We review the crystal structures, electrospray ionization mass spectra (ESI-MS) data and chiral HPLC data for the racemic and optically pure mononuclear AuL2 complexes, and for racemic [AuLI]n and optically pure [AgLII]n polymers (LI = thiomalate, LII = D-penicillamine). We postulate an equilibrium between polymeric, mononuclear and free ligand species for [AuLII]n (gold sodium thiomalate or GS...

Abstract We introduce metal nanovoid (NV) and on nano-hemisphere (MoNH) structures to tune the localized surface plasmon resonance (LSPR) for wider wavelength ranges. The NV were constructed with layers gallium oxide nano hemisphere (NH) structures, MoNH dielectric random silver NH structures. These fabricated via thermal annealing of deposited thin films without top-down nanofabrication techno...

thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...

tensile strength. Moreover, making wool fabrics antibacterial is a considerable task for protection of fabrics and consumers against microbial attack and growth. In this research nano-silver was synthesized using reduction of silver nitrate by sodium bisulfite along with increasing the fiber fineness using tensile. This process was successfully introduced Iranian coarse wool yarns with loading ...

There are two mass diffusion processes regarding the vapor-liquid-solid (VLS) growth of nanostructures: one is inside the catalyst droplet toward the liquid-solid interface; the other is along the side surface planes of the growing nanostructures. In this letter, microscale, modulated mass diffusion scenarios are exhibited through the synthesis of two types of ZnS nanostructures in an Au-cataly...

Objective(s): The enzymatic activity of fungi has recently inspired the scientists with re-explore the fungi as potential biofactories rather than the causing agents of humans and plants infections. In very recent years, fungi are considered as worthy, applicable and available candidates for synthesis of smaller gold, silver and other nano-sized particles.  Materials and Methods: A standard str...
