Human‐Guided Bayesian Optimization Enables High‐Throughput Laser Annealing of Mesoporous SiOx Anodes for Lithium‐Ion Batteries

Advanced Science, EarlyView.
An empirical‐aided active learning framework is developed to optimize high‐throughput laser‐induced photothermal annealing of silicon suboxide anodes. By integrating probabilistic machine learning with empirical domain knowledge, this approach achieves optimal electrochemical performance using limited experiments.

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction

Advanced Science, EarlyView.
Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Carbon‐Encapsulated Gemini Ionic Liquid as Advanced Bromine Hosts for High‐Performance Zn–Br2 Batteries

Angewandte Chemie, EarlyView.
Rapid self‐discharge limits the practical deployment of Zn–Br2 batteries. Herein, a gemini ionic liquid featuring dual bromine‐binding sites and an aromatic linker is confined within porous carbon electrodes. The ionic liquid simultaneously complexes bromine species and interacts strongly with the carbon matrix, enabling efficient bromine retention ...

Covalently Integrated Selenoviologen–N‐Heterocyclic Carbene–Pt Nanoparticles for Visible‐Light‐Driven Hydrogen Evolution

Advanced Science, EarlyView.
A covalently integrated single‐component photocatalyst is constructed by anchoring selenoviologen to platinum nanoparticles via robust N‐heterocyclic carbene ligands. The resulting Pt─C covalent bonds function dually as protective structural scaffolds and direct channels for ultrafast intramolecular electron transfer This precise interfacial ...

Synthesis of Indole-Based Derivatives Containing Ammonium Salts, Diamines and Aminoureas for Organocatalysis

Organics
Indole heterocycles have an established reactivity, and these compounds are H-bond donors via a peculiar non-basic NH. However, the indole core has been scarcely employed in organocatalysis, with only a few examples relevant to electrophilic halogenation

A practical electrodialysis model for accelerating system development

AIChE Journal, EarlyView.
Abstract Empirical optimization of electrodialysis (ED) is dependent on repetitive experiments with incremental adjustments, which is cost prohibitive at scale. While models can reduce the costs associated with optimization and scale‐up, existing ED models are limited in application to specific use cases and tend to be developed for the exploration of ...
