Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

open access: yesAngewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Bioassay-guided fractionation to isolate compounds of onion (Allium cepa L.) affecting bone resorption [PDF]

open access: yes, 2004
In this work a hydrophilic ethanolic extract of onion (Allium cepa L.) devoid of flavonoids was found to inhibit significantly bone resorption in vitro and in vivo, whereas the flavonoids, claimed to posses phytoestrogen-like properties, were devoid of ...

Harnessing Li‐Ion Binding Energy for Solvation‐Guided Electrolyte Additive Design and Robust Solid Electrolyte Interphase Reinforcement

open access: yesAdvanced Science, EarlyView.
A solvation‐guided design strategy for electrolyte additives is established, identifying Li‐ion binding energy as a crucial determinant for effective interface reinforcement. ABSTRACT The rational design of electrolyte systems is essential for stabilizing the electrode−electrolyte interface to enhance the electrochemical performance of lithium‐ion ...

Sticker Valence Governs Chain Collapse and Liquid‐Liquid Phase Separation in Peptide‐Inspired Associative Polymers

open access: yesAdvanced Science, EarlyView.
Peptide‐inspired associative polymers with arginine‐like guanidinium stickers and lysine‐like ammonium spacers undergo chain collapse and liquid‐liquid phase separation induced by reversible sticker associations. Sticker valence and tunable association strength jointly control the phase behavior, chain conformation, and interfacial cohesion of these ...

Electro‐Organic Synthesis at a Stable Oil/Water/Solid Three‐Phase Interface Reactor

open access: yesAngewandte Chemie, EarlyView.
A porous membrane electrode (PME) reactor is developed to promote oil/water/solid three‐phase interfacial contact for electro‐organic synthesis. By promoting the formation of an oil/water interfacial region within or near an amphiphilic catalytic layer, the reactor enables efficient conversion of water‐insoluble organic reactants in aqueous ...

Overcoming Drug Resistance by Paclitaxel Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
In the murine triple‐negative breast cancer (TNBC) model, chemotherapy effectively increases tumor neoantigen burden (TNB). Here, the study constructs a liposomal nanovaccine using antigens derived from in vitro chemotherapy‐treated paclitaxel‐resistant TNBC 4T1 cells.

Chiral Fjord‐Edged Nanographenes Constructed by Allylic‐Migration‐Mediated Cyclization

open access: yesAngewandte Chemie, EarlyView.
A novel allylic‐migration‐mediated cyclization strategy enables the construction of two fjord‐edged nanographenes without steric blocking groups. The resulting non‐planar molecules exhibit remarkable chiroptical properties, with an absorption dissymmetry factor surpassing those of pristine [5]helicene and previously reported fjord‐edged nanographenes ...
