    Facile, fast, and inexpensive synthesis of monodisperse amorphous Nickel-Phosphide nanoparticles of predefined size
    (Cambridge : Royal Society of Chemistry, 2011) Arzt, Eduard; Moh, Karsten; Cavelius, Christian; Mandel, Karl; Dillon, Frank; Koos, Antal A.; Aslam, Zabeada; Jurkschat, Kerstin; Cullen, Frank; Crossley, Alison; Bishop, Hugh; Grobert, Nicole
    Monodisperse, size-controlled Niā€“P nanoparticles were synthesised in a single step process using triphenyl-phosphane (TPP), oleylamine (OA), and Ni(II)acetyl-acetonate. The nanoparticles were amorphous, contained 30 at% P and their size was controlled between 7ā€“21 nm simply by varying the amount of TPP. They are catalytically active for tailored carbon nanotube growth.

    Get more out of your data: A new approach to agglomeration and aggregation studies using nanoparticle impact experiments
    (Hoboken, NJ : Wiley, 2013) Ellison, Joanna; Tschulik, Kristina; Stuart, Emma J.E.; Jurkschat, Kerstin; OmanoviĀ“c, Dario; Uhlemann, Margitta; Crossley, Alison; Compton, Richard G.
    Anodic particle coloumetry is used to size silver nanoparticles impacting a carbon microelectrode in a potassium chloride/citrate solution. Besides their size, their agglomeration state in solution is also investigated solely by electrochemical means and subsequent data analysis. Validation of this new approach to nanoparticle agglomeration studies is performed by comparison with the results of a commercially available nanoparticle tracking analysis system, which shows excellent agreement. Moreover, it is demonstrated that the electrochemical technique has the advantage of directly yielding the number of atoms per impacting nanoparticle irrespective of its shape. This is not true for the optical nanoparticle tracking system, which requires a correction for the nonspherical shape of agglomerated nanoparticles to derive reasonable information on the agglomeration state.
