What is heat conduction?

Heat is an interesting form of energy. Not only does it sustain life, make us comfortable and help us prepare our food, but understanding its properties is key to many fields of scientific research. For example, knowing how ...

Scientists solve decade-long mystery of nanopillar formations

Scientists at the California Institute of Technology have uncovered the physical mechanism by which arrays of nanoscale pillars can be grown on polymer films with very high precision, in potentially limitless patterns.

Opto-thermoelectric microswimmers

In a recent report, Xiaolei Peng and a team of scientists in materials science and engineering at the University of Texas, U.S., and the Tsinghua University, China, developed opto-thermoelectric microswimmers bioinspired ...

Heat and light get larger at the nanoscale

In a new study recently published in Nature Nanotechnology, researchers from Columbia Engineering, Cornell, and Stanford have demonstrated heat transfer can be made 100 times stronger than has been predicted, simply by bringing ...

Higher measurement accuracy opens new window to the quantum world

A team at HZB has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microKelvin in the thermal Hall effect. Previously, these temperature differences ...

Discovery of stress-induced emotional fever in fish

Fish react emotionally to stress, indicating a degree of consciousness, a groundbreaking new study by scientists at the University of Stirling's Institute of Aquaculture has found.

New method measures temperature within 3-D objects

University of Wisconsin-Madison engineers have made it possible to remotely determine the temperature beneath the surface of certain materials using a new technique they call depth thermography. The method may be useful in ...
