Scientists increase lithium-sulfur battery lifetime by a factor of 10
New clues from the dawn of the solar system
A research group in the UA Lunar and Planetary Laboratory has found evidence in meteorites that hint at the discovery of a previously unknown region within the swirling disk of dust and gas known as the protoplanetary ...
Engineers efficiently 'mix' light at the nanoscale
The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but ...
Hydrogen sulfide nanoreporters gather intel on oil before pumping
(Phys.org) —Scientists at Rice University have created a nanoscale detector that checks for and reports on the presence of hydrogen sulfide in crude oil and natural gas while they're still in the ground.
Researchers quantify toxic ocean conditions during major extinction 93.9 million years ago
Oxygen in the atmosphere and ocean rose dramatically about 600 million years ago, coinciding with the first proliferation of animal life. Since then, numerous short lived biotic events—typically marked ...
Nanoscale engineering boosts performance of quantum dot light emitting diodes
(Phys.org) —Dramatic advances in the field of quantum dot light emitting diodes (QD-LEDs) could come from recent work by the Nanotechnology and Advanced Spectroscopy team at Los Alamos National Laboratory.
Tetrapod nanocrystals light the way to stronger polymers
Fluorescent tetrapod nanocrystals could light the way to the future design of stronger polymer nanocomposites. A team of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory ...
Feast clue to smell of ancient Earth
Tiny 1,900 million-year-old fossils from rocks around Lake Superior, Canada, give the first ever snapshot of organisms eating each other and suggest what the ancient Earth would have smelled like.
Engineers enable 'bulk' silicon to emit visible light for the first time
Electronic computing speeds are brushing up against limits imposed by the laws of physics. Photonic computing, where photons replace comparatively slow electrons in representing information, could surpass ...
Searching for the solar system's chemical recipe
(Phys.org)—By studying the origins of different isotope ratios among the elements that make up today's smorgasbord of planets, moons, comets, asteroids, and interplanetary ice and dust, Mark Thiemens and ...
Lava dots: Scientists make hollow, soft-shelled quantum dots
(Phys.org)—Serendipity proved to be a key ingredient for the latest nanoparticles discovered at Rice University. The new "lava dot" particles were discovered accidentally when researchers stumbled upon ...
Researchers make first all-optical nanowire switch
(Phys.org)—Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1's and 0's were represented by bursts of light, instead of electricity.
Nanotube electrodes improve solar cells, could yield low-cost, efficient alternative
Forests of carbon nanotubes are an efficient alternative for platinum electrodes in dye-sensitized solar cells (DSC), according to new research by collaborators at Rice University and Tsinghua University.
Down to the wire: Inexpensive technique for making high quality nanowire solar cells developed
(PhysOrg.com) -- Solar or photovoltaic cells represent one of the best possible technologies for providing an absolutely clean and virtually inexhaustible source of energy to power our civilization. However, ...
