The effect of additions of two series of SnO2 nanoparticles synthesized using two different methods on crystal structure and superconductivity of Bi1.6Pb0.4Sr2Ca2Cu3O10+δ (BPSCCO) superconductors was investigated. Two series of spherical SnO2 nanoparticles were synthesized independently by using ultra-sonication (US-SnO2) and hydrothermal (HT-SnO2) methods.

In this work, we have shown that the addition of Zn to nanocrystalline nickel ferrite enhanced its H2 sensing properties, such as sensitivity, response time, and stability. This is explained due to the formation of defects and oxygen vacancies in the crystal structure due to the substitution of Zn ions in place of Ni ions. These defects generated more active sites for H2 gas to interact with, resulting in improved sensing performance.

In this work, Al-doped ZnO and Fe-doped ZnO nanoparticles have been synthesized through the coprecipitationannealing method to create new and safer UV filters for sunscreen. The effects of metal doping on phase composition, crystal structure, surface morphology, specific surface area, and elemental composition were characterized by X-ray diffraction, Raman spectroscopy, field emission electron scanning microscopy, nitrogen adsorption-desorption experiments and energy-dispersive X-ray spectroscopy, respectively.

In this study, the gold nanoparticles (AuNPs) were synthesized via redox reaction, by using ethylene diamine tetra-acetic acid (EDTA) as a protecting and reducing agent, with tetrachloroauric acid (HAuCl4) as precursor and seed solution. The ultraviolet-visible spectroscopy (UV-Vis) method was utilized to investigated the reaction conditions (the EDTA:HAuCl4 ratio, the amount of seed solution and stirring solution time) at room temperature. The synthesized AuNPs were deposited on the surface of fluorine doped tin oxide (FTO) by electrophoresis deposition.

Carbon nanoparticles (CNPs) have received great attention because of their unique optical and electronic properties. To modulate their photoluminescence properties, nitrogen doping has been previously reported, but it was difficult to find correlations between the photoluminescence properties and the nanoparticle structure.

We theoretically study the plasmonic properties of graphene on bulk substrates and graphene-coated nanoparticles. The surface plasmons of such systems are strongly dependent on bandgap and Fermi level of graphene that can be tunable by applying external fields or doping. An increase of bandgap prohibits the surface plasmon resonance for GHz and THz frequency regime.

The as fabricated In-doped ZnO sensors showed enhanced sensitivity to CO gas with respect to pure ZnO one. Sensors with low dopant loading (1 at.% and 2 at.% In) were found to be more sensitive with shorter response and recovery times than those with high dopant loading.

The magnetization of the samples decreases as the doping concentration increases. I-V characteristics and complex impedance spectra at room temperature of samples were measured. The results show that the resistivity value of the doped samples decreases in the range of 5-6 orders in magnitude compared with that of the pure YIG sample.

Random lasers based on dye-doped silica nanoparticles are attracted for biomedical applications due to their biocompatibility and high brightness. Several laser structures including silica powder and film have been reported. However, the dependence of lasing characteristics including lasing threshold and emission wavelength on the laser size and working environment have not been explored.
