The National Science Foundation awarded $171,218 under the Engineering (47.041) federal grant program to the Research Foundation of the City University of New York for a project titled "Understanding the Dynamic and Thermal Behaviors of Colloidal Droplets Toward a Novel Freezing-Based Inkjet Printing Concept." The objectives of the project are to characterize the dynamic behaviors and thermal evolutions of colloidal droplets during impact, deformation, and freezing processes under different ambient and surface conditions. The project will also examine deposit morphologies with varying temperature and humidity conditions. This research seeks to advance understanding of the dynamic and thermal behaviors of colloidal droplets in a novel freezing-based inkjet 3D printing technique to fabricate high-quality functional structures for applications in aerospace, healthcare, automotive, and other industries. The award period is from October 1, 2022 through May 31, 2024.
