Bimetallic nanoparticles of silver (Ag) and gold (Au) were synthesized at room temperature using Curcumin. Reduction process of silver and gold ions with different molar ratios leads to production of different nanostructures including alloys and core-shells. Produced nanoparticles were characterized simultaneously with FTIR, UV/vis. spectroscopy, transmission electron microscopy (TEM), and Energy-dispersive X-ray (EDAX). UV/vis. optical absorption spectra of as synthesized nanoparticles reveals presence of surface palsmon resonance (SPR) of both silver at (425 nm) and gold at (540 nm) with small shift and broadness of gold band after mixing with resucing and capping agent in natural extract which suggest presence of bimetallic nano structure (Au/Ag). FTIR and EDAX data approve the presence of bimetallic nano structure combined with curcumin extract. TEM micrographs shows that silver and gold can be synthesized separately in the form of nano particles using curcumin extract. Synthesis of gold nano particles in presence of silver effectively enhance and control formation of bi-metallic structure.

Today, one of the most popular nanomaterials are thin nanofibrous layers, which are used in many fields of industry, eg electronics, optics, filtration and the textile industry. They can be produced by various methods, such as drawing, template synthesis, molecular self-assembly or phase separation method, but the most common method is electrospinning from a solution or melts. Electrospinning is gaining more and more interest due to its versatility, simplicity and economy as well as the possibility of producing fibers from various types of polymeric, ceramic and metalic materials. Nanofibrous layers produced by this method are characterized by high quality and the desired physicochemical properties.

Dielectric studies on water dynamics in aqueous solutions of amphiphilic random copolymers confirm the self-assembly into globular like core–shell single-chain nano-particles (SCNPs) at concentrations well above the overlap concentration.

The effect of NiO contents on the microstructure of mesoporous NiO - Gd 0.25 Ce 0.75 O 2-x ( NiO -GDC) composite for intermediate temperature solid oxide fuel cells (IT-SOFC) was investigated. Mesoporous NiO -GDC powders with different NiO contents were synthesized by self-assembly hydrothermal method using tri-block copolymer, Pluronic F127, as a structure directing agent. Grain growth/agglomeration behaviors of NiO particles and changes of mesoporous structure of GDC particles were characterized by microstructural analyses. NiO -GDC powders were composed of GDC nano particles with ordered mesopore inside the particles and octahedral NiO grains with truncated-edges. As the amount of NiO increases, specific area value of mesoporous NiO -GDC was decreased, and the agglomeration/growth behavior of NiO grains was accelerated.
