Nanoarchitecture

By all accounts, the hypothesis of formation of DNA+adamantane+amino acid nanoarchitectures is currently immature and amenable to many technical modifications. Advancement in this subject requires a challenging combination of state-of-the-art approaches of organic chemistry, biochemistry, proteomics, and surface science.

Polyhedral oligomeric silsesquioxane (POSS) has been extensively studied as starting substrate to construct nanocomposites with precise control of nanoarchitecture and properties. Octahedral derivatives are the most representative ones of this family. It was reported that the HRP-catalyzed conjugation of catechin on amine-substituted octahedral silsesquioxane amplified the beneficial physiological property of flavonoids. The POSS-catechin conjugate exhibited great...

Due to the rising interest in supramolecular structures and nanoarchitectures, as well as their broad applicability, including the field of combinatorial chemistry, iterative strategies will gain more and more importance in preparative organic chemistry [60].

A general issue is that these nanocarbons are often only discussed in terms of a class of materials based on their shape (CNT, etc.). However, the growing understanding of these materials [16,33], of their controlled synthesis [34], and of the interfacial phenomena during interaction between nanocarbons and semiconductor particles [1,6,8,23,35] has clearly indicated that in addition to the relevant role given from the possibility to tune nanoarchitecture (and related influence on mass and charge transport, as well as on microenvironment [36]) the specific nanocarbon characteristics, surface chemistry and presence of defect sites determine the properties.

Jeffrey Long (left) was born in Great Falls, Montana in 1970, but he spent most of his early years in Winston-Salem, NC. He received a B.S. in Chemistry with Honors from Wake Forest University in 1992. Working with Prof. Royce Murray, he earned a Ph.D. in Chemistry from the University of North Carolina at Chapel Hill in 1997. His research focuses on nanostructured materials, particularly hybrid nanoarchitectures for applications in sensing, separations, and electrochemical energy storage and conversion.

Three-dimensional electrode nanoarchitectures exhibit unique structural features, in the guise of amplified surface area and the extensive intermingling of electrode and electrolyte phases over small length scales. The physical consequences of this type of electrode architecture have already been discussed, and the key components include (i) minimized solid-state transport distances (ii) effective mass transport of necessary electroreactants to the large surface-to-volume electrode and (iii) magnified surface—and surface defect—character of the electrochemical behavior. This new terrain demands a more deliberate evaluation of the electrochemical properties inherent therein.
