Application of Extended DLVO Theory: Modeling of Flotation and Hydrophobicity of Dodecane
The extended DLVO theory was used to develop a flotation model by considering both hydrodynamic and surface forces involved in the process. A stream function was used to estimate the kinetic energies for thinning the water films between bubbles and particles, which were compared with the energy …

Anti-Adhesive Si-and F-Doped DLC Coatings and Micro-Nanostructured Surfaces for Medical Implants
… 65%, compared with uncoated stainless steel. The extended DLVO theory was used to explain the bacterial adhesion mechanism. Quartz Crystal Microbalance technology (QCM-D), which is a simple, efficient, reliable, real time and information-rich method for measuring bacterial adhesion and related …

Development of a Flotation Rate Equation from First Principles under Turbulent Flow Conditions
… electrostatic, and hydrophobic) by use of the Extended DLVO theory. The model includes probabilities for attachment, detachment, and froth recovery as well as a collision frequency. A review of the effects fluids have on the flotation process has also been given. This includes collision …

Hydrophobic Forces in Free Thin Films of Water in the Presence and Absence of Surfactants
… at shorter separation distances. These non-DLVO forces may be attributed to the steric repulsion between asphaltenes extracted on the bitumen surface. The steric forces increased with pH and temperature, which may be explained by the increased solubilization of asphaltenes in water. The …

Quantitative analysis of protein liquid-liquid phase separation
… using Derjaguin- Landau-Verwey-Overbeek (DLVO) theory. It was achieved by constructing a Monte-Carlo model that can produce simulated scattering curves from interaction potential parameters, with a surrogate machine learning model that may produce comparable results within shorter time …

A fundamental study of the selective hydrophobic coagulation process
… higher than those predicted by the classical DLVO theory, suggesting that it is driven by a hydrophobic interaction energy. Thus, the process is referred to as the selective hydrophobic coagulation (SHe) process. The fundamental development of this process is the focus of this study. In this …

Development and Evaluation of NI-P-PTFE Based Nano-Composite Coatings for Medical Devices
… adhesion and removal were also investigated. Extended DLVO theory also explained why some coatings adhered less bacteria than others by analysing total interaction energy between bacteria and the coatings. While in the corrosion test, open circuit potential, polarization resistance (Rp), …

Solution and Adsorption Characterization of Novel Water-Soluble Ionic Block Copolymers for Stabilization of Magnetite Nanoparticles
… the modified Deryaguin-Verwey-Landau-Overbeek theory. Novel hydrophilic triblock copolymers comprised of poly(ethylene oxide) tailblocks and a carboxylic acid containing polyurethane center block were examined by static and dynamic light scattering (SLS and DLS), small angle neutron scattering …

Surface and Hydrodynamic Forces in Wetting Films
… work on the basis of the Reynolds lubrication theory. The technique has been used to study the effects of surface hydrophobicity, electrolyte (Al3+ ions) concentration, and bubble size on the stability of wetting films. Further, the geometric mean combining rule has been tested to see if the …

Development of a turbulent flotation model from first principles
… kinetics of bubble-particle attachment using the DLVO extended to include contributions from hydrophobic force and the theory of turbulent collision. The froth-phase model is based on predicting the rate of bubble-particle detachment by considering bubble coarsening and water recovery. The …
