The microbial production of L-(+)-lactic acid is rapidly expanding to allow increased production of polylactic acid (PLA), a renewable, biodegradable plastic. The physical properties of PLA can be tailored for specific applications by controlling the ratio of L-(+) and D-(-) isomers. For most uses of PLA, the L-(+) isomer is more abundant. As an approach to reduce costs associated with biocatal...

The aim of this study was to develop a solvent-free polylactic acid (PLA) open-cell porous scaffold for bone tissue engineering using compression molding and new chemical foaming compound, that we named CFCO. latter is composed blend PLA azodicarbonamide (ADA) as agent, with the addition chitosan-grafted (CS-g-PLA) copolymer at various concentrations. novelty approach during foaming, is, decomp...

This paper deals with the study of degradation polylactic acid (PLA) material structures and biocomposite systems a PLA matrix containing ground natural particulate waste fillers, buckwheat husks egg shells. Waste fillers were used without difficult cleaning operations to describe effect raw on PLA. Biocomposites materials are increasingly coming forefront in car interiors packaging products. T...

In recent years, the composite nanomaterials area has had a great development impact in health sciences. Biomaterials depict as one of most promising since they are compatible with additive manufacturing (AM) techniques. It is also possible to use them mold specific medical parts. Composite have shown good biocompatibility and low toxicity benefits equal or greater than metals (i.e., Co-Cr allo...
