Recent Advances in Wide‐Bandgap Perovskite Solar Cells

Advanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

The Importance of Metal Ion Impurity Bands in the Photoluminescence of Halide Double Perovskites

Advanced Optical Materials, EarlyView.
Many publications have associated emission spectral features of double perovskite halides in the region at 460–470 nm with “pristine” materials. This leads to not only false observations but also incorrect conclusions concerning the transformation of dark into bright excitons or boosting self‐trapped exciton emission.

Double‐Sided Control of Product Type Preference in the Visible‐Light Initiated Reaction of 1,3‐Dicarbonyl Compounds with Alkenes

Advanced Synthesis &Catalysis, EarlyView.
Abstract The demonstrated light‐initiated addition of radicals formed on an active methylene group to styrene derivatives exhibits a product selectivity influenced by the presence of a protic solvent. Under protic conditions, the predominant products are branched compounds with the alkene moiety attached to the methylene group.

Tunable Preparation of β‐Substituted Alkenoate Esters via Radical Alkenylation of C(sp3)–H Bonds with Allenoates

Advanced Synthesis &Catalysis, EarlyView.
Abstract A photocatalytic strategy for the radical alkenylation of aliphatic C(sp3)–H bonds with 2,3‐allenoate esters is described. The protocol takes place upon irradiation of the reaction mixture in the presence of the decatungstate anion, which triggers C−H cleavage in the chosen aliphatic substrates.

Dual Charge Transfer Mechanisms in Intimately Bonded S‐scheme Heterojunction Photocatalyst with Expeditious Activity toward Environmental Remediation

Advanced Sustainable Systems, EarlyView.
A novel MBOdCN S‐scheme heterojunction photocatalyst is fabricated using pristine Mg‐Bi2O3 and grayish g‐C3N4, where dynamic dual charge migration paths occur to accelerate exciton dissociation. This composite catalyst realizes high degradation efficiency of up to 99.56% of oxytetracycline (OTC) removal under optimized conditions. The material exhibits

Ion mobility-tandem mass spectrometry of mucin-type O-glycans

Nature Communications
The dense O-glycosylation of mucins plays an important role in the defensive properties of the mucus hydrogel. Aberrant glycosylation is often correlated with inflammation and pathology such as COPD, cancer, and Crohn’s disease.
