8. Crystallization in Polymorphic Systems:  The Solution-Mediated Transformation of β to α Glycine

Author

Ferrari, E. S., Davey, R. J., Cross, W. I., Gillon, A. L., and Towler, C. S.

Abstract

The crystallization and subsequent polymorphic transformation from the β to the α form of glycine has been studied using optical microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy techniques. The crystal structure and morphology of β glycine have been determined, and the influence of solvent, solubility, and process scale on its solvent-mediated transformation to the α form was quantified. It is concluded that for the low solubility environments used in this study, the rate-determining step in the transformation process is the dissolution rate of the metastable β polymorph.

Abstract

Nitrogen can enter the water cycle through atmospheric depositions on ground and water surfaces, leakages from point and diffuse sources (i.e., sewage treatment plants or sewage systems, fertilizer and manure applications), and erosion processes affecting nitrogen rich soils (EEA, 2005). However, integrating all nitrogen forms, processes and scales is still a major challenge for the understanding and the management of the nitrogen cycle.

14. Non-invasive study of natural dyes on historical textiles from the collection of Michelangelo Guggenheim.

Author

de Ferri L, Tripodi R, Martignon A, Ferrari ES, Lagrutta-Diaz AC, Vallotto D, and Pojana G

Abstract

A selection of historical textile fragments from the Venetian art dealer Moisè Michelangelo Guggenheim collection, ranging from XV to XVIII century, has been investigated by means of non-invasive techniques in order to reveal the coloring materials. Imaging was preliminarily used to visually investigate the selected artwork fragments in order to investigate their structure and conservation conditions; Fiber Optics Reflectance Spectroscopy (FORS) allowed recognizing the main natural dyestuffs, such as indigotin and anthraquinones-based compounds, except the yellow ones, difficultly identifiable when using this non-invasive technique. Collected spectroscopic data have been also elaborated by using a clustering algorithm that permitted to group collected spectra on the basis of similar properties and evidencing their inflection point wavelength as the most influencing feature., (Copyright © 2018 Elsevier B.V.

16. Interatomic potential parameters for potassium tetrachlorozincate and their application to modelling its phase transformations.

Author

Ferrari ES, Roberts KJ, Thomson GB, Gale JD, and Catlow CR

Abstract

An empirical fitting procedure is applied to derive interatomic potential parameters for a model phase transition system, namely potassium tetrachlorozincate (K(2)ZnCl(4)). The derived potential is found to reliably model the known crystallographic structure for the ferroelectric and paraelectric phases of this compound. Potential transferability is demonstrated by applying the parameters derived to the optimization of the known molecular structure for a similar inorganic system (rubidium tetrachlorozincate).
