Aircraft wheel and brake assemblies can become very hot during braking as the planes kinetic energy is transformed into heat by brake pads and dissipated into the surrounding components. The wheel, the tyres, the piston that clamps the pads into place and the metal housing of the brakes are all subject to sudden and intense heat. Now a new aluminium alloy eases manufacturers fears of failure by handling the heat better.
The new alloy therefore forms a key component of a carbon aircraft brake and wheel system as the wheels made from the alloy have to withstand the intense heat generated as the pistons press the carbon disks against each other, stopping the plane and dissipating the plane’s kinetic energy as heat.
Carbon brakes offer constant performance hot or cold, are unaffected by thermal shock or mechanical fatigue and offer unrivalled endurance. For a given level of energy absorption, carbon is three times lighter than steel allowing more passengers and cargo onboard.

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
