Spin-orbit and solvent effects in the luminescent [re6q8(ncs)6]4-, q=s, se, te clusters: molecular sensors and molecular devices

Indexación: ScieloRelativistic time-dependent density functional (TDDFT) calculations including spin orbit interactions via the zero order regular approximation (ZORA) and solvent effects using the COSMO model were carried out on the [Re6Q8(NCS)6]4- , (Q = S, Se, Te) clusters. These calculations indicate that the lowest energy allowed electronic transitions are characterized by being of LMCT type. The calculated absorption maximum tends to shift to longer wavelengths as the face-capping chalcogenide ligand becomes heavier. Thus our calculations predict that the [Re6Te8(NCS)6]4- cluster might be also luminescent. Due to the unusual properties exhibited by these and other isoelectronic and isostructural hexarhenium (III) chalcogenide clusters, hexamolybdenum halide clusters and hexatungsten halide clusters, we propose here the design of nanodevices, such as, molecular sensors and molecular nanocells for molecular electronics.http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-97072010000100010&nrm=is

Spreading of energy residential behavior; review of houses in south-central Chile

La necesidad de reducir los consumos de energía residencial requiere conocer cabalmente las condiciones habitacionales. Este artículo analiza viviendas en la zona Centro-Sur de Chile detectando una dispersión espacial de los comportamientos energéticos, que contrasta con la homogeneidad de las acciones públicas. Se presenta una revisión integral de cuarenta casos en el principal sector urbano de la zona (el área metropolitana del Gran Concepción) y se comparan con estadísticas y regionales y nacionales; revisando condiciones constructivas, de equipamiento ocupación, así como antecedentes gráficos y entrevistas, que reflejan una variedad formal y familiar, alejada de estereotipos y registros generales. Revelan una progresión habitacional y una diversidad de requerimientos energéticos. Proveyendo de este modo una estrategia de estudio que expresa la evolución residencial y puede ser aplicable a otras áreas, así como también otorgando nuevas visiones del comportamiento doméstico para enfrentar la crisis ambiental.La necessitat de reduir els consums d’energia residencial requereix conèixer cabdalment les condicions habitacionals. Aquest article analitza habitatges a la zona Centre-Sud de Xile, detectant una dispersió espacial dels comportaments energètics que contrasta amb l’homogeneïtat de les accions públiques. Es presenta una revisió integral de quaranta casos en el principal sector urbà de la zona (l’àrea metropolitana de Gran Concepció) i es comparen amb estadístiques regionals i nacionals; revisant condicions constructives, d’equipament ocupació, així com antecedents gràfics i entrevistes que reflecteixen una varietat formal i familiar, allunyada d’estereotips i registres generals. Proveint d’aquesta forma una estratègia d’estudi que expressa l’evolució residencial i pot ésser aplicable a altres àrees, així com també atorgant noves visions del comportament domèstic per afrontar la crisi ambiental.The need to reduce residential energy consumption necessitates full knowledge of housing conditions. This investigation analyzed dwellings in the south-central region of Chile. Spatial dispersion in energy behaviors was discovered, which contrasts with the homogeneity of public policy housing decisions. A comprehensive review is presented of forty houses in the Greater Concepcion Metropolitan Area, in comparison with national and regional statistics. An examination of building conditions and features, occupation data, photographic records and interviews, revealed formal and familial variety, which differ from stereotypes and general records. Findings demonstrate housing progression and diversity in energy needs. In this way, a research strategy was used that expresses residential evolution and can be applied in other areas, and provides a new vision of domestic behavior to confront the current environmental crisis.Peer Reviewe

Architectural and Management Strategies for the Design, Construction and Operation of Energy Efficient and Intelligent Primary Care Centers in Chile

Primary care centers are establishments with elevated social relevance and high operational energy consumption. In Chile, there more than 628 family healthcare centers (CESFAM) have been built in the last two decades and with plans for hundreds more in the next few years. We revised the architecture, construction management and energy performance of five CESFAM centers to determine possible instances of overall improvement. Staff was interviewed, and state documents reviewed, which allowed the conceptualization of the architectonic and energy structure of the centers, as well as the process of implementation. At the same time, energy simulations were done for each one of the centers, controlling for different climates, construction solutions and orientations. Our study revealed that strategies employed by the primary healthcare centers in Chile have aided a progressive implementation of establishments with elevated costs and materialization times, as well as neglect for climatic conditions. These energy evaluations show relevant and consistent impacts of the architectural form and material conditions, especially in southern zones, demonstrating the need to work with shared knowledge resources such as BIM. There is a clear necessity to define technological, morphological and construction strategies specific to each climate zone in order to achieve energetically efficient and intelligent healthcare establishments
