Nucleation and Growth of Calcium Carbonate and Sulfate Minerals from Solutions Close to Equilibrium
… macroscopic growth rates were measured using a quartz crystal microbalance with dissipation (QCM-D) under close to equilibrium conditions. The results showed well agreement with those reported microscopic growth rates measured by atomic force microscopy (AFM) and other macroscopic measurement …

Bacterial transport and horizontal gene transfer in subsurface: multiple-scale experimental studies
… may influence bacterial transformation with adsorbed DNA on surfaces. The objectives of this thesis were to investigate the physicochemical and biological factors affecting the extracellular DNA-bacterial cell interaction and the natural transformation, with a long-term goal of modelling …

Organic Self-Assembled Films for Nonlinear Optics: Film Structure, Composition and Kinetics of Film Formation
… and characterization of organic materials with NLO properties using a self-assembly approach by alternately dipping a charged substrate into positively and negatively charged polymers to build up layer-by-layer (LbL) films. The effect of solution pH on the formation of LbL films fabricated …

Electric Field Effects on Bacterial Deposition and Contaminant Sorption as Drivers of Bioavailability
… denotes the ‘degree of interaction of chemicals with living organisms’. High bioavailability is generally needed for efficient biodegradation of environmental contaminants. Therefore, technologies to promote contaminant availability should foster bacterial transport and/or control interactions of …

Studies of Sustainable Polymers: Novel Lignins to Reprocessable Polymers
… and degradation were monitored by a quartz crystal microbalance with dissipation (QCM-D). Atomic force microscopy (AFM) was applied to investigate the topologies of the copolymer and degraded films. Horseradish peroxidase (HRP) was used as the enzyme for the dehydrogenative …

Mechanisms of Adsorption and Surface-Mediated Aggregation of Intrinsically Disordered Protein Tau at Model Surfaces
… mutations of tau protein at model surfaces. A Quartz Crystal Microbalance with Dissipation (QCM-D) was used to monitor the adsorption of different tau species at nanomolar concentrations, mimicking the in vivo situation, to surfaces with different surface charge, wettability and softness, while …

Surface Plasmon Resonance Imaging Biosensors for Cancer Diagnosis: Detection of Circulating Tumor DNA
… (PLL) polypeptide backbone modified with an anionic peptide, connected via a nonionic OEG spacer, has been synthesized in order to achieve control over the charge distribution of PLL-coated surfaces, and thus the antifouling property. The PLL backbone has been functionalized with …

Host-Guest Assemblies for Functional Interfaces via Langmuir-Blodgett and Self-Assembly Technique
… In our work, 3-dimensional host structures with cavities are constructed on a targeted solid substrate using Langmuir-Blodgett and self-assembly techniques. In particular, by adopting the fundamental concept of host-guest interaction in supramolecular chemistry, we expect that structurally …

Investigation of Asphaltene Adsorption at Liquid-Liquid and Liquid-Solid Interfaces
… asphaltenes form a class of crude oil components with a wide distribution in molecular structures and this brings about polydispersity in surface activity, adsorption behaviors, and aggregate formation. The effects of polydispersity in mixtures of asphaltene molecules affect their dilatational …

Mechanism study of virus removal in membrane filtration and the application to improve virus removal
… practice and a wider acceptance can be expected with a reliable control of the water quality. Pathogenic viruses in municipal wastewater can result in outbreaks of virus infection without sufficient removal. Membrane bioreactor (MBR) has shown its promise to remove virus in municipal wastewater …

Aib(2)oxyntomodulin Peptide Molecular Self-Assembly: Smart Nanostructures Toward Long Acting Formulation for Obesity and Diabetes Type 2
… comparable to those of natural assemblies found within cells, such as actin and tubulin (0.3 - 1.2 GPa), which were previously found to be the reversible self-assembled fibrils, *in vivo*. This finding supports the possibility of the controlled dissociation mechanism of Oxm and Aib2-Oxm fibrils, …
