Some time ago we sent some samples of the co-extruded polypropylene backsheet to Stefan Mitterhofer from the National Institute of Standards and Technology (NIST) for further characterization. And as usual they have outdone themselves, surprising us with a very comprehensive study on the photo-oxidation stability of the backsheet. Here is the first paper, a second one is still under review. To summarize, the paper confirms our past results on the high stability of the co-extruded PP backsheets. The best way to show you is to quote the last paragraph of the paper: "The present work elaborates on previous studies revealing the excellent stability of these emerging PP-based backsheets, including general resistance to oxidative degradation as well as mechanical failure. These results, together with existing work showing the desirable functional properties of this material, highlight the promise of PP-based backsheets as an inexpensive, recyclable, and durable alternative to fluoropolymer-based backsheets in PV modules."

#QTNano: Two-Dimensional Perovskite Materials Perovskite-based solar cells have emerged as a promising technology due to their impressive efficiency and potential for low-cost production. However, two significant challenges remain: efficiently managing the material's stability from environmental degradation and eliminating toxic lead (Pb) from its composition. A possible solution lies in using thin films of two-dimensional (2D) perovskite materials and replacing lead with less harmful elements like germanium (Ge) and tin (Sn). This approach not only addresses the toxicity issue but also enhances the performance of the solar cells. Researchers have delved into the atomic-level differences between traditional three-dimensional (3D) perovskites and their innovative 2D counterparts. Using advanced computational methods, they have compared various physical and chemical properties of these materials. Their findings reveal that 2D perovskites exhibit stronger internal bonding due to the presence of organic spacers, which increases their stability. This stability is crucial for maintaining the material's integrity and performance over time. Moreover, the study highlights that these 2D materials have unique electronic and optical properties that make them highly effective in solar energy applications. For instance, lead-free perovskites made with germanium and tin show optimal band gaps for converting sunlight into electricity. https://lnkd.in/dhmthYa9

Tuesday publication update! 📖 In this newest publication in ACS Advanced Nano Materials, researchers from the #KULeuven have used the #AtmosphereAX system to look at passive adsorption materials for NOx removal. Authors Sreeprasanth Pulinthanathu Sree Claudio Bellani , Rainer Straubinger have investigated the dynamic behavior of palladium species impregnated onto zeolite under hydrothermal oxidation conditions, and using vapor! 🔬Using #Protochips' in situ gas phase TEM including the #AXON software, the formation and dispersion of Pd nanoparticles could be observed supported on a RHO zeolite. By heating the zeolite powder impregnated with a Pd complex up to 750°C within the TEM under an O2 atmosphere, water vapor, and argon, the dynamic evolution of Pd particles was shown. 🌡️ At lower temperatures, volatile masses began to form and gradually coalesced as the temperature increased. At the peak temperature of 750°C, a dispersal process occurred, releasing highly mobile smaller particles. This behavior underscores the intricate dynamics of Pd species under these conditions. ⚙️ The in situ TEM studies captured the dynamic changes of Pd nanoparticles, revealing mechanisms such as rapid thermally induced reduction and Ostwald ripening. These insights are crucial for optimizing and preparing supported noble-metal materials and catalysts. Studies like these enhance the understanding of nanoparticle formation on supports for catalysis and underscore the potential of in situ TEM as a powerful method for investigating and improving the synthesis of various catalytic nanomaterials.

