The NSF Multi-functional Integrated System Technology Center (MIST Center) held it’s Kickoff Meeting on Dec. 11-12, 2014. Led by IMG faculty Dr. Nishida and Dr. Arnold, and in partnership with UCF, the mission of the MIST Center is to facilitate integration of novel materials, processes, devices, and circuits into multi-functional systems through research partnerships between university, industry, and government stakeholders. With inaugural membership from eight organizations, the MIST Center selected 8 projects (6 at UF and 2 at UCF) to be conducted during 2015. The UF projects are:

• Directed Nanoparticle Assembly by Electrophoretic Deposition (PI: Dr. Arnold)
• Laser Micromachining of 3-D Miniature Parts in Hard Materials (PI: Dr. Sheplak)
• Technology Development for Harsh Environment Microsensors (PI: Dr. Sheplak)
• High-Performance CoPt Micromagnets (PI: Dr. Arnold)
• Compact Array Antennas with High Gain, Power Efficiency, and EMI Immunity in a System-in-Package Platform (PI: Dr. Yoon)
• Ferroelectric HfO2 for Energy Storage and Non-volatile Memory Applications (PI: Dr. Nishida)

Daniel Blood, Rob Damitz and Erica Gonzaga, co-founders of aqUV, developed a portable water purification device that uses ultraviolet light to sterilize water were awarded $25,000 for winning the UF Big Idea Business Plan Competition.   More information can be found here.
