(Nanowerk News) Combining state-of-the-art realistic atomistic modelling and experiments, the paper describes how thermal conductivity of ultrathin silicon membranes is controlled to large extent by ...

In a recent experiment, to be published in Nature on Nov. 9, Dr. Matthias Meschke and professor Jukka Pekola, together with Dr. Wiebke Guichard, a coworker from French CNRS, investigated heat exchange ...

Technical ceramics are used in many applications where traditional materials such as steel or plastic are ineffective or unsuitable. For many of these applications, extreme hardness, wear resistance, ...

Thermoelectric effect is a phenomenon that utilizes temperature difference to achieve electrical transport, offering potential solutions to the energy and environmental challenges faced by humanity.

Engineers have flipped the picture of the standard polymer insulator, by fabricating thin polymer films that conduct heat -- an ability normally associated with metals. In experiments, they found the ...

Lab instrumentation has been selected from TecQuipment, a designer of thermal/fluids devices for use in higher education. Students study the three modes of heat transfer - conduction, convection and ...

Synthetic quartz may help reduce the carbon footprint of industries that produce things like glass, steel, and cement. In recent experiments, Federal University of Technology, Zurich, engineer ...

Thermal conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. The colliding particles, which include molecules, atoms and ...

You may have heard that some people are brave enough to walk across hot coals, but would you ever attempt to carry coals, or a whole fire, in your hands, for miles and miles? Cultures from around the ...
