The surface geometry of carbon monoxide and oxygen co-adsorbed on Ni{111}

Low energy electron diffraction (LEED) structure determinations have been performed for the p(2 x 2) structures of pure oxygen and oxygen co-adsorbed with CO on Ni{111}. Optimisation of the non-geometric parameters led to very good agreement between experimental and theoretical IV-curves and hence to a high accuracy in the structural parameters. In agreement with earlier work atomic oxygen is found to adsorb on fee sites in both structures. In the co-adsorbed phase CO occupies atop sites. The positions of the substrate atoms are almost identical, within 0.02 Angstrom, in both structures, implying that the interaction with oxygen dominates the arrangement of Ni atoms at the surface.

Prêt-à-Médiatiser by House of POLLYFIBRE

Prêt-à-Médiatiser by House of POLLYFIBRE is a performance/film that takes the fashion show catwalk as a site for exploration, with a focus on the dialogue between liveness and mediatisation. The performance showcases a clothing collection that has been designed to be documented and thus is challenged in the context of the live event. Motivated by the 2-dimensionality and biased perspective of mediated images such as magazine photography, social network profiles images and the surfaces of digital interfaces, the garments are one sided and obstruct the models in their attempt to play out familiar fashion poses, unless they align themselves 'correctly' for the lense. There is material metaphor and wordplay throughout, for example the clothing pieces are made from interfacing fabrics that are physically cut, pasted and layered to create the rigid flat silhouettes. The performance is accompanied by live sound created by tools of the fashion industry (including scissors and camera clicks) that have been adapted and amplified to be used as instruments. The audience and press are invited to document the live event and the subsequent film is made using footage collated from the crew, the audience and the official press

Effect of "Pollutants" on the functionality of breathable roofing membranes in a bat roost

The performance of breathable roofing membranes (BRM’s) in buildings where bats roost have been investigated using experimental measurements and numerical simulations. Measurement techniques as outlined in BS EN ISO 12572 of membranes from manufacturers in its pure state and those that have been contaminated with bat urine, faeces and natural oils transmitted via fur because they were found in bat roost have been tested for their permeability functions. The findings from this shows that there are significant differences between the functionality of the pure samples compared to the contaminated samples, with an average of about 20-30% reduction in functionality. This paper integrates modelling techniques using a heat, air and mass software with a simulink interface on a Matlab platform to investigate the moisture transfer properties of the BRMs. The simulation results demonstrate high level of condensation formation when the BRM is contaminated as compared to when it is not.
