Multiple beam interferometry (MBI) evolved as a powerful tool for the simultaneous evaluation of thin film thicknesses and refractive indices in Surface Forces Apparatus (SFA) measurements. However, analysis has relied on simplifications providing fast or simplified recorded interference spectra. Here, we describe implementation new optics generalized fitting approach to 4 × transfer matrix method simulations SFA. Layers are described by dispersive complex indices, thicknesses, Euler angles...
Significance A surface forces apparatus was used with an electrochemical attachment to directly visualize reactions, dissolution, and pitting on surfaces when confined in nanoscale gaps (or “crevices”) real time. The results provide unique insights into how two closely apposed degrade under confinement, which is different from degradation of exposed bulk solution. Degradation proceeds via local nucleation “pits” at the periphery or center “contact area” that rapidly grow outward (in radius)...
The surface forces apparatus (SFA) was developed in the late 1960s as a powerful tool for investigating molecular interactions across apposing surfaces including first measurement of van der Waals and biologic liquid media. However, SFA has two major disadvantages. First, it traditionally uses white light interference between back-silvered muscovite mica to measure distances infer from distance shifts during interaction surfaces. Hence, force are not decoupled. Second, productive...
Controlling polymer–metal adhesion is critical in ensuring that materials can be cleanly separated during production processes without residue, which crucial for various industrial applications. Accurately characterizing on industrial-grade surfaces complex due to factors like surface roughness and actual contact area between the polymer. In this study, we quantified adhesive behavior of stainless-steel samples with varying treatments against a polymer using forces apparatus (SFA) reflection...
After almost 35 years of truly successful and transformative advancements, Atomic Force Microscopy (AFM) and, in general, scanning probe microscopy still have a fundamental limitation. This is constant drift uncontrolled motion tested surface structures with respect to each other. inherently linked the currently accepted design principle-only forces are measured, distances inferred from force measurements piezo motions. Here, we demonstrate test new setup, which combines advantages AFM...
