Microstructural analysis topology

Fig. 6. Topological analysis of 2-AG distribution in different layers of rat hippocampus. Selected microstructure from hippocampus was laser-cut under the microscope (A) and analyzed using a state-of-the-art microflow LC/MS system. A heat map was generated to show topological differences in 2-AG levels (B).

The theoretical equations presented above can be used to interpret stress-strain measurements in uniaxial extension and thus to fully characterize elastomeric networks. In this regard, equations (124) and (125) are of particular interest since they relate the parameter k, quantifying the entanglement constraints in the Flory and Erman model, to the polymer microstructure and conformational properties and to the network topology. An illustrative analysis of stress-strain data due to Queslel, Thirion and Monnerie is reported below. 

It is possible to carry out particle shape analysis and topological characterisation of granular textures in microstructures. The technique was used to study unreacted cement (Holzer et al. 2006) impregnated with Wood s metal (Bi 50%, Pb 25%, Sn 12.5%, Cd 12.5% melting point 70°C) in order to prevent charge effects. Polishing was as standard for preparing...
