Mesostructured zeolites: bridging the gap between zeolites and MCM-41

Surfactant-templating is one of the most versatile and useful techniques to implement mesoporous systems into solid materials. Various strategies based on various interactions between surfactants and solid precursors have been explored to produce new structures. Zeolites are invaluable as size- and shape-selective solid acid catalysts. Nevertheless, their micropores impose limitations on the mass transport of bulky feed and/or product molecules. Many studies have attempted to address this by utilizing surfactant-assisting technology to alleviate the diffusion constraints. However, most efforts have failed due to micro/mesopore phase separation. Recently, a new technique combining the uses of cationic surfactants and mild basic solutions was introduced to synthesise mesostructured zeolites. These materials sustain the unique characteristics of zeolites (i.e., strong acidity, crystallinity, microporosity, and hydrothermal stability), including tunable mesopore sizes and degrees of mesoporosity. The mesostructured zeolites are now commercially available through Rive Technology, and show superior performance in VGO cracking. This feature article provides an overview of recent explorations in the introduction of mesoporosity into zeolites using surfactant-templating techniques. Various porous materials, preparation methods, physical and catalytic properties of mesostructured zeolites will be discussed.

MOOCs, Open educational resources and social networking: bridging the gap between informal and formal learning

MOOCs and open educational resources (OER) provide a wealth of learning opportunities for people around the globe, many of whom have no access to formal higher education. OER are often difficult to locate and are accessed on their own without support from or dialogue with subject experts and peers. This paper looks at whether it is possible to develop effective learning communities around OER and whether these communities can emerge spontaneously and in a self-organised way without moderation. It examines the complex interplay between formal and informal learning, and examines whether MOOCs are the answer to providing effective interaction and dialogue for those wishing to study at university level for free on the Internet.

The Governance Gap in European Security and Defence. CEPS Policy Brief No. 310, 19 December 2013

The true causes of the EU’s inertia as a security actor in its neighbourhood and beyond are not a lack of capability or even austerity measures, but the absence of a core group of states committed to driving integration forward, argues Giovanni Faleg. Member states are reluctant to set clear common strategic priorities and struggle to agree on a revision of the institutional rules. Their strategic cultures and interests differ significantly; they hold different visions of the Common Security and Defence Policy (CSDP) and are unwilling to use the CSDP instruments at their disposal.

Supporting Access to Finance by SMEs: Mapping the initiatives in five EU countries. ECMI Research Report No. 9, April 2014

This paper maps the initiatives to support access to finance for small- and medium-sized enterprises (SMEs) that were available at national level in 2012 in the five biggest European economies (Germany, France, the UK, Italy and Spain). This mapping distinguishes initiatives promoted and financed primarily through public resources from those developed independently by the market. A second breakdown is proposed for those sources of finance with different targets, i.e. whether the target is debt financing (typically bank loans at favourable conditions, public guarantees on loans, etc.) or equity financing (typically venture capital funds, tax incentives on equity investments, etc.). A broad set of initiatives has been implemented to close the funding gap of SMEs in these five countries. The total amount of public spending for SMEs, however, has remained well below 1% of GDP. Public subsidisation of bank loans has been by far the most diffused type of intervention. Despite the fact that this strategy might prove to be effective in the short term, it fails to address long-term sustainability issues via a more diversified set of financing tools.

The transatlantic growth gap. CEPS Commentary, 5 August 2014

Daniel Gros argues in this commentary that the cause of the transatlantic growth gap following the recovery starting in 2010 from the global financial crisis should not be sought in excessive eurozone austerity or the excessive prudence of the European Central Bank. Rather, compared to the US, he argues that the excess debt created in the EU during the boom years has been much more difficult to work off. He acknowledges that European officials are right to promote structural reforms of EU countries’ labour and product markets, but advises that they should also focus on overhauling and accelerating bankruptcy procedures, so that losses can be recognised more quickly and over-indebted households can start afresh, rather than being shackled for years.

Closing the gap? Military co-operation from the Baltic Sea to the Black Sea. OSW Report, December 2012

The contracting defence budgets in Europe, the difficulties in developing the EU’s security policy, NATO's transformation, the reorientation of US security policy and the problems experienced by European defence industries – all together have in recent years created an increased interest in political, military and military-technological co-operation in Europe.It has manifested itself in concepts of closer co-operation within NATO and the EU (smart defence and pooling&sharing), bilateral and multilateral initiatives outside the structures of NATO and the EU (such as the Nordic Defence Co-operation or the Franco-British co-operation) and debates about the prerequisites, principles and objectives of bilateral, multilateral and regional security and defence co-operation. The present report aims to analyse the potential for security and defence co-operation among selected countries in the area between the Baltic Sea and the Black Sea, i.e. the Nordic states (Denmark, Finland, Norway and Sweden), the Baltic states (Lithuania Latvia and Estonia), Poland's partners in the Visegrad Group (the Czech Republic, Hungary and Slovakia) as well as Romania and Bulgaria. The authors were guided by the assumption that those states are Poland's natural partners for closer regional military co-operation. It may complement ‘the Western’ direction of Poland's security and defence policy, i.e. relations with the partners from the Weimar Triangle and the US. Its goal is not to replace the existing security structures but rather to strengthen military capabilities in the region within NATO and the EU.

The 2005 Reform of the Stability and Growth Pact: Too Little, Too Late? Bruges European Economic Research (BEER) Papers 6/November 2006

This paper analyses the main critiques addressed by the literature and the policymakers to the 1997 Stability and Growth Pact. It further indicates to what extent the 2005 reform of the Pact meets those critics. It finally argues that the 2005 reform may be too little and arrive too late to restore the Pact credibility, ensure its enforceability and correctly set the derogations to the excessive deficit procedure on the nature of the shocks which cause the output gap rather than its size: a 3% of GDP limit on deficit spending may be a too binding constraint in front of a strongly negative demand shock, while it is irrationally large in front of a supply shock. Some empirical evidence is provided to identify in the last years strongly negative demand shocks from other shocks in the 25 EU Member States. Had this identifying method been adopted in November 2003, the European Commission and the Council would have both agreed to stop the excessive deficit procedure against Germany, but they would have both proceeded against France which apparently was not at the time hit by a strongly negative demand shock.

The grand divergence: global and European current account surpluses. Bruegel Working Paper 2015/08, 13 August 2015

Global current account imbalances widened before the 2007/2008 crisis and have narrowed since. While the post-crisis adjustment of European current account deficits was in line with global developments (though more forceful), European current account surpluses defied global trends and increased. We use panel econometric models to analyse the determinants of medium-term current account balances. Our results confirm that higher fiscal balances, higher GDP per capita, more rapidly aging populations, larger net foreign assets, larger oil rents and better legal systems increase the medium-term current account balance, while a larger growth differential and a higher old-age dependency ratio reduce it. European current account surpluses became excessive during the past twelve years according to our estimates, while they were in line with model predictions in the preceding three decades. Generally, the gap between the actual current account and its fitted value in the model has a strong predictive power for future current account changes. Excess deficits adjust more forcefully than excess surpluses. However, in the 2004-07 period, excess imbalances were amplified, which was followed by a forceful correction in 2008-15, with the exception of European surpluses.
