The influence of the ligand chelate effect on iron-amine-catalysed Kumada cross-coupling

The performance of Fe-amine pre-catalysts in a representative Kumada reaction is inversely proportional to the lability of the chelate ligand.</p

Diversity, urban space and the right to the provincial city

Using three vignettes of the same physical space this article contributes to understanding of how the right to the city is contested in provincial England in the early twenty-first century. Oral history and ethnographic material gathered in Peterborough between 2010 and 2012 are drawn on to shed new light on the politics of diversity and urban space. This highlights the multiple place attachments and trans-spatial practices of all residents, including the white ethnic majority, as well as contrasting forms of active intervention in space with their different temporalities and affective intensities. The article carries its own diversity politics, seeking to reduce the harm done by racism through challenging the normalisation of the idea of a local, indigenous population, left out by multiculturalism. It simultaneously raises critical questions about capitalist regeneration strategies in terms of their impact both on class inequality and on the environment

Positioning nuclear power in the low-carbon electricity transition

Addressing climate change requires de-carbonizing future energy supplies in the increasingly energy dependent world. The IEA and the IPCC (2014) mention the following as low-carbon energy supply options: ‘renewable energy, nuclear power and fossil fuels with carbon capture and storage’. Positioning nuclear power in the decarbonization transition is a problematic issue and is overridden by ill-conceived axioms. Before probing the axioms, we provide an overview of five major, postwar energy-related legacies and some insight in who is engaged in nuclear activities. We check whether low-carbon nuclear power passes the full sustainability test and whether it is compatible with the unfettered deployment of variable renewable power sourced from the sun and from wind and water currents, delivers two negative answers. We show that the best approach of the sustainable energy transition was Germany’s 2011 decision to phase-out nuclear power for a fast development and full deployment of renewable power. This is the best approach of the sustainable energy transition. We offer five practical suggestions to strengthen and accelerate carbon and nuclear free transitions. They are related to institutional issues like the role of cost-benefit analysis and the mission of the International Atomic Energy Agency, to the costs of nuclear risks and catastrophes, and to the historical record of nuclear technology and business

Rethinking the British World

Copyright @ 2013 The North American Conference on British StudiesThis article rethinks the concept of the “British World” by paying close attention to the voices of those who attended the 1903 Allied Colonial Universities Conference. They identified not one, but three different kinds of British world space. Mapped, respectively, by ideas and emotions, by networks and exchange, and by the specific sites of empire, this article suggests that, in the light of criticisms the British World concept has faced, and in the context of recent scholarship on the social and material production of space, this tripartite approach might offer a useful framework for British and imperial historians interested in the history of the global

Remaking the material fabric of the city: 'Alternative' low carbon spaces of transformation or continuity?

©.This article is about re-making the material fabric of the city and the role that space plays in this. There are many ways of understanding the remaking of the city, including a range of often diverse 'alternative' initiatives which are enacted by neighbourhood, voluntary and civil society groups. We address the construction of 'alternative' urban low carbon spaces and whether these result in transformation of or continuity with dominant ways of thinking about remaking the city. Drawing on examples in Greater Manchester, UK, the article argues that, often despite the intention to promote forms of localist values and strategies as alternatives to dominant accounts of remaking the city, the hand of dominant and particularly state interests is critical in shaping 'alternative' spaces and strategies. This tension - between dominant and alternative - is illustrated through a five-fold typology of the role of space in alternative strategies of remaking the city
