Synthesis of Binary and Ternary Metal Selenide Nanoparticles for Photocatalytic Applications: A Study of Molecule-to-Nanoparticles Transformation Mechanism
No full textSSCI-VIDE+CARE:CDFA+SGA:FDA:CGU:SMRInternational audienceTitanium dioxide (TiO2) is one of the most promising photocatalysts due to its low cost, non-toxicity, chemical stability and high catalytic activity. One limitation of this material is that it mainly absorbs in the UV region of the solar spectrum which represents only ~3.5% energy of total solar light. The catalytic efficiency of this material is further reduced by a relatively easy recombination of the photogenerated electron/hole. To overcome these intrinsic limitations, the current research focuses mainly on decreasing the band gap of titania by introducing some defects. This usually increases the wavelength range for the absorption but also decreases the activity for titania, thus resulting in no net gain. To improve the photocatalytic activity of TiO2, we are currently focusing on its nanocomposites with low bandgap metal chalcogenide semiconductors prepared mainly by the bottom-up approach [1,2]. This communication deals with precursor-mediated synthesis of binary and ternary coinage metal selenide nanoparticles under mild conditions. It will discuss different reaction conditions leading to different reactivities of starting reagents, affording either molecular complexes or inorganic nanoparticles directly. The preparation of nanocomposites of these metal selenide nanoparticles with commercial TiO2 (P25), their characterization by a range of physico-chemical techniques and photocatalytic activity for the degradation of formic acid under UV-visible radiation will be presented.References:[1] (a)Precursor-mediated synthesis of Cu2-xSe nanoparticles and its composites with TiO2 for improved photocatalysis, S.

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
