Öğe Genea lobulata, a new hypogeous ascomycete record for Turkish mycobiota(2019) Berber, Osman; Uzun, Yasin; Kaya, AbdullahThe hypogeous ascomycete species Genea lobulata is given as new record for the mycobiota of Turkey based on the collections from Ulukışla district of Niğde province. General descriptive characteristics of the species is summarized, and macroscopic photographs of fresh specimens and microscopic images obtained from dried specimens were provided.Öğe Plant biotechnology(Hindawi, 2013) Khawar, Khalid Mahmood; Onarıcı, Selma; Özel, Çiğdem Alev; Aasim, Muhammad; Bakhsh, Allah; Rao, Abdul QayyumIt is a privilege, pleasure, and honour to present this special issue to the international scientific community. The editorial board is confident that it is a truly good publication; as the papers published in this issue cover a broad spectrum of topics on plant biotechnology, that could be of wide interestÖğe Effect of au nanoparticles doping on the properties of tio2 thin films(Kaunas University of Technology, 2014) Gültekin, AytaçIn this study, pure and gold (Au) nanoparticles doped TiO2 thin films (Au/Ti = 10, 20, 30, 40 and 50 at%) were prepared by sol-gel method and the impact of Au nanoparticles doping on the optical, structural and morphological properties of these thin films was examined. All thin films were characterized using ultraviolet-visible-near infrared (UV-Vis-NIR) spectrophotometry, X-ray diffraction (XRD), transmission electron microscopy (TEM) and atomic force microscopy (AFM). The optical band gap of the thin films increases from 3.74 eV to 3.89 eV with the increase of Au nanoparticles concentrations due to the Moss-Burstein effect. XRD results show that all thin films have cubic poly-crystal structure and the intensities of peaks of the crystalline phase increased with the increase of Au nanoparticles concentrations. The AFM results indicate that the TiO2 thin films are formed from the nanoparticles and the grain size of the films is changed with Au doping level. Consequently, it is shown that the structural, morphological and optical properties of the TiO2 thin films could be changed by Au nanoparticles-doping.
