Ultrafast charging of batteries using fully new anode material

By using a fully new material, nickel niobate, for the anode of lithium-ion batteries, the charging speed can be improved by ten times, according to researchers of the University of Twente. This is possible without the risk ...

When is a 'basin of attraction' like an octopus?

Mathematicians who study dynamical systems often focus on the rules of attraction. Namely, how does the choice of the starting point affect where a system ends up? Some systems are easier to describe than others. A swinging ...

Researchers zero in on methane released from reservoirs

Methane is a potent greenhouse gas that accounts for about a fifth of today's global warming. In addition to methane emitted from livestock and other agricultural practices, the gas is also spewed from the production, transport, ...

Model simulates global water supply

Hydropower, biomass power generation, wind power, hydrogen, photovoltaics—these terms quickly come to mind when talking about the energy mix of the future. An energy mix that is supposed to combat climate change by limiting ...
