The present paper focuses on development of a compact photo-acoustic sensor using inexpensive components for glucose analysis. An amplitude-stabilized wavelength-tunable single-mode external cavity diode laser operating around 1050 nm was realized and characterized for the use of laser beam as an excitation light source. In the established setup, a fine tuning range of 9 GHz was achieved. The glucose solution was obtained by diluting D-glucose in sterile water. The acoustic signal generated by the optical excitation was detected via a chip piezoelectric film transducer. A detection limit of 50 mM (900 mg/dl) was achieved. The device may be of great interest for its applications in medicine and health monitoring. The sensor is promising for non-invasive in vivo glucose measurements from interstitial fluid.

Photoconductivity of organic semiconductor polymers studied by time-resolved THz-TDS Esentürk, Okan; Heilweil, Edwin J. (null; 2007-12-01) This study employs optical-pump terahertzprobe time-domain spectroscopy to measure relative carrier mobilities of semiconductor organic polymer films of poly-3-hexylthiophene (P3HT) and poly(2,5-bis(3-tetradecylthiophen-2-yi) thieno[3,2-b]thiophene) (PBTTT) polymers and these results directly correlate to recently reported electrical device mobility measurements.. An approximately four-fold increase in mobility of P3HT is observed with molecular weight increase from c.a. 18 kD to 150 kD where the intrinsic ...
Dual-band high-frequency metamaterial absorber based on patch resonator for solar cell applications and its enhancement with graphene layers Ustunsoy, Mehmet Pasa; Sabah, Cumali (2016-12-05) In this paper, a dual-band high-frequency metamaterial absorber based on patch resonator is designed and analyzed for solar cells. In order to obtain a metamaterial absorber, metal-semiconductor-metal layers are combined. The results of the designed structure are shown in the infrared and visible ranges of solar spectrum. Structural parameters and dimensions of the device have a significant importance on the performance of the designed absorber. The simulations are carried out with full-wave electromagnetic...
Development of a scada control system for a weighing and bagging machine Aykaç, Emel Sinem; Balkan, Raif Tuna; Department of Mechanical Engineering (2010) In this thesis study, a prototype is designed in order to improve the weighing accuracy of the weighing and packaging machine that used in sugar factories. The unavoidable factory conditions cause weighing and packaging machine to do weighing errors. In order to correct these errors, the prototype produced in this study was designed as a quality control unit which will take the excess sugar and fill the deficient sugar in the sacks. Because of being small and having an easy installation, the application of ...
Dynamic stiffness-based test systems for viscoelastic material characterization: Design considerations Özgen, Gökhan Osman; Batihan, Ali Cagri (2012-07-24) In this paper, several important design issues for viscoelastic material characterization test systems which utilize dynamic stiffness measurements are discussed. These discussions are focused on structural dynamics aspects of the design of these test systems. These test systems are used to experimentally obtain the complex modulus of viscoelastic solids such as rubber, plastics, etc. Various standards exist on dynamic stiffness-based viscoelastic material characterization test methods, which give general g...
Optical design of TCO-free interconnecting layer for all-perovskite tandem solar cells Koc, Mehmet; Ameri, Mohsen; Yerci, Selçuk (2021-07-12) Organic-inorganic hybrid perovskite materials are excellent candidates as light absorbers in tandem solar cells with advantages of tunable bandgaps, high absorption coefficients, and facile and low-cost fabrication processes. As the key component of a tandem structure, the interconnecting layer (ICL) requires optical transparency, efficient carrier recombination, and facile up-scalability. To demonstrate the feasibility of an efficient TCO-free ICL in all-perovskite tandem solar cell devices, we have perfor...
