Cascade Spirocyclization–Difunctionalization or Rearrangement of Bicyclobutyl-Tethered Aldehyde Hydrazones via Strain Release

Abstract A cascade spirocyclization–difunctionalization of bicyclobutyl-tethered aldehyde hydrazones with N-halosuccinimides was smoothly performed to access diverse halo-succinimide-containing diazaspiro[3.3]heptan-3-ones. Meanwhile, the three-component rearrangement of bicyclob...

Neutron Total Scattering Investigation of the Dissolution Mechanism of Chitotriose in Alkali/Urea Aqueous Solutions

Abstract Despite the promise of alkali/urea aqueous solutions as green solvents, the atomistic-scale mechanism of chitin dissolution remains elusive. In contrast to the ability to dissolve cellulose, the order of alkali effectiveness for dissolving chitin is potassium hydroxide (...

E3 Ubiquitin LigasePdSINA2D in Populus deltoides Positively Regulates ABA-Dependent StressTolerance through Ubiquitination of FREE1 in Poplar

Abstract Populus deltoides “Shalinyang” (PdS) displays reduced tolerance to abiotic stresses. SINA (seven in absentia) proteins, a subtype of E3 ubiquitin ligases, play crucial roles in regulating plant growth and responses to abiotic stresses. However, the characteristics and po...

Phosphonic AcidMolecular Regulation of Frenkel Defectsfor Suppressing Nonradiative Recombination in FAPbI3 Perovskites

Abstract Surface Frenkel defects are an important source of nonradiative carrier losses in formamidinium lead iodide (FAPbI3) perovskites; however, the microscopic mechanisms by which molecular geometry regulates defect-mediated excited-state dynamics remain poorly understood. He...
