Abstract: Composite materials are used in a wide range of applications such as automotive, aerospace and renewable energy industries. But they have not been properly recycled, due to their inherent nature of heterogeneity, in particular for the thermoset-based polymer composites. The current and future waste management and environmental legislations require all engineering materials to be properly recovered and recycled, from end-of-life (EOL) products such as automobiles, wind turbines and aircrafts. Recycling will ultimately lead to resource and energy saving. Various technologies, mostly focusing on reinforcement fibres and yet to be commercialized, have been developed: mechanical recycling, thermal recycling, and chemical recycling. However, lack of adequate markets, high recycling cost, and lower quality of the recyclates are the major commercialization barriers. To promote composites recycling, extensive R&D efforts are still needed on development of ground-breaking better recyclable composites and much more efficient separation technologies. It is believed that through the joint efforts from design, manufacturing, and end-of-life management, new separation and recycling technologies for the composite materials recycling will be available and more easily recyclable composite materials will be developed in the future.

TL;DR: In this article, the work function, referred as electrode potential vs SHE, of modified (oxyhydr)oxide surfaces of AA1050 was studied upon exposure to different relative humidity (40% and 90%) and aging (40 and 240 min) by utilizing scanning Kelvin probe (SKP).

TL;DR: In this article, the influence of seawater environment in combination with a welded state is described and the fracture and crack initiation mechanisms are explained, showing that the penetration of seafloor seawater into sub-surface pores, that are present in the welded material, results in a significant drop in fatigue life time.

TL;DR: In this article, the state of the art of the most important fuel cell technologies and new design concepts, integrated use of novel materials and how fuel cells can be integrated in the chemical industry and in larger energy providing systems using renewables.

TL;DR: In this article, the scanning Kelvin probe potential distributions in the Evans drop were measured and it was found that within the droplet no separate anode and cathode can be distinguished in the potential profile.
