Summary: In the last two decades, a lot of progress has been made in Nanotechnology and Nanoscience, an exploitation of matter on atomic, molecular and supermolecular
At low weld pressure, similar supermolecular
structure in the weld area and bulk material can be observed both for unreinforced and reinforced POM.
Meijer, A modular and supermolecular
approach to bioactive scaffolds for tissue engineering, Nat Mater.
By forming intramolecular and intermolecular hydrogen bonds between OH groups within the same cellulose chain and the surrounding cellulose chains the chains tend to be arranged parallel and form a crystalline supermolecular
This could be a boon to supermolecular
chemists using DNA to build nano-structured materials for drug delivery and other applications.
The idea is that an understanding of the basic chemistry, supermolecular
assembly of block and graft polymers, and microscopic fracture mechanisms will allow chemists to derive macroscopic behavior and thus select the most suitable polymer for a given application.
Over the past decade we have demonstrated some of the most bioactive materials ever reported by making supermolecular
polymers and giving them structures that can signal cells," Stupp said.
The National Nanotechnology Initiative (NNI) advocates a strict definition of nanotechnology by "including only activities at the atomic, molecular, and supermolecular
levels, in the length scale of approximately 1--100 nm range that create materials, devices, and systems with fundamentally new properties and function because of their small structure" (Holley, 2009, p.
Specific topics include controlled release and materials conversion using nanostructured supermolecules, supermolecular
systems based on dielectric elastomer actuators for biomimetic and biomedical applications, optical properties of self-assembled colloidal photonic crystals doped with citrate-capped gold nanoparticles, tuneable micro- and nano-periodic structures in urethane/urea networks, biomimetic apatite coatings, mimicking biomineralization processes, molecular engineering of phenyleneethynylenes towards specific molecular and supramolecular organization for optoelectronics, microstructural influence on flexure strength of a ceromer reinforced by polyethylene and glass fibers, and fundamentals of the nanocrystal formation from supersaturated solutions.
Despite its simple molecular structure, cellulose shows a large complexity and variability in its supermolecular
arrangement in cellulose fibrils.
Companies involved are the French Soufflet and Maguin firms, working together with biochemists of the Institute of Science and Supermolecular
Engineering in Strasbourg.
Finally, they can be classified based on the physical structure of the networks as amorphous, semicrystalline, hydrogen-bonded structures, supermolecular
structures and hydrocolloidal aggregates.
