In the current study, biodegradable PHBV/PLGA blend nanoparticles (NPs) containing Teriparatide were loaded in hyaluronic acid/jeffamine (HA-JEF ED-600) hydrogel to prepare a combination delivery system (CDS) for prolonged delivery of Teriparatide. The principal purpose of the present study was to formulate an effective and prolonged Teriparatide delivery system in order to reduce the frequency...

Monodispersive carbon spheres with a high percentage of purity have been synthesized using a mixed-valent oxide-catalytic carbonization (MVOCC) process. In this paper, the chemical activities of the carbon spheres are examined by dispersing Pt, CdS and WO, nanoparticles, respectively, on the carbon surfaces from the microstructure information provided by transmission electron microscopy. The sp...

This paper reports the synthesis and characterization of photocatalyst CdS nanoparticles for investigation of photocatalytic degradation of 2,4,6-trichlorophenol. CdS nanoparticles were synthesized by the microwave-assisted sol-gel method and characterized by various techniques such as X-ray diffraction, filed emission scanning electron microscopy, energy dispersive spectroscopy, Fourier transf...

Dielectric properties of ionic composites consisted of cadmium octanoate matrix and semiconductor or metal nanoparticles have been investigated. The nanoparticles of different nature (semiconductor CdS, metal Au, and metal core-semiconductor shell Au-CdS) were chemically synthesized in the smectic A phase of (Cd(+2)(C7H15COO)(-2), CdC8) that was used as a nanoreactor. These nanocomposites are v...

Semiconductor photocatalysis holds promising keys to address various energy and environmental challenges. Most studies to date are based on ensemble analysis, which may mask critical photocatalytic kinetics in single nanocatalysts. Here we report a study of imaging photocatalytic hydrogen production of single CdS nanoparticles with a plasmonic microscopy in an in operando manner. Surprisingly, ...

Sowing the seeds: the growth of Au and Ag(2)S nanoparticles at distinct positions on CdSe-seeded CdS heterostructured nanorods can be precisely controlled by variations in the concentration of the Au and Ag precursors, respectively. The ability to direct growth on the nanorods can lead to "Janus-type" structures where Au is located at the more reactive end of the nanorod, whilst Ag(2)S is locat...

The formation of cadmium sulfide (CdS) particles in the gaps between the layers of the multilamellar vesicles is described, introducing a new pathway in the preparation of nanometer-scale particles. The in situ structural characterization of both the CdS particles and the vesicles as a reaction medium was performed in the early and final states of the process by using anomalous small-angle X-ra...

Oxidized macroporous silicon structures with CdS surface nanocrystals have been proposed to enhance the photoluminescence of CdS nanoparticles due to reducing the electron recombination outside the nanoparticle layer. It has been found that the resonance electron scattering on the Si–SiO2 interface for samples with low concentration of Si–O–Si states transforms into scattering on ionized surfac...

Surfactant based aqueous foams provide a very efficient and simple chemical route for the synthesis of various nanomaterials with controllable structure, size and shape. In this present work, a one-step process for the synthesis of morphologically controlled CdS nanoclusters has been described. Aqueous soluble CdCl2 and the surfactant AOT are homogeneously mixed together to produce a stable aqu...
