In PRL's latest forward-looking Essay, Jun Ye and Peter Zoller argue for using quantum sensing and atomic, molecular, and optical (AMO) techniques to proble fundamental physics. For example, quantum clocks could probe gravity, looking for permanent electric dipole moments of elementary particles can probe physics beyond the standard model, and quantum sensors could help us understand strongly interacting many-body systems.

In this presentation, Anthony Richardella, an associate research professor specializing in x-ray scattering at the Materials Research Institute, Penn State, speaks on the topic, "Methods for Determining Crystallite and Single Crystal Orientation." This talk explores the idea that for many materials the direction (or orientation) of the crystal planes impacts the overall properties. The simplest example is the difference between a single-crystalline and polycrystalline sample. But even polycrystalline samples need not be completely random; some crystalline planes may preferentially align with certain directions. Such a sample is said to be oriented or textured. Orientation influences grain boundaries, mechanical and electrical properties, and more. We will discuss X-ray scattering, electron microscopy, and other methods available in the MCL that can be used to determine the orientation of crystalline domains across a range of materials. https://okt.to/up7fUg #MaterialsCharacterization #XRD #XRDtraining #xraydiffraction #ElectronMicroscopy

New Article Alert: “High Voltage Electrolyte Design Mediated by Advanced Solvation Chemistry Toward High Energy Density and Fast Charging Lithium-Ion Batteries” @Advanced Energy Materials. https://lnkd.in/gfSMjiwC Electrolyte is critical for transporting lithium-ion (Li+) in lithium-ion batteries (LIBs). However, there is no universally applicable principle for designing an optimal electrolyte. In most cases, the design process relies on empirical experiences and is often treated as highly confidential proprietary information. In the article, a solvation structure-related model for the quantitative design of electrolytes is introduced, focusing on the principles of coordination chemistry. As a paradigmatic example, a high-voltage electrolyte (i.e., 4.5 V vs anode) aimed at achieving a high energy density and fast charging LIB, which is specifically composed of an emerging, well-constructed hybrid hard carbon-silicon/carbon-based anode, and lithium cobalt oxide cathode, is developed. Not only the functions of each electrolyte component at the molecular scale within the Li+ solvation structure are analyzed but also an interfacial model is introduced to elucidate their relationship with the battery performance. This study represents a pioneering effort in developing a methodology to guide electrolyte design, in which the mutual effects of the Li+ de-solvation process and solid electrolyte interface (SEI) on the electrode surface are explored concurrently to understand the root cause of superior performance. The innovative approach presented in the paper, establishes a new paradigm in electrolyte design, providing valuable insights at the molecular level.

*****New Publication Alert ***** New paper in American Chemical Society’s #ACSNano journal.   “Thermodynamic and Kinetic Behaviors of Electrolytes Mediated by Intermolecular Interactions Enabling High-Performance Lithium-Ion Batteries”. Electrolyte solvation chemistry regulated by lithium salts, solvents, and additives has garnered significant attention since it is the most effective strategy for designing high-performance electrolytes in lithium-ion batteries (LIBs). However, achieving a delicate balance is a persistent challenge, given that excessively strong or weak Li+-solvent coordination markedly undermines electrolyte properties, including thermodynamic redox stability and Li+-desolvation kinetics, limiting the practical applications. Herein, we elucidate the crucial influence of solvent–solvent interactions in modulating the Li+-solvation structure to enhance electrolyte thermodynamic and kinetic properties. As a paradigm, by combining strongly coordinated propylene carbonate (PC) with weakly coordinated cyclopentylmethyl ether (CPME), we identified intermolecular interactions between PC and CPME using 1H–1H correlation spectroscopy. Experimental and computational findings underscore the crucial role of solvent–solvent interactions in regulating Li+-solvent/anion interactions, which can enhance both the thermodynamic (i.e., antireduction capability) and kinetic (i.e., Li+-desolvation process) aspects of electrolytes. Additionally, we introduced an interfacial model to reveal the intricate relationship between solvent–solvent interactions, electrolyte properties, and electrode interfacial behaviors at a molecular scale. This study provides valuable insights into the critical impact of solvent–solvent interactions on electrolyte properties, which are pivotal for guiding future efforts in functionalized electrolyte engineering for metal-ion batteries. https://lnkd.in/gzshmv6J Stay tuned for more exciting news from the School of Physical Sciences at Jawaharlal Nehru University, New Delhi, India.    #JNU, #SPS #SPSJNU #LiIonBattery #Cathode #Anode #Electrolyte #graphiteanode #ElectrolyteAdditives #ElectrolyteMicrostructures #InterMolecularInteraction #EnergyStorage #Batteries #1H1Hcorrelationspectroscopy #desolvationkinetics #solventsolventinteractions #Lisolventanioninteractions #ElectrolyteSolvationChemistry #InterfacialModel #ACS #AmericanChemicalSociety #ACSNano Jawaharlal Nehru University Dr. Prashant Tripathi Avinash Rundla Divya Rani Raghuvanshi Shivani Bharti Rajkamal Arya Manjusha Shelke

