Magnetoferritin: in vitro synthesis of a novel magnetic protein

Abstract: The iron storage protein ferritin consists of a spherical polypeptide shell (apoferritin) surrounding a 6-nanometer inorganic core of the hydrated iron oxide ferrihydrite (5Fe2O3.9H2O). Previous studies have shown that the in vitro reconstitution of apoferritin yields mineral cores essentially identical to those of the native proteins. A magnetic mineral was synthesized within the nanodimensional cavity of horse spleen ferritin by the use of controlled reconstitution conditions. Transmission electron microscopy and electron diffraction analysis indicate that the entrapped mineral particles are discrete 6-nanometer spherical single crystals of the ferrimagnetic iron oxide magnetite (Fe3O4). The resulting magnetic protein, "magnetoferritin," could have uses in biomedical imaging, cell labeling, and separation procedures.

Large mode area photonic crystal fibre

Abstract: The authors report the realisation of a new design for a large mode area monomode optical fibre. This photonic crystal fibre will guide only a single mode, no matter how large the fibre diameter, provided the shape is kept constant. This is demonstrated with a fibre which has a core diameter equal to approximately 50 free-space wavelengths.

Identities and Identity Work in Organizations

Abstract: Identities, people's subjectively construed understandings of who they were, are and desire to become, are implicated in, and thus key to understanding and explaining, almost everything that happens in and around organizations The research contribution that this review paper makes is threefold First, it analyses the often employed but rarely systematically explored concept ‘identity work’, and argues that it is one metaphor among many that may be useful in the analysis of professional and more generally work identities Second, it focuses on five fundamental, interconnected debates in contemporary identities research centred on notions of choice, stability, coherence, positivity and authenticity Third, it outlines the roles that the concept ‘identity work’ may play in bridging levels of analysis and disciplinary boundaries, and sketches some possible future identities-focused ideas for further research Under-specification has meant that ‘identity’ has not always fulfilled its analytical promise in either theoretical explorations of identities issues or in empirical studies of identities in practice; and it is to these ends that this paper seeks to contribute
