Multihierarchical electrodes based on titanate nanotubes and zinc oxide nanorods for photoelectrochemical water splitting
No full textStudies involving water splitting to form hydrogen and oxygen have attracted attention because H2 is considered the fuel of the future. Photoelectrocatalysts have been widely used for this application, and several metal oxides can be applied as catalysts. Among them, we highlight zinc oxide nanorods (ZnONRs) and titanate nanotubes (TiNTs); however, their individual nanostructures exhibit disadvantages. For example, ZnONR shows rapid recombination of the photogenerated charges, and TiNT gives rise to randomly orientated films; these disadvantages limit their application as photoanodes. In this study, for the first time, we present a new class of multihierarchical electrodes based on TiNT-decorated ZnONR films that exhibited superior results to the individual species. The TiNTs are homogenously dispersed over the surface of the rods without forming agglomerates, giving rise to a heterojunction that exhibits lower recombination rates. It was found that the results are better when the contents of TiNT in the electrode are higher; thus, glycine was successfully used as a bridge to link both of the structures, increasing the amount of TiNT decorating the rods. As a result, the photocurrent generated with these multihierarchical electrodes is higher than that obtained for pure ZnONR electrodes (0.9 mA and 0.45 mA, respectively), and the electrode potentials for O2 evolution is lower than that observed for pure TiNT electrodes (0 V and 0.8 V vs. ERHE, respectively). The IPCE values are also higher for the multihierarchical electrodes
Vibrio Variabilis Sp. Nov. And Vibrio Maritimus Sp. Nov., Isolated From Palythoa Caribaeorum
No full textTwo novel vibrio isolates (R-40492 T and R-40493 T) originating from the zoanthid Palythoa caribaeorum in Brazil in 2005 were taxonomically characterized by means of a polyphasic approach comprising multilocus sequence analysis (MLSA), DNA-DNA hybridization (DDH), ΔTm analysis and phenotypic characterization. Phylogenetic analysis based on 16S rRNA gene sequences showed that R-40492 T and R-40493 T fell within the genus Vibrio and were most closely related to each other with 99% similarity; similarities of these two novel isolates towards Vibrio neptunius LMG 20536 T, Vibrio coralliilyticus LMG 20984 T, Vibrio nigripulchritudo LMG 3896 T, Vibrio sinaloensis LMG 25238 T and Vibrio brasiliensis LMG 20546 T varied between 97.1 and 98.5%. DDH experiments showed that the two isolates had less than 15% relatedness to the phylogenetically most closely related Vibrio species. R-40492 T and R-40493 T had 55-57% relatedness to each other. The ΔTm between R-40492 T and R-40493 T was 6.12 °6C. In addition, MLSA of concatenated sequences (16S rRNA, ftsZ, gyrB, recA, rpoA, topA, pyrH and mreB; 6035 bp in length) showed that the two novel isolates formed a separate branch with less than 92% concatenated gene sequence similarity towards known species of vibrios. Two novel species are proposed to accommodate these novel isolates, namely Vibrio variabilis sp. nov. (type strain, R-40492 T=LMG 25438 T=CAIM 1454 T) and Vibrio maritimus sp. nov. (type strain, R-40493 T=LMG 25439 T=CAIM 1455 T)., © 2011 IUMS.611230093015Baumann, P., Schubert, R.H.W., Genus I.Vibrio.In Bergey's Manual of Systematic Bacteriology (1984), 1, pp. 518-538. , Edited by N.

An empirical relationship between the Deacon profile number and the Richardson number under convective conditions
No full textMean low-level temperature and wind profiles were constructed for 44 cases of free convection using the data O'Neill, Nebraska, during July and August 1956. Based upon the expression for the normalized logarithmic wind shear first suggested by Ellison and later refined by Panofsky, a theoretical formula for the Deacon number as a function of the Richardson number was derived, and values of the Deacon profile were computed. One of the parameters entering into this formula is the ration of the eddy diffusitivities for heat and momentum. This parameter was, in turn, computed from Priestley's expression for the dimensionless heat flux for free-convective cases. In using observed wind data from the mean profile in order to verify the theoretical computations of B, some marked discrepancies
occurred above the 100 cm level. These were due to inconsistent wind speed readings, and it was necessary to employ control data, based on neutral profiles to correct the wind speed. When this was done, the theoretical and
observed Deacon profile nurnbers were in very good agreement.

Rotterdam: A dynamic polder city in the Randstad
No full textThis chapter examines the case of Rotterdam as one of the most representative cities in the Randstad in dealing with water and adapting to the current challenges. The dynamics of the regional water system, which include groundwater and rainwater in combination with surface water in a lowland delta facing the North Sea, is crucial for the process of development and urbanisation of the Dutch polders. By creating the Waterstad area, Rotterdam took profit from its strategic position in the Randstad Delta. Van der Ham described eighth century period of time until the year 1000 as distinguished by ‘natural water management’, as nature ruled over culture. At the end of the nineteenth century, explosive urbanisation and technological prosperity put pressure on the polder cities. The manipulative era is marked by the introduction of the engine and electricity, which had an immense influence on the city and the water system.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Environmental Technology and Desig
