(Phys.org)—While investigating how efficiently the brain can learn new information, physicists have found that, at the neuronal level, learning efficiency is ultimately limited by the laws of ...

The thermodynamic cycle followed by the engine is known as the Carnot cycle. In an ideal case, this process would be perfectly reversible and the Carnot engine would have maximum efficiency. In ...

(Nanowerk News) Harnessing quantum states that avoid thermalization enables energy harvesters to surpass traditional thermodynamic limits such as Carnot efficiency, report researchers from Japan. The ...

Information processing requires a lot of energy. Energy-saving computer systems could make computing more efficient, but the efficiency of these systems can't be increased indefinitely, as physicists ...

Researchers at the Lawrence Berkeley National Laboratory have developed a design and training framework ...

Physicists have created a device that has experimentally exceeded the conventional second law of thermodynamics. The device is an information engine, which converts information into work, and it is ...

An American research team developed the new formula by applying to bifacial cells the Shockley-Queisser triangle, which is used to calculate the maximum theoretical efficiency of a monofacial solar ...
