Onsager's variational principle in active soft matter. [PDF]
Onsagers variational principle (OVP) was originally proposed by Lars Onsager in 1931 [L. Onsager, Phys. Rev., 1931, 37, 405]. This fundamental principle provides a very powerful tool for formulating thermodynamically consistent models.

Splay-bend nematic phases of bent colloidal silica rods induced by polydispersity
Different shapes of molecules or particles can exhibit various liquid crystal phases. The authors report on an experimental discovery of a so called splay-bend nematic liquid crystal phase in a colloidal system of bent silica rods.

Observational constraints on soft dark energy and soft dark matter: challenging $Λ$CDM [PDF]
Soft cosmology is an extension of standard cosmology allowing for a scale-dependent equation-of-state (EoS) parameter in the dark sectors, which is one of the properties of soft materials in condensed-matter physics, that may arise either intrinsically or effectively.

Structural diversity in three-dimensional self-assembly of nanoplatelets by spherical confinement
Nanoplatelets can be used as anisotropic building blocks for constructing novel optoelectronic materials. Here, Wang et al. show a route of assembling nanoplatelets with controllable positional and orientational order in three dimensions facilitated by ...

Mesoscopic Modelling and Simulation of Soft Matter [PDF]
The deformability of soft condensed matter often requires modelling of hydrodynamical aspects to gain quantitative understanding. This, however, requires specialised methods that can resolve the multiscale nature of soft matter systems. We review a number of the most popular simulation methods that have emerged, such as Langevin dynamics, dissipative ...

Interplay between spherical confinement and particle shape on the self-assembly of rounded cubes
Colloidal nanoparticles self-assembled under spherical confinement can form a rich variety of structures. Here, the authors study the self-assembly of sharp and rounded nanocubes under such confinement, revealing the influence of particle and face ...

Acceleration of enzymatic catalysis by active hydrodynamic fluctuations
Cells are teeming with biochemical nano-machines whose vigorous activity generates strong hydrodynamic fluctuations. The authors revamp transition-state theory to account for the effect of this active noise and find that it may significantly accelerate ...

`Soft-Oxo-Metalates' (SOMs): A Very Short Introduction [PDF]
The field of polyoxometalates (POMs), in recent times, has entered a new arena of 'soft'-supramolecular interactions, crossing the molecular regime of covalent bonds. The structures resulting from such 'soft'-supramolecular interactions are much larger (~10-500 nm in diameter) showing soft-matter properties.

Complex multiphase organohydrogels with programmable mechanics toward adaptive soft-matter machines
Adaptive soft-matter machines are developed using the complex multiphase organohydrogels with multistable mechanical states. Many biological organisms can tune their mechanical properties to adapt to environments in multistable modes, but the current ...