#Great_Opportunity Heterofunctionnal catalysts for the Hydrogen Evolution Reaction and Alcohols Electro-oxidation Reaction in alkaline membrane electrolyzer at jennifer person, France. Offer Description: Hydrogen is expected to play a pivotal role in the upcoming energy transition but the shift towards a "net-zero emissions" scenario necessitates a move from fossil fuel-based hydrogen production to "green" hydrogen production systems. In this context, electrolysis of water emerges as the most promising technology. However, a major obstacle to large-scale hydrogen production through water electrolysis is the cost of electricity, mainly influenced by the high overpotential required for water oxidation at the anode of electrolysis devices. A promising approach to reduce the cost of hydrogen production is to replace the water oxidation reaction with the oxidation of an alcohol molecule. This offers two significant advantages: (1) the oxidation of alcohol occurs at lower potentials, potentially significantly lowering the electrolyzer cell voltage and consequently reducing the energy required for hydrogen production and its cost; (2) additionally, the oxidation of oxygenated feedstocks, possibly biosourced, instead of oxygen evolution, could allow for the co-production of high-value-added molecules (acids, esters, lactones, etc.). Simultaneously, the interest in heterofunctional catalysts, where at least two types of nanoparticles are associated to maximize the number of interfaces, has been demonstrated in alcohol oxidation reactions via thermal routes and hydrogen evolution reaction. The objective of this PhD project, at the intersection of various expertise areas within the hosting team, is to synthesize heterofunctional catalysts and evaluate their catalytic properties toward the hydrogen evolution reaction and electro-oxidation of alcohols in an alkaline environment. The materials will be obtained using solution synthesis techniques and characterized by a wide range of physico-chemical characterization techniques available in the laboratory (XRD, SEM, TEM, XPS, etc.). The study of catalyst reactivity in three-electrode electrochemical cells but also through operando approaches such as electrochemistry-X-ray absorption spectroscopy and electrochemistry-transmission electron microscopy will contribute to a better understanding of the relationships between the heterofunctional structure of catalysts and their properties for the target reactions. Finally, the most promising materials will be processed to be integrated and tested into anion exchange membrane (AEM) electrolysis cells. This last aspect will contribute to the development of an emerging electrolysis technology, where AEM electrolyzers combine hydrogen production and the production of high-value-added molecules.

*****New Publication Alert ***** New paper in American Chemical Society’s #ACSEnergyLetters journal. “Electrolyte Intermolecular Interaction Mediated Nonflammable Potassium-Ion Sulfur Batteries” The design of electrolytes that are compatible with graphite electrodes and incorporate flame-retardant properties in potassium-ion batteries (PIBs) can not only facilitate their commercialization but also improve the safety reliability. However, it remains challenging, particularly in propylene carbonate (PC)-based electrolytes. Herein, we achieved a highly reversible K+ (de)intercalation with graphite in PC-based electrolytes by introducing the fluoroethers. We identified the strength of interactions formed between fluoroethers (e.g., 1,1,2,2-tetrafluoroethy-2,2,3,3-tetrafluoropropyl ether (HFE), 1,1,2,2-tetrafluoroethyl 2,2,2-trifluoroethyl ether (TFTFE)) and PC by heteronuclear overhauser effect spectroscopy. We find that the interaction between HFE and PC is stronger, which can significantly weaken the K+-PC interaction, contributing to a reversible K+(de)intercalation and also endowing electrolyte nonflammable features. The kinetic and thermodynamic properties of K+-solvent-anion complexes in the proposed interfacial model can elucidate the electrolyte and electrode stability, enabling the as-designed potassium-ion sulfur batteries to show high performance. This discovery offers a fresh perspective for designing and advancing electrolytes in PIBs and beyond. https://lnkd.in/gEiQyUgN Stay tuned for more exciting news from the School of Physical Sciences at Jawaharlal Nehru University, New Delhi, India. #JNU, #SPS #SPSJNU #KIonBattery #Cathode #Anode #PotasiumSulfur #Electrolyte #nonflamableelectrolyte #graphiteanode #SPANCathode #ElectrolyteAdditives #ElectrolyteMicrostructures #KSBatteries #InterMolecularInteraction #PotasiumSulfurBatteries #EnergyStorage #Batteries #ElectrolyteSolvationChemistry #InterfacialModel #ACS #AmericanChemicalSociety #ACSEnergyLetters Jawaharlal Nehru University (JNU) Dr. Prashant Tripathi Avinash Rundla Divya Rani Raghuvanshi Shivani Singh Rajkamal Arya Manjusha Shelke

