“…1C). Our results revealed that the characteristics of calcium phosphate, copper oxide and silicon dioxide nanoparticles are similar with those previously reported (Caiab and Tang, 2008;Yuvakkumar et al, 2011;Suriyaprabha et al, 2014;Prachi et al, 2014) whot stated that nano-calcium had spherical shape between 25-100nm in diameter by using atomic force micrscopy (AFM) comfired by transmission electron silicon dioxide (TME) also silicon dioxide had spherical shape with dimater 20-40nm.…”

Black scurf disease caused by Rhizoctonia solani, was a serious and common disease on potato worldwide. Effect of nanoparticles forms of Tri-calcium phosphate, copper oxide and silicon dioxide nanoparticle was evaluated at five concentrations to control black scurf disease in vitro and in vivo. Examination of treated R. solani with different tested nanoparticle was done using Transmission Electron Microscope (TEM). Activities of defense related enzyme were determined in artificially inoculated potato plants and tubers (cv. Spunta) with R solani. Physical characteristics of tested nanoparticles exhibit that all of them are spherical in shape and varied in their sizes. Also, all tested nanoparticles exhibited inhibitory effect of R. solani. Non-copper oxide was the most effective one (56.42 %) in suppressing the mycelial growth of R. solani at concentration 250 µl/L. The TEM examination of treated R. solani with different nanoparticles exhibit that instability they caused in cell wall thickness, abnormalities of nucleus and disappearance of nuclear membrane. All tested nanoparticles reduced of incidence and severity% of black scurf disease at concentrations 150 and 200 µl/L. during 2014 and 2015 seasons. Results cleared also that treating potato plants with different tested nanoparticles affected positively the activities of poly phenoloxidase, peroxidase, catalase and chitinase enzymes in leaves and tubers.

The effect of silica nanoparticles and conventional silica sources on the changes in microbial biomass and silica availability to pure soil and maize rhizosphere was studied. Nanosilica (20-40 nm) was synthesized from rice husk and comprehensively characterized. The efficiency of nanosilica was evaluated in terms of its effects on beneficial microbial population such as phosphate solubilizers, nitrogen fixers, silicate solubilizers, microbial biomass carbon and nitrogen content, and silica content in comparison with other silica sources such as microsilica, sodium silicate, and silicic acid. Nanosilica significantly (P < 0.05) enhanced microbial populations, total biomass content (C = 1508 μg g(-1) and N = 178 μg g(-1) ), and silica content (14.75 mg mL(-1) ). Although microsilica sources enhanced factors associated with soil fertility, their use by maize roots and silicification in soil was found to be less. The results show that nanosilica plays a vital role in influencing soil nutrient content and microbial biota and, hence, may promote the growth of maize crop.

Magnetic and electrical properties of polypyrrole nanocomposites with iron nanoparticles attached to 2-acrylamido-2-methyl-1-propanesulfonic acid

Polypyrrole (PPy) nanocomposites with iron nanoparticles attached to 2-acrylamido-2-methyl-1-propanesulfonic acid (AMP) were chemically prepared by varying the concentration of AMP using ammonium persulfate as an oxidant. The synthesized composites were characterized by using Fourier transform infrared (FTIR) spectroscopy, and their surface morphology and amended crystallinity were determined by using the transmission electron microscopy (TEM) and X-ray diffraction (XRD), respectively. The electrical and magnetic properties of PPy-Fe-AMP composites were investigated at room temperature. The increase of AMP has brought out a significant increase of DC conductivity and magnetic saturation moment of the composites, which might have been caused by the increased mobility of charge carriers due to the hydrophilic AMP components.
