This poster session provides a forum for graduate and undergraduate students to present research results of general interest to ECS. The session’s purpose is to foster and promote work in both electrochemical and solid state science and technology, and to stimulate active student interest and participation in ECS. Posters accepted for presentation in this session are eligible for General Student Poster Awards. To be considered for awards, student poster authors must (1) upload a digital poster and (2) be present during the in-person judging session. The top three student authors receive cash prizes: $1500 for first place, $1000 for second place, and $500 for third place.

While graduate students and postdoctoral fellows accomplish the lion’s share of research, there are a number of undergraduate only institutions that are making significant contributions to electrochemistry. These are wonderful opportunities for the students, but certainly present additional challenges to the primary investigator not seen at the more research-focused institutions. This symposium calls not just for research methods and papers from an undergraduate dominated setting, but also teaching and curriculum ideas for incorporating electrochemistry into undergraduate programs. We look for this symposium to shed some light on what has been accomplished and some thoughts on what may be possible. Papers on basic and applied research and teaching in all areas of electrochemistry, electrochemical systems, and physics related to solid state and electrochemical science and technology are solicited.

9. Novel approaches to teaching electrochemistry.

Keynote lectures are presented by invited speakers. A poster session is planned. Student participation is highly encouraged. It is anticipated that some funds will be available to support students and young scientists.

Electrochemical systems, in addition to enabling sustainability through energy generation and storage, can play a central role in enabling the cradle-to-cradle strategy in materials. This strategy encompasses three aspects:
1) Sustainability-driven right-sized design using electrochemical processing of materials through electrochemical methods such as electrodeposition;
2) Electrochemical means of recovering valuable materials after products reach the end of life;
3) Design and development of recycling methods for materials used in electrochemical devices such as batteries, fuel cells, electrochemical reactors, etc.

Papers are invited in the areas of

• Low or zero carbon ways of synthesizing the right structures and smart structures through electrodeposition and electrochemical machining;
• Research, design, and development of electrochemical reactors to aid in the recovery of rare earth elements, photovoltaic components, battery materials, electronic devices and components, materials from electroplating operations, etc.;

This symposium explores advances in fundamental and applied electrochemistry and electrochemical systems to enable efficient, economical, and sustainable chemical manufacturing. With renewable electricity increasing its penetration into the grid, opportunities to use electrochemistry in chemical manufacturing economically and sustainably are ever growing. By utilizing electrochemical methods, processes can be decarbonized when using renewable electricity, wastes and hazardous intermediates can be reduced or eliminated, alternative feedstocks can be used, and modular chemical production units can be implemented.

1. Electrolysis of organics such as those used for manufacturing of commodity chemicals, fine chemicals, and pharmaceuticals;
2. Water electrolysis for hydrogen and oxygen utilization in chemical manufacturing;
3. Inorganic electrolysis including, but not limited to, chloro-alkali and aluminum electrowinning;
4. Electrochemical separations for chemical manufacturing;
5. Electrolysis for recycling/upcycling;
6. Materials degradation issues impacting chemical manufacturing processes and equipment.

Contributions may address areas including electrocatalyst, electrolyte, and membrane development; electrochemical reaction engineering; reactor design; separation unit design; integration of electrochemical units into chemical production processes; process intensification; corrosion/degradation; and techno-economic/life cycle analyses. Experimental, computational, modeling, and simulation presentations, as well as process development efforts, are solicited. Invited and submitted presentations from industry, national labs, and academia are included.

With the efforts to mimic biological neural systems and demonstrate brain-like energy efficiency in silicon-based computing systems novel materials processing, devices and circuits are evolving. This symposium addresses the devices for the hardware requirements using nanoscale solid state and electrochemical materials that enable neuromorphic computing and next-generation AI technologies. This includes in-memory computing and implementation of deep neural network circuits. In some instances, materials and device co-design, and device and circuit co-design, are required through extensive simulation and processing for system implementation. Issues like energy-efficiency performance enhancement are required to emulate the brain's connectivity in hardware. The switching devices that replicate the electronic synapse need to reduce the device-to-device or in-device stochasticity.

The following are indicative topical areas to be covered by the symposium:

1. Neuromorphic computing and AI hardware related materials and devices: New devices, metals, and different switching layer materials are being considered for AI and neuromorphic computing.

Lithium ion batteries have driven the portable electronics market's tremendous growth and their use in transportation and grid storage sectors is expanding at a fast rate. Further boosting the energy density of these batteries requires higher voltages and greater electrode materials capacity. This symposium is intended to provide a forum for dissemination of new advances and developments in Li-ion batteries which includes new or improved materials and understanding, electrolytes, interfaces/interphases, separators, and electrochemical testing.

Electrical energy storage is critical for supporting the integration of renewable energy sources (e.g., wind and solar) and increasing the capacity and reliability of the future electricity grid. Electrochemical energy storage systems have the potential to fulfill this need. This symposium seeks oral and poster presentations on advances in materials, technology and designs, results of performance demonstrations, and economics analysis. The technologies of interest include redox-flow battery systems, metal-air rechargeable batteries, electrolyzers, capacitors, and other rechargeable electrochemical energy storage systems that have the potential to meet the cost and efficiency requirements of large-scale deployment.

