Surface Chemistry & Adsorption

The study of chemical phenomena at interfaces — from Langmuir monolayer adsorption and BET multilayer analysis to wettability, surface tension, and heterogeneous catalysis on solid surfaces.

Surface chemistry investigates the unique chemical and physical processes that occur at the boundary between two phases. Atoms and molecules at surfaces have unsatisfied bonding, making them extraordinarily reactive compared to bulk material. This reactivity drives everything from industrial catalysis and corrosion to self-cleaning coatings and semiconductor fabrication.

These simulations let you explore Langmuir and BET adsorption isotherms, measure contact angles and wettability, visualize surface tension and capillary rise, and discover the Sabatier principle that governs heterogeneous catalysis — all with real-time parameter control and animated visualizations.
