Merging Pyrrole with Boron into Versatile Di(2‐pyrryl)borane Building Blocks: π‐Extension, Polymerization, and Coordination

Angewandte Chemie, EarlyView.
The synthesis of di(2‐pyrryl)boranes, including the previously elusive unprotected N–H derivative, has been achieved that serve as versatile building blocks for π‐extended tetrahetarene boranes, a poly(dipyrrole borane), and a zirconium(IV) complex. The new π‐conjugated boranes are efficient blue‐light emitters, due to a twisted intramolecular charge ...

Toward a Rational Design of Conjugated Copolymers with Oxygenated Side Chains for Boosting Thermoelectric Properties

Advanced Energy Materials, EarlyView.
The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...

From Plastic Waste to Pharmaceutical Precursors: PET Upcycling Through Ruthenium Catalyzed Semi‐Hydrogenation

Angewandte Chemie, EarlyView.
We present a new catalytic process that converts real‐life PET waste into ethyl 4‐hydroxymethylbenzoate (EHMB), which serves as a valuable intermediate for the synthesis of pharmaceuticals, an insecticide, and a novel polyester. Abstract We report here the upcycling of PET (polyethylene terephthalate) waste via semihydrogenation to make ethyl 4 ...

Electrodialysis of LiPF6 in Aqueous Solution for Wastewater Treatment in Hydrometallurgical Recycling of Lithium‐Ion Batteries

Advanced Energy and Sustainability Research, EarlyView.
Hydrometallurgical recycling of lithium‐ion batteries produces wastewater containing PF6− and Li+, which must be removed and recovered, respectively. This study pioneers electrodialysis using anion exchange membrane and cation exchange membrane to separate PF6− and Li+.

Cellpose+, a Morphological Analysis Tool for Feature Extraction of Stained Cell Images

Advanced Intelligent Discovery, EarlyView.
We introduce Cellpose plus, a morphological and geometrical analysis tool for feature extraction of stained cell images built over Cellpose, a state‐of‐the‐art cell segmentation framework. We also introduce a dataset of DAPI and FITC stained cells to which our new method is applied.
