Summary: Layered LaNi0.6Fe0.4O3-delta (LNFO) was prepared via a modified sol-gel method using a carbon nanotube dispersion for pore formation. The prepared LNFO had expanded specific surface area and uniform pores, exhibiting superior electrochemical performance compared to bulk-LNFO prepared by conventional synthesis method. The catalyst stability was demonstrated through chronoamperometric test for over 7200 s.

Summary: Two-dimensional (2D) material heterostructures have attracted attention due to their unique physical properties and potential applications in optoelectronics, photovoltaics, and nanoelectronics. In this study, we developed a fast transfer process using poly(dimethylsiloxane) (PDMS) and micron-sized water droplets to assemble a vertical WS2/Bi2Se3 heterostructure. The heterostructure, with complementary band gaps and efficient interfacial charge transfer, exhibited superior responsivity in photodetection. Our transfer method not only demonstrated time efficiency, but also ensured high quality of the heterointerface, opening pathways for fast and massive fabrication of various vertical 2D heterostructures.

Summary: This study proposes a strategy to develop high-performance bone cement and establishes 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 adjusting the pH of the system, the magnesium-to-phosphate ratio can manipulate the components of hydration products and their transformation, as well as influence the hydration speed and regulate the properties of TMPC. Moreover, TMPC shows outstanding biocompatibility and bone-filling capacity, making it a potential alternative to current bone cements.

Summary: A facile strategy was proposed to prepare Mo-precursor by coordinating Mo with polysaccharide from natural biomass (jujube) at room temperature. The carbonized Mo-polysaccharide complex resulted in highly dispersed Mo2C nanoparticles on an N-doped carbon matrix. The 2D carbon nanosheets-embedded Mo2C NPs showed excellent electrocatalytic performance for the hydrogen evolution reaction in an alkaline medium.
