Thermoelectric systems are a green and sustainable way to harvest energy from any form of heat that otherwise would be wasted. At the core of this energy conversion process is the so-called Seebeck effect, which describes ...
A team of biophysicists affiliated with several institutions in China has uncovered via experimentation the means by which early life might have been able to survive cosmic radiation. In their study, reported in the journal ...
Understanding the ionosphere high in the Earth's atmosphere is important due to its effects on communications systems, satellites and crucial chemical features including the ozone layer. New insights into the activity of ...
