IMG Seminar Series: Tips for Effective Oral Presentations and The Ins and Outs of the IMG Website

Event date: 
Fri, 10/02/2015 - 4:00pm
Dr. David Arnold will give a talk entitled "Tips for Effective Oral Presentation," where he will discuss best practices for delivering high-quality oral presentations, including planning, oral delivery, and graphics.  "Do’s and Don’ts” will be highlighted along with a number of practical suggestions and personal experiences.
 
Nicolas Garraud and Jason June will give an overview of the IMG website, highlighting the different functions, various content types and how to add content to the webpage and wiki.

Modeling of the Magnetic Particle Imaging Signal Due to Magnetic Nanoparticles

Magnetic Particle Imaging (MPI) is a new tomographic imaging technique that maps the spatial distribution of iron oxide magnetic nanoparticles (MNPs) in real time and with spatial resolution that is on par or better than other biomedical imaging techniques. In this project, we will develop a theoretical foundation relating the properties of MNPs and MPI magnetic field conditions to the MPI signal strength and resolution. These efforts will yield design rules that will guide the rational design of future generations of MNP tracers for MPI. The proposed research will enable development of a novel biomedical imaging technique capable of high resolution real time imaging using nontoxic tracers suitable for a variety of biomedical applications.

IMG Faculty Help Launch the NSF MIST Center

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)
