Abstract Bio-based cyclodextrins (CDs) are a common research object in supramolecular chemistry. The special cavity structure of CDs can form supramolecular self-assemblies such as vesicles and microcrystals through weak interaction with guest molecules. The different forms of supramolecular self-assemblies can be transformed into each other under certain conditions. The regulation of supramolecular self-assembly is not only helpful to understand the self-assembly principle, but also beneficial to its application. In the present study, the self-assembly behavior of epoxy-β-cyclodextrin (EP-β-CD) and mixed anionic and cationic surfactant system (sodium dodecyl sulfate/dodecyltrimethylammonium bromide, SDS/DTAB) in aqueous solution was studied. Morphological… More > Graphic Abstract

Abstract In the present investigation ZnO thin films have been prepared by sol-gel spin coating technique with different pH values. The effect of pH values of precursor solution on the crystal structural, morphological and humidity sensing properties of ZnO nanostructures have been investigated using different characterization technique. The crystal structure and phase analysis has been examined by powder X-ray diffraction (PXRD) technique. The PXRD pattern clearly revealed the ZnO thin films have hexagonal wurtzite crystal structure. The average crystallite size of ZnO thin films have been calculated using Scherer formula and found to be ~24 nm… More >

Abstract Silver selenide telluride Semiconducting (Ag₂Se_0.8Te_0.2) thin films were by thermal evaporation at RT with thickness350 nm at annealing temperatures (300, 348, 398, and 448) °K for 1 hour on glass substrates .using X-ray diffraction, the structural characteristics were calculated as a function of annealing temperatures with no preferential orientation along any plane. Atomic force microscopy (AFM) and X-ray techniques are used to analyze the Ag₂SeTe thin films' physical makeup and properties. AFM techniques were used to analyze the surface morphology of the Ag₂SeTe films, and the results showed that the values for average diameter, surface roughness, and More >

Abstract Manganese-doped cadmium sulphide semiconductor nanoparticles (CdS: Mn) NPs have been created utilizing a microwave-assisted solvothermal technique at different Mn concentrations (0, 1%, 3%, and 5%). The chemicals utilized for the preparation of Mn doped CdS nanoparticles were sodium sulphide (Na₂S.xH₂O), manganese chloride (MnCl₂.4H₂O), and cadmium acetate (CH₃COO)₂Cd., H₂O). To determine the structural dimensions of the generated nanoparticles, the Debye-Scherer equation was used to calculate the average crystallite size at the full-width half maximum (FWHM) of the diffraction peaks. FTIR spectra analysis was used to look at the various functional and vibrational groups present in the Mn-doped CdS More >

Abstract CdZnS thin films created via chemical bath deposition were examined to see how Cu doping affected their characteristics. Cu ions were added to the films in order to change their optical, structural, and morphological characteristics. These findings suggest that Cu doping can be used to modify the optical characteristics of CdZnS thin films. By using Xray diffraction (XRD) and the energy dispersive analysis of X-ray method (EDAX), we were able to investigate the compositional ratio as well as the structural features of the films. The field emission scanning electron microscopy (FESEM) technique was utilized in More >

Abstract Novel nanocomposite structure has been made from physical mixing of polymer blend consist PMMA, PEO and PS filled with selenium nanoparticles. The nanocomposite had been deposited on glass slide by drop casting to form a thin film. This film was examined by required instrument like FESEM, XRD, EDS and UV-Vis to show the main physical properties of it. The XRD results were reflected the crystallinity nature of selenium NPs. SEM result shows the porosity nature of prepared film , where the pore size ranging from nano to micro size on all the surface of film. More >

Abstract The objective of this study was to investigate the effects of root cutting stress on the dynamic changes of endogenous hormone content and growth characteristics of Quercus variabilis roots, and to explore the physiological role of endogenous hormones in regulating root-crown interactions in the short term. The morphological characteristics and endogenous hormone contents of normal roots (no root cutting, CK) and cut roots (cut by 1/3 of the length of the main root, RP) were determined by liquid chromatography, which was combined with mass spectrometry at different levels of different developmental stages. The results showed that… More >

Abstract Gas transport through nanochannels is ubiquitous in nature and also plays an important role in industry. The gas flow in this regime can be described by the Knudsen theory, which assumes that molecules diffusely reflect on the confining walls [1]. However, with the emergence of low dimensional carbon-based materials such as graphene and carbon nanotubes, it has been evidenced that this assumption might not hold for some atomically smooth surfaces, resulting in an anomalous enhancement of gas flux [2]. Moreover, in Knudsen theory, gas molecules are usually treated as mass points and distinguished solely by… More >

Abstract Food waste is recognized as a valuable source for potential agricultural applications to supply organic matter and nutrients to arable soil. However, the information on the combined application of food waste and the plant growth-promoting bacterial strain, Chlorella, related to plant metabolic features and sodium chloride content in arable soil is limited. The present study was conducted to investigate the exogenous application of food waste along with Chlorella, which improved the physio-morphological features of red pepper. Our results revealed that this combination enhanced the organic matter in the soil, ultimately improving the fertility rate of the More >
