The atom pencil: serial writing in the sub-micrometre domain

The atom pencil we describe here is a versatile tool that writes arbitrary structures by atomic deposition in a serial lithographic process. This device consists of a transversely laser-cooled and collimated cesium atomic beam that passes through a 4-pole atom-flux concentrator and impinges on to micron- and sub-micron-sized apertures. The aperture translates above a fixed substrate and enables the writing of sharp features with sizes down to 280 nm. We have investigated the writing and clogging properties of an atom pencil tip fabricated from silicon oxide pyramids perforated at the tip apex with a sub-micron aperture.

Four nations feminism: Una Troy and Menna Gallie

The emergence of four nations framework in literary and historical scholarship has helped us to arrive at a fuller understanding of the complex and overlapping histories of the islands of Britain and Ireland, while recent research into Wales and Ireland in particular has helped to make the map of our relations more fully comprehensible. But what is the relevance and meaning of the four nations context for womenâ s writing in Ireland and Wales? What part does gender play in the interconnected histories of Wales and Ireland, and how are questions of sexual and artistic identity addressed within texts that imagine British-Irish history in gendered terms? This lecture identifies finds evidence of a feminist reimagining of archipelagic relationships by two writers: Munster novelist and playwright Una Troy, and Welsh writer Menna Gallie, born into a mining community on the western edge of the South Wales coalfields. Both Troy and Gallie wrote novels that deploy plots of female friendship to interrogate the relationship between gender and national affiliation in a four nations context.

Chicana poetics: genre and style in Gloria Anzaldúa and Lorna Dee Cervantes

This thesis conducts a formal study of the poetry of Gloria Anzaldúa and Lorna Dee Cervantes, placing their work in dialogue with genre and style. These two Chicana poets are exemplary of politicised experimentation with poetics, underpinned by a keen awareness of the rich history of form, genre and style. In the work of each poet, two poetic modes are examined: one traditional, and one experimental. Anzaldúa’s uses of the dramatic monologue as a border genre, and her construction of [auto]poetics, stemming from her multi-genre, autobiographical approach to writing, are considered. Cervantes’s complex approach to the construction of docupoetics that achieves a depth of field in terms of merging a multidimensional approach to aesthetics with highly politicised transnational content, as well as her engagement with the longstanding poetic of elegy via various formal points of entry, is investigated. These poetic modes are primarily explored via close readings, supported by a multidisciplinary framework that includes Anzaldúa’s feminist theories of identity and writing, abjection theory, postcolonialism, and transnationalism. Overall, these four key areas demonstrate the ways in which aesthetics is a crucial consideration in the exploration of the broader issues of content and context in Chicana poetry.
