Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Photoinduced Interfacial Electronic Modulation in Fe2O3‐BiVO4 Heterostructures for Enhanced Photo‐Assisted Zn‐Air Batteries

Advanced Functional Materials, EarlyView.
Light irradiation activates the Fe2O3‐BiVO4 heterostructure, enabling efficient solar‐electrochemical coupling in zinc‐air batteries. The built‐in electric field drives directional charge separation, guiding photoelectrons toward oxygen reduction sites and accumulating holes for oxygen evolution, thereby reducing polarization and enhancing discharge ...

Polymer Side‐Chain Electronic Effects Regulating Solvation Sheath for Low‐Temperature and High‐Voltage Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
This work reveals the influence of polymer side‐chain electronic effects on the Li+ solvation sheath in gel polymer electrolytes. Electron‐donating side chains induce the strong Li+ coordination and FDMA‐dominated solvation, impeding Li+ desolvation, whereas electron‐withdrawing side chains weaken Li+ coordination, facilitating anion‐rich solvation and

Unique Role of Microstructure of a Bioimplant Zinc Alloy and Protein Content of Simulated Body Fluid in Corrosion and Fracture

Advanced Functional Materials, EarlyView.
BSA addition to physiological solutions enhances resistance of a Zn alloy to stress corrosion cracking (SCC) but reduces its corrosion resistance. Extended surface characterization explains the contrasting influences on corrosion and SCC. Unexpectedly, the alloy suffers transgranular SCC (TGSCC), despite extensive grain boundary precipitation. Thorough

The stability and redox mechanisms of Ni-rich NMC cathodes: Insights from first-principles many-body calculations [PDF]

Ni-rich LiNi_aMn_bCo_cO_2 (NMC) cathodes undergo a series of degradation reactions, a prominent one being oxygen loss from the surface of the NMC particles, this process being more pronounced as Ni content is increased and at high voltages.
