in this research, the effect of bubble surface area flux, sb, and particle size on flotation rate constant, k, of pyrite (fes2) particles was studied using bubble-particle interactions. the bubble-particle collision, attachment and detachment efficiencies were calculated under different flow regimes. the k increased with increase in the collision efficiency and decrease in the detachment effici...

Using electrospray ion beam deposition, we collide the complex molecule Reichardt's Dye (C41H30NO+) at low, hyperthermal translational energy (2-50 eV) with a Cu(100) surface and image outcome single-molecule level by scanning tunneling microscopy. We observe bond-selective reaction induced kinetic energy. The collision impulse compresses bends specific bonds, prompting them to react selectivel...

Cross sections and thermal rate coefficients are computed for electron-impact dissociative recombination vibrational excitation/de-excitation of the N$^+_2$ molecular ion in its lowest six levels, collision energies/temperatures up to 2.3 eV/5000 K.
