Conference Object Citation - WoS: 1Design Study of a Medical Device(Institute of Electrical and Electronics Engineers Inc., 2017) Taşkın, Burcu; Başoğlu, Ahmet Nuri; Başoğlu, Ahmet Nuri; 02.04. Department of Industrial Design; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyFor the new product design in the medical industry, the designer's role is to identify requirements of product by focusing on the target need, demand and market supply. This research aims to explore the main problems of existing crutches in the medical industry with two phases; to identify the crutch design requirements by research and to define market position involving financial analysis with three economic scenarios. Therefore, the study based on a research with reutilize multiple techniques for walking aid design requirements through needs and demands, aims to discuss the collected data from different perspectives of medical experts, medical store owners and crutch users to create design criteria.Article Citation - WoS: 5Citation - Scopus: 5Methylene Blue Adsorption From Aqueous Solutions To Flexible Poly(vinyl Chloride) Silica Composites(John Wiley and Sons Inc., 2015) Yetgin, Senem; Ulutan, Sevgi; Balköse, Devrim; 03.02. Department of Chemical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyMethylene blue (MB) adsorption studies were performed with poly(vinyl chloride)-(dioctyl phthalate)-silica composites, which were obtained by using plastisol-plastigel technology. The films were flexible, having elastic modulus of 1.0-1.5 GPa. Diminishing MB concentration in the aqueous phase was followed as the adsorption process advanced by using visible spectroscopy. Contributions of the individual components of the composites to adsorption were also investigated. Although the MB adsorption capacity was extensively high for silica, it was moderate for the composite, most likely owing to the occlusion of pores of silica by plasticizer to some extent. The improvement of MB adsorption capacity of the composites as the silica ratio increased was explicitly deduced from the optical microscopy photographs. The diffusion coefficients of MB through the composites were 5 × 10-13, 6 × 10-13, and 3 × 10-13 m2 s-1 with regression coefficients of 0.73, 0.89, and 0.88 for 0, 2, and 16% silica-containing composites, respectively. Because of the slow diffusion of MB in poly(vinyl chloride)-silica composites, using them as dynamic column adsorbent was not practical. However, these versatile plastics can be used as plastic labels, colored clothing, leather substitutes, antimicrobial medical devices, and laser printable surfaces.
