In previous works, we reported the fabrication of cotton-wool-like composites consisting of siloxane-doped vaterite and poly(l-lactic acid) (SiVPCs). Various irregularly shaped bone voids can be filled with the composite, which effectively supplies calcium and silicate ions, enhancing the bone formation by stimulating the cells. The composites, however, were brittle and showed an initial burst ...

In composite materials made of polymer matrices and micro-nano dispersed compartments, the morphology of the dispersed phase can strongly affect several features of the final material, including stability, loading efficiency, and kinetic release of the embedded molecules. Such a polymer matrix composite can be obtained through the consolidation of the continuous polymer phase of a water-in-oil ...

Poly(lactic acid) is biodegradable polymer derived from renewable resources and non-toxic, which has become most interested polymer to substitute petroleum-based polymer. However, it has low glass transition temperature and poor gas barrier properties to restrict the application on hot contents packaging and long-term food packaging. The objectives of this research are: (a) to reduce coagulatio...

In this work, the effects of Chicken egg shell powder (ESP) on properties Poly(Lactic Acid) PLA/ESP composite films (products) were examined. 4 wt.% PLA solution prepared and ESP added to at wt. %10, %20, %30, %50. by film-casting method. The mechanical thermal behaviours composites investigated using fourier transform infrared spectroscopy (FTIR), xray diffraction analysis (XRD), thermogravime...

The influence of the natural Gongura roselle fiber on tensile and flexural properties as well Shore D hardness acrylonitrile-butadiene-styrene (ABS) poly (lactic acid) (PLA) was investigated. composites were printed in fused deposition modeling (FDM) 3D technique. addition improved mechanical tested composites, while strength, modulus better case ABS-based composite. Whereas, PLA-based showed h...

in the present study lactic acid production was enhanced by optimizing the three process variables viz; inoculum size, temperature and ph using three factor five level ccrd (central composite rotatable design) by lactobacillus delbruckii under smf (submerged fermentation process). paneer (dairy by-product) whey was used as sole substrate for lactic acid production. design expert 8.0.2.0 softwar...
