Hall mobility in doped Si:H,Cl films.
No full textThe Hall mobility μH in phosphorus- and boron-doped Si:H, Cl films was measured in the temperature range 130–300 K. The conductivity is markedly influenced by the doping, and the activation energies of both the Hall mobility and the conductivity as functions of the temperature are much lower in doped samples than in undoped samples. The process tends to become unactivated at higher doping levels
Hall mobility in undoped microcrystalline Si:H,Cl films.
No full textThe Hall mobility in undoped microcrystalline Si:H, Cl films has been measured in the temperature range
130<T<300K. The dependence of μH on the temperature clearly evidences two different transport mechanisms. Above T0=200 K, the Hall mobility has an activation energy of about 0.3 eV, while below T0 it is practically temperature independent

Transition metal polyhydride complexes. 10. Intramolecular hydrogen exchange in the octahedral iridium(III) dihydrogen dihydride complexes IrXH(2)(eta(2)-H(2))(PR(3))(2) (X = Cl, Br, I)
No full textDensity functional calculations (B3LYP) on IrXH(2)(eta(2)-H(2))(PR(3))(2) for X = Cl, Br, I and R = H, Me and inelastic neutron scattering studies for X = Cl, Br, I and R = Pr(i) are used to elucidate the mechanisms for the intramolecular dihydrogen/hydride exchange. The two lowest energy processes are rotation of the dihydrogen ligand and oxidative addition of the dihydrogen to form an intermediate Ir(V) tetrahydride, which undergoes rapid reductive elimination to interchange the dihydrides and the dihydrogen. The use of PMe(3) as a model phosphine is essential to bring the calculated barriers for the dihydrogen/hydride interchange into agreement with the experimental observations. The activation energy for site exchange (1.9 kcal/mol) is found to be in excellent agreement with the experimental result obtained for X = Cl (1.5(2) kcal/mol), and the calculations show a slight decrease in this value from X = C1 to I. Comparison between calculated rotational barriers (0.3 to 0.7 kcal/mol) and experimental values obtained for IrXH(2)(eta(2)-H(2))(PR(3))(2) (X = Cl, Br, I; R = Pr(i)) (0.5 to 1.0 kcal/mol) also demonstrates that the quantitative estimate of the barrier to rotation requires PMe(3) as the minimal model ligand
Open access self-archiving: An author study
No full textThis, our second author international, cross-disciplinary study on open access had 1296 respondents. Its focus was on self-archiving. Almost half (49%) of the respondent population have self-archived at least one article during the last three years. Use of institutional repositories for this purpose has doubled and usage has increased by almost 60% for subject-based repositories. Self-archiving activity is greatest amongst those who publish the largest number of papers. There is still a substantial proportion of authors unaware of the possibility of providing open access to their work by self-archiving. Of the authors who have not yet self-archived any articles, 71% remain unaware of the option. With 49% of the author population having self-archived in some way, this means that 36% of the total author population (71% of the remaining 51%), has not yet been appraised of this way of providing open access. Authors have frequently expressed reluctance to self-archive because of the perceived time required and possible technical difficulties in carrying out this activity, yet findings here show that only 20% of authors found some degree of difficulty with the first act of depositing an article in a repository, and that this dropped to 9% for subsequent deposits. Another author worry is about infringing agreed copyright agreements with publishers, yet only 10% of authors currently know of the SHERPA/RoMEO list of publisher permissions policies with respect to self-archiving, where clear guidance as to what a publisher permits is provided. Where it is not known if permission is required, however, authors are not seeking it and are self-archiving without it. Communicating their results to peers remains the primary reason for scholars publishing their work; in other words,
researchers publish to have an impact on their field. The vast majority of authors (81%) would willingly comply with a mandate from their employer or research funder to deposit copies of their articles in an institutional or subject-based repository. A further 13% would comply reluctantly; 5% would not comply with such a mandate
Progress of international hydrogen production network for the thermochemical Cu–Cl cycle
No full textThis paper presents recent advances by an international team which is developing the thermochemical copper–chlorine (Cu–Cl) cycle for hydrogen production. Development of the Cu–Cl cycle has been pursued by several countries within the framework of the Generation IV International Forum (GIF) for hydrogen production with the next generation of nuclear reactors. Due to its lower temperature requirements in comparison with other thermochemical cycles, the Cu–Cl cycle is particularly well matched with Canada's Generation IV reactor, SCWR (Super-Critical Water Reactor), as well as other heat sources such as solar energy or industrial waste heat. In this paper, recent developments of the Cu–Cl cycle are presented, specifically involving unit operation experiments, corrosion resistant materials and system integration.Atomic Energy of Canada LimitedOntario Research Excellence FundNatural Sciences and Engineering Research Council of CanadaUniversity Network of Excellence in Nuclear Engineering (UNENE)Canada Research Chairs progra

ŻYCIE UKRYTE W SŁOWIE. "BEKSIŃSCY. PORTRET PODWÓJNY" MAGDALENY GRZEBIAŁKOWSKIEJ W ŚWIETLE POSTSTRUKTURALIZMU
No full textLife Hidden in Words. Magdalena Grzebiałkowska\u27s "Beksińscy. Portret podwójny" and Poststructuralism
The article analyzes Magdalena Grzebiałkowska\u27s biographical "Beksińscy. Portret podwójny" which focuses on the lives of Zdzisław Beksiński and Tomasz Beksiński. The author looks at the construction of the biography and its relationship to poststructuralism, which allows for an appreciation of the literary features of the book. He points to how the specificity of the content, language, a mode of narration in Grzebiałkowska\u27s book make it a full-fledged literary work itself. As such the book departs from a typical biographical scheme. Juxtaposing the book with poststructural ideas leads to the reconsideration of the role of the author in the process of shaping of a biographical narrative
