“…The biosynthesized nanoparticles are confirmed by the absorption spectra at 452nm by UV-Visible spectroscopy.It is the preliminary confirmation for formation of silver nanoparticles ( Figure 2). The result are similar to earlier reports in the literature (Vijayakumar et al, 2018;Leema Rose et al, 2017;Klaus et al, 1999;Muchanyereyi-Mukaratirwa Netai et al, 2017;Ahmed Set al, 2016). The FTIR analysis is used to confirm the extract is the cause for formation of silver nanoparticles and capping of extract molecules by the functional group present in the extract.…”

Objective: Now a day's cost effective and environmentally friendly technologies for nano material synthesis have gaining attention in biosynthesis of nanoparticles. have been used traditionally in Tamilnadu for Cassia auriculata various ailments. The present study contains by using silver nanoparticles are biosynthesized from Cassia auriculata aqueous silver nitrate solution. In 1mM silver nitrate solution plant flower extract is added Material and Methods: after 12hrs the color change from dull yellow to blackish brown confirms the formation of nanoparticles. It is further confirmed and characterized through UV-VIS, FTIR, SEM, EDAX and XRD instruments. Results and conclusion: A peak at 452 nmconfirms the formation of nanoparticles, FTIR peaks confirm the capping of plant biomoleculs on silver nanoparticles, EDAX result confirmed reduction of silver nitrate to silver ions, SEM exhibits morphology and size of nanoparticles, XRD reveals the formation cubic structure. The nanoparticles proved to be it posses antibacterial and antifungal properties. In this study antibacterial and antifungal potentials are compared with standard chloramphenicol and nystatin.

“…In fact, surface modification by surfactants has proven beneficial for heading off aggregation, and doping is expected to decrease the energy gap and shift the required excitation wavelength from the UV range to the visible light spectrum [13][14][15][16]. Therefore, the doping of the structure of ZnO nanostructures the usage of appropriate dopants is predicted to improve their affectivity in the photo degradation of organic pollutants and additionally in antibacterial activities [17][18][19][20][21][22][23][24].…”

A systematic investigation on the structural, optical and photo catalytic properties of pure and tungsten (W) doped ZnO nanoparticles synthesized by sonochemical method followed by increased calcinations temperature is presented here. The X-ray diffraction (XRD) analysis of these samples showed the formation of phase pure nanoparticles with wurtzite ZnO structure. The Ultra violet (UV-Vis) optical studies showed a blue shift in the absorbance peak spectrum with increasing the doping concentration of Tungsten. The FESEM imaging analysis reveals the spherical like morphology with agglomeration and clearly depicts the calcination temperature plays an important role in morphological formation and variation in agglomeration of the prepared ZnO nanostructures. The Rhodamine B (RhB) decomposition rate of the synthesized pure ZnO and tungsten doped ZnO nanoparticles were studied under the UV region. In the UV region, synthesized pure ZnO and Tungsten doped ZnO decomposed RhB dye. However, the RhB decomposition rate obtained using pure ZnO was much lower than by doped ZnO.

“…Nanoparticles have enchanted prestigious awareness due to their individual chemical and physical properties, which are dissimilar from those of either the bulk materials or single atoms. Nanoparticles are of great awareness for many technical applications in dependent physical properties like fundamental research [1][2][3][4]. In recent days, many scholars have focused on metal oxide due to their applications in several areas of research, peculiarly in optoelectronic and other applications, including phototransistors, solar cells, transparent electrodes, photodiodes and gas sensors [5][6].…”

Cadmium oxide (CdO) nanomaterial has been synthesized by electrochemical method which is simple and inexpensive method. The synthesized cadmium oxide nanomaterial was used as a catalyst for the photocatalytic degradation of acetic acid, formic acid and oxalic acids under varies experimental conditions by volumetric method. The synthesized nanomaterials were characterized by various techniques such as UV-Visible spectroscopy, SEM-EDAX, FT-IR spectrum and X-ray diffraction studies. The UV-VIS spectroscopy study revealed that the band gap energy of cadmium oxide nanomaterials to be 2. 85 eV Tauc plot. The structure of cadmium oxide was found to be cubic structure and crystal size was found to be 32 nm which was confirmed from XRD data. SEM reports showed that the cadmium oxide nanomaterials have regular spherical shape and uniform size. The presence of cadmium and oxygen in the nanomaterial is confirmed from the EDAX spectrum. FT-IR spectra reveal the presence of characteristic band corresponds to Cd-O mode. The photocatalytic activity of the synthesized cadmium oxide nanomaterial was examined by the kinetics of photodegradation of carboxylic acids by volumetric method by using NaOH solution. Taft LFER was tested the isokinetic temperature β was calculated for oxidation of carboxylic acids. The antibacterial activity of cadmium oxide nanomaterial was investigated.
