| Project Description | As part of a team working on a USDA/NIFA funded project entitled, “Nonthermal Decontamination of Leafy Vegetable Food Products Using Nanosecond Pulsed Electric Field Exposures,” the Research Computing Facilitator (RCF) will help enable specific analytical work by performing COMSOL Multiphysics simulations of local electric field distributions, current densities, and Joule heating within leafy green vegetable tissue and bacterial suspensions between electrodes in order to predict threshold electric pulse exposures for thermal tissue damage. Matlab or Python scripts will be written for further analysis of the simulation data. Three-dimensional models of electrodes, custom exposure chambers, and tissues or cell suspensions will be constructed using a CAD software such as Solidworks and then imported into COMSOL. The RCF will take the lead on migrating this work to an HPC platform for production modeling. Computationally-intensive simulations will be run on the Rowan University Computing Cluster (RUCC). The RCF student working on this project will interface with faculty, staff and other students to: • Construct models that accurately simulate designed experimental conditions, • Access, use, and retrieve data from RUCC, • Create and test code to analyze data over the tested parametric spaces, • Document the construction of simulations and written code, so that others can follow, • Manage and organize all data within approved digital storage, and share all data with the faculty leader in appropriate file formats, and • Assist in the interpretation, write-up, and publication of results. In addition to potential academic publication(s) and conference presentation(s), milestone deliverables from this project will be shared publicly via posting to the project leader’s website. |

| Notes | |
| What is the impact on the development of the principal discipline(s) of the project? | The project resulted in prediction of thermal deposition associated with Joule heating during pulsed electric field exposures of spinach leaf tissue. Agriculture and food safety benefits from the threshold treatment parameter values calculated, giving boundaries to pulsed electric field exposures applied for extraction, drying, decontamination, or electrotransfection of leafy green plant tissues |
| What is the impact on other disciplines? | The results of this project also provide useful data points to the disciplines of bioelectricity and botany. |
| Is there an impact physical resources that form infrastructure? | N/A |
| Is there an impact on the development of human resources for research computing? | Yes, one student developed skills for research computing. |
| Is there an impact on institutional resources that form infrastructure? | N/A |
| Is there an impact on information resources that form infrastructure? | N/A |
| Is there an impact on technology transfer? | N/A |
| Is there an impact on society beyond science and technology? | Yes, possible indirect benefits to society include food products that require less energy to process and are safer to consume. |
| Lessons Learned | The student learned about electrophysical properties of biological materials, how to construct finite element models of composite materials, and more advanced COMSOL modeling techniques. The student also realized and informed Rowan University of necessary licenses and updates needed to operate COMSOL on Rowan University’s Computing Cluster (RUCC). |
| Overall results | Simulation results indicate negligible temperature rise within leaf tissue during pulsed electric field exposures with parameters being used for decontamination treatments. These results have been used as supporting information for a manuscript entitled, “Threshold Microsecond Pulsed Electric Field Exposures for Change in Spinach Quality,” currently undergoing peer review. |
