Wall accumulation of confined active Janus colloids due to effective active diffusivity
Sandeep Ramteke, Alicia Boymelgreen, Jarrod Schiffbauer
Electrokinetically-driven Janus colloids, e.g., with one metallic and one dielectric hemisphere, confined between parallel walls exhibit a boundary-accumulation mechanism enabled b…
Expanding Active Matter to the Third Dimension: Exploring Short and Long-Range Particle-Wall Interactions
Sandeep Ramteke, Jordan Dehmel, Touvia Miloh +2
Most active colloid experiments are quasi-2D. Here a 3D density-matched solution of active particles propelled and aligned with an AC electric field uniquely facilitates measuremen…
YOLOv5 vs. YOLOv8 in Marine Fisheries: Balancing Class Detection and Instance Count
Mahmudul Islam Masum, Arif Sarwat, Hugo Riggs +2
This paper presents a comparative study of object detection using YOLOv5 and YOLOv8 for three distinct classes: artemia, cyst, and excrement. In this comparative study, we analyze…
The influence of frequency and gravity on the orientation of active metallo-dielecric Janus particles translating under a uniform applied alternating-current electric field
Alicia Boymelgreen, Golak Kunti, Pablo Garcia Sanchez +1
Theoretical and numerical models of active Janus particles commonly assume that the metallo-dielectric interface is parallel to the driving applied electric field. However, our exp…
Analysis of Cargo Loading Modes and Capacity of an Electrically-Powered Active Carrier
Xiaoye Huo, Yue Wu, Alicia Boymelgreen +1
The use of active colloids for cargo transport offers unique potential for applications ranging from targeted drug delivery to lab-on-a-chip systems. Previously, Janus particles (J…
Mobile Microelectrodes: Towards active spatio-temporal control of the electric field and selective cargo assembly
Alicia M Boymelgreen, Tov Balli, Touvia Miloh +1
With an eye towards next-generation, smart, micro/nanofluidic devices, capable of responding to external stimuli or changes in environment, we demonstrate a means to achieve dynami…
