In situ study on the wet chemical synthesis of nanoscopic Pt colloids by "reductive stabilization"

Article Abstract:

The synthesis of colloidal Pt particles obtained from the reaction between platinum acetylacetonate (Pt(acac)2) and Al(CH3)3 was analyzed. The formation of the Pt colloid namely, 'reductive stabilization' was established by a combination of techniques including NMR, anomalous small-angle X-ray scattering (ASAXS), X-ray absorption spectroscopy (XAS), density functional theory (DFT) computations, and transmission electron microscopy (TEM).

Soft X-ray to characterize polyelectrolyte assemblies

Article Abstract:

Transmission microscopy with soft X-rays (TXM) is used for imaging in-situ polyelectrolyte assemblies in aqueous environment. The method is found to be element specific, exhibiting a lateral resolution of 20 nm, and is coming up as a highly promising approach in colloid and polyelectrolyte science.
