A pioneering breakthrough in InP-based quantum dots (QDs) is achieved, realizing the first synergistic regulation of efficient pure blue emission and room-temperature ferromagnetism. This work provides new materials for spintronic devices and offers a novel design framework for the optical and magnetic regulation of III-V QDs, advancing the practical application of cadmium-free semiconductor opto-magnetic integrated devices.

An international research team has found evidence of the existence of an exotic atomic nucleus state in an experiment at the GSI/FAIR research center in Darmstadt. Although such a state has long been predicted theoretically, it has never been observed before. The system consists of an atomic nucleus of the carbon isotope ¹¹C and an η′ meson (etaprime meson) — a short-lived particle composed of a quark and an antiquark. This system is bound exclusively by the strong interaction, i.e., the force that also holds protons and neutrons together in the atomic nucleus.

This study proposes a 3D Cu/Fe3O4 Mott-Schottky nano-tip array, which reconstructs the “tip effect” and synergistically integrates electric and magnetic field regulation to achieve uniform lithium deposition, offering an innovative solution for controlling lithium deposition.

In this study, the long-afterglow material Sr₂MgSi₂O₇:(Eu,Dy) was hybridized with semiconductor CdS to fabricate an S-scheme heterojunction, endowing the resultant Sr₂MgSi₂O₇:(Eu,Dy)/CdS catalyst with integrated long-lasting luminescence and photocatalytic performance. The catalyst enables continuous hydrogen production via catalysis under light/dark alternating conditions. This novel strategy sheds new light on the design and development of round-the-clock photocatalysts, and also provides a valuable reference for realizing efficient and stable continuous hydrogen production.

In this work, researchers addressed a critical challenge in Li-ion battery development: the mechanical degradation and poor cycling stability of silicon-based anodes. Their study seeks to answer whether a scalable, low-cost spray-drying method can effectively integrate graphite fines, nano-silicon, and carbon nanotubes into a composite that mitigates these issues while maintaining high electrochemical performance.

Researchers have developed an integrated gray wolf optimization algorithm-based hybrid estimation framework that combines sample entropy, localized voltage area, and fuzzy entropy to accurately estimate the state of health of bipolar lead-acid batteries. Partial charging profiles are utilized to extract and validate battery health feature attributes based on gray relational grades. The proposed hybrid models utilize two pairs of battery health attributes: localized voltage area paired with either fuzzy entropy or sample entropy. The average mean absolute error and average root mean squared error values are below 1.02 percent and 1.5 percent respectively for the localized voltage area and fuzzy entropy health attribute pair.

As the global push for carbon neutrality accelerates, managing the massive energy demands and waste heat of industrial sectors has become a critical challenge. Industrial energy systems currently account for nearly 40% of global electricity demand growth. To address this, scientists are increasingly turning to a promising long-duration energy storage technology: the Carnot battery.

A composite material with a “reinforced concrete” structure was constructed by using core-shell CF@PANI as the “steel reinforcement” and Fe₃O₄/PDA/Ti₃C₂T_x as the “concrete” matrix through a combined approach involving in-situ polymerization, in-situ mineralization, and electrostatic self-assembly. This material not only exhibits excellent electromagnetic wave absorption performance but also demonstrates significantly enhanced mechanical properties.

Advancing the rapidly growing field of photonic quantum information processing requires novel, highly scalable methods to precisely manipulate complex states of light. Researchers at the Technion, Israel, designed nanophotonic chips that successfully transform the total angular momentum degrees of freedom of a single photon into robust, topologically protected, light patterns known as Quantum Skyrmions. Generating and manipulating skyrmions offers powerful new tools for advanced information processing, paving the way for next-generation, high-dimensional quantum computing capabilities.
