    • All-fiber nonlinearity-and dispersion-managed dissipative soliton nanotube mode-locked laser 

      Zhang Z.; Popa, D.; Wittwer, V. J.; Milana, S.; Hasan, T.; Jiang, Z.; Ferrari, A. C.; Ilday F. Ö. (American Institute of Physics, 2015)
      We report dissipative soliton generation from an Yb-doped all-fiber nonlinearity- and dispersion-managed nanotube mode-locked laser. A simple all-fiber ring cavity exploits a photonic crystal fiber for both nonlinearity ...
    • Atomic layer deposition of metal oxide thin films and nanostructures 

      Dönmez, İnci (Bilkent University, 2013)
      With the continuing scaling down of microelectronic integrated circuits and increasing need for three-dimensional stacking of functional layers, novel or improved growth techniques are required to deposit thin films with ...
    • Confined linear carbon chains as a route to bulk carbyne 

      Shi, L.; Rohringer, P.; Suenaga, K.; Niimi, Y.; Kotakoski, J.; Meyer, J. C.; Peterlik, H.; Wanko, M.; Cahangirov, S.; Rubio, A.; Lapin, Z. J.; Novotny, L.; Ayala, P.; Pichler, T. (Nature Publishing Group, 2016-04)
      Strong chemical activity and extreme instability in ambient conditions characterize carbyne, an infinite sp1 hybridized carbon chain. As a result, much less has been explored about carbyne as compared to other carbon ...
    • Generation of phospholipid vesicle-nanotube networks and transport of molecules therein 

      Jesorka, A.; Stepanyants, N.; Zhang H.; Ortmen, B.; Hakonen, B.; Orwar O. (2011)
      We describe micromanipulation and microinjection procedures for the fabrication of soft-matter networks consisting of lipid bilayer nanotubes and surface-immobilized vesicles. These biomimetic membrane systems feature ...
    • Magic gold nanotubes 

      Senger, R.T.; Daǧ, S.; Çiraci, S. (2005)
      In recent ultra-high-vacuum transmission-electron-microscopy experiments evidence is found for the formation of suspended gold single-wall nanotubes (SWNTs) composed of five helical strands. Similar to carbon nanotubes, ...
    • Metal coverage on single-wall carbon nanotubes : metal nanoring and nanotube formation 

      Bağcı, V M Kemal (Bilkent University, 2002)
      The carbon nanotubes are welcomed as the basis element for electronic and opto-electronic devices of nanometers size, the size of a few atoms. The question of crucial importance in the physics of utilization of nanotubes ...
    • Preparation of Al 2O 3and AlN nanotubes by atomic layer deposition 

      Ozgit, C.; Kayaci F.; Donmez I.; Cagatay, E.; Uyar, T.; Biyikli, N. (2012)
      Al 2O 3 and AlN nanotubes were fabricated by depositing conformal thin films via atomic layer deposition (ALD) on electrospun nylon 66 (PA66) nanofiber templates. Depositions were carried out at 200°C, using trimethylaluminum ...
    • Size-controlled conformal nanofabrication of biotemplated three-dimensional TiO2 and ZnO nanonetworks 

      Ceylan H.; Ozgit-Akgun, C.; Erkal, T.S.; Donmez I.; Garifullin, R.; Tekinay, A.B.; Usta H.; Biyikli, N.; Guler, M.O. (2013)
      A solvent-free fabrication of TiO2 and ZnO nanonetworks is demonstrated by using supramolecular nanotemplates with high coating conformity, uniformity, and atomic scale size control. Deposition of TiO2 and ZnO on ...
    • Tailoring self-organized nanostructured morphologies in kilometer-long polymer fiber 

      Khudiyev, T.; Tobail, O.; Bayindir, M. (Nature Publishing Group, 2014-05-06)
      While nanowires and nanospheres have been utilized in the design of a diverse array of nanoscale devices, recent schemes frequently require nanoscale architectures of higher complexity. However, conventional techniques are ...
    • Theoretical study of hydrogen adsorption in Ti-decorated capped carbon nanotube 

      Niaz S.; Abbasian H.; Badar M.A.; Anwar-ul-Haq M.; Karayel A. (Taylor and Francis Ltd., 2017)
      We present ab initio study using dispersion-corrected density functional theory calculations to investigate the hydrogen interaction with Ti-coated, one end closed, single-walled carbon nanotube (SWCNT). Our results ...
    • A theoretical study on silicon and III-V compound nanotubes 

      Durgun, E.; Çiraci, S. (2005)
      In this paper we present a theoretical study on single-wall silicon and III-V compound nanotubes. First principles plane wave calculations within density functional theory are used to predict energetics and electronic ...
