Of the three, NaPOF 6 is the only one that exhibits anomalous mechanical properties, with a very anistropic shear modulus and the existence of directions of negative Poisson's ratio (a phenomenon also called auxeticity), as displayed on Figure . This is clearly linked to its "wine-rack type" structure, showing how screening of materials by topology can be integrated into multi-scale high-throughput schemes for the identification of materials with targeted properties.
