Summary: This study analyzed the influence of various factors such as particle size, particle shape, shear rate, and time on the rheological properties of cement-based slurry. The results showed that particle size has a greater impact on the rheological properties compared to particle shape. Additionally, small particle size samples are significantly affected by shear rate, and the rheological parameters increase over time. The study also identified rheological models suitable for different materials and provided recommendations for selecting an appropriate rheological model to evaluate rheological parameters.

Summary: The recent increase in plastic use and pollution has created a strong demand for bioplastics. This study investigates the use of biochar (BC) as a filler in poly(lactic acid) (PLA)/starch composites. The results show that the particle size and loading of BC greatly influence the mechanical properties of the composites. A combination of smaller particle size and lower loading leads to increased tensile strength and toughness of the composites.

Summary: This study investigated the effects of interactions between biochar particles of varying sizes and common clay minerals on the surface properties of biochar and its capacity for Cd sorption. The results showed that the Cd sorption capacity of large biochar particles increased after interaction with clay minerals, while the Cd removal capacity of small biochar particles decreased. Analysis revealed that COO- groups on the initial biochar had the highest sensitivity for Cd adsorption.

Summary: The study systematically investigated the mechanical properties of Magnetorheological plastomers (MRPs) with different types of secondary particles through experiments and simulations. It was found that the addition of glass balls led to an increase in mechanical properties, while SiO2 and Fe3O4 particles exhibited conflicting behaviors. Simulation of microstructures in MRPs revealed the effect of secondary particles on the microstructure and mechanical properties of MRPs.

Summary: This study explores the possibility of using biochar as a soil amendment for modifying thermal backfill characteristics, investigating the effects of different biochar content amounts and particle size fractions on two types of soils. The results show that biochar amendment reduces both thermal and mechanical properties of the soil, with variations depending on biochar fraction and soil type. Further research is needed to fully understand the impact of biochar on soil properties.

Summary: Fillers in rubber composites, such as carbon black and biochar, have diverse physicochemical properties influenced by feedstock sources and pyrolysis conditions. This review aims to compare the properties of biochar and carbon black to assess biochar's suitability as a replacement filler. The mechanical performance of biochar will be evaluated against the reinforcing ability of carbon black.

Summary: In this study, stable gel-like emulsions were prepared using gamma-zein particles, and the effects of homogenization pressure on the structure and rheological properties of the emulsions were investigated. The results showed that increasing the homogenization pressure resulted in stronger gel-like structures and changed the rheological properties of the emulsions. Additionally, emulsions prepared with microfluidization exhibited different rheological behaviors.

Summary: This study predicts the rheological properties of concrete with irregular aggregate using a multi-level biphase assumption. The proposed models demonstrate power-law relationships between relative viscosity, relative yield stress, and relative thickness of suspending media. The accuracy and robustness of the models are proven for mixtures with various particle shapes and size distributions of manufactured sand and coarse aggregate. The predicted influences of particle shapes on the rheological properties can be represented by their effects on relative paste film thickness and relative mortar film thickness. The proposed multi-level prediction lays the foundation for mix proportioning of concrete with irregular aggregate based on specified rheological requirements.

Summary: The study found that bone and shrimp-based biochars showed the highest catalytic activity for TCE reduction, while graphite and activated carbon showed no reactivity. Multivariate regression analysis indicated that the catalytic activity of biochar is controlled by multiple properties, including surface area, TCE sorption, abundance of C-O groups, and pore size.

Summary: This study aimed to clarify the factors influencing the rheological properties of barley batter and dough, focusing on particle properties and their effects on the beta-glucan elution. The results showed that particle size had an impact on the rheological properties of batter, with smaller particles leading to increased beta-glucan concentration, yield stress, and dynamic viscoelasticity. A dispersed particle state model was proposed based on these findings.