#XRD, #XRF, and #SEM are advanced analytical techniques widely used in #materialcharacterization to determine the composition, structure, and properties of materials. Each technique offers unique insights into the material being studied. Here's an overview of each: 1. X-ray Diffraction (XRD) Purpose: To determine the crystallographic structure, phase composition, and orientation of materials. How It Works: XRD uses X-rays directed at a material, which then diffract in specific patterns depending on the atomic arrangement within the crystal lattice. By analyzing these diffraction patterns, one can identify the crystalline phases present in the sample and gain information about the crystal structure, unit cell dimensions, and even particle size. Applications: Identifying phases in minerals, metals, and ceramics. Measuring crystallite size and strain. Studying phase transitions and texture in materials. Example: Determining the phase composition of a cement sample to understand its hydration properties. 2. X-ray Fluorescence (XRF) Purpose: To determine the elemental composition of a material. How It Works: XRF involves bombarding a material with high-energy X-rays, which cause the atoms in the material to emit secondary (fluorescent) X-rays. These emitted X-rays have energies characteristic of the elements present in the material. By analyzing the energy and intensity of these fluorescent X-rays, the elemental composition can be determined, both qualitatively and quantitatively. Applications: Rapid analysis of the elemental composition in solids, powders, and liquids. Quality control in industries like cement, metals, and glass. Detecting trace elements in environmental samples. Example: Determining the concentration of various oxides (like SiO₂, Al₂O₃, Fe₂O₃) in a cement sample. 3. Scanning Electron Microscopy (SEM) Purpose: To visualize the surface morphology and microstructure of materials at high magnifications, often combined with elemental analysis. How It Works: SEM uses a focused beam of electrons to scan the surface of a material. The interaction of the electrons with the sample generates various signals (secondary electrons, backscattered electrons, etc.) that are collected to form an image of the surface. SEM can also be equipped with an Energy Dispersive X-ray Spectroscopy (EDS or EDX) detector to perform elemental analysis. Applications: Detailed imaging of surface features, fractures, or defects in materials. Studying the morphology and size distribution of particles. Conducting elemental analysis at specific locations on the sample (using EDS). Example: Imaging the microstructure of a protective coating to assess its uniformity and detect any defects. Summary of Applications: XRD: Best for determining crystal structures and phases in crystalline materials. XRF: Ideal for fast and accurate elemental composition analysis. SEM: Excellent for visualizing surface morphology and conducting localized elemental analysis.

#QTNano: Perovskite materials have garnered significant attention in the field of solar cell technology due to their exceptional optoelectronic properties and ease of fabrication. One aspect of perovskite materials that researchers are particularly interested in is their phase transition behavior. These materials can undergo structural transformations, such as transitioning from a cubic to a hexagonal phase, under certain conditions. Understanding and harnessing these phase transitions are crucial for optimizing the performance and stability of perovskite solar cells. The transition from a cubic to a hexagonal phase, for example, can significantly alter the electronic and optical properties of the material. This phase transition may lead to changes in the bandgap, carrier mobility, and defect density, which in turn affect the efficiency and stability of solar cells. Moreover, the phase transition behavior of perovskite materials can be influenced by external factors such as temperature, pressure, and chemical composition. By carefully controlling these parameters, researchers can tailor the phase transition process to achieve desired material properties and device performance. #QTNano #DFT #Perovskites #structures #phasetransition https://lnkd.in/dASxjgcp

#Perovskites: https://lnkd.in/d9z2fZNr Tin-based ASnI3 perovskites have been considered an excellent candidate for lead-free perovskites solar cell applications, however, our atomistic understanding of the role of A-cations in the physical chemistry properties is far from satisfactory. Here, we report a density functional theory investigation of the role of A-cations, namely, CH3NH3 (methylammonium), CH3 PH3 (methylphosphonium) and CH(NH2)2 (formamidinium), in the structural-stability of different ASnI3 perovskites and non-perovskite structures; where several orientations of A-cations were considered for cubic, orthorhombic, tetragonal and hexagonal phases.
