In summary, this review provides a comprehensive picture of how low-dimensional perovskite materials could revolutionize memory devices and computing, which is expected to inspire new ideas and discussions in the near future.

Seoul National University College of Engineering announced that Professor Jong-Ho Lee's research team from the Department of Electrical and Computer Engineering has developed a groundbreaking new hardware security technology based on commercially available 3D NAND flash memory (V-NAND flash memory).

Named "Concealable Physical Unclonable Function (Concealable PUF)," this technology maintains the core advantages of conventional PUFs—unclonability and randomness—while adding a novel feature: the ability to hide the security key and reveal it only when needed. This marks the world's first implementation of such functionality on V-NAND flash memory.

The study was published online on June 3 in Nature Communications, one of the most prestigious scientific journals.

As environmental pollutants pose a serious threat to socioeconomic and environmental health, the development of simple, efficient, accurate and cost-effective methods for pollution monitoring and control remains a major challenge, but it is an unavoidable issue. In the past decade, the artificial nanozymes have been widely used for environmental pollutant monitoring and control, because of their low cost, high stability, easy mass production, etc. However, the conventional nanozyme technology faces significant challenges in terms of difficulty in regulating the exposed crystal surface, complex composition, low catalytic activity, etc. In contrast, the emerging single-atom nanozymes (SANs) have attracted much attention in the field of environmental monitoring and control, due to their multiple advantages of atomically dispersed active sites, high atom utilization efficiency, tunable coordination environment, etc. To date, the insufficient efforts have been made to comprehensively characterize the applications of SANs in the monitoring and control of environmental pollutants. Building on the recent advances in the field, this review systematically summarizes the main synthesis methods of SANs and highlights their advances in the monitoring and control of environmental pollutants. Finally, we critically evaluate the limitations and challenges of SANs, and provide the insights into their future prospects for the monitoring and control of environmental pollutants.

Manganese-based chalcogenides have significant potential as anodes for sodium-ion batteries (SIBs) due to their high theoretical specific capacity, abundant natural reserves, and environmental friendliness. However, their application is hindered by poor cycling stability, resulting from severe volume changes during cycling and slow reaction kinetics due to their complex crystal structure. Here, an efficient and straightforward strategy was employed to in-situ encapsulate single-phase porous nanocubic MnS_0.5Se_0.5 into carbon nanofibers using electrospinning and the hard template method, thus forming a necklace-like porous MnS_0.5Se_0.5-carbon nanofiber composite (MnS_0.5Se_0.5@N-CNF). The introduction of Se significantly impacts both the composition and microstructure of MnS_0.5Se_0.5, including lattice distortion that generates additional defects, optimization of chemical bonds, and a nano-spatially confined design. In situ/ex-situ characterization and density functional theory calculations verified that this MnS_0.5Se_0.5@N-CNF alleviates the volume expansion and facilitates the transfer of Na⁺/electron. As expected, MnS_0.5Se_0.5@N-CNF anode demonstrates excellent sodium storage performance, characterized by high initial Coulombic efficiency (90.8%), high-rate capability (370.5 mAh g^-1 at 10 A g^-1) and long durability (over 5000 cycles at 5 A g^-1). The MnS_0.5Se_0.5@N-CNF//NVP@C full cell, assembled with MnS_0.5Se_0.5@N-CNF as anode and Na₃V₂(PO₄)₃@C as cathode, exhibits a high energy density of 254 Wh kg^-1 can be provided. This work presents a novel strategy to optimize the design of anode materials through structural engineering and Se substitution, while also elucidating the underlying reaction mechanisms.
