PurposeThe purpose of this paper is to examine blockchain's roles in promoting ethical sourcing in the mineral and metal industry.Design/methodology/approachIt analyzes multiple case studies of blockchain projects in the mineral and metal industry.FindingsIt gives detailed descriptions of how blockchain-based supply chain networks' higher density of information flow and high degree of authenticity of information can increase supply chain participants' compliance with sustainability standards. It gives special consideration to blockchain systems' roles in overcoming the deficits in the second party and the third-party trust. It also demonstrates how blockchain-based supply chain networks include outside actors and configure the supply chain networks in a way that enhances the empowerment of marginalized groups.Practical implicationsIt suggests various mechanisms by which blockchain-based supply chain networks can give a voice to marginalized groups.Originality/valueIt demonstrates how blockchain is likely to force mineral and metal supply chains to become more traceable and transparent.

Abstract This article is concerned with the potential for private action to improve sourcing practices to promote biodiversity. More specifically this article examines the Union for Ethical BioTrade (UEBT) and its verification and certification of ‘sourcing with respect’: that is, sourcing ingredients from biodiversity in a way that is respectful to both the local environment and people. While key international biodiversity treaties and instruments—such as the Convention on Biological Diversity (CBD) and Nagoya Protocol—encourage public actors to work with private actors to develop methods for the sustainable use of biological resources, our examination of UEBT shows that there are concerns over the standards, implementation and enforcement of private initiatives. In conclusion, we suggest two key ways in which transnational or public/private initiatives can be strengthened. First, via more proactively promoting public/private cooperation, including about how certification is used to reduce inconsistency and consumer overload or confusion. Secondly, by placing greater emphasis on mechanisms that place pressure on supply chain actors to source in ways that promote biodiversity.

It has been found that the abrasion of diamond-on-diamond depends on the crystal orientation. For a {100} face, the friction coefficient for sliding along <011> is much higher than that along <001>. For a {111} face, the abrasion along <11> is different from that in the reverse direction <>. To interpret these effects, a microcleavage mechanism was proposed in which the {100} and {111} surfaces were assumed to be composed of square-based pyramids and trigonal protrusions, respectively. Reflection electron microscopy (REM) has been applied to image the microstructures of these diamond surfaces.{111} surfaces of synthetic diamond:The synthetic diamonds used in this study were obtained from the De Beers Company. They are in the as-grown condition with grain sizes of 0.5-1 mm without chemical treatment or mechanical polishing. By selecting a strong reflected beam in the reflection high-energy electron diffraction (RHEED) pattern, the dark-field REM image of the surface is formed (Fig. 1).

Durant la période de confinement, la chaîne d’approvisionnement de la filière nucléaire a pleinement joué son rôle. Mais en sort-elle renforcée ? Si l’expérience acquise par les différents acteurs de la supply chain va lui offrir plus de robustesse, les difficultés économiques rencontrées par les autres filières industrielles, comme l’automobile ou l’aéronautique, risquent de fragiliser des acteurs essentiels à la filière nucléaire.
