In this work we performed a detailed investigation of the photostability of bottom-up produced carbon nanodots (CDs) prepared from citric acid and urea by solvothermal synthesis. Analytical ultracentrifugation (AUC) reveals that the CDs have a hydrodynamic diameter of <1 nm and a very narrow size distribution. In the community it is widely assumed that CDs are photo-stable. In contrast, we foun...
Since several years the inclusion of organic compounds (guests) within the hydrophobic cavity (host) of cyclodextrins (CDs) has been the subject of many investigations. Interestingly, the formation of inclusion complexes could affect the properties of the guest molecules and, for example, the influence of the delivery system can be a method to improve/change the photochemical behavior of the gu...
CdS crystallites with rod- and flower-like architectures were synthesized using a facile hydrothermal growth method. The hexagonal crystal structure of CdS dominated the growth mechanisms of the rod- and flower-like crystallites under specific growth conditions, as indicated by structural analyses. The flower-like CdS crystallites had a higher crystal defect density and lower optical band gap v...
Background & Aim: Financing of the health system one is one of the four main functions of the health system. It is useful to use the capacity and resources of charities for this purpose. The purpose of this research is to identify and design the financing model of the health system based on the efforts of donors. Methods: This study is a mixed type of research. First the components were identi...
Whole-exome sequencing (WES) is a useful method to identify disease-causing mutations, however, often no candidate mutations are identified using commonly available targeted probe sets. In a recent analysis, we also could not find candidate mutations for 20.9% (9/43) of our pedigrees with congenital neurological disorder using pre-designed capture probes (SureSelect V4 or V5). One possible caus...
Abstract In this study, Mn doped CdS/ZnO nanocomposites synthesized by co-precipitation method and its photocatalytic activity was tested using methylene blue under solar light irradiation. The prepared hybrid are characterized different physicochemical techniques including XRD, FESEM, EDX, TEM, UV-vis DRS PL analysis. From the XRD analysis, ZnO/CdS nanocomposite diffraction peaks only reflect ...
The photoelectrochemical properties of nanoheterostructures based on the wide band gap oxide substrates (ZnO, TiO2, In2O3) and CdS nanoparticles deposited by the successive ionic layer adsorption and reaction (SILAR) method have been studied as a function of the CdS deposition cycle number (N). The incident photon-to-current conversion efficiency (IPCE) passes through a maximum with the increas...
The photocatalytic production of molecular hydrogen (H2) on ternary composites of Pt, CdS, and sodium trititanate nanotubes (NaxH2-xTi3O7, TNTs) is examined in an aqueous 2-propanol (IPA) solution (typically 5 vol%) at a circum-neutral pH under visible light (λ > 420 nm). The H2 production rates are dependent on the Pt-loading level, and the optimum production rate in the Pt/CdS/TNTs is approxi...
چکیده: در این رساله نانوذرات نیمرسانای cds با استفاده از روش های ترموشیمیایی و روش تابش امواج مایکروویو سنتز شده اند. نانوذرات سنتز شده آبدوست بوده و گسیل سفید رنگ در محدوده 400-750 nm را نشان دادند. این گسیل پهن به تله های سطحی cds مربوط می شود. نانوذرات سنتز شده برای ساخت قطعه نورگسیل با ساختار ito/pedot-pss/pvk/cds/al استفاده شدند. برای ساخت قطعه نورگسیل در مرحله اول لایه های pedot-pss و لا...
