Here we report the deposition method of iron-oxide film. Synthesis, characterization and physico-chemical properties of oxide nanomaterials. Iron oxide thin film deposited onto the plain glass material. Iron oxide nanoparticles were synthesizes using chemical method by iron chloride and aqueous ammonia solution as a herald. In order to establish the composition of the iron oxide nanoparticles and its relation with size, the morphological, structural and magnetic properties of the prepared samples were investigated using DLS, SEM and TEM. The scanning electron microscopy (SEM) images show morphology of Iron oxide obtained by the above method and the growth of iron nano-rod of the as-deposited Iron-Oxide thin film. Iron oxide thin film is water dispersible, highly stable for more than 100 days at neutral pH with a size of less than 10-15 nm.

Background: Pyrroles are organic cyclic compounds with an extensive and fascinating chemistry. These compounds have a wide structural variety and they are an important basis in technological development as they can be used as drugs, dyes, catalysts, pesticides, etc. Therefore, the production of these heterocyclic compounds by efficient clean methodologies is a great achievement in contemporary chemistry. In this paper, we show recent green procedures in the synthesis of pyrrole derivatives such as Hantzsch, Knorr and Paal- Knorr syntheses, as well as new eco-friendly synthetic procedures with high efficiency and low environmental impact. Objective: This work focusses on the recent advances in the pyrrole synthesis using clean techniques like ultrasound (US), microwaves (MW), high speed vibration milling (HSVM), catalysts use, solvent replace and other methodologies applied to common reactions to obtain the pyrrole core which follow the green chemistry principles. Conclusion: The main challenge of Green Chemistry is to gradually eliminate the generation of hazardous or harmful materials or replace them with less toxic and safer ones. However, this process must be driven by scientific developments. Its application in the synthesis of heterocyclic compounds such as pyrrole derivatives involves multiple economic and social benefits due to the biological importance of these compounds and their direct impact on the pharmaceutical industry. Although many processes are still under investigation using novel methodologies of green activation such as microwaves, ultrasound and HSVM, as well as synthetic processes in continuous flow and processes at room temperature, promising results such as cost and waste reduction and greater efficiency are achieved.
