Particle‐Level ZrO2 Atomic Layer Deposition Enables Fast‐Cycling and Long‐Life Graphite Cathodes for Dual‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A spatial location of atomic layer deposition (ALD)‐derived ZrO2 coatings is demonstrated to be a critical design parameter for stabilizing graphite cathodes in DIBs. Direct particle‐level ALD (PALD) screening of representative metal oxides identified ZrO2 as the coating that provides the most favorable balance of high‐rate capability and interfacial ...

Regioselective Photoredox Catalyzed Cycloadditions of Acyclic Carbonyl Ylides [PDF]

open access: yes
A photoredox catalyzed [3+2] dipolar cycloaddition between acyclic carbonyl ylides generated from -cyano epoxides and dipolarophiles is described. This method, influenced by anionic charge localization and temperature control, enabled the synthesis of ...

Rare‐Earth–Functionalized Carbon Dot Hydrogels as Mechanically Robust Antibacterial Wound Dressings

open access: yesAdvanced Healthcare Materials, EarlyView.
The schematic depicts a dynamically cross‐linked PVA hydrogel network in which reversible borate ester bonds and hydrogen‐bonding interactions integrate lanthanum‐doped carbon dots (La‐CDs) and dipotassium glycyrrhizinate (DPG) to form a mechanically robust, multifunctional matrix.

Evaluation of Retro-Aldol vs Retro-Carbonyl-Ene Mechanistic Pathways in a Complexity-Generating C–C Bond Fragmentation

open access: yes
We report an experimental and computational investigation of the likely mechanism of a cascade reaction. The reaction involves an intramolecular Diels–Alder reaction, followed by a C–C bond cleavage, to afford a complex bridged bicyclic product.
