Even if society is able to slow all greenhouse gas emissions and get to "net zero" by mid-century as targeted by nations of the world in the UN Paris Agreement, there is a lag built into the climate system primarily as a ...

On its surface, the work is deceptively simple: Shoot a high-power laser beam onto a piece of metal for a fraction of a second and see what happens. But researchers say the physics of laser welding is surprisingly complex. ...

When a material undergoes a phase transition from a disordered to an ordered state, its properties change and these changes are observed via macroscopic observables such as specific heat capacity measurements.

A sphere looks the same no matter how it is rotated. Squash it on one side, however, and this symmetry is broken. A similar change from a high-symmetry state to a low-symmetry state defines many phase transitions in solids ...

Old glass is not the same as new glass -- and the difference is not just due to manufacturing techniques. Unlike crystalline solids, glasses change as they age, increasing packing density and stability. Ideally, a glass should ...
