"Toward Sustainable Scaled-Up Synthesis of Lignin-Derived Carbon Nanoparticles Using a Furnace Aerosol Reactor: Insights from a Life Cycle Assessment" by Sujit Modi, Yash Shah, Onochie Okonkwo, Leanne M. Gilbertson Pratim Biswas has been published in American Chemical Society Environmental Science and Technology. Collaborative work by researchers from University of Miami College of Engineering / Washington University in St. Louis and Duke University https://lnkd.in/e-yeQrh9

Aerosol processing has been successful in preparing novel materials for a variety of applications in electronics, energy, environment, chemical industry and other sectors. The pathway can also promote "circular economies" and "sustainable production". This paper highlights an approach for sustainable scale up guided by life cycle analysis methodologies. American Association for Aerosol Research (AAAR) American Chemical Society University of Miami Department of Chemical, Environmental & Materials Engineering University of Miami Washington University in St. Louis Duke University

In recent years, significant progress has been made in the discovery and processing of advanced nanomaterials. However, the sustainability of their production is often overlooked in the interest of high performance and low cost. As the demand for these materials continues to grow, it is crucial to integrate circular economy principles into the design of alternative sustainable production technologies. Our work assesses the potential of an aerosol approach for the sustainable production of carbon nanomaterials from lignin (a waste byproduct of pulping industries). We employed life cycle assessment (LCA) as a design tool to enable low-impact production on a commercial scale. A sincere thank you to all collaborators for their help and contributions! #LifeCycleAssessment #CircularEconomy #AerosolSynthesis #lignin #Nanomaterials #SustainableMaterials

🌍 New Review Published! "Advancements and Challenges of Tailored Engineering of Carbon Materials for Electrolytic CO₂ Reduction to High-Value Carbon Products" The global climate crisis driven by excessive greenhouse gas emissions, especially CO₂, demands urgent and innovative solutions. One promising pathway is the electrochemical reduction of CO₂ into valuable carbon-based products — a transformative approach that not only mitigates emissions but also enables resource recovery and economic opportunities. Our latest review article provides a comprehensive overview of carbon-based catalysts — materials known for their cost-effectiveness, high conductivity, and tunable surface chemistry. We delve into: ✅ The latest advances in catalyst design ✅ Strategies like heteroatom doping and composite formation ✅ A detailed summary of performance metrics (FE, current density, stability) ✅ Key challenges and future directions in this rapidly evolving field 🔬 These tailored materials are central to enabling efficient, selective, and scalable CO₂ conversion technologies for a sustainable future. 💡 This work represents the collective effort of a dedicated research team, and I extend my special thanks to the corresponding authors Dr. SAHIL KOHLI and Dr. Indrani Jha for their leadership and guidance throughout this work. 📖DOI: https://lnkd.in/gThEXWED #CO2Reduction #Electrocatalysis #CarbonMaterials #Sustainability #ClimateAction #CarbonCapture #Research #GreenChemistry #EnergyTransition #NetZero

In environmental remediation, when it comes to tackling priority pollutants, what do you find more impactful? Is it: (A) Simply degrading them into harmless products, or (B) Transforming them into something useful and innovative? Or perhaps a secret option (C) achieving dual functionality with nanocomposites that can do both? As researchers, we often wrestle with these questions. That’s exactly what we have explored in our latest work, and I’m thrilled to share that it has just been published in the 𝑱𝒐𝒖𝒓𝒏𝒂𝒍 𝒐𝒇 𝑴𝒂𝒕𝒆𝒓𝒊𝒂𝒍𝒔 𝑺𝒄𝒊𝒆𝒏𝒄𝒆 & 𝑻𝒆𝒄𝒉𝒏𝒐𝒍𝒐𝒈𝒚 (𝑰𝒎𝒑𝒂𝒄𝒕 𝑭𝒂𝒄𝒕𝒐𝒓 14.3, 𝑪𝒊𝒕𝒆 𝑺𝒄𝒐𝒓𝒆 25.4)! ✨✨  Title: 𝑫𝒖𝒂𝒍-𝒇𝒖𝒏𝒄𝒕𝒊𝒐𝒏𝒂𝒍 𝑻𝒊³⁺-𝑻𝒊𝑶₂/𝑪𝒆𝑶₂ 𝑺-𝒔𝒄ℎ𝒆𝒎𝒆 ℎ𝒆𝒕𝒆𝒓𝒐𝒔𝒕𝒓𝒖𝒄𝒕𝒖𝒓𝒆𝒔 𝒇𝒐𝒓 𝒑ℎ𝒐𝒕𝒐𝒊𝒏𝒅𝒖𝒄𝒆𝒅 𝒏𝒊𝒕𝒓𝒐𝒑ℎ𝒆𝒏𝒐𝒍 𝒓𝒆𝒅𝒖𝒄𝒕𝒊𝒐𝒏 𝒂𝒏𝒅 𝒂𝒛𝒐 𝒅𝒚𝒆 𝒐𝒙𝒊𝒅𝒂𝒕𝒊𝒐𝒏: 𝑬𝒙𝒑𝒆𝒓𝒊𝒎𝒆𝒏𝒕𝒂𝒍 𝒂𝒏𝒅 𝑫𝑭𝑻 𝒊𝒏𝒔𝒊𝒈ℎ𝒕𝒔 📌Highlights from Our Study ▪️ Our Ti³⁺-TiO₂/CeO₂ heterostructure efficiently performs 𝐩𝐡𝐨𝐭𝐨𝐫𝐞𝐝𝐮𝐜𝐭𝐢𝐨𝐧 of nitrophenol and 𝐩𝐡𝐨𝐭𝐨𝐨𝐱𝐢𝐝𝐚𝐭𝐢𝐨𝐧 of toxic azo dye under controlled conditions; the dual functionality represents significant progress in sustainable environmental remediation. ▪️ Self-doped Ti³⁺ defects and 𝐞𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐞𝐝 𝐨𝐱𝐲𝐠𝐞𝐧 𝐯𝐚𝐜𝐚𝐧𝐜𝐢𝐞𝐬, combined with 𝐂𝐞³⁺/𝐂𝐞⁴⁺ 𝐯𝐚𝐥𝐞𝐧𝐜𝐲 𝐞𝐱𝐜𝐡𝐚𝐧𝐠𝐞 in the 𝐒-𝐬𝐜𝐡𝐞𝐦𝐞 𝐡𝐞𝐭𝐞𝐫𝐨𝐣𝐮𝐧𝐜𝐭𝐢𝐨𝐧, synergistically enhance photocatalytic activity, selectivity, and stability. ▪️ 𝐄𝐱𝐩𝐞𝐫𝐢𝐦𝐞𝐧𝐭𝐚𝐥 𝐬𝐭𝐮𝐝𝐢𝐞𝐬 𝐚𝐧𝐝 𝐃𝐅𝐓 𝐬𝐢𝐦𝐮𝐥𝐚𝐭𝐢𝐨𝐧𝐬 reveal how this system goes beyond pollutant degradation to enable value-added transformation with selective photocatalytic interactions.
