“…We observed a similarly decreased tensile stress at break when increasing the filler content. It has been reported that the combination of hydrophobic bulk polymer and hydrophilic fillers leads to improper interface bonding, as observed in our study (Goda et al, 2013). Further work could focus on different surface modifications like particle roughness, size, and chemistry as well as bulk polymer chemistry to achieve an increased polymer/filler interface binding (Boccaccini et al, 2002(Boccaccini et al, , 2010Goda et al, 2013).…”

Critical size bone defects are regularly treated by auto-and allograft transplantation. However, such treatments require to harvest bone from patient donor sites, with often limited tissue availability or risk of donor site morbidity. Not requiring bone donation, three-dimensionally (3D) printed implants and biomaterial-based tissue engineering (TE) strategies promise to be the next generation therapies for bone regeneration. We present here polylactic acid (PLA)-bioactive glass (BG) composite scaffolds manufactured by fused deposition modeling (FDM), involving the fabrication of PLA-BG composite filaments which are used to 3D print controlled open-porous and osteoinductive scaffolds. We demonstrated the printability of PLA-BG filaments as well as the bioactivity and cytocompatibility of PLA-BG scaffolds using pre-osteoblast MC3T3E1 cells. Gene expression analyses indicated the beneficial impact of BG inclusions in FDM scaffolds regarding osteoinduction, as BG inclusions lead to increased osteogenic differentiation of human adipose-derived stem cells in comparison to pristine PLA. Our findings confirm that FDM is a convenient additive manufacturing technology to develop PLA-BG composite scaffolds suitable for bone tissue engineering.

“…Matriks polimer yang sering digunakan adalah polyester, vinyl ester, epoksi, poliamida, dan lain lain. Komposit dengan matriks polimer memiliki kelebihan yaitu ringan, kekuatan baik, dapat mengikuti bentuk, dapat diproduksi misal dengan biaya yang relative lebih murah (Goda, Sreekala, Malhotra, Joseph, & Thomas, 2013).…”

In this research, preparation of natural matrix from modified flea secretion (SKL) by the addition of adipic acid as matrix in biocomposites of ramie fiber have been carried out. This research was initiated by dissolving the chunks of flea secretion using ethanol with ratio 1:2 and heated at temperature 50oC. Flea secretion has modified by the addition of adipic acid in various concentration 5%, 10%, 15%, 20%, and 25%. Viscometry technique with viscometer ostwald was used for characterizing intrinsic viscosityof natural matrix. The optimum value of intrinsic viscosity were reached at concentration 5% of adipic acid that has 77,08 mg/l viscosity. Biocomposites were made by mixing ramie fibers and natural matrix SKL which have been modified by the addition of adipic acid with optimum concentration at 60:40ratio of fibers: matrix. Biocomposites were evaluated for mechanical properties with ASTM D638 type IV standard. Biocomposite sampel was formed specimens and tested with tensile tester. Biocomposite from ramie fibers and natural matrix SKL modified by adipic acid has a tensile strength 15,14 MPa and elastic modulus was 1519,15 MPa.

Herewith we report a facile synthesis of zinc oxide doped with (5, 10, 15, and 20 wt%) titanium oxide nanocomposites in gelatin under ultra-sonication. The X-ray diffraction (XRD) data revealed ZnO the formation in addition to a rutile phase TiO2. The ZnO phase size decreased, and the rutile TiO2 phase increased with a TiO2 loading increment. The scanning electron microscopy (SEM) displayed a combination of spherical and hexagonal particles with a 60 – 80 nm size distribution. The prepared nanostructures photocatalytic activity was assisted using Rhodamine B dye, where they showed enhanced photodegradation competence under visible light irradiation. The kinetics of photodegradation followed the first-order kinetics with the 20 % wt sample having the maximum activity. The mechanistic investigation revealed the dominance of h+ and •O2- species during the dye photodegradation. The results indicate the potential application of such gelatin stabilized nanostructures for dye illumination from aqueous solutions under sunlight.
