Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Physicists have created a device that has experimentally exceeded the conventional second law of thermodynamics. The device is an information engine, which converts information into work, and it is ...

For more than a century, thermodynamics has described how heat flows and engines run, while quantum mechanics has ruled the ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

Physicists in Germany have come up with a way to convert the energy difference between two quantum states of a group of atoms into work. The device adapts the principles of the familiar classical ...

Quantum thermodynamics explores the fundamental principles governing energy conversion at the smallest scales, where quantum effects such as coherence and entanglement significantly influence the ...

Abstract: The aviation industry is undergoing significant improvements in aircraft efficiency, driven by technological innovation and evolving performance demands. In this lecture, we will explore the ...

When French engineer Sadi Carnot calculated the maximum efficiency of a heat engine in 1824, he had no idea what heat was. In those days, physicists thought heat was a fluid called caloric. But Carnot ...

Finite-time thermodynamics (FTT) is an advanced field that addresses the inherent irreversibilities associated with real-world energy conversion processes. Unlike classical thermodynamics which ...

The X-Engine technology used in the XTS-210 is a direct drive rotary approach that can be viewed as an "inverted" Wankel engine. It has a trochoidal rotor with a three-lobed housing, but it utilizes a ...
