Dye-sensitized solar cells (DSSCs) have gained considerable interest as alternatives to the semiconductor-based thin film solar cells. Natural dye sensitized solar cells have become promising candidates for the replacement of synthetic dyes. Graphene oxide exhibited impressive photoelectric properties, large surface area, high charge-carrier mobility, high conductance and fast electron transfer. Thus graphene oxide was considered as the most promising material for various potential applications. Nickel oxides have been of particular interest because of its good electro-catalytic properties, low toxicity and low cost, which made them suitable for photo-anode in dye sensitized solar cells. In the present work, a hybrid material consisting of nickel oxide nanoparticles anchored onto the nitrogen doped graphene oxide sheets was prepared by chemical precipitation method. The structural and morphological studies of the prepared nanocomposites were investigated by X-Ray diffraction analysis and electron microscopy (FE-SEM). The presence of functional groups in the synthesized nanocomposites was studied by Fourier transform infrared spectroscopy (FT-IR). The electrochemical activity of the prepared nanocomposites was investigated by cyclic voltammetry (CV). The prepared nanocomposites were suitable for dye sensitized solar cell applications","PeriodicalId":7285,"journal":{"name":"Advances in Applied Science Research","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78484100","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}

Orchids grow in nature through seeds but in the absence of appropriate hosts, they do not germinate in adequate number. This obstacle was overcome by adapting tissue culture technique for appropriate germination of orchids. In vitro techniques have been successfully carried out for the mass propagation of orchid plantlets. Hence, a preliminary study was carried out to develop a suitable protocol for mass multiplication of Pholidota pallida. MS (Murashige and Skoog) medium was found to be suitable for the asymbiotic seed germination of Pholidota pallida. MS medium supplemented with IAA (Indole-3-acetic acid), IBA (Indole-3butyric acid), BAP (6-Benzylaminopurine) and KIN (Kinetin) individually and in combinations induced direct protocorm like bodies.
