Abstract: Organic semiconducting polymers present a versatile platform for energy conversion and storage and sensing devices due to tunable optical and transport gaps, compatibility with electrolytes, and scalability via solution processing. The Center for Soft Photoelectrochemical Systems (SPECS) is an Energy Frontier Research Center that focuses on understanding the fundamental factors that control charge and matter transport processes that underpin energy conversion and storage technologies across spatiotemporal scales in scalable, durable, π-conjugated polymer materials. Within SPECS, we aim to establish design rules for robust photocathode systems that elucidate key structure–property relationships related to charge transport, charge transfer, and operational durability.

Our initial device employs a bulk heterojunction (BHJ) strategy, combining PTB7-Th (hole transport) and N2200 (electron transport) polymers, deposited on passivated ITO and capped with a hydrogen evolution reaction (HER) catalyst (e.g., Pt or RuO₂), all immersed in an acidic electrolyte. Insights from optoelectronic analogs guide our focus toward enhancing chemical and mechanical interfacial stability and enabling selective charge extraction.

Efforts that will be described in this talk include multiple spectroelectrochemical methods and theoretical efforts to reveal the impact of electrochemical doping and ultimately serve as signatures to drive charge transfer reactions such as solar fuel production. Other highlights will include opportunities to functionalize various interfaces to increase rates of hydrogen evolution.

Abstract: The Air Force Research Laboratory (AFRL) is the primary research and development organization for the United States Department of the Air Force. Our team is developing new materials and manufacturing approaches to enable the next generation of electronic and optoelectronic devices that are critical for national security. Technologies such as integrated photonics, photodetectors, optically activated switches, and electro-optic modulators demand materials with electrical and optical properties that can be precisely tuned. One promising strategy is to combine organic and inorganic components in hybrid material systems, where carefully engineered interfaces can yield properties that are not possible in either component alone.

In this presentation, I will highlight three material platforms under development in the Materials and Manufacturing Directorate at AFRL where these hybrid interfaces play a central role: transition metal dichalcogenides for optical scattering, MXenes for electromagnetic interference shielding, and organic metal halide perovskites for detecting and generating polarized light. In each case, advances in synthesis, processing, and nanoscale to microscale characterization of the organic/inorganic interfaces are key to achieving the desired performance.

Abstract: The Periodic Table is a cornerstone of chemistry, but its validity is challenged by the extreme properties of superheavy elements (SHEs, Z ≥ 104) and actinides (Z > 88). Relativistic effects, stemming from their large nuclear masses, significantly alter their chemical behaviors, potentially limiting the predictive power of the Periodic Table. Recent breakthroughs have provided insights into the chemistry of these elements, including the direct identification of molecular species formed by actinium (Ac, Z = 89) and nobelium (No, Z = 102) ions.

Using a cutting-edge, atom-at-a-time technique at the 88-Inch Cyclotron Facility at Lawrence Berkeley National Laboratory, we have synthesized and characterized molecular species produced by these ions in reactions with H2O and N2. Our findings underscore the importance of direct identification in SHE chemistry experiments and offer new perspectives on the chemical properties of these enigmatic elements.

This presentation will explore the current state of superheavy element chemistry research, highlighting recent advances and future directions for unraveling the mysteries of SHE chemistry. By pushing the boundaries of our understanding, we aim to shed light on the chemical behaviors of these extraordinary elements and challenge our current understanding of the Periodic Table.

Bio: Jennifer Pore leads an innovative gas phase chemistry program at Lawrence Berkeley National Laboratory, where she investigates the fundamental properties of superheavy elements, examining them one atom at a time. A San Francisco native, she earned her Bachelor of Science at Mills College, a women's college in Oakland, CA. She then moved to Canada to complete her Master’s and Ph.D. in nuclear science before returning to California and joining the Lawrence Berkeley team. Her primary research interest focuses on probing the chemical properties of superheavy elements to explore whether the periodic table should be reorganized. Jennifer has recently received a DOE Early Career Award to further investigate the chemistry of superheavy elements.

Abstract: Sensors and actuators are fundamental building blocks of next-generation human-machine interfaces. This talk presents our recent efforts to establish closed-loop, bidirectional communication and feedback within living systems, with an emphasis on the chemical dimension. The first part of the talk introduces a novel class of flexible, miniaturized probes inspired by biofuel cells for monitoring synaptic release of glutamate in the central nervous system. The resulting sensors can detect real-time changes in glutamate within the biologically relevant concentration range. These advances could aid in basic neuroscience studies and translational engineering, as the sensors provide a diagnostic tool for neurological disorders. The second part of the talk presents our recent work on a bio-integrated gustatory interface, “e-Taste,” which addresses the underrepresented chemical dimension in current VR/AR technologies. This system facilitates remote perception and replication of taste sensations through the coupling of physically separated sensors and actuators with wireless communication modules. Together, these efforts aim to advance the co-design of systems capable of capturing signals and providing feedback, addressing the relatively underexplored chemical aspect in many fields.

Abstract: Synthetic DNA nanotechnology facilitates the design and fabrication of nanoscale particles and devices with diverse applications. Leveraging a growing toolkit of DNA self-assembly methods, it is possible to construct both two- and three-dimensional structures ranging from nanometer to micron scales. The unique biophysical and biochemical properties of DNA—combined with its compatibility with various organic and inorganic nanoparticles and its predictable base-pairing rules—have made it an ideal material for single-molecule studies, photonics, plasmonics, synthetic biology, and healthcare applications. In this work, we present our efforts in developing DNA-based platforms to precisely organize inorganic and organic nanoparticles and biosensors. We investigate how these DNA scaffolds can control the positioning and orientation of nanoparticles to enhance their photophysical properties. Additionally, we explore the behavior of DNA nanostructures when introduced into mammalian cell cytosol, a critical step toward creating biocompatible delivery systems for therapeutic and diagnostic purposes. Finally, we will discuss our recent efforts in building gene-encoded DNA nanoparticles, a promising advancement in the development of targeted delivery systems.
