Effects of Hyporheic Exchange and Settlement on the Particle Size Distribution of Colloids
David Andrew Barry, Qihao Jiang
Colloid particle size plays an important role in contaminant adsorption and clogging in the hyporheic zone, but it remains unclear how the particle size changes during the transport of colloids. This study investigated the variation of the particle size of ...
New York2024Second harmonic scattering of nanoparticles: A journey into the electrical double layer
In aqueous solutions, a charged surface causes the redistribution of nearby ions. The ion layers formed are known as the electrical double layer (EDL), and are widespread in many systems involving electrochemistry, colloidal science, biomedicine, and energ ...
EPFL2024Spinel Protective Coatings for Solid Oxide Cell (SOC) Interconnects (ICs)
AbstractThe degradation of metal interconnects (ICs) in Solid Oxide Cells (SOCs) primarily results from chromium (Cr) oxide scale growth on stainless-steel substrates, causing ohmic loss and air-side electrode poisoning by Cr. This thesis addresses these c ...

2023Revealing the Formation Dynamics of Janus Polymer Particles: Insights from Experiments and Molecular Dynamics
Seeded emulsion polymerization is one of the best-known methods for preparing polymer particles with a controlled size, composition, and shape. It first requires the preparation of seed particles, which are then swollen with additional monomer (the same as ...
Washington2023Size dependence of second-harmonic scattering from nanoparticles: Disentangling surface and electrostatic contributions
Sylvie Roke, Arianna Marchioro, Bingxin Chu
Polarimetric angle-resolved second-harmonic scattering (AR-SHS) is an all-optical tool enabling the study of unlabeled interfaces of nano-sized particles in an aqueous solution. As the second harmonic signal is modulated by interference between nonlinear c ...
AIP Publishing2023Hydrogel-Encased Photonic Microspheres with Enhanced Color Saturation and High Suspension Stability
Regular arrays of colloidal particles can produce striking structural colors without the need for any chemical pigments. Regular arrays of colloidal particles can be processed into microparticles via emulsion templates for use as structural colorants. Phot ...
Washington2023Optical manipulation of plasmonic nanoparticles: Applications in surface chemistry and nano-optics
Optical tweezers are devices that can manipulate nano- and microparticles using a laser. The principle of optical tweezers is to apply a force to an object using the momentum of light. This force is very small, but it is sufficient to move things in the mi ...
