(Phys.org)—In ytterbium nickel phosphide there is a quantum critical point between the ferromagnetic and non-magnetic states that was previously not thought possible.
Batteries: Scientists see how and where disruptive structures form and cause voltage fading
(Phys.org)—Starting as a few atoms long, thorns forming on the electrode's surface in a specialized lithium battery cause the battery to gradually fade, according to scientists at Pacific Northwest National ...
Pink diamond 'behaviour' solved but colour still a mystery
UWA scientists have explained the photochromic behaviour of the pink diamond in an attempt to uncover why they possess their pink colouration.
Disappearing light: Precision measurement of an atomic transition
(Phys.org)—Modern precision measurements are spectacular feats of engineering. An excellent example is determining the passage of time. Before John Harrison's marine chronometer in the mid 18th century, ...
The self-improvement of lithium-ion batteries
(Phys.org)—The search for clean and green energy in the 21st century requires a better and more efficient battery technology. The key to attaining that goal may lie in designing and building batteries not ...
IEA: Australia coal, gas exports 'to surge'
Australia's coal and gas exports will surge as its resource sector booms, but it faces challenges such as labour shortages and infrastructure bottlenecks, the International Energy Agency said Monday.
Rare earth metals: Will we have enough?
Life in the 21st century wouldn't be the same without rare earth metals. Cell phones, iPads, laptops, televisions, hybrid cars, wind turbines, solar cells and many more products depend on rare earth metals ...
'Smart growth' strategies curb car use, greenhouse gas emissions: study
A new study finds that smart growth approaches to urban planning could substantially reduce the number of miles that residents drive in a year. The research was published this week in The B.E. Journal of Economic Analysis an ...
Team introduces breakthrough in understanding of high-temperature superconductivity
Researchers from the University of Miami (UM) are unveiling a novel theory for high-temperature superconductivity. The team hopes the new finding gives insight into the process, and brings the scientific community closer ...
Graphite enters different states of matter
(Phys.org) -- For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second).
America's clean energy policies need a reality check
America's approach to clean energy needs to be reformed if it is to meaningfully affect energy security or the environment, according to two new articles by Stanford writers.
