Slower swimming promotes chemotactic encounters between bacteria and small phytoplankton
Riccardo Foffi, Douglas R. Brumley, François Peaudecerf +2
Chemotaxis enables marine bacteria to increase encounters with phytoplankton cells by reducing their search times, provided that bacteria detect noisy chemical gradients around phy…
Anti-Diffusion in an Algae-Bacteria Microcosm: Photosynthesis, Chemotaxis, and Expulsion
Praneet Prakash, Yasa Baig, Francois J. Peaudecerf +1
In Nature there are significant relationships known between microorganisms from two kingdoms of life, as in the supply of vitamin B by bacteria to algae. Such interactions m…
Exogenous-endogenous surfactant interaction yields heterogeneous spreading in complex branching networks
Richard Mcnair, Fernando Temprano-Coleto, François J. Peaudecerf +4
Experiments have shown that surfactant introduced to a liquid-filled maze can find the solution path. We reveal how the maze-solving dynamics arise from interactions between the ad…
A single parameter can predict surfactant impairment of superhydrophobic drag reduction
Fernando Temprano-Coleto, Scott M. Smith, François J. Peaudecerf +3
Recent experimental and computational investigations have shown that trace amounts of surfactants, unavoidable in practice, can critically impair the drag reduction of superhydroph…
Migration and accumulation of bacteria with chemotaxis and chemokinesis
Theresa Jakuszeit, James Lindsey-Jones, François J. Peaudecerf +1
Bacteria can chemotactically migrate up attractant gradients by controlling run-and-tumble motility patterns. In addition to this well-known chemotactic behaviour, several soil and…
A theory for the slip and drag of superhydrophobic surfaces with surfactant
Julien R. Landel, François J. Peaudecerf, Fernando Temprano-Coleto +3
Superhydrophobic surfaces (SHSs) have the potential to reduce drag at solid boundaries. However, multiple independent studies have recently shown that small amounts of surfactant,…
Microbial mutualism at a distance: the role of geometry in diffusive exchanges
François J. Peaudecerf, Freddy Bunbury, Vaibhav Bhardwaj +4
The exchange of diffusive metabolites is known to control the spatial patterns formed by microbial populations, as revealed by recent studies in the laboratory. However, the matric…
Traces of surfactants can severely limit the drag reduction of superhydrophobic surfaces
François J. Peaudecerf, Julien R. Landel, Raymond E. Goldstein +1
Superhydrophobic surfaces (SHSs) have the potential to achieve large drag reduction for internal and external flow applications. However, experiments have shown inconsistent result…
Feeding ducks, bacterial chemotaxis, and the Gini index
Francois J. Peaudecerf, Raymond E. Goldstein
Classic experiments on the distribution of ducks around separated food sources found consistency with the `ideal free' distribution in which the local population is proportional to…
