New insights into the crystallization of polymorphic materials: from real-time serial crystallography to luminescence analysis

Abstract

This article unravels reaction conditions governing the formation of polymorphic structures in solution down to the single particle level applying, for instance, unprecedented real-time serial crystallography measurements during a synthesis process.

α-Ag2S nanoparticles: low-temperature syntheses, crystallisation pathway, and first operando luminescence measurements for sodium-ion battery applications

“…For this purpose, changes in turbidity and ionic conductivity during the reaction were tracked, and in situ measurements of synchrotron-based X-ray diffraction, UV/Vis transmission, and infrared spectroscopy were performed under real reaction conditions. 43 This work also demonstrates the feasibility of using operando luminescence measurements to track structural changes in emitting-battery electrodes. This feature is particularly important because of the large number of luminescent battery electrodes and because such operando measurements can be performed in conventional university laboratories.…”

Challenges and Opportunities of Implementing Data Fusion in Process Analytical Technology—A Review

“…The volume flow and moisture content of air can also be critical parameters in the case of fluidized bed granulation, drying, or film coating. The pH and conductivity value of the medium can be measured with in-line electrode probes during chemical reactions of crystallization [ 30 ].…”

In Situ Monitoring of Particle Formation with Spectroscopic and Analytical Techniques Under Solvothermal Conditions

“…Green et al studied the formation of silica nanoparticles through the base‐catalyzed hydrolysis of tetraethylorthosilicate (TEOS) in methanol and ethanol using a combination of 29 Si NMR, SAXS, and DLS measurements . Luminescence studies have been coupled to in situ X‐ray diffraction measurements to study the formation of various metal complexes and polymorphic materials , and to follow metal‐ligand exchange processes in situ .…”