Check out our latest research article "On the cyclic deformation behavior of wire-based directed energy deposited Fe-Ni Invar alloy", now published in Materials Science and Engineering: A 📚. 🚀After presenting the study with a poster at #MSE2024 in Darmstadt and with a talk at MS&T in Pittsburgh, I am very excited that our paper is finally published open access! Feel free to check out the full paper here: https://lnkd.in/eb-Ps5yb The paper focuses on microstructural evolution and structural integrity of the Fe-Ni36 Invar alloy manufactured by wire-based directed energy deposition (DED) employing either an electric arc (DED-Arc) or a laser beam (DED-LB) as energy source. It has to be noted, that a wire-based DED-LB Invar condition is comprehensively studied for the first time in open literature. 💡The study revealed that the DED-LB condition is characterized by a heterogeneous grain size distribution, less pronounced crystallographic texture as well as increased tensile strength and ductility compared to the DED-Arc counterparts. Despite increased strength and ductility, the DED-LB Invar consistently shows inferior fatigue properties. This behavior is discussed based on microstructural heterogeneity, cyclic deformation response, process-induced porosity and the contribution of plastic strain. Furthermore, investigations on the thermal expansion behavior show that the DED Invar retains its outstanding thermal properties, respectively. This research represents another excellent output of my collaboration with my good friend Dr.-Ing. Johannes Günther from ifw Jena | Günter-Köhler-Institut für Fügetechnik und Werkstoffprüfung GmbH. Special thanks to Johannes and his team at this point for this fantastic teamwork. Moreover, I would like to thank my co-authors Dr. Sudipta Pramanik as well my supervisor Prof. Thomas Niendorf for their invaluable contributions to this project. Looking forward to future investigations in this exciting and fruitful joint research!

Our this recent publication in ACS Applied Energy Materials deals with the development of a bifunctional electrocatalyst and a novel anion-exchange quasi-solid-state electrolyte membrane (based on quaternary ammonium group-grafted chitosan) for flexible and rechargeable zinc-air batteries (ZAB). A novel idea of anion engineering of metal oxide catalyst is introduced where fluorine atom is doped onto NiCoO2 lattice thereby enhancing its oxygen catalytic activity. On a similar note, a novel anion-conducting polymer electrolyte membrane was developed by quaternising the chitosan membrane yielding a superior polymer electrolyte depicting superior ionic conductivity and mechanical properties. The realistic application of the developed electrocatalyst and the polymer electrolyte membrane was demonstrated in rechargeable ZAB prototypes (RZABs), notably in flexible configurations (f-RZABs).

