Nanoporous stabilizers

A dendrimer has a better-defined shape than ordinary polymers or surfactants and possesses dynamic inner cavities. That makes them capable of encapsulating of guests and acting as nanoreactors and nanoporous stabilizers [2,17],...

In the second area, improvements to the thermal and mechanical stability of nanoporous materials from ordered block copolymers should be targeted. To expand the application base for these materials, high temperature stability is a key requirement. For example, in templating applications that require elevated processing temperatures in either thin films or monolithic materials... 

It is obvious that the change in stability upon UPD of Cu and Ag (Figure 5.15) can be harnessed for manipulation of SAMs, as demonstrated by the scheme of Figure 5.20a where nanopores were created in a sequence of steps involving UPD of both Ag and Cu as well as reductive desorption and adsorption of thiols [219,220].

The number of papers dealing with catalysis by Au was more or less than 5 a year in the 1980s but reached 700 in 2005 and 600 in 2006. There are three major streams in current research activities on Au catalysts expansion of applications, especially to liquid-phase organic reactions [4], discussion on the active states of Au [5], and exploration of new forms of Au catalysts. The last stream has emerged recently and is represented by Au submicron tube [6], nanoporous Au [7, 8], polymer stabilized Au colloids [9] and Au on solid polymers [10, 11], which in turn provide valuable information for determining what states of Au are surprisingly active and selective.

In the case of alkane cracking, dispersion forces between the alkane molecules and the siliceous walls of the zeolites and perhaps other nanoporous crystalline and ordered materials are possibly the most important interactions for stabilizing adsorption in the cavities, since the proton affinity of alkanes is low [104] and the electrostatic interactions between the alkane and the adsorbent are negligible [97],...
