Microwave metamaterial absorber for sensing applications BAKIR, MEHMET; KARAASLAN, MUHARREM; ÜNAL, EMİN; AKGÖL, OĞUZHAN; Sabah, C. (Elsevier BV, 2017-12-01) A metamaterial absorber (MA) based sensor is designed and analysed for various important applications including pressure, temperature, density, and humidity sensing. Material parameters, as well as equivalent circuit model have been extracted and explained. After obtaining a perfect absorption (PA) at around 6.46 GHz and 7.68 GHz, surface current distributions at resonance points have been explained. Since bandwidth and applicability to different sensor applications are important for metamaterial sensor app...
Microwave decontamination process for hummus: A computational study with experimental validation Son, Ezgi; Coskun, Eda; Ozturk, Samet; BULDUK, KÜBRA; AKPINAR, MERVE; Mert, Behiç; ERDOĞDU, FERRUH (2022-12-01) © 2022There has been an increasing demand for healthy snacks, and hummus is preferred as a plant-based product its rich protein content. Its increased consumption, on the other hand, has raised food safety issues with linkages to Listeria outbreak and a recent Salmonella related recall. These were observed in ready-to-eat hummus and indicated the requirement of further processing. Conventional thermal processes might require longer times with negative impact on the quality due to the high viscosity of hummu...
Microwave sintering and characterization of soft magnetic powder metallurgical Ni-Fe alloys Erdem, Derya; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2011) In this study, prealloyed austenitic stainless steel and premixed soft magnetic Ni-Fe permalloy compacts were consolidated through microwave and conventional sintering routes at combinations of various sintering temperatures and compaction pressures. Sintered alloys were characterized in terms of their densification, microstructural evolution as well as mechanical and magnetic properties. The effect of sintering method in terms of the applied sintering parameters on the final properties of the compacts were...
Microwave-Assisted Simultaneous Synthesis of Conducting and Non-Conducting Polymers from Potassium 2,4,6-Tribromophenolate Celik, Gueler Bayrakli; Kisakurek, Duygu (Springer Science and Business Media LLC, 2009-01-01) A simultaneous synthesis of white poly(dibromophenylene oxide) (P) or yellow radical ion polymer (RIP) and black conducting polymer (CP) were achieved from potassium 2,4,6-tribromophenolate by microwave energy in a very short time. Polymerizations were carried out (i) under constant microwave energy and constant amount of water with different time intervals ranging from I to 7 min or (ii) at constant time intervals and constant amount of water with variation of microwave energy ranging from 70 to 900 watt o...
Microwave-assisted simultaneous synthesis of conducting, non-conducting and cross-linked polymers from sodium 2,4,6-tribromophenolate and LiOH Celik, Gueler Bayrakli; Kisakuerek, Duygu (Informa UK Limited, 2007-01-01) Poly(dibromophenylene oxide) (P) and conducting polymer (CP) and/or cross-linked polymer (CLP) were synthesized simultaneously from sodium 2,4,6-tribromophenol ate and LiOH by microwave energy in a very short time interval. Polymerizations were carried out (i) under constant microwave energy and constant amount of water with different time intervals ranging from I to 20 min, or (ii) at constant time intervals and constant amount of water with variation of microwave energy ranging from 90 to 900 W, or (iii) ...
