Expansion of obturation materials to improve the seal of root-filled canals has been reported even for classic obturation materials. Gutta-percha expands in the presence of eugenol [ , ] which may help to reduce gaps within canals obturated with zinc oxide-eugenol sealer-filled canals caused by the release of eugenol from the set sealer.

Synthesis and gas transport properties of new aromatic 3F polymers Article in Journal of Membrane Science (2) October with 78 Reads How we measure 'reads'. Polymers containing the sulfonyl unit together with different functional groups (e.g. ether, sulfide, amide and ester) combine the peculiar features of each moiety in the same macromolecular polymers belong to different families at the same time (polysulfones, polyethers, polysulfides, etc.).They can be treated more properly as polysulfones when the SO 2 group plays a.

This paper focuses on a literature analysis and review of sulfonated polymer (s-Poly) composites, sulfonated organic, inorganic, and organic–inorganic hybrid membranes for polymer electrolyte membrane fuel cell (PEM) systems, particularly for methanol fuel cell applications.
In this review, we focused mainly on the detailed analysis of the distinct segment of s-Poly composites/organic&ndash Cited by: 1. Recent Developments in Polymer Macro, Micro and Nano Blends: Preparation and Characterisation discusses the various types of techniques that are currently used for the characterization of polymer-based macro, micro, and nano blends.
It summarizes recent technical research accomplishments, emphasizing a broad range of characterization methods. Introduction to polymers About this free course The raw materials for making the monomers had at first been based on coal tar derivatives but, with the rise of the petrochemical industry based on oil and natural gas, a much wider range of basic chemical building blocks became available.
Such relations can be a guide to synthesis of new. For the development of new free surfaces, extra energy is undoubtedly needed to conquer natural factors that raise this energy [87, 88].
The glass alteration range must be the temperature point among the balance solution and freezing solid, in a way that the enthalpies at each of those factors are well-known.
Chemical grafting of sulphonated monomers onto the hydrophobic polymer backbone is another approach that has been employed for the preparation of ion containing materials, such as the copolymer consisting of a polystyrene backbone and sodium styrene sulphonate graft chains (PS-g-macPSSNa) [, ] or a copolymer of sodium styrene sulphonate.

All synthesis methods can be employed to create general physical properties of graft copolymers. They can be used for materials that are impact resistant, and are often used as thermoplastics elastomers, compatibilizers or emulsifiers for the preparation of stable blends or alloys.
Objectives. New obturation biomaterials have been introduced over the past decade to improve the seal of the root canal system.
However, it is not clear whether they have really produced a three-dimensional impervious seal that is important for reducing diseases associated with root canal by: Biocomposite material that is especially suitable for bone surgical applications, containing: at least one bioceramic piece (1) (bioceramic component) and at least one material component (2).
The material component (2) comprises at least reinforcement elements which have been manufactured of essentially resorbable material like polymer, copolymer, polymer mixture and/or ceramic by: AbstractThis review presents the most important research on alternative polymer membranes with ionic groups attached, provides examples of materials with a well-defined chemical structure that are described in the literature.
Furthermore, it elaborates on the synthetic methods used for preparing PEMs, the current status of fuel cell technology and its by: 2.
