    • Chiral ceramic nanoparticles and peptide catalysis 

      Jiang S.; Chekini, M.; Qu, Z.-B.; Wang Y.; Yeltik A.; Liu, Y.; Kotlyar, A.; Zhang, T.; Li, B.; Demir, H. V.; Kotov, N. A. (American Chemical Society, 2017)
      The chirality of nanoparticles (NPs) and their assemblies has been investigated predominantly for noble metals and II-VI semiconductors. However, ceramic NPs represent the majority of nanoscale materials in nature. The ...
    • MIMIM photodetectors using plasmonically enhanced MIM absorbers 

      Abedini Dereshgi, S.; Okyay, A. K. (SPIE, 2017)
      We demonstrate super absorbing metal-insulator-metal (MIM) stacks and MIMIM photosensitive devices operating at visible and near-infrared (VIS-NIR) spectrum, where absorbing (top) MIM and photocollecting (bottom) MIM can ...
    • Multispectral plasmonic structures using native aluminum oxide and aluminum 

      Ayas, S.; Bakan, G.; Dana, A. (OSA - The Optical Society, 2017)
      We report the use of native aluminum oxide to fabricate periodic metal-insulator-metal resonators with simultaneous resonances in the visible and IR wavelengths. The cavity size is in the order of λ3/25000 in the NIR.
    • Nonlinear laser lithography for indefinitely large-area nanostructuring with femtosecond pulses 

      Öktem, B.; Pavlov, I.; Ilday, S.; Kalaycıoǧlu, H.; Rybak, A.; Yavaş, S.; Erdoǧan, M.; Ilday F. Ö. (Nature publishing group, 2013)
      Dynamical systems based on the interplay of nonlinear feedback mechanisms are ubiquitous in nature. Well-understood examples from photonics include mode locking and a broad class of fractal optics, including self-similarity. ...
    • Photocatalytic conversion of nitric oxide on titanium dioxide: cryotrapping of reaction products for online monitoring by mass spectrometry 

      Lu, W.; Olaitan, A. D.; Brantley, M. R.; Zekavat, B.; Erdogan, D. A.; Ozensoy, E.; Solouki, T. (American Chemical Society, 2016)
      Details of coupling a catalytic reaction chamber to a liquid nitrogen-cooled cryofocuser/triple quadrupole mass spectrometer for online monitoring of nitric oxide (NO) photocatalytic reaction products are presented. Cryogenic ...
    • The substrate temperature dependent electrical properties of titanium dioxide thin films 

      Yildiz, A.; Lisesivdin, S.B.; Kasap, M.; Mardare, D. (2010)
      Titanium dioxide thin films were obtained by a dc sputtering technique onto heated glass substrates. The relationship between the substrate temperature and the electrical properties of the films was investigated. Electrical ...
    • Tailoring insoluble nanobelts into soluble anti-UV nanopotpourris 

      Wang, J.; Sun, X. W.; Jiao, Z.; Khoo, E.; Lee, P. S.; Ma, J.; Demir, H. V. (Royal Society of Chemistry, 2011)
      Soluble, transparent and anti-UV nanopotpourris have been prepared by tailoring long nanobelts. The strains and layered structures facilitate the breaking of the as-synthesized nanobelts under an applied mechanical action. ...
    • The tight-binding approach to the corundum-structure d compounds 

      Ivanov, V. A. (Institute of Physics Publishing Ltd., 1994)
      The analysis of electronic structures has been carried out for the transition-metal compounds showing the corundum-type crystal symmetry using the suggested tight-binding method for interacting bands. With the self-consistent ...
    • Toxicity of lanthanum oxide (La2O3) nanoparticles in aquatic environments 

      Balusamy, B.; Taştan, B. E.; Ergen, S. F.; Uyar T.; Tekinay, T. (Royal Society of Chemistry, 2015)
      This study demonstrates the acute toxicity of lanthanum oxide nanoparticles (La2O3 NP) on two sentinel aquatic species, fresh-water microalgae Chlorella sp. and the crustacean Daphnia magna. The morphology, size and charge ...
    • Visible photoluminescence from SiOx films grown by low temperature plasma enhanced chemical vapor deposition 

      Timofeev, F. N.; Aydinli, A.; Ellialtioglu, R.; Turkoglu, K.; Gure, M.; Mikhailov, V. N.; Lavrova, O. A. (Pergamon Press, 1995)
      a-SiOx films of varying stoichiometry have been prepared by low temperature plasma enhanced chemical vapor deposition. The majority of films showed photoluminescence (PL) and films prepared in a narrow range of gas flows ...
