In this work we report the synthesis and characterization of hybrid nanostructures of multiwall carbon nanotubes (MWCNT) and cadmium sulphide (CdS) nanoparticles. In a solution of thioacetamide and cadmium sulphide, purified MWCNT are added to prepare the CNT/CdS hetrostructure. XRD diagrams, SEM images, and also photoluminescence spectra of the prepared samples are analyzed. SEM images show th...

A key feature of the 2007 financial crisis is that for some classes of securities trade has practically ceased. And where trade has occurred, it appears that market prices are well below their intrinsic values. This seems especially true for those securities where the payoff streams are particularly complex, for example, structured finance ABS CDOs. One explanation for this is that information ...

[email protected] Abstract – The CdO thin films were deposited using NaOH as the complexing agent by Successive Ionic Layer Adsorption and Reaction (SILAR) method. The UV-VIS-NIR spectroscopy was used for film characterization. The deposited CdO thin film shows high absorbance in the UV region and low in the visible to near IR region of the spectroscopy. The energy band gap of the deposi...

Cadmium oxide (CdO) thin films have been deposited by a locally developed spray pyrolysis method onto glass substrate at 473K. The optical and electrical properties of the as-deposited and annealed films are studied in details. The surface morphology of the samples was studied by scanning electron microscopy (SEM). The SEM micrograph of as-deposited film shows uniform deposition over the substr...

February 2000 www.dcrco.com n recent years, collateralized debt obligations (CDOs) have emerged as one of the largest and fastest growing sectors of the asset-backed securities (ABS) market. Due to increasing use of bond and loan collateral within one transaction, the term collateralized debt obligation is becoming more popular, and the terms collateralized bond obligation (CBO) and collaterali...

Template synthesis is a powerful method for the preparation of nanoscale materials with specific size and shape. Cadmium oxide (CdO) nanoparticles were synthesized by using sodium dodecyl sulfate (SDS), Cd(OAc)2.2H2O and sodium hydroxide as starting materials. The sample was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). The XRD pattern prove...

In this work, the optical emission spectrum technique was used to analyze of (CdO: Fe) plasma produced by laser Nd: YAG with a wavelength (532) nm, period 10 ns, and focal length cm in energy range (200-500) mJ. The electron temperature (Te) determined using method line intensities ratio. Using Saha-Boltzmann equation, density (ne) determined. Other parameters such as frequency (fp), Debye (λD)...

In this contribution, we report the synthesis of CdS nanoparticles directly conjugated to an enzyme, R-chymotrypsin (CHT) by chemical reduction in aqueous solution. Matrix-assisted laser desorption ionization (MALDI) mass spectrometry confirms the strong conjugation of CdS nanoparticles to CHT through covalent bonding in the CdS-CHT conjugates. High-resolution transmission electron microscopy (...

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...
