Summary: Zwitterionic gemini surfactants were synthesized and used to modify Na-vermiculite, resulting in efficient adsorbents for the removal of Congo red. The modified organo-vermiculites showed resistance to pH change but were greatly affected by temperature. The adsorption process was found to fit well with pseudo-second kinetic model and Freundlich isotherm model. The functional groups and long alkyl chains in the surfactants played important roles in promoting the adsorption of Congo red. This study provides insights into the mechanism and application of zwitterionic gemini surfactants in wastewater treatment.

Summary: The GAF3 domain of the cyanobacteriochrome Slr1393 can undergo photochromicity and be used for photoacoustic imaging. The light-modulatable photoacoustic waveforms arising from GAF3 can be distinguished from background signals originating from non-modulatable competitive absorbers and scattering media. This effect was verified using a phantom filled with either GAF3 or E.coli overexpressing GAF3.

Summary: In this study, two types of epoxy resins, bisphenol A-type epoxy (ER) and epoxy phenol novolac resins (EPN), were chosen with two different amine-type curing agents. The mechanical properties and density of EPN resin were higher when using both curing agents. EPN was modified with polystyrene (EPN-PS) and used as a matrix with an IPOX hardener. Nano- and hybrid composites were prepared with pristine and modified montmorillonite and red mud waste. The appropriate ratios of PS and NC were 4% and 2%, respectively. The curing degrees of ER, EPN, and EPN-PS were 99.3%, 99.9%, and 86.5%, respectively. The appropriate ratio of RMW was 30 wt%. Hybrid composites with 25-30 wt% RMW can be considered self-extinguishing materials.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
