Scientists have developed a new ionocaloric cooling method that uses salt and phase change principles to cool efficiently and environmentally friendly, potentially replacing traditional refrigerants with high global warming potential.
Scientists at SLAC have used ultrafast laser heating and X-ray scattering to superheat gold to 19,000 kelvins—over 14 times its melting point—without melting, challenging long-standing thermodynamic limits and suggesting that the entropy catastrophe can be avoided with rapid heating, opening new avenues in material science and extreme condition modeling.
Researchers observed a superconductor behavior that defies current physics understanding, as quantum fluctuations unexpectedly ceased at a certain electron density in a superconducting experiment using tungsten ditelluride. This phenomenon challenges existing theories and requires new understanding of superconducting quantum phase transitions, presenting an intriguing puzzle for physicists to solve.
