Devices and circuits are evolving to implement brain-inspired neural systems and brain-like energy efficiency in silicon-based computing systems, novel materials processing, and devices and circuits. 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 and 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.

This special symposium is dedicated to early-career professionals in electrochemistry and materials science from the Western North America region. This symposium is designed to spotlight emerging voices in the field and strengthen the academic and professional network of early career researchers across Western North America. Its primary aim is to foster meaningful connections among scientists and engineers, introduce relevant research grant opportunities, and provide space for participants to share their work and experiences. The event also serves as a platform to discuss common challenges, regional perspectives, and collaborative opportunities across the western coast. The symposium includes:
• Early-career presentations: Five-minute preview presentations by individuals who are either (1) within five years of starting a new research topic or career track, or (2) 35 years of age or younger.
• Invited keynote speakers: Experts from grant agencies and industry sponsors who deliver invited talks and remain available during extended coffee breaks to provide feedback and engage in networking discussions.

Early-career presentations:
Inspired by the successful 2024 European Section Symposium, the submission process requires meeting the age/career stage requirement and answering this two-part question:
1) “Are you located in Western North America (e.g., California, Oregon, Washington, Idaho, or Western Canada)?”
2) “Would you like to participate in the special symposium, Young Researchers in Western North America?”

Respondents answering “Yes” to both questions are invited to deliver a five-minute preview presentation (probably on Sunday, running into Monday) before the main conference starts. This serves as a teaser to encourage broader attendance at their full-length talks taking place during the main conference. Abstracts for full-length talks (oral or poster) are submitted to a symposium in the author’s technical interest area.

Five-minute presentation format:
• Minute 1: Take the stage and upload slides.
• Minutes 2–4: Deliver a condensed version of the full-length talk using only three slides: (1) Title slide, (2) Content overview, (3) Date/time/location of full talk.
• Minute 5: Remove flash drive and exit the stage.

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 efforts are 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, especially with respect to N conversion/measurement, is required in the abstract (e.g., argon controls, isotope labeling, and assessing NOX contaminants for electrochemical reduction of nitrogen to ammonia). 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 by-products;
3) Electrochemically driven nutrient recycling or recovery;
4) Experimental techniques, controls, and methodology to ensure rigorous evaluation of performance.

Heterogeneous functional materials (HeteroFoaMs) are pervasive in electrochemical devices. These devices consist of multiple materials combined at multiple scales (from atomic to macro) that actively interact during their functional history in a manner that controls their collective performance as a system at the global level. Examples include composite mixed conductors, nano- or microstructured heterogeneous materials, mechanical alloys, nanostructured interfaces and heterostructures, and many other combinations that typically serve as the heart of devices such as fuel cells, electrolyzers, batteries, solar cells, capacitors, thermoelectrics, and separation membranes. The functional behavior of these materials occurs at multiple scales of length and time. The electrochemical science that makes such technologies work rests on our knowledge and understanding of the science that controls the functionality of such materials, and the design of new HeteroFoaMs to enable new devices or improve the performance of existing devices. The principal motivation for this symposium is to provide a forum to discuss the science that controls emergent properties in heterogeneous functional materials as a foundation for design of functional material devices with performance not bound by constituent properties. The symposium includes invited speakers to present a general definition of the problem, the state of the art on a few specific technology areas such as electrochemical conversion of energy to electricity, membranes for selective transport, and charge storage devices.

The purpose of this symposium is to bring together leading experts with a variety of different experimental and theoretical skills and backgrounds working in areas of electrical impedance techniques and analytical methods. Impedance can be employed for materials analysis and condition monitoring, directly determine a variety of variables such as motion, chemical composition, or electric field, and indirectly, sense many other variables that can be converted into motion or permittivity, such as pressure, acceleration, fluid level, and fluid composition. Impedance spectroscopy-based measurements represent a rich multi-discipline area of science that has been applied to a large number of important areas of research, such as corrosion studies and corrosion control; monitoring of properties of electronic and ionic conducting polymers and coatings; measurements in energy storage, batteries, and fuel cells-related systems; mechanical measurements; biological, biocellular, and biomedical sensors; measurements in semiconductors, solid electrolytes, and electronic conductors; and studies of electrochemical kinetics, reactions, and processes and their control.

The aim is to show the power of electrochemical impedance spectroscopy for understanding electrochemical systems: characterizing homogeneous and heterogeneous materials by their charge transport and dielectric properties; recognizing effects and signatures of surface layers; studying space charge regions at the interfaces or in the bulk solution; determining kinetics of electrochemical and chemical reactions. The symposium also welcomes papers dedicated to fundamental research in electrochemical impedance devices and recent advances in the impedance instrumentation; data collection and processing; new algorithms for data fitting and process monitoring, where it relates to electrochemistry and materials science.
