Summary: This study proposes a controlled strategy to optimize the photocatalytic performance of hybrid catalysts by introducing organic components. The enhanced photocatalytic activity of P-FGDY/TiO2 compared to FGDY/TiO2 is attributed to the regulation of FGDY, which increases the efficiency of photogenerated electron and hole separation. This work provides a novel regulating pathway to optimize the photocatalytic activity of carbon-based hybrid photocatalysis material systems.

Summary: The study successfully fabricated a UV protection additive, 1,6-hexanediamine modified layered zinc phenylphosphonate (m-PPZn), for acrylic acid-grafted poly(butylene carbonate-co-terephthalate) (g-PBCT). The g-PBCT polymer matrix was intercalated into the interlayer spacing of m-PPZn, which showed enhanced UV protection ability compared to the pure g-PBCT polymer matrix. The results indicated that the g-PBCT/m-PPZn composites had lower carbonyl index and molecular weight after photodegradation, owing to the better UV reflection ability of m-PPZn.

Summary: The study compared the light yield achieved in two liquid argon chambers equipped with PEN and TPB wavelength shifters, with the PEN chamber's yield being 39.4% of the TPB chamber's. Utilizing Monte Carlo simulation, the efficiency of PEN relative to TPB for wavelength shifting was determined to be 47.2%. This suggests that using readily available PEN foils as a wavelength shifter can streamline the construction of future liquid argon detectors.

Summary: In this study, sulfur is incorporated into the polymer chain by chemical polymerization to obtain C3N3S3. Unlike g-C3N4, C3N3S3 does not exist in the form of a graphitic structure and cannot be exfoliated into thin lamellas. However, both polymers have similar optical properties and positions of the conduction and valence bands. Comparative studies show that C3N3S3 exhibits smaller overpotentials for electrochemical oxygen reduction and hydrogen evolution compared to g-C3N4. Additionally, spectroscopic experiments demonstrate that both polymers have high activity in the photocatalytic reduction of oxygen to superoxide anion radical by the photogenerated electrons.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
