Graphene Derivatives in Biopolymer-Based Composites for Food Packaging Applications.

This review aims to showcase the current use of graphene derivatives, graphene-based nanomaterials in particular, in biopolymer-based composites for food packaging applications. A brief introduction regarding the valuable attributes of available and emergent bioplastic materials is made so that their contributions to the packaging field can be understood. Furthermore, their drawbacks are also disclosed to highlight the benefits that graphene derivatives can bring to bio-based formulations, from physicochemical to mechanical, barrier, and functional properties as antioxidant activity or electrical conductivity.

Toxic impacts of rutile titanium dioxide in Mytilus galloprovincialis exposed to warming conditions.

Climate change is leading to a gradual increase in the ocean temperature, which can cause physiological and biochemical impairments in aquatic organisms. Along with the environmental changes, the presence of emerging pollutants such as titanium dioxide (TiO) in marine coastal systems has also been a topic of concern, especially considering the interactive effects that both factors may present to inhabiting organisms. In the present study, it has been assessed the effects of the presence in water of particles of rutile, the most common polymorph of TiO, in Mytilus galloprovincialis, under actual and predicted warming conditions.

Biochemical and histopathological impacts of rutile and anatase (TiO forms) in Mytilus galloprovincialis.

Titanium dioxide (TiO) particles have been widely used in various industrial applications and consumer products. Due to their large production and use, they will eventually enter into aquatic environments. Once in the aquatic environment TiO particles may interact with the organisms and induce toxic effects.
