Properties of Solutions | Boundless Chemistry

In order to form a solution, the solute must be surrounded, or solvated, by the solvent. Solutes successfully dissolve into solvents when solute-solvent bonds are stronger than either solute-solute bonds or solvent-solvent bonds. Qualitatively, one can determine the solubility of a solute in a solvent by using the rule "like dissolves like".

Sonofragmentation – The Effect of Power Ultrasound …

Sonofragmentation describes the breakage of particles into nano-sized fragments by high power ultrasound. In contrast to the common ultrasonic deagglomeration and milling – where particles are mainly grinded and separated by inter-particle collision –, sono-fragementation is distinguished by the direct interaction between particle and shock wave.

Experimental Evaluation of the Shear Behavior of Fiber …

In the RS tests, the breakage intensity of calcareous sands increased with the vertical loading stress, fiber content, and fiber length. At low fiber content and length, the interparticle contacts and interlocking effects influenced the shear strength and particle breakage significantly, while at higher fiber content, the role of fiber friction and tension forces became dominant.
