When U of L chemistry researcher Dr. Paul Hayes sees a cornfield, he looks much deeper than the rows, the stalks or even the kernels.

He envisions matter at the molecular level and sees corn as a source for biodegradable material, such as a plastic drinking cup, rather than just a common vegetable.

In fact, Hayes looks at many common materials and thinks up ways to improve them at the molecular level by making them more useful, energy efficient and, like biodegradable corn-based drinking cups, more environmentally friendly.

His award-winning research focuses on synthetic chemistry, or the making of molecules. More specifically, he prepares new molecules – called catalysts – that are able to convert one chemical into another without themselves being consumed or altered.

Chemistry researcher Dr. Paul Hayes takes his lab to the cornfield.

One of his recent projects focuses on the challenge of making new materials that are both biodegradable and biocompatible.

"We prepare catalysts that convert a chemical found in corn or beets into a plastic-like material called polylactide," explains Hayes. "Polylactide can be made into a wide variety of manufactured goods, such as drinking cups or other biodegradable products. We can either shorten or extend the biodegradable lifespan of the product based on how we fine-tune the molecular structure of the polylactide."

The ability to manipulate these characteristics opens up possibilities for many new and useful materials in the future.

For example, Hayes explains packaging materials can have readily adjusted biodegradation rates to accommodate the need for various shelf lives of different items, providing an alternative "green" plastic for food packaging.

Hayes' research also has medical applications like absorbable sutures, matrices for the slow release of pharmaceuticals and polymer scaffolds for tissue engineering.

Hayes, who has been at the U of L for four years, continues to develop his thriving independent research program, which has produced numerous publications in top-tier journals and received more than $1.4 million in funding from provincial and national agencies, such as the Natural Sciences and Engineering Research Council of Canada, Canada Foundation for Innovation, Canada School of Energy and Environment and GreenCentre Canada.

As a result of these successes the young researcher has earned province-wide accolades, including the prestigious Alberta Ingenuity New Faculty Award. Most recently, Hayes accepted a Distinguished Academic Early Career Award from the Confederation of Alberta Faculty Associations for his ongoing accomplishments and future research potential.

It's a promising future for all Albertans, really, thanks to leading ��Ѹ��Դ��߿�Ƭ like Hayes, who just happens to be tackling world issues at the molecular level.

The Confederation of Alberta Faculty Associations (CAFA), the provincial organization representing academic staff associations at the ��Ѹ��Դ��߿�Ƭ of Alberta, the ��Ѹ��Դ��߿�Ƭ of Lethbridge, and Athabasca ��Ѹ��Դ��߿�Ƭ, recently announced the recipients of the CAFA Distinguished Academic Awards for 2010.

Among the recipients is Dr. Paul Hayes an Associate Professor in the Department of Chemistry and Biochemistry, who will receive the 2010 CAFA Distinguished Academic Early Career Award at an event in mid-September.

The CAFA Distinguished Academic Early Career Award recognizes academic staff members who, at an early stage of their careers, through their research and/or other scholarly, creative or professional activities, have made an outstanding contribution to the wider community beyond the university.

Hayes is being recognized for, among other projects, his research to find a cost-effective, environmentally sustainable 'green' alternative to conventional plastics.

Building his research programme at the ��Ѹ��Դ��߿�Ƭ of Lethbridge from scratch, Hayes has been able to attract top-quality students and postdoctoral fellows to his lab. As principal investigator, he has secured multi-year external funding, including grants from the Canada Foundation for Innovation (CFI), Alberta Ingenuity, NSERC, the Canada School of Energy and Environment, and GreenCentre Canada.

Hayes' research is receiving wide attention in the scientific community, and already has resulted in an impressive string of high-profile publications in leading peer-reviewed chemistry journals, in addition to numerous invited presentations at scholarly conferences across Canada and abroad.

His research in the field of organometallic chemistry, focusing on fundamental questions in catalysis and polymer science, addresses the need to develop new technologies for chemical conversions, which are crucial to drug development, materials synthesis, and the production of value-added chemicals.

Specifically, his work on polylactide polymerization catalysis advances our understanding of the synthesis of 'green' polymers, that is, biodegradable polymers that can be prepared from inexpensive renewable sources, such as corn.

This research holds the key to the challenge of producing viable alternatives to many conventional materials, such as 'green' plastic for food packaging. Lactone polymers also have many possible medical applications, for example in absorbable sutures, matrices for the slow release of pharmaceuticals, and polymer scaffolds for tissue engineering.
