Synthesis and properties of nano-cadmium oxide and its size-dependent responses by barley plant.

Present study included technological methods that made it possible to synthesize CdO nanoparticles and carry out their qualitative and quantitative diagnostics, confirming the as-prepared CdO nanoparticles (NPs) were spherical and had a size of 25 nm. Then, under the conditions of the model experiment the effect of CdO in macro and nanosized particles on absorption, transformation, and structural and functional changes occurring in cells and tissues of Hordeum vulgare L. (spring barley) during its ontogenesis was analyzed.

Application of X-ray based modern instrumental techniques to determine the heavy metals in soils, minerals and organic media.

To evaluate the environmental concerns associated with heavy metals (HMs) during their translocations in food chains, it is crucial to gather data on the types of HMs present in soils in order to ascertain their toxicity and potential to migrate. An overview of the findings from several physical techniques used to determine and identify the HMs, sediments, individual minerals, and organic components in contaminated agricultural and industrial soils, is provided in this review article. These studies cover a variety of X-ray-based analytical techniques, including most widely used ones like X-ray absorption near edge structure, extended X-ray absorption fine structure, X-ray diffraction, and less popular ones X-ray fluorescence, etc.

Speciation of macro- and nanoparticles of CrO in Hordeum vulgare L. and subsequent toxicity: A comparative study.

Chromium (Cr) is reported to be hazardous to environmental components and surrounding biota when levels exceed allowable thresholds. As Cr is extensively utilized in different industries, thereby comprehensively studied for its toxicity. Along with Cr, the applications of nano-Cr or chromium oxide nanoparticles (CrO-NPs) are also expanding; however, the literature is scarce or limited on their phytotoxicity.

The enhanced photocatalytic performance of SnS@MoS QDs with highly-efficient charge transfer and visible light utilization for selective reduction of mythlen-blue.

Molybdenum disulfide (MoS) has recently been considered as an effective material for potential photocatalytic applications; however, its photocatalytic activity was limited due to the low density of active sites. In this work, MoS Quantum dots (QDs) were synthesized via the ultrasonication technique to construct heterostructure with SnS nanosheets (SnS@MoS QDs) and the prepared materials were tested for photocatalytic applications for Methylene blue (MB). Pristine SnS and SnS@MoS QDs nanocomposite were analyzed by XRD, TEM, PL, and Uv-Vis.
