A (Macro)Molecular-Level Understanding of Polymer

Topology plays a critical role in dictating the properties of many materials. In recent years, with advances in synthetic and characterization techniques, substantial efforts have been made to decipher the topology of networks of interconnected molecules, i.e., polymer networks. Here, we discuss classical challenges in the field and review existing strategies to characterize and manipulate Anthony Cheetham - Google Scholar2002.

Control of In-MOF topologies and tuning of porosity

Jun 01, 2020 · Tuning of porosity in MOFs is best accomplished through isoreticular synthesis by employing organic linkers of varying dimensions and chemical functionalities, but with similar connectivity dispositions. In this scenario, the connectivity attributes of both linker and Mechanoresponsive Porosity in Metal-Organic Frameworks Mar 01, 2021 · The stabilization of metastable states in flexible MOFs is a key aspect to induce a shape-memory effect, which can be achieved by subtle changes in the characteristics of MOFs such as particles size or presence of defects. Chemical structure, network topology, and porosity effects on the mechanical properties of zeolitic imidazolate Nanofiber density determines endothelial cell behavior on Dec 01, 2013 · The upper surface is denser in fibers (entangled) than the lower surface that shows greater surface porosity. Human umbilical vein endothelial cells (HUVECs) were used to exploit how the microarchitecture (i.e., surface porosity, fiber network structure, surface topology, and fiber density) of bacterial cellulose pellicle surfaces influence

Pore Network Analysis of Resistivity Index for Water-Wet

Pore network analysis is used to investigate the effects of microscopic parameters of the pore structure such as pore geometry, pore-size distribution, pore space topology and fractal roughness porosity on resistivity index curves of strongly water-wet porous media. The pore structure is represented by a three-dimensional network of lamellar capillary tubes with fractal roughness features Synthesis of cyclic polymers and topology effects on their Dec 12, 2012 · Topology effects, which are the differences in physical and chemical properties arising from the shape of a polymer, have been extensively studied The effect of the pore topology on the elastic modulus of May 01, 2013 · Besides porosity and pore topology, the chemical bonding in the network of the OSG matrix, e.g., SiCCSi or SiOSi, also affects the E values of OSG materials.2 However, the normalized E/E s versus p trends obtained from FEM calculations are independent of the pore
