Metal–organic polyhedra (MOPs) are intrinsically porous cage-like structures; however, they frequently display low porosity due to their agglomeration caused by solvent exchange and removal, which results in the blockage of pore windows. This study presents unprecedented single-crystal-to-single-crystal transformation a cuboctahedral MOP-OH ([Cu24L24], H2L = 5-hydroxybenzene-1,3-dicarboxylic ac...

the main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. due to the above mentioned problems and in order to solve and minimize them nasal packing, na...

In a graph G = (V,E), a subset $S⊂V$ is said to be an open packing set if no two vertices of S have a common neighbour in G. The maximum cardinality of an open packing set is called the open packing number and is denoted by $ρ^{o}$. This paper further studies on this parameter by obtaining some new bounds.

Abstract To address the challenge of reconstructing or designing three-dimensional microstructure nanoporous materials, we develop a computational approach by combining random closed packing polydisperse spheres together with Laguerre–Voronoi tessellation. Open-porous cellular network structures that adhere to real pore-size distributions materials are generated. As an example, ?-carrageenan ae...

The field of unsaturated soil mechanics has recently seen the introduction pore network models, which attempt to replicate void structure porous materials. They are robust physically-based simulation tools and have been used simulate constitutive relationships like water retention curves (SWRC) hydraulic conductivity functions. This work aims present a networkmodeling approach for predicting hy...

In a recent paper [Yiotis et al., Phys. Rev. E 85, 046308 (2012)] we developed a model for the drying of porous media in the presence of gravity. It incorporated effects of corner film flow, internal and external mass transfer, and the effect of gravity. Analytical results were derived when gravity opposes drying and hence leads to a stable percolation drying front. In this paper, we test the t...
