We are happy to share that the manuscript “Iridium-Based Materials as an Electrocatalyst in Computational Investigation of Its Performance for Hydrogen and Oxygen Evolution Reactions”, authored by Marionir Castelo Branco, Pedro Ivo R. Moraes, and Juarez L. F. Da Silva, has just been accepted for publication in ACS Applied Energy Materials! This study combines density functional theory (DFT) and the computational hydrogen electrode (CHE) model to unravel the atomic-level mechanisms governing the performance of metallic iridium and its oxides (IrO₂ and Ir₂O₃) as electrocatalysts for hydrogen and oxygen evolution reactions (HER and OER). The work highlights how surface structure, oxidation state, and electronic properties influence the catalytic activity, offering fundamental insights for the rational design of advanced catalysts for water splitting and sustainable hydrogen production. 🌱💧⚙️ Congratulations to the authors for this significant contribution to the field of computational catalysis and renewable energy materials! 👏👏 #ComputationalChemistry #Electrocatalysis #WaterSplitting #HydrogenEnergy #Iridium #DFT #ACS #QTNano #USP #ScientificAchievement

We’re excited to share our latest paper led by our PhD student Koray Yıldırım 🎉 Why do we explore novel gas diffusion layer (GDL) designs? Because it makes sense: 1️⃣ We demonstrate that the challenging water management and thus performance&durability of hydrocarbon-based catalyst-coated membranes can be significantly improved through a novel GDL/MPL architecture designed for their needs. 2️⃣ Moving beyond perfluorinated polymers—not just in ionomers and membranes, but throughout the entire membrane-electrode-assembly—is key to achieving a fully PFAS-free solution for electrochemical converters, unless it’s for #fuelcells, #electrolyzers, #CCUS, or other emerging electrochemical applications🌱⚡ 👏 Congratulations to Koray for developing and thoroughly characterizing these novel PFAS-free gas diffusion layers and publishing his third and last paper of this PhD thesis! We gratefully acknowledge funding from the Bundesministerium für Forschung, Technologie und Raumfahrt within the 105scaled project, in collaboration with our fantastic partners Hahn-Schickard and Albert-Ludwigs-Universität Freiburg. 🙏 📄 Read the open-access paper here: 🔗https://lnkd.in/eesD8jF6

How can solar cells become more accessible to everyone? Scientists around the world are seeking the answer – and FTMC has also taken a step towards a deeper understanding. ☀️ 🔋 On 15 October, physicist Muhammad Mujahid successfully defended his doctoral dissertation. His research topic was “Triple Cation Perovskite Layer Fabrication and Investigation of their Optoelectronic Properties for Tandem Solar Cells” (academic supervisor: Prof. Habil. Dr Steponas Ašmontas from the FTMC Laboratory of Electronic Processes). The physicist explored how to harvest more electrical energy from sunlight using perovskite solar cells. Perovskites are a type of crystalline material that scientists hope could replace conventional silicon in solar cells, making solar energy cheaper, more efficient, and easier to integrate into everyday life. However, there is still a long way to go before perovskite solar cells are widely used. The main challenges concern their stability, resistance to environmental effects, and other key factors. Muhammad’s work aims to contribute to overcoming these challenges. 💬 “Higher efficiency lowers the cost per watt and harvests more energy from rooftops, apartments, factories, and carports, exactly where space is tight. Semi-transparent perovskites make it easier to embed photovoltaics into windows and facades, turning city buildings into quiet power plants without sacrificing natural light, a big win for dense urban areas,” says Dr Mujahid. We warmly congratulate our colleague and wish him continued success in his scientific career! 🎉 _____ #FTMC #Perovskite #SolarCells #Energy #RenewableEnergy #Science #PhD #Physics #Sun #Silicon #MuhammadMujahid #Optoelectronics #Electronics

🔬 Product Series – X-ray Gas Heating: 3 of 3 How does ethylene hydrogenation transform supported Pt catalysts? Hummingbird Rewind: As part of our three-part series featuring the new X-ray gas heating sample holder, we recall an early demonstration of the method from Yuanyuan Li and Anatoly Frenkel from Yeshiva University, along with their colleagues from Brookhaven National Laboratory, the University of Illinois Urbana-Champaign, and KTH Royal Institute of Technology. The Hummingbird Scientific gas flow X-ray sample holder (https://lnkd.in/gRTGjGjE) was used to characterize the structural evolution of supported Pt nanocatalysts during ethylene hydrogenation. The team combined correlated synchrotron XAS including XANES and EXAFS with STEM to demonstrate dynamic transformations across a broad range of cluster sizes. Substantial restructuring of Pt catalysts was demonstrated across a wide range of cluster sizes. Metal clusters fragmented into smaller clusters in the sub-nm range followed by coalescence into larger particles. The results will inform future supported Pt nanocatalyst process optimization, while the method coupling XANES, EXAFS, and STEM techniques can be applied to a broad range of mechanistic investigations into dynamic reactions across nanocatalyst systems and length scales. 👇 See the comments below for a link to the full paper. ➡️ Stay tuned for more posts exploring capabilities of this holder.    🔔 Follow Hummingbird Scientific to stay up to date on the latest in-situ EM and spectroscopy news. #XAS #XANES #EXAFS #STEM #nanocatalyst #hummingbirdscientific #nanotechnology #materialsscience #catalysis #C2H4hydrogenation #synchrotron

CEA-Leti researchers have developed a miniaturized Electron Paramagnetic Resonance (EPR) spectrometer that brings lab-grade analysis into a portable form. Using compact permanent magnets and integrated circuits originally designed for telecommunications, the new design operates on just a few watts, rather than tens of kilowatts. The project, supported by CEA’s Carnot and Moonshot programs, could make on-site EPR analysis practical across various fields, including medicine, materials science, and energy applications.

In a study recently published in ECS Advances, Lin Ma, Ph.D., senior author and assistant professor in the Department of Applied Physical Sciences, with Ph.D. students Michael Chak and Vadim Shipitsyn, investigated why sodium-ion batteries lose capacity and efficiency over time, especially when operated at high temperatures and voltages. Their findings point to a surprising culprit: interactions between the two ends of the battery—the #cathode and the #anode. Traditional sodium-ion batteries use a “hard carbon” anode. While reliable, it doesn’t store much energy. The University of North Carolina at Chapel Hill team replaced it with a tin alloy anode, which can hold much more sodium, boosting the battery’s volumetric energy density—essentially, how much energy fits into a given space. That makes tin anodes especially appealing for grid-scale energy storage, where compactness and capacity are key. “The tin anode offers a major jump in how much energy the battery can store,” said Chak, below holding a sodium-ion battery and lead author of the study. “But the trade-off is that the battery doesn’t last as long. We wanted to know why.” Read the story on the APS website: https://bit.ly/4oyW9Zw UNC College of Arts and Sciences #cleanenergy #interphase #batteries #renewableenergy #lithium #sodium UNC Research
