The investigation of dilute solution epitaxy of polyphenylene sulfide (PPS) has been carried out on a series of inorganic substrates, which cover a wide range of interatomic spacings, surface energies, and geometries. A variety of morphological arrangements of PPS on various substrates were observed. Both 〈100〉 and 〈110〉 epitaxial orientations were observed on monovalent alkali halides. While the 〈100〉 epitaxy is generally thought to grow upon nucleation on surface steps along the 〈100〉 direction, 〈110〉 epitaxy may also be nucleated on these surface steps. Changes in ionic lattice dimensions and ionic nature of the substrate have a substantial effect on the molecular packing of PPS and the resulting crystal orientations. Four new crystalline phases of PPS have resulted from the fold surface epitaxies on NaCl, KCl, KBr, and mica with favorable one- or two-dimensional lattice matching. This is a direct indication of the important role of lattice matching in inducing and defining the epitaxies and polymorphism of PPS.

Template Design

Template design on polymorph control, especially conformational polymorphs, is still in its infancy and the result of polymorph control is often accidental. A method of regulating the crystallization of conformational polymorphs based on the crystal structure similarity of templates and the target crystal form has been developed. Crystal structure similarity was considered to be able to introduce lattice matching (geometric term) with chemical interactions to regulate conformational polymorph nucleation. The method was successfully applied to induce the crystallization of DA7-II [HOOC–(CH2) n −2–COOH (diacids), named DAn, where n = 7, 9, 15, 17 and II represents the metastable polymorph] on the surface of DA15-II. An analogous two-dimensional plane – the (002) face of both DA15-II and DA7-II – was firstly predicted as the epitaxially attached face with similar lattice parameters and the strongest adsorption energy. The powder DA15-II template with the preferred orientation face in (002) presented much stronger inducing DA7-II ability than the template with other preferred orientation faces. The epitaxial growth of DA7-II on DA15-II through an identical (002) face was clearly observed and verified by the single-crystal inducing experiments. The molecular dynamics simulation results demonstrated that the strong interactions occurred between DA7 molecules and the (002) face of DA15-II. This method has been verified and further applied to the crystallization of DA7-II on the surface of DA17-II and DA9-II on the surface of DA15-II. This study developed a strategy based on structure similarity to regulate the conformational polymorph and verified the significant role of lattice matching and chemical effects on the design and preparation of templates.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.