A key prerequisite for battery manufacturing is designing cell components that fulfill the targeted performance metrics and can be scaled up in a cost-effective manner. Conventional experimental R&D efforts employing design of experiments (DoE) methods have been successfully used for materials discovery and process optimization. However, these empirical methods are often time and resource expensive. Thus, a new battery innovation may take years to be deployed in production. Recently, high throughput (HTP) experimentation and machine learning (ML) have been introduced to accelerate battery materials discovery and manufacturing optimization by rapidly revealing patterns that are difficult to recognize using conventional analysis methods. Therefore, combinations of DoE, HTP experimentation, and digital tools including ML/AI have received increasing attention. Furthermore, there has been increased attention paid to sustainable manufacturing, including design of battery cells, modules, and packs with reduced energy and raw material waste streams. Ultimately, end-of-life considerations must be taken into account, which requires new processes for recycling. Finally, new manufacturing processes have been developed for control of advanced electrode architectures, including solid-solid interfaces in solid state batteries. Accordingly, researchers seek to speed up materials discovery, manufacturing optimization, technology integration in real battery cells, and battery recycling, with the goal of overcoming tradeoffs between performance, quality control, throughput, cost, and sustainability during manufacturing.

In this symposium, we invite world-leading experts/researchers in this area to discuss topics broadly covering the science of materials scale-up, high throughput synthesis and characterization, ML/AI assisted materials discovery and manufacturing optimization, sustainable manufacturing, recycling, and advanced cell integration, and manufacturing technologies. The scaled-up material systems and processes covered include, but are not limited to, cathodes, anodes, separators, liquid electrolytes, and solid electrolytes. Experimental and computational studies are equally welcome. Student participation is highly encouraged.

Sustainable economic growth and high quality of life require an abundant supply of clean and affordable energy. Future energy sources include solar, wind, and nuclear - all of which can produce electricity as the primary form of energy. The conversion of this electrical energy to fuels (e.g., hydrocarbon or hydrogen) using common chemicals such as carbon dioxide and water through electrochemical processes (e.g., electrolysis reactions), provides an opportunity to remove the temporal variation in the energy supply from solar and wind energy. Electrolysis reactions may involve protons, hydroxide, oxide, or other ions. This symposium provides an international forum for the presentation and discussion of the latest developments on electrolysis and related topics. The emphasis of this symposium is on recent advances relevant to the conversion and utilization of CO2 and/or H2O for synthesis of fuels and other chemicals. The application of the same cells as fuel cells is of special interest because reversible cells that may be coupled with renewable or nuclear electric power production in order to increase efficiency through energy storage are of particular importance.

1. Electrolysis cells including electrolytes, electrodes, seals, and interconnects for the conversion of CO2 and H2O to fuels;
2. Solid oxide fuel cells and protonic ceramic fuel cells;
3. Electrocatalytic phenomena in oxygen electrodes and fuel electrodes;
4. Electrochemical and chemical technologies for CO2 separation;
5. Novel materials or concepts for CO2 conversion and capture.

Significant coupling often exists between the electrical, chemical, and mechanical responses of the materials enabling batteries, fuel cells, electrolyzers, chemical separators, chemical actuators, and other high-performance energy conversion/storage devices. In these systems, electrochemical reactions affect stress evolution, deformation, and fracture. Similarly, stress evolution, deformation, and fracture can also affect electrochemical properties, device performance, and durability. This symposium provides a forum for the presentation of original research concerned with the interplay between mechanics and electrochemistry. Topics of interest include, but are not limited to, experimental and/or modeling studies of:

• The effect of stress and strain on: the surface and bulk atomic structure of electrochemically active materials; defect thermodynamics (point defect concentrations, chemical expansion coefficients, etc.) of electrochemically active materials; diffusion kinetics (diffusion coefficients, surface exchange coefficients, etc.); catalytic activity; electronic structure of electrochemically active materials; reaction pathways; phase transformations (phase-boundary shifting, ferroelastic domain switching, strain-induced self-assembly, etc.) in electrochemically active materials; microstructural evolution of electrochemically active materials; and performance and durability of electrochemically active materials and devices.

Recovery, conversion, and reuse of energy-dense/expensive molecules like N and P compounds have attracted increasing attention in the electrochemistry community as we increasingly need green energy carriers, and to address global nutrients and water/energy sustainability issues. Significant R&D effort is ongoing in the field to develop efficient and safe processes for fuel and nutrient recovery. There is also a need for ongoing conversations in the scientific community around experimental techniques, controls, and methodology to ensure robust and accurate results in this emerging area. As such, a statement regarding controls is required in the abstract (e.g., argon controls, isotope labeling, and assessing NOX contaminants for electrochemical reduction of nitrogen to ammonia). In this symposium, the following topics are of interest:

1. Using electrical energy to convert nitrogen-containing compounds into useful products;
2. Using nitrogen-containing compounds as fuel which may also produce other useful byproducts;
3. Electrochemically-driven nutrient recycling or recovery;

The symposium also invites papers in which nanostructured materials and interfaces are being integrated into electrochemical devices that benefit from or display specific properties that arise from the nanoscale features.

