The findings additionally show that advanced machine learning methods can significantly improve HSP prediction accuracy, facilitating more precise solubility estimates and advancing applications in chemical and materials science.
These findings underscore the potential of machine learning to improve HSP prediction, with significant implications for solvent design, chemical engineering, and materials science.

There may be two reasons. (1) Arrangement is random due to the accumulation of granular particles of bulky rock material and contact between the particles cannot be determined. (2) Bulk materials is a kind of non-tacky geotechnical materials with larger particle size.

Samples of Al2O3-C materials were prepared, based on the tabular corundum and recycled materials as raw materials, natural graphite as carbon source, Si as antioxidant and phenolic resin as binder.
In China, the waste of refractory materials are usually burried, while the recycled materials only accounted for 30%[3].
Experiment 1.1 Raw materials for experiment Tabular corundum and recycled material which is 0.5~0.1mm in particle size are used as the raw materials for experiment.
Therefore the strength of samples decrease. 2.2 Effect of the amount of recycled materials on microstructure of the Al2O3-C materials Photos of samples added recycled materials and not by SEM are shown as Fig.2.

Those elastic materials cause non-linear stiffness and friction in dynamics.
Therefore, just materials properties of hydraulic oil and seals are mathematically modeled.
In many domestic applications, hydraulic fluids are treated as incompressible materials.
It shows that properties of fluid materials effect obviously on system dynamics.
