On-Surface Synthesis International Workshop (OSS20) On-Surface Synthesis International Workshop (OSS20)
On-Surface Synthesis International Workshop (OSS20)
On-surface synthesis unites the easy tunability of molecular materials and the promises of self-assembly as a revolutionary production method, with the sturdiness of covalently bonded structures. This most attractive combination is drawing the interest of a rapidly increasing number of researchers. Important efforts are being devoted to augment the available on-surface synthesis toolbox, to improve our understanding of the chemical reaction mechanisms, as well as to the synthesis and characterization of new molecular archi ...

In MEMORIAM: José Luis de Segovia Trigo, una vida dedicada a la ciencia y tecnología de vacío
El 13 de noviembre de 2019 falleció nuestro querido amigo y compañero José Luis de Segovia, una personalidad de referencia en la ciencia y tecnología de vacío en España. José Luis disfrutó de una Beca “Fulbright” entre los años 1962-1964 en la universidad de Illinois (USA) donde trabajó con Daniel Alpert, diseñador del manómetro de ionización con el que se puede considerar que comenzó la tecnología de ultra-alto vacío. De vuelta a España trajo esta tecnología a nuestro país y se construyeron las primeras cámaras de vidrio ...

NANOCOSMOS: un viaje desde las estrellas al nanomundo - Lidia Martínez
Hace unos años, tres científicos europeos, se embarcaron en un viaje desde las estrellas hacia el laboratorio. Christine Joblin, José Cernicharo y Jose Ángel Martín Gago, tuvieron la idea de crear un espacio en el que compartir sus conocimientos en distintas disciplinas de la ciencia con una meta común: entender el origen del polvo cósmico. Con esa idea nació el proyecto Gas y polvo de las estrellas al laboratorio: explorando el NANOCOSMOS. Combinando observaciones radioastronómicas con experimentos en el laboratorio, se t ...

Xabier García Casas - Panspermia
Panspermia Esta es la historia de un meteoroide que vagaba por aquí y por allá; siempre en movimiento, pero siempre en soledad. Cruzando nubes de polvo, vacíos de eternidad, siguiendo su camino, siempre sin mirar atrás. Formado a millones de parsecs, ¿qué  tenía de especial? ¿No era acaso como otros astros, una roca y nada más? Tan solo hecho de polvo y roca, roca y hielo glacial le gustaba acercarse a estrellas, pasar a toda velocidad casi a ras de su superficie, ¡menuda temeridad! para así formar una hermosa cola, de ext ...

Physically Unclonable Functions Based on Single-Walled Carbon Nanotubes: A Scalable and Inexpensive Method toward Unique Identifiers

Author: Enrique Burzurí, Daniel Granados, Emilio M. Pérez

ACS Appl. Nano Mater. (2019

A physically unclonable function (PUF) is a physical system that cannot be reproduced or predicted and therefore is a good basis on which to build security and anticounterfeiting applications. The unclonability of PUFs typically stems from the randomness induced…
