We synthesized and evaluated biodegradable and elastomeric polyesters (poly(glycerol sebacate) (PGS)) using polycondensation between glycerol and sebacic acid to form a cross-linked network structure without using exogenous catalysts. Synthesized materials possess good mechanical properties, elasticity, and surface erosion biodegradation behavior. The tensile strength of the PGS was as high as ...

Introduction Poly (ethylene glycol, PEG) based macromers have been widely used in tissue engineering applications as hydrogel type biomaterials, mainly due to their well known hydrophilicity and biocompatibility [1,2]. In addition, PEG based biodegradable hydrogels have been reported [3] and have drawn more attraction for tissue engineering scaffolds and/or drug delivery systems [4,5]. However,...

Cinnamyl long chain aroma esters were prepared by using the conventional and microwave-assisted methods. The esterification reaction of naturally occurring 3-phenyl-prop-2-en-1-ol and different chain lengths acidic and diol reagents was carried out at the temperature of 140 °C under solvent free conditions. As acidic reagents, oxolane-2,5-dione, oxane-2,6-dione, hexanedioic acid and decanedioic...

The synthesized bio-based copolyesters described in this paper bring added value the field of sustainable food packaging.

We developed a simple way to prepare smart silver nanoparticles that are well dispersible in both polar and nonpolar media. The synthesis was performed using solutions of an invertible amphiphilic polyester made via a polycondensation reaction of sebacic acid and poly(ethylene glycol). Reduction, formation of silver nanoparticles, and their stabilization occur in the polyester micellar domains ...

The aromatization of 2-octanol derived from castor oil as a byproduct in the formation of sebacic acid was investigated on various zeolite catalysts. Zn ion-exchanged MFI (ZSM-5) zeolites with small silica/alumina ratios and zinc contents of 0.5 to 2.0 wt. % were determined to exhibit good and stable activity for the reaction at 623 to 823 K. The yield of aromatics was 62% at 773 K and the spac...

ABSTRACT. Nano hydroxyapatite (n-HAp) and its composites have shown a great development in the field of tissue regeneration controlled drug delivery due to good biocompatibility bioactivity behavior. Furthermore, HAp-based nanocomposites enhance mechanical properties. These synthetic HAp can also be tailored fabricate scaffold with porosity which facilitate growth cell engineering. In this pape...
