We are currently developing 2D dosimeters with optical readout based on CdS or CdS/CdSe core-shell quantum-dots using commercially available materials. In order to understand the limitations on the measurement of a 2D radiation profile the 3D deposited energy profile of MeV energy electrons in CdS quantum-dot-doped silica glass have been studied by Monte Carlo simulation using the CASINO and PE...

The study was carried out to determine the effect of seasonal changes and oestrous cycle phase on serum progesterone (P4) and thyroxine (T4) profiles in Savanna Brown (SB) goats. Ten (n = 10) cycling SB goats with mean body weight and body mass index of 20.17 ± 0.2 kg and 6.2 ± 0.4, respectively were allotted to 2 groups of 5 animals each per season of study (Hot-rainy, HRS and cold-dry, CDR). ...

Well-defined CdS nanograin-sensitized one-dimensional (1D) Zr:α-Fe2O3 nanostructured arrays with enhanced photoelectrochemical performance are synthesized directly on F-doped SnO2 (FTO) using the hydrothermal method. Owing predominantly to the appropriate photogenerated electron-hole separation and charge collection in 1D Zr:α-Fe2O3 nanorods, hydrothermally deposited CdS/1D Zr:α-Fe2O3 samples e...

Large document repositories need to be organized, summarized and labeled in order to be used effectively. Previous clustering studies focused on organizing, and paid little attention to producing cluster labels. Without informative labels, users need to browse many documents to get a sense of what the clusters contain. Human labeling of clusters is not viable when clustering is performed on dem...

The preparation of fluorescent nanocomposite materials with tunable emission wavelengths by combining cellulose nanofibrils (CNFs) with inorganic nanoparticles is important for promoting CNFs applications. A CNF/CdS nanocomposite was prepared via in situ compositing at room temperature on oxidized CNFs with CdS quantum dots. By controlling the -COOH/Cd2+ ratio on the CNF, the feeding time of Na...

Wireless networks like mobile ad hoc networks are infrastructure-less networks and nodes in that network which communicate via radio propagation. In such networks, a Connected Dominating Set (CDS) can act as a virtual backbone, in order to make the routing efficient. A smaller virtual backbone incurs less communication overhead. Since computing a minimum CDS is NP-Complete, efficient approximat...

Semiconductor photocatalysis has been intensively studied in recent decades for a wide variety of application such as hydrogen production from water splitting and water and air treatment. The majority of photocatalysts are, however, wide band-gap semiconductors which are active only under UV irradiation. In order to effectively utilize visible solar radiation, this thesis investigates various t...

A review is presented on the use of charged cyclodextrins (CDs) as chiral selectors in capillary electrophoresis (CE) for the separation of analytes in pharmaceutical analysis. An overview is given of theoretical models that have been developed for a better prediction of the enantiomeric resolution and for a better understanding of the separation mechanism. Several types of charged CDs have bee...

Photoelectrochemical (PEC) water splitting is a promising route for solar energy harvesting and storage, but it has been highly limited by the performance of the semiconductor photoelectrodes. Herein, we report a small molecular amine-mediated solvothermal method for synthesizing CdS nanorods. The obtained CdS nanorods are hydrophilic and can be easily dispersed in water. Furthermore, the small...

A facile route to assemble cadmium sulfide (CdS) quantum dots (QDs) uniformly on the surface of titanate nanobelts (TNBs) through electrostatic interactions is demonstrated. The photophysical properties of the resulting TNB-CdS nanostructured composite, including optical limiting properties, were studied using ultraviolet-visible absorption spectroscopy, photoluminescence spectroscopy, and the ...
