Salt-induced colloidal aggregates can significantly influence contaminant fate and transport in natural and engineered systems. These aggregates' fractal dimensions (), ranging from 1.4 to 2.2, depend on various system variables. However, the quantitative relationship between these variables and of aggregates has not been fully explored, especially in predicting a wide range of . Here, we developed a random forest model capable of predicting the complete range of aggregate using just four simple physical and chemical parameters of the aggregating system as inputs. The model accurately predicts the of aggregates formed by colloids of different sizes, ranging from nano to micro sizes, after being trained and tested on appropriate data sets. Ionic strength (IS) has the most significant influence on the of aggregates formed by microsized particles followed by the relative hydrodynamic radius of aggregates (/), particle concentration (), and primary particle radius (). For aggregates formed by both nano- and microsized particles, IS still has a strong influence on the , with the significance of increasing. All four inputs are negatively correlated with predicting the of aggregates. The predictions align well with the physical interpretations.

In the present study, the effects of glucono-δ-lactone (GDL) as an acid reagent during thermal treatment on the quality of alkaline dough and steamed buns were examined. During the heating process, GDL improved the viscoelasticity and fluidity of the alkaline dough and enhanced intermolecular hydrogen bonding. The hardness of steamed buns was reduced by 61.

Determining the structure-function relationships of protein aggregates is a fundamental challenge in biology. These aggregates, whether formed in vitro, within cells, or in living organisms, present significant heterogeneity in their molecular features such as size, structure, and composition, making it difficult to determine how their structure influences their functions. Interpreting how these molecular features translate into functional roles is crucial for understanding cellular homeostasis and the pathogenesis of various debilitating diseases like Alzheimer's and Parkinson's.

Photodynamic therapy holds great potentials in cancer treatment, yet its effectiveness in hypoxic solid tumor is limited by the oxygen-dependence and insufficient oxidative potential of conventional type II reactive oxygen species (ROS). Herein, the study reports a supramolecular photosensitizer, BSA@TPE-BT-SCT NPs, through encapsulating aggregation-enhanced emission photosensitizer by bovine serum albumin (BSA) to significantly enhance ROS, particularly less oxygen-dependent type I ROS for photodynamic immunotherapy. The abundant type I ROS generated by BSA@TPE-BT-SCT NPs induce multiple forms of programmed cell death, including apoptosis, pyroptosis, and ferroptosis.

Extraintestinal (ExPEC), known to be the most common instigators of urinary tract infections (UTIs), represent such global threat. Novel strategies for more efficient treatments are therefore desperately needed.
