Breakthrough Cryogenic Analysis Reveals True Nature of Battery Interfaces

Scientists have developed a cryogenic XPS technique that preserves battery interfaces in their pristine state. The method reveals a strong correlation between inorganic-rich SEI content and battery performance across multiple electrolyte formulations.

Revolutionary Cryogenic Technique Preserves Battery Interface Chemistry

Researchers at Stanford University have developed a breakthrough cryogenic X-ray photoelectron spectroscopy (cryo-XPS) method that maintains battery interfaces in their pristine state, according to recent reports published in Nature. The technique reportedly overcomes long-standing limitations of conventional room-temperature XPS analysis, which sources indicate can cause irreversible chemical changes and species volatilization under ultra-high vacuum conditions.

London Air Quality Shows Dramatic Improvement Following ULEZ Implementation, Study Reveals

London has experienced substantial reductions in harmful nitrogen pollutants since the Ultra Low Emission Zone launched in 2019, according to new research. The study found nitrogen dioxide levels dropped by nearly 20% within three months of implementation. Despite these gains, scientists warn that air pollution still exceeds World Health Organization guidelines.

Significant Pollution Reductions Documented

London’s air pollution has seen dramatic improvements following the introduction of the Ultra Low Emission Zone (ULEZ), according to a comprehensive study led by the University of Birmingham. The research, which analyzed data from 124 monitoring sites across the capital, indicates that harmful nitrogen pollutants have dropped substantially both within the zone and in surrounding areas.
