The development of efficient, durable, and cost-effective oxygen evolution reaction (OER) electrocatalysts is essential for advancing renewable energy technologies. Herein, a novel strategy is reported that spatially confines a nanoscale localized high-entropy oxide (LHEO) consisting of Fe, Co, Ni, Zn, and Mn within α-Fe2O3, forming a unique α-Fe2O3@LHEO nanoarchitecture. The catalyst exhibits outstanding OER performance for alkaline water splitting, achieving a current density of 10 mA/cm2 at a low overpotential of 229 mV with a small Tafel slope of 34.4 mV/dec, significantly outperforming commercial RuO2 (326 mV, 118.8 mV/dec). It also shows excellent long-term stability over 1000 h at 100 mA/cm2 without notable activity degradation. Applied in rechargeable zinc–air batteries with natural seawater, the α-Fe2O3@LHEO cathode delivers a high power density of 88.3 mW/cm2 and stable operation over 600 cycles, substantially surpassing the benchmark Ru-Pt electrocatalyst (74.7 mW/cm2, 170 cycles). Combined experimental and theoretical studies reveal that LHEO induces lattice strain in α-Fe2O3, modulates its electronic structure, and lowers the crystal field splitting energy to stabilize high-spin Fe3+. These effects enhance metallic character for efficient charge transfer and optimize the adsorption/desorption of key oxygen reaction intermediates, thus shifting the OER pathway from the conventional adsorbate evolution mechanism (AEM) to the more energetically favorable lattice oxygen mechanism (LOM) with the energy barrier reduced from 1.85 to 1.71 eV. Overall, this work proposes a novel localized high-entropy engineering approach that overcomes key bottlenecks in designing efficient and durable OER electrocatalysts based on earth-abundant materials.

A research team at the Faculty of Engineering of The University of Hong Kong (HKU), led by Professor Ruibang Luo from the School of Computing and Data Science and Professor Can Li from the Department of Electrical and Computer Engineering, has developed Gungnir, a novel blockchain-inspired DNA data storage codec. The breakthrough framework significantly improves digital information recovery from severely damaged DNA sequences, extending the practical lifespan of DNA data archives from under a decade to centuries.

In shale reservoirs, total oil content does not necessarily show where oil is stored or how mobile it may be. Researchers led by Bo Liu at Northeast Petroleum University developed a multiscale workflow that combines swelling-extraction experiments, SEM/AFM pore characterization and molecular dynamics simulations. The study separates shale oil into five occurrence types: kerogen-swelling oil, adsorbed oil in organic pores, free oil in organic pores, adsorbed oil in inorganic pores and free oil in inorganic pores. The framework offers a tool with strong applicability across study areas for understanding oil-rock interactions and evaluating shale-oil mobility in continental shale systems.

Researchers at the Max Planck Institute for Intelligent Systems and Carnegie Mellon University have unveiled a breakthrough technology that allows for highly accurate 3D motion capture using only standard video cameras, eliminating the need for expensive, specialized hardware and the iconic skin-tight motion capture suits covered in reflective markers. They named their system MAMMA – Markerless Accurate Multi-person Motion Acquisition. This system is capable of accurately capturing human motion without the need for markers, making it easy and cheap for everyone to create high-end animations and virtual avatars.
