this study was conducted to evaluate the long-term effects of in ovo injection of nano-silver, thyme and savory extracts in broiler breeder eggs on growth performance, lymphoid organ weights, immune and blood parameters and bone mineral concentration of broiler chicks. a total of 560 fertilized broiler breeder eggs were divided into 7 groups. on d 5 of incubation, eggs were treated with the fol...

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...

Spherical silver nanoparticles (nano-Ag) were synthesized and their antifungal effects on fungal pathogens of the skin were investigated. Nano-Ag showed potent activity against clinical isolates and ATCC strains of Trichophyton mentagrophytes and Candida species (IC80, 1-7 microg/ml). The activity of nano-Ag was comparable to that of amphotericin B, but superior to that of fluconazole (amphoter...

The application of the nano-sized materials continues to grow at a rapid rate in the fields of medicine, biotechnology, and environmental technology. Voltage-gated potassium currents play a key role in excitable cellular viability and function, especially in the central nervous system. The aim of this study was to investigate the actions of silver nano-particles (nano-Ag) on voltage-activated p...

The development of environmentally friendly materials has been the focus many research groups in recent years due to increased harmful effects plastics on environment. Bio-based are considered a key solution from sustainable manufacturing perspective. nano-coating biopolymer blends with silver nanoparticles is subject challenging projects line EU Directive environment protection and manufacturi...

The fabrication, characterization and application of nanostructured zinc oxide (ZnO) thin films on interdigitated silver electrodes were described for the determination of phosphate buffer saline (PBS) concentration. The ZnO thin films were synthesized on a silicon dioxide wafer using a sol-gel spin coating technique. Two different seed solutions were prepared by dissolving Zn-acetate dihydrate...

In this chapter, various synthesis routes for PZT powders and fabrication processing techniques for PZT ceramics and films are reviewed. Emphasis is placed on chemical routes, especially the hydrothermal synthesis of PZT powders. The principles of the colloidal chemistry in ceramic suspension and its application to the colloidal processing of ceramics and films, especially when using sub-micron...

Silver (Ag) is one of the seven metals of antiquity and an important engineering material in the electronic, medical, and chemical industries because of its unique noble and catalytic properties. Ag thin films are extensively used in modern electronics primarily because of their oxidation-resistance. Here we report a novel phenomenon of Ag nano-volcanic eruption that is caused by interactions b...

Nano-crystalline Si films with high conductivities are highly desired in order to develop the new generation of nano-devices. Here, we first demonstrate that the grain boundaries played an important role in the carrier transport process in un-doped nano-crystalline Si films as revealed by the temperature-dependent Hall measurements. The potential barrier height can be well estimated from the ex...

the aim study antibacterial effects of silver nanoparticles against resistant strains of e.coli bacteria.12 strains of e. coli strains arising urinary infection were isolated from hospitalized patient in zabolhospitals. minimum inhibitory concentration of winter cherry were determined by dilution method in various concentration on bacteria. the highest mic values was found to be 100ppm against ...
