Synthesis of Ferrofluids

Posted by ROSHAN CHANDRA on February 4, 2011 at 12:28pm in NanoResearch

Hullo Everybody,

 

I am currently working in the area of ferrofluids for enhanced thermal conductivity. The synthesized ferrofluid is not stable even after adding stabilizers. 

If anyone has any experience in the synthesis of ferrofluids, kindly let me know the solution to the problem stated above. I have also carried out the zeta potential studies but no satisfying results has been obtained till now. 

Awaiting a positive response from the members of nanopaprika community. 

 

Cheers!!!

    Which stabilisers you are using at %

    Which place r u working

      Hullo Shiva,

      I am using acetic acid and citric acid as stabilizers for 1%, 2.5% PVA FF, 3% GELATIN FF, 0.05 M GLYCINE FF AND 0.01% BSA FF.

    Dear Roshan

    This very recent open access paper might be helpful through.

    Hi,

    There is a team in Romania highly specialized in the development of ferrofluids and magnetic nanofluids:

     

    Laboratory of Magnetic Fluids Centre of Fundamental and Advanced Technical Research, Romanian Academy,Timisoara Division, Timisoara, Romania

     

    Professors Doina Bica (now deceased) and Prof. Landislau Vekas have an extensive body of work on the subject. Maybe you can find help in their published work.

     

    You may check the following presentation to start with:

    Good luck in your work,

    Paulo

      Hullo Paulo,

       

      Thank you so much for your timely reply. May i know your research interests?

       

      Cheers!!!!!!!!!!!
