Scientists from Johns Hopkins and Samsung have come up with a new thermoelectric material called CHESS that could change the game for cooling technologies. This nano-engineered innovation is twice as efficient as current options, which makes it ideal for solid-state refrigeration. With its potential for broader use, CHESS might help bring energy-efficient cooling to more applications, from electronics to food preservation.
