The composition of the reducing gas in the activation of Co Fischer-Tropsch synthesis catalysts determines the nature of the catalytically active Co species. This study reports on the effect of H2versus syngas (H2/CO = 2) on the reducibility of Co3O4nanoparticles supported on hollow carbon spheres, using ex situ and in situ high-resolution aberration-corrected analytical electron microscopy. High-

When selecting a solvent for a given solute, the strongly held idiom “like dissolves like”, meaning that polar solvents are used for polar solutes, is often used. This idea has resulted from the concept that most molecular solvents are homogeneous. In a deep eutectic solvent (DES), however, both components can be ionic or non-ionic, polar or non-polar. By tuning the components, DESs can solubilize

Mass production and consumption based on virgin materials have been the mainstream practice for decades across industrialised nations. Resource consumption has reached an unsustainable level, leading to devastating environmental impacts. For a more sustainable future, not only environmentally but economically and socially, material cycles need to be slowed down and, if possible, closed. Upcycling

Non-technical summary Mainstreaming climate objectives into sectoral work and policies is widely advocated as the way forward for sustainable public-private action. However, current knowledge on effective climate mainstreaming has rarely translated into policy outcomes and radical, transformational change. This 'implementation gap' relates to the limitations of current approaches, which do not ade

Forests provide grounds for human well-being through direct material, indirect environmental, and immaterial contributions. Here, we analyze the example of Hispaniola to understand reasons for (un)sustainable forest use. We pursue a dynamic comparative case study of the island's two countries from a political ecology perspective. From the literature, we derive a set of socio-economic hypotheses fo

This paper describes the changing nature of the English and Swedish states between 1800 and 2020 from the perspective of ordinary citizens. We identify 13 typical life situations and then describe the types of citizens who interacted with the state, the number and types of public officials with whom they interacted, and where those interactions took place. We distinguish among three typical social

Efficient manipulation of antiferromagnetic (AF) domains and domain walls has opened up new avenues of research towards ultrafast, high-density spintronic devices. AF domain structures are known to be sensitive to magnetoelastic effects, but the microscopic interplay of crystalline defects, strain and magnetic ordering remains largely unknown. Here, we reveal, using photoemission electron microsco

OBJECTIVE: The aim of the current study is to understand why some individuals avoid developing Parkinson disease (PD) despite being at relatively high genetic risk, using the largest datasets of individual-level genetic data available.METHODS: We calculated polygenic risk score to identify controls and matched PD cases with the highest burden of genetic risk for PD in the discovery cohort (Interna
