Summary: This study demonstrates a method to efficiently encapsulate curcumin into silica particles using CTAB micelles, which improves the dispersing ability and stability of curcumin in aqueous media. The emission properties of curcumin depend on the structure of CTAB micelles embedded in the silica particles, with quasi-crystalline micelles being sensitive to pH changes and amorphous micelles being less sensitive. Further incorporation of a green emissive dye allows for visualized detection of pH using these curcumin-doped silica particles.

Summary: The influence of CTAB micelles and ammonia on the dispersing and stability of curcumin in ethanol/water mixture was investigated in this study. It was found that CTAB could promote dispersing of Cur at low ammonia concentration and facilitate the conversion of Cur species at high ammonia concentration. The in-situ preparation of Cur doped silica particles was achieved using optimized concentrations of ammonia and CTAB, leading to improved responsiveness towards Cu2+.

Summary: This study demonstrates that the adsorption of solid particles on the surface of solubilizing oil droplets can significantly increase the droplets' self-propulsion speeds, with the highest speeds achieved at around 40% particle surface coverage. The addition of silica particles to oil-water interfaces provides a straightforward way to tune active droplet dynamics, showing the broad impact of this effect in different surfactants and oil droplet compositions.

Summary: In this study, 3Mg(OH)(2)center dot MgCl2 center dot 8H(2)O (318MHCH) nanowires with ultra-high aspect ratios were synthesized using a liquid method. The effects of cetyltrimethylammonium bromide (CTAB) in highly concentrated salt solution were investigated. The introduction of CTAB significantly increased the aspect ratio of 318MHCH nanowires from 500 to 4000.

Summary: The study investigates the effect of using DDAA and CTAB as a mixed collector on the flotation separation of diaspore and kaolinite. The experimental results show that the use of DDAA and CTAB significantly improves the flotation separation performance of diaspore and kaolinite. The adsorption analysis and molecular dynamics simulation support the experimental findings, showing that the interaction energies between DDAA and diaspore are more negative, while the interaction energies between CTAB and kaolinite are also more negative. The theoretical calculations and experimental results indicate that the enlarged difference in adsorption amounts is beneficial for the flotation separation performance of minerals.

Summary: Traditional research methods for the biodegradation of emerging organic pollutants are slow and labor-intensive, but new metagenome, metatranscriptome, and metabolome technologies offer a faster and more efficient approach. By integrating these three "omics" approaches, it is possible to link gene abundance and expression with the biotransformation of the pollutants and the formation of metabolites. In this study, the tri-omics approach was used to study the biotransformation pathways of cetyltrimethylammonium bromide (CTAB) under aerobic conditions. The analysis revealed three parallel first-step oxygenation pathways and identified key intermediates and enzymes involved in the biotransformation of CTAB. This study highlights the potential of the tri-omics approach for future research on complex organic biodegradation by microbial communities.

Summary: Osteoporosis is a disorder characterized by bone loss and impaired bone regeneration. Curcumin (Cur) can promote osteogenesis but has limitations in delivery. Tetrahedral framework nucleic acids (tFNAs) are nanomedicines that can bind Cur and regulate cell functions. tFNAs/Cur complexes showed potential in promoting bone repair in osteoporotic rats. tFNAs improve Cur utilization and serve as a promising intervention for osteoporosis.

Summary: In this study, paclitaxel (PTX) and curcumin (Cur) were encapsulated into nanogels (NG-PC) for the synergistic suppression of breast tumors. NG-PC showed controlled and cumulative release of PTX and Cur, as well as a remarkable killing effect against cancer cells. In vivo evaluation on tumor-bearing mice demonstrated that NG-PC had significantly higher antitumor ability compared to a single drug. This research provides a simple method to prepare a nano-drug delivery platform with excellent drug co-loading ability and synergistic antitumor effect.

Summary: An efficient deep eutectic solvent (DES), synthesized using cetyltrimethylammonium bromide (CTAB) and ethylene glycol (EG), was used to enhance enzymatic saccharification of rape straw (RS). The optimized pretreatment parameters showed that the DES selectively removed lignin and xylan while preserving cellulose. DES pretreatment resulted in an increased enzymatic hydrolysis efficiency of RS by 46.0% due to the removal of 62.2% lignin and 53.2% xylan. The study also revealed that DES pretreatment improved cellulosic accessibility, reduced lignin hydrophobicity and surface area, and caused migration of cellulosic crystalline structure, contributing to enhanced enzymatic hydrolysis efficiency. Overall, this study presented an emerging method for the effective fractionation and valorization of lignocellulosic biomass within biorefinery technology.
