A method developed for analyzes of large number of aerosol samples using Energy Dispersive X-Ray Fluorescence (EDXRF) and its performance were discussed in this manuscript. Atmospheric aerosol samples evaluated in this study were collected on cellulose fiber (Whatman-41) filters, employing a Hi-Vol sampler, at a monitoring station located on the Mediterranean coast of Turkey. between 1993 and 2001. Approximately 1700 samples were collected in this period. Six-hundred of these samples were analyzed by instrumental neutron activation (INAA), and the rest were archived. EDXRF was selected as an analytical technique to analyze 1700 aerosol samples because of its speed and non-destructive nature. However, analysis of aerosol samples collected on fiber filters with a surface technique such as EDXRF was a challenge. Penetration depth calculation performed in this study revealed that EDXRF can obtain information from top 150 mu m of our fiber filter material. Calibration of the instrument with currently available thin film standards caused unsatisfactory results since the actual penetration depth of particles into fiber filters were much deeper than 150 mu m. A method was developed in this manuscript to analyze fiber filter samples quickly with XRF. Two hundred samples that were analyzed by INAA were divided into two equal batches. One of these batches was used to calibrate the XRF and the second batch was used for verification. The results showed that developed method can be reliably used for routine analysis of fiber samples loaded with ambient aerosol.

Determination of ion dose and profiles in Ge-74 and Sn-120 implanted silicon layers by PIXE, NAA, RBS and SIMS Belin, B; Bode, P; Turan, Raşit; Van Meerten, TG (2004-01-01) Implanted Ge-74 and Sn-121 concentrations in silicon (Si) layers were investigated by particle induced X-ray emission (PIXE), instrumental neutron activation analysis (INAA), Rutherford backscattering spectrometry (RBS) and secondary ion mass spectrometry (SIMS). Slight differences were observed in the results obtained. It was shown that PIXE and INAA are as powerful as the traditional RBS and SIMS spectroscopy for the investigation of thin layered Si.
A Novel Numerical Technique for Analyzing Metasurfaces ÖZGÜN, ÖZLEM; Mittra, Raj; Kuzuoğlu, Mustafa (2019-12-31) This work presents a novel technique for efficient numerical modeling of electromagnetic scattering from metasurfaces comprising of truncated periodic or locally-varying quasi-periodic surfaces. The proposed technique hybridizes the periodic Finite Element Method (FEM) with the Method of Moments (MoM) to develop an algorithm far more efficient than conventional numerical methods for electromagnetic scattering from arbitrary objects. The key feature of the proposed algorithm is that it takes advantage of the...
A novel method to measure the glass and melting transitions of pharmaceutical powders Abiad, Mohamad G.; Gonzalez, David C.; Mert, Behiç; Campanella, Osvaldo H.; Carvajal, M. Teresa (Elsevier BV, 2010-08-30) A method to measure thermo-mechanical properties of pharmaceutical and polymeric powders was developed The measurements are conducted by characterizing the material's response to applied acoustic waves Measurements were performed using griseofulvin, felodipine and indomethacin as model drugs and polyethylene oxide (MW 200,000, 900,000, 2,000,000 Da) as model polymers. The method employed measures the mechanical Impedance enabled the calculation of the powder theological and thermo-mechanical properties. Mea...
A theoretical study of chemical doping and width effect on zigzag graphene nanoribbons Pekoz, Rengin; Erkoç, Şakir (Elsevier BV, 2009-12-01) The energetics and the electronic properties of nitrogen- and boron-doped graphene nanoribbons with zigzag edges have been investigated using density functional theory calculations. For the optimized geometry configurations, vibrational frequency analysis and wavefunction stability tests have been carried out. Different doping site optimizations for a model nanoribbon have been performed and formation energy values of these sites revealed that zigzag edgesite for both of the dopants were the most favorable ...
A Transformation Media Based Approach for Efficient Monte Carlo Analysis of Scattering From Rough Surfaces With Objects Ozgun, Ozlem; Kuzuoğlu, Mustafa (2013-03-01) This paper presents a computational model that utilizes transformation-based metamaterials to enhance the performance of numerical modeling methods for achieving the statistical characterization of two-dimensional electromagnetic scattering from objects on or above one-dimensional rough sea surfaces. Monte Carlo simulation of the rough surface scattering problem by means of differential equation-based finite methods (such as finite element or finite difference methods) usually places a heavy burden on compu...
