DRIVEN TOPOLOGICAL TRANSITIONS IN ACTIVE NEMATIC FILMS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 08 settembre 2020 The topological properties of many materials are central to their behavior. In intrinsically out-of-equilibrium active materials, the dynamics of topological defects can be particularly important. In this paper, local manipulation of the order, dynamics, and topological properties of microtubule-based active nematic......

SPECTRAL ENERGY ANALYSIS OF BULK THREE-DIMENSIONAL ACTIVE NEMATIC TURBULENCE

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), sab 15 agosto 2020 We perform energy spectrum analysis of the active turbulence in 3D bulk active nematic using continuum numerical modelling. Specifically, we calculate the spectra of two main energy contributions—kinetic energy and nematic elastic energy—and combine this with the geometrical analysis of the......

PATIENCE IS A VIRTUE: SELF-ASSEMBLY AND PHYSICO-CHEMICAL PROPERTIES OF CELLULOSE NANOCRYSTAL ALLOMORPHS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 11 agosto 2020 Cellulose nanocrystals (CNCs) are bio-based rod-like nanoparticles with a quickly expanding market. Despite the fact that a variety of production routes and starting cellulose sources are employed, all industrially produced CNCs consist of cellulose I (CNC-I), the native crystalline allomorph of......

A BLEND OF STRETCHING AND BENDING IN NEMATIC POLYMER NETWORKS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 04 agosto 2020 Nematic polymeric networks are (heat and light) activable materials, which combine the features of rubber and nematic liquid crystals. When only the stretching energy of a thin sheet of nematic polymeric network is minimized, the intrinsic (Guassian) curvature of the shape......
