Abstract:
This study develops a Monte Carlo simulation framework for secondary electron emission, leveraging first-principles-derived energy loss functions to model inelastic scattering processes. The simulation incorporates distinct energy-loss mechanisms associated with different excitation regions in the momentum-energy plane. Furthermore, an experimentally parameterized surface excitation probability is integrated to differentiate between surface and bulk scattering events. By applying this model to TixNy compounds, the work clarifies how the differential inelastic scattering cross section governs the stoichiometry-dependent variation of secondary electron yields in TixNy systems.

Titration Calculations: Strong Acid - Strong Base
A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH. The pH at different volumes of added base solution can be calculated as follows:
(a) Titrant volume = 0 mL. The solution pH is due to the acid ionization of HCl. Because this is a strong acid, the ionization is complete and the hydronium ion molarity is 0.100 M. The pH of the solution is then:
