Chapter 3 – Safety and ethics of nanotechnology
Asmatulu, Ramazan; Zhang, Bangwei; Asmatulu, Eylem (Elsevier, 2013)Nanotechnology is one of the ways of improving many properties of materials, including physical, chemical, physicochemical, and biological, which can be useful for various applications in biomedical, textile, aerospace, ... -
Fabrication and assessment of a thin flexible surface coating made of pristine graphene for lightning strike protection
Zhang, Bangwei; Soltani, Seyed A.; Le, Louie N.; Asmatulu, Ramazan (Elsevier B.V., 2017-02)A thin flexible coating made of pristine graphene was fabricated and applied on the surface of a commercial carbon fiber epoxy prepreg laminate to protect it against the lightning strike. To assess the coating's effectiveness, ... -
A ferrofluid guided system for the rapid separation of the non-magnetic particles in a microfluidic device
Asmatulu, Ramazan; Zhang, Bangwei; Nuraje, Nurxat (American Scientific Publishers, 2010-10)A microfluidic device was fabricated via UV lithography technique to separate non-magnetic fluoresbrite carboxy microspheres (approximately 4.5 microm) in the pH 7 ferrofluids made of magnetite nanoparticles (approximately ... -
Galvanic corrosion of Al/Cu meshes with carbon fibers and graphene and ITO-based nanocomposite coatings as alternative approaches for lightning strikes
Zhang, Bangwei; Patlolla, Vamsidhar Reddy; Chiao, D.; Kalla, Devi Kiran; Misak, Heath Edward; Asmatulu, Ramazan (SPRINGER LONDON LTD, 2013-07)Earlier airplane fuselages were made primarily of aluminum alloy sheets, which have very good electrical conductivity. If lightning strikes an aluminum alloy surface, the current generated by the lightning can easily flow ... -
Guiding nonmagnetic particles by external magnetic field in a microfluidic device
Zhang, Bangwei (Wichita State University, 2008-12)This report presents the fabrication of a micro fluidic device using the UV lithography method in order to separate nonmagnetic fluoresbrite carboxy microspheres from the mixed ferrofluids in microchannels. The microfluidic ... -
