Synthesis of palladium nanoparticles over graphite oxide and carbon nanotubes by reduction in ethylene glycol and their catalytic performance on the chemoselective hydrogenation of para-chloronitrobenzene

Pd nanoparticles have been synthesized over carbon nanotubes (CNT) and graphite oxide (GO) by reduction with ethylene glycol and by conventional impregnation method. The catalysts were tested on the chemoselective hydrogenation of p-chloronitrobenzene and the effect of the synthesis method and surface chemistry on their catalytic performance was evaluated. The catalysts were characterized by N2 adsorption/desorption isotherms at 77 K, TEM, powder X-ray diffraction, thermogravimetry, infrared and X-ray photoelectron spectroscopy and ICP-OES. It was observed that the synthesis of Pd nanoparticles employing ethylene glycol resulted in metallic palladium particles of smaller size compared to those prepared by the impregnation method and similar for both supports. The presence of oxygen groups on the support surface favored the activity and diminished the selectivity. It seems that ethylene glycol reacted with the surface groups of GO, this favoring the selectivity. The activity was higher over the CNT-based catalysts and both catalysts prepared by reduction in ethylene glycol were quite stable upon recycling.

EU Borders and Their Controls: Preventing unwanted movement of people in Europe? CEPS Essay No. 6, 14 November 2013

his Essay attempts to take a step back from the tragic event in the first week of October 2013, when a boat capsized off the Italian island of Lampedusa and some 300 persons drowned seeking safe harbour. It sets out to examine the issue of EU border controls from the perspectives of the technologies, new and old, building on a variety of scholarly disciplines to understand what is happening to border controls on the movement of persons in the EU and why the results are so deadly. The Essay opens with an overview of what actually happens at the EU’s external borders. It then moves on to assess the old and new set of border control technologies that are deployed at the EU external borders, and how new technologies such as those based on automated controls and biometrics, are transforming the classical principles of European border controls. It then covers the reasons why people are refused admission at the EU’s external borders and the extent to which new border and surveillance technologies would assist in the effective controls in light of EU border law. Conclusions are finally offered on the articulation between the facts of EU border controls on persons and the claims and proposals for new technologies that are emerging from the EU institutions.

Benchmarking the Financial Sector in the Southern and Eastern Mediterranean Countries and Projecting 2030 Financial Sector Scenarios. MEDPRO Technical Report No. 31/March 2013

This paper aims at devising scenarios for the development of the financial system in the southern and eastern Mediterranean countries (SEMCs), for the 2030 horizon. The results of our simulations indicate that bank credit to the private sector, meta-efficiency and stock market turnover could reach at best 108%, 78% and 121%, respectively, if the SEMCs adopt the best practices in Europe. These scenarios are much higher than those of the present levels in the region but still lower than the best performers in Europe. More specifically, we find that improving the quality of institutions, increasing per capita GDP, opening further capital account and lowering inflation are needed to enable the financial system in the region to converge with those of Europe.

Institutions and Structural Unemployment: Do Capital-Market Imperfections Matter? CES Germany & Europe Working Papers, No. 00.8, December 2000

This paper analyzes whether differences in institutional structures on capital markets contribute to explaining why some DECO-countries, in particular the Anglo-Saxon countries, have been much more successful over the last two decades in producing employment growth and in reducing unem­ployment than most continental-European DECO-countries. It is argued that the often-blamed labor market rigidities alone, while important, do not provide a satisfactory explanation for these differ­ences across countries and over time. Financial constraints are potentially important obstacles against creating new firms and jobs and thus against coping well with structural change and against moving successfully toward the "new economy". Highly developed venture capital markets should help to alleviate such financial constraints. This view that labor-market institutions should be sup­plemented by capital market imperfections for explaining differences in employment performances is supported by our panel data analysis, in which venture capital turns out to be a significant insti­tutional variable.
