir sited atop a mesa and a lower reservoir created by damming canyons below.

(a) Schematic illustration of the ion concentration profiles with asymmetric transmembrane temperature differences. (b) Electric power under different temperature differences. (c) At small transmembrane concentration intensities, both positive and negative temperature differences contribute to the electric power. At high transmembrane concentration intensities, a negative temperature difference promotes the power extraction and a positive temperature difference hinders the electric power.

This artist's illustration shows an alien world that is losing magnesium and iron gas from its atmosphere. The observations represent the first time that so-called "heavy metals" -- elements more massive than hydrogen and helium -- have been detected escaping from a hot Jupiter, a large gaseous exoplanet orbiting very close to its star.The planet, known as WASP-121b, orbits a star brighter and hotter than the Sun. The planet is so dangerously close to its star that its upper atmosphere reaches a blazing 4,600 degrees Fahrenheit, about 10 times greater than any known planetary atmosphere. A torrent of ultraviolet light from the host star is heating the planet's upper atmosphere, which is causing the magnesium and iron gas to escape into space. Observations by Hubble's Space Telescope Imaging Spectrograph have detected the spectral signatures of magnesium and iron far away from the planet.The planet's "hugging" distance from the star means that it is on the verge of being ripped apart by the star's gravitational tidal forces. The powerful gravitational forces have altered the planet's shape so that it appears more football shaped.The WASP-121 system is about 900 light-years from Earth.

The traditional Japanese basket weaving pattern (kago-mé: basket with eyes) served as an inspiration for an array of fluxon traps produced with a helium-ion microscope in a high-temperature superconductor. The anchored fluxons are represented by blue figures (based on the symbol Φ0 for the flux quantum), the purple fluxons are trapped by their neighbors like in a cage.
