Molecular adsorbate effects on graphite–silica superlubricity: A ReaxFF investigation by Marcus C. Perovich, Luis E. Paniagua-Guerra, Qian Mao, Seong H. Kim, Adri C. T. van Duin, Bladimir Ramos-Alvarado

“…Additionally, adsorption, and binding energy calculations were performed to expand upon the hypothesis that friction may be directly correlated to the interfacial molecular structure rather than binding energy and adsorbate commensuration with graphene. By quantitatively representing the interfacial roughness of each adsorbate, the hypothesis was confirmed by unequivocally explaining the calculated friction coefficients.…”

Direct contact condensation of two-phase ammonia in the co-current subcooled liquid flow at the low mass fluxes by Vasyl Ruzaikin, Ivan Lukashov, Andrii Breus, Olena Torosian

“…The observed condensation front enabled the determination of average plume length under different boundary conditions and the estimation of conservative condensation heat transfer coefficients. The results indicate that existing models and correlations—primarily developed from steam-water experiments—fail to adequately predict ammonia condensation behaviour, both qualitatively and quantitatively. …”
