Summary: Wastewater treatment is crucial due to the potential shortage of drinking water worldwide. This study introduces a new adsorbent called ZnOS+C, which effectively removes FG dye from wastewater. The results indicate that ZnOS+C has a high adsorption capacity and operates under a wide range of pH levels. The adsorption process follows a multilayered model and the kinetics are best described by the intraparticle diffusion model.

Summary: Postoperative cognitive dysfunction (POCD) refers to a decline in cognitive function in aged patients after surgery, with unclear pathological mechanisms. The overexpression of the P2X4 receptor in the central nervous system (CNS) has been associated with the onset of POCD. This study explored the potential of the food dye FGF to prevent POCD by down-regulating the CNS P2X4 receptor. The results showed that FGF significantly attenuated cognitive impairments, decreased P2X4 receptor expression, and inhibited neuroinflammation, suggesting that FGF may be a potential treatment for POCD.

Summary: Ultra-thin nanosheets of two Aurivillius oxides, BWO and BMO, were synthesized and a new procedure for efficient photocatalytic BMO nanosheets was developed. Both BWO and BMO demonstrated effective degradation of the water pollutant dye MG, with BMO showing higher removal rates and stability. Additionally, adsorption contributed to MG removal differently for the two photocatalysts, indicating distinct degradation mechanisms.

Summary: A fast-relaxation dye-doped cholesteric liquid crystal (DDCLC) smart window without any defects is prepared by doping CB7CB, a liquid crystal dimer with low bend elastic constants. By adjusting the ratio of bend elastic constant to twist elastic constant to unity, the relaxation time from the homeotropic state to the planar state is greatly reduced. The oily streaks of the planar state are removed and light scattering is lessened.

Summary: In this study, lignocellulosic biosorbents in fiber form were prepared from lemongrass leaf through a simple and green process. The most suitable fibrous biosorbent for dye adsorption was found to be TLGL5 treated with 5% NaOH, showing maximum adsorption capacities towards crystal violet and methylene blue. The thermodynamic study indicated a spontaneous and endothermic adsorption reaction for both dyes, and TLGL5 showed good potential for multiple adsorption-desorption cycles.

Summary: This study investigated the biosorption properties of cranberry kernel biomass for fast green FCF dye in aqueous solution. The optimal conditions for biosorption were determined to be a natural pH of 6.0, a temperature of 25 degrees C, and a dye concentration of 500 mg L-1. The Langmuir isotherm model showed a maximum biosorption capacity of 21.6 mg g(-1) for the cranberry kernel biomass. The biosorption process was found to be spontaneous, entropy-increasing, and endothermic. The results indicated that cranberry kernel biomass is a natural, abundant, low-cost, effective, and potential biosorbent for the removal of fast green FCF dye from wastewater.

Summary: A series of environmentally friendly photoinitiating systems (VisPIs) based on water soluble xanthene dyes were tested for vinyl polymerization using sunlight as a radiation source. The Vis-PIs showed good performances, obtaining colorless polymers with high yields after short irradiation times. Surprisingly, the Vis-PIs also worked successfully under ambient air atmosphere. The report represents a breakthrough in the search for fast, efficient and inexpensive green Vis-PIs for outdoor coating applications.
