Surface characterization of the cement for retention of implant supported dental prostheses: In vitro evaluation of cement roughness and surface free energy

Reduction of bacterial adhesion on titanium-doped diamond-like carbon coatings

“…The influence of total surface energy on bacterial adhesion has been investigated intensively, with the frequent conclusion that bacterial adhesion is less on low energy surfaces and easier to clean because of weaker binding at the surface interface (Ahn et al 2009;Liu and Zhao 2011;Brajkovic et al 2014). Brajkovic et al (2014) demonstrated that the surfaces with lower values of surface energy were less prone to biofilm adhesion and the number of adhered bacteria increased with increasing surface energy. However, there are also a number of contrary findings that suggest high energy surfaces have a smaller biofouling tendency and higher removal rate than low energy surfaces (Brink et al 1993;Pasmore et al 2001).…”

Influence of TiO2 content on the mechanical and tribological properties of Cr2O3-based coating

“…If the surface free energy of the coating is high, the bonding phenomenon between the friction pair and the coating will take place easier in the sliding process and form the resistance force. Thus the friction coefficient under the same load conditions will increase [27][28][29]. Conversely, it will form a small cohesive force when the coating is at a lower surface free energy state, which leads to a relatively easy movement between the coating and the friction pair.…”

Rebound and attachment involving single bubble and particle in the separation of plastics by froth flotation

“…The surface free energies (c) were calculated by the three liquids phase method based on Van Oss-Chaundhury-Good theory of wettability [31,32], which are shown in details in Appendix A.…”

“…According to the Van Oss-Chaundhury-Good theory of wettability [31,32], total surface free energy can be expressed as:…”
