Happy Teachers’ Day!
Thank you to all my students for your warm and thoughtful messages. Seeing you grow, make progress, and achieve your goals is truly the greatest joy and reward for a teacher. Wishing everyone continued success and a wonderful journey ahead!
BEST Lab Semester Kickoff Gathering
We kicked off the new semester with a BEST Lab gathering, welcoming new members and wishing our graduating and departing members all the best on their next journey. It was a wonderful chance to celebrate both new beginnings and memorable farewells. Here’s to a great start and a productive, rewarding semester ahead!
Congratulations to Our Summer Graduates! 🎓
Congratulations to Ralph, Thu, Kevin, and Jacky on your graduation this summer! 🎓 Wishing you all the very best as you begin the next chapter of your journey. May everything ahead go smoothly and bring you new opportunities and success. Bon voyage and best wishes for the future!
Our new paper in Applied Surface Science (Q1) "Conformal AlN-Derived Interphases Grown by Atomic Layer Deposition for Mitigating Interfacial Degradation of Silicon Anodes in Li-ion Batteries"
Silicon anodes suffer from severe interfacial degradation during repeated lithiation and delithiation, limiting their long-term electrochemical stability. In this work, conformal AlN-derived interphases were constructed on porous silicon electrodes by atomic layer deposition (ALD) to investigate their interfacial evolution and electrochemical behavior. Structural characterization confirmed the formation of a conformal coating layer. Depth-resolved X-ray photoelectron spectros
Our new paper in Surfaces & Interfaces (Q1) "Atomic Layer Deposited Tantalum Nitride-Derived Interphases for Improving Interfacial Charge Transfer in Silicon Anodes for Lithium-ion Batteries"
Silicon anodes suffer from severe interfacial degradation caused by repeated volume changes during electrochemical cycling, resulting in rapid capacity decay and increased polarization. Herein, tantalum nitride (TaN)-derived interphases were formed on silicon particles within porous electrodes by atomic layer deposition to stabilize the electrode-electrolyte interface. Electron microscopy revealed a continuous and conformal TaN-derived interphase on the examined Si particles,
Our new paper in Small (IF:11.8) "Electrostatic Regulation of Sulfur Spatial Evolution for Dimensionally Stable Lithium–Sulfur Batteries"
Lithium–sulfur (Li–S) batteries are promising for high-energy storage but are limited by complex multistep sulfur redox reactions that induce polysulfide migration, sluggish conversion kinetics, and severe cathode swelling. Here, we report a boron nitride/carbon nanotube (BN/CNT) heterostructure that enables electrostatic regulation of sulfur spatial evolution through the separation of polar domains and conductive networks. The conductive CNT scaffold preserves electron perco
