“…This is due to the Mn doping which has a smaller ionic radius that causes bigger strain in the lattice. The positive strain implies an expansion in the system due to this doped system shows higher crystallite size values which were calculated by W-H method as compared to the crystallite size calculated by Scherrer's method [27,28]. The volume of unit cell enhances for Mn doping due to the positive strain that produces expansion in the lattice system.…”

“…The band gap of 4% Mn-doped ZnO is small as compared to the band gap of Pure ZnO which outlines the redshift. This is due to the quantum confinement of electron in one dimensional Mn-doped ZnO nanoflowers [28]. The efficiency of photocatalysis depends upon the harvested region of the solar spectrum by ZnO nanomaterials and the rate of electron-hole pair generation.…”

Pure and Mn-doped ZnO nanoflowers were successfully synthesized by the hydrothermal technique. Doping of Mn into ZnO lattice exhibits formation of oxygen vacancies and surface modifications into ZnO lattice was investigated by XPS spectra and AFM analysis. During the photocatalytic performance, vacancies create the trap centers for photogenerated electrons hence the electron-hole recombination is effectively inhibited. These formed oxygen vacancies along with enhanced surface area are due to Mn doping, resulted in effective photodegradation of methylene blue solution under solar light irradiation. The degradation efficiency for methylene blue dye exceeds 82% after 120 min under solar light irradiation, also the catalytic performance of Mn-doped ZnO nanoflowers retains even after 4 cycles.

“…Gattu et al reported fabrication of Au-nanoparticles doped with SnO 2 with remnant water obtained from Cicer arietinum L. extract, a type of Bengal gram beans through a green chemical approach. [246] The extract consists of pectin polysaccharide, which could be pledged for the nanoparticles synthesis. These gold-doped biosynthesized SnO 2 nanoparticles were further coated on glass plate to prepare thin films.…”

Biopolymers are considered as a favorable group of substances with a broad array of applications, of which biomedical field stands out. The interesting features of biopolymers such as low‐cost, non‐cytotoxicity, hydrophilicity, biodegradation and biocompatibility make them promising and excellent feedstock to be used in implantable devices. The bounteous reactive functional groups in the backbone structure of polysaccharides and its derivatives could be utilized to develop hydrogels, nano‐composite and 3D scaffolds with appealing structures and desired features, leading to promising research attention towards biomedical fields. The present review describes the foremost properties as well as potential of different biopolymers, and their composites for application in implantable biomedical systems. This work may introduce readers about the comprehension of state‐of‐the‐art advances, real present challenges along with the future anticipation of eco‐friendly and biomimetic techniques for the modification of biopolymeric materials to improve their biomedical applications.

“…Nitrogen dioxide is another toxic pollutant affecting human health including respiratory infections. Gattu and coworkers [128] were able to synthesize Au doped SnO 2 NPs using the gram beans waste extracts. The AuNPs were found to be a highly sensitive detector for nitrogen dioxide and reported efficient for monitoring the level of nitrogen dioxide [128].…”
