Summary: Construction of S-scheme heterojunctions and increasing the specific surface area are effective strategies to enhance photocatalytic performance. In this work, ZnO and ZnO/CeO2 with inverse opal structure were constructed, and a simple UV photoreduction method was used to construct Ag/ZnO/CeO2 photocatalysts. The composite exhibited good photostability and the highest removal efficiency for rhodamine B compared with other structures. The synergetic effect and surface plasmon resonance of Ag nanoparticles contributed to the improved photocatalytic activity. This work provides a new strategy for ZnO-based composites in degrading wastewater pollution.

Summary: A highly sensitive and reproducible multiplex mycotoxin SERS array has been established based on gold nanoparticles (AuNPs)-loaded inverse opal silica photonic crystal microsphere (SIPCM). This method, utilizing the competition immunoassay principle and three different Raman nanotags on SIPCM, shows wide linear detection ranges and low limits of detection for ochratoxin A (OTA), fumonisin B-1 (FB1), and deoxynivalenol (DON), with recovery rates comparable to the classical ELISA method. The SERS-based method exhibits advantages over fluorescence label or enzyme catalytic chemiluminescence methods, and has great potential in rapidly screening multiplex mycotoxins in real samples.

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.

The deterioration mechanisms of the battery at different temperatures are analyzed through various characterization techniques. The results indicate that the battery performance deteriorates more significantly at a low-temperature environment of 5 degrees C compared to higher temperatures. The understanding of the deterioration mechanisms can contribute to the development of safer battery usage methods.

Summary: The use of Lithium-Ion Batteries (LIBs) is becoming increasingly extensive, and it is important to optimize the devices to achieve their maximum practical specific capacity. In this study, mixed ionic-electronic conducting (MIEC) binders based on PEDOT:PSS and PEDOT: PDADMA-TFSI were developed for Li-ion cathodes, and their performance was compared with conventional formulations. The influence of electrode formulations, including the addition of conducting carbon and an Organic Ionic Plastic Cristal (OIPC), was also analyzed. The proposed binders showed improved performance compared to conventional formulations with different electrolyte types and active materials.
