Mercuric iodide and bismuth tri-iodide nanoparticles were synthesized by suspension in octadecene, from Hg(NO3)2. H2O and I2, and from Bi(NO3)3. 5H2O and I2, respectively. The best synthesis conditions were 2 hrs. at 60-70 oC, followed by 10 min. at 95-110 oC for mercuric iodide nanoparticles, and 4 hrs. at 80-110 oC, followed by 10 min. at 180-210 oC for bismuth tri-iodide ones. Nanoparticles were...
Currently, consumer electronics, flexible and portable electronic products are the most popular because of further miniaturization accompanying more functionality per device and low costs. To produce high volume, high-density interconnect substrates, flexible printed circuits (FPCs) will become more and more important. For the fabrication of FPCs, polyimides (Pis) possess many outstanding properties,...
Hybrid nanocomposites based on crystalline nanoparticles dispersed in polymer matrix has been widely studied in the past few years because of the ability of these materials to combine both properties of organic polymer and inorganic nanoparticles. The aim of this work is to tune mechanical properties of piezoelectric polymer by adding nanoparticles to the matrix. In this paper alumina nanoparticles...
The NiCoFerrite nanoparticle has been prepared using thermal method. Polyvinyl pyrrolidon (PVP) was used as a reducing agent due to its reducing effect on agglomeration of particles. The characterization studies such as X-ray diffraction (XRD) and transmission electron microscopy (TEM) have been done for explore the particles size. By Scherer's equation the average particles size has been estimated...
Regularly faceted copper (Cu) particles ranging from tens of nanometers to submicron were obtained by annealing Cu-Zr films on polyimide and single Si (100) substrates. XRD, TEM, SEM and EDS were used to characterize their microstructural properties. The results show that these particles are pure Cu element and single crystals with [111] preferred orientation. Systematical analysis demonstrates that...
The flame-made (5/5) pure ZnO and WO3-doped ZnO nanoparticles containing 0.25, 0.50, and 0.75 mol% of WO3 were successfully synthesized by flame spray pyrolysis (FSP). These materials were studied for NO2, CO and H2 gas sensing at different gas concentrations and operating temperatures ranging from 300-400??C in dry air. The crystalline phase, morphology and size of the nanoparticles were characterized...
The CdSe nanoparticles have been synthesized by hot-injection method, and thermal annealing was used to improve the crystallinity of synthesized nanoparticles and reconstruct the surface of nanoparticles. The synthesized and annealed CdSe nanoparticles were characterized by TEM, XRD and PL spectra. After thermal annealing followed by a solvent exchange process, the CdSe nanoparticles were used to...
A novel optical biosensor with gold surface bound silver nanoparticles has been constructed for detection of bio-molecules like antigen, antibody protein and DNA plasmid, which exhibited distinct optical properties of localized surface plasmon resonance (LSPR). The silver colloidal nanoparticles were prepared by using sodium borohydride reduction of silver nitrate and characterized by using UV-vis...
