[ 1 ] - Denture base polymers, poly methyl methacrylate improved using free radical copolymerization
Poly methyl methacrylate (PMMA) is the most common material used in Prosthodontics. Several studies indicate a breakdown of the number of very high resin bases after 2 to 3 years to avoid breaking bass and several attempts have been made, such as altering the chemical structure of resin by adding causes cross linking or copolymerization. The innovative method for improving the physical properti...
[ 2 ] - Synthesis and characterization of supramolecule self-assembly polyamidoamine (PAMAM) G1-G1 NH2, CO2H end group Megamer
Supramolecule self assembly polyamidoamine (PAMAM) dendrimer refers to the chemical systems made up of a discrete number of assembled molecular subunits or components. These strategies involve the covalent assembly of hierarchical components reactive monomers, branch cells or dendrons around atomic or molecular cores according to divergent/convergent dendritic branching principles, systematic f...
[ 3 ] - Synthesis and characterization of termini azobenzene dendrimer
Some organic molecules can be isomerized upon photoirradiation and when accompanied by a change in the visible absorption spectrum, it is called photochromism. Azobenzenes are important part of molecular machines and nanotechnology, Which are This phenomenon is called photoisomerization Azobenzene (azo) chromophores , and have been incorporated into a wide variety of materials and molecular arc...
[ 4 ] - Theoretical models for determination of weight percent of PHCS-g-PLLA co polymer using experimental data
The amphiphilic graft copolymer using chitosan (CS) as hydrophilic segment and poly (L-lactic acid) (PLLA) as hydrophobic segment, was prepared through a protection-graft-de protection route. Chitosan is a polysaccharide comprising of copolymers of glucosamine and N-acetyl glucosamine. Chitosan is the deacetylated derivative of chitin, which is one of the most abundant natural polysaccharides c...
