Nanomagnetism: Seminar at the Waterloo Institute of Nanotechnology

In May 2016 I presented a seminar at the Waterloo Institute of Nanotechnology (WIN). The whole seminar can be seen HERE.  

Interview to Rhonda Broussard: One Good Question

One Good Question This post is part of a series of interviews with international educators, policy makers, and leaders titled “One Good Question.”  These interviews provide answers to my One Good Question (outlined in About) and uncover new questions about education’s impact on the future.

RSC Advances: Unusual magnetic damping effect in a silver–cobalt ferrite hetero nano-system

The static and dynamic magnetic response of the newly synthesized CoFe2O4–Ag hetero nano-system showed significant enhancement in the effective energy barrier and reduction of the magnetic hardness of CoFe2O4 upon interaction with non-magnetic Ag as compared to neat CoFe2O4. The observed magnetic properties of CoFe2O4–Ag have been dissected in detail using the superparamagnetic Stoner–Wohlfarth and …

Compact Ag@Fe3O4 Core-shell Nanoparticles by Means of Single-step Thermal Decomposition Reaction

Figure 1

A temperature pause introduced in a simple single-step thermal decomposition of iron, with the presence of silver seeds formed in the same reaction mixture, gives rise to novel compact heterostructures: brick-like Ag@Fe3O4 core-shell nanoparticles. This novel method is relatively easy to implement, and could contribute to overcome the challenge of obtaining a multifunctional heteroparticle in …
