Heating

A team from the University of Illinois and UC Berkeley has demonstrated a new cooling method that sucks heat out of electronics so efficiently that it allows designers to run 7.4 times more power through a given volume than conventional heat sinks.

Although a completely flat-surfaced wheel would be aerodynamic, it would also be hard to keep cool – especially during the braking process. An experimental new wheel rim, however, has cooling vents that open as needed … and they're activated by heat.

Heat is a major hurdle for electronic devices. Scientists have now found that nanowires made of a certain isotope of silicon can conduct heat 150 percent better than regular silicon, potentially leading to drastically cooler computer chips.

A specific cellular stress response involving heat shock proteins has been found to reverse the build-up of the toxic proteins linked to dementia. Future research will now look for a way to therapeutically trigger this mechanism.

Inspired by seashells, scientists at Sandia National Labs have engineered a versatile new material that’s incredibly inexpensive, strong, lightweight, and heat resistant. The material could find use in shielding for spacecraft or fusion facilities.

MIT says its new thermophotovoltaic heat engine can harvest more energy from heat than the average steam turbine, at a fraction of the cost and using no moving parts. Huge implications for future power stations, as well as grid-level energy storage.

Researchers in Japan have shown that a common material is excellent at storing and releasing heat, which could be useful for recycling industrial waste heat. The material exchanges water with the air, allowing it to quickly absorb or release heat.

While antibiotics are very effective at treating infected wounds, they should definitely be used sparingly. An experimental new bandage was designed with this fact in mind, as it only dispenses medication when it detects the heat of an infection.

Robots and other automated systems have always had trouble visually gauging the 3D shape of transparent objects, like those made of glass. A new system addresses that problem, by using a laser to quickly heat such items.

Researchers at Oxford have developed a new smart window coating that can be tuned on the fly to emit or reflect heat from the Sun in different amounts, reducing the energy costs of heating and cooling by up to a third.

Heat stroke is one of those things that can really sneak up on a person, potentially resulting in death if not quickly rectified. A new smartwatch-based system is designed to help, by warning its wearer before it's too late.

We've already heard about hoses that get wrapped around existing hot water pipes, using heat radiated from the pipe to heat water inside the hose. A new wrap-around device, however, uses that same pipe-heat to generate electricity.
