Dear Abierbans, I think you have a valid point about surfactants preventing agglomeration of ferro-particles and so, I think that section should be changed a bit. Before deleting some of the text that emphasized Brownian motion, I considered that a large surface area ball of miceles around a ferroparticle would get bumped around more frequently and this could help to keep the particle in suspension. Or perhaps the impacts would all get averaged out: more impacts but from opposing/self canceling directions? I don't know enough about Brownian motion to know. I considered surfactant action in terms of micels and I thought I understood the whole story, but, I don't understand how nanospheres of soy lecithin could prevent agglomeration of ferroparticles. I made some changes to this section, feel free to re-edit if you think I've missed something.

Best regards, Electricmic

Hi, happy 2008!!

I tried to rewrite the para- story pretty extensively and I'd appreciate some review. Jcwf (talk) 01:17, 1 January 2008 (UTC)Reply
