Tunneling across a tiny gap
Boston MA (SPX) Apr 09, 2015 -
Conduction and thermal radiation are two ways in which heat is transferred from one object to another: Conduction is the process by which heat flows between objects in physical contact, such as a pot of tea on a hot stove, while thermal radiation describes heat flow across large distances, such as heat emitted by the sun.
These two fundamental heat-transfer processes explain how energy mov ...

Water makes wires even more nano
Houston TX (SPX) Apr 09, 2015 -
Water is the key component in a Rice University process to reliably create patterns of metallic and semiconducting wires less than 10 nanometers wide. The technique by the Rice lab of chemist James Tour builds upon its discovery that the meniscus - the curvy surface of water at its edge - can be an effective mask to make nanowires.
The Rice team of Tour and graduate students Vera Abramova ...

Researchers observe new charge transport phenomenon
Aalto, Finland (SPX) Apr 09, 2015 -
Researchers of Aalto University in Finland and the German University of Marburg have collaborated in the study of the movement of charges over interfaces of semiconductor materials. The group noticed a new kind of transport phenomenon for charges. In the phenomenon, a pair formed by a negative electron and a positive charge moves onto an interface, after which its 'message' is passed on to the o ...

Light-powered gyroscope is world's smallest
San Francisco CA (SPX) Apr 09, 2015 -
A pair of light waves - one zipping clockwise the other counterclockwise around a microscopic track - may hold the key to creating the world's smallest gyroscope: one a fraction of the width of a human hair. By bringing this essential technology down to an entirely new scale, a team of applied physicists hopes to enable a new generation of phenomenally compact gyroscope-based navigation systems, ...

Researchers discover N-type polymer for fast organic battery
Houston TX (SPX) Apr 09, 2015 -
Researchers at the University of Houston have reported developing an efficient conductive electron-transporting polymer, a long-missing puzzle piece that will allow ultrafast battery applications.
The discovery relies upon a "conjugated redox polymer" design with a naphthalene-bithiophene polymer, which has traditionally been used for applications including transistors and solar cells. Wit ...

Next-gen temperature sensor to measure ocean dynamics
Lincoln NB (SPX) Apr 09, 2015 -
UNL engineers and the U.S. Naval Research Laboratory have designed a next-generation temperature sensor set to improve the measurement of oceanic dynamics that shape marine biology, climate patterns and military operations.
The fiber-optic sensor can register significantly smaller temperature changes at roughly 30 times the speed of existing commercial counterparts, said co-designer Ming H ...

US, Japan trust each other but both wary of China: poll
Tokyo (AFP) April 8, 2015 -
Over seven decades after Japan attacked Pearl Harbor and dragged the United States into a global war, Americans and Japanese overwhelmingly trust each other and are wary of China, an opinion poll has shown.
In contrast to the oft-heard calls from Beijing for more Japanese contrition over World War II, around two-thirds of Americans believe Tokyo has apologised enough or has no need to say so ...

Sun experiences seasonal changes, new research finds
Boulder CO (SPX) Apr 10, 2015 -
The Sun undergoes a type of seasonal variability with its activity waxing and waning over the course of nearly two years, according to a new study by a team of researchers led by the National Center for Atmospheric Research (NCAR). This behavior affects the peaks and valleys in the approximately 11-year solar cycle, sometimes amplifying and sometimes weakening the solar storms that can buffet Ea ...

Hubble finds phantom objects near dead quasars
Greenbelt MD (SPX) Apr 10, 2015 -
NASA's Hubble Space Telescope has photographed a set of wispy, goblin-green objects that are the ephemeral ghosts of quasars that flickered to life and then faded.
The glowing structures have looping, helical, and braided shapes. "They don't fit a single pattern," said Bill Keel of the University of Alabama, Tuscaloosa, who initiated the Hubble survey. Keel believes the features offer insi ...
