Alginate microspheres stand out in the field of drug delivery due to their biocompatibility and high conversion rate. However, there are certain drawbacks in their preparation technology and further research is needed on how to prepare alginate microspheres with uniform particle size using high-viscosity sodium alginate solution. Therefore, this study proposed a novel microfluidic membrane emulsification technique for the preparation of alginate microspheres from high-viscosity sodium alginate solution. A tumor microenvironment-responsive colorectal cancer-targeted oral drug delivery system was constructed using a disulfide-bonded coupling of honokiol and doxorubicin as a model drug to achieve precise targeting, efficiency enhancement and toxicity reduction. The results showed that the prepared microspheres were relatively homogeneous in particle size. The <em>in vitro</em> model showed the high stability of the microspheres in the gastric acid environment and the colon-targeted release characteristic. And the system triggered the breakage of redox bonds and the precise release of the drug, showing good antitumor activity.

Computational studies of irregularly shaped particles are challenging but necessary to gain a better understanding of the flow of particulate matter. This study focuses on the behaviour of irregular sinter particles and applies the discrete element method to examine the effects of static and rolling friction coefficients and particle shape on the angle of repose and porosity of sinter piles. A three-dimensional model of an irregular sinter particle reconstructed by close-range photogrammetry served as the template for generating multi-sphere particles with varying numbers of sub-spheres (1, 3, 7, 22, and 135) and sphericity ranging from 1 to 0.69. Simulations of particle piles were conducted for a range of values of the coefficients of static and rolling friction. The results indicate that the angle of repose increases with static friction and also increases with rolling friction coefficient when it is lower than the static coefficient. The angle of repose shows clear dependence on particle shape, particularly for lower rolling friction coefficients. The friction coefficients for particles of five different shapes were individually determined through bulk calibration, and irregularly shaped particles in DEM were found to require lower friction coefficients. Porosity was marginally affected by the static and rolling friction coefficients for spherical particles, while non-spherical particles showed porosity increasing with the rolling friction coefficient. The relationship between particle sphericity and porosity was nonlinear: as sphericity decreases from 1.00 to 0.69, the porosity first decreases to a minimum and then increases. The findings confirmed that both friction and particle shape have a significant influence on the structure of sinter piles, with implications for material handling and processing in industrial applications.</div></div>","PeriodicalId":401,"journal":{"name":"Particuology","volume":"98 ","pages":"Pages 231-240"},"PeriodicalIF":4.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143508557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The particle position and velocity are then numerically accessed using in-house developed XDEM code (Extended DEM). The new position and velocity of the particles are transferred back to IBM, and this keeps repeating till the final time step. A module is added to the calculate the effect of magnetic force on the particles in XDEM which is then validated with a benchmark case.
