This study aims to address the question of fluctuation-dissipation relationship in a non-equilibrium system comprising active Brownian particles. Specifically, the fluctuation power spectral densities (PSD) of an Induced-ChargeElectrophoresis-driven

Although patients with acute respiratory distress syndrome require mechanical ventilation, these ventilators often exacerbate the existing lung injury. For example, the cyclic closure and reopening of fluid-filled airways during ventilation can cause

Inclusion complexation kinetics of methyl-β-cyclodextrin (m-β-CD) to hydrophobic molecules confined in an isolated droplet was investigated with optical tweezers. The radius of the droplet shrank over time as m-β-CD was introduced into the sample

The characterization of hydrophobically modified alkali-soluble emulsions (HASE) using conventional techniques such as gel permeation chromatography or static light scattering is difficult because of the hydrophobic association. Two different approac

We report a study of the dynamical behaviour of a polystyrene latex sphere in a telechelic poly(ethylene oxide) solution using optical tweezers. With this new technique, we use a position-sensing detector and a lock-in amplifier to measure the displa

Significant adsorption of polystyrene-poly(ethylene oxide) (PS-PEO) diblock copolymers onto PS latex particles in an aqueous dispersion is accomplished through suppression of micelle formation by adding tetrahydrofuran (THF) as a cosolvent. We add TH

Static light scattering measurements of ethylene-propylene random copolymer revealed that solvophobic ethylene segments were responsible for both aggregation and cluster density variations over temperature. By changing the molar ratio of ethylene to

Intrinsic viscosity measurements of 80-20 molar ratio ethylene-propylene (EP) copolymers in selective solvents have shown a dramatic decrase in viscosity when temperature was lowered from 50 to -10°C. In this study it is shown that both chain associ

We report a novel method, the optical bottle that was used to directly measure the osmotic bulk modulus for a colloid suspension. We determined the bulk modulus by optically trapping multiple nanoparticles and considered a mechanical balance between
