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 ...

Heat management at the nanoscale has long been a cornerstone of advanced technological applications, ranging from high-performance electronics to quantum computing. Addressing this critical challenge, ...

Most electricity is generated by using heat to produce steam, which then turns a turbine. Although this approach performs ...

Scientists used nanoscale gold metamaterials to supercharge heat transfer across tiny gaps, achieving up to four times more energy flow than similar conventional systems. The breakthrough could lead ...

Why heat flux (flow) is an important thermal parameter. How researchers have developed an innovative heat-flux sensor. Details on the performance of this sensor in flat and curved situations. We know ...

Differential scanning calorimetry (DSC) is a thermal analysis method that measures the difference between the rate of heat flow into a specimen and into a reference, measured as a function of ...

From smartphones to supercomputers, electronics have a heat problem. Modern computer chips suffer from microscopic “hotspots” with power density levels that exceed those of rocket nozzles and even ...
