Enhancement in the yield and properties of cellulose nanocrystals by two- batch addition of ammonium persulfate

This study demonstrates that a two-batch addition of ammonium persulfate during cellulose nanocrystal isolation significantly enhances yield, aspect ratio, and thermal stability while reducing polydispersity, ultimately leading to superior mechanical properties in polyvinyl alcohol/CNC composite films compared to the traditional single-batch method.

Chalcogenide perovskites BaTi(OS)3 with band gap in the optimal Shockley-Queisser range

This study demonstrates that synthesizing chalcogenide perovskite BaTi(O₁₋ₓSₓ)₃ via CS₂ sulfidation of BaTiO₃ at elevated temperatures induces a tetragonal-to-hexagonal structural transition and reduces the band gap to the optimal Shockley-Queisser range of 1.47 eV.
