She developed a novel rheological protocol, called serial creep divergence, to characterize the time-dependent evolution of structure and properties in thixotropic yield stress fluids. This approach enables the first clear quantification of yield stress in these specific complex materials for prototypes that require flexibility, elasticity, and shock absorption and eliminate expensive or time consuming custom molds. <\/p>\n\n\n\n<p>By adjusting how quickly a material rebuilds its internal structure after being pushed or mixed, they could create gels that flow easily through a printer nozzle but then solidify almost immediately once deposited. If a material is too runny or too stiff, it simply won\u2019t print well. But by precisely controlling its properties temporarily the material can produce stable, well-defined shapes from soft, gel-like materials.<\/p>\n\n\n\n<p>\u201cOne of my favorite memories in the lab was when our custom-built 3D printer produced its first successful print,\u201d said Nikoumanesh. \u201cIt took months of hard work and teamwork, and seeing it finally come together was incredible. In our group, I worked with our undergraduate students to set up the printer and develop printing protocols that bridge our fundamental discoveries about thixotropy with practical 3D printing of soft materials.\u201d<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"597\" height=\"1024\" src=\"https:\/\/web.uri.edu\/engineering\/wp-content\/uploads\/sites\/2168\/6-597x1024.jpg\" alt=\"\" class=\"wp-image-87191\" style=\"width:375px;height:auto\" srcset=\"https:\/\/web.uri.edu\/engineering\/wp-content\/uploads\/sites\/2168\/6-597x1024.jpg 597w, https:\/\/web.uri.edu\/engineering\/wp-content\/uploads\/sites\/2168\/6-175x300.jpg 175w, https:\/\/web.uri.edu\/engineering\/wp-content\/uploads\/sites\/2168\/6-364x625.jpg 364w, https:\/\/web.uri.edu\/engineering\/wp-content\/uploads\/sites\/2168\/6-500x858.jpg 500w, https:\/\/web.uri.edu\/engineering\/wp-content\/uploads\/sites\/2168\/6.jpg 746w\" sizes=\"auto, (max-width: 597px) 100vw, 597px\" \/><figcaption class=\"wp-element-caption\">The framed cover of Soft Matter that featured her paper, gifted to her by her advisor<\/figcaption><\/figure>\n<\/div>\n\n\n<p>During her time at URI, she has had three papers published in multiple leading journals. <em>Soft Matter<\/em> even featured her paper, \u201cElucidating the Role of Physicochemical Interactions on Gel Rheology\u201d on the journal\u2019s cover. \u201cPublishing my first paper was another unforgettable moment,\u201d said Nikoumanesh. \u201cI also really enjoyed mentoring undergraduate students and watching them grow as researchers.
