Illuminating mechanochemical reactions by combining real-time fluorescence emission monitoring and periodic time-dependent density-functional calculations

, 2021
We provide a proof-of-principle demonstration of the first dual-spectroscopic method for direct and real-time observation of mechanochemical reactions by ball milling, supported by high-level molecular and periodic density-functional theory (DFT ...

Microstructural deformation in the clinching process

Journal of Advanced Joining Processes, 2021
Need – There is a need to better understand the shear and plastic deformation that arises during clinch joint formation. Since microstructural texture preserves a history of deformation, grain structure has the potential to reveal the role of the ...

Wittig olefination “baking powder”: a hexameric halogen-bonded phosphonium salt cage for encapsulation and mechanochemical transformation of small-molecule carbonyl compounds

, 2021
We report a hexameric supramolecular cage assembled from the components of a Wittig-type phosphonium salt, held together by charge-assisted R-Br· · ·Br-· · ·Br-R halogen bonds. The cage reliably encapsulates small polar molecules, including aldehydes and

Iron-Catalyzed Asymmetric Csp3–H/Csp3–H Coupling：Improve the Chirality Induction by Mechanochemical Liquid-Assisted Grinding

, 2023
The iron-catalyzed asymmetric oxidative coupling is a challenging transformation that is typically restricted to naphthol substrates (Csp2–H) with carefully designed chiral ligands.

Symmetry Breaking and Epithelial Cell Extrusion

Cells, 2020
Cell extrusion is a striking morphological event found in epithelia and endothelia. It is distinguished by two symmetry-breaking events: a loss of planar symmetry, as cells are extruded in either apical or basal directions; and loss of mechanochemical ...
