- Description: The transition period from student nurses to professional nurses has been acknowledged as being very stressful, particularly in the military health service due to the dual transition. The phase is marked as final year nursing students try to consolidate the experience and knowledge gained during their four year training period with clinical decision making and problem solving skills being applied in the work environment. The students require support and guidance to effect a successful transition from being a student to being a professional nurse. The transition of students in the military health setting might be experienced differently due to the context that is vastly different from the other health care settings (Moore, 2006:541). The aim of the research was to explore the experiences of role transition of final year nursing students, particularly their preparedness to take up the role of a professional nurse in the military health setting in order to assist managers and educators to support and facilitate this professional adjustment appropriately. A qualitative, descriptive, contextual design was employed for the study and followed a three-phase approach. Phase one comprised a qualitative approach, where semi-structured and focus group interviews were conducted to gather the data. Nurse managers, nurse educators, final year nursing students and novice professional nurses formed part of the population for the study. Creswell’s method of data analysis was employed in analysing the data. The second phase dealt with the integrative review of literature on the transition of final year nursing students into professional nurses. Data extracted from the guidelines formed themes that were triangulated to form phase three of the study. Lastly, a best practice guideline was developed to facilitate the transition period of final year nursing students to professional nurses. Principles of trustworthiness were adhered to, participants were treated in a fair manner and confidential information was not divulged without the consent of the participants. Participants were asked to take part voluntarily and without coercion. Ethical approval was requested to give consent for the study to be undertaken and ethical principles were adhered to throughout the study. Findings were then disseminated after the conclusion of the study.

- Description: The philosophy of green chemistry has seen much development in the past decade. The use of environmentally benign solvents is amongst the areas of green chemistry that have received the most attention. In this context, imidazolium ionic liquids have been widely reported to offer high product yields, fast reaction rates, excellent selectivity and generally mild working conditions, when used as reaction media. In addition, concerns about costs of solvents and the long-term environmental impact that can potentially result when solvents are discarded after their use have led to focused investigations into solvent-free procedures, as reported in recent literature. We have set out to explore the extent to which these advantages could be realized within our research. Non-volatile, non-flammable imidazolium ionic liquids [bmim][I], [bmim][BF4] and [bmim][PF6] were used as green solvents in ferrocene chemistry. Ferrocenoate esters were synthesised efficiently by the respective DCC/DMAP-promoted reactions of ferrocenecarboxylic acid and substituted benzoic acids or, alternatively, the DMAP-promoted reactions of ferrocenoyl fluoride with a range of substituted phenols in [bmim][BF4] and [bmim][PF6]. High yields and short reaction times were achieved. In addition, the ionic liquid was reused several times without a reduction in product yields. Under solvent-free conditions, DCC/DMAP-promoted reactions provided high yields within 3 min of reaction. The possible rearrangement of one of the intermediates in these reactions was modelled theoretically using density function theory (DFT) at the B3LYP/6-31G* level of approximation. Catalyst-free esterification was achieved by the application of microwave radiation to the reaction of ferrocenoyl fluoride and a range of substituted phenols. All the reactions were complete after 1 min of irradiation and products were isolated in high yield. DPAT, HfCl4, Sc(OTf)3 and Al(OTf)3 were screened as catalysts for esterification in [bmim][BF4] and under solvent-free conditions at various temperatures. All attempts at esterification of ferrocenecarboxylic acid with alcohols and phenols were unsuccessful. The Suzuki cross-coupling reaction was carried out in [bmim][BF4]. The isolated yields are, however, poor and suffer from poor reproducibility with different batches of [bmim][BF4] used.
