New all-solid sulfur-based battery outperforms lithium-ion technology
(Phys.org) —Scientists at the Department of Energy's Oak Ridge National Laboratory have designed and tested an all-solid lithium-sulfur battery with approximately four times the energy density of conventional ...
Ambri liquid metal battery: Prototype deployment set for 2014
Researchers build 3-D structures out of liquid metal
(Phys.org) —Researchers from North Carolina State University have developed three-dimensional (3-D) printing technology and techniques to create free-standing structures made of liquid metal at room temperature.
'Going negative' pays for nanotubes: Team finds possible keys to better nanofibers, films
(Phys.org) —A Rice University laboratory's cagey strategy turns negatively charged carbon nanotubes into liquid crystals that could enhance the creation of fibers and films.
One chemical forms two colors of crystals, sheds insight on agostic bonds important in industrial catalysis
Chemists have unexpectedly made two differently colored crystals – one orange, the other blue – from one chemical in the same flask while studying a special kind of molecular connection called an agostic ...
Researchers create rollerball-pen ink to draw circuits
Hydrogel remembers its shape
(Phys.org)—A bit reminiscent of the Terminator T-1000, a new material created by Cornell researchers is so soft that it can flow like a liquid and then, strangely, return to its original shape.
Advanced electron microscope sheds light on metal embrittlement
Why does a solid metal that is engineered for ductility become brittle, often suddenly and with dramatic consequences, in the presence of certain liquid metal impurities?
Under pressure, sodium and hydrogen could undergo a metamorphosis, emerging as a superconductor
(PhysOrg.com) -- In the search for superconductors, finding ways to compress hydrogen into a metal has been a point of focus ever since scientists predicted many years ago that electricity would flow, uninhibited, through ...
Self-healing electronics could work longer and reduce waste
When one tiny circuit within an integrated chip cracks or fails, the whole chip or even the whole device is a loss. But what if it could fix itself, and fix itself so fast that the user never ...
New process yields high-energy-density, plant-based transportation fuel
(PhysOrg.com) -- A team of University of Wisconsin-Madison engineers has developed a highly efficient, environmentally friendly process that selectively converts gamma-valerolactone, a biomass derivative, into the chemical ...
Silicon can be made to melt in reverse
Like an ice cube on a warm day, most materials melt -- that is, change from a solid to a liquid state -- as they get warmer. But a few oddball materials do the reverse: They melt as they get cooler. Now a ...
Nanotech research yields bouncing liquid metal marbles (w/ video)
Coating liquid metal droplets in a nanoparticle mix creates an extra strong non-stick conductive material that retains its shape even under high impact, Australian research has found.
