Swimming of bacterium \textit{Bacillus subtilis} with multiple bundles of flagella
Javad Najafi, Florian Altegoer, Gert Bange +1
We characterize the bundle properties for three different strains of \textit{B. subtilis} bacteria with various numbers of flagella. Our study reveals that, surprisingly, the numbe…
Flagellar number governs bacterial spreading and transport efficiency
Javad Najafi, M. Reza Shaebani, Thomas John +3
Peritrichous bacteria synchronize and bundle their flagella to actively swim while disruption of the bundle leads to tumbling. It is still not known whether the number of flagella…
Compaction of Quasi One-Dimensional Elastoplastic Materials
M. Reza Shaebani, Javad Najafi, Ali Farnudi +2
Insight in the crumpling or compaction of one-dimensional objects is of great importance for understanding biopolymer packaging and designing innovative technological devices. By c…
Packing of elastic wires in spherical cavities
N. Stoop, J. Najafi, F. K. Wittel +2
We investigate the morphologies and maximum packing density of thin wires packed into spherical cavities. Using simulations and experiments, we find that ordered as well as disorde…
