This goal would be achieved through the development of a millifluidic\ncell which would help us simulate the environmental conditions that a typical\ncan coating is exposed to. In addition to that, a series of experiments\nsimulating the degradation of these coatings will be conducted to understand\nthe mechanisms that govern the infamous epoxy\/phenolic system deterioration. A\nparticular focus towards the adhesion mechanisms involved in the epoxy\/phenolic\nsystems with a range of substrates will be given to understand the origins of\nthe excellent dry coating adhesion. Electrochemical experiments will be\nconducted to mimic the corrosion process of the coatings subject to different\nconditions and correlate it to adhesion energies of the coating\/substrate\nsystem.&nbsp; <\/p>\n\n\n\n<p><strong>Research Focus II:<\/strong><\/p>\n\n\n\n<p>I am also investigating the development of bio-composite\nfilms for packaging applications as potential replacement for fossil fuels\nbased synthetic films. The limitations of conventional biopolymer films lie mainly\nin water absorption and mechanical fragility. I am trying to overcome these\nlimitations by incorporating soft microparticles (recently discovered by our\ngroup) made of environmentally benign polymers as mechanical reinforcement for\nthose films. Preliminary results show a good promise that the composite films\nare mechanically robust and have excellent optical properties.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ymkotb@ncsu.edu M.S., Chemical Engineering, 2017Cairo University B.S., Petrochemical Engineering, 2014Cairo University Research Focus I: My research focuses on the fundamental understanding of the excellent mechanical&#8230;<\/p>\n","protected":false},"author":197,"featured_media":0,"parent":36,"menu_order":17,"comment_status":"closed","ping_status":"closed","template":"page-left.php","meta":{"_acf_changed":false,"first_name":[],"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"class_list":["post-1675","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/cbe.ncsu.edu\/velevgroup\/wp-json\/wp\/v2\/pages\/1675","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cbe.ncsu.edu\/velevgroup\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/cbe.ncsu.edu\/velevgroup\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/cbe.ncsu.edu\/velevgroup\/wp-json\/wp\/v2\/users\/197"}],"replies":[{"embeddable":true,"href":"https:\/\/cbe.ncsu.edu\/velevgroup\/wp-json\/wp\/v2\/comments?post=1675"}],"version-history":[{"count":3,"href":"https:\/\/cbe.ncsu.edu\/velevgroup\/wp-json\/wp\/v2\/pages\/1675\/revisions"}],"predecessor-version":[{"id":1679,"href":"https:\/\/cbe.ncsu.edu\/velevgroup\/wp-json\/wp\/v2\/pages\/1675\/revisions\/1679"}],"up":[{"embeddable":true,"href":"https:\/\/cbe.ncsu.edu\/velevgroup\/wp-json\/wp\/v2\/pages\/36"}],"wp:attachment":[{"href":"https:\/\/cbe.ncsu.edu\/velevgroup\/wp-json\/wp\/v2\/media?parent=1675"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
