Nanofabrication has been utilized to manufacture one-, two-, and three-dimensional
functional nanostructures for applications such as electronics, sensors, and photonic …

Self-assembly of quasi-spherical colloidal particles in two-dimensional (2D) arrangements is
essential for a wide range of applications from optoelectronics to surface engineering, from …

Abstract Characterization of the morphology, identification of patterns and quantification of
order encountered in colloidal assemblies is essential for several reasons. First of all, it is …

Synthetic active colloids that harvest energy stored in the environment and swim
autonomously are a popular model system for active matter. This emerging field of research …

Measurements of droplet phase and interfacial tension (IFT) are important in the fields of
atmospheric aerosols and emulsion science. Bulk macroscale property measurements with …

We demonstrate that application of an oscillatory electric field to a liquid yields a long-range
steady field, provided the ions present have unequal mobilities. The main physics is …

Electrocoagulation (EC) is an efficient technology for removing oil-in-water (O/W) emulsions.
However, the role of the electric field in EC for demulsification remains unclear and an …

Many industrial processes generate “oily wastewaters”, characterized by low volume
fractions of micrometer-scale, oil-in-water droplets that are difficult to separate by …

Nonclose-packed colloidal arrays have many potential applications ranging from plasmonic
sensors, light trapping for photovoltaics, to transparent electrodes. However, scalable …

Colloidal particles adjacent to electrodes have been observed to exhibit drastically different
aggregation behavior depending on the identity of the suspending electrolyte. For example …
