Abstract Using chemical bath deposition (CBD) methods and various molarities, nanostructured CdS thin films were developed. XRD assured that these films were cubic polycrystalline, containing larger grains as the solution's concentration of cadmium ions increased. Dislocation density values dropped from 79.32 to 62.90 as a result, nevertheless. Also, the strain is lowered from 30.88 to 27.50. AFM results demonstrate that these films suffer a decrease in the value of average particle size, root mean square, and roughness with the molarity concentration. SEM images show CdS thin films at various molarities (0.10, 0.15, 0.20) M, indicating reduced More >

Abstract Cadmium sulfide (CdS) thin films are extensively utilized as a window layer in photovoltaic (PV) devices due to their high transmittance, suitable bandgap, and favorable electrical properties. This work presents a comprehensive performance analysis of CdS based thin films in PV applications, examining key factors such as optical, electrical, and structural properties. The bandgap (approximately 2.42 eV) allows effective photon transmission, reducing energy losses. Critical performance metrics, including film thickness, grain size, crystallinity, and interface quality with the absorber layer, are optimized to enhance charge separation and minimize recombination losses. The study highlights the balance More >

Abstract Cd_1-xPb_xSe (0≤ x ≤ 1) thin films with values of x = 0, 0.2, 0.4, 0.5 and 1, have been deposited by chemical bath technique for photovoltaic application. The deposition temperature, time and pH of the reactive solutions were 80℃, 150 min and 11 respectively. The XRD results confirmed the polycrystalline nature of all the films. It also showed that all the films exist in face centered cubic structures. There were no pure phases of CdSe and PbSe identified in the XRD results of the ternary compounds. The average grain sizes determined for each sample were… More >

Abstract This work used a sonication-aided approach to make Cadmium sulfide nanoparticles and Nitrogen-doped CdS nanoparticles. Doping Nitrogen into CdS NPs enhances the material's electrical, chemical, and structural properties by altering its surface area and functional sites. XRD, FTIR, SEM/EDX, TGA, UV-Vis, and PSA are used to evaluate the characteristic features of CdS NPs. The photovoltaic responses of the prepared CdS and CdS-N NPs were evaluated by electrochemical impedance and IV analysis. The obtained XRD data confirms that nitrogen doping significantly changes the crystal size of CdS NPs. The XPS spectrum depicts the presence of trace More >

Abstract This study focuses on optimizing practical synthesis to produce ultrafine CdS nanoparticles. Three separate chemical synthesis processes, namely microwave, wetchemical, and sonication methods, are used to generate CdS nanoparticles. Moringa oleifera leaf extract employed green syntheses of CdS nanoparticles are also performed for additional discussions. The generated CdS nanoparticles were subjected to a comparative assessment to identify the most effective processing method for synthesizing CdS nanoparticles. Even though the processing parameters were altered over their synthesis, the hexagonal structure was retained in the CdS nanoparticles. The observed results of CdS nanoparticles from XRD, SEM/EDX, and More >

Abstract Cadmium (Cd), a highly toxic heavy metal, represents a major global environmental threat due to its widespread dispersion through anthropogenic activities. Environmental Cd contamination poses significant risks to living organisms, including humans, animals, and plants. Certain plant species have evolved Cd hyperaccumulating capabilities to adapt to high-Cd habitats, playing critical roles in phytoremediation strategies. Here we review the biodiversity and biogeography of Cd hyperaccumulators, the underlying mechanisms of Cd uptake and accumulation, and the ecological impacts of hyperaccumulation. The major points are the following: twenty-four Cd hyperaccumulator species have been documented, with shoot Cd concentrations More >

Abstract Cadmium (Cd) contamination is a major environmental stressor that adversely affects crop germination and early development. This study assessed the impact of increasing Cd concentrations (0.125 to 1 g/L) on seed germination and early seedling growth in three bread wheat (Triticum aestivum L.) cultivars: Achtar, Lina, and Snina. The results revealed a clear dose-dependent inhibitory effect of Cd. Germination percentage (GP) significantly declined with increasing Cd levels, while mean germination time was progressively delayed, particularly at higher concentrations. Vigor index (VI) also showed significant reductions, reflecting compromised seedling establishment. Morphological traits, especially shoot and root lengths,… More >

Abstract Heavy metal pollution has become a pervasive environmental issue affecting numerous regions worldwide. Recently, there has been significant attention given to the application of nano-enabled technologies with the purpose of enhancing plant development and alleviating heavy metal stress. This study aimed to illustrate the potential of zinc oxide nanoparticles (ZnO-NPs) to enhance the morphological traits of D. huoshenense exposed to cadmium (Cd) stress. The chemical structure and elemental composition of the ZnO-NPs were characterised by a series of analytical methods, including X-ray diffraction, UV-Vis spectrometry, XPS, and TEM.

Abstract Plant invasion poses a serious environmental challenge to freshwater ecosystems. Heavy metal pollution and nutrient enrichment, particularly nitrogen (N) and phosphorus (P), are two additional critical environmental issues known to influence the growth of invasive plants. Notably, the N/P ratio in the environments is often inconstant; however, whether these variations can cause differential responses in invasive plants remains underexplored, despite its crucial importance for understanding plant invasiveness. In this study, we examined the effects of different N/P ratios (4:1, 16:1, 32:1, 64:1) on the growth of a widespread invasive plant Alternanthera philoxeroides in cadmium (Cd) polluted… More >

Abstract Cadmium sulfide was prepared by first turning it into a powder, which was then used to evaporate heat to create thin films. Additionally, the spray pyrolysis method was used to produce films of cadmium sulfide. A structural comparison using the crystallize size and lattice parameters. Furthermore for the prepared samples, an analysis of their optical characteristics was conducted through measurements of absorbance, transmission, and reflection, resulting in the determination of the energy gap.
