Recent Advancements in 3D Printing and Bioprinting Methods for Cardiovascular Tissue Engineering.

Recent decades have seen a plethora of regenerating new tissues in order to treat a multitude of cardiovascular diseases. Autografts, xenografts and bioengineered extracellular matrices have been employed in this endeavor. However, current limitations of xenografts and exogenous scaffolds to acquire sustainable cell viability, anti-inflammatory and non-cytotoxic effects with anti-thrombogenic properties underline the requirement for alternative bioengineered scaffolds.

Experimental and Prediction Study of Displacement-Rate Effects on Flexural Behaviour in Nano and Micro TiO Particles-Epoxy Resin Composites.

Epoxy resin composites with different weight fractions of TiO microparticles (1%, 5%, 10%, 15%, 20%) and of TiO nanoparticles (0.5%, 1%, 2%, 3%) were prepared. The particle size of the nanoparticles was averaged around 21 nm while the particle size of the micro TiO particles was averaged around 0.
