Gas marbles are a new family of particle-stabilized soft dispersed system with a soap bubble-like air-in-water-in-air structure. ⚪ @Prof. Dr.-Ing. Silke H. Christiansen, @Dr. Sabrina Pechmann and Dr. @Hyoungwon Park together with researchers from the Osaka Institute of Technology, the Université de Lille and the University of Hyogo, have produced hydrophobic polymer granules that encase these gas marbles. The resulting marbles can be used to safely transport gases across the surface of a liquid and then release them via chemical triggers. Our task was to use high-resolution computer tomography to obtain a virtual and thus non-destructive view of the inside of the gas marbles and thus to determine their structure in more detail.

#QTNano: Unraveling Mysteries of Sodium-Ion Transport in Deep Eutectic Solvents The quest for efficient and sustainable energy storage solutions has led researchers to explore novel materials, and one promising avenue is the use of deep eutectic solvents (DES) in sodium-ion (Na+) batteries. Our recent study, published in the Journal of Molecular Liquids 2024, delves into the complexities of the NaTFSI:NMA (sodium bistrifluoromethane sulfonyl imide-N-methyl acetamide) system, shedding light on its atomistic behavior. 🌐 Advancing Understanding Through Simulation While DES have shown promise, our current grasp of their atomistic behavior remains in a state of evolution. To bridge this gap, the research team employed a combination of classical force field molecular dynamics (MD) simulations and periodic density functional theory (DFT) calculations. 🧠 Enhancing Atomistic Understanding Our results were obtained with self-consistent MD/DFT calculations, assigning effective charges to all atoms while keeping other OPLS parameters constant. Our team observed that as the Na+ mole fraction increased, diverse chemical environments emerged, resulting in larger aggregates, low conductivity, and high viscosity within the electrolyte. Despite temperature changes, the liquid structure remained consistent. Higher temperatures were found to decrease the lifetime of ionic pairs and enhance Na+ ion mobility. 🔗 Unraveling Hydrogen-Bond Networks The study also explored the intricate hydrogen-bond network formation within the NMA-NMA species. The disruption of these bonds increased with rising Na+ concentration, shedding light on the structural transformations occurring during battery operation. 🔄 Periodic DFT Insights Periodic DFT calculations revealed a fascinating aspect of the reduction process—the substitution of atomic sites from NMA to TFSI. This dynamic process provides crucial insights into the system's behavior under electrochemical conditions. ⚡ Electrochemical Stability Windows (ESWs) The results of ESW calculations presented a compelling case for the system's robustness at higher salt concentrations, suggesting effective safeguarding of the solvent from degradation. This finding is crucial for the long-term stability and viability of NaTFSI:NMA DES in practical battery applications. https://lnkd.in/dHbFyv6F #EnergyStorage #SodiumIonBatteries #ScientificAdvancements #RenewableEnergy #MolecularLiquids

Check out our new article published in ACS Langmuir. 😊 In this study, we present a facile preparation method for HfO2 hollow fibers through a unique integration of the sol−gel process and electrospinning technique. Initially, polystyrene(PS)fibers are fabricated by using electro-spinning, followed by dipping in an HfO2 precursor solution, resulting in HfO2-coated PS fibers. Subsequent thermal treatment at 800°C ensures the selective pyrolysis of the PS fibers and complete condensation of the HfO2 precursors, forming HfO2 hollow fibers. Application in the field of filtration, energy storage, and memory devices are expected.

Infrared heaters provide warmth in the living room, terrarium or canteen display. This type of heat transfer between particles also plays an important role in industrial processes, for example in iron processing or lime burning, where bulk material is heated in massive ovens. One area of research at the department of Energy Plant Technology at Ruhr University Bochum, led by Martin Schiemann, is the investigation of this heat transfer between particles in packed beds. An arrangement of metal or mineral rods serves as a model system. A unique experiment based on a modified IRTracer-100 was developed for measuring the emissions.

📰 We would like to share with you this paper,"Experimental validation of a vanadium redox flow battery model for state of charge and state of health estimation", from our #memberBatteryPlat CSIC 🔗   https://lnkd.in/eTt3WgxJ ✍ Abstract: This study presents a vanadium redox flow battery model that considers the most important variables that have a crucial role in the performance of the system. A complete model divided in an electrochemical, thermal, hydraulic and voltage submodels is presented. The analytic analysis of the model is carried out to reduce the system order according to some conservation laws. Based on this analysis, a subsequent calibration of the model parameters is developed using real experimental data. The validation is performed comparing the real measured voltage and the one estimated with the model. To calibrate the model an algorithm based on the implementation of a particle swarm optimizer is used. Results obtained in both short and long-term operation are presented, in order to compare and validate if the model can be used for both state of charge and state of health estimation. 🌍 www.batteryplat.com #AlmacenamientoEnergético #BatteryPlat #PlataformasTecnologicas #PaperBatteryPlat

We can answer: Why degrade Solid state batteries in operation? Monitoring batteries in operando is one of the keys we do with our synchrotrone Bessy II in Adlershof Helmholtz-Zentrum Berlin. What we get: very valuable insights into the real process whilst charging and decharging. Elmar Kataev analysed the electrochemical reactions at the interface between the common solid electrolyte Li6PS5Cl and a very thin layer of Nickel electrode with high temporal resolution. The result: the decomposition reactions were only partially reversible. These insights give you the chance to go ahead with develpoments on next generation batteries in your company. Let me know if you would be interested in analytics of your batteriecell! (No matter if solid state of liquid electrolytes) We do look for cooperations as we would like to extend our know-how eg on hybrid solid states or investigate varieties of anode and cathode materials.
