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 ...

Researchers have developed a method to control the direction of heat flow in crystals. This miniature device could eventually be used to create advanced thermal-management systems in electronic ...

Scientists show how a single atom can precisely control heat flow in molecules, opening new paths for efficient ...

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 ...

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 ...

There are two golden rules to thermal design: start simple and start early. The heat-flow path from the junction to the ambient, usually air in the local environment, determines a component’s ...

Light exposure switches heat flow in barium titanate by altering its structure, offering a reversible method for dynamic thermal control in ferroelectric materials. (Nanowerk Spotlight) We can switch ...

Researchers in the US have revealed that heat does not flow as expected between different materials when they are in a super-hot, ultra-dense state known as high-energy-density plasma. The experiment, ...
