LSU Department of Chemistry’s Post

‼️ Throwback Monday ‼️ In 2023, my first ( 🥇 ) paper of the PhD, "A combined computational and experimental study of metathesis and nucleophile-mediated exchange mechanisms in boronic ester-containing vitrimers", was published in Polymer Chemistry. It marked a significant step in understanding and optimizing dynamic polymer networks. 🔍🧪  💡Key Achievements: 🖥️ Blending DFT simulations and experimental work, we explored how boronic esters exchange bonds through metathesis and nucleophile-mediated pathways. ♻️Highlighted the potential of nucleophiles to drastically speed up bond exchange kinetics, paving the way for more efficient, reprocessable materials 🌱Showcased the practical implications in creating vitrimers with faster relaxation dynamics, aligning with the goals of sustainability and circular materials. If you missed it, the full open-access article is here: DOI: 10.1039/d3py01047c  Thanks to my co-authors: Daniele Mantione, Marta Ximenis Campins, haritz sardon muguruza, Nicholas Ballard, and Fernando Ruipérez. #Vitrimers #Sustainability #PolymerScience #DynamicMaterials

Congratulations to the team Hailong Chen, Zhantao Liu (GaTech), Jue Liu (ORNL), Shuo Wang for achieving the world-record high conductivity in halide solid electrolyte! Our computation based on the Density of Atomistic States (DOAS) has revealed the mechanisms and promises of mixed anion systems in achieving high ionic conductivity https://lnkd.in/eNnddyPY

✨ Seminar Insights: Unconventional Ligand Designs for Optically Interesting Coordination Complexes ✨ Today, I had the opportunity to attend a fascinating seminar by David Herbert from the Chemistry Department at the University of Manitoba. The seminar focused on the design of ligands for 3D coordination complexes, exploring how modifying the properties of ligands can extend the decay time of Metal-to-Ligand Charge Transfer (MLCT) transitions—key to developing materials with unique optical properties. It's always inspiring to learn about innovative approaches in ligand design and how they can influence materials science and catalysis. #CoordinationChemistry #LigandDesign #OpticalProperties #MaterialsScience #ResearchInsights #ChemistryCommunity #UniversityofManitoba

Recently my first co-authored paper during my PhD at Osaka University, Graduate School of Engineering was published in the scientific journal, Chemical Communications, for ChemComm's 60th Anniversary collection, under the Royal Chemistry Society. It describes a new phenomenon called chirality-induced spin selectivity (CISS) that is theoretically exhibited in all chiral materials. The project was in collaboration with my senior Shuang Li, a fellow PhD student in my lab. In our paper, we observed in chiral bifacial IDT-based π-conjugated polymers a spin polarization of nearly 70%. Where spin polarization is the amount of electron spins that are filtered by the chiral material and a spin-biased current is generated (only up or down spin). CISS shows great promise for spintronic applications like quantum computing, asymmetric reactions, and oxygen reduction. It was a fun project to work on and I was glad to be part of it. I look forward to what more we will find by exploring CISS! https://lnkd.in/gSFRKu47

👏Newest JRA Publication ! Improved spectral resolution now overcomes sensitivity limits of small samples, enabling routine analysis of complex materials. Published in the Angewandte Chemie International, the publication highlights the routine characterization of these complex materials, with potential applications in catalyst optimization and the development of next-generation batteries, particularly those used in electric vehicles and microgrids The new capability resulted from an industry-academia collaboration between CRMN Lyon, University of Cambridge, IFPEN, and Bruker Biospin. 🌐 You can find the publication in open-access here: https://lnkd.in/da9itKAg

Research by Maxx Arguilla and colleagues, Steven Allison, Dmitri Leo Cordova, Maham Hasi and Toshihiro Aoki, was recently published by the Royal Society of Chemistry. Their work demonstrates the growth of Bi4I4 nanowires and nanosheets assisted by gold #nanoparticles. The size and morphology of these structures are contingent upon the dissolution of Bi and I within the gold nanoparticle catalysts. These Bi4I4 formations serve as valuable subjects for investigating the impact of size, composition, and shape on their unique properties. Given the resemblance of Bi4I4 to other one-dimensional (1D) crystals, these findings offer insights that could inform the synthesis of such crystals utilizing analogous catalyst-based methods. https://lnkd.in/g9bBcEMM

🎉 Our latest research paper, "Differential Pulse Voltammetry: Evolution of an In Vivo Methodology and New Chemical Entries, A Short Review," has been published in the Journal of New Developments in Chemistry. This peer-reviewed open access journal highlights the evolution of a vital methodology in chemistry. 🔍 This study delves into the fascinating history of voltammetric techniques, tracing back to Heyrovsky's discovery in 1924. Did you know that the current at a mercury electrode isn't directly proportional to the applied voltage? Instead, it's influenced by oxidizable chemicals in the solution, leading to the emergence of polarographic and voltammetric currents. ⚡ Explore various voltammetric techniques like chrono-amperometry, linear voltammetry, cyclic voltammetry, and pulse voltammetry. These dynamic methodologies analyze oxidation or reduction potentials and the release of electrons by the chemicals under scrutiny. 📖 For those interested in diving deeper into this groundbreaking research, check out the full article here: https://lnkd.in/gNDCwi-B. Stay tuned for more updates from the forefront of chemistry! #ChemistryResearch #Voltammetry #ScienceInnovation

We’ve just published in Cell Reports Physical Science a novel approach to fine-tune the structure and stability of MXenes using unmodified kraft lignin. Our study shows that lignin acts as a modular intercalant and surfactant for Ti3C2Tx, allowing dynamic control over the interlayer spacing and greatly enhancing both colloidal stability and oxidation resistance. The electron transport within MXene-lignin complex follows the Mott hopping mechanism quite well. We also studied the response of this material to IR and GHz. This sustainable and cost-effective solution opens up new possibilities for electronics and optics applications with MXenes. Excellent collaboration between Aalto University (Xiaodan Hong, Jin Zhang, Jiali Sheng, Jiahui Kang, Bo Peng, and Olli Ikkala) and the Chinese Academy of Forestry (Pan Jiang, Yanming Han, and Fuxiang Chu).

I am thrilled to announce that our paper on "The effect of process variables on Near-field electrospinning of Polycaprolactone studied by Response Surface Methodology" has been published in the Iranian Polymer Journal. Previously, I discussed the methods and parameters of Near-field electrospinning (NFES) in a review article titled "Near-Field Electrospinning: Crucial Parameters, Challenges, and Applications." In this new article, we delved into the five key parameters that influence the production of polycaprolactone fibers via NFES. These parameters impact fiber diameter size, deposition accuracy, and fiber morphology. Response Surface Methodology was utilized to draw more robust conclusions in this research. I hope that this study will prove beneficial in optimizing the NFES method. https://lnkd.in/d3e_jncB #Near_field_electrospinning #Additive_manufacturing #micro_fibers #electrospinning

Happy to share the first publication of 2025 out in Chemical Science, the flagship journal of the RSC. It discusses a supramolecular polymer system formed solely from water and a small amphiphilic crown ether. This supramolecular polymer exhibits adhesive properties down to –80 °C. The state of water in the system was characterized in detail using broadband dielectric spectroscopy (BDS) and fast scanning calorimetry (FSC) at Bundesanstalt für Materialforschung und -prüfung https://lnkd.in/eg99NvJn
