ardekoul fault zone which is along nnw-sse is located in eastern iran and northern part of the sistan subzone. dextral strike-slip fault zone of ardekuol is made of six main segments including korizan (28 km), bohn abad (8.8 km), abiz (32 km), gazkoon (20 km), moein abad (30.4 km), ghal maran (12 km), and two minor segments including olang morgh (12.8 km) and seh pestan (9.6 km).  the studied r...

background: saffron, the dried stigmas of crocus sativus, is the world's most expensive spice which has been used as food additive and flavoring agent. the aim of the present study has been to investigate the combination effects of gamma irradiation and silver nano particles packing on the chemical properties of saffron during storage time. a combination of hurdles can ensure stability and...

OBJECTIVES The aim of this study was to investigate the effects of nano-silver and garlic administration during pregnancy on neuron apoptosis in rat offspring hippocampus. MATERIALS AND METHODS FIFTY PREGNANT WISTAR RATS WERE RANDOMLY DIVIDED INTO FIVE GROUPS: 1- nano-silver (N.S) group; 30 mg/kg of N.S treated via gavage. 2- Control (C) group, administrated with distilled water via gavage. 3...

BACKGROUND There is an increasing commercial demand for nanoparticles due to their wide applicability in various markets, including medicine, catalysis, electronics, chemistry, and energy. In this report, a simple and ecofriendly chemical reaction for the synthesis of gold and silver nanoparticles from Trianthema decandra (Aizoaceae) has been developed. METHODS AND RESULTS On treatment of aqu...

We prepared rod-shaped gold nanorattles solid gold nanorods surrounded by a thin gold shell using a galvanic replacement process starting with silver-coated gold nanorods. These structures are very promising candidates for catalytic applications and optimized plasmon sensors. They combine the advantages of rods (low plasmon resonance frequency, large polarizability, small damping) with the high...

Abstract The processes of laser dispersion materials for high-performance generation colloidal nanoparticles in liquids have been considered. Various and material parameters affecting this process studied. Efficiencies ergonomics the with help systems having nano-, pico-, femtosecond pulse durations compared using optical mass criteria by example ablation a chemically inert model (gold) distill...

introduction in this study, we describe the results of controlled synthesis and application of gold coated fe3o4/sio2 nano-shells combined with the optical property of gold for enhancement of selective photothermal interaction with cancerous cells based on the surface plasmon resonance (spr) phenomena. materials and methods magnetite nano-particles (mnps) were prepared by means of co-precipitat...

In the emerging issue of increased multi-resistant properties in foodborne pathogens, silver nano particles are being used increasingly as antimicrobial agents. Thus, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of Nano Colloidal Silver towards food-borne pathogens such as Escherichia coli O157:H7, Listeria monocytogenes, Salmonella enterica Serovar Ty...

Abstract The effects of engineered nanoparticles (ENPs) in living organisms are described in a myriad of articles. Most of the literature on this topic is devoted to plants of different gender and species. Studies from laboratories and greenhouse facilities highlight effects on chlorophyll production, plant growth, stress enzyme activities, phytotoxicity, cytotoxicity, and genotoxicity. With fe...
