Photocatalytic degradation of methyl orange using biologically enhanced tin oxide nanoparticles under UV-irradiation

Tin oxide nanoparticles (size?=?14 nm) have been prepared using DNA, a biological molecule, by co-precipitation method. The SnO₂ catalysts were characterized by X-ray diffraction, scanning electron microscope, transmission electron spectroscopy, fourier transform infra-red spectroscopy, photoluminescence spectroscopy and UV–Vis spectroscopy. The photocatalytic properties of SnO₂ nanoparticles were investigated via methyl orange as a model organic compound under UV light irradiation. The study proves SnO₂ as an efficient catalyst in removing organic pollutants in water.     

Why do they return? Beyond the economic drivers of graduate return migration

This paper explores the factors that shape the location choices of formerly mobile graduates (FMGs) initially resident in Sardinia, Italy, a less developed European region. Combining qualitative and quantitative techniques, the paper examines the reasons why some individuals decide to return after their studies, the factors that shape their decisions and how these choices unfolded in space and time. It counters the literature, which suggests that migration is a one-off linear process driven only by wealth-maximising behaviour, positing rather that access to opportunities in open meritocratic job markets and circular migration trajectories are far more salient to FMGs. This suggests that policy makers should concentrate on promoting labour market opportunities and invest in social networks that will aid brain circulation.     

Secondary metabolism in Penicillium expansum: Emphasis on recent advances in patulin research

The plant pathogenic fungus Penicillium expansum is a major concern of the global food industry due to its wide occurrence and ability to produce various mycotoxins, of which the most significant is patulin. Relatively less highlighted in the literature, in comparison with the other food-borne mycotoxins, patulin is one of the main factors in economic losses of vegetables and fruits. Otherwise, patulin is a health hazard which results in both short-term and long-term risks. This review includes knowledge on the biosynthetic mechanisms used for secondary metabolite production in P. expansum, with special emphasis on patulin biosynthesis. The abiotic factors triggering the production of patulin and the strategies developed to reduce or prevent the contamination by this mycotoxin are comprehensively discussed. The database presented in this review would be useful for the prioritization and development of future research.
