A recently formed club at UT has provided students with an outlet to bring their ideas to life via a mix of traditional and cutting-edge manufacturing methods.

The Makers Club began last semester with the goal of bringing together students and faculty interested in the makers movement, a group united by the idea of people learning and maintaining practical skills that were once common but are now in danger of being lost—such as welding—and to developing skills in cutting-edge techniques such as 3D printing.

The Makers Club focus on turning ideas into reality is attracting students from various majors across campus.

“It started because of an idea we had in class,” said Chase Cumbelich, a junior from Ooltewah, Tennessee, majoring in electrical engineering, who helped found the club. “We kept hitting a wall while we were trying to develop something, and we realized our lack of contact and knowledge with other majors was really hampering us.

“We reached out across the college and got about 30 people interested, and the club just kind of snowballed from there.”

Now that club is changing the life of a classmate.

One of the first things the group was able to produce was a 3D-printed hand, developed with other engineering students.

At a group meeting, the question was raised whether anyone knew of someone who might be in need of such a hand.

Riley Toll, a freshman from Memphis in biomedical engineering, stood up and said, “Yeah . . . me.”

“I’d heard about the group and had a lot of interest,” said Toll. “Things like this are one of the reasons I was interested in engineering to begin with—to be able to help people and give back.

“Hopefully this brings some awareness to what can be accomplished through engineering.”

Chad Duty, associate professor of mechanical, aerospace, and biomedical engineering, introduced the idea of 3D-printed prosthetics to the Makers Club, stemming from an ongoing effort of a group called the Enable Community Foundation. The Enable group matches up patients across the world who are in need of prosthetic appendages with groups like the Makers Club that have access to 3D printers.

The two parties work together to get the prosthetic limb fitted to the specific size and needs of the patient, and it is delivered free of charge.

Duty pointed out that groups like Enable that bring people together for a common cause underscore the role of having a network of makers and the promise that such innovators hold.

“There are a lot of good things that can be accomplished when groups of people work together,” said Duty. “The sky is the limit.”

Million-Dollar Idea Helps Fulfill Tennessee Promise

 

A new program designed to help Tennessee’s community college students better navigate the transition to the University of Tennessee has gained $1 million in support and recognition from the National Science Foundation (NSF).

Following the establishment of the Tennessee Promise program, which provides two years of free community college to the state’s students, faculty members in UT’s Tickle College of Engineering met to come up with a plan to accommodate transfer students and position them for success in the college.

The team focused on the five-year graduation rate for engineering transfer students—71 percent, compared to 85 percent for traditional students who enter as freshmen.

“Transfer students face a unique set of challenges compared to traditional students,” said Materials Science and Engineering Professor David Keffer, leader on the project. “We sought to develop a program, based on input from many directions, to create an experience for transfer students which addresses well-identified academic and social obstacles to successful completion of their degree.”

From those meetings, TranSCEnD—Transfer Success Co-Design in Engineering Disciplines was born. The initial NSF grant lasts through 2022, when it will come up for renewal based on the plan’s success.

The team is working on a program that covers all five years of the students’ experience at both institutions. Chris Wetteland, a lecturer in materials science and engineering, is developing a summer research program to improve the transitional experience, while Rachel McCord, a faculty member in the college’s engineering fundamentals program, is developing methods to improve student success.

“These elements will maximize the benefit of the state’s investment in its future via Tennessee Promise,” said Keffer. “Once we demonstrate that the TranSCEnD program works here, we will share it with other institutions.”

TranSCEnD members considered other factors facing transfer students in comparison to traditional students who enter the program as freshmen. Among their findings, they learned that transfer students:

  • are almost twice as likely to be first-generation students
  • have more than double the unmet financial need of traditional students
  • face stresses over class sizes and communication with faculty
  • often find it challenging to become a part of peer groups, some of which have already worked together for two years

The goal is to increase support for transfer students to bring retention and graduation rates to a comparable level with those of traditional undergraduates.

The TranSCEnD team’s efforts now involve Tickle College of Engineering staff, researchers, and administration; UT’s admissions office; and faculty from Pellissippi State Community College. More than half of the students transferring into the college completed their associate’s degree at Pellissippi State.

