“…The sun-situated cell limitations of the ZnO-based DSSC are supposedly heavily reliant on the diving duration of a ZnO film into an honing tone [14]. In contrast to previous studies, the transmitted ZnO-based DSSC demonstrated improved vitality in a shorter period of immersion time [15]. Another possible explanation for the enhanced capacity is the prolonged absorption due to the increased amount of shade particles adsorbed onto the ZnO surface.…”

XRD and SEM images of ZnO nanoparticles prepared by the precipitation method allow investigation of their morphology and morphological refinement. No contamination was observed in the XRD spectrum and SEM confirmed that the nanoparticles were wellcoordinated ZnO at 30 nm size. UV-Vis spectroscopy was used to tune the optical properties and they appeared not to be fixed at 3.34 eV. The band gap of semiconductor materials makes them competitive for solar cell applications. The O-rich stoichiometry measured by XPS may be a direct result of zinc deficiency. Therefore, ZnO nanoparticles were prepared to fabricate secretory solar cells (DSSCs). From the perspective of J-V, open circuit voltage (Voc), barrier thickness (Jsc), fill factor (FF) and efficiency (η) were not chosen as much as possible and the quality was calculated as 0.65V, 6.26mA. , 62.2% and 1.96% respectively at 100mW/cm2 .

“…After adsorption, most of the water molecules in this form of adsorbent are present as free water due to their entrapment in the cavities. Water is adsorbed onto an adsorbent, but only a tiny percentage of that water binds to functional groups on the surface of the adsorbent [19]. SEM images (Figure.…”

The production of innovative materials with improved features applicable in many domains is a key application of nanotechnology with far-reaching implications for modern society. Nanoparticle-based polymer composites are quickly becoming one of the most promising new materials, with potential uses spanning the chemical, physical, and biological sciences as well as engineering. Application of nanoparticle-based polymer composites for indoor air quality maintenance was discussed, as were their production, hybrid functionalization, and feasible synthesis procedures (filter membrane). The batch foaming procedure has been used to create foam from the thermoplastic polymer polypropylene (PP). Foaming is a blown process, where carbon dioxide is utilised as the blowing agent. Nanoparticles of titanium oxide (nano TiO2) are also used for reinforcement. Scanning electron microscopy (SEM) was utilised to investigate the NTPMs' surface morphology, while other physio-chemical characteristics were investigated by means of various analytical methods, including Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and thermo-gravimetric analysis (TGA). The adsorption isotherm and kinetics of water vapours were analysed to get insight into the water vapour adsorption characteristics of the NTPMs. The kinetics of adsorption pointed to a combination of intraparticle diffusion and liquid field driving processes for the transport of water vapours. Because of their high dehumidification effectiveness, synthetic NTPMs have the potential to replace many of the currently used traditional solid desiccant materials

“…Pr is an important rare earth element because it can be readily incorporated into the ZnO structure to increase electrical conductivity. This is due to the fact that doped rare earth ions can be employed as down shifting layers within the electronic band structure to enhance their electrical behaviour [10]. As a result, Pr can be readily incorporated into the ZnO structure to increase electrical conductivity.…”

Using a soft chemical process that involves nitrates and heat annealing, nanoparticles of undoped ZnO and praseodymium, aluminum-codoped ZnO may be produced. XRD, SEM with EDS, and FTIR analysis determine nanocatalyst structures, morphologies, and chemical bonding. PL and UV spectroscopy examines optical characteristics. The peak in the FTIR spectral line at 714 cm-1 in the study indicates M-O stretching in the samples and ZnO's interaction with the Pr and Al matrix. XRD patterns indicated prepared nanoparticles with nanosizes ranging from 40.07 to 38.65 to 36.84 to 38.87 to 39.91 nm. SEM analyzed nanoparticle size, shape, and interaction with the Pr and Al matrix. EDS determined NPs purity. UV-vis spectra of ZnO-Pr/Al nanocomposites showed UV absorption similar to ZnO nanoparticles. Doping ZnO with Pr and Al shrinks the bandgap and slows photogenerated electron-hole pair recombination without changing its crystalline structure.
