Amorphous calcium carbonate (ACC) occurs with varying stabilities in different organisms. It is thought that the stability is influenced by certain ions and proteins. We describe here a study investigating the particular influence of phosphate ions on the stability of ACC. Synthesised ACC was treated with different concentrations of Na2HPO4 and molar ratios of PO4:Ca ≥ 12:1 were shown to be effective in preventing crystallisation of ACC to calcite. The nature of the resulting sample is discussed.

This paper considers the Royal Historical Society (RHS)'s ‘Race, Ethnicity & Equality in UK History’ report published in 2018. The report contained the findings of a survey sent to staff and students working or studying in History higher education in the United Kingdom. In this paper, I reflect on the various findings of the report related to staff and student numbers, the attainment gap between white and Black and Ethnic Minority students, the curriculum, and racial harassment in History within universities. The RHS report emerged out of the work done by a number of organisations championing race and equality in the sector over decades. By connecting the work of RHS to these earlier initiatives it is possible to map a broader societal change in the historical sector to address historic inequalities, racialised disadvantage and structural exclusion. The RHS and institutions such as Runnymede Trust, the Institute of Historical Research, and Leading Routes are championing greater racial and ethnic equality which reflects broader political, economic and cultural transformations taking place in Britain. In this paper, I show how the RHS is part of an important conversation in foregrounding racial and ethnic equality in the historical profession to the inevitable benefit of History higher education.

The nature of Ireland's place within the British Empire continues to attract significant public and scholarly attention. While historians of Ireland have long accepted the complexity of Ireland's imperial past as both colonised and coloniser, the broader public debate has grown more heated in recent months, buffeted by Brexit, the Decade of Centenaries and global events. At the same time, the imperatives of social movements such as Black Lives Matter and Decolonising the Curriculum have asked us to reflect on the assumptions, hierarchies and norms underpinning the structures of society, including the production of knowledge and the higher education system. This round table brings together scholars from diverse disciplinary and methodological backgrounds to examine the prospects, possibilities and challenges of what decolonising Irish history might mean for our field. It sets these discussions within broader frameworks, considering both the relationship of Irish historical writing to postcolonial theory and the developments in the latter field in the last twenty years. It also reflects on the sociology of our discipline and makes suggestions for future research agendas.