*****New Publication Alert ***** New paper in the American Chemical Society’s #ACSEnergyLetters journal. “Electron-Donating or -Withdrawing Groups of Carbonate Solvent on Lithium-Ion (De-)intercalation Chemistry”. Cyclic carbonate solvents have been extensively utilized as cosolvents and/or additives in formulating electrolytes for lithium-ion batteries. However, their application often relies on empirical knowledge, lacking a universally applicable perspective to elucidate how different functional groups in cyclic carbonates affect battery performance. Herein, by focusing on the substituted functional group at the α-H in the ethylene carbonate (EC) solvent, it is discovered that solvents containing electron-withdrawing groups (e.g., −F) enable reversible Li+ (de)intercalation in graphite electrodes, while those with electron-donating groups (e.g., −CH3, −CH2CH3) may lead to Li+-solvent co-intercalation. Furthermore, solvents with electron-withdrawing groups can help the electron-donating groups achieve Li+ (de)intercalation, whereas the reverse is not feasible. These phenomena are elucidated through intermolecular interactions, characterized by 2D 1H–19F heteronuclear Overhauser enhancement spectroscopy, revealing interactions between electron-withdrawing and -donating groups in the electrolyte solvation structure. This study offers insights into the roles of electron-donating or -withdrawing groups in electrolyte formulations. https://lnkd.in/g2fKCjip Stay tuned for more exciting news from the School of Physical Sciences at Jawaharlal Nehru University, New Delhi, India. #SPS #JNU #SPSJNU #LiionBattery #Cathode #Anode #Electrolyte #ElectrolyteAdditives #ElectrolyteMicrostructures #Cycliccarbonatesolvents #InterMolecularInteraction #electrondonating #electronwithdrawinggroups #EnergyStorage #Batteries #heteronuclearOverhauserenhancementspectroscopy #desolvationkinetics #solventsolventinteractions #Lisolventanioninteractions #ElectrolyteSolvationChemistry #InterfacialModel #ACS #AmericanChemicalSociety #ACSEnergyLetters Jawaharlal Nehru University Dr. Prashant Tripathi Avinash Rundla Divya Rani Raghuvanshi Shivani Bharti Priyanka .

PAPER REPRISE: Model Estimated Safe Exposure Limits for Engineered Nanoparticles My student Vignesh Ramchandran and I made an effort in this 2023 paper to estimate the NOAEL (No Observed Adverse Effect Level) for groups of engineered nanoparticles (https://lnkd.in/eJHbqj73). The NOAEL is the highest dose of an exposure that produces no detectable negative effect in the subject (usually rodents). It is the basis for setting safe exposure limits for people, where it is usually reduced by a factor of between 10 and 100 due to humans’ longer lifespans and other factors. Interestingly, we identified clusters of nanoparticles that displayed similar combinations of effects with a regression tree model, and estimated NOAELs between 20 and 16,000 micrograms/kilogram for 8 clusters of metal oxide nanoparticles. Uncertainty remains an issue given the data available at the time, but seeing several orders of magnitude difference from one cluster to the next suggests that we might not want to treat all these nano-substances as the same thing when creating regulatory limits. via WordPress https://ift.tt/V5NxEXL October 24, 2024 at 04:03PM

AM Friends, See below a very interesting open-access paper from Linköpings universitet on process monitoring of the Electron Beam Powder Bed Fusion process. It has been known for some years that electrons backscattered from the powder bed can be used to create images of the consolidated powder layer. The images have usually been recorded during a separate beam scanning pattern after the layer has been fully melted. In this paper, the Linköping team has taken electron detection one step further. They demonstrate how real-time electron detection at microsecond level during melting can be used to interpret the status of the melt pool. This is very interesting since it opens up for better process control and faster development of new materials for E-PBF. Of course, I am proud that this groundbreaking work was carried out in an E-PBF machine from Freemelt AB. Our Freemelt ONE research system is the perfect tool for this type of work, thanks to its open architecture. #additivemanufacturing #3dprinting #epbf #freemelt
