“…Atmospheric air was used as carrier gas with 1 mbar pressure. Thickness of all the films was constantly maintained at 500 7 10 nm and confirmed through weight difference method [46]. X-ray diffractometer (D8 Focus, Bruker, Germany) and field emission scanning electron microscope (FE-SEM, 6701 F, JEOL, Japan) were used to study the impact of Co-doping on the structural and morphological properties of nanostructured ZnO thin films.…”

“…electrical, morphological and optical can be optimized by variation in precursor, solvent medium, etc. Electrical conductivity was strongly affected by the modulation and solvent medium [15]. Further, cellulose extraction from various vegetables and fruit pomace has beenachieved by the novel fractionation process.…”

Cellulose based nanofilms have large applications in biomedical and related fields due to their antimicrobial properties. Their applicability depends upon purity of cellulose, composition, and structural properties of films. The nanofilms of cellulose extracted from Water Hyacinth (Eichhornia crassipes) and Roselle (Hibiscus Sabdariffa) plant possesses excellent properties for biomedical applications due to their biological origin and ZnO or other metal loading properties. Microwave assisted physical separation of cellulose provided excellent films formation properties and ZnO loading compared without any chemical traces. The presence of chemical impurities to affects structural, morphological properties and contact angle. It affects the biomedical applicability of cellulose based films. The microwave-based extraction was further assisted by use of polyethylene glycol with molecular weight 600, which increases the solubility and extractability of cellulose to 90 %. Formed films showed higher contact angle and hydrophobicity. This increased hydrophobicity of cellulosic nanofilms showed enhanced antimicrobial activities towards gram-negative and gram-positive bacteria by water hyacinth nanofilms. Thus, microwave-based synthesis of cellulose nanofilms resulted into enhanced microbial activities.

A thin nanofilm was achieved using water lettuce (Pistia Stratiotes) plant extract. Characterization of the nanofilm was done tounderstand the thickness and morphology of the resulting film. The addition of the polyethylene glycol 400 was suitable for the proper dissolution of cellulose. Characterization and study of morphological structure of cellulose fibers was done by using scanning electron microscopy(SEM). The resulting data of SEM analysis was acceptable for water lettuce extract, as content of cellulose fibers was more.
