Au capping agent removal using plasma at mild temperature
To prevent sintering, ozone treatment at mild temperature is used to remove the capping agent from supported Au nanoparticles. The Au nanoparticles are first synthesized as a colloidal solution and then supported on alumina. Fourier Transform Infra Red (FTIR) shows the capping ag ...

Towards high resolution operando electron microscopy of a working catalyst
Doctoral thesis (2016) - I. Puspitasari (author)
The objectives of this PhD project are to address the challenges of in-situ TEM and introduce a new generation of in-situ TEM equipment. In Chapter 2 the in-situ TEM facilities are introduced, focusing on the nanoreactor that has gone through quite some development stages during ...
