Grain Size And Orientation

We have investigated the effects of grain size and orientation of copper substrates for the growth of cupric oxide nanowires by thermal oxidation method. Long, less-roughness, high-density, and aligned cupric oxide nanowires have been synthesized by heating (200) oriented copper foils with small grain size in air gas. Long and aligned nanowires of diameter around 80 nm can only be formed within a short temperature range from 400 to 700°C. On the other hand, uniform, smooth-surface, and aligned nanowires were not formed in the case of larger crystallite size of copper foils with (111) and (200) orientation. Smaller grain size of copper foil with (200) orientation is favorable for the growth of highly aligned, smooth surface, and larger-diameter nanowires by thermal oxidation method.

Glucose-, galactose- and lactose-containing photosensitizers based on derivatives of chlorophyll a and bacteriochlorophyll a were synthesized with the use of [3+2] cycloaddition between sugar azides and triple bond derivatives of chlorins and bacteriochlorins. Unlike bacteriochlorin cycloimide, chlorin was detected to form a Cu -complex during the click reaction. An approach to the synthesis of metal-free glycosylated chlorins was developed with the use of "protection" by Zn 2+ cation and subsequent demetalation. It is based on the action of alkynyl chlorin e6 derivative Zn -complex, which is resistant to the substitution by copper cation. Bacteriochlorin p cycloimide conjugate with per-acetylated β-D-lactose was obtained and shown to become water-soluble after unblocking of the lactose hydroxy functions. NMR studies allowed for the elucidation of structure, tautomeric form and conformation of the obtained compounds.

Since the re-establishment of the Scottish Parliament in 1999, successive administrations have reaffirmed their commitment to social justice. However, despite high-level equality policies, social-class inequality is a major feature of Scottish society, affecting all social policy domains, including education. In this article, we provide a brief overview of the development of support for children with learning difficulties and disabilities within the context of Scottish comprehensive schooling. We then consider the way in which ideas of social justice are reflected in education for learners with additional support needs, whose numbers have expanded over recent years and who are particularly likely to live in the most deprived parts of Scotland. Using family case studies, we explore the experiences of families from different social backgrounds, whose children have been identified as having additional support needs. The data suggest that children living in deprived areas experience cumulative disadvantage, attracting stigmatising labels without the benefit of extra resources necessary to improve educational outcomes. By way of contrast, those from more advantaged areas are generally more successful in avoiding stigmatising labels while ensuring that facilitating resources are in place. Findings are discussed within Fraser’s three-dimensional framework of social justice, encompassing distribution, recognition and representation.
