The Bilkent University Open Access Articles collection consists of scholarly articles written by Bilkent-affiliated authors that are made available through BUIR under the Bilkent Faculty Open Access Policy, or under related publisher agreements.

Version details are supplied for each paper in the collection:

  • Original manuscript: author's manuscript prior to formal peer review
  • Author's final manuscript: final author's manuscript post peer review, without publisher's formatting or copy editing
  • Final published version: final published article, as it appeared in a journal, conference proceedings, or other formally published context (this version appears here only if allowable under publisher's policy)

Post peer-reviewed scholarly articles are available through BUIR collections, such as those for departments, labs, and research centers.

  • Future outlook 

    Erdem, Talha; Demir, Hilmi Volkan (Springer, 2019-01)
    In this final Chapter, we present a future perspective for the light source design. We discuss the existing problems and briefly introduce new material systems and device architectures that can overcome the current issues.
  • How to design quality light sources with discrete color components 

    Erdem, Talha; Demir, Hilmi Volkan (Springer, 2019-01)
    White light sources using discrete emitters require careful design and optimization. The first step of the design should be determining the intended use of the light source so that application specific requirements can be ...
  • Common white light sources 

    Erdem, Talha; Demir, Hilmi Volkan (Springer, 2019-01)
    In this Chapter we describe the features of common light sources. We first present the spectral features of the sun and discuss its colorimetric properties. Next, we summarize the properties of traditional light sources ...
  • Metrics for light source design 

    Erdem, Talha; Demir, Hilmi Volkan (Springer, 2019-01)
    In this part of this brief, we summarize the metrics that need to be considered for designing light sources. We start with metrics on the shade of color and then continue with color rendering and photometry.
  • Colorimetry for LED lighting 

    Erdem, Talha; Demir, Hilmi Volkan (Springer, 2019-01)
    In this Chapter, we explain the basics of colorimetry and introduce the colorimetric tools useful for designing light sources.
  • Light stimulus and human eye 

    Erdem, Talha; Demir, Hilmi Volkan (Springer, 2019-01)
    In this Chapter, we summarize the structure of the human eye and introduce the sensitivity functions of various photoreceptors and present the visual regimes and corresponding eye sensitivity functions.
  • Civil-military relations 

    Heper, Metin (Taylor & Francis, 2019-04-09)
    Until recent decades, the military, on the whole, played a special role both in the Ottoman and Republican polities. In circa 1299, a military force, at the time consisting of warlords, formed the Ottoman principality. ...
  • Cucurbituril containing supramolecular nanomaterials 

    Khan, Rehan; Tuncel, Dönüş (The Royal Society of Chemistry, 2019-01)
    National Magnetic Resonance Research Center UMRAM Cucurbituril-based supramolecular nanomaterials are getting increasing attention due to their tailorable properties and functions. By making use of the host–guest chemistry ...
  • Cucurbituril-assisted supramolecular polymeric hydrogels 

    Khaligh, Aisan; Tuncel, Dönüş (The Royal Society of Chemistry, 2019-01)
    Cucurbituril-assisted supramolecular polymeric hydrogels (CB-SPHs), formed by supramolecular cross-linking of polymer chains via directional noncovalent interactions, are a novel class of three-dimensional cross-linked ...
  • Cucurbituril homologues and derivatives: syntheses and functionalization 

    Koç, Ahmet; Tuncel, Dönüş (The Royal Society of Chemistry, 2019-01)
    In this chapter, we discuss the syntheses and functionalization of cucurbituril (CB[n]) homologues and derivatives. We begin with a historical background on CB[n] chemistry, from the first known CB[n] homologue, CB[6], to ...
  • Intrinsic oscillations of auditory networks in schizophrenia and bipolar disorder 

    Atagün, M. İ.; Akın, B.; Algın, Oktay; Sıkoğlu, E. M.; Can, S. S.; Kaymak, S. U.; Çayköylü, A.; Moore, C.; Phillips, M.; Ongur, D. (Yerküre Tanıtım ve Yayıncılık Hizmetleri A. Ş., 2019)
    Objective: Several types of evidence have shown that auditory networks are dysfunctional in schizophrenia (Sch) and bipolar disorders (BD). Auditory cortices show abnormalities in hallucinations or during remission. This ...
  • Glycosylated porphyrin-cucurbituril conjugate for photodynamic inactivation of bacteria and doxorubicin carriage for anticancer drug delivery 

    Özkan, Melis; Keser, Yağmur; Koç, Ahmet; Tuncel, Dönüş (World Scientific Publishing, 2019-10)
    Porphyrin derivatives are highly attractive in the construction of multifunctional molecular platforms with interesting properties and applications. In this regard, we report here the use of a multifunctional porphyrin-based ...
  • Complete intersection monomial curves and the Cohen—Macaulayness of their tangent cones 

    Katsabekis, Anargyros (World Scientific Publishing, 2019)
    Let C(n) be a complete intersection monomial curve in the 4-dimensional affine space. In this paper we study the complete intersection property of the monomial curve C(n + wv), where w > 0 is an integer and v ∈ ℕ4. In ...
  • Two-dimensional Bose polaron using diffusion Monte Carlo method 

    Akatürk, Emre; Tanatar, Bilal (World Scientific Publishing, 2019-09)
