Solution-processed CdTe nanocrystals solar cells have attracted much attention due to their low cost, low material consumption, and potential for roll-to-roll production. Among all kinds of semiconductor materials, CdS exhibits the lowest lattice mismatch with CdTe, which permits high junction quality and high device performance. In this study, high quality CdS nanocrystals were prepared by a n...
Solution-based synthesis is a powerful approach for creating nano-structured materials. Although there have been significant recent successes in its application to fabricating nanomaterials, the general principles that control solution synthesis are not well understood. The purpose of this LDRD project was to develop the scientific principles required to design and build unique nanostructures i...
Abstract Production of a ZnO–rGO composite, using novel one-pot method consisting in continuously flowing argon into GO aqueous suspension heated at 80 °C, the presence galvanized iron steel scrap is presented. FTIR shows complete disappearance functional groups and only C=C band remained, indicating extensive reduction. Raman spectra indicated sp 2 character increase after reaction E 2h mode Z...
a r t i c l e i n f o The in-situ synthesis of Cu/ZnO crystalline nanofibers is presented. The composite nanofibers are formed through the calcination and reduction of as-electrospun fibers consisting of poly(vinyl pyrrolidone) as well as Cu and ZnO precursors. The crystal structure and morphology of the synthesized fibers were characterized using X-ray diffraction, scanning electron microscopy...
Organic dyes used in the food and textile industries are primary sources of environmental contamination due to their high toxicity nonbiodegradability. This paper describes synthesis cellulose nanocrystals/zinc oxide (CNC/ZnO) nanocomposite via sol-gel method. Various characterization techniques such as FTIR spectroscopy, UV-Vis FESEM-EDX analysis were done. analyses initially confirmed formati...
