Silicon size selection

An additional way to effect the shape/size selectivity of zeolite catalysts was developed which entailed deposition of various silicon-containing deposits on the external surfaces of zeolites to create an additional diffusion barrier [131, 138].

Potential applications of a size-selective assembly process may require a multipartide pattern to be integrated on substrates other than the PDMS template used here for the assembly. To accommodate that requirement, microcontact printing was used to transfer multipartide arrays to a silicon model surface.l l Figure 4b shows a detail of a multipartide pattern printed on a plain silicon surface. Inspection of the assembly template after printing confirmed high transfer yidd across the entire 250 pm x 250 pm large array area, leading to... 

Experimental details—The measurements of XPS spectra of supported cluster materials (Sect. 5.1.2) were performed on different samples. For comparing different sizes particular samples were prepared, by deposition of size-selected clusters on silicon wafers pieces (8 x 15 mm).
