The effect of boron content on the structure and dielectric properties of alkali-free boroaluminosilicate glass

This study systematically investigates the impact of varying B₂O₃ content (6–14 mol%) on the structure and properties of alkali-free boroaluminosilicate glass, revealing that a composition with 12 mol% B₂O₃ optimizes the network structure to achieve a minimum dielectric constant of 4.47 at 10 GHz and a thermal expansion coefficient of 4.17×10⁻⁶/°C, making it ideal for 5G/6G communication applications.

Mn-Co-Ce composite oxides for the low-temperature catalytic oxidation of formaldehyde

This study demonstrates that Mn-Co-Ce composite oxide catalysts, specifically the Mn3.5Co1Ce1 variant synthesized via a citric acid sol-gel method, achieve highly efficient low-temperature formaldehyde oxidation and mineralization through a synergistic effect of spinel solid solution formation, hierarchical porosity, and abundant surface oxygen vacancies.

Conserved catalytic motifs encode enzyme-like supramolecular peptide assemblies

This study demonstrates that conserved catalytic motifs derived from natural enzymes can spontaneously self-assemble into highly active supramolecular peptide fibrils that recapitulate enzymatic function, proving that complex catalytic activity can emerge from simple peptide architectures independent of the original globular protein fold.

Ultraviolet Persistent Luminescence in Purely Organic Systems

This study reports a "hot-exciton" strategy utilizing indolocarbazole derivatives to achieve room-temperature ultraviolet persistent luminescence in purely organic systems by enabling reverse intersystem crossing through a high-lying triplet state, thereby overcoming the spectral limitations of conventional metal-free emitters.
