Literary linguistics: Open Access research in English language

Strathprints makes available Open Access scholarly outputs by English Studies at Strathclyde. Particular research specialisms include literary linguistics, the study of literary texts using techniques drawn from linguistics and cognitive science.

The team also demonstrates research expertise in Renaissance studies, researching Renaissance literature, the history of ideas and language and cultural history. English hosts the Centre for Literature, Culture & Place which explores literature and its relationships with geography, space, landscape, travel, architecture, and the environment.

Abstract

We report on the fabrication of high-optical-quality microlens arrays based on ultraviolet (UV)-curable polymer adhesive. The lenses are suitable, amongst other applications, for high-transmission and projection of the output of UV micropixellated light-emitting diodes. The microlenses were fabricated using a resist-reflow technique with reactive ion etching. An O/sub 2/--CF/sub 4/ etch-gas chemistry, where atomic fluorine eliminates the carbon-related polymer residue at the etch front effectively, resulted in etch rates of 1.4 /spl mu/m per minute for the polymer. Spherical microlenses of root mean square surface roughness 3 nm were obtained.
