- Abstract in Undetermined In media, policymaking and research, increasing attention is drawn to the phenomenon of ‘green political consumerism’, referring to consumerrelated practices that are based on concerns beyond the traditional criteria of product quality and price. Political consumerism is about expressing non-economic values, that is, values beyond the direct, economic self-interest of consumers. Such values may concern social conditions of farmers producing our food or the welfare of animals used in food production. Green political consumerism is a concept that highlights a concern for environmental conditions, although these concerns often overlap with social and animal-related ones (Boström & Klintman 2008). Micheletti (2003) has defi ned political consumerism as consumers’ ‘individualistic collective action’, practiced, for instance, through boycotting or buycotting certain products and services. For the purpose of this chapter, it is important to mention that there is a need to keep the defi nition of political consumerism subject to continuous discussion and debate. A main claim in this chapter is that it is particularly important not to equal green political consumption merely with purchases of eco-labeled products and services. To follow such principles of consumption or to have small ecological footprints due to smaller economic resources, for example, are two very diff erent things, which should both be of interest in debates about political consumerism.

Carbon, glass and basalt fiber reinforced polybenzoxazine : The effects of fiber reinforcement on mechanical, fire, smoke and toxicity properties
- 2020

Journal article (peer-reviewed)abstract
- Bisphenol F and aniline-based benzoxazine monomers were selected to fabricate basalt, glass and carbon fiber reinforced polybenzoxazine via vacuum infusion, respectively. The impacts of the type of fiber reinforcement on the resulting material properties of the fiber reinforced polymers (FRPs) were studied. FRPs exhibited a homogenous morphology with completely impregnated fibers and near-zero porosity. Carbon fiber reinforced polybenzoxazine showed the highest specific mechanical properties because of its low density and high modulus and strength. However, regarding the flammability, fire, smoke and toxicity properties, glass and basalt reinforced polybenzoxazine outperformed carbon fiber reinforced polybenzoxazine. This work offers a deeper understanding of how different types of fiber reinforcement affect polybenzoxazinebased FRPs and provides access to FRPs with inherently good fire, smoke and toxicity performance without the need for further flame retardant additives. © 2020 by the authors.

Investigation of copper alloying in a TNTZ-Cux alloy
- 2019

Journal article (peer-reviewed)abstract
- Alloying copper into pure titanium has recently allowed the development of antibacterial alloys. The alloying of biocompatible elements (Nb, Ta and Zr) into pure titanium has also achieved higher strengths for a new alloy of Ti-1.6 wt.% Nb-10 wt.% Ta-1.7 wt.% Zr (TNTZ), where strength was closer to Ti-6Al-4V and higher than grade 4 titanium. In the present study, as a first step towards development of a novel antibacterial material with higher strength, the existing TNTZ was alloyed with copper to investigate the resultant microstructural changes and properties. The initial design and modelling of the alloy system was performed using the calculation of phase diagrams (CALPHAD) methods, to predict the phase transformations in the alloy. Following predictions, the alloys were produced using arc melting with appropriate heat treatments. The alloys were characterized using energy dispersive X-ray spectroscopy in scanning transmission electron microscopy (STEM-EDS) with transmission Kikuchi diffraction (TKD). The manufactured alloys had a three-phased crystal structure that was found in the alloys with 3 wt.% Cu and higher, in line with the modelled alloy predictions. The phases included the α-Ti (HCP-Ti) with some Ta present in the crystal, Ti2Cu, and a bright phase with Ti, Cu and Ta in the crystal. The Ti2Cu crystals tended to precipitate in the grain boundaries of the α-Ti phase and bright phase. The hardness of the alloys increased with increased Cu addition, as did the presence of the Ti2Cu phase. Further studies to optimize the alloy could result in a suitable material for dental implants.
