Poly(2-vinylpyrazine) as a soluble polymewric ligand and as an electrode coating. Reactions with pantacyanoferrate(II)
No full textThe rate and extent of reaction between H2OFe(CN)53- and poly(2-vinylpyrazine) (PVPz) In homogeneous aqueous solutions have been measured and compared with those for the reaction between the corresponding monomeric species H2OFe(CN)53- and pyrazine). The significant differences observed are attributed to the increasingly negative charge that accumulates on the polymer-metal complex as the reaction proceeds. Solutions of PVPz(Fe(CN)53-)n exhibit almost no electrochemical responses In 0.1 M supporting electrolytes but In 1 M solutions a clear response Is evident. Stable electroactive coatings of PVPz(Fe(CN)93-)n on electrode surfaces can be prepared by exposing cross-linked deposits of PVPz to aqueous solutions of H2OFe(CN)53-. The apparent formal potentials of the redox groups in such coatings vary with the concentration of the supporting electrolyte in the way expected for cation permselective membranes. With homogeneous solutions of PVPz about 30 % of the pyrazfne groups could be coordinated to -Fe(CN)53- anions but the maximum extent of binding of -Fe(CN)53- to cross-linked coatings of PVPz was only about half as large. © 1989, American Chemical Society.

Anson O. Kittredge: Early accounting pioneer
No full textLeafing through early accounting journals from the last two decades of the 19th century, accounting historians and enthusiasts piece together the history of accountancy in the U.S., yet pay little attention to the editors of these journals who at times almost single-handedly willed their existence, clearing the road for modern accounting journals. Anson O. Kittredge, who was probably the most outstanding and influential editor of the 19th century, was also an author, teacher, CPA examiner, innovator, practitioner, and organizer

Cyan-Emitting Cu(I) Complexes and Their Luminescent Metallopolymers
No full textCopper complexes have shown great versatility and a wide application range across the natural and life sciences, with a particular promise as organic light-emitting diodes. In this work, four novel heteroleptic Cu(I) complexes were designed in order to allow their integration in advanced materials such as metallopolymers. We herein present the synthesis and the electrochemical and photophysical characterisation of these Cu(I) complexes, in combination with ab initio calculations. The complexes present a bright cyan emission (λem ~ 505 nm) in their solid state, both as powder and as blends in a polymer matrix. The successful synthesis of metallopolymers embedding two of the novel complexes is shown. These copolymers were also found to be luminescent and their photophysical properties were compared to those of their polymer blends. The chemical nature of the polymer backbone contributes significantly to the photoluminescence quantum yield, paving a route for the strategic design of novel luminescent Cu(I)-based polymeric materials
Energy Efficiency Improvements in Dry Drilling with Optimised Diamond-Like Carbon Coating
No full textWe demonstrate enhancements of performance and energy efficiency of cutting tools by deposition of diamond-like carbon (DLC) coatings on machine parts. DLC was deposited on steel drill bits, using plasma enhanced chemical vapour deposition (PECVD) with the acetylene precursor diluted with argon, to produce a surface with low friction and low wear rate. Drill bit performance in dry drilling of aluminium was quantified by analysis of power consumption and swarf flow. Optimised deposition conditions produced drill bits with greatly enhanced performance over uncoated drill bits, showing a 25% reduction in swarf clogging, a 36% reduction in power consumption and a greater than five-fold increase in lifetime. Surface analysis with scanning electron microscopy shows that DLC coated drills exhibit much lower aluminium build up on the trailing shank of the drill, enhancing the anti-adhering properties of the drill and reducing heat generation during operation, resulting in the observed improvements in efficiency. Variation of drilling efficiency with argon dilution of precursor is related to changes in the microstructure of the DLC coating

The assessment of complex tasks: a double reading
No full textThis is an Accepted Manuscript of an article published by Taylor & Francis in Studies in Higher Education on 15 August 2006, available online: http://www.tandfonline.com/10.1080/03075070500339988.Drawing on Bourdieu's theory of social practice, the author challenges common-sense notions of objectivity and subjectivity which inform assessment practice, and argues for assessment as a socially situated interpretive act. A case study of an engineering community of practice at a South African university illustrates the multiple subjectivities that shape assessors' interpretations of student performance. This case study contributes to an understanding of academic professional judgment as a ‘double reading' - an iterative movement between different modes of knowledge which comprise the objective and the subjective. The author concludes with a brief discussion of the theoretical and practical implications of this for how academic communities of practice come to judge and how these judgments are validated
