PICRAT

EdTechnica, 2022
PICRAT is a technology integration model for teacher education intended to assist teachers in improving their classroom practices. PICRAT (Kimmons et al., 2020; see Figure 1) has two parts representing two guiding questions: PIC and RAT. The PIC part responds to the question “What is the student’s relationship to the technology” with one of three ...

l-Methioninium picrate

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2015
Single crystals of l-methioninium picrate were obtained by evaporation of aqueous solution containing equimolar quantities of each component. l-Methioninium picrate crystallizes in the monoclinic system (space group P21, Z=2). The asymmetric unit contains one l-methioninium cation and one picrate anion.

l-Nitroargininium picrate

Journal of Molecular Structure, 2015
L-Nitroargininium picrate has been obtained from an aqueous solution containing equimolar quantities of l-nitroarginine and picric acid by slow evaporation. Single crystal was grown by evaporation method. Crystal structure was determined at room temperature. The salt crystallizes in monoclinic crystal system (space group P21).

L-Prolinium picrate and 2-methylpyridinium picrate

Acta Crystallographica Section C Crystal Structure Communications, 2006
In the structure of L-prolinium picrate, C5H10NO2+.C6H2N3O7-, the Cgamma atom of the pyrrolidine ring has conformational disorder. Both the major and minor conformers of the pyrrolidine ring adopt conformations intermediate between a half-chair and an envelope.
