    Computational materials discovery and development for Li and non-Li advanced battery chemistries
    (International Association of Physical Chemists, 2023) Sharma, H.; Nazir, A.; Kasbe, A.; Kekarjawlekar, P.; Chatterjee, K.; Motevalian, S.; Claus, A.; Prakash, V.; Acharya, S.; Sahu, K.K.
    Since the discovery of batteries in the 1800s, their fascinating physical and chemical properties have led to much research on their synthesis and manufacturing. Though lithium-ion batteries have been crucial for civilization, they can still not meet all the growing demands for energy storage because of the geographical distribution of lithium resources and the intrinsic limitations in the cell energy density, performance, and reliability issues. As a result, non-Li-ion batteries are becoming increasingly popular alternatives. Designing novel materials with desired properties is crucial for a quicker transition to the green energy ecosystem. Na, K, Mg, Zn, Al ion, etc. batteries are considered the most alluring and promising. This article covers all these Li, non-Li, and metal-air cell chemistries. Recently, computational screening has proven to be an effective tool to accelerate the discovery of active materials for all these cell types. First-principles methods such as density functional theory, molecular dynamics, and Monte Carlo simulations have become established techniques for the preliminary, theoretical analysis of battery systems. These computational methods generate a wealth of data that might be immensely useful in the training and validating of artificial intelligence and machine learning techniques to reduce the time and capital expenditure needed for discovering advanced materials and final product development. This review aims to summarize the application of these techniques and the recent developments in computational methods to discover and develop advanced battery chemistries. © 2023 by the authors; licensee IAPC, Zagreb, Croatia.

    Fundamental physics opportunities with future ground-based mm/sub-mm VLBI arrays
    (Springer Science and Business Media Deutschland GmbH, 2025) Ayzenberg, D.; Blackburn, L.; Brito, R.; Britzen, S.; Broderick, A.E.; Carballo-Rubio, R.; Cardoso, V.; Chael, A.; Chatterjee, K.; Chen, Y.; Cunha, P.V.P.; Davoudiasl, H.; Denton, P.B.; Doeleman, S.S.; Eichhorn, A.; Eubanks, M.; Fang, Y.; Foschi, A.; Fromm, C.M.; Galison, P.; Ghosh, S.G.; Gold, R.; Gurvits, L.I.; Hadar, S.; Held, A.; Houston, J.; Hu, Y.; Johnson, M.D.; Kocherlakota, P.; Natarajan, P.; Olivares Sánchez, H.; Palumbo, D.; Pesce, D.W.; Rajendran, S.; Roy, R.; Saurabh; Shao, L.; Tahura, S.; Tamar, A.; Tiede, P.; Vincent, F.H.; Visinelli, L.; Wang, Z.; Wielgus, M.; Xue, X.; Yakut, K.; Yang, H.; Younsi, Z.
    The Event Horizon Telescope (EHT) Collaboration recently published the first images of the supermassive black holes in the cores of the Messier 87 and Milky Way galaxies. These observations have provided a new means to study supermassive black holes and probe physical processes occurring in the strong-field regime. We review the prospects of future observations and theoretical studies of supermassive black hole systems. Current ground-based very-long-baseline interferometry (VLBI) arrays like the EHT and proposed future extensions like the next-generation Event Horizon Telescope will greatly enhance the capabilities of black-hole imaging interferometry. These enhancements will open up several previously inaccessible avenues of investigation, thereby providing important new insights into the properties of supermassive black holes and their environments. This review describes the current state of knowledge for five key science cases, summarising the unique challenges and opportunities for fundamental physics investigations that future mm/sub-mm VLBI developments will enable. © The Author(s) 2025.
