"Physics Principle Reversed: Like-Charged Particles Attract, Opposites Repel"

A study from Oxford University has challenged a fundamental principle of physics by demonstrating that similarly charged particles in solution can attract each other, with the effect varying based on the solvent. This overturns the long-held belief that like charges repel. The research has implications for various scientific processes, including self-assembly and crystallization, and suggests a need to re-evaluate our understanding of electromagnetic forces. The study also provides evidence for the ability to probe properties of interfacial electrical potential due to the solvent, which were previously thought immeasurable.

Unveiling Ion Solvation: Atom-by-Atom Recordings in Helium Droplets

Researchers have observed the primary steps of ion solvation in helium droplets using a combination of experimental and computational techniques. The study provides insights into the solvation dynamics of ions in a unique nanomatrix of superfluid helium, shedding light on the fundamental processes involved in solvation. The findings have implications for understanding solvation phenomena in other systems and could contribute to the development of new materials and technologies.
