Frustules (Silica wall) of the diatom Thalassiosira oestrupii were researched for their capability to capture and store methane gas. Zinc chloride has ability to bond to one of the carbon-hydrogen bonds in methane. Methods of doping the frustules composed of silicon dioxide were explored using the zinc chloride, and silzic was found to be the resulting substance. This showed that zinc chloride could be present on the frustules of the diatom. Hence, it is hypothesized that it could be bonded to it creating the potential to bond with methane gas. To achieve the bond, zinc chloride must be vaporized in a vacuum chamber, then an electrical discharge added with methane gas present.

This process will have to occur after doping the diatom with zinc chloride to ensure a bond is achieved. The resulting molecule from the reaction will be methylzinc hydride, which will be bonded to the diatom frustule. The frustules of the doped diatoms could then be harvested in a centrifuge and made into a powder to be distributed onto methane-producing areas such as landfills, cow pastures, and even on Mars for possible space mining for fuel and exploration. Further research and testing is required to determine if this reaction is possible, or if a catalyst is necessary.

Session Details

This session will demonstrate that practical risk management is for everyone, regardless of a formal program. Attendees will learn actionable and simple strategies that are easy to implement, enabling them to start immediately by focusing on their top risks to build greater operational resilience and ensure the sustained success of their auxiliary enterprises.

Presenter Profile

Michelle Powell serves as the pioneering Risk Manager at Florida Polytechnic University, the state’s sole 100% STEM-dedicated institution. Having been with the university for nearly 11 years, Michelle transitioned from a leadership role in Admissions in October 2023 to establish and evolve the risk management function from the ground up. In this solo capacity, Michelle builds robust frameworks for our dynamic, young university, overseeing our insurance portfolio, consulting on third-party and event risks, and developing critical campus-wide training programs. Michelle has obtained the Committee of Sponsoring Organizations (COSO) Enterprise Risk Management certificate and the Associate in Risk Management (ARM) and Construction Risk and Insurance Specialist (CRIS) designations. Her distinct background in mathematics and engineering, combined with extensive higher education leadership, brings an analytical and strategic approach enhancing the institution’s resilience.
