Polymeric fractals and the unique treatment of polymers
نویسنده
چکیده
2014 It has been suggested that r-fractals allow a uniform description of arbitrarily connected polymers. r is the exponent of the maximal possible radius of gyration, i.e. R ~ Nr. We conjecture that 1/r is identical with the spectral dimension of the polymeric fractal. Tome 49 N° 9 SEPTEMBRE 1988 LE JOURNAL DE PHYSIQUE J. Phys.

The theta-point and critical point of polymeric fractals : a step beyond Flory approximation
We propose a new form of free energy for polymeric fractals (chain-like, branched or membranes) based on self-similarity arguments and on the existence of a maximum gyration radius. Results are obtained conceming the size exponents at the theta-point and critical point. These two exponents depend on a single parameter only, for which a simple phenomenological expression is provided. A very good...
متن کاملNimodipine-Loaded Pluronic Block Copolymer Micelles: Preparation, Characterization, In Vitro and In Vivo Studies
Nimodipine (NM), as a lipophilic calcium channel blocker indicated for the prevention and treatment of neurological disorders, suffers from an extensive first pass metabolism, resulting in low oral bioavailability. Polymeric micelles, self-assembled from amphiphilic polymers, have a core-shell structure which makes them unique nano-carriers with excellent performance as drug delivery. This inve...

Antenna Miniaturization Using Fractals Richa Garg, AP ECE Deptt., [email protected], J.C.D.C.O.E., Sirsa ABSTRACTThe use of fractal geometry in designing antenna has been a resent topic of interest. Fractal shape has their own unique characteristics that the improved antenna performance can be achieved without degrading the antenna properties. Modern telecommunication system requires antenn...
متن کاملPotential of polymeric particles as future vaccine delivery systems/adjuvants for parenteral and non-parenteral immunization against tuberculosis: A systematic review
Objective(s): Production of effective tuberculosis (TB) vaccine is necessity. However, the development of new subunit vaccines is faced with concerns about their weak immunogenicity. To overcome such problems, polymers-based vaccine delivery systems have been proposed to be used via various routes. The purpose of this study was to determine the potential of polymeric particles as future vaccine...
