Physicists measured how readily a current of electron pairs flows through 'magic-angle' graphene, a major step toward understanding how this unusual material superconducts. By determining how readily ...

Drones have the potential to enhance nuclear deterrence, but they also introduce significant risks in terms of escalation ...

But the experiments revealed some basic physics of how fractures work — particularly how a buildup of friction at the interface ... or sidelong, force, similar to those found at a strike-slip ...

Essentially, this aseismic motion — devoid of the kinetic energy that generates shaking ... Through laboratory experiments simulating earthquakes, they discovered that friction — the force governing ...

Using thermoreversible rough and patchy systems, we keep control over the kinetic pathway of gelation ... and noncentral forces (friction) while independently controlling particle properties through ...

When detonated in pure soft rock, the contact force distribution is more uniform, the main direction of contact force is not obvious. On the whole, the peak friction energy curves ... the peak kinetic ...

The bias in the barotropic tide is mainly related to the topography and the bottom friction coefficient ... 3.3 Relationship between the section distribution of near-inertial kinetic energy and wind ...
