A recent publication in 'Gravitational and Space Research' highlights significant findings from research conducted through the ISS National Laboratory, focusing on transport phenomena - key processes that govern the movement of momentum, energy, and mass. These processes, such as heat transfer and diffusion, are fundamental to understanding how substances interact with their surroundings. By studying these dynamics in the microgravity environment of space, scientists are uncovering insights with potential applications in areas like pharmaceuticals and advanced manufacturing.

The ISS National Lab provides researchers with unique access to persistent microgravity conditions, enabling studies that are not feasible on Earth. Since 2016, in partnership with the U.S. National Science Foundation's (NSF) Chemical, Bioengineering, Environmental, and Transport Systems (CBET) Division, the ISS National Lab has supported 43 projects in diverse scientific fields. These projects include investigations into heat transfer, combustion, and fluid dynamics, advancing fundamental science and demonstrating the value of collaboration between federal agencies and space-based research platforms.

"This latest publication highlights ways researchers have leveraged microgravity to isolate and study fundamental physical phenomena typically obscured by gravity-induced forces," said Phillip Irace, lead author and science program director of research and innovation for the ISS National Lab.

"Our collaboration with NSF provides increased access to space to enable groundbreaking fundamental scientific research on the ISS in ways unattainable on Earth," Irace continued. "For instance, the absence of sedimentation in microgravity allows us to study how small particles move under the influence of temperature or surface tension gradients. These findings can advance applications such as drug delivery, biosensing, and thermal management technologies."

The paper describes several impactful experiments, including studies of spherical cool diffusion flames and investigations into fluid dynamics free from buoyant forces. "This research paves the way for potential advances in combustion engine efficiency, energy production, and materials manufacturing," explained Shawn Stephens, senior payload operations project manager for the ISS National Lab and a co-author of the paper.

"Our work on the ISS allows us to push the boundaries of science," Stephens added. "Completing these investigations has led to advancements that have the potential to significantly enhance various industries and improve life on Earth."
