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 ...

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 ...

Materials chemists tap body heat to power 'smart garments'

Many wearable biosensors, data transmitters and similar tech advances for personalized health monitoring have now been "creatively miniaturized," says materials chemist Trisha Andrew at the University of Massachusetts Amherst, ...

Thermal gradients shown to enhance spin transport in graphene

Scientists of the ICN2 Physics and Engineering of Nanodevices Group, led by ICREA Prof. Sergio O. Valenzuela, have contributed to the literature on spin caloritronics with a focus on the effect of thermal gradients on spins ...

Prescribed burning may benefit rattlesnakes

A forest at first appears devastated after a fire, devoid of color. Ash and smoky plant remains cover the forest floor. In a few short weeks, however, shrubs and forbs will poke through the ash, taking advantage of the nitrogen ...

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 ...

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.

Intense lasers cook up complex, self-assembled nanomaterials

Nanoscale materials feature extraordinary, billionth-of-a-meter qualities that transform everything from energy generation to data storage. But while a nanostructured solar cell may be fantastically efficient, that precision ...

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 ...
