Scientists challenge classical phenomenon that water always completely wets water
Viewed macroscopically at room temperature, when water contacts other water, it will spread out and finally both mix together. In 2009, Chinese researchers first reported observing the formation of a liquid ...
Smallest Swiss cross—made of 20 single atoms
The manipulation of atoms has reached a new level: Together with teams from Finland and Japan, physicists from the University of Basel were able to place 20 single atoms on a fully insulated surface at room ...
A cool approach to flexible electronics
A nanoparticle ink that can be used for printing electronics without high-temperature annealing presents a possible profitable approach for manufacturing flexible electronics.
After initial flop, Google will try again to launch Android TV
Google Inc. still imagines a world in which people talk to their TV, commanding it to switch from ESPN to YouTube, start playing "Orange Is the New Black" on Netflix or answer "What's the weather like tomorrow?"
Formation of organic thin-film transistors through room-temperature printing
Japanese researchers have established a process for forming organic thin-film transistors (TFTs), conducting the entire printing process at room temperature under ambient atmospheric conditions.
Continuous terahertz sources demonstrated at room temperature
Imagine a technology that could allow us to see through opaque surfaces without exposure to harmful x-rays, that could give us the ability to detect harmful chemicals and bio-agents from a safe distance, and that could enable ...
How NASA builds a space laser
To build a satellite that will measure all the bumps and dips of our dynamic Earth, engineers started with a black box, built of a composite honeycomb material to make it as light as possible.
World's best thermometer made from light
(Phys.org) —University of Adelaide physics researchers have produced the world's most sensitive thermometer – three times more precise than the best thermometers in existence.
A potential candidate for more efficient solid oxide bismuth and iridium fuel cells
(Phys.org) —Fuel cells for decentralized energy production require oxygen ion conductors: materials that can store oxygen as ions, and then transport and release it. German researchers have now found an ...
In the wake of high-profile battery fires, a safer approach emerges
As news reports of lithium-ion battery (LIB) fires in Boeing Dreamliner planes and Tesla electric cars remind us, these batteries—which are in everyday portable devices, like tablets and smartphones—have ...
Scientists discover channel used by catalyst to produce ammonia, vital for food and fuel crops
(Phys.org) —Mother Nature's helper in turning nitrogen from the air into ammonia is an enzyme called nitrogenase that uses molybdenum and iron; scientists want to learn natural catalyst's secrets and apply ...
Engineering students invent virtual fitting room for online shoppers (w/ video)
(Phys.org) —One blessing of the Internet: shopping conveniently online for clothes. One curse of the Internet: shopping conveniently online for clothes.
Scientists capture ultrafast snapshots of light-driven superconductivity
A new study pins down a major factor behind the appearance of superconductivity—the ability to conduct electricity with 100 percent efficiency—in a promising copper-oxide material.
Phage 'cocktail' wipes out 99 percent of E. coli in meat, spinach
(Phys.org) —Treating food products with select bacteriophages - viruses that target and kill bacteria - could significantly reduce concentrations of E. coli, a Purdue University study shows.
