A novel voltage peak in the metal nanowire-superconductor hybrid structure
May 03, 2018 (SPX)
Particularly, the investigations on strong spin-orbit coupling or ferromagnetic nanowires with superconducting contacts have become a research highlight in conn...
A surprising new superconductor
May 02, 2018 (SPX)
David and his colleagues just published the new recipe: an ultrathin layer of rhenium sandwiched between layers of gold, each measuring 1/1000th the diameter of...
Water-based battery can store solar and wind energy
May 01, 2018 (SPX)
The prototype manganese-hydrogen battery, reported in Nature Energy, stands just three inches tall and generates a mere 20 milliwatt hours of electricity, which...
New materials for sustainable, low-cost batteries
May 01, 2018 (SPX)
Scientists from ETH Zurich and Empa - led by Maksym Kovalenko, Professor of Functional Inorganic Materials - are among those involved in researching and develop...
Topological insulator 'flips' for superconductivity
May 01, 2018 (SPX)
TIs with induced superconductivity are of paramount interest to physicists because they have the potential to host exotic physical phenomena, including the elus...
Nanowires could make lithium ion batteries safer
Apr 26, 2018 (SPX)
In lithium-ion batteries (LIBs), lithium ions move back and forth between electrodes through an electrolyte. Traditional LIBs have a liquid electrolyte made of ...
New testing of model improves confidence in the performance of ITER
Apr 23, 2018 (SPX)
In ITER, the international fusion facility being built in France to demonstrate the feasibility of fusion power, the device will heat both the free electrons an...
When superconductivity disappears in the core of a quantum tube
Apr 22, 2018 (SPX)
The scientists were then able to confirm an unusual state of matter that retains its insulation regardless of the level of attraction between the particles. Thi...
Some superconductors can also carry currents of 'spin'
Apr 22, 2018 (SPX)
Spin is a particle's intrinsic angular momentum, and is normally carried in non-superconducting, non-magnetic materials by individual electrons. Spin can be 'up...
A higher-energy, safer and longer-lasting zinc battery
Apr 22, 2018 (SPX)
Together with colleagues at the U.S. Army Research Laboratory (ARL) and National Institute of Standards and Technology (NIST), the UMD engineers combined old ba...
Thin film converts heat from electronics into energy
Apr 22, 2018 (SPX)
The thin-film system uses a process called pyroelectric energy conversion, which the engineers' new study demonstrates is well suited for tapping into waste-hea...
Lockheed delivers 17 MWh of GridStar lithium energy storage to Peak Power
Apr 20, 2018 (SPX)
"Peak Power Inc. is an innovative company that we are excited to collaborate with to deploy our robust, reliable GridStar Lithium systems," said Frank Armijo, v...
Porous salts for fuel cells
Apr 20, 2018 (SPX)
Porous organic materials are potentially useful for many applications, including catalytic systems, separation processes, and gas storage. Although these framew...
Electromagnetic wizardry: Wireless power transfer enhanced by backward signal
Apr 19, 2018 (SPX)
"The notion of a coherent absorber was introduced in a paper published back in 2010. The authors showed that wave interference can be used to control the absorp...
Army research rejuvenates older zinc batteries
Apr 18, 2018 (SPX)
The high-impact journal Nature Materials published a peer-reviewed paper based on this ground-breaking research April 16. In prior achievements, these scientist...
Filling lithium-ion cells faster
Apr 17, 2018 (SPX)
One of the most critical and time-consuming processes in battery production is the filling of lithium cells with electrolyte fluid following the placement the o...
Tungsten 'too brittle' for nuclear fusion reactors
Apr 16, 2018 (SPX)
By simulating the damage caused by high energy neutrons and alpha particles produced during the fusion process, the Huddersfield researchers have discovered tha...
The raw power of human motion
Apr 13, 2018 (SPX)
Triboelectric nanogenerators (TENGs) capture mechanical energy from their surroundings, such as vibrations and random motion produced by humans, and convert it ...
New technology could wean the battery world off cobalt
Apr 13, 2018 (SPX)
But now, a research team led by scientists at the University of California, Berkeley, has opened the door to using other metals in lithium-based batteries, and ...
