Nematicity is an exciting material property, which in complex fluids relies on the orientational ordering of passive or active (self-driven) building blocks. Here, I present the results of my research on microfluidic structures in passive and active nematic fluids that are characterised by geometri ...

V diplomski nalogi smo predstavili nekaj pristopov, ki nam pomagajo izboljšati kakovost kode ter načine, kako se izogniti napakam in kako jih najti. Vsak pristop smo opisali, predstavili prednosti in slabosti pri uporabi le-teh in prikazali nekaj praktičnih primerov. Omejili smo se na 4 pristope in ...

Generation of flow is an important aspect in microfluidic applications and generally relies on external pumps or embedded moving mechanical parts which pose distinct limitations and protocols on the use of microfluidic systems. A possible approach to avoid moving mechanical parts is to generate flow ...

Analytic formulations of elementary flow field profiles in weakly anisotropic nematic fluid are determined, which can be attributed to biological or artificial micro-swimmers, including Stokeslet, stresslet, rotlet and source flows. Stokes equation for a nematic stress tensor is written with the Gre ...

Liquid crystals (LCs) can host robust topological defect structures that essentially determine their optical and elastic properties. Although recent experimental progress enables precise control over nematic LC defects, their practical potential for information storage and processing has yet to be e ...

Active matter is naturally out of equilibrium which results in the emergence of diverse dynamic steady states, including the omnipresent chaotic state known as the active turbulence. However, much less is
known how active systems dynamically depart out of these configurations, such as get excited o ...

Compared to isotropic liquids, orientational order of nematic liquid crystals makes their rheological properties more involved, and thus requires fine control of the flow parameters to govern the orientational patterns. In microfluidic channels with perpendicular surface alignment, nematics disconti ...

Active nematics contain topological defects that (under sufficient activity) move, create, and annihilate in a chaotic quasi-steady state, called active turbulence. However, understanding active defects under confinement is an open challenge, especially in three dimensions. Here, we demonstrate the ...

Swimming in low-Reynolds-number fluids requires the breaking of timereversal symmetry and centrosymmetry. Microswimmers, often with asymmetric shapes, exhibit nonreciprocal motions or exploit nonequilibrium processes to propel. The role of the surrounding fluid has also attracted attention because v ...
