Dehydrocoupling of Ammonia/Amine Boranes and Related Transformations Catalysed by Group 4 Metal Complexes.

Ammonia borane and amine boranes are main group analogues of alkanes, which are characterised by their large gravimetric hydrogen content. This hydrogen can be released in dehydrocoupling and dehydropolymerisation reactions to obtain B-N oligomers and polymers that are of importance as precursors for functional B-N materials. Furthermore, amine boranes are potent reagents for application in transfer hydrogenation reactions, representing a versatile, easy-to-handle alternative to the use of gaseous hydrogen for the reduction of organic compounds.

Development of the public health nursing competency instrument.

This paper describes the development and initial testing of an instrument to measure population-based public health nursing competencies. Although multiple lists of public health competencies exist, literature review did not elicit a valid instrument that could measure changes in public health nursing competency over time. The public health nursing competency instrument, consisting of 195 measurable activities organized in the framework of the nursing process, was developed.
