The Heh-Won Chang, PhD Fellowship in Green Chemistry provides financial support to full-time graduate students conducting research in green chemistry. The funds may be used for any purpose, including conference travel, professional development, and living expenses, while the recipient is in graduate school.
Green chemistry is the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. Green chemistry encompasses all aspects and types of chemical processes, including synthesis, catalysis, analysis, monitoring, and separations, and reaction conditions that reduce impacts on human health and the environment relative to the current state of the art. Research being conducted by applicants to the Chang Fellowship must address one of the following focus areas:
1. The use of greener synthetic pathways. This focus area involves designing and implementing a novel, greener pathway for a chemical product. Examples include synthetic pathways that:
- Use feedstocks that are of lower inherent hazard to humans or the environment, and/or that are renewable (e.g., biomass, natural oils).
- Use novel reagents or catalysts, especially those that use earth-abundant metals, organocatalysts, biocatalysts, and microorganisms. Precious metal (i.e., Pt, Pd, Ru, Rh, Ag, Os, Ir, Au) containing catalysts at concentrations greater than 10 ppm are strongly discouraged unless these are heterogeneous and greater than 95% recyclable.
- Are natural processes, such as fermentation, or use biomimetic processes.
- Are mass and energy efficient and step-economical.
2. The use of greener reaction conditions. This focus area involves improving conditions other than the overall design or redesign of a synthesis. Greener analytical methods often fall within this focus area. Examples include reaction conditions that:
- Replace hazardous chemicals (starting materials, reagents, etc.) and solvents with chemicals and solvents that have a lower impact on human health and the environment.
- Use solventless reaction conditions and solid-state reactions.
- Use novel processing methods that prevent pollution at its source.
- Eliminate energy- or material-intensive separation and purification steps.
- Improve energy efficiency, including reactions running closer to ambient (T and P) conditions.
3. The design of greener chemicals. This focus area involves designing and implementing chemical products that are less hazardous than the products or technologies they replace. Examples include chemical products that are:
- Less hazardous (environmental, health and safety) than current products.
- Inherently safer with regard to accident potential.
- Recyclable or biodegradable after use.
- Safer for the environment (e.g., do not deplete ozone or form smog).
Award Amount: $5,000
Eligibility: The Heh-Won Chang, PhD Fellowship in Green Chemistry is open to full-time graduate students across the globe who are currently conducting research in green chemistry. Applicants must have at least one full year of study remaining in their graduate program. Recipients must present their research at the annual Green Chemistry & Engineering Conference, where the award will be formally presented.
