Full duplex seems easy. In fact, so easy that it was possible with the first basic telephones. There was one loop between each phone and the central office, and that one loop carried conversation... » read more

Power/Performance Bits: April 19


Ferroelectric non-volatile memory Scientists from the Moscow Institute of Physics and Technology (MIPT), the University of Nebraska, and the University of Lausanne in Switzerland succeeded in growing ultra-thin (2.5-nanometer) ferroelectric films based on hafnium oxide that could potentially be used to develop non-volatile memory elements called ferroelectric tunnel junctions. The film was g... » read more
