Self-assembly mechanism

Flexibility of pattern formation may well be the consequence of self-assembly mechanisms acting upon digital information such as that... 

In the near future, we wish to extend kinetics experiments to other synthesis of mesoporous materials, in order to determine how the self-assembly mechanisms are changing with respect to the type of synthesis. 

The self-assembly mechanism proposed for these spherical and cylindrical polymer backbones surrounded with quasi-equivalent dendritic coats is outlined in Figure 12.9. This knowledge allows the rational design of polymers with well defined spherical and cylindrical shapes. Quasi-equivalent character of these...

For example, if fresh POPC from a methanol solution is added to a POPC hposome solution, there will be an immediate formation of fresh liposomes. In fact, the cmc in this case is of the order of 10 ° in favor of the aggregates over the free monomers, and the rate of formation is correspondingly extremely high. Thus, we are in the presence of an independent self-assembly mechanism. 

Another parameter which plays a role in the self-assembly mechanism is the pre-hydrolysis step present in preparation B. This procedure involved the addition of ethanol to the two precursors (EtOH/Si = 1 1) before reaction with the CTAB solution. We have thus investigated the role that ethanol could play in the organization of the final samples.

More complicated alkaloid structures like stephacidine B exhibiting the impressive number of 15 rings and 9 stereogenic centres may have originated by spontaneous, not enzyme-catalysed dimerisation of avrainvillamide. The efficient bio-mimetic conversion of the precursor molecule avrainvillamide into its dimer stephacidine B under diverse experimental conditions by two Michael additions and additionally the retro-dimerisation of the dimer would support a self-assembly mechanism for formation of the dimer B [153-155]. 

A desire to design high capacity adsorbents resulted in the synthesis of hybrid materials with multifunctional groups introduced via direct co-condensation of proper organosilanes instead of less effective post-synthesis si lanization.19,20 One-pot synthesis through self-assembly mechanism allows the creation of active sites inside mesopores, that after template removal become accessible for adsorption.21 An alternative method for chemical grafting of OMSs, known as template displacement synthesis, permits a simultaneous template removal and attachment of functional groups.22...
