Evidence indicates that noise exposure can lead to anxiety-like behaviors. In recent years, advances in nanotechnology have favorably impacted industrial productions. In the present study, we aimed to evaluate the effect of Zinc/Iron oxide nanocomposites on anxiety-like behavior. Using gelatin, Zinc/Iron oxide nanocomposites were synthesized by the sol-gel modified method. Four groups of rats were exposed to sound stress for 12 days. Three groups received 1.25, 2.5, and 5 mg/kg of Zinc/Iron oxide nanocomposites before the noise stress. Also, three control animals received the same doses of the nanocomposites. One group of the stressed (ST) and control (CO) rats received saline. The animals were introduced to the elevated plus maze (EPM) for the assessment of anxiety. Entry to closed arms, duration of stay in open arms were considered for data analysis. We observed a significant difference between the behavior of the CO and ST animals so that the latter group showed more anxiety compared to the former one. Concerning the effect of Zinc/Iron oxide nanocomposites, the data analysis confirmed the positive effect of the dose of 2.5 mg/kg where the stressed animals treated with this dose of the nanocomposites considerably improved their normal performance in the EPM.","PeriodicalId":16523,"journal":{"name":"Journal of Nanostructures","volume":"10 1","pages":"702-712"},"PeriodicalIF":1.4,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45952845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The as-prepared hetrostructure material was characterized by X-ray diffraction, Fourier Transform Infrared Spectrometer, energy dispersive X-ray spectroscopy, ultraviolet-visible diffuse reflection spectra, scanning and transmission electron microscopy. The photodegradation of rhodamine B by the synthesized photocatalysts was investigated under UV irradiation and visible light. The results showed that immobilization of TiO2 on the surface and inside the photocatalytic structure enhanced the degradation of the pollutant. The band gap energy of the synthesized TiO2/en-MIL-101(Cr) measured by ultraviolet-visible diffuse reflection spectra showed that an insignificant shift to lower energy was situated after immobilization onto the structure of the supports. The relationship between the photocatalytic activity and the structure of TiO2/en-MIL-101(Cr) hetrostructure was discussed. The degradation efficiency of 84% and 77% of rhodamine B was respectively obtained by TiO2/en-MIL-101(Cr) under Uv and visible light, respectively.

The extracted dyes were characterized with the aid of UV–Vis and Fourier transform infrared (FT-IR) spectroscopies. The FT-IR results revealed the presence of hydroxyl groups in the chemical structures of the natural dyes, improving the interaction of between photosensitizer and TiO2 surface in solar cell devices. In addition, photoelectrochemical performance of the DSSCs based on the natural dyes illustrated short-circuit photocurrent (Jsc) and open-circuit voltages (Voc) ranging from 0.5 to 2.36 mA/cm2 and 0.38 to 0.62 V, respectively. Since cyanidin- glucoside compounds were the main pigment of brassica oleracea, interaction between plenty of hydroxyl groups of these compounds and TiO2 surface was very efficient, this sensitizer owned the best photovoltaic performance among all the natural dyes.","PeriodicalId":16523,"journal":{"name":"Journal of Nanostructures","volume":"10 1","pages":"691-701"},"PeriodicalIF":1.4,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48413128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CTAB (Cetyltrimethylammonium bromide), TSC (Trisodium citrate), and TX-100 (Triton X-100) as cationic, anionic, and nonionic surfactant respectively are used to study their effect on the particle size, morphology, and their stability. The synthesized particles are characterized by XRD, FE-SEM, EDAX, elemental mapping, TEM, HR-TEM, XPS and FT-IR, TGA, DTG, and DTA techniques. UV-Vis spectroscopy is used to monitor the synthesis of nanoparticles. The XRD patterns of all samples confirm that Ir-Sn BMNP are amorphous in nature. The influence of surfactant on the morphology and particle size of Ir-Sn BMNP samples was examined by the FE-SEM technique. The FE-SEM figures demonstrate that the particles of bimetal are in nano size, highly dispersed, and pseudo spherical in shape with smooth surfaces. The approximate crystallite (particle/grain) size of CTAB, TSC, and TX-100 assisted samples are ~1.39 nm (39 nm), ~2.2 nm (59 nm), and ~5.79 nm (89 nm) respectively, which are estimated from TEM and FE-SEM images. The presence and distribution of Ir and Sn elements in the BMNP is determined through EDAX and elemental mapping respectively. These techniques show that CTAB assisted Ir-Sn BMNP sample is in alloy form but TSC and TX-100 samples are in core-shell form, where the Ir core is surrounded by Sn shell. The XPS confirms the metallic state (Ir0), and the dual valence state of Sn (Sn2+ and Sn4+) is in the Sn 3d core level.","PeriodicalId":16523,"journal":{"name":"Journal of Nanostructures","volume":"10 1","pages":"846-862"},"PeriodicalIF":1.4,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44605617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
