Synthesizing Pure Graphene, a ‘Miracle Material’

Formed deep within the earth, stronger than steel, and thinner than a human hair. These comparisons aren’t describing a new super hero. They’re describing graphene, a substance that some experts have called “the most amazing and versatile” known to mankind.

UConn chemistry professor Doug Adamson, a member of the Polymer Program in UConn’s Institute of Materials Science, has patented a one-of-a-kind process for exfoliating this wonder material in its pure (unoxidized) form, as well as manufacturing innovative graphene nanocomposites that have potential uses in a variety of applications.

UConn Chemistry REU Symposium 2017

The Research Experience for Undergraduates (REU) Program, funded via the National Science Foundation, allows undergraduate students the opportunity to spend their summer conducting research at a REU host institution. Students spend approximately 10 weeks working closely on a research project with faculty members and graduate students. Students will also have the opportunity to utilize the research equipment and facilities specific to the host site.

To culminate their experience, the REU participants in chemistry presented their summer-long projects in a symposium on August 2, 2017. Click through the slideshow below to get a taste of what they accomplished!

 

Dr. Rebecca Quardokus Shares Her Passion For Microscopy

By Amanda Campanaro, IMS

There’s a special moment for most students when they discover what they really want to do with their major. For Rebecca Quardokus, Assistant Professor in Chemistry and associate faculty in IMS, that moment came as a junior at Grand Valley State University, Michigan, when her father sent her an article on Professor James Tour’s research at Rice University, Texas.

Dr. Quardokus, who had recently become a chemistry major, found the research fascinating. “His group had synthesized nano-sized cars with C60 fullerenes (buckyballs) for wheels, and they used scanning tunneling microscopy (STM) to image individual cars moving around on a gold surface,” Dr. Quardokus explains. “I was very excited to learn that STM, in addition to imaging, could manipulate individual atoms and molecules on the surface.” It was then she decided to attend graduate school to work with and master that “amazing technique.”

Now, Dr. Quardokus focuses her research on the engineering and reliability of molecular networks and two-dimensional materials for next-generation electronic devices. Her passion for learning STM has led her to begin a project working on developing new two-dimensional materials using surface-confined polymerization reactions.

“I use scanning tunneling microscopy, with its ability to measure individual atoms and molecules, to study the reactants and products,” she says.  “I will also study the charge and thermal transport properties of these materials.” Her group is hoping to tune specific properties for use in next-generation electronics.

From Storrs to Shanghai, Chemistry Professor Aims to Bridge International Collaboration

By Amanda Campanaro, IMS

Yao Lin, Associate Professor of Chemistry in the Polymer Program of the Institute of Materials Science, has become very passionate about chemistry and polymer science—and about encouraging intercontinental collaboration on it. With a background in chemistry, polymer and molecular biology and a degree from Fudan University, China, Dr. Lin is interested in researching bio-inspired materials for the future and developing educational opportunities for students at home and abroad.

Dr. Lin and his lab are currently working on two projects which mimic certain natural protein polymers and complex enzymes to create synthetic, bio-inspired materials. One direction is trying to understand the cooperative folding and interactions between complex macromolecules containing synthetic polypeptides to mimic the dynamic process of protein polymerization. According to Dr. Lin, the protein polymerizations provide the filaments with excellent mechanical strengths for our muscles, our cells, and contribute to cell movement. The reason cells can move is partially because these protein fibers can grow on one end, and shrink on the other end.

The other direction involves mimicking an enzymatic structure that forms “teams” that can degrade cellulose into sugars. When bacteria develop complex structures like nano-machines that recruit six to ten different types of enzymes into a team, they can work much more effectively than individual enzymes. Dr. Lin and his group are researching whether they can replace that type of protein scaffold with synthetic polymers, and thus design the chemistry at interface between these polymers and proteins. This will allow them to recruit different engineered proteins in an organized manner.
