Thiolate protected metal clusters are valuable precursors for the design of tailored nanosized catalysts. Their performance can be tuned precisely at atomic level, e. g. by the configuration/type of ligands or by partial/complete removal of the ligand shell through controlled pre-treatment steps. [...]

12 p, 2.1 MB Alexander the Great, the royal throne and the funerary thrones of Macedonia / Palagia, Olga (National and Kapodistrian University of Athens)
There is no evidence in either Greece or Macedon in the archaic and classical periods that the throne functioned as a symbol of royalty. Thrones were for the gods and their priests. Only the king of Persia used a royal throne and even had portable thrones for his campaigns. [...]
No hay evidencias ni en Grecia ni en Macedonia durante los períodos arcáico y clásico de que los tronos funcionasen como símbolos de realeza. Los tronos eran para los dioses y sus sacerdotes. Sólo el Rey de Persia empleaba un trono real e incluso poseía tronos portables para sus campañas. [...]

32 p, 913.8 KB Alzheimer's disease biomarkers detection in human samples by efficient capturing through porous magnetic microspheres and labelling with electrocatalytic gold nanoparticles / De la Escosura Muñiz, Alfredo (Institut Català de Nanociència i Nanotecnologia) ; Plichta, Zdeněk (Akademie věd České republiky) ; Horák, Daniel (Akademie věd České republiky) ; Merkoçi, Arben (Institut Català de Nanociència i Nanotecnologia)
A nanobiosensor based on the use of porous magnetic microspheres (PMM) as efficient capturing/pre-concentrating platform is presented for detection of Alzheimer's disease (AD) biomarkers. These PMMs prepared by a multistep swelling polymerization combined with iron oxide precipitation afford carboxyl functional groups suitable for immobilization of antibodies on the particle surface allowing an enhanced efficiency in the capturing of AD biomarkers from human serum samples.

8 p, 1.6 MB Control of Electron-transfer in Immunonanosensors by Using Polyclonal and Monoclonal Antibodies / Mars, Abdelmoneim (Institut Català de Nanociència i Nanotecnologia) ; Parolo, Claudio (Institut Català de Nanociència i Nanotecnologia) ; De la Escosura Muñiz, Alfredo (Institut Català de Nanociència i Nanotecnologia) ; Raouafi, Noureddine (Université de Tunis El-Manar) ; Merkoçi, Arben (Institut Català de Nanociència i Nanotecnologia)
The design and operation of biosensors is not trivial. For instance, variation in the output signal during monitoring of analytes can not usually be controlled. Hence, if such control were possible, and could be triggered on demand, it would greatly facilitate system design and operation. [...]
