The main goal of this work was to synthesize CdSe/CdS (core-shell) nanoparticles stabilized by polymer ligand using entirely aqueous colloidal chemistry at room temperature. First, the CdSe core was prepared using precursors and acid-functionalized poly(vinyl alcohol) as the capping ligand. Next, a CdS shell was grown onto the CdSe core via the layer-by-layer technique. The CdS shell was formed...

The desired control of particle size, doping element composition, and surface structure of carbon dots (CDs) are vital for understanding the fluorescence mechanism and exploring their potential applications. Herein, nitrogen-doped CDs (N-doped CDs) have been synthesized with tartaric acid and various alkylol amines (monoethanolamine, biethanolamine and triethanolamine) under microwave irradiati...

The introduction of credit default swaps (CDS) trading on an underlying firm may influence its future access to external financing and, hence, its precautionary demand for cash. In this paper, we empirically estimate this effect of CDS trading, using a comprehensive sample of North American corporate CDS introductions between 1997 and 2009. We show that corporate cash holdings, as a proportion ...

OBJECTIVES To investigate the association between satisfaction with conventional complete denture prostheses (CDs), impacts of CDs on daily living and personality profiles. MATERIALS AND METHODS Fifty-six patients (28 males and 28 females; mean age 53.79 ± 7.762 years) with fitted upper and lower removable CDs were recruited for this study. Clinical success of CDs was assessed according to sp...

BACKGROUND Computerized clinical decision support (CDS) can help hospitals to improve healthcare. However, CDS can be problematic. The purpose of this study was to discover how the views of clinical stakeholders, CDS content vendors, and EHR vendors are alike or different with respect to challenges in the development, management, and use of CDS. METHODS We conducted ethnographic fieldwork usi...

This paper reports cadmium sulphide nanoparticles-(CdS NPs)-graphene nanocomposite (CdS-Graphene), prepared by a simple method, in which CdS NPs were anchored/decorated successfully onto graphene sheets. The as-synthesized nanocomposite was characterized using standard characterization techniques. A combination of CdS NPs with the optimal amount of two-dimensional graphene sheets had a profound...

PURPOSE To determine the extent to which behavioral and physiological responses during child-directed speech (CDS) correlate concurrently and predictively with communication skills in young children with autism spectrum disorders (ASD). METHOD Twenty-two boys with ASD (initial mean age: 35 months) participated in a longitudinal study. At entry, behavioral (i.e., percentage looking) and physio...

Concerns have been raised, especially since the global financial crisis, about whether trading in credit default swaps (CDS) increases the credit risk of the reference entities. This study examines this issue by quantifying the impact of CDS trading on the credit risk of firms. We use a unique, comprehensive sample covering 901 CDS introductions on North American corporate issuers between June ...
