X chromosome inactivation and female predisposition to autoimmunity
(2008)[No abstract available] -
X chromosome inactivation in female predisposition to autoimmunity
(Bilkent University, 2008)The high female preponderance is thought to be important in identifying the etiological factors. Sex hormones, pregnancy related microchimerism, and environmental factors are investigated as likely candidates. Disturbed ... -
X-band CPW high power amplifier design by GAN based MMIC technology
(Bilkent University, 2016-06)The developments in defense industry, telecommunication and satellite systems have gradually increased the necessities for the small and compact Power Ampli- fiers (PAs) with high output powers and gains. Monolithic Microwave ... -
X-band low phase noise mmic vco & high power mmic spdt design
(Bilkent University, 2014)Generally the tuning bandwidth (BW) of a VCO is smaller than the tuning BW of the resonant circuit itself. Using proper components with right topology can handle this problem. In order to overcome this problem and improve ... -
X-ray induced reduction of Au and Pt ions on silicon substrates
(2007)Prolonged exposure to X-rays of HAuCl4, PtCl4 and their mixtures, deposited from an aqueous solution onto a silicon substrate, causes chemical reduction of the metal ions to their metallic states. The corresponding oxidation ... -
X-ray photoelectron spectroscopic analysis of Si nanoclusters in SiO 2 matrix
(American Chemical Society, 2006)We investigated silicon nanoclusters Si(nc) in a SiO2 matrix prepared by the plasma-enhanced chemical vapor deposition technique, using X-ray photoelectron spectroscopy (XPS) with external voltage stimuli in both static ... -
X-ray photoelectron spectroscopic and in-situ infrared investigation of a Ru/SiO2 catalyst
(Bilkent University, 1997)A 4 wt% Ru/Si02 catalyst which was previously prepared via an incipient wetness technique using a ruthenium nitrosyl-nitrate [Ru(N0)(N03)3] solution and a commercially available precursor (ruthenium nitrosyl-nitrate) were ... -
X-ray photoelectron spectroscopic characterization of Au collected with atom trapping on silica for atomic absorption spectrometry
(1997)The nature of analyte species collected on a cooled silica tube for atom-trapping atomic absorption spectrometric determination was investigated with the use of X-ray photoelctron spectroscopy (XPS). An XPS spectrum of ... -
X-ray photoelectron spectroscopic investigation of conducting polymer blends
(1996)Electrochemically prepared films of conducting polymers of polypyrrole and polythiophene and their blends with polyamide have been investigated by X-ray photoelectron spectroscopy. In the N1s region of the spectra of films ... -
X-ray photoelectron spectroscopic investigation of gold particles deposited on (formula) system
(Bilkent University, 2003)Gold particles on SiO2/Si system were investigated by X-ray Photoelectron Spectroscopy (XPS) technique. A suitable reference point was first established in order to investigate the physical/chemical factors affecting ... -
X-ray photoelectron spectroscopy for identification of morphological defects and disorders in graphene devices
(AVS Science and Technology Society, 2016)The progress in the development of graphene devices is promising, and they are now considered as an option for the current Si-based electronics. However, the structural defects in graphene may strongly influence the local ... -
X-ray photoelectron spectroscopy for resistance-capacitance measurements of surface structures
(2005)In x-ray photoemission measurements, differential charging causes the measured binding energy difference between the Si 2p of the oxide and the silicon substrate to vary nonlinearly as a function of the applied external ... -

X-ray photoemission for probing charging/discharging dynamics
(American Chemical Society, 2006)A novel technique is introduced for probing charging/discharging dynamics of dielectric materials in which X-ray photoemission data is recorded while the sample rod is subjected to ± 10.0 V square-wave pulses with varying ... -
X-ray-induced production of gold nanoparticles on a SiO2/Si system and in a poly(methyl methacrylate) matrix
(2005)Prolonged exposure to X-rays of HAuCl4 deposited from an aqueous solution onto a SiO2/Si substrate or into a poly(methyl methacrylate) (PMMA) matrix induces reduction of the Au3+ ions to Au0 and subsequent nucleation to ... -
