Trans‐A2B2‐Type Metalloporphyrin‐Based Donor–Acceptor Covalent Organic Frameworks for Efficient Photocatalytic CO2 Cycloaddition to Aziridines

open access: yesAdvanced Science, EarlyView.
Two novel trans‐A2B2‐type porphyrin‐based D‐A type covalent organic frameworks (COFs), including metal‐free m‐DBPA‐COF and metallized m‐NiDBPA‐COF, have been successfully synthesized and under visible light‐assisted and mild conditions (1 atm CO2 with no heating required), m‐NiDBPA‐COF exhibits remarkable photocatalytic performance, achieving a ...

An Advanced High‐Performance Ultrafast Ammonium‐Ion Aqueous Battery Based on Dual‐Metal Redox Open Framework Molecular Magnet

open access: yesAdvanced Science, EarlyView.
The Prussian Blue Analogue molecular magnet KMnFeHCF is demonstrated as a high‐performance cathode for ultra‐fast aqueous ammonium‐ion batteries. A full cell using KMnFeHCF and graphite delivers ~71 mAh g−1 at 1.25 A g−1 and ~51 mAh g−1 at 2.2 A g−1, retaining 50% capacity after 1850 cycles. Its scalability, cycling stability, and low cost offer strong

Determination of the Exchange Current Density at Lithium │ Polymer Electrolyte Interfaces

open access: yesAdvanced Science, EarlyView.
This work presents a comprehensively validated method to determine the exchange current density (j0) at the interface of lithium metal and polymer electrolytes by combining electrochemical impedance spectroscopy with Bayesian inference and distribution of relaxation times analyses to successfully deconvolute solid electrolyte interphase and charge ...

Principles for Rigorous Design and Application of Synthetic Microbial Communities

open access: yesAdvanced Science, EarlyView.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Atomistic Insights into the Electrochemical Oxygen Evolution Activity of Hollandite IrO2 Surfaces

open access: yesAdvanced Science, EarlyView.
Lattice distortions at tunnel‐structured hollandite IrO2 surfaces reshape Ir‐O bonding: they weaken the σ‐bond contribution in the Ir‐*OH bond while enhancing the π contribution of the Ir‐*O bond. This orbital reorganization in hollandite surfaces stabilizes *O, facilitates the *OH → O step, and lowers the oxygen‐evolution reaction overpotential ...

Gecko‐Inspired Adhesive for Robotic Grippers with Excellent Ultra‐Low‐Temperature Adhesion Performance

open access: yesAdvanced Science, EarlyView.
Phenyl and vinyl groups are used to modify conventional polydimethylsiloxane (PDMS) to yield poly(methylphenylvinylsiloxane) (PMPVS). PMPVS‐based gecko‐inspired arrays with mushroom tips exhibit superior adhesion strength of 36.7 kPa even at −80 °C, which enhances by 5143% compared to PDMS‐based arrays (0.7 kPa at −70 °C).
