Nanostructured alloying electrode materials such as antimony, germanium, and silicon are highly promising materials that offer potentially low-cost, high-power-density, and high rate capability. However, developing a strong understanding of the morphology and tying the morphology to performance is difficult because electrodes are typically made up of a disordered mixture of active material, polymeric binder, and conductive carbon. Therefore, the goal of my research is to utilize in-situ electrochemical techniques such as the galvanostatic intermittent titration technique (GITT) and electrochemical impedance spectroscopy (EIS) to fully understand how alloying type nanomaterials behave in multicomponent electrochemical systems such as batteries. The investigated materials will be synthesized using...

My research focuses on new, advanced materials for efficient energy storage and electrocatalysis. Specifically, I will synthesize liquid crystalline metal–organic macrocycles that combine the porosity, chemical tunability, and high conductivity of 2D metal–organic frameworks (MOFs) with the solution-processability, self-healing, and stimuli-responsiveness of liquid crystals. 2D MOFs are generally isolated as microcrystalline powders, leading to poor electron transport across grain boundaries. In contrast, liquid crystals are solution processable and can be macroscopically aligned, eliminating this issue. I have synthesized tetrahydroxytriphenylene ligands that should bind to square planar M(II) cations to form hexagonal macrocycles. The desired macrocycle features a π–d conjugated core that should facilitate rapid charge...

My research focuses on the integration of solid binding peptides (SBPs) within the framework of proton-transporting transmembrane proteins to create new devices and materials that will enable next-generation energy systems. SBPs are combinatorially selected peptides that bind with high affinity to inorganic materials. By genetically inserting these peptides at various sites of functional transmembrane proteins (e.g., light-activated ion transporters), and by exploiting emerging techniques to isolate and stabilize the resulting chimera in polymeric nanoparticles, I intend to fabricate new devices to control charge transfer and chemical potential across interfaces in response to light illumination. Additionally, I am interested in developing responsive materials in which...

I will focus on organic mixed ionic-electronic conductors (OMIECs), which are often soft polymers or polymer blends with conjugated structure. They are promising candidates for supercapacitor and battery electrodes as they have great ionic-electronic coupling property and decent capability of ion and electron transportation. Also, the fabrication could be easily scaled up using roll-to-roll printing as most OMIECs are solution processable. In specific, I will synthesize PEDOT or Polythiophene with carboxybetaine/sulfobetaine zwitterionic side chains via chemical polymerization. EIS and OECT will be applied to characterize the synthesized materials for capacitance and kinetics studies. Higher specific capacitance and charging rate are expected as the zwitterion...

My research focuses on developing a computational artificial intelligence framework for 3D lithium-ion batteries. Conventional battery manufacturing only considers monolithic, planar electrode architectures that have a fundamental trade-off between power and energy density. 3D batteries overcome this trade-off by enhancing ion transport with their engineered electrode architectures. I am currently developing a model framework that can automatically generate and optimize electrode architectures based on a set of user-defined design requirements.

My research will focus on self-assembly of organically cross-linked structures of 2D materials for clean energy applications. The 2D semi-conducting and quantum materials have well-defined atomic structure and architecture. Integrating 2D materials with functional organic molecules into well-controlled molecular to nano-scale architectures will lead to novel and synergistic properties and functions. Monolayer or few layer MoS2 will be prepared through mechanical and chemical exfoliation. Organic molecules will be self-assembled on the nanoflakes and cross-linked into layered structures. The unique band structures, limited electrons, and incomplete band bending of such materials will be exploited to realize unique catalytic, transport, and storage properties. In-situ STM, novel...
