Magnetization relaxation times in nanoparticles: the role of applied field strength

Karen Livesey

Department of Physics, University of Colorado at Colorado Springs

 

I will discuss an overview of magnetization relaxation times, and the resulting interpretation of magnetization-versus-temperature (M vs. T) measurements, of nanoparticle systems. Our recent analytic work to fit these curves is discussed. If there is time, I will discuss current problems with including the role of applied magnetic field strength in the relaxation times, and our attempts to overcome these.

 

Functional Materials: Nanoparticles – Synthesis and Characterization

Angelika Kmita

AGH University of Science and Technology

Academic Centre for Materials and Nanotechnology, Krakow, Poland

Introduction to particle synthesis and characterization will cover:

• Basic methods for obtaining nanoparticles: including “top-down” and “bottom-up” approach.
• The advantages and disadvantages of the presented methods.
• Discussion of research results using as an example zinc ferrite nanoparticles synthesized via co-precipitation method or via thermal decomposition of organometallic compounds.
• Characterization of nanoparticles with particular emphasis on spectroscopic methods.

 

Functionalized magnetic nanoparticles for biomedical application

Dorota Lachowicz

Introduction to functionalized magnetic nanoparticles for biomedical application will address the following issues:

• Magnetic nanoparticles in biomedical applications 
• From design and synthesis to real biomedical applications - problems and challenges
• Basic methods of surface functionalization of magnetic nanoparticles
• Examples of systems of functionalized magnetic nanoparticles obtained in our team - physicochemical properties of the obtained systems

 

Polymer scaffolds as templates for synthesis of magnetic nanoparticles

Samuel D. Oberdick,

National Institute of Standards and Technology, Boulder, CO

Iron oxide nanoparticles are often synthesized using coprecipitation because the technique is low-cost, straightforward and environmentally friendly. Unfortunately, the synthesis offers limited control over the final diameter of nanoparticles. Size control can be improved by growing the particles within the pores of a polymer scaffold. The final diameter of particles can be tuned by adjusting the molecular weight of polymer and can be used to synthesize particles smaller than 5 nanometers.
