The regulation of light-harvesting in photosynthesis under conditions of varying solar light irradiation is essential for the survival and fitness of plants and algae. It has been proposed that rearrangements of protein distribution in the stacked grana region of thylakoid membranes connected to changes in the electronic pigment-interaction play a key role for this regulation. In particular, ca...

— We consider the problem of constructing dense lattices in Rn with a given non trivial automorphisms group. We exhibit a family of such lattices of density at least cn2−n, which matches, up to a multiplicative constant, the best known density of a lattice packing. For an infinite sequence of dimensions n, we exhibit a finite set of lattices that come with an automorphisms group of size n, and ...

Dense particle packing in a confining volume remains a rich, largely unexplored problem, despite applications in blood clotting, plasmonics, industrial packaging and transport, colloidal molecule design, and information storage. Here, we report densest found clusters of the Platonic solids in spherical confinement, for up to [Formula: see text] constituent polyhedral particles. We examine the i...

By means of extensive coupled molecular dynamics-lattice Boltzmann simulations, accounting for grain dynamics and subparticle resolution of the fluid phase, we analyze steady inertial granular flows sheared by a viscous fluid. We show that, for a broad range of system parameters (shear rate, confining stress, fluid viscosity, and relative fluid-grain density), the frictional strength and packin...

Dense packing of equal circles on a sphere is investigated. A systematic algorithm, the Minimum-Zenith Method (MZM), is proposed in this report. Started from a proper initial configuration, a circle is sequentially packed one by one so that the zenith angle is as small as possible. It is necessary to fix the size of the circle and some initial configuration. Circle configurations we examined ha...

We study the cluster structures of one-patch colloidal particles generated by droplet evaporation using Monte Carlo simulations. The addition of anisotropic patch-patch interaction between the colloids produces different cluster configurations. We find a well-defined category of sphere packing structures that minimize the second moment of mass distribution when the attractive surface coverage o...

The title compound was synthesized and characterized by IR NMR spectroscopy single crystal X-ray diffraction. analysis of the packing its analog, bearing a nitro group instead nitrile one, allowed direct comparison two common explosophoric groups: CN NO2. By using ΔOED-based densification approach, it is shown that lighter in mass, less dense, participates intermolecular bonding to lesser exten...
