In this work In2S3 and CdS nanoparticles were prepared by a simple hydrothermal method and then annealed at 500 °C for 2 h in an Ar gas until CdIn2S4(CdIS)-CdS nanocomposites were formed. Afterwards, efficiency of the as-synthesized CdIS-CdS nanocomposite in quantum dot-sensitized solar cells (QDSSCs) was evaluated. For this purpose, the as-prepared CdIS-CdS nanocomposites were deposited on TiO...

BACKGROUND There is a high prevalence of depression in patients with heart failure (HF) that is associated with worsening prognosis. The value of using a reliable and valid instrument to measure depression in this population is therefore essential. We validated the Cardiac Depression Scale (CDS) in heart failure patients using a model of ordinal unidimensional measurement known as Mokken scalin...

Cyclodextrins (CDs) are cyclic oligosaccharides formed by R(1f4) linked D-glucose units.1,2 They are named R-, â-, and γ-CD depending on the number of glucose units in the macrocycle (six, seven, or eight, respectively). CDs are one of the most widely used systems in supramolecular chemistry,3 since they include a large variety of organic compounds inside their hydrophobic, torusshaped cavity. ...

The process of doping of CdS nanoparticles with Mn during colloidal synthesis is analyzed by EPR and optical studies. Analysis of EPR results demonstrated that Mn(2+) ions are successfully incorporated into the nanoparticles and occupy the crystal sites both in the bulk of a NP and near the surface of a NP. Optical absorption measurements revealed the retardation of absorption edge shift during...

Carbon dots (CDs) and graphitic carbon nitride (g-C3N4) composites (CD/g-C3N4) were successfully synthesized by a hydrothermal method using urea and sugarcane juice as starting materials. The chemical composition, morphological structure and optical properties of the composites and CDs were characterized using various spectroscopic techniques as well as transmission electron microscopy. X-ray p...

An inorganic layer and dye molecules have synergistically suppressed the recombination in a quantum dot sensitized solar cell (QDSSC), by the design of a structure featured TiO2-CdS-ZnS-N3 (N3: RuL2(NCS)2 (L = 2,2'-bipyridyl-4,4'-dicarboxylic acid)) hybrid photoanode. When fabricated into solar cells, a cobalt complex-based electrolyte rather than an iodine-based one was employed to obtain an i...

Fluorescent carbon-based materials have drawn increasing attention in recent years owing to exceptional advantages such as high optical absorptivity, chemical stability, biocompatibility, and low toxicity. These materials primarily include carbon dots (CDs), nanodiamonds, carbon nanotubes, fullerene, and fluorescent graphene. The superior properties of fluorescent carbon-based materials disting...

The financing issue is increasingly becoming a key problem for brownfield remediation in public land ownership, and Public Private Partnership (PPP) mode considered potentially effective solution. However, some barriers impede the utilization of PPP into projects situation ownership. By taking China as an example, study investigates when used to deal with dilemmas. Specifically, 39 original are...

Across the globe, critical infrastructures constantly face the risk of cyber and/or other attacks from hostile and malicious entities as well as damage inflicted by natural disasters. This paper seeks to identify the critical infrastructure sectors of a country, namely India, and to explore the dependencies existing among them. The research draws on the extant literature as well as expert opini...
