“…In comparison, the PL intensity of 50 : 2 CN-PDPB composites is lower than that of g-C 3 N 4 due to the easy transfer of carriers between g-C 3 N 4 and PDPB, indicating the increase in the separation efficiency of photo-generated electron-hole pairs. [40][41][42] Besides the photoluminescence measurement, electrochemical impedance spectroscopy (EIS) is also applied to investigate the charge transfer resistance of the catalysts. [43][44][45] The EIS results of prepared samples are presented in Fig.…”

AgNPs have attracted considerable attention in many applications including industrial use, and their antibacterial properties have been widely investigated. Due to the green synthesis process employed, the nanoparticle surface can be coated with molecules with biologically important characteristics. It has been reported that increased use of nanoparticles elevates the risk of their release into the environment. However, little is known about the behaviour of AgNPs in the eco-environment. In this study, the effect of green synthesized AgNPs on germinated plants of maize was examined. The effects on germination, basic growth and physiological parameters of the plants were monitored. Moreover, the effect of AgNPs was compared with that of Ag(I) ions in the form of AgNO3 solution. It was found that the growth inhibition of the above-ground parts of plants was about 40%, and AgNPs exhibited a significant effect on photosynthetic pigments. Significant differences in the following parameters were observed: weights of the caryopses and fresh weight (FW) of primary roots after 96 h of exposure to Ag(I) ions and AgNPs compared to the control and between Ag compounds. In addition, the coefficient of velocity of germination (CVG) between the control and the AgNPs varied and that between the Ag(I) ions and AgNPs was also different. Phytotoxicity was proved in the following sequence: control < AgNPs < Ag(I) ions.

“…Introduction: One-dimensional semiconductor nanostructures, such as nanowires, nanospheres, and nanotubes have attracted considerable attention in the field of optoelectronic nanodevices and catalysis in the last decade, due to their excellent optical and electrical properties [1]. ZnSe, as one of the most important group II-VI compounds materials, is regarded as a promising material in the fabrication of light-emitting diodes, solar cell and photodetectors because of its wide band gap (2.7 eV, at room temperature) and high exciton binding energy (21 meV) [2][3][4][5]. Subsequently, various one-dimensional ZnSe nanostructures are synthesised gradually via different methods, such as metal organic chemical vapour deposition, solvothermal method, thermal evaporation and laserassisted catalytic growth [6][7][8][9].…”

In this work, grass-like, needle-like and chrysanthemum-like ZnSe nanostructures have been prepared by hydrothermal method at 200°C for 24 h successfully. With different amounts of diethanolamine, various morphologies of ZnSe formed. The structures, morphologies and crystal orientation of as-synthesised ZnSe nanostructures were characterised by X-ray diffractometer (XRD) and scanning electron microscope. The experiment result of XRD indicated that the structures of all as-synthesised ZnSe nanomaterials were cubic crystal. The field emission (FE) properties of as-synthesised samples were tested and the results revealed that the FE properties were influenced by the morphologies significantly. The FE measurement showed that the chrysanthemum-like ZnSe nanostructures had the best FE properties with a high field enhancement factor of 4328 and a low turn-on electric field of 3.4 V μm −1 among all the as-synthesised ZnSe nanostructures. The reaction mechanism of various morphologies ZnSe was also explained as follow.
