“…Sn–Cu lead-free solder is one of the potential solders in the solder industry due to its various advantages. , There are some literatures based on the synthesis of Sn–Cu lead-free solder from alkaline as well as acidic bath through the electrodeposition method. ,− There are some literatures available regarding the growth analysis of the thin film of different alloys rather than Sn–Cu by employing different techniques, such as computational modeling, electrochemical analysis, , and microstructural characterization. − This present work highlights the nucleation and growth mechanism of Sn–Cu solders synthesized via pulsed electrodeposition at different current densities. Although it is near-eutectic, the Cu 6 Sn 5 phase is not considered in this mechanism due to its very low volume fraction, and the nucleation and growth of only the Sn matrix are presented.…”

The present study highlights the changes in morphology in a Sn matrix during pulsed electrodeposition of a Sn−Cu near-eutectic alloy with varying current density in an acidic electrolyte. 3D image construction has been employed using SHAPE V7.3; Shape Software: Kingsport, Tennessee, USA to replicate the shape of grown crystals and analyze the results. It is observed that the growth morphology changes with the introduction of high index planes at higher current densities. Furthermore, a growth pattern occurs with high index planes formed from a stepped structure in low index planes. There has been a change in growth direction from ⟨001⟩ to ⟨110⟩ at higher current densities. At very high current densities, sympathetic or secondary nucleation is observed.

“…The OA growth, frequently the early growth stage of nanomaterials, has a profound influence on the final microstructure and properties of materials. 26,27 Several excellent reviews have summarized the OA phenomenon 28,29 or described kinetic models 30,31 involving this mechanism. However, correlation of the different OA behaviors described by different models as well as elucidation of the impact of surface capping agents requires both a summary of recent developments and further analysis of kinetic data.…”

Crystal growth mechanism, kinetics, and microstructure development play fundamental roles in tailoring materials with controllable sizes and morphologies. Oriented attachment (OA) involves the spontaneous self-organization of adjacent nanocrystals, resulting in crystal growth by addition of solid particles that share a common crystallographic orientation. It is common for crystal growth to occur by more than one mechanism simultaneously, such as OA and coarsening. This complexity leads to the difficulty in studying the OA growth mechanism. Here, we briefly review progress in kinetic models involving OA and the impact of this mechanism on materials science. We concentrate mostly on recent findings that relate different OA behaviors to surface chemistry and growth conditions, aiming to elucidate this crystal growth mechanism. To explore OA-limited growth, the influence of the Ostwald ripening (OR) mechanism needs to be known and quantified. The introduction of capping ligands has been reported to play multiple roles, including i) promoting or inhibiting aggregation and thus influencing OA growth, or ii) hindering OR from occurring and thus facilitating OA. A detailed survey of nanocrystal growth kinetics under the effect of surface adsorption is presented and summarized.

This review provides a background on the structure and properties of ZnO nanostructures. ZnO nanostructures are advantageous for many applications in sensing, photocatalysis, functional textiles, and cosmetic industries, which are described in this review. Previous work using UV Visible (UV–vis) spectroscopy and scanning electron microscopy (SEM) for ZnO nanorod growth analysis in‐solution and on a substrate for determination of optical properties and morphology is discussed, as well as their results in determining the kinetics and growth mechanisms. From this literature review, it is understood that the synthesis process greatly affects nanostructures and properties; and hence, their applications. In addition, in this review, the mechanism of ZnO nanostructure growth is unveiled, and it is shown that by having greater control over their morphology and size through such mechanistic understanding, the above‐mentioned applications can be affected. The contradictions and gaps in knowledge are summarized in order to highlight the variations in results, followed by suggestions for how to answer these gaps and future outlooks for ZnO nanostructure research.
