Toward the end of their lives, low-mass stars undergo an abrupt dip in brightness, also known as the luminosity bump. While ...

Across the science fiction stories, you find three responses to entropy: annihilation, resistance and preservation ...

Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser ...

A challenge in materials design is that in both natural and manmade materials, volume sometimes decreases, or increases, with increasing temperature. While there are mechanical explanations for this ...

Precise micromachining of refractory high-entropy alloys keeps a significant challenge for inherent brittleness and low thermal conductivity. In this work, water-jet guided laser technology enables a ...
