Layered sodium manganese oxides (Na_2/3MnO₂) are promising cathode materials for developing high-capacity sodium-ion batteries. However, they suffer from severe capacity fading during cycling. In a new study, researchers systematically investigated how scandium doping can improve the cycling stability of P’2 polytype of Na_2/3MnO₂, revealing a new design strategy for developing long-life and high-capacity sodium-ion batteries for commercial applications.

Time division multiplexing (TDM) architecture is an important approach to creating sensor arrays for massive scale monitoring. But it is paradoxical for the TDM interferometric sensor array to keep a short delay fiber for high sensing resolution and meanwhile use low sampling rate for practical applications. In this paper, a phase matching sampling (PMS) paradigm is proposed to address the above contradiction.

This study shows how the interplay of ink composition and printing design shapes the structure, strength, and bioactivity of 3D-printed bone implants. By adjusting these factors, researchers achieved implants that better guide bone cell growth while maintaining stability, advancing personalized treatment for bone repair.

Seoul National University College of Engineering announced that a joint research team led by Prof. Yong-Seok Hwang from the Department of Nuclear Engineering, in collaboration with the Asia Pacific Center for Theoretical Physics (APCTP), has experimentally demonstrated the phenomenon of multiscale coupling in plasma—a long-standing puzzle in plasma physics—through the integration of fusion experiments and astrophysical plasma theory.

Researchers have utilized polymer zwitterions incorporating conjugated units to modify inorganic metal oxide (zinc oxide, ZnO) interlayers in organic solar cells. This approach effectively passivates defects, improves charge extraction and transport, and consequently enhances device performance. Furthermore, the conjugated units absorb ultraviolet radiation and protect the organic semiconductor layers, contributing to enhanced device stability.
