Welcome New Undergraduate Researchers

January 2018

The Davis Research Group is pleased to welcome several new undergraduate researchers!

Tara Goldberg (Sophomore in Materials Science and Engineering) will be working with Naomi on fluorescent dye functionalization of surfaces.

Michael Klingseisen (Sophomore in Materials Science and Engineering) will be working with Amin on LabView coding.

Nolan Miller (Sophomore in Materials Science and Engineering) will be working with Mitchell and Hyeyoung on thin film buckling mechanics.

If you are interested in performing independent undergraduate research (MSE 499) in our group, please contact Dr. Davis.


Hyeyoung Successfully Defended her Prelim

October 2, 2017

Hyeyoung is now officially a Ph.D. candidate after presenting her preliminary research results and successfully defending her work to the committee.

 Utilizing the wrinkle-to-delamination transition, Hyeyoung is measuring the adhesion of thin films on compliant substrates

Interfacial Mechanophore in Silk-Epoxy Composites Article Published

May 22, 2017

Work conducted by researchers (including Dr. Davis) at the National Institute of Standards and Technology (NIST) recently appeared in the journal Advanced Materials Interfaces. This research focused on the installation of a mechanically-activated fluorescent probe molecule at the interface of a fiber/polymer composite. Upon deformation of a single fiber tensile specimen, the fluorescent intensity of the mechanophore increased, indicating the transfer of stress across the composite interface. The technique can be generalized to a host of industrially-relevant materials systems, leading to self-reporting interfacial damage sensors in bulk fiber reinforced composite systems.
