Plenary Title: Hierarchical Electrode-to-System Battery Thermal Management and Modeling: Latest Developments and Future Directions
Abstract: The rapid growth of electric vehicles (EVs) and battery energy storage systems (BESS) is creating new challenges for the thermal management, safety, performance, and lifetime of increasingly large and complex lithium-ion battery systems. Addressing these challenges requires models and thermal management strategies that span multiple length scales and physical domains, from nanoscale transport in electrode materials to heat generation and degradation within cells, and to the thermal behavior of modules and packs.
This plenary lecture will present recent advances in hierarchical battery thermal management and modeling across these scales. Following an overview of battery heat generation, temperature-dependent performance and degradation, and battery thermal management systems (BTMS), we begin at the electrode level, where atomistic approaches, including density functional theory, molecular dynamics, and machine learning, provide insights into nanoscale thermal and electrochemical transport and enable exploration of novel two-dimensional materials and heterostructures for next-generation electrodes. At the cell level, we examine the thermal and electrochemical characterization of anisotropic thermophysical properties and spatially distributed heat generation, together with temperature-driven degradation and thermal runaway in large-format lithium-ion pouch cells increasingly used in EV and BESS applications. At the module and system levels, we will highlight the challenges of scaling high-fidelity physics-based models and emerging approaches that combine hierarchical cell-to-system thermal models, deep-learning surrogates, and design optimization.
The plenary lecture will conclude with a perspective on integrating these advances into battery digital twins that span scales, physics, and data, enabling faster design exploration, improved thermal management and safety, and more predictive approaches to battery system design and operation.

Plenary Title: Thermal Management of Data Centers in the Age of AI
Abstract: The extraordinary growth of artificial intelligence is driving a fundamental transformation in data-center power and thermal management. AI training and inference systems increasingly rely on high-power GPUs and accelerators, high-bandwidth memory (HBM), chiplet-based architectures, and advanced heterogeneous packaging. Individual processors are approaching and exceeding the kilowatt power level, while AI rack power densities are progressing from tens of kilowatts toward 100–200 kW and far beyond. These trends are rapidly challenging the practical limits of conventional air cooling and making thermal management a primary constraint on system performance, reliability, energy efficiency, and data-center scalability.
This presentation examines the thermal-management technologies required to support this rapidly evolving AI infrastructure, with highlights of research at Binghamton University. Particular attention will be given to the transition from air cooling to single-phase direct liquid cooling, where cold plates bring the coolant close to high-power processors and other critical components. Direct liquid cooling can provide substantially greater heat-removal capability than air cooling while reducing fan power and enabling higher rack densities. However, increasing chip heat flux, localized hotspots, HBM integration, chiplets, and three-dimensional packaging are creating additional challenges at the package-to-coolant interface.
As heat fluxes and rack power densities continue to increase, two-phase liquid cooling becomes increasingly attractive. By utilizing the latent heat associated with phase change, two-phase systems can potentially remove very high heat fluxes while maintaining relatively uniform component temperatures and reducing coolant flow requirements. Technologies including two-phase cold plates, dielectric immersion cooling, and refrigerant-based approaches will be discussed, together with challenges involving flow stability, pressure control, critical heat flux, materials compatibility, reliability, and system integration.
The presentation will connect thermal challenges across the hierarchy from the chip and package to the server, rack, and data center, and will consider the growing interaction between thermal management, power delivery, advanced packaging, and facility infrastructure. Looking forward, thermal management will no longer simply respond to the power generated by computing hardware. Increasingly, the available cooling technology will help determine how much computing power can be packaged into a chip, server, rack, and ultimately an AI data center. Advanced single- and two-phase liquid cooling will therefore be key enabling technologies for the performance, density, energy efficiency, and sustainability of future AI computing systems.

Plenary Title: Wetting Phenomena in Nanoscale Spaces
Abstract: Wetting and capillary-driven transport in confined spaces play essential roles in a wide range of engineering systems, from nanoimprint lithography and advanced manufacturing to micro/nanofluidic devices and thermal management technologies such as heat pipes. As characteristic dimensions decrease to the nanometer scale, however, liquid transport can no longer be understood simply as a scaled-down version of macroscopic wetting and capillary flow. Confinement enhances the relative importance of solid-liquid interactions and introduces additional phenomena such as changes in molecular mobility, gas entrapment, and capillary condensation. In this talk, nanoscale wetting will be discussed through real-time observations of liquid invasion into nanochannels with depths on the order of tens of nanometers. Experiments with photocurable liquids reveal highly nonuniform wetting accompanied by the formation of numerous nanoscale bubbles. More importantly, as the channel depth decreases, the observed wetting dynamics deviate significantly from predictions based on conventional capillary-flow models. These observations suggest that nanoscale wetting is governed by the coupled effects of capillary forces, interfacial interactions, confinement-induced changes in liquid dynamics, gas behavior, and condensation.
These findings will be discussed not only in the context of nanoimprint lithography, where rapid and defect-free filling of nanoscale cavities is critical, but also from a broader perspective of liquid transport in confined geometries. Understanding how wetting and capillary transport change under nanoscale confinement may provide a common physical framework for designing next-generation manufacturing processes, micro/nanofluidic systems, and thermal management devices in which capillary transport governs liquid supply and heat-transfer performance.
