In this study, an easy to construct and sensitive intracavity fiber loop ring down spectrometer was built by commercially available basic components and its application on chemical sensing is presented. System performance was investigated by using various acetylene/nitrogen gas mixtures as a function of total pressure (between 25 and 65 psia) in sensing region and a calibration curve is established. The instrument can achieve a limit of detection of 0.1% without a FBG and/or EDFA or a need for a complicated design. Moreover, the detection limit can be further improved by working at higher pressures. With the current design of the system, the change in type and/or concentration of species in the sensor region can be monitored in real time.

Multifunctional metamaterial sensor applications based on chiral nihility BAKIR, MEHMET; KARAASLAN, MUHARREM; AKGÖL, OĞUZHAN; Sabah, Cumali (2017-11-01) In this paper, chiral nihility based pressure, density, temperature and moisture content metamaterial sensor applications are investigated in detail. A "chiral nihility'' medium in which both the permittivity and the permeability tend to zero is investigated. Gammadion shaped resonators particularly designed for chiral nihility are introduced. Bandwidths and signal strengths show admissible results. Simulation and experimental results prove that chiral nihility occurred at the resonance frequencies when med...
Energy harvesting from piezoelectric stacks via impacting beam Özpak, Yiğit; Çalışkan, Mehmet; Department of Mechanical Engineering (2014) Piezoelectric materials can be used for energy harvesting from ambient vibration due to their high power density and ease of application. Two basic methods, namely, tuning the natural frequency to the operational frequency and increasing the operation bandwidth of the harvester are commonly employed to maximize the energy harvested from piezoelectric materials. Majority of the studies performed in recent years focus mostly on tuning the natural frequency of the harvester. However, small deviations in operat...
Metamaterial Sensor Applications Based on Broadside Coupled SRR and V Shaped Resonator Structures EKMEKÇİ, EVREN; Sayan, Gönül (2011-07-08) In this study, the use of broadside-coupled SRR (BC-SRR) metamaterial topology is suggested for pressure, temperature, humidity and concentration sensor applications. Also, the use of V-shaped resonator topology is suggested for pressure sensor application. The feasibility of such sensors are demonstrated by numerical simulations for microwave region under magnetic excitation.
Electrocatalyst development and modeling of nonisothermal two-phase flow for PEM fuel cells Fıçıcılar, Berker; Eroğlu, İnci; Department of Chemical Engineering (2011) A macro-homogeneous, nonisothermal, two-phase, and steady state mathematical model is developed to investigate water and thermal management in polymer electrolyte membrane (PEM) fuel cells. An original two-phase energy balance approach is used to catch the thermal transport phenomena in cases when there is a signi cant temperature di erence between the fuel cell temperature and the reactants inlet temperatures like during cold start-up. Model considers in depth electrode kinetics for both anode and cathode ...
Laser induced periodic surface structuring for surface enhanced raman spectroscopy Özkarslıgil, Zeynep Tuğçe; Bek, Alpan; Department of Physics (2020) In this study, our aim is to fabricate and characterize efficient substrates of surface enhanced Raman spectroscopy (SERS) utilizing the field enhancement due to hot spots made by recently developed method of laser induced periodic surface structuring (LIPSS). LIPSS is a cost-effective technique for rapid processing of almost any materials compared to conventional lithography methods. Coating of a thin silver film on LIPSS applied substrate surface provides to observe the localized surface plasmon effect fo...
