Before coming to UConn, Hanyi completed a bachelor’s degree in macromolecular materials & engineering in Taiyuan University of Technology, then a master’s degree in polymer chemistry & physics at Zhejiang University. After this experience, Hanyi joined the UConn IMS Polymer Science Ph.D. Program with great drive and enthusiasm.  Under the guidance of co-advisors, Professors Jie He and Yao Lin, Hanyi’s research resulted in an astounding ten publications as lead author and eighteen as co-author.  This extensive publication list has already led to 641 citations.

In 2023 Hanyi received the Samuel J. Huang Graduate Student Research Award for his outstanding performance.  His thesis, “Plasmonic Patchy Nanoparticles: Controlled Synthesis and Self-Assembly in Solution,” was completed in summer 2024.

Hanyi has taken a position as postdoctoral research scholar at Indiana Univ., Bloomington. He is blazing the trail to his long- term goal: a faculty research position.

IMS Polymer Program Welcomes New Students

IMS Polymer Program fall 2024 semester new students
Clay Gensel (l) and Vinh Le (r) joined the IMS Polymer Program Ph.D. program for the Fall 2024 semester.

The IMS Polymer Ph.D. Program welcomes two students this fall, Clay Gensel and Vinh Le.  Both are local New Englanders.  Clay Gensel completed his bachelor’s degree in chemistry at UMass Amherst in the spring of 2024.  During his senior year there, he joined the research lab of Professor Bryan Coughlin. This experience gave him both the desire to pursue a doctoral degree program and the confidence to do so.  Intrigued with the polymer research in the Coughlin lab, Clay decided to pursue the UConn Polymer Program

Vinh Le completed his bachelor’s degree in chemistry at Central Connecticut State University. During his program he was introduced to organic synthesis in the research lab of Professor Neil Glagovich. After completing his degree, Vinh gained 3 years of professional experience in local industry. This experience introduced him to the exciting world of polymer science. Vinh was eager to join the UConn Polymer Program because it gave him the unique opportunity to study polymer science while living in his home state of Connecticut.

The polymer program welcomes these two talented Ph.D. students.

Dr. Tianjian Yang

With a continued curiosity in the materials he encountered during his childhood, Tianjian Yang wanted to satisfy his interest at a higher level. When studying Materials Science as an undergraduate at Jinan University, Tianjian discovered polymers. This led him to join the research lab of Prof. Ziyang Zhang where he became deeply involved with the research and completed his first scientific paper. Hungry for more knowledge, Tianjian joined the Materials Science and Engineering master’s degree program at the University of California, San Diego. This experience introduced him to synthetic chemistry used in biology.  Upon discovery of Prof. Yao Lin’s research in polypeptides for biomedical applications, Tianjian joined the UConn Polymer Program.

Tianjian’s hard work and talent was recognized. He published three papers as lead author, has two more in process, and was co-listed on numerous more.  He was a finalist for the national 2024 Eastman Chemical Student Award. He also received the UConn Polymer Program 2024 Samuel J. Huang Graduate Student Research Award.

Tianjian said he loved IMS because of the variety of research projects, the extensive access to instrumentation, the collaborative nature of the community, and the faculty’s willingness to help all students with questions. He said this was the perfect program for his interests and goals.

This summer he successfully defended his thesis: “Biomimetic Supramolecular Materials Assembled from Synthetic Polypeptides”. This month he started a position as a postdoctoral research scholar at Johns Hopkins University. Tianjian’s long-term goal is to become a professor.

Mu-Ping Nieh Named Director of IMS Polymer Program

After three years as director of the IMS Polymer Program, Dr. Kelly Burke has stepped down to assume the role of Head of the Department of Chemical & Biomolecular Engineering. Faculty members have elected Professor Mu-Ping Nieh as the new director of the IMS Polymer Program.

Professor Nieh’s first achievement as director was writing a successful Graduate Assistance in Areas of National Need (GAANN) grant proposal. The Department of Education-backed grant will provide over $1 million to support domestic students over three years.  Additional goals include increasing student recruitment, creating new courses, and coordinating a polymer certificate program consisting of a series of short courses.

The program plans to create new polymer courses as an option for the science and technology requirement for undergraduate general education courses.  These courses will introduce students to polymer science, discuss the current plastic crisis, and analyze efforts to produce plastics that are environmentally friendly.

The goal of the planned polymer certificate program will be to provide advanced educational options for scientists and strengthen industrial ties. This task had been initiated in the past but was put on hold because of the COVID-19 pandemic in 2020. Dr. Nieh will continue the project with a proposed start date of Fall 2025.

The IMS Polymer Program welcomes the new leadership of Professor Nieh.

 The IMS Industrial Affiliates Program (IAP) 2024 Annual Meeting once again included a joint student poster session with IMS Polymer Program and Department of Materials Science and Engineering students sharing their research. 33 graduate students participated. The poster session provides an opportunity for students to interact with IAP members and industry partners, many of whom have hired our graduates in the past. The Program presented its annual Poster Awards at the 202 poster session.

 

Rumesha Pererage, from the Adamson Research Group, received third place prize for her poster, “Graphene polyamide membrane for in situ electrochemical CO2 reduction”.

 

Huijie Li, from the Zhang Research Group, received second place prize for their poster, “Microneedle-based potentiometric sensing system for continuous monitoring of nutrients in skin interstitial fluids”.

 

Yasmin Bimbatti, from the McCutcheon Research Group, received first place honors for her poster, “Thin Film Composite Ion Exchange Membranes by Electrospray”.

Collaborative Research to Develop Filament-Based Hydrogels is Cover for JACS

Posted on by

Yao Lin JACS cover imageIn a collaborative effort, researchers from the University of Connecticut (led by Profs. Yao Lin, VJ Kumar and Xudong Yao) and the University of Illinois at Urbana-Champaign (led by Prof. Jianjun Cheng) have made an advance in the rational design of synthetic polypeptides to develop filament-based hydrogels. The work, conceptualized and realized by the graduate students Tianjian Yang (UConn) and Tianrui Xue (UIUC), has been published in the Journal of the American Chemical Society (JACS) and featured as the cover of the March 6 issue.

Building on the recent advancement of autoaccelerated ring-opening polymerization of amino acid N-carboxyanhydrides (NCAs), this study strategically explores a series of random copolymers comprising multiple amino acids, aiming to elucidate the core principles governing gelation pathways of these purpose-designed copolypeptides. The team found that the selection of amino acids steered both the morphology of fibril superstructures and their assembly kinetics, subsequently determining their potential to form sample-spanning networks. Importantly, the viscoelastic properties of the resulting supramolecular hydrogels can be tailored according to the specific copolypeptide composition through modulations in filament densities and lengths. The findings enhance our understanding of directed self-assembly in high molecular weight synthetic copolypeptides, offering valuable insights for the development of synthetic fibrous networks and biomimetic supramolecular materials with custom-designed properties.

The research was supported by NSF grants awarded to Yao Lin at UConn (DMR 1809497 and 2210590) and Jianjun Cheng at UIUC (CHE 1905097).
