In this study, silica nanoparticles immobilized on zeolite 13X granules (SZX13), by sol gel method was synthesized. The aim of this study was determination of the performance of prepared nano sorbent in nickel ions removal from aqueous solution. Material and Methodology:The present historical research, with an analytical-comparative approach, has used inferential and deductive reasoning. First, the principles of organic style architecture, derived from a comparative study of written evidence and existing documents, were explained as a criterion of measurement. Then, a list of works of organic architecture in Iran was prepared to select samples for analysis by purposive sampling. Finally, the analyzed samples were compared with the principles of organic architecture. Findings: Scanning Electron Microscope analysis showed that the immobilization process was successfully carried out and the immobilized particles has a nano size distribution. Optimized values for each factor to achieve the highest uptake were found to be as follows: The Ni initial concentration of 60 mg/L, the pH 6, the adsorbent (SZX13) dose of 1 g, at 40 ° C. Discussion and Conclusion: Results showed that the immobilization of nano particles on the zeolite not only led to that the particles were distributed in an expanded volume, but also prepare the accessible usage of that in an industrial scale. In addition, with immobilization of silica nanoparticles onto zeolite granules, the sorption of nickel ions were increased in comparison to that by using zeolite 13X, and the removal percentage was increased from %26 to %43.98.

The first factor was amino acid (Botamisol 45%) at two levels (application and non- application) and the second factor was iron fertilizer in five levels: without iron fertilizer (control), the soil application, the foliar application, the soil + foliar applications, the soil + foliar applications. The results of variance analysis showed that all of the attributes studied were affected by using both amino acid and iron containing fertilizer (nano and chelate) significantly at the 1% level of probability. Mean comparisons also showed that the attributes under study positively responded to amino acid applications. The soil and foliar applications of iron nano particles were higher effective. This indicates that application of iron nano particles were more effective on desired attributes than iron chelate application. Amino acid and iron fertilizer interactions indicated that traits like protein and iron percentage, average weight of tuber, biological yield and marketable yield responded quite positively to amino acid and nano-iron foliar and soil applications.

MoreIn order to evaluate the effect of water deficit stress and foliar application of zinc oxide nano particles on morphophysiological characteristics in Withania coagulans L. landraces, a factorial experiment in a completely randomized design with 3 replications was setup. The experiment included various irrigation regimes (control), (medium stress), (severe stress), four landraces (Fanuj, Khash, Saravan and Sarbaz), with and without foliar application of zinc oxide nano particles. The experiment was conducted in green house of the faculty of Agriculture, Tarbiat Modares University, during 2018-2019. The highest leaf area (538.92 cm2) was related to Sarbaz in control irrigation and the lowest leaf area (245.88 cm2) was related to Khash in severe water deficit stress. Based on the comparison results, the mean of maximum plant dry weight (1.76 g) was related to Sarbaz and control irrigation and the lowest plant dry weight (0.63 g) was related to Fanuj and severe water deficit stress. Also, the highest amount of chlorophyll a (2.55 μmol.g-1) was related to Khash, control irrigation and foliar application of zinc oxide nano particles. The highest amount of chlorophyll b (1.26 μmol.g-1) was related to Fanuj, control irrigation and foliar application of zinc oxide nano particles, which was not significantly different from other landraces. Also, the lowest amount of chlorophyll b (0.62 μmol.g-1) was related to Khash, severe water deficit stress and without foliar application of zinc oxide nano particles. Sarbaz had the highest amount of anthocyanin (0.3 μmol.g-1) in the treatment of severe water deficit stress and lack of foliar application of zinc oxide nano particles, which was not significantly different from Saravan. Also, the lowest amount of anthocyanin (0.146 μmol.g-1) was related to Fanuj in the treatment of severe water deficit stress with foliar application of zinc oxide nano particles. Severe water deficit stress reduced the amount of traits tested. Also, the Sarbaz showed good tolerance to water deficit stress conditions compared to other landraces. The foliar application of zinc oxide nano particles also improved plant growth and increased some of the tested traits under stress conditions. Manuscript profile -

Among the traits under study, leaf fresh weight, leaf dry weight, stem fresh weigh at 1% and plant hight, stem dry weight, total plant fresh weight and total plant dry weight at %5 levels of probabilities showed significant differences for their interaction between different treatments of titanium and different stage of development. The highest plant height, leaf dry weight and plant fresh weight and plant dry weight were produced when nano particles of titanium applied after flowering stage. Where as, the highest fresh leaf, fresh stem weight and total plant fresh weights were obtained when plants treated with titanium at flowering stage. On the other hand, dry weight of flowering branches showed significant negative correlation with GPX antioxidant enzyme. The lowest GPX antioxidant enzyme was produced when nano particles of titanium were applied after flowering stage at 0.01% probability level. As a whole, the results of this experiment suggest that there are significant differences among titanium treatments when they are applied at different growth stages of this plant. This study also showed that application of nano particles of titanium after flowering of this plant increased its flowering branches. Manuscript profile -

In this study, the green synthesis of copper oxide nanoparticles from the extract of Iranian violent flower and its anti-bacterial properties compared to two common antibiotics was investigated. First, aqueous extract of Iranian violent flower prepared and admixed with CuO solution at a concentration of 1 mM. After changing the color of extract, the reaction product was examined by spectrophotometric and X-ray diffraction. Finally, antibacterial properties of synthesized nanoparticles were investigated using disk diffusion method. Also, the MIC (minimum inhibitory concentration of growth and MBC (minimum bactericidal concentration) were determined by two methods of micro dilution and dilution in the tube. The synthesized copper oxide nanoparticles showed the most absorbance at 266 nm and had a spherical shape with an average size of 50-80 nm. The results of the antibacterial studies showed that the synthesized copper oxide nanoparticles had more antibacterial activity against staphylococcus aureus than Escherichia coli. The extract of Iranian violent flower has the ability of reducing CuO ion to copper oxide nanoparticles. Also, synthesized copper oxide nanoparticles have good antibacterial activities.
