Physicochemical and structural characterization of microfluidized and sonicated legume starches
Bitik, Ayşe; Şümnü, Servet Gülüm; Department of Food Engineering (2019)
Modified starches gained importance in food industry due to their improved functional properties. In this study, two legume starches (chickpea and lentil) were modified by using ultrasonication and microfluidization techniques. The objective of the study was to investigate the effects of these methods on the functional, rheological, thermal properties and particle size, morphology and crystal structure of modified starch samples. Time Domain NMR relaxometry experiments were also conducted to understand the ...
Antibacterial properties and osteoblast interactions of microfluidically synhtesized chitosan – spion composite nanoparticles under external static magnetic field
Kafalı, Melisa; Ercan, Batur; Erdem, Emine Yegan; Department of Metallurgical and Materials Engineering (2022-8-18)
In this research, a multistep microfluidic reactor was used to fabricate chitosan superparamagnetic iron oxide composite nanoparticles (Ch - SPIONs) to develop antibacterial agents that can be targeted to infection foci and visualized with magnetic resonance imaging. Monodispersed Ch – SPIONs had an average particle size of 8.8 ± 1.2 nm with a magnetization value of 32.0 emu/g. These nanoparticles were used to fight against Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa), which ...
Design and implementation of reconfigurable transmitarray unit cells employing the element rotation method by microfluidics
Erdil, Emre; Aydın Çivi, Hatice Özlem; Topallı, Kağan; Department of Electrical and Electronics Engineering (2014)
This thesis presents design, fabrication and measurement of a novel, continuously tunable, circularly polarized X-band microfluidic transmitarray unit cell. To the author’s knowledge, this is the first study in the literature where a microfluidics approach is used to tune the phase of the transmitted field through the unit cell by the element rotation method. Furthermore, the generalized transmitarray design conditions necessary to utilize the element rotation method are derived. To implement the novel micr...
Application of image enhancement algorithms to improve the visibility and classification of microcalcifications in mammograms
Akbay, Cansu; Gençer, Nevzat Güneri; Gençer, Gülay; Department of Biomedical Engineering (2015)
Breast cancer is the second leading cause of cancer deaths for women. Mammography is the most effective technology presently available for breast cancer screening, despite the fact that there are still some limitations of the imaging technique, such as insufficient resolution, low local contrast and noise combined with the subtle nature of the usual radiographic findings. One of the most important radiographic findings associated to the existence of breast cancer is the clustered microcalcifications. Especi...
