Multiscale 3D Printing of Nanomaterials-based Electronics: Yong Lin Kong1; 1University of Utah
The integration of nanomaterials with 3D printing can create functional devices with an unprecedented level of functional integration. My research focuses on the multiscale integration of nanomaterials in an extrusion-based 3D printing process, enabling the creation of electronics that can address unmet clinical needs. As an example, I will first highlight the development of the 3D printing of active electronics, which extended the reach of 3D printing. In the second part of the talk, I will highlight the development of a 3D printed gastric resident electronics system, which leverages the significant space and immune-tolerant environment available within the gastrointestinal tract to circumvent the potential complications associated with surgically placed medical implants; and explore the possibility of integrating reinforcement learning algorithm to adapt to environmental changes. Ultimately, we strive to address unmet clinical needs by creating 3D printed biomedical electronics that can better interface with a broad range of three-dimensional systems.

Well-defined 3D Printing of Titanium Carbide (Ti3C2Tx) MXene Nanosheets into Complex and Hierarchical Microarchitectures with High Aspect Ratio: Rahul Panat1; Bin Yuan1; Azahar Ali1; Chunshan Hu1; 1Carnegie Mellon University
Building functional nanomaterials into complex three-dimensional (3D) micro-architectures with high aspect ratio can provide superior device performance compared with simple two-dimensional (2D) patterns. Even though functional titanium carbide (Ti3C2Tx) MXene nanosheets have received much attention for energy storage, healthcare, advanced composites, and membranes; arranging them into well-defined complex 3D device structures remains a significant challenge and has not been realized. Among the techniques for building 3D structures, 3D printing is advantageous compared with conventional ones (e.g. lithography) as it allows for flexible customization, rapid prototyping, and minimal waste generation. We report printing of Ti3C2Tx MXene nanosheets into truly 3D microarchitectures with different geometries (including pillar array, wavy-wall array, and scaffold array), at very high aspect ratios, high printing resolution (~10 μm), excellent size controllability, and smooth surface on various substrates. This technique is critical for the fabrication and application of MXene-based high-performance 3D micro-electronics (e.g. supercapacitors, wearable healthcare devices).

Nitrogen-doped Graphene Catalysts for Advanced Electrochemical Energy Conversion and Storage Systems: Eon Soo Lee1; Niladri Talukder1; 1New Jersey Institute of Technology
This talk presents the synthesis, characterization, and improvement of nitrogen-doped graphene-based catalysts for advanced electrochemical energy conversion and storage systems. The key motivation for this research is replacing or supplementing the cost-ineffective platinum group of metal (PGM)-based catalysts that are commonly used today. We synthesized a Nitrogen-doped Graphene (N-G) catalyst by a high-impact nano wet ball (HI-NWB) milling process which showed electrochemical catalytic performance similar to the standard 10 wt% Pt/C catalyst. Later, this N-G catalyst was integrated with a metal-organic framework material (MOF) to synthesize N-G/MOF catalyst. By this approach we took the advantage of MOF’s structural feature; the high surface area of MOF can host a much higher number of catalytic active sites on the material. The N-G/MOF catalyst showed better catalytic performance than the 10 wt% Pt/C with the same loading in terms of obtained current densities from the electrochemical oxygen reduction reaction.
