Nanocarbon-based Flexible Devices: Emerging Materials and Processes
Symposium Dates: Monday, February 28, and Tuesday, March 1
Symposium Organizer and Keynote Speaker: Mostafa Bedewy, University of Pittsburgh
Keynote Presentation Title: “Direct-write of Laser Induced Graphene with Spatially Varying Properties on Polymers”
Keynote Presentation Date and Time: Monday, February 28, 10:50 a.m. PST
Location: Anaheim Convention Center, Room 260A
About the Presentation
High surface area nanocarbon electrodes for batteries, supercapacitors, and biosensors have consistently been shown to have superior performance when compared to metal electrodes. Nevertheless, major challenges hinder our ability to scalably produce nanocarbon-based electrodes with tailored morphology and surface chemistry, especially on flexible substrates. This talk focuses on a unique bottom-up approach for directly growing different types of nanocarbons on polymer films by laser irradiation. First, the talk will cover how this direct-write process, often referred to as laser-induced graphene (LIG), can be controlled to produces spatially-varying morphologies and chemical compositions, by leveraging gradients of laser fluence. Secondly, a method will be introduced to control the heteroatom doping of LIG electrodes based on controlling the atomic structure of the polymer being lased. Finally, a demonstration of these functional LIG electrodes as electrochemical biosensors will be presented for the detection of the neurotransmitter dopamine with nanomolar sensitivity.

Data-Driven, Machine-learning Augmented Design and Novel Characterization for Nano-architectured Materials
Symposium Date: Wednesday, March 2, 2022
Symposium Organizer and Keynote Speaker: Yu-chen Karen Chen-Wiegart, Stony Brook University/Brookhaven National Laboratory
Keynote Presentation Title: “Designing Nano-architectured Materials with a Machine-learning Augmented Framework”
Keynote Presentation Date and Time: Wednesday, March 2, 2:00 p.m. PST
Location: Anaheim Convention Center, Room 260C
About the Presentation
Design parameter space for nano-architectured materials is large and complex. Even with the guidance of simulation and theoretical computation, creating nano-architectured materials, despite being at the forefront of materials science, could suffer from the common issue of intuition-driven “trial-and-error” materials discovery. While there has been a significant increase in developing data-driven, machine-learning (ML) based methods for efficient materials design, only recently have researchers begun to integrate these approaches with advanced, high-throughput characterization tools. This talk aims to provide an overview on the latest development of this exciting direction in materials science and engineering. A use case of solid-state interfacial dealloying (SSID) creating bicontinuous nanostructures will also be presented; the example will highlight the use of ML-based models and algorithms to predict materials’ synthesibility as well as the promise to apply automated and autonomous experimental approaches at synchrotron facilities to further enhance and validate the ML models.

Microbiologically Influenced Corrosion - How Organisms Accelerate Materials Degradation
Symposium Dates: On-Demand Session; Presentations Available Beginning March 14
Symposium Organizer and Keynote Speaker: Andrea Koerdt, Bundesanstalt für Materialforschung und Prüfung (BAM)
Keynote Presentation Title: “Methanogen Induced Microbiologically Influenced Corrosion (Mi-MIC): Environmental Condition and Parameter Have a High Impact on the Corrosion Rate and Products”
About the Presentation
Microbiologically influenced corrosion (MIC) is a challenge for different industry sectors/infrastructure. The role of methanogen-induced-MIC (Mi-MIC) is often underestimated, due to the low corrosion rates (CR) reported so far and the suspected non-conductive corrosion product (CP), siderite. Recently, we demonstrated that corrosive methanogens have a larger impact on MIC. This difference is the result that conventional Mi-MIC studies using static incubations. This type of incubation fails to provide environmentally relevant information on the CR and CP, in particularly for methanogens. To illustrate the importance of the environment on the MIC process, we established a Multiport-Flow-Column, to simulate the natural environment. We obtained ten times higher CR than previously published under static conditions. Furthermore, we analyzed the CP with a combination of techniques (ToF-SIMS/SEM-EDS/FIB-SEM) and found that siderite is not the sole CP of Mi-MIC. This study will expand the current understanding of MIC thus aiding the development of different mitigation strategies.