Electrosynthesis is on the rise, with new prospects in scope and scale. The realization that electricity potentially coming from renewable energy technologies can be used not only to replace some traditional synthetic methods but to optimize processes, increase safety, decrease environmental impact, and offer alternative reaction mechanisms, presents a paradigm shift in chemical production. This includes vast classes of substances, from commodity to fine chemicals, electrosynthesis and modification of polymers, and schemes coupling co-electrolysis with chemical upgrading. New classes of reactions, device configurations, and schemes for potential and current control bring also new challenges for exploring product distributions online and in real time, understanding homogeneous and heterogeneous reaction intermediates, determining the rates of chemical and electrochemical steps, and exploring the role of solvents, reaction conditions, and device components on the outcome of (electro)chemical reactions. This symposium seeks oral and poster presentations on electroanalytical approaches to address these pressing challenges. We seek to bridge a dialogue between synthetic, analytical, and electrochemical communities that helps us inform electrosynthesis to drive this field forward into its maximum impact. Topics of interest include, but are not limited to:

1. In situ/operando approaches using hyphenated methods to electrochemistry (e.g., LC/GC, MS, IR, NMR, ESR, etc.) for characterizing chemical intermediates and products in electrolyte solutions undergoing electrolysis;
2. New methods and devices for measuring rate constants of chemical and electrochemical reactions involved in electrosynthesis;

5. Interfacial methods to probe electrochemical reaction mechanisms and adsorbed intermediates at electrodes and other boundaries (e.g., emulsions, liquid/liquid interfaces, three phase boundaries);
6. Mechanistic considerations involving alternative electrolytes and methods to understand factors limiting the stability or viability of electrolytes during electrosynthesis;
7. Electrochemical simulations of diverse mechanisms involved in homogeneous and heterogeneous electrode reactions of interest to electrosynthesis;
8. Experimental or theoretical considerations of electrosynthesis on flow and batch devices and those involved in co-electrolysis or any other modality of preparative electrochemistry.

Practicable construction of quantum computers is limited by the availability of robust, tangible qubits. Several groups have proposed that paramagnetic molecules could be used as qubits. Most research has been devoted to organic radicals, centers within polyoxometallates and other metal cage complexes, or simple coordination complexes. Molecular qubits might not have phase memory times as long as those of other quantum systems, and hence performing multiple operations on molecular electron spin qubits could be challenging. There have been considerable advances in improving phase memory times through intelligent chemical design since the initial measurements that established the feasibility of using molecules in this context. Second, molecules are not as compatible with the integrated circuits used in information processing as nanostructures created by lithography.

Early proposals for spin qubits in semiconductors were envisaged using large exchange interactions to couple neighboring electron and/or nuclear spin qubits. The exchange interaction generates a natural two-qubit gate by conditionally swapping the electron spin states if they are anti-parallel. Experimentally, this requires tuning the exchange energy up to gigahertz frequencies over a relatively small range in voltage detuning, which makes this challenging. One such example is spin qubits in gate-defined quantum dots (QDs) which offer great potential for quantum computation due to their small size and relatively long coherence times. Single-qubit gate fidelities over 99.9 percent and two-qubit gate fidelities over 99 percent have already been demonstrated. Two approaches to realizing a two-qubit exchange gate using gate-defined quantum dots have been pursued: the controlled phase (CZ) and the controlled rotation (CROT) operations. When combined with single-qubit rotations, any of these three entangling gates are sufficient to perform universal quantum computation. Controlling the electrochemical potential of these quantum dots is important in controlling the device. The electrochemical potentials of the reservoirs are aligned with the electrochemical potentials of the two quantum dots, such that electrons can sequentially tunnel through the two dots. Increasing the voltage applied to lower the tunnel barrier between the dots would eventually reach the point where one large dot is formed as the gradual transition from triple points to single, parallel, and evenly spaced Coulomb peaks. This shows the tunability of the interdot tunnel coupling in this double dot, which is advantageous for two-qubit control in such a system.

These were examples using molecular or quantum dots, but other systems may be envisioned which utilize electrochemistry as a means to build, address, and read practical qubits. Therefore, papers considering the issues above, the electrochemical properties of these molecular systems, and the aspects of electrochemical control are welcome.

Sensors are being used increasingly in various energy production, conversion, and storage systems in order to improve their efficiency and reliability, and to monitor their state of health. Heightened concerns regarding the environmental impact of fossil fuel use have resulted in increased investment in clean energy conversion and storage technologies including batteries, fuel cells and electrolyzers. Interest in hydrogen as a viable carbon-free energy carrier has increased, and several countries are developing plans for vastly expanding their hydrogen infrastructure. The widespread deployment of these clean energy conversion and storage technologies can benefit greatly by the incorporation of sensors that provide information on the state of health of these devices. Moreover, the incorporation of sensors and feedback control within energy conversion and storage systems can improve their efficiency and safety.
