Localization Model description of interfacial dynamics of free-standing nanoparticles and thin films, and nanoparticle on supporting interacting substrate
DownloadFall 2022
Localization model (LM) relates, without any free parameter, slow dynamics of α-relaxation time (τα) to fast dynamics of Debye-Waller Factor (DWF) or ⟨u2⟩, which is the mean square displacement of particles at a caging time on the order of picoseconds. Moreover, localization model can also...

Stimuli-Responsive and Self-Healing Nanocomposite Hydrogels Based on Reversible and Dynamic Crosslinks
DownloadFall 2022
Hydrogels, due to their soft and water abundant natures, highly resemble human skins and tissues and thereby have attracted extensive attention in recent years. Functional hydrogels showing responsiveness to various stimuli such as pH, temperature, strain and pressure are promising for a wide...

Dynamic Interfacial Tensions and Dilatational Viscoelastic Properties of Asphaltenes at Oil/Water Interface at High Pressure and High Temperature Conditions
DownloadFall 2021
The dynamic interfacial tension and dilatational viscoelasticity behaviors of asphaltenes at oil/water interfaces were investigated by means of an oscillating droplet tensiometer. This oscillating droplet tensiometer was modified to handle temperature of 120 °C and pressure up to 700 kPa. For...

Functional materials for destabilizing and stabilizing emulsions and underlying interfacial interaction mechanisms
DownloadFall 2021
Oil related issues such as oil/water emulsions are critical challenging issues in a wide range of engineering processes and have caused negative effects to economy, environment, and ecology. Despite much effort devoted to this area, the developed materials remain many limitations. For example,...

Prebiotic-Chemistry Inspired Polymeric Coatings for the Surface Modification of Hydrophobic Polyethersulfone membranes for the Enhancement of their Antifouling and Antibacterial Properties
DownloadFall 2020
Polyethersulfone (PES) membranes are very commonly used for wastewater treatment because of their excellent mechanical, chemical and thermal properties. However, the major concern associated with these membranes is their susceptibility to fouling due to their intrinsic hydrophobicity. Therefore,...

Probing the Interaction Mechanisms among Asphaltenes, Fine Solids, Water-Oil Emulsions and Pipeline Surfaces in Oil Sands Production
DownloadSpring 2020
Fouling problem has been one of the most challenging problems in oil industries. Asphaltenes, fine solids, and water-oil emulsions have been regarded as the major components in the fouling phenomena during oil production. Investigating the interactions between foulants (e.g., asphaltenes, fine...

Functional Supramolecular Materials Based on Multiple Hydrogen-Bonding Motifs and the Associated Molecular Interaction Mechanism
DownloadFall 2019
Engineered multifunctional polymers with stimuli-responsive and self-healing properties have drawn increasing attention in recent years for the development of “smart” materials with a broad range of applications. Hydrogen bonding, as one of the most developed approaches in supramolecular...
