[ES] En la presente tesis doctoral el principal objetivo ha sido desarrollar una nueva metodología para producir monoésteres, diésteres y polioles derivados de ácidos grasos de forma continua. Una producción en continuo ...
[EN] We show a facile method to prepare surface-clean monodispersed small and stable CuOx nanoparticles with controllable average sizes from below 1 nm up to similar to 5 nm without using bulk capping agent. Structural and ...
[EN] Group 15 elements in zero oxidation state (P, As, Sb and Bi), also called pnictogens, are rarely used in catalysis due to the difficulties associated in preparing well-structured and stable materials. Here, we report ...
[EN] The substitution of catalytic metals by p-block main elements has a tremendous impact not only in the fundamentals but also in the economic and ecological fingerprint of organic reactions. Here we show that few-layer ...

[EN] alpha,alpha',N-Tnarylbisenamines have been efficiently formed and isolated for the first time The synthesis is based on an unprecedented gold(I)-catalyzed double intermolecular hydroamination between N-arylamines and ...
We have seen the work on gold catalysis to increase exponentially
in the last few years. This is specifically true for homogeneous
gold(I) and some gold(III) catalysts. Despite further
expansion of gold catalysts to ...
[EN] The preparation of novel efficient catalyststhat could be applicable in industrially important chemical processeshas attracted great interest. Small subnanometer metal clusters can exhibit outstanding catalytic ...
[EN] The exact chemical structure of non-crystallising natural products is still one of the main challenges in Natural Sciences. Despite tremendous advances in total synthesis, the absolute structural determination of a ...
