New understanding of electromagnetism could enable 'antennas on a chip'
A team of researchers from the University of Cambridge have unravelled one of the mysteries of electromagnetism, which could enable the design of antennas small enough to be integrated into an electronic ...
'Phonon tunneling' explains heat flow across nanometer-wide gaps, study finds
Conduction and thermal radiation are two ways in which heat is transferred from one object to another: Conduction is the process by which heat flows between objects in physical contact, such as a pot of tea ...
