Scientists have developed a new microscope that significantly improves the way heat flow in materials can be measured. This advancement could lead to better designs for electronic devices and energy ...

Heat is a ubiquitous form of energy that, unlike others, is notoriously difficult to store due to its natural tendency to dissipate. While this property is essential for phenomena like solar energy ...

New research from the Department of Energy's Oak Ridge National Laboratory, in collaboration with The Ohio State University and Amphenol Corporation, challenges conventional understanding about ...

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 ...

When we think about heat traveling through a material, we typically picture diffusive transport, a process that transfers heat from high-temperature to low-temperature as particles and molecules bump ...

Using a thermal sensor smaller than a grain of sand, engineers have measured the vibrations, or phonons, within individual molecules. Imagine you are playing the guitar -- each pluck of a string ...
