Mechano-lithography: stress anisotropy driven nematic order in growing three-dimensional bacterial biofilms
Changhao Li, Japinder Nijjer, Luyi Feng +3
Living active collectives have evolved with remarkable self-patterning ability to meet the physical and biological constraints for growth and survival. However, how complex multice…
Biofilms as self-shaping growing nematics
Japinder Nijjer, Mrityunjay Kothari, Changhao Li +7
Active nematics are the nonequilibrium analog of passive liquid crystals in which anisotropic units consume free energy to drive emergent behavior. Similar to liquid crystal (LC) m…
Interfacial Cavitation
Thomas Henzel, Japinder Nijjer, Chockalingam Senthilnathan +4
Cavitation has long been recognized as a crucial predictor, or precursor, to the ultimate failure of various materials, ranging from ductile metals to soft and biological materials…
Biofilm self-patterning: mechanical forces drive a reorientation cascade
Japinder Nijjer, Changhao Li, Qiuting Zhang +3
In growing active matter systems, a large collection of engineered or living autonomous units metabolize free energy and create order at different length scales as they proliferate…
