TLDR
In this paper, the nucleation and growth of ZnO nanostructures in liquid media by classical and non-classical (i.e., particle-based) crystallization pathways are discussed.Abstract:
Among all the functional materials, ZnO plays an outstanding role in terms of chemical and physical properties, but also in terms of morphological variety and the number of reported synthesis approaches. Complex shapes and hierarchical architectures make ZnO a perfect example to study chemical and crystallization mechanisms. In this review article, we will discuss the nucleation and growth of ZnO nanostructures in liquid media by classical and non-classical (i.e., particle-based) crystallization pathways. We elaborate the chemical conditions and parameters that are responsible for the occurrence of one or the other pathway.read more

Synthesis Approaches of Zinc Oxide Nanoparticles: The Dilemma of Ecotoxicity
TL;DR: In this article, a comparison between pollutants and hazards spawned from chemical, physical, and biological methods used for the synthesis of zinc oxide nanoparticles (ZnO) is presented, where the emphasis is on devising eco-friendly techniques for ZnO especially biological methods which are comparatively less hazardous and need to be optimized by controlling the reaction conditions in order to get desired yield and characteristics.
