Nanocomposites based on the graphene family for food packaging: historical perspective, preparation methods, and properties.

Nanotechnology experienced a great technological advance after the discovery of the graphene family (graphene - Gr, graphene oxide - GO, and reduced graphene oxide-rGO). Based on the excellent properties of these materials, it is possible to develop novel polymeric nanocomposites for several applications in our daily routine. One of the most prominent applications is for food packaging, offering nanocomposites with improved thermal, mechanical, anti-microbial, and barrier properties against gas and water vapor.

Graphitic Carbon Nitride-Based Materials as Catalysts for the Upgrading of Lignocellulosic Biomass-Derived Molecules.

The use of graphitic carbon nitride (g-CN)-based catalysts in the upgrading of lignocellulosic biomass significantly contributes to the greener production of biofuels, polymer precursors, and building blocks. In recent years, several catalysts based on g-CN have been developed and applied in both photocatalyzed and non-photocatalyzed (thermal) reactions. This Review provides an overview on the upgrading of lignocellulosic biomass deploying several compositions of g-CN-based catalysts.

Angelica Lactones: From Biomass-Derived Platform Chemicals to Value-Added Products.

The upgrading of biomass-derived compounds has arisen in recent years as a very promising research field in both academia and industry. In this sense, a lot of new processes and products have been developed, often involving levulinic acid as a starting material or intermediate. In the last few years, though, other scaffolds have been receiving growing attention, especially, angelica lactones.
