Electrochemistry will no doubt play a critical role in establishing the processes, systems, and monitoring to support advances in space activities. This interdisciplinary symposium brings together speakers from across a broad range of disciplines to discuss how advances in research and development for electrochemistry in space are addressing these exciting challenges and opportunities. This symposium also addresses how the features of extraterrestrial environments such as low gravity, extreme temperatures, and remote operations impact electrochemical processes as well as component design and operation. We want to facilitate broad interdisciplinary conversations through this symposium.

This symposium focuses on issues pertinent to advances in traditional damascene interconnects, and new materials and integration methods for 3D interconnects. An emerging technology or device architecture called 3D integration is based on the system performance gains that can be achieved by stacking and vertically interconnecting distinct device layers. The 3D concept of replacing long 2D interconnects with shorter vertical (3D) interconnects has the potential to alleviate the well-known interconnect (RC) delay problem facing the semiconductor industry today. Additional benefits of the 3D process include reduced die size and the ability to optimize distinct technologies (analog, logic, RF, etc.) on separate vertically interconnected layers. An application area where large performance gains can be obtained is high-density device/sensor arrays where processing power is placed within each individual device. Damascene copper interconnects, introduced at the 0.25 µm node, have spanned six technology nodes, and are expected to be used for the foreseeable future. Despite the history of success, there are new challenges including increases in effective resistivity, electromigration and stress migration resistance, and the integration of porous low-k dielectrics and air gaps. This symposium brings together researchers to discuss the challenges and solutions to extend damascene copper interconnects well beyond the 45 nm node. The aim of this symposium is to discuss the proposed architectures and applications of 3D integration, and the various enabling materials and processes that are required to bring the technology into full commercialization. Broadly, the enabling process technologies include wafer/die thinning, wafer/die bonding, and vertical interconnect fabrication. Each of these process technologies will leverage novel materials, and much of the emphasis of this symposium is was on the materials science of these 3D integration materials. Ideally, this symposium will bring together researchers to discuss the various merits of the presented 3D device architectures, materials, and fabrication methodologies. Topics of interest include, but are not limited to: (1) Methods to reduce increases in effective resistivity; (2) Methods to mitigate electromigration and stress migration issues; (3) Advanced barrier/seed processes including ALD and electroless films; (4) Porous low-k ILDs and air gap processing (including deposition and etching); (5) Novel electrodeposition and CMP processes; (6) 3D process integration methodologies; (7) 3D design and architectures; (8) Simulation and modeling of 3D integrated devices; (9) Materials and techniques for die and wafer bonding; (10) Processing and handling of thin wafers and dice; (11) Materials for temporary die and wafer bonding; (12) Vertical interconnect fabrication technology; (13) Materials for vertical interconnects: insulators, barriers, and metals; (14) Reliability of 3D interconnects; (15) Novel test and measurement of 3D integrated devices; (16) Thermal management in 3D integrated devices; (17) Epitaxial and recrystallization approaches to 3D integration; (18) 3D integration of heterogeneous materials;(19) Thermomechanical reliability and electromigration in 3D integrated devices.

Production of renewable energy requires large quantities of water, and supply of fresh water needs energy. Semiconductors play a huge role in disrupting, to some extent, this interdependence. For example, semiconductor-assisted photocatalysis and plasma-assisted processes are highly useful in the removal of pollutants, dyes, and harmful microorganisms from water. Contextually, this symposium aims to bring together researchers interested in studying semiconductors, materials, and processes for water remediation, such as the removal of pollutants, dyes, and harmful microorganisms from water. Also encouraged for submission are: semiconductor materials useful for the removal of emerging contaminants, such as pharmaceuticals; papers describing synthesis/fabrication and assembly of materials useful for the simultaneous removal of pollutants from water, along with its desalination; and papers describing the large-scale production of materials for water remediation are also encouraged.  

This symposium will be organized/scheduled in close collaboration with symposium L04, "Electrochemical Water Remediation.”

Atmospheric pressure plasma processing (APP) has received significant attention due to its combination of simplicity and a wide range of possibilities in surface treatments and modifications. Furthermore, atmospheric pressure plasma has a prominent technical significance due to its low-cost manufacturing and operations in contrast to a low-pressure plasma or even high-pressure plasma. This makes it an extremely versatile tool for any material processing and an emerging topic which will in future transform the plasma processing and related industry. Therefore, this symposium features the latest developments in APP design and applications. Furthermore, it was demonstrated that APPs could be successfully applied in materials science. For this reason, the papers related to atmospheric pressure plasma processing ranging from manufacturing to the deposition of coatings, surface modifications, and other treatments will be considered. This also includes the applications of atmospheric pressure plasma processing for nanofabrication, etching, conversion, or similar. Finally, the aim of this symposia is to lead and be at the forefront of research of atmospheric pressure plasma processing for all topics connected to The Electrochemical Society.

This symposium provides a forum for the presentation of new and exciting research in the area of epitaxial thin-film growth, and electrochemical materials fabrication.  This single half-day session is comprised of 40-minute invited lectures that highlight the most recent advances and trends in electrodeposition that touch on fundamentals and different areas of applications.

