Summary: By coating ordered mesoporous Mn2O3 (m-Mn2O3) and highly conductive Super P (SP) on polyethylene (PE) separators, we have designed a multifunctional composite separator to enhance the reversibility and cycling stability of lithium-sulfur batteries (LSBs). The m-Mn2O3 offers fast chemisorption of polysulfides dissolved in electrolyte, and the highly conductive SP physically mitigates the crossover of polysulfides and reversibly reutilizes them during cycling. In practice, the LSB cell assembled with the separator coated with m-Mn2O3 and SP delivers a high reversible capacity of 553 mAh g-1 at a current density of 0.5 C, even after 300 cycles.

Summary: This study presents the synthesis of tin selenide nanoparticles grown on highly conductive, porous 3D graphene foam as a stable host for sodium metal anodes and reveals their energy storage mechanism through conversion reactions. The SnSe@GF electrode exhibits remarkable reversibility after 1500 cycles in asymmetric cells and extraordinary cyclic stability and low overpotentials for 2000 h in symmetric cells. The outstanding performance is attributed to the conversion of crystalline SnSe into low-crystallinity Na15Sn4 and Na2Se dual nucleation sites after pre-sodiation, which enables the formation of a unique interface with high sodium affinity and abundant active sites, resulting in uniform sodium nucleation/plating and dendrite suppression.

Summary: This study provides the first evidence for the transcriptional and functional characterization of PRSS3 transcripts in HCC. Aberrant expression of divergent PRSS3 splice variants disrupted by site-specific CpG methylation may integrate the effects of oncogenic PRSS3-V2 and tumor-suppressive PRSS3-V1, resulting in the molecular diversity and functional plasticity of PRSS3 in HCC. Dysregulated expression of PRSS3-V2 by site-specific CpG methylation may have potential diagnostic value for patients with early HCC.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.
