Simultaneous Construction of Hydrophobic Environment and Optimized Ion Channels in V2O5 for Zinc Ion Batteries

Carbon Energy, EarlyView.
With the preinsertion of hexamethylenebisammonium (HMA2+), the thermodynamic stability of V2O5 is improved, and the kinetics of electrochemical reaction are enhanced, benefiting from the pillar effect, hydrophobicity, and electrostatic shielding of HMA2+.

Machine Learning Paradigm for Advanced Battery Electrolyte Development

Carbon Energy, EarlyView.
Electrolyte materials determine ion transport kinetics within the bulk and interphases, ultimately influencing the performance of battery systems. As data‐driven paradigms increasingly reshape materials discovery, this review provides an application‐oriented exploration of the intersection between machine learning and electrolyte science. By evaluating

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Decoupling Redox Potentials and Excited State Energies in Substituted Chromium(III) Chromophores

Chemistry – A European Journal, EarlyView.
Redox and excited state properties of organic and precious metal CT photocatalysts are strongly entangled. In contrast, redox potentials of polypyridine chromium(III) complexes, that feature purely metal‐centered SF states, are selectively tuned by incremental substituent effects of the CF3 group, while excited state energies and lifetimes remain ...

Performance Analysis of OTFS Framework Over Wideband Time-Varying Channels

IEEE Open Journal of the Communications Society
Orthogonal Time Frequency Space (OTFS) modulation has garnered significant attention for its robustness in high-mobility communication scenarios. Existing research predominantly focuses on narrowband time-varying channels, where Doppler effects manifest ...

Mild N‑Arylation of Sulfoximines With (Hetero)aryl Chlorides Enabled by α‐Methylnaphthyl‐tBuBrettPhos Palladium Triflate

Chemistry – A European Journal, EarlyView.
A readily accessible, air‐ and moisture‐stable palladium precatalyst, [Pd(1‐MeNAP)(tBuBrettPhos)]OTf, enables the direct N‐arylation of NH‐sulfoximines with (hetero)aryl chlorides under exceptionally mild conditions ideal for late‐stage diversification of drug‐like scaffolds.
