“…The main components in all of the three structures were Mg, Si, Na, Cl, O, and C. In more detail, the Mg 1s spectra of all samples revealed a single chemical state of magnesium at 1303.1, 1303.5, and 1303.0 eV for seed, injection, and membrane experiments, respectively. These peaks indicated the presence of Mg–O bond. , The shift in the binding energy of Mg 1s was attributed to the hydroxylation of surface and formation of Mg(OH) 2 component. , When comparing the intensities of the magnesium (Mg) peaks, it became evident that the magnesium content of the structure obtained from the membrane experiment was higher compared to the other two solids formed in the seed and injection experiments. This outcome was anticipated, as the chemical garden developed in the membrane growth was formed on the side adjacent to the magnesium chloride solution, indicating a naturally elevated Mg content.…”

Chemical gardens are an exciting area of selforganized precipitation structures that form nano-and micro-sized structures in different shapes. This field has attracted great interest from researchers due to the specific characteristics and potential applications of these structures. Today, research on chemical gardens has provided deeper information regarding the formation mechanisms of these structures, and several techniques have been developed for chemical garden growth. However, they all show different growth patterns and lead to the formation of structures with a variety of morphological, chemical, or physical properties. This study aimed to evaluate the effects of different production techniques on chemical garden growth, taking into consideration the growth patterns, morphology, microstructure, and chemical composition. The chemical garden structures obtained in seed and injection experiments, two common methods, showed highly similar surface structures, void formation, and chemical composition. The membrane growth method has a small number of applications; thus, it was comprehensively evaluated to add new insights to the existing limited data. It produced the most stable and standard structures in a flat sheet-like shape and showed different morphologies than those observed in other two methods. Overall, this study presented significant results about the effect of growth techniques on chemical garden structures and similar systems.
