Adding critical sensibilities to domestic communication technologies
This paper presents suggestions for a more pragmatic approach to the design of emerging and future domestic communication technologies, particularly technologies destined for the home that maybe deemed 'ubiquitous'. This is achieved through two critical reviews of a small number of social studies related to the design and use of existing and emerging communication technologies. The first review...
متن کاملDivergent light-harvesting complexes
‡Current address: University of Washington, School of Oceanography, Box 357940, Seattle, WA 98195-7940, USA. †Co first authors. Approximately one-half of the total primary production on Earth occurs in the oceans [1]. Although hundreds of species contribute to oceanic productivity, members of two cyanobacterial genera – Prochlorococcus [2,3] and Synechococcus [4] – are responsible for a signifi...
متن کاملLight-Harvesting Complex: Rings of light
The atomic structure of the bacterial light-harvesting complex helps to explain how the energy of sunlight is efficiently absorbed and transferred between bacteriochlorophyll molecules towards the reaction centre.

متن کاملLight Harvesting for Organic Photovoltaics
The field of organic photovoltaics has developed rapidly over the last 2 decades, and small solar cells with power conversion efficiencies of 13% have been demonstrated. Light absorbed in the organic layers forms tightly bound excitons that are split into free electrons and holes using heterojunctions of electron donor and acceptor materials, which are then extracted at electrodes to give usefu...
