Investigation of two new lyotropic liquid crystalline systems : [Zn (formula) and [Zn (formula)
(Bilkent University, 2008)
The transition metal aqua complex salts (TMS) can be dissolved in oligo
(ethylene oxide) type non-ionic surfactants (CnH2n+1(CH2CH2O)mOH, denoted as
CnEOm) with very high salt/surfactant ratios to form lyotropic liquid ...
Investigation on electrical charging/discharging properties of thin ps/pmma polymeric films by dynamic x-ray photoelectron spectroscopy
(Bilkent University, 2008)
Electrical charging/discharging properties of thin layers of spin coated pure PS
polystyrene (PS), and pure poly(methyl methacrylate), (PMMA) and an immiscible
PS/PMMA blend are studied with externally applied DC and ...
Surface enhanced raman scattering from Au and Ag nanoparticle coated magnetic microspheres
(Bilkent University, 2008)
A novel SERS substrate was prepared by coating Au or Ag nanoparticles onto
magnetic microspheres prepared by a modified suspension polymerization method.
The micron-sized magnetic microspheres were prepared in two steps: ...
Investigation of electrical properties of surface structures by X-Ray photoelectron spectroscopic technique under external voltage stimuli
(Bilkent University, 2005)
Electrical properties of surface structures are analyzed using XPS (X-Ray
Photoelectron Spectroscopy) by means of external stimuli together with a novel technique
allowing the user to record 200 conventional spectra in ...
Identification, stability and reactivity of NOx adsorbed species on titania-supported manganese catalysts
(Bilkent University, 2001)
The needs of improved fuel economy, and lower emission of green-house gases
such as CO2, is projected to increase the demand for diesel engines through the world.
These engines operate at air/fuel ratio higher than ...
Electronic structure analysis and density functional study of an alternating donor/acceptor polymer
(Bilkent University, 2001)
Conducting polymers have attracted great attention for the last two decades
because of their potential applications in many fields. One of the major goals for the
scientists who are studying in this field is to synthesize ...
The mechanism of hydroquinone assisted photodegradation of PVC
(Bilkent University, 2002)
Pure poly(vinyl chloride) (PVC) degrades upon exposure of UV radiation (λ <300 nm)
by the loss of HCl and formation of long conjugated structures known as polyenes. The
mechanism of this process is fully understood and ...
A desity functional study on narrow band gap donor-acceptor type conducting polymers
(Bilkent University, 2004)
The band gap is one of the most important factors for controlling the physical
properties. The search for polymers having narrow band gaps is a current topic.
Tuning of the band gap by structural modification is possible. ...
Investigation of the crystallinity and orientation of polypropylene with respect to temperature changes using FT-IR, WRD, and Raman techniques
(Bilkent University, 2004)
Having good mechanical and barrier properties, polypropylene films are widely used
in food-packing industry. The relation of crystallinity and orientation of
polypropylene with these properties are well known. Temperature ...
Solid-solution of Cd(formula)Zn(formula)S nanocrystals in the channels of mesostructured silica films
(Bilkent University, 2006)
Mesostructured silica can be used as a reaction medium to produce solidsolution
of Cd1-xZnxS nanocrystals as thin films. These films were synthesized from
oligo(ethylene oxide) non-ionic surfactant (CH3(CH2)11(OCH2CH2)10OH, ...
