Intermolecular Enantioselective Nickel‐Catalyzed Arylation of Un‐Activated C(sp3)─H Bond

open access: yesAngewandte Chemie International Edition, EarlyView.
Ni: a new solution for asymmetric C(sp3)─H activation. The stereoselective synthesis of all‐carbon quaternary stereogenic centres is achieved via enantioselective C(sp3)─H arylation using a Ni‐BINOL‐derived catalyst. Rational catalytic cycle design uncovers a new reaction pathway that can efficiently induce chiral information during the stereoselective

Cluster dynamics modeling of hydrogen retention and desorption in tungsten with saturation and multi-trapping effect of sinks

open access: yesNuclear Fusion
Hydrogen (H) retention and desorption in tungsten (W)-based plasma-facing materials are still not well understood, largely due to the limitations of ex-situ observations in experimental detection methods like thermal desorption spectroscopy (TDS).

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...

Hydrogel Embedding of Mesenchymal Stem Cells Supports Extracellular Vesicle Production

open access: yesBiotechnology and Bioengineering, EarlyView.
This study investigates the effects of 3D culture conditions on extracellular vesicle (EV) production by mesenchymal stem cells (MSCs) in a gelatin‐based hydrogel matrix (GelMA). The EVs from both conditions were found to have similar morphological, molecular, and functional properties, but 3D cultures produced more total EVs per volume.
