Active screws: Emergent active chiral nematics of spinning self-propelled rods
Physical Review ResearchSeveral types of active agents self-propel by spinning around their propulsion axis, thus behaving as active screws. Examples include cytoskeletal filaments in gliding assays, magnetically driven colloidal helices, and microorganisms such as the ...

Chemistry – A European Journal, Volume 32, Issue 36, 24 September 2026.Robust, bio‐derived, and freestanding films based on cellulose nanocrystals (CNCs), covalently decorated with achiral fluorophores, transduce shape chirality and supramolecular helicity into near‐white circularly polarized luminescence (CPL). With composites covering the visible spectrum, near‐white, right‐handed CPL with high luminescence dissymmetry (

Anomalous dynamics of a passive droplet in active turbulence
Nature CommunicationsMotion of a passive deformable object in an active environment serves as a representative of both in-vivo systems such as intracellular particle motion in Acanthamoeba castellanii, or in-vitro systems such as suspension of beads inside dense swarms of ...

Nanophotonics, Volume 15, Issue 17, 11 September 2026.We demonstrate a VO2‐based transmissive reconfigurable intelligent surface for indoor millimeter‐wave communication. The TRIS replaces conventional PIN and varactor diodes with geometrically tailored VO2 switches, enabling transmitted phase control through phase‐transition‐based switching.

Active microrheology of fluids with orientational order
Condensed Matter PhysicsWe study the dynamics of a driven spherical colloidal particle moving in a fluid with a broken rotational symmetry. Using a nematic liquid crystal as a model, we demonstrate that when the applied force is not aligned along or perpendicular to the ...
