Synthesis and characterization of catalysts based on mesoporous silica partially hydrophobized for technological applications.

In this work, mesoporous silica mobil composition of matter no. 41 (MCM-41) was synthesized by the sol-gel method. Two different surface modifications were made to transform this material into a very active adsorbent and catalyst support: (i) impregnation of iron nanoparticles and (ii) hydrophobization via chemical vapor deposition (CVD) with ethanol.

The intersection between bioethics and human rights in the light of the universal declaration on bioethics and human rights.

This article aims to explore the increasing interconnection between bioethics and human rights that can be observed in recent international norms relating to biomedicine. To this end, the analysis has been focused on the Universal Declaration on Bioethics and Human Rights (UDBHR) adopted by UNESCO in 2005. Investigating the meanings of the intersection perceived in the UDBHR has led to the understanding of how bioethics and human rights are in accordance, under the normative perspective.