The physical, optical, and radiation properties of these scintillators will be characterized, and the team will also investigate how detectors in selected geometries should be made. The organic scintillator study will increase knowledge and understanding aimed at improving the efficiency, energy resolution, and mechanical properties for gamma and neutron sensing.

The team will also research and develop advanced algorithms relevant to search, localization, source identification, 3D mapping, source tracking, and dynamic path planning with autonomous vehicles.

The grant contributes to the education of students at these two institutions through development of course materials and providing research opportunities in radiation detection. At present, senior and graduate student design teams in NE and EECS are engaged in engineering of drones made partly of plastic scintillators and associated algorithms that may be able to accomplish indoor RN search.

Funding of $1.05 million has been recently awarded for the next three years, and funding for two additional years is an option. The name of the new grant is “Investigation of DEtectors, Algorithms, and Systems (IDEAS) to Advance Autonomous Radiological/Nuclear Search.”

Big Orange Family Campaign

The Big Orange Family Campaign: February 5—March 2, 2018

During the Big Orange Family Campaign, from now through March 2, 2018, faculty and staff can make a big difference at UT.

Together, little increases in financial engagement can have a huge impact across campus on multiple levels. Last fiscal year, university employees raised over $1.1 million through the generosity of more than 2,400 employee donors.  The majority of these gifts were made at $100 or less. This support touched professorships, student scholarships, facilities improvements, research funding, and countless Volunteer lives.

In 2017, the Tickle College of Engineering achieved a record 58% college employee participation rate. Help us exceed expectation again this year. No matter the size, every gift to any UT fund counts toward participation. Through the cultivation of a culture of philanthropy at the university, we can make a Big Orange impact on campus.

A team of engineering students has been selected to participate in NASA’s Student Launch project, which pits 45 teams from across the country against one another in an attempt to overcome a specific challenge.

This year’s competition, held during rocket trials April 4–8 at NASA’s Marshall Space Flight Center in Huntsville, Alabama, requires teams to build a reusable rocket capable of carrying a payload at least one mile high and successfully landing back on Earth.

Teams have a choice of one of three payloads:

  • a camera that can identify and discern between targets in flight
  • a rover that deploys upon landing, moves at least five feet, and extends solar panels
  • an onboard system that can triangulate a landing within a specified zone

“We made a unanimous decision to go with the rover option,” said Grayson Hawkins, a senior in mechanical engineering who co-leads the team with Theresa Palandro, a senior in aerospace engineering. “We must consider problems such as ‘Can the main axle handle 20 Gs of acceleration?’ and ‘What is the most efficient way to stow the rover during flight?’”

This marks the first time UT is taking part in the 18-year-old competition. Other Southeastern Conference schools participating include Auburn University, the University of Florida, and Vanderbilt University.

More than 30 UT students have had interest in the project, with about a dozen in the core UT Rocketry Team.

While they are allowed to have faculty supervision, the students must do all of the work themselves.

“It is our hope that we are creating permanent roots, so that future students will have these and more opportunities,” said Hawkins.

The group is working under UT’s Student Space Technology Association—founded by Hawkins three years ago and part of the Center for Student Engagement—and has been supported by the Tickle College of Engineering.

Drawings of the rocket, details about their plans, and timelines are included in the team’s preliminary design review, located on their website.

Peer acknowledgment is often regarded as one of the best forms of recognition for researchers in any given field.

One Tickle College of Engineering faculty member has earned the distinction of being among the most cited researchers in the world, according to Clarivate Analytics, formerly Thompson Reuters.

Jerry and Kay Henry Endowed Professor of Materials Science and Engineering David Mandrus was recently recognized for their contributions to science.

“This is a tremendous honor,” said Mandrus. “Having other scientists acknowledge our contributions is a validation of the research we’ve been conducting.”

It’s the second such recognition for Mandrus since 2014. Clarivate Analytics studied research and releases, measuring the total number of times that others cited the material in their own findings.

Those measurements came in relation to specific findings and papers rather than a cross-examination of all work tied to a researcher, placing the two UT faculty members in the top 1 percent of all research scientists across the world.

Mandrus’s research involves discovering new materials related to electronics and magnetics, such as superconductors and thermoelectrics.

A Fellow of the American Physical Society, Mandrus has seen his research cited more than 6,000 times.
