Formation of tough interlocking microstructures in silicon nitride ceramics by dynamic ripening

Abstract: Ceramics based on Si3N4 have been comprehensively studied and are widely used in structural applications1, 2. The development of an interlocking microstructure of elongated grains is vital to ensur ...

Immigration sceptics, xenophobes or racists? Radical right-wing voting in six West European countries

Abstract: Given how central the immigration issue has been for the new radical right-wing parties in Western Europe, many have turned to immigration-related factors in trying to explain their emergence and electoral mobilisation. This research has convincingly shown that immigration scepticism (i.e., wanting to reduce immigration) is among the principal factors for predicting who will vote for a radical right-wing party. However, earlier studies have often uncritically equated immigration scepticism with xenophobia or even racism. By using data from the first round of the European Social Survey (2003) involving six West European countries (Austria,Belgium,Denmark,France,the Netherlands and Norway),this article differentiates between immigration scepticism and xenophobic attitudes. The analy- ses strongly indicate that xenophobic attitudes are a far less significant factor than immigra- tion scepticism for predicting who will vote for the new radical right. Moreover, this article analyses the extent to which anti-immigration frames employed by radical right-wing parties resonate with attitudes held by supporting voters,and to what extent they make a difference for people's decision to vote for the radical right.The analyses indicate that frames linking immigration to criminality and social unrest are particularly effective for mobilising voter support for the radical right. Finally, the article criticises earlier research that explained radical right-wing voting with reference to ethnic competition theory.In contrast to much of the earlier research that used macro-level measures and comparisons, this study uses (self- reported) individual-level data on the degree of ethnic heterogeneity of people's area of residence. Hypotheses derived from ethnic competition theory receive less support than expected, which indicates that earlier research may have overestimated the significance of these factors.

Catalytic amide formation from non-activated carboxylic acids and amines

Abstract: The amide functionality is found in a wide variety of biological and synthetic structures such as proteins, polymers, pesticides and pharmaceuticals. Due to the fact that synthetic amides are still mainly produced by the aid of coupling reagents with poor atom-economy, the direct catalytic formation of amides from carboxylic acids and amines has become a field of emerging importance. A general, efficient and selective catalytic method for this transformation would meet well with the increasing demands for green chemistry procedures. This review covers catalytic and synthetically relevant methods for direct condensation of carboxylic acids and amines. A comprehensive overview of homogeneous and heterogeneous catalytic methods is presented, covering biocatalysts, Lewis acid catalysts based on boron and metals as well an assortment of other types of catalysts.
