Development of a Flotation Rate Equation from First Principles under Turbulent Flow Conditions
… 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 frequencies, attachment and detachment energies, and how the …

Simulation of axisymmetric stepped surfaces with a facet
… presence of these steps, which act as sites for attachment and detachment of diffusing adsorbed atoms ('adatoms'). In the absence of material deposition and evaporation, steps move in response to two main physical effects: line tension, which is caused by curvature of the step edge, and step-step …

Tddft Derivative Couplings And Other Topics In Quantum Chemistry
… which is used to calculate the electron attachment/detachment energy, and the Bethe-Salpeter equation, which is used to obtain the electron excitation energies of a system.

Development and Validation of a Simulator based on a First-Principle Flotation Model
… bubble generation, bubble-particle collision, attachment, detachment, and froth phase recovery. The process of bubble-particle attachment has been modelled on the premise that bubble-particle attachment occurs when the disjoining pressure of the thin liquid in a wetting films formed between …

Mathematical modelling of agglomerate scale phenomena in heap bioleaching
… a s.ze distribution of ore particles, microbial attachment, detachment and oxidation processes, and the transport of chemical and microbial species to and from the agglomerate. Isothermal agglomerate conditions, and a uniform distribution of reagents in the stagnant liquid phase, are among the …

The effect of energy input on flotation kinetics
… simulated flotation rate constants and attachment-detachment flotation rate constants. Here, simulated flotation rate constants were calculated using a literature fundamental model for flotation in turbulent systems. This model is based on suitable expressions for the collision …

Design and evaluation of neuroregenerative properties of 4D hydrogel scaffolds
… between cells and engineered materials (i.e. attachment-detachment, or that influence cell development, function or fate) are central challenges towards progress in the development of biomedical devices and regenerative medicine therapies. A particularly complex system to translate in vitro is …

Shape and Stability of Epitaxial Nanostructures Evolving under Growth or Annealing
… disappear. A linear decay rate suggests an attachment/detachment dominant mechanism. We also report on the shape transition and migration of TiSi2 nanostructures embedded in a Si matrix. Grown multifaceted TiSi2 were exposed to a Si flux under different growth conditions forming a thick …

Pragmatics of attachment and detachment: medium (un)specificity as material agency in contemporary art
… The processual inter-relational model of ‘attachment/detachment’ is offered as a conceptual framework and overarching practice methodology that maintains these productive tensions and opens up a complexity through which the medium specific can be mapped in a fluid and fragmentary way. Three …

Embedded-fragment studies of ice, water, and molecular cluster cations
… were found to be nearly equal. The transient attachment, detachment, and exchange of this weakly bound fifth molecule seems to to play a large role in fluctuations of the hydrogen bonding network. Because the viability of BIM and related fragment methods depends on weakly interacting monomers …

Selective Isolation of Circulating Tumor Cells in Antibody-Functionalized Microsystems
Attachment of circulating tumor cells in microfluidic devices functionalized with proper antibodies was studied. Under static experimental conditions, microchambers were utilized to study the parameters such as cell suspension concentration, incubation time or ambient temperature that may affect …

Διερεύνηση της μηχανικής συμπεριφοράς οστεοβλαστών κατά την προσκόλλησή τους σε υποστρώματα φυσικών βιοϋλικών
Η κατανόηση των φαινομένων που λαμβάνουν χώρα κατά την αλληλεπίδραση κυττάρου βιοϋλικού και η συσχέτιση μηχανικών παραμέτρων του κυττάρου με πολύπλοκες διεργασίες στο εξωκυττάριο (ECM) περιβάλλον οδηγεί το μέλλον στο σχεδιασμό των βιοϋλικών. Σκοπός της διατριβής ήταν η διερεύνηση της προσκόλλησης …
