Local phase transition in transition metal dichalcogenides (TMDCs) by lithiumintercalation enables the fabrication of high-quality contact interfaces in twodimensional(2D) electronic devices. However, controlling the intercalation oflithium is hitherto challenging in vertically stacked van der Waalsheterostructures (vdWHs) due to the random diffusion of lithium ions in thehetero-interface, which hinders their application for contact engineering of 2DvdWHs devices. Herein, a strategy to restrict the lithium intercalation pathwayin vdWHs is developed by using surface-permeation assisted intercalationwhile sealing all edges, based on which a high-performance edge-contact MoS_(2)vdWHs floating-gate transistor is demonstrated. Our method avoids intercalationfrom edges that are prone to be random but intentionally promotes lithiumintercalation from the top surface. The derived MoS_(2) floating-gatetransistor exhibits improved interface quality and significantly reduced subthresholdswing (SS) from >600 to 100 mV dec^(–1). In addition, ultrafast program/erase performance together with well-distinguished 32 memory statesare demonstrated, making it a promising candidate for low-power artificialsynapses. The study on controlling the lithium intercalation pathways in 2DvdWHs offers a viable route toward high-performance 2D electronics for memoryand neuromorphic computing purposes.

Effect of Al on the sealing performance of Al-Al2O3 composite materials for intermediate temperature planar SOFC application

To satisfy the requirements of planar solid oxide fuel cell (SOFC) in reliable gas tightness for the separation of fuel and oxidant, Al-Al2O3 composite seals with various Al amounts of 10–30 wt% are fabricated in this work and afterwards, effect of Al on their thermal expansion behavior and gas leakage rate are investigated at different temperatures. It is demonstrated that the presented Al-Al2O3 composite seal containing 15 wt% Al (denoted as A15) exhibits a low gas leakage rate of 0.021 sccm cm−1 under input gas pressure of 20.7 kPa between 650 °C and 800 °C. Further studies show that stable leakage rates can be maintained below 0.027 sccm cm−1 after enduring 10 thermal cycles or holding for 100 h test at 750 °C, revealing that a small amount of Al addition could significantly improve the sealing performance and thermal cycle stability of Al-Al2O3 composite seal. XRD and SEM results suggest that A15 has excellent structural stability and interfacial chemical compatibility, which can be attributed to the continuous oxidation of Al powders blocking the leakage paths and the formation of the well bonding interface between interconnect/seal/cell anode. It is also found that the open circuit voltage (OCV) of 1-cell stack is 1.13 V at 750 °C for 100 h and undetectable voltage degradation are observed which means the A15 composite seal has excellent gas tightness for 1-cell stack. The experimental results confirm the promising potential of Al-Al2O3 composite seal in SOFC application, which provides a new direction for the development of high performance seal material in the future. © 2025 Elsevier Ltd and Techna Group S.r.l.

Magnesium phosphate bone cement has become a widely used orthopedic implant due to the advantages of fast-setting and high early strength. However, developing magnesium phosphate cement possessing applicable injectability, high strength, and biocompatibility simultaneously remains a significant challenge. Herein, we propose a strategy to develop high-performance bone cement and establish a trimagnesium phosphate cement (TMPC) system. The TMPC exhibits high early strength, low curing temperature, neutral pH, and excellent injectability, overcoming the critical limitations of recently studied magnesium phosphate cement. By monitoring the hydration pH value and electroconductivity, we demonstrate that the magnesium-to-phosphate ratio could manipulate the components of hydration products and their transformation by adjusting the pH of the system, which will influence the hydration speed. Further, the ratio could regulate the hydration network and the properties of TMPC. Moreover, in vitro studies show that TMPC has outstanding biocompatibility and bone-filling capacity. The facile preparation properties and these advantages of TMPC render it a potential clinical alternative to polymethylmethacrylate and calcium phosphate bone cement. This study will contribute to the rational design of high-performance bone cement.

Commercial application of lithium-sulfur(Li-S) batteries is hindered by the insulating nature of sulfur and the dissolution of polysulfides. Here, a bioinspired 3D urchin-like N-doped Murray's carbon nanostructure(N-MCN) with interconnected micro-meso-macroporous structure and a polydopamine protection shell has been designed as an effective sulfur host for high-performance Li-S batteries. The advanced 3D hierarchically porous framework with the characteristics of the generalized Murray's law largely improves electrolyte diffusion, facilitates electrons/ions transfer and provides strong chemisorption for active species, leading to the synergistic structural and chemical confinement of polysulfides. As a result,the obtained P@S/N-MCN electrode with high areal sulfur loading demonstrates high capacity at high current densities after long cycles. This work reveals that following the generalized Murray's law is feasible to design high-performance sulfur cathode materials for potentially practical Li-S battery applications.
