Biocoating
In article number 2107559, Edith Mathiowitz and co‐workers characterize the effects of nanoparticles (NPs) interaction with gut mucins. Mucins biocoating alters the surface charge, effective size, mucosal diffusion coefficient, and the extent of NPs aggregation. The implementation of this natural phenomenon may improve in vitro to in vivo correlation and alleviate long‐lasting controversies...
Rechargeable zinc‐ion batteries (ZIBs) with exceptional theoretical capacity have garnered significant interest in large‐scale electrochemical energy storage devices due to their low cost, abundant material, inherent safety, high specific energy, and ecofriendly nature. Metal carbides/nitrides, known as MXenes, have emerged as a large family of 2D transition metal carbides or carbonitrides with excellent...
A universal strategy is established for preparing the carbonaceous matrix‐based atomically distributed metal catalysts M‐BPC (M=Ni, Co, Fe, Cu, and Mn, and biomass‐derived porous carbon (BPC)) by one‐step pyrolysis of mixed metal salts and biomass alfalfa. The optimized Ni‐BPC has dual‐atom Ni(II)2N4(µ2‐N)2 moieties, which are chemically anchored on the alfalfa‐derived developed porous N‐doped carbon...
Tissue bacterial infections are a major pathological factor in many diseases.

Commercialized lithium cobalt oxide (LCO) only shows a relatively low capacity of ≈175 mAh g−1 despite a high theoretical capacity of ≈274 mAh g−1. As an effective and direct strategy, increasing its charge cutoff voltage can, in principle, escalate the capacity, which is however precluded by the irreversible phase transition, oxygen loss, and severe side reactions with electrolytes normally. Herein,...
Electrochemical reduction of oxygen plays a critical role in emerging electrochemical energy technologies.
