Understanding biofilm rheology is crucial for industrial and domestic food safety practices. This comprehensive review addresses the knowledge gap on the rheology of biofilm. Specifically, the review explores the influence of fluid flow, shear stress, and substrate properties on the initiation, structure, and functionality of biofilms, as essential implications for food safety.

Although the fatigue properties of asphalt materials have been extensively studied, the relationship between the rheological properties and road performance of asphalt mixtures remains underexplored. In this study, we have examined the relaxation properties of asphalt binders through relaxation tests conducted on asphalt and its mastic under different conditions. A repeated stress relaxation-recovery test is designed for assessing both the relaxation and elastic properties, and a set of reasonable test parameters is recommended, thereby establishing a novel test method for measuring the relaxation and elastic behaviors of asphalt.

Acrylic pressure-sensitive adhesives (PSAs) are widely applied in transdermal drug delivery systems (TDDS). However, the molecular mechanisms underlying the effect of functional groups of PSAs on drug release and transdermal permeation properties remain insufficiently clear. In this study, we investigated the effect of acrylic PSAs' functional groups on the in vitro release and transdermal permeation properties of a model drug guanfacine (GFC).

Hydrogels mimic natural environments due to their hydrated, polymeric networks which are beneficial for microorganism growth. The substantial water content maintains a consistently moist environment, and porous structure of hydrogel promotes efficient nutrient transfer and cell distribution, offering advantages over traditional liquid bioreactors. While their application in cell immobilization for bioconversion is well-known, their use as a solid-state fermentation matrix remains unexplored.

In this study, the improvement effects of different polymeric saccharides, including native starch, maltodextrin and inulin, replacing 10 % sucrose on the physical characteristics and creaminess perception of non-fat whipped cream system were investigated. Systems containing maltodextrin had more uniform particle size and bubble distribution. This resulted in higher whipping performance and lower friction characteristics.
