Divergent Single‐Oxygen Transmutation of Furans

ABSTRACT Despite the prevalence of furans in organic chemistry, their direct conversion into diverse heterocycles via oxygen transmutation remains a formidable challenge. This limitation is primarily attributed to the robust endocyclic C—O bonds, its aromaticity, and the lack of...

Monomer-biased manufacture of industrial-scale colloidal photonic films

Complex functions in nature arise from the ordered assembly of simple building blocks. Transformation of colloidal aggregates into industrial-scale photonic crystals under rapid ambient conditions remains challenging owing to high energy barriers and limited assembly control. In...

Scaling analysis of the pressure distribution in shock wave/boundary layer interactions on convex surfaces with extended free-interaction theory

Predicting the pressure distribution in shock wave/boundary layer interaction (SWBLI) over convex surfaces is critical for hypersonic vehicle design, yet a unified theoretical model remains absent. This work extends the classical free-interaction theory by introducing two dimensi...
