BACKGROUND Antibiotic resistant bacteria can be considered as a main problem in infection management. Zinc oxide nanoparticles (ZnO NPs), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. METHODS In this study, Zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...

BACKGROUND The mechanisms governing the correlation between exposure to ultrafine particles and the increased incidence of cardiovascular disease remain unknown. Ultrafine particles appear to cross the pulmonary epithelial barrier into the bloodstream, raising the possibility of direct contact with the vascular endothelium. OBJECTIVES Because endothelial inflammation is critical for the devel...

The use of nanomaterial as a finishing agent in the textile industry continues to be developed. Nanoparticle zinc oxide (ZnONP) has anti-UV properties so that it can used protect color fabric from fading. Constraints using functionalization on are process application and also its poor adhesion. This research aims optimize ZnONP coating cotton-indigo maximized adsorbed with good durability. Opti...

Nanotechnology is an emerging technology for the treatment of waste water. Nanoparticles have its own advantages as higher surface area to volume ratio compared bulk material. In this study, zinc oxide-based nanoparticles were synthesized. Synthesized are characterized by UV-visible spectroscopy, Fourier transform infrared scanning electron microscopy, and energy dispersive X-ray spectroscopy (...

background: galvanization is the process of coating steel or cast iron pieces with a thin layer of zinc allowing protection against corrosion. one of the important hazards in this industry is exposure to zinc compounds specially zinc oxide fumes and dusts. in this study we evaluated chronic effects of zinc oxide on the respiratory tract of galvanizers. method : 188 workers were selected from a ...

the improvement of the physical properties of indium tin oxide (ito) layers is quite advantageous in photovoltaic applications. in this study the ito film is deposited by rf sputtering onto p-type crystalline silicon (c-si) with (100) orientation, multicrystalline silicon (mc-si), and glass substrates coated with zno and annealed in vacuum furnace at 400°c. electrical, optical, structural and m...

We study n-i-p amorphous silicon solar cells with light-scattering nanoparticles in the back reflector. In one configuration, the particles are fully embedded in the zinc oxide buffer layer; In a second configuration, the particles are placed between the buffer layer and the flat back electrode. We use stencil lithography to produce the same periodic arrangement of the particles and we use the ...

BACKGROUND Zinc oxide nanoparticle (ZNP) has been applied in various biomedical fields. Here, we investigated the usage of ZNP as an antigen carrier for vaccine development by combining a high affinity peptide to ZNP. RESULTS A novel zinc oxide-binding peptide (ZBP), FPYPGGDA, with high affinity to ZNP (K a  = 2.26 × 106 M-1) was isolated from a random peptide library and fused with a bacteri...

optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of zno semiconductor. in optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the bruggeman homogenization formalism. zno nano rods (zonrs) as a nucleus layer were fabricated on the indium tin oxide (ito) by chronoamperometry (ca) in a...
