Janus electrochemistry: asymmetric functionalization in one step

Janus structures represent an overwhelming member of materials with adaptable chemical and physical properties. Development of new synthesis routes has allowed the fabrication of Janus architectures with specific characteristics depending on the final applications. In the case of the membranes, the improvement of wet routes has been limited to the capillary effect, in which the solution can gradually penetrate through the membrane, avoiding a double modification different at each face of the membrane. In this work, we propose a new electrochemical methodology to circumvent the capillary limitation and obtain a double electrochemical functionalization in only one step in a controlled way. This innovative methodology has been validated using a tridirectional spectroelectrochemistry setup. Moreover, the information provided by this optical arrangement should be especially useful for the study of the different processes (ion transfer, assisted ion transfer, and electron transfer) that can take place at liquid/liquid interfaces. Janus electrochemistry allows us to modify the two faces of a free-standing single-walled carbon nanotube electrode in a single experiment. As proof of concept, the free-standing films have been functionalized with two different conducting polymers, polyaniline and poly(3-hexylthiophene), in one electrochemical experiment. According to the obtained results, this new electrochemical methodology will open new gates for the design and functionalization of Janus materials.Ministerio de Economía y Competitividad (Grants CTQ2014-61914-EXP, CTQ2014-55583-R, TEC2014-51940-C2-2R, and CTQ2015-71955-REDT) and Junta de Castilla y León (Grant BU033-U16

Silver nanoparticles/free-standing carbon nanotube Janus membranes

Janus materials are attracting intense interest due to their exceptional possibilities in the design of structures with specific properties. In this work, Janus structures were constructed by the functionalization of free-standing single-walled carbon nanotube (FS-SWCNT) membranes with silver nanoparticles (AgNPs) electrodeposited on one face of the free-standing structure. The modification of the FS-SWCNT films with AgNPs was carried out from an ionic liquid solution, a green and environmentally friendly procedure. Before the functionalization of the free-standing membranes, the optimal electrodeposition conditions of AgNPs from an ionic liquid in different carbon substrates were studied. We demonstrate by UV–vis spectroelectrochemistry that the functionalization of the FS-SWCNT membranes on only one face is achieved, remaining unmodified the other face, as SEM images confirm. Moreover, the morphology of AgNPs, and, consequently, the properties of the Janus structures strongly depend on the specific electrodeposition conditions selected, determining their future applicability.Ministerio de Economía y Competitividad (CTQ2014-61914-EXP, CTQ2014-55583-R, TEC2014-51940-C2-2R, CTQ2015-71955-REDT) and Junta de Castilla y León (BU033-U16)Ministerio de Economía y Competitividad (CTQ2014-61914-EXP, CTQ2014-55583-R, TEC2014-51940-C2-2R, CTQ2015-71955-REDT) and Junta de Castilla y León (BU033-U16

All-Path Bridging: Path Exploration Protocols for Data Center and Campus Networks

Today, link-state routing protocols that compute multiple shortest paths predominate in data center and campus networks, where routing is performed either in layer three or in layer two using link-state routing protocols. But current proposals based on link-state routing do not adapt well to real time traffic variations and become very complex when attempting to balance the traffic load. We propose All-Path bridging, an evolution of the classical transparent bridging that forwards frames over shortest paths using the complete network topology, which overcomes the limitations of the spanning tree protocol. All-Path is a new frame routing paradigm based on the simultaneous exploration of all paths of the real network by a broadcast probe frame, instead of computing routes on the network graph. This paper presents All- Path switches and their differences with standard switches and describes ARP-Path protocol in detail, its path recovery mechanisms and compatibility with IEEE 802.1 standard bridges. ARP-Path is the first protocol variant of the All-Path protocol family. ARP-Path reuses the standard ARP Request and Reply packets to explore reactively the network and find the fastest path between two hosts. We compare its performance in terms of latency and load distribution with link-state shortest-path routing bridges, showing that ARP-Path distributes the load more evenly and provides lower latencies. Implementations on different platforms prove the robustness of the protocol. The conclusion is that All-Path bridging offer a simple, resilient and scalable alternative to path computation protocols

Análisis preliminar de la situacion actual en Italia sobre residuos de construcción y demolición (C&D): Desafíos y oportunidades

[ES] El volumen de residuos procedentes de la Construcción y Demolición en Europa aumenta cada año, la Unión Europea ha decidido tomar el control del asunto recojiendouna prácticas y objetivos comunes a alcanzar. Este artículo analiza cómo funciona la gestión de residuos en Italia ajustando su sistema a la Unión Europea, en materia de Construcción y Demolición, teniendo en cuenta la disposición de material procedente de la producción de C&D (Construction and Demolition). En Italia, la disposición puede diferir SEGÚN las regiones en las que se divide, y esto debe tenerse en cuenta a la hora de analizar información que refleje los distintos aspectos logísticos vinculados al territorio. También es necesario considerar cómo el volumen de residuos puede variar SEGÚN el tamaño de la región considerada y el tipo de desarrollo industrial al que pertenece. El análisis de la situación italiana muestra sus logros respecto la canti- dad de residuos C&D reciclados que después del 2010 alcanza un valor igual o superior al mínimo establecido por la Union Europea, aunque todavía existen barreras en el campo de su gestión. A través de la recolección de datos, se ha visto el diferente volumen que se genera en las actividades relacionadas con la construcción en el país, junto con el volumen de residuos recuperados. Así, el objetivo de este trabajo es profundizar en el conocimiento general sobre los residuos producidos por la Construcción y Demolición en Italia y las prácticas de gestión de residuos adoptadas SEGÚN la Unión Europea.This work was supported by the European Union under the framework of Condereff project (Ref.

Longitudinal Study of Therapeutic Adherence in a Cystic Fibrosis Unit: Identifying Potential Factors Associated with Medication Possession Ratio

Cystic fibrosis (CF) is a genetic and multisystemic disease that requires a high therapeutic demand for its control. The aim of this study was to assess therapeutic adherence (TA) to different treatments to study possible clinical consequences and clinical factors influencing adherence. This is an ambispective observational study of 57 patients aged over 18 years with a diagnosis of CF. The assessment of TA was calculated using the Medication Possession Ratio (MPR) index. These data were related to exacerbations and the rate of decline in FEV1 percentage. Compliance was good for all CFTR modulators, azithromycin, aztreonam, and tobramycin in solution for inhalation. The patients with the best compliance were older; they had exacerbations and the greatest deterioration in lung function during this period. The three variables with the highest importance for the compliance of the generated Random Forest (RF) models were age, FEV1%, and use of Ivacaftor/Tezacaftor. This is one of the few studies to assess adherence to CFTR modulators and symptomatic treatment longitudinally. CF patient therapy is expensive, and the assessment of variables with the highest importance for a high MPR, helped by new Machine learning tools, can contribute to defining new efficient TA strategies with higher benefits
