< Taken by Jessica: Where is the conference site? >

Seok-Woo participated in the STEM day at Farmington, CT on March 10^th, 2018. East Farm Elementary School and Farmington Continuing Study organized this special event at Farmington High School, and about 50 elementary school kids (from the 1st grade to 6th grade) attended with their parents. UConn Jackson Laboratories, Connecticut Children’s Medical Center, Connecticut Department of Energy and Environmental Protection, and Farmington High School Robotics Team participated in this event, too.

As a materials scientist, Seok-Woo gave fun lectures regarding “Who is a scientist?” and “What is inside the materials we see in our every lives?” He ran the hands-on practice, “how to build crystal structures”, with kids and parents. They built simple cubic, body-centered-cubic, face-centered-cubic and graphene structures by using the modeling magic clays and wood sticks. He also demonstrated how to make bubble crystals and how they react to the force. You can find some useful movies at his website, too (https://swlee.engr.uconn.edu/bubble-raft/).

Seok-Woo learned that making the body-centered cubic structure with kids is really fun because many young kids have a trouble to put the atom in the middle of cubic structure.

 

Gyuho and Jessica attended the UConn SOE poster competition on 03/09/2018.

The title of Gyuho’s poster is “Superelastic superconductor, CaKFe4As4.”

The title of Jessica’s poster is “Microstructural Characterization and Micropillar Fabrication of Amorphous Boron.”

       

Gyuho’s work on YCd6 quasicrystal approximant was published at Journal of Materials Science! Many congratulations! He studied the size effect on mechanical behavior of YCd6 quasicrystal approximant, and compared it with icosahedra Y-Cd quasicrystal. The importance of translational symmetry on mechanical properties were investigated. The publication information is shown below.

Seok-Woo receives the teaching excellence letter for his MSE4004 lecture in 2017 Fall semester.

Seok-Woo receives 2018 Scholarship Facilitation Funds from UConn Office of vice president research.

Hetal has worked as an undergraduate researcher in our laboratory since her freshmen year. She has studied mechanical behaviors of various metals and intermetallic compounds using nanoindentation. She finally receives UConn University Scholar Award for her proposal entitled “Cryogenic Dislocation Nucleation Study on Body-Centered Cubic Metals by Using Spherical Nanoindentation.” This is a great honor for her as well as our MSE department! I believe there has been no University Scholar in our department before (Only 30 students are selected each year in the entire UConn undergraduate students). We are very proud of your great achievement! Hetal will work in our laboratory for three semesters as University Scholar! The list of 2018 UScholar is available here.

 

UConn University Scholar

The University Scholar Program is one of the most prestigious programs for undergraduates at the University of Connecticut. Available to students from all of the University’s schools and colleges, the University Scholar Program allows students to design and pursue an in-depth research or creative project and to craft an individualized plan of study that supports their intellectual interests during their final three semesters. Each student is mentored by an advisory committee of three faculty.

No more than 30 University Scholars are selected each year. Admission is based on an application submitted during the first semester of a student’s junior year. Applications are reviewed by an interdisciplinary faculty committee that looks for innovative projects and academically rigorous course selection. Graduation as a University Scholar recognizes a student’s exceptional engagement in research and/or creative endeavors.

University Scholars have created toys to help autistic children learn, produced advances in stem cell research, invented processes for running campus buses on cooking oil, written travel and mystery novels, and much more.

Seok-Woo receives MSE Teaching Excellence of the year!

This award recognizes outstanding teaching according to undergraduate MSE student surveys.

 

Keith’s recent publication in Nano Letters is featured at Brookhaven National Laboratory News.

Also, this work is featured at Brookhaven National Laboratory Main Webpage! (on 12/12/2017) (See below).

Congratulations!

Gyuho received the 2018 GE fellowship for his work on superelastic superconductor CaKFe4As4!!! The second GE fellowship after Keith’s one!

Many congratulations!!!
