Exhibitionary practices at the intersection of academic research and public display

This text responds to the situation of the field with regard to Artistic Research by drawing attention to the recent shift of discussions towards curating, and more specifically exhibition making, in terms of research practices. The intention is to reflect on the current transformation of contemporary exhibitionary practices and point to an understanding of exhibitionary formats as forms of critical inquiry and knowledge production. I ask how exhibition research might advance more general thinking about research as a way of addressing urgent questions, and what makes exhibition research a distinctive proposition? Thinking about curating in this way would seem not only to have the potential to facilitate non-regulated relations between human subjects but also demonstrates the potential for new epistemological and ontological insights into subject-object relations more broadly

Collision of Art and Ants Worlds - a conversation with Jussi Parikka and Jaroslaw Czarnecki.

Collision of Art and Ant Worlds is a conversation between curator and scholar Joasia Krysa with artists Elvin Flamingo and a scholar Jussi Parikka. The Symbiosity of Creation is a work by Polish artist Elvin Flamingo, that started in 2012 and is intended to continue for at least twenty years until approximately 2034. It was first proposed as doctoral thesis and has since been exhibited at WRO Media Art Biennale 2015, Wrocław, Poland, where the project received a special Critics and Editors of Art Magazines Award. The work was subsequently included in Collective Making (2015-2016), the exhibition series developed by Joasia Krysa during her tenure as Artistic Director of Kunsthal Aarhus, Denmark (until summer 2015) to explore new aesthetic possibilities for making and doing that extended beyond the (anthropo)centrism of the mainstream art world and ideas of artistic autonomy. The Symbiosity of Creation was presented in cooperation with WRO Art Centre. In this conversation, Joasia Krysa (JK), the curator of the exhibition series, talks to Elvin Flamingo (EF) about his collaboration with ants. They are also joined by Jussi Parikka (JP), whose book Insect Media: An Archaeology of Animals and Technology (from 2010) is published in Polish later this year. Insect Media was awarded the 2012 Anne Friedberg prize for Innovative Scholarship, by the Society for Cinema and Media Studies

Exhibitionary practices at the intersection of academic research and public display (second expanded iteration)

This essay explores the relationship between research and curatorial practice, focusing on exhibition-making practices and the understanding of exhibition as not simply the display of objects of research but as the site of research, and consequently as a form of critical inquiry and knowledge production in itself. Taking ERL as a case in point, the essay extends the discussion to consider the specificity of the context within which such practices take place

Improved planar InAs avalanche photodiodes with reduced dark current and increased responsivity

Indium Arsenide (InAs) infrared photodiodes provide high quantum efficiency in the wavelength range of 1.0-3.0 μm. Planar diode configuration has been adopted to reduce surface leakage. In this work, new fabrication procedures for planar InAs avalanche photodiodes (APDs) are reported. Beryllium (Be) ions were implanted into InAs at a relatively low energy of 34 keV. Effects of duration of post implant annealing on the electrical characteristics of InAs APDs were investigated. It was found that a combination of post implant annealing at 500 °C for 15 min and a shallow surface etch produces planar APDs with good characteristics (room temperature dark current density of 0.52 A/cm 2 at -0.2 V and external quantum efficiency of 51% at 1520 nm at -0.3 V). These represent a 3 times reduction in dark current and 1.4 times increase in responsivity, compared to earlier Be-implanted planar InAs APDs. The APDs' avalanche gain characteristics remain similar to those from earlier reports, with a gain of 4 at a relatively low operating bias of 5 V. This suggests the potential of integrating InAs APDs with low voltage readout integrated circuits (ROIC) for development of infrared imaging arrays. The data reported in this paper is available from the ORDA digital repository (DOI: 10.15131/shef.data.6955037)

Overhauser effect in individual InP/GaInP dots

Sizable nuclear spin polarization is pumped in individual InP/GaInP dots in a wide range of external magnetic fields B_ext=0-5T by circularly polarized optical excitation. We observe nuclear polarization of up to ~40% at Bext=1.5T and corresponding to an Overhauser field of ~1.2T. We find a strong feedback of the nuclear spin on the spin pumping efficiency. This feedback, produced by the Overhauser field, leads to nuclear spin bi-stability at low magnetic fields of Bext=0.5-1.5T. We find that the exciton Zeeman energy increases markedly, when the Overhauser field cancels the external field. This counter-intuitive result is shown to arise from the opposite contribution of the electron and hole Zeeman splittings to the total exciton Zeeman energy
