Analysis of the general uncertainty propagation and calculation of the systematic uncertainty of the Neumann Equation of State for surface free energy determination
Jonathan M. Schuster, Carlos E. Schvezov, Mario R. Rosenberger
The determination of the surface free energy of solid materials provides information to explain and understand a wide variety of phenomena in surface science. One o…
Polynomial functions for direct calculation of the surface free energy developed from the Neumann Equation of State method
Jonathan M. Schuster, Carlos E. Schvezov, Mario R. Rosenberger
The Neumann Equation of State (EQS) allows obtaining the value of the surface free energy of a solid from the contact angle of a probe liquid with known surface tens…
Construction and calibration of a goniometer to measure contact angles and calculate the surface free energy in solids with uncertainty analysis
Jonathan M. Schuster, Carlos E. Schvezov, Mario R. Rosenberger
Here, we present the construction and calibration of a low-cost goniometer to measure contact angles by the sessile drop method. Besides, we propose a simple and fast method to cal…
