Fellowship funds may be used for any purpose (e.g., conference travel, professional development, and/or living expenses) while the recipients are in graduate school. Heh-Won Chang, Ph.D. Two fellowship winners are selected annually.

Award Scope and Objectives

• 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 students applying for the Chang Fellowship must address one of the following focus areas:
  • The use of greener synthetic pathways:
    • This focus area involves designing and implementing novel, greener pathway(s) for the synthesis of 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. Catalytic systems that contain precious metals (e.g., Pt, Pd, Ru, Rh, Ag, Os, Ir, Au) at concentrations greater than 10 ppm are strongly discouraged unless they are heterogeneous and greater than 95% recyclable.
      • Are natural processes, such as fermentation or use biomimetic processes.
      • Are mass and energy efficient and show economy of process (number of steps, separations, purifications, etc.).
  • The use of greener reaction conditions:
    • This focus area involves improving conditions other than the overall design or redesign of a synthetic pathway. Greener analytical methods often fall within this focus area. Examples include reaction conditions that:
      • Replace hazardous chemicals (starting materials, reagents, etc.) and solvents with alternatives 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 conditions (temperature and pressure).
  • 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).

Funding Information

• Fellowship awardees receive a one-time (non-renewable) payment of $5,000.

Eligibility Criteria

• Full-time graduate students (U.S. or international) are eligible to apply for this award. Applicants must demonstrate the relevance of their research to green chemistry and/or engineering and have at least one full year of study remaining in their graduate program from the time of the expected award. (For example, students applying for the 2026 Fellowship should intend to continue research at least through the end of the 2026-27 academic year.)

Judging Criteria

• An independent panel of experts selected by the ACS GCI will judge the applications. This panel may include members of the scientific, educational, industrial, government, and environmental communities.
• The judging panel may request verification of any activities described or claims made in applications that are selected as finalists. The judges will select the students whose projects best meet the selection criteria for the award.
