The effective control of heat transfer is of great significance to improve energy efficiency. Thermal diode is one of the key elements for heat flow controlling. Similar to the current rectification ...

(Nanowerk News) You can feel it on your laptop and mobile phone. It’s behind your refrigerator and office copy machine. While heat is desirable for appliances like a coffee maker, it can jeopardize ...

It is one of the humans’ desired goals that we want to precisely control the heat transport as the level as that we can control the electrical current. However, a high-performance thermal rectifier or ...

There’s no escaping the insidious effects of heat in microchips. But there may now be a way of controlling it. Wataru Kobayashi at Waseda University in Japan and a few friends have built a rectifier ...

We’re all familiar with semiconductor diodes, whose function is to allow electricity to easily flow in one direction and impede its progress in the other. A thermal diode performs a similar gating ...

Researchers are proposing a new technology that controls the flow of heat the way electronic devices control electrical current. Triangular graphene nanoribbons (a) are proposed as a new thermal ...

(Nanowerk News) Recently, the possibility of using phase-transition materials for near-field radiative heat transfer (NFRHT) has garnered increased attention. Of particular interest has been vanadium ...

This is the last in a series of three articles on thermal diodes. The previous two articles of our 'thermal diode' series, How to Measure Temperature in Integrated Systems and The ‘Thermal Diode’…A ...

Electronic systems don't work well in heat – which is a problem, because apart from a few exceptions, heat is a normal byproduct of electricity. Researchers have now developed a thermal diode: a ...

Everyone loves a full-wave bridge rectifier, but there’s no denying that they aren’t 100% efficient due to the diode voltage drop. Which isn’t to say that with some effort we ...
