Ames Laboratory, UConn Discover Superconductor with Bounce

The U.S. Department of Energy’s Ames Laboratory has discovered extreme “bounce,” or super-elastic shape-memory properties in a material that could be applied for use as an actuator in the harshest of conditions, such as outer space, and might be the first in a whole new class of shape memory materials.

Shape-memory materials “remember” their original shape and return to it after they are deformed. They are commonly metallic alloys that make possible “unbreakable” eyeglass frames and quieter jet engines.

But the material in this research, CaFe2As2, is not a metallic alloy but an intermetallic more well-known for its novel superconducting properties. It has been so extensively studied that the team of researchers, from Ames Laboratory and the University of Connecticut, also made note of its high degree of pressure and strain sensitivity, and wondered about its possibilities as a structural material.

The researchers created micropillars of the material through single crystal growth followed by focused ion beam milling, and then subjected them to mechanical compression testing. They found a recoverable strain that can exceed 13 percent.

UConn MSE Seniors Attend World Maker Faire For NASA Capstone Project

MSE Students at Maker Faire 2017

Francis Almonte, Zane Grady, Andrew Nguyen, Adam Wentworth, and Jason Santivanez (senior MSEs) attended maker faire to showcase last year’s NASA sponsored capstone project and introduce the extension of the project to the public.

UConn MSE students presented their projects related to additive manufacturing at the World Maker Faire in NY Hall of Science Queens, NY for the third consecutive year. The projects were part of a showcase called In Space 3D Printing and Recycling.

All MSE seniors took part in this exciting event, which involved students displaying a capstone project sponsored by NASA. This year’s showcase involved students displaying a capstone project previously sponsored by NASA. The project focuses on the recyclability of specific thermoplastics and will continue this academic year under new sponsorship from Tethers Unlimited Inc. (TUI). TUI is fabricating a new 3D printer and recycler that will eventually find its home on the International Space Station to begin testing in 2018.

UConn was among seven of the university teams chosen by NASA to “design systems, concepts, and technologies that will help improve NASA’s exploration capabilities”. This is all part of NASA’s sixth eXploration Systems Habituation Academic Innovation Challenge, which includes ideas to progress 3D printing abilities, develop plant growth systems, better spacecraft environmental recycling programs and create conceptual habitat designs.

“Polyelectrolytes in Multivalent Ionic Media: New Physics and New Materials”

Abstract
Multi-valent interactions in systems of polyelectrolytes can exhibit dramatic, non-monotonic effects, for example, switching forces from repulsive to attractive, and back to repulsive again, in some cases. We have been studying these patterns of behavior with the surface forces apparatus (SFA) and with electrochemical methods, such as cyclic voltametry, which enables the quantitative determination of the number of multi-valent ions residing in thin layers of charged polymers. At fixed ionic strength, all cause strong shrinkage and condensation of poly(styrene sulfonate) brushes over a narrow range of ratio multi-valent to mono-valent ions. When the multi-valent ion is an oppositely charged polymer, new fluid phases can form. Charged blocks in copolymers leads to materials with new types of ordered phases. Effects of these multi-valent interactions on supermolecular and biomolecular assembly will be discussed. There are many possibilities for the creation of new materials based on electrostatic assembly involving multi-valent interactions.

UConn Launches Chapter of National Academy of Inventors

Founding Members of UConn Chapter of National Academy of Inventors

Founding Members of UConn Chapter of National Academy of Inventors

The University of Connecticut hosted the inaugural gathering for Connecticut’s first chapter of the National Academy of Inventors (NAI) at the Lyceum in Hartford on Sept. 29.

The UConn NAI chapter was established as a result of the efforts and prodigious invention history of three distinguished researchers at UConn who are NAI Fellows. To receive this distinction from NAI, a researcher must be named inventor on patent(s) issued by the United States Patent and Trademark Office (USPTO) and must be affiliated with a university, non-profit research institute, or other academic entity.

Dr. Cato T. Laurencin, president of the UConn Chapter of the National Academy of Inventors became the first UConn NAI Fellow in 2013. Laurencin is well known for his pioneering work in the field of regenerative engineering and is an elected member of both the National Academy of Engineering and the National Academy of Medicine, and recipient of the National Medal of Technology and Innovation and the Connecticut Medal of Technology. In 2015, Dr. Pramod K. Srivastava, who is recognized globally for his groundbreaking discoveries in cancer immunotherapy, was named an NAI Fellow. Dr. Lakshmi Nair was inducted in 2016. Her work in regenerative biomaterials to enhance tissue repair and regeneration has resulted in many novel and valuable discoveries. Read the full story from Innovation Partnership

Kimberly Post Retires After 30 Years at UConn

Ms. Kimberly Post

Ms. Kimberly Post

She has supported four directors of the Institute of Materials Science and seen countless students, faculty and staff members come and go. After 30 years of service to IMS and 35 years with the State of Connecticut, Kimberly Post, Assistant to the Director of IMS, retires today.

“It’s bittersweet,” Kim says of her time at UConn coming to an end. “I like my job.” But with the most recent union-negotiated contract she would stand to lose more by staying than leaving. “State employment used to be a feather in your cap but it’s not so much that any more,” she says.

Reflecting on the changes she has witnessed over her tenure at UConn, Kim notes that interpersonal relationships have become more formal over the years. But she relishes in the memories of the assistance she has been able to provide to students and faculty members especially, and to the IMS as a whole, noting that, “When you have people working 25, 35 years or more in IMS, it says that’s a good place to work.”

Looking ahead, Kim says that she is excited about starting a new chapter in her life. In the years that she has worked for UConn and the State of Connecticut she has had three children who have given her four grandchildren. While she looks forward to having more time for family, Kim sees an opportunity to bring the skills she has gained through her work in IMS to a new challenge.  “I’m looking forward to a new chapter in my life,” she says.

Asked what she would miss most about her time in at UConn and in IMS she responded, “The people, definitely the people.”

Everyone at IMS wishes Kimberly the best as she starts her new chapter.

UConn’s School of Engineering Announces UConn-ZEISS Partnership and Introduces New Microscopy Center

The UConn School of Engineering announced the launch of a new UConn-ZEISS Partnership with the opening of a new, state of the art laboratory, the Reverse Engineering, Fabrication, Inspection and Nondestructive Evaluation (REFINE) Lab. The event was attended by many members of the ZEISS leadership team, including President of ZEISS North America, James Sharp.

According to Sharp, working with a top research institution like UConn is part of the ZEISS tradition.

“It is deep in our roots at ZEISS to collaborate with scientists to improve our products. Over 150 years ago, Carl Zeiss and physicist Ernst Abbe partnered to achieve global success,” explained Sharp. “Since then, more than 20 Nobel Prize winners have relied on ZEISS microscopes to conduct their research. We know that this tradition will continue thanks to the UConn-ZEISS partnership and the REFINE Lab.” Read the full story from Technology Innovation Partnership
