Article Citation - WoS: 70Citation - Scopus: 76Humidity-Sensing Properties of a Zno Nanowire Film as Measured With a Qcm(Elsevier Ltd., 2011) Erol, Ayşe; Okur, Salih; Yağmurcukardeş, Nesli; Arıkan, M. ÇetinThe humidity-sensing properties of ZnO nanowires synthesized by carbothermal catalyst-free vapor solid (VS) technique were studied. The morphology and the crystal structure were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The humidity adsorption and desorption kinetics of the synthesized ZnO nanowires were investigated via quartz crystal microbalance (QCM) measurements. The observed positive frequency shift of ZnO nanowires when loaded on the QCM crystal under varying relative humidity conditions can be explained in terms of visco-elastic variations in their mechanical stiffness.Article Citation - WoS: 5Citation - Scopus: 6New Approach for Consideration of Adsorption/Desorption Data(Elsevier Ltd., 2011) Baleanu, Mihaela Cristina; Nigmatullin, Raoul R.; Okur, Salih; Ocakoğlu, KasımIn this paper we proposed a new approach to modify the Langmuir model by considering nonlinear effects such as diffusion of water molecules in/out of an adsorbing film for humidity adsorption and desorption kinetics. The model was tested on the humidity adsorption and desorption data of a spin coated 50. nm thick Ruthenium polypridyl complex (Ru-PC K314) film, measured under relative humidity between 11% and 97% using by Quartz Crystal Microbalance (QCM) technique. © 2011 Elsevier B.V.Conference Object Citation - WoS: 6Citation - Scopus: 11Odor Adsorption Kinetics on Modified Textile Materials Using Quartz Microbalance Technique(Polish Academy of Sciences, 2012) Sarıışık, Merih; Okur, Salih; Asma, Ş.In this study, a functional product with aromatic oil and vitamins for use at aromatherapy and spa centers or personal care has been designed to improve life quality of users by using multifunctional products with good odor, moisturizing, relaxation, anti-aging effects. For this purpose, commercial berry berry oil was capsulated in β-cyclodextrin, and then applied to 100% cotton towel fabric. Quartz crystal microbalance sensors were used to investigate odor adsorption kinetics on modified textile materials for the first time. The frequency responses vs. time plot shows clear linear step responses to the change in the concentration of odor molecules coming from the container filled with berry berry applied textile. The results also reveal that TiO 2 coated quartz crystal microbalance sensors can be used as e-nose to sense odor from textile coated with berry berry oil containing β-cyclodextrin capsules.
