Dow and Caltech's Resnick Institute Partner to Award Student Innovations in Sustainability

This Year's SISCA Award Recipients Include Scientists who are Developing New Ways to Protect the Earth from Harmful Chemical Waste

PASADENA, CA – NOVEMBER 18, 2013 – Nicole Peck and Zhan Wang have been awarded first place in this year's Sustainability Innovation Student Challenge Award (SISCA) competition at Caltech. The two scientists have engineered a new technology for clean chemistry that will save energy and lessen impact of leftover chemicals on the environment. The SISCA program was created and sponsored by Dow, with matching support for the Caltech prize from the Resnick Sustainability Institute.

Dr. Wang and Ms. Peck have used “biocatalysis,” a technique for development of enzymatic alternatives to traditional transition metal catalysis. This means that biological agents, which use less energy for processing and leave no harmful residue, can be used to speed reactions important in the production of commodity chemicals such as insecticides and pharmaceuticals. Specifically, the two scientists engineered cytochrome P450 enzymes to perform carbene transfer, the carbon analogue of P450's native monooxygenation chemistry. The team's interdisciplinary approach toward catalysis combines protein engineering with transition metal chemistry to offer a sustainable method for synthesizing bioactive cyclopropanes. The two of them, along with some recent Caltech grads from their lab, have already started a small company to begin making commodity chemicals using this process.

Caltech's runner up for the 2013 SISCA competition is Raymond Weitekamp, a fourth year graduate student. His project focused on lowering costs and avoiding harmful waste products in certain manufacturing processes by making some key inputs recyclable. Weitekamp's core discovery is a method of reactivating “dead” catalysts with light, which is a significant step towards achieving truly cradle–to–cradle olefin metathesis chemistry. Specifically, Weitekamp developed a waste–free synthesis of a new kind of photoresist, with immediate applications in green microfabrication. This invention may improve the energy efficiency of high–tech device manufacture, including integrated circuits, medical devices and MEMS.

“The essence of the SISCA award is to encourage the most promising and innovative students to find new ways to combine disciplines to address the challenges that face the earth's future. Once again, Caltech has delivered great ideas and potential solutions.” said Eunice Heath, Global Director of Sustainability at The Dow Chemical Company.

Dr. Harry Atwater, Resnick Sustainability Institute Director and a Howard Hughes Professor and Professor of Applied Physics and Materials Science at Caltech, added that “The future is, to a large degree, in the hands of scientists who have the creativity to move beyond current approaches to hard problems and discover new ways of transcending costs of many of the man–made challenges created in our environment. We are very proud of the work of these students and thank Dow for its foresight with this program.”

The Dow SISCA Award

In alignment with Dow's 2015 Sustainability Goals, the Sustainability Innovation Student Challenge Award (SISCA) program was launched in 2009. To promote forward thinking in social and environmental responsibility, SISCA acknowledges the energy, commitment and enthusiasm of the students and their university professors, sponsors and facilitators who support their sustainability innovations and efforts in continued excellence. 2013 celebrates the fifth year of the SISCA program, which, since its inception, has continued to expand and now engages students from 17 universities around the world. The spirit and power of global collaboration has sparked the development of long–lasting and impactful solutions. For more information, see http://www.dow.com/sustainability/studentchallenge/.
