Study of the Influence of the Crystallographic Orientation of Cassiterite Observed with Colloidal Probe Atomic Force Microscopy and its Implications for Hydrophobization by an Anionic Flotation Collector

“…The colloidal probes were prepared using U.V. glue (Ber-Fix Gel), and the silanization of the spherical silica was followed by the steps described by Babel and Rudolph . Tipless All-in-One B and TL-CONT (Nano and more GmbH) cantilevers were used for the hydrophobic silanized silica particles and silica particles, respectively.…”

Influence of engineered roughness microstructures on adhesion and turbulent resuspension of microparticles

“…A Park Systems NX12 atomic force microscope is utilized for colloidal probe preparation, cantilever characterization, which includes calibration, and force-distance measurements. As illustrated in Figure 3, the colloidal probe cantilevers are prepared by gluing a representative 100 µm spherical particle, which involve Ber-Fix UV-Kleber with an All-In-One Aluminum-coated B type cantilever from Budget Sensors (Babel & Rudolph, 2019). Prior to attaching the particle, the force constant of the cantilever is determined using the procedure described in the authors' previous work (Rudolph & Peuker, 2014), which contains all the relevant details about the force constant calibration.…”

Surface Forces in Chemical Mechanical Planarization and Semiconductor Wafer Cleaning Systems

“…With a known cantilever constant k (spring constant) and deflection (displacement) the interaction force is calculated according to Hooke's law. The AFM colloidal probe technique is a reliable method for interaction force measurement in aqueous medium [6][7]. Force measurement can be done with the cantilever tip or with a particle glued to a tipless cantilever such as the 20µm aluminum oxide particle (Figure 2A) or the 0.7 µm silica particle (Figure 2B) [8].…”

“…Hydrophobic interactions belong to the strongest forces observed at the nanoscale, yet they seem to be the least understood interactions, currently described only by empirical equations. They are characterized by a strong attraction between hydrophobic surfaces in water, often accompanied by formation of bridging cavities [6] and nanobubbles, [7], [22] see Figure 5. [23] Surfaces composed from different materials interact with the force depending upon the surface charge, surfactant adsorption density and form, and the adhesion/cohesion effect.…”
