We discuss the impact of strong absorption for thermal neutrons on data analysis and compare absorption corrections in the GSAS and MAUD Rietveld codes for texture and structural parameter refinement. Diffraction data were collected on the neutron powder diffractometer HIPPO at LANSCE from dysprosium and erbium, which are moderate to strong absorbers for thermal neutrons with absorption cross-s...

Rietveld analyses of the synchrotron X-ray diffraction data for various cation forms of zeolite ECR-1 have demonstrated framework Al zoning, which parallels the alternation of Al-rich maz and Al-poor mor layers. This can be further supported by notable differences in the average bond valence of its 10 crystallographically distinct tetrahedral sites.

My aim is to extend the notion of gray zone, presented by Claire Bishop in her 2018 essay, Black Box, White Cube, Gray Zone, through that skilled intentionality, proposed Erik Rietveld and colleagues (Rietveld, Denys, Van Westen, 2018) field embodied cognitive science. Starting, thus, from an ecological-enactive approach cognition, I will present co-presence which try shed light on how we are a...
