A Structurally Simple Polymer Donor Enables High-Efficiency Organic Solar Cells with Minimal Energy Losses.

Energy loss (Eloss) between optical energy gap (Eg) and open-circuit voltage (eVoc) sets efficiency upper limits for organic solar cells (OSCs). Nevertheless, further breaking the limit of Eloss in OSCs is challenging, especially via structurally simple materials in binary OSCs. Herein, a structurally simple non-halogenated polymer donor, namely PBDCT, is developed for realizing high-efficiency OSCs with record-breaking Eloss.

Identification and mechanism analysis of biomarkers related to butyrate metabolism in COVID-19 patients.

Photocatalyzed Three-Component Difluoroalkyl-Halogenation of Electron-Deficient Alkenes via a Halogen α-Nucleophilic Addition.

Here,we disclose a halogen α-nucleophilic addition via photocatalytic oxidation of the in-situ generated α-carbonyl radical of amides or esters to corresponding α-carbonyl cation. The α-carbon radical is generated by the β-addition of difluoroalkyl radical, formed by the photocatalytic reduction of BrCF2CO2R, to the α,β-unsaturated amides/esters. This umpolung strategy enables an efficient three-component difluoroalkyl-halogenation of α,β-unsaturated amides or esters with BrCF2CO2R and Cl/F-nucleophiles to produce diverse biologically important CF2-containing α-halo-1,5-dicarboxylic derivatives under mild conditions.

Biomimetic Localized Gel Electrolyte for Practical Zinc Anode.

Incompatible electrode/electrolyte interface often leads to dendrite growth, parasitic reactions and corrosion, posing significant challenges to the application of Zn anodes. Herein, we introduce a biomimetic antifreeze protein localized gel electrolyte (ALGE) with multifunctional capabilities to address these issues by combining electrolyte modification with interface optimization. ALGE modifies the Zn2+ solvation structure and the hydrogen-bond network adjacent to zinc anode, effectively suppressing hydrogen evolution.

Overcoming three-dimensional challenges through objective decomposition and virtual-digital design: A multidisciplinary case on hypodontia treatment.

A 15-year-old female sought multidisciplinary treatment for hypodontia, three-dimensional problems, deep overbite, multiple occlusal interferences, and collapse of the occlusion.
