A new composite phase change material composed of Na2SO4·10H2O and expanded graphite has been developed to regulate battery temperatures and mitigate thermal runaway risks. The material's dual-stage temperature control mechanism effectively manages LIB heat, reducing peak temperatures and delaying the onset of TR events.
Researchers at Ritsumeikan University propose a room-temperature defluorination method that uses visible light to break down PFAS and other fluorinated polymers into fluorine ions. The method achieved 100% defluorination of perfluorooctanesulfonate within 8 hours of light exposure.
Hydrated electrons play a significant role in various processes, and researchers have observed their effect on the water solution. The study reveals that the electron causes a 'water quake' or 'tsunami,' which is caused by sudden charge separation during its formation.

Aranet4 Home CO2 Monitor tracks ventilation quality in labs, classrooms, and conference rooms with long battery life and clear e-ink readouts.
Researchers used correlated wavefunction theory to simulate the bulk hydrated electron, finding a persistent tetrahedral cavity made up of four water molecules. The model provided stronger theoretical evidence for the cavity model, dismissing non-cavity structures in stable and metastable states.
Chemists at Martin-Luther-Universität Halle-Wittenberg have developed a new process that utilizes hydrated electrons to degrade dissolved pollutants. The process requires only sunlight and can be conducted outdoors with minimal equipment, offering a promising solution for water pollution remediation.
Researchers at Argonne National Laboratory have observed nanoparticle chains forming in situ for the first time, using a transmission electron microscope. The study demonstrates the potential of nanoparticles in energy-relevant technologies and could lead to new materials with unique properties.
