Congratulations to Dr. Cheng-Wei Lin and alumna Dr. Xueying Chang for their recent Account on aniline oligomers, showing how their well-defined molecular structures enable precise control over doping behavior, crystal growth, and functional properties. By treating aniline oligomers as tunable small molecules, the study demonstrates new insights into redox chemistry, nanostructure formation, surface functionalization, and applications ranging from membranes to long-cycle-life supercapacitor electrodes, revealing advantages that surpass traditional conducting polymers.

Congratulations to our visiting scholar, Hung-Yi Huang, on his new publication on full-polymer electrochemical deionization, which uses dopant-engineered polypyrrole electrodes and EQCM analysis to enable tunable, membrane-free removal of oxyanions through electrochemically controlled ion exchange.

Michelle Xie, Joo Wan Kim, and Cheng-Wei have published “Heterophase Reduction of the Fully Oxidized Aniline Tetramer” in ACS Materials Letters. Using phenyl-capped aniline tetramer (TANI) as a model of polyaniline (PANI), the study explores the heterophase reductions of the pernigraniline base, offering new insights into conductive polymer chemistry.

Zhiyin (Tara) Yang’s research, “Ultra-fast Sodium-Ion Batteries Based on Vanadium Oxide and Laser-Scribed Graphene Electrodes,” has been published in Chemistry of Materials. This work introduces a novel synthetic strategy for creating vanadium oxide laser-scribed graphene (VOLG) electrodes as highly functional anode materials for sodium-ion batteries.

Kaner group member Cheng-Wei has published the article “A Reflection on ‘Highly Dispersible Polypyrrole Nanospheres for Advanced Nanocomposite Ultrafiltration Membranes’” in Materials Horizons. The piece reviews the impacts of conjugated polymer-based water filtration membranes and highlights their significance in shaping subsequent research within the group.

Ailun (Helen) Huang and Zhiyin (Tara) Yang’s work, “A Nanoengineered Vanadium Oxide Composite as a High-Performance Anode for Aqueous Li-Ion Hybrid Batteries,” has been published in Nanoscale Horizons. The study introduces a novel synthetic strategy to fabricate a pseudocapacitive V₂O₅/graphene composite as a highly functional anode material for aqueous lithium-ion batteries.

Chenxiang’s research, “Design of Efficient, Reliable, and Wide-Band Filter Electrochemical Capacitors via Matching Positive with Negative Electrodes,” has been published in Joule. The study reveals that pairing electrodes with matched fast ion-exchange kinetics and high reversibility is key to achieving high performance in high-frequency, energy-dense applications.

Congratulations to Dr. Cheng-Wei!
