The Role of Phosphate Group in Doped Cobalt Molybdate: Improved Electrocatalytic Hydrogen Evolution Performance

Abstract: The hydrogen evolution reaction (HER) is a critical process in the electrolysis of water. Recently, much effort has been dedicated to developing low-cost, highly efficient and stable electrocatalysts. Transition metal phosphides are investigated intensively due to their high electronic conductivity and optimized absorption energy of intermediates in acid electrolytes. However, the low stability of metal phosphide materials in air and during electrocatalytic processes causes a decay of performance and hinders the discovery of specific active sites. The HER in alkaline media is more intricate, which requires further delicate design due to the Volmer steps. In this work, we develop phosphorus modified monoclinic β-CoMoO4 as a low-cost, efficient and stable HER electrocatalyst for the electrolysis of water in alkaline media. The optimized catalyst shows a small overpotential of 94 mV to reach a current density of 10 mA cm-2 for the HER with high stability in KOH electrolyte, and an overpotential of 197 mV to reach a current density of 100 mA cm-2. Combined computational and in-situ spectroscopic techniques show P is present as a surface phosphate ion; that electron holes localise on the surface ions and both (P-O1-) and Co3+-OH- are prospective surface active sites for the HER.

Homogenisation, nationalism and war: should we still read Ernest Gellner?*

Abstract: Is homogenising nationalism a consequence of industrialisation? This view has been most forcefully and systematically advanced by Ernest Gellner. The article contests this approach by focusing instead on militarism and militarisation. It therefore identifies the key role of the mass army as presaging the era of mass nationalism and cultural homogenisation. Drawing on a range of authors from history, sociology and political science, the relationship is found to be reciprocal and symbiotic. A preliminary exploration on the possibility of early modern (or pre-modern) forms of cultural homogenisation is preceded by a critical assessment of Gellner's interchangeable use of the terms culture, language and ethnicity.

Principles of electrospraying: A new approach in protection of bioactive compounds in foods.

Abstract: Electrospraying is a potential answer to the demands of nanoparticle fabrication such as scalability, reproducibility, and effective encapsulation in food nanotechnology. Electrospraying (and the related process of electrospinning) both show promise as a novel delivery vehicle for supplementary food compounds since the process can be carried out from an aqueous solution, at room temperature and without coagulation chemistry to produce matrices or particulates in the micro- and nano-range. The presentation of core materials at the nanoscale improves target ability to specific areas of the digestive tract and gives improved control of release rate. Adoption of these electrohydrodynamic atomization technologies will allow the industry to develop a wide range of novel high added value functional foods. To optimize production conditions and maximize throughput, a clear understanding of the mechanism of electrospraying is essential. This article presents a comprehensive review of the principles of electrospraying to produce nanoparticles suitable for food technology application, particularly for use in encapsulation and as nanocarriers.

Brief Report: Don’t Kiss a Sleeping Dog: The First Assessment of “The Blue Dog” Bite Prevention Program

Abstract: Objective The authors attempted to remedy the current lack of empirically evaluated dog-bite prevention programs for children under 7 by assessing children’s learning success with the ‘‘Blue Dog’’ CD. Methods Ninety-six 3-, 4-, 5-, and 6-year-old children used the interactive CD in an initial exposure phase, a training and a testing phase. Half received verbal feedback, and the other half additional practice with parents. All children were re-tested after 2 weeks. Results There were significant increases in safe choices after the training phase at all ages, with older children performing better than younger children. Children still retained their ability to make safe choices after 2 weeks. Interestingly, children practicing with parents performed better than others when under 6 years. Verbal feedback did not play a role, the CD is equally effective without. Conclusions Children learned successfully about safe behavior with dogs; thus, the CD can help educate children about dog-bite prevention.

Some Theoretical Propositions on the Nature of Practice Wisdom

Abstract: • Summary: The author aims to advance the theoretical understanding of practice wisdom by presenting three propositions in relation to its nature and process. A model of practice wisdom is constructed that seeks to address some issues of critical, accountable and knowledgebased practice, while retaining its flexible, creative and intuitive use of practice knowledge. • Findings: It is argued that a critical, accountable and knowledge-based practice wisdom requires distinctive knowledge production processes, the ability to make reasoning explicit, and credible and valuable knowledge. Models of experienced practice development are needed if social work educators are to effectively facilitate the growth of practice wisdom. Such models will need to set out a framework of how such factors as disposition towards knowledge, professional education, practice experience and practice contexts influence whether practitioners engage in wise practice. • Applications: The article makes a contribution to the debate about the nature of social work practice and how entrants to social work can become effective practitioners. Practitioners, researchers and social work educators can use the presented framework to review their thinking about the nature of social work practice and the place practice wisdom has in contemporary social work.
