Nanocellulose‐Induced “Surface‐Lock” Engineering: Curbing the Dissolution of MnO2 for High‐Performance Zn–MnO2 Flexible Electrodes

open access: yesCarbon Energy, EarlyView.
The study designed the nanocellulose‐induced “surface‐locking” strategy to stabilize the interface between MnO2 and a carbon‐based substrate. The dissolution of MnO2 was prominently curbed by imparting C–O–Mn bonding and optimized wettability. Zn–MnO2 batteries were endowed with outstanding cyclic stability and improved capacity.

Dual‐Mode Thio‐MacMillan Organocatalysts: Stereoselective Diels–Alder Reactions or Sacrificial Self‐Cyclization to N‐Bridged Bicyclic Lactams

open access: yesChemistry – A European Journal, EarlyView.
The study of the Diels–Alder reaction of cinnamaldehyde and cyclopentadiene, catalyzed by chiral imidazolidine‐4‐thiones, led to the discovery of a highly regio‐ and stereoselective Michael‐addition and consecutive ring closure. Here, the imidazolidine‐4‐thione not only catalytically activates cinnamaldehyde but also participates as the nucleophile to ...

Photocatalytic Degradation of PFOA with Porous Lanthanoid Perovskites Nano Catalyst

open access: yesChemie Ingenieur Technik, EarlyView.
Photocatalytic degradation of PFOA was studied using nickel‐ and lanthanide‐doped perovskites under UV–VIS irradiation. Catalyst characterization confirmed successful doping, with Ni/NdMnO3 showing the highest photocatalytic efficiency. Degradation occurred via C–C bond cleavage, forming transformation products PFHpA and PFHxA.

Bayesian clustering of multivariate extremes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract The asymptotic dependence structure between multivariate extreme values is fully characterized by their projections on the unit simplex. Under mild conditions, the only constraint on the resulting distributions is that their marginal means must be equal, which results in a nonparametric model that can be difficult to use in applications ...
