Digital to analog converter bridges the gap between internet and electronic hardware. Researchers at the George Washington University and University of California, Los Angeles, have developed and demonstrated for the first time a photonic digital to analog converter without leaving the optical domain. Such novel converters can advance next-generation data processing hardware with high relevance for datacenters, 6G networks, artificial intelligence and more.

Current optical networks, through which most of the world’s data is transmitted, as well as many sensors, require a digital-to-analog conversion, which links digital systems synergistically to analog components...

A new type of rocket thruster that could take humankind to Mars and beyond has been proposed by a physicist at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL).

The device would apply magnetic fields to cause particles of plasma, electrically charged gas also known as the fourth state of matter, to shoot out the back of a rocket and, because of the conservation of momentum, propel the craft forward. Current space-proven plasma thrusters use electric fields to propel the particles.

The new concept would accelerate the particles using magnetic reconnection, a process found throughout the universe, incl...

Researchers in WMG at the University of Warwick, in collaboration with Imperial College London, have found a way to enhance hybrid flow batteries and their commercial use. The new approach can store electricity in these batteries for very long durations for about a fifth the price of current technologies, with minimal location restraints and zero emissions.

The researchers enhanced three hybrid flow cells using nitrogen doped graphene (exposed to nitrogen plasma) in a binder-free electrophoresis technique (EPD).

Wind and solar power are increasingly popular sources for renewable energy. Unfortunately, intermittency issues keep them from connecting widely to the National grid...

Researchers have discovered a short-lived form of the famous Higgs boson — subject of a groundbreaking search at the Large Hadron Collider — within an iron-based superconductor. This Higgs mode can be accessed and controlled by laser light flashing on the superconductor at trillions of pulses per second.

There was the title of a 1993 book by Nobel laureate Leon Lederman that dubbed the Higgs “The God Particle.” There was the search for the Higgs particle that launched after 2009’s first collisions inside the Large Hadron Collider in Europe...