Additive Manufacturing (AM) is changing the standard by which metallic, ceramic, and polymeric parts are designed and made. Prevailing methods such as laser powder bed fusion or directed energy deposition are often used to form macroscopic parts via layer-by-layer melting and successive solidification. However, these same methods are severely limited in the design of materials that are reactive, brittle, exhibiting low melting point or low partial pressure. Electrochemical and electroless deposition methods, in contrast, are capable of generating 2D and 3D patterns of metallic, metal oxides, and composites through a variety of procedures, such as jet electrodeposition, laser-stimulated growth, electroforming or lithographic patterns. In recent years, thanks to additive technologies able to operate at the microscale, new possibilities have been individuated in fields like microrobotics, MEMS, and metamaterials fabrication, especially through the AM of polymeric materials. Electrochemical processing, such as electroless or electrodeposition, offers unique possibilities of integrating different materials in micro- and nanodevices. Magnetic and functional layers can be conveniently obtained surpassing the quality of those obtained by other techniques such as e-beam evaporation or sputtering.This symposium focuses on current and emerging methods to synthesize and control microstructure and properties of a wide set of materials, as well as on generating structured materials across length scales, from macro- to submicron size. Topics include, but are not limited to:(1)   AM of metals, alloys, and composites;(2)   Microstructure and properties control;(3)   Modeling and design, including process control;(4)   Applications

This symposium covers all aspects of (electro)chemically reactive materials, ranging from their modeling, synthesis, characterization, and industrial upscaling to various applications in functional electrodes (electrochemical energy conversion and storage, sensors, actuators, micro and nanoelectronics, electrochromic devices, refining and recycling processes, etc.). The materials under discussion include, but are not limited to electrodeposition of refractory metals and their alloys, metals, and alloys more negative than hydrogen reversible potential, electrodeposition of alkali metals, electrodeposition of intermetallic compounds and Eutectics, etc. Due to the limited electrochemical window of water, some interesting elements and compounds (e.g., aluminum, refractory metals) cannot be electrodeposited from aqueous solvents.

The electrodeposition of lithium and sodium metal for battery applications is of special interest for this symposium. We seek discussion between experts from electrodeposition and battery communities. Metallic lithium is considered as anode in solid state lithium metal batteries. Reversible electrodeposition and stripping with near perfect current efficiency are required for long cycling lifetime. Furthermore, lithium plating is of interest for fabrication of low-cost lithium thin foils on, for example, copper current collectors.
 This symposium focuses on novel electrodeposition processes from non-aqueous media such as organic solvents, supercritical fluids, molten salts, ionic liquids, etc. We also invite papers from non-standard and extreme conditions such as high pressure, supercritical fluids, from vapor and gas phase. From a fundamental point of view, possible topics are—but are not limited to—the role of the speciation of the metals in the electrolytes, the structure of the electrode-liquid interphase, and nucleation and growth phenomena. Also of interest are papers discussing the challenges associated with setting up, running, and maintaining a non-aqueous plating line.

Papers are solicited in areas of industrial electrochemistry and electrochemical engineering that are not covered by other symposia at this meeting. Of particular interest are papers concerning: design, operation, testing and/or modeling of industrial electrochemical systems; electrochemical waste treatment technologies, methods for electrosynthesis; electrolytic recovery of process materials; new electrode materials, new electrochemical cell designs; and electrocatalysis. Also encouraged are presentations on industrially significant areas, such as chloralkali and fluorine production; manufacture of aluminum and other metals; the use of electrochemical methods in pulp and paper bleaching; and generation of environmentally-friendly bleaching chemicals and other active oxidants. Papers may contain theoretical and experimental work, and papers dealing with either area will be considered.

In 2016, the U.S. Department of Energy (DOE) launched the Energy Materials Network (EMN) to accelerate the process of materials discovery, development, and ultimate deployment in major clean energy sectors. Innovations in clean energy technologies are vital to domestic energy security and economic growth. Consistent with the EMN vision, moving transformational energy technologies forward requires an honest discussion of the challenges and opportunities in critical materials R&D. An integrated approach spanning materials design and synthesis through process scale-up and qualification is essential to this effort. This symposium brings together materials experts and stakeholders from multiple sectors covered in the current EMN portfolio. This includes world class leaders with multi-physics and multi-scale expertise from the EMNs as well as leaders of other high impact materials initiatives in chemical and electrochemical systems for clean energy applications. Some common material challenges across all EMNs include interfaces, corrosion, performance, benchmarking, analysis, and computational modeling. It is expected that cross-cutting conversations at this session foster synergy for future collaborations.

The feasibility of performing nitrogen electroreduction reaction, or nitrogen fixation, particularly in aqueous solutions, constitutes an attractive prospect to produce ammonia under ambient, or near ambient, conditions. Development of durable, specific, and reasonably efficient low-cost catalysts remains a great challenge for electrochemical science and technology. Currently, most electrochemical approaches to N2-fixation suffer from slow kinetics due to the difficulty of achieving the appropriate adsorption and activation of dinitrogen leading to cleavage of the strong, triple N≡N bond. This symposium features presentations on research dealing with the fundamental and applied aspects of nitrogen reduction reactions of relevance to various aspects of science and existing technologies.The symposium aims to bring together researchers in different areas of electrocatalysis and materials chemistry as well as electrochemical science and technology with the intent to discuss the current state of the art and understanding of the electrochemical fixation of nitrogen.
