New method to reduce the optical band gap of strontium titantate thin films
With the promise of sunlight into fuel, strontium titanate (SrTiO3) is widely studied. The problem is the optical band gap or the energy needed to get electrons to do work after being hit with light. At ...
Amputee puts limb system through its paces
Scientists find meteoritic evidence of Mars water reservoir
(Phys.org)—NASA and an international team of planetary scientists have found evidence in meteorites on Earth that indicates Mars has a distinct and global reservoir of water or ice near its surface.
Discovery advances ferroelectrics in quest for lower power transistors
(Phys.org)—An article released today by the journal Nature Materials describes the first direct observation of a long-hypothesized but elusive phenomenon called "negative capacitance." The work describes a uniq ...
Compact galaxy groups reveal details of their close encounters
(Phys.org)—Galaxies – spirals laced with nests of recent star formation, quiescent ellipticals composed mainly of old red stars, and numerous faint dwarfs – are the basic visible building blocks of ...
Past global warming similar to today's: Size, duration were like modern climate shift, but in two pulses
The rate at which carbon emissions warmed Earth's climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to ...

Massive study provides first detailed look at how Greenland's ice is vanishing
The Greenland Ice Sheet is the second-largest body of ice on Earth. It covers an area about five times the size of New York State and Kansas combined, and if it melts completely, oceans could rise by 20 feet. ...
Signs of Europa plumes remain elusive in search of Cassini data
(Phys.org)—A fresh look at data collected by NASA's Cassini spacecraft during its 2001 flyby of Jupiter shows that Europa's tenuous atmosphere is even thinner than previously thought and also suggests that ...

Researchers glimpse pathway of sunlight to electricity
Four pulses of laser light on nanoparticle photocells in a University of Oregon spectroscopy experiment has opened a window on how captured sunlight can be converted into electricity.
Research aims to improve rechargeable batteries by focusing on graphene oxide paper
A Kansas State University engineering team has discovered some of graphene oxide's important properties that can improve sodium- and lithium-ion flexible batteries.
