Kailasham R, Khair A
Soft Matter . 2024 Nov; 20(46):9193-9207. PMID: 39531013
Active Brownian disks moving in two dimensions that exchange information about their internal state stochastically are chosen to model epidemic spread in a self-propelled population of agents under the susceptible-infected-recovered-susceptible...

Liu Y, Kailasham R, Moerman P, Khair A, Zarzar L
Angew Chem Int Ed Engl . 2024 Sep; 63(49):e202409382. PMID: 39321140
Non-equilibrium patterns are widespread in nature and often arise from the self-organization of constituents through nonreciprocal chemotactic interactions. In this study, we demonstrate how active oil-in-water droplet mixtures with predator-prey...

Yang A, McKenzie B, Pavlat B, Johnson E, Khair A, Garoff S, et al.
Langmuir . 2024 May; 40(19):10143-10156. PMID: 38690604
When placed in an ionic surfactant gradient, charged colloids will undergo diffusiophoresis at a velocity, = ∇ ln , where is the diffusiophoretic mobility and is the surfactant concentration. The...

Hashemi A, Gilman E, Khair A
Eur Phys J E Soft Matter . 2024 Apr; 47(4):28. PMID: 38676815
We develop a two-timing perturbation analysis to provide quantitative insights on the existence of temporal ratchets in an exemplary system of a particle moving in a tank of fluid in...

Kach J, Walker L, Khair A
Soft Matter . 2023 Nov; 19(47):9179-9194. PMID: 37997174
Application of an electric field across the interface of two fluids with low, but non-zero, conductivities gives rise to a sustained electrohydrodynamic (EHD) fluid flow. In the presence of neighboring...

Kailasham R, Khair A
Soft Matter . 2023 Oct; 19(40):7764-7774. PMID: 37791487
Numerical simulations are performed on the collective dynamics of active disks, whose self-propulsion speed () varies in time, and whose orientation evolves according to rotational Brownian motion. Two protocols for...

Kailasham R, Khair A
Phys Rev E . 2023 May; 107(4-1):044609. PMID: 37198791
The dynamics of a two-dimensional autophoretic disk is quantified as a minimal model for the chaotic trajectories undertaken by active droplets. Via direct numerical simulations, we show that the mean-square...

Lomeli-Martin A, Ernst O, Cardenas-Benitez B, Cobos R, Khair A, Lapizco-Encinas B
Anal Chem . 2023 Apr; 95(16):6740-6747. PMID: 37040369
Contemporary findings in the field of insulator-based electrokinetics have demonstrated that in systems under the influence of direct current (DC) fields, dielectrophoresis (DEP) is not the main electrokinetic mechanism responsible...

Yang A, McKenzie B, Yi Y, Khair A, Garoff S, Tilton R
J Colloid Interface Sci . 2023 Apr; 642:169-181. PMID: 37003011
Hypothesis: A concentration gradient of surfactants in the presence of polymers that non-covalently associate with surfactants will exhibit a continually varying distribution of complexes with different composition, charge, and size....

Phys Rev E . 2023 Mar; 107(2-1):024608. PMID: 36932547
The gravitational settling of oil droplets solubilizing in an aqueous micellar solution contained in a capillary channel is investigated. The motion of these active droplets reflects a competition between gravitational...
