Summary: This study focuses on the formulation and characterization of oil-in-water Pluronic F127 microemulsions to enhance the bioavailability of doxorubicin (DOX). The interaction details of DOX with ethyl butyrate, sodium caprylate, and Pluronic F127 were investigated using density functional theory calculations. The experimental results show that Pluronic F127/DOX microemulsions induce morphological changes and have stronger cytotoxic effects compared to standard DOX.

Summary: By studying the stability of PLGA nanoparticles (PNPs) in F127 hydrogels, it was found that flocculation and deposition of PNPs in F127 hydrogels is dependent on the type of emulsifier, particle materials, and F127 concentration. The flocculated PNPs can be restored to their original state after washing with water. This study provides theoretical and experimental support for the rational design and development of nanoparticle-hydrogel composites.

Summary: We investigated the effects of confinement imposed by poly(ethylene glycol) (PEG) hydrogel matrices on the dynamics of soft microgels through characterization of the internal structure. The microgel dynamics slowed down and changed from diffusive to sub-diffusive due to increasing confinement. The decrease in diffusivity can be attributed to hydrodynamic and steric effects in addition to the geometrical constriction of cylindrical pores. The dependence of the effective diffusion coefficient on the pore volume fraction suggests the presence of microgel-hydrogel interactions.

Summary: Solvothermal synthesis of mesoporous materials based on amphiphilic molecules as structure-directing agents can be enhanced using non-conventional technologies for stirring and thermal activation. Here, we disclose a green synthesis approach for the preparation of cerium-modified hexagonally ordered silica sieves. Ultrasound micromixing enabled us to obtain well-dispersed Ce in the self-assembled silica network and yielded ordered materials with high cerium content (Ce/Si molar ratio = 0.08). Microwave dielectric heating, applied by an innovative open-end coaxial antenna, was used to reduce the overall hydrothermal synthesis time and to improve the surface area and textural properties. These mesoporous materials were used as a Ni catalyst support (10 wt.% metal loading) for the ethanol steam reforming reaction. The new catalysts featured complete ethanol conversion, high H-2 selectivity (65%) and better stability, compared to the same catalyst prepared with magnetic stirring and conventional heating. The Ce-promoted silica sieves offered a suitable support for the controlled growth of nanocarbon that does not result in catalyst deactivation or poisoning after 6 h on stream.

Summary: Solutions of weakly coordinating ionic liquids (ILs) in alkyl carbonates have attracted attention due to their green solvents properties, but the understanding of ILs' phase behavior and structure in organic polar solvents is lacking. This study investigates the interactions and nanoscale structure of a specific IL, [BMIm][BARF], in alkyl carbonate solvents. The results show that [BMIm][BARF] is mostly undissociated in these solvents and the presence of rod-like nanostructures in the IL/solvent mixtures. The study also reveals that the self-assembly of nano-sized structures is hindered by slower ion diffusion in alkyl carbonates with lower dielectric constants. The findings have implications in various fields including batteries, catalysis, extraction, and bio-applications.

Summary: Calciprotein particles (CPPs) are colloidal hybrid particles formed in serum, consisting of amorphous calcium phosphate stabilized by fetuin-A protein. This study found that albumin, although abundant in serum, cannot prolong the lifetime of the amorphous phase of CPPs. However, albumin is effective in delaying the sedimentation of CPPs after crystallization and significantly decreases the amount and size of CPPs when present in their synthetic medium, playing a crucial role in the stabilization of CPPs.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
