Metallothioneins are small cysteine-rich proteins coordinating various transition metal ions preferably with the electron configuration d(10). They are ubiquitously present in all phyla, and next to phytochelatins they represent a successful molecular concept for high-capacity metal ion binding. Recent studies showed the incorporation of sulfide ions into the metal-thiolate cluster of metalloth...

Nanohelices of cadmium sulfide (CdS) have been made by the mineralization of supramolecular organic ribbons. A schematic representation of how coiled CdS helices (yellow) can be templated from a twisted ribbon (blue) by growth along one face of the ribbon is shown top right.

Recent advances in nanotechnology could facilitate the production of cheaper solar cells. This review describes synthetic routes to various nanostructured materials that are potentially useful in photovoltaic applications. We have focused on materials that are based on earth abundant elements and/or those that are held to have lower toxicity. Methods to synthesize binary chalcogenides with vari...

Metal coated Hollow Glass Waveguides (HGWs) incorporating single dielectric thin films have been widely used for the low-loss transmission of infrared radiation in applications ranging from surgery to spectroscopy. While the incorporation of single dielectric film designs have traditionally been used in metal/dielectric coated HGWs, recent research has focused on the development of alternating ...

cadmium sulfide nanoparticles were grown using wet chemical method by dissolving the reactants ofcadmium acetate and sodium sulfide in the presence of thioglycerol (tg) as capping agent in ethanolsolvent. different nanoparticle sizes and size distribution were obtained through varying the molaritiesof thioglycerol. at higher tg concentration, synthesis provides a nearly monodisperse nanoparticl...

Semiconductor-metal hybrid nanostructures offer a highly controllable platform for light-induced charge separation, with direct relevance for their implementation in photocatalysis. Advances in the synthesis allow for control over the size, shape and morphology, providing tunability of the optical and electronic properties. A critical determining factor of the photocatalytic cycle is the metal ...

Cytotoxicity is a severe problem for cadmium sulfide nanoparticles (CSNPs) in biological systems. In this study, mercaptoacetic acid-coated CSNPs, typical semiconductor Q-dots, were synthesized in aqueous medium by the arrested precipitation method. Then, amino-terminated polyethylene glycol (PEG) was conjugated to the surface of CSNPs (PCSNPs) in order to introduce amino groups to the surface....

Cadmium sulfide and lead sulfide semiconducting nanoparticle chains have been fabricated for the first time by exploiting a general property of proteins, amyloidogenicity. The diameter of the CdS and PbS nanowires was tuned in the range of ∼50 to ∼350 nm by changing the process parameters. The nanoparticle chains were characterized by field emission scanning electron microscopy, UV-visible spec...

We report a hybrid approach for photonic systems that combines chemically synthesized single nanowire emitters with lithographically defined photonic crystal and racetrack microresonator structures. Finite-difference time-domain calculations were used to design nanowire photonic crystal structures where the photonic band gap overlaps the electronic band gap of the nanowire. Photoluminescence (P...
