Control of heat flow is crucial for thermal logic devices and thermal management, with theoretical exploration preceding limited experimental progress in actively controlling heat flow. The device ...

A group of scientists from China has developed a novel smart PV (SPV) window that can produce electricity while calibrating the amount of solar radiation entering a building. “Our study proposed an ...

To understand how heat normally flows, you could study the second law of thermodynamics – or wrap your hands around a hot mug of coffee. Both tell us that heat tends to flow toward cooler regions. As ...
