Summary: Controlled buckling of colloidal droplets via acoustic levitation is important in pharmaceutical, coating, and material self-assembly. This study investigated the evaporation process of PTFE colloidal droplets with different particle concentrations under acoustic levitation and observed surface invagination. Higher particle concentration led to invagination on the upper surface, forming a bowl-shaped structure, while lower particle concentration resulted in invagination on both upper and lower surfaces, forming a doughnut-like structure. The hollow cavity on the droplet surface absorbed sound energy and caused positive acoustic radiation pressure, promoting the invagination process.

Summary: This study investigates the correlation between the evaporation dynamics of a gold nanorod dispersion droplet and the formation of a coffee stain with distinct microstructures. The droplet retraction, pinning, and quick evaporation during different drying phases are found to be clearly correlated with the aggregation regions in the coffee stain. The unique assemblies of gold nanorods in the coffee stain edge have the potential to be used for plasmonic sensors, while the large clusters of nanorods outside the stain could enhance the fluorescence of low quantum yield molecules. Controlling the evaporating droplet kinetics can tailor the solute deposition pattern.

Summary: Based on the numerical study, a higher initial nanoparticle concentration leads to larger and more numerous necks, resulting in increased effective thermal conductivity of the NTS. Drying temperature has minimal impact on the effective thermal conductivity of the resultant NTS, but neck size and distribution become more uniform at higher drying temperatures. Decreasing wettability of the cavity's top and bottom surfaces causes necks to shrink or disappear, while the size of necks between filler particles in the middle of the cavity slowly expands, leading to a decrease in the effective thermal conductivity of the NTS.

Summary: Utilizing ultra-short-pulse laser filamentation of glass is a new technique for glass cutting, which has the advantages of small heat-affected zone and quasi-non-gap cut. However, the cleaving process and underlying mechanisms are still not well understood. In this study, a specially designed optic was used to generate laser filamentation in different types of glass, and the filaments and cut edge were analyzed. Based on the observations, models were proposed to describe the micro crack formation caused by laser pulses.

Summary: Carrier-free curcumin nanoparticles (CFC NPs) were prepared by adding the DMSO solution of Cur into DI water under continuous rapid stirring. The CFC NPs exhibited a spherical shape with a diameter of 65.25 +/- 2.09 nm (PDI = 0.229 +/- 0.107) and a high loading capacity (LC) of 96.68 +/- 0.03%. Furthermore, the CFC NPs significantly improved the water dispersibility and release of Cur in vitro, and showed significantly enhanced DPPH radical scavenging activity. These results suggest that CFC NPs could be a promising vehicle for widening the applications of Cur in the food industry.

Summary: In this study, an ex vivo absorption model based on the permeability of the rat small intestine was established to evaluate the intestinal absorption of DHA microcapsules with five formulations after gastrointestinal digestion. The results showed that the permeability of glucose solution increased with concentration, while the absorption rate of DHA microcapsules was low. The absorption rate was also influenced by the release of free fatty acids from the microcapsules.

This study derives an absorption model that considers the 3D intestinal inner wall structure and can be used in a 1D distributed model.

Summary: The large deformation of an elastic hollow ellipsoid was investigated as a flowmeter mechanism. Relationships were found between pressure drop, deformation, flowrate, and fluid viscosity. The experiment used a silicone hollow ellipsoid with dimensions of 0.05 m (long axis), 0.03 m (short axis), and a wall thickness of 3.5 x 10(-4) +/- 4.6 x 10(-5) m. A monotonic relationship was observed between flowrate and the ellipsoid's representative diameter. The effect of viscosity on flowrate was inconclusive, but the sensitivity of the ellipsoid's expansion to spatial variations in wall thickness was noted.

Summary: The effects of casein-to-whey ratios in fermented milk on gastric emptying, proteolysis and intestinal peptidome were investigated using an in vitro dynamic stomach-intestine system mimicking pre-school children digestion. The research found that the gastric emptying rate varied insignificantly among the milk samples. After 120 min digestion, the highest extent of proteolysis was observed at a casein-to-whey ratio of 2:1 due to the fewest gastric protein aggregates and relatively abundant caseins. Intestinal peptides derived from caseins or whey proteins showed a positive correlation with their parent protein content. The most abundant bioactive whey peptides were found at a casein-to-whey ratio of 1:1.5 after intestinal digestion. These findings demonstrated the importance of protein compositions in fermented milk on gastrointestinal proteolysis and peptide release in vitro, which is meaningful for future development of milk products that are more suitable for children.

Summary: This study quantified the diffusion and spatial distribution of gastric acids in whey protein isolate (WPI) gels during simulated digestion. It was found that regardless of NaCl concentration, the outer surface of the gels quickly formed a near-saturated layer with a higher acid concentration compared to the inner layer. The pH decrease was more significant in gels with higher NaCl concentration due to a looser network structure that facilitated acid diffusion.

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.
