Self-replication process control

The matrix properties of RNA make the self-replication process easier. RNA matrices are able to control the synthesis of complementary oligonucleotides. 

Figure 4 Kinetic analysis of the self-replication process of Ti. The graphs present the production of Ti over time from Ei and Ni initially seeded with the indicated concentrations of Ti. In the control experiment, the production of Ti in the tonplate-free reaction, shown in gray, was followed for comparison and also presented in the inset to anphasize the amplified growth of Ti over longer time.

Examples of dense silica, hybrid silica, metal oxides, solid-state metal oxide solutions, or colloidal self-assembly are unlimited. However, the recent developments to accurately control processing conditions (e.g., atmosphere, temperature, and motion) led to films with unique properties (see Figure 9.6) [52,53]. These progresses concern mesoporous coatings with controlled pore size and structure [26], hard template infiltration and/or replication [54-58], nanostructured epitaxial low-quartz thin films [59], ultrathin nanostructured supported networks [60,61], ultrathick porous Ti02 layer prepared from aqueous solutions [51], coatings with hierarchical porosity [62], multilayer porous stacks [63], colloidal MOF layers [64,65], pillar planar nanochannels (PPNs) for nanofluidics [66], and so on.
