Geometric and electronic aspects of the dissociative chemisorption of hydrogen and nitrogen on metal surfaces
No full textThe effect of geometric and electronic modifications on the dissociative chemisorption of hydrogen and nitrogen has been studied on single crystal surfaces and through the reactivity of catalysts. The role of the promoters in iron based ammonia catalysts has been shown to be very sensitive to the presence of surface adsorbates. Alumina is seen to stabilize a surface reconstruction to a more active geometry, producing a hysteresis in the reactivity during heating and cooling experiments. This reconstruction is believed to be induced by adsorbed nitrogen, the coverage of which increases rapidly with the partial pressure of ammonia. Potassium has very little effect on the reaction rate at low nitrogen coverages, but as this increases with the rate of synthesis, significant promotion is observed. This is explained through an increased removal of Nads as ammonia, freeing sites for further reaction, rather than previous models of directly promoted nitrogen dissociation. The oxidation and reduction of the surface causes a rapid reconstruction, producing a large but transient desorption of ammonia. On the promoted samples, the oxygen blocks all reaction, but on pure iron actually produces a more active surface. The dynamics of dissociative adsorption of hydrogen on the W(100)-c(2x2)Cu and W(100)-c(2x2)N surfaces has been studied under UHV conditions with a supersonic molecular beam. On both surfaces an indirect channel exists, very similar to that on W(100). This is believed to be due to the dissociation at defects, such as steps, of an essentially tungsten nature.</p

Why is 'City of Death' the best Doctor Who story?
No full textTime and Relative Dissertations in space takes the reader on a rich and varied study of one of the greatest television programmes of all time: Doctor Who. \ud
This book is the first study of Doctor Who to explore the Doctor's adventures in all their manifestations: on television, audio, in print and beyond. Although focusing on the original series (1963–89), the collection recognises that Doctor Who is a cultural phenomenon that has been 'told' in many ways through a myriad of texts.\ud
Combining essays from academics as well as practitioners who have contributed to the ongoing narrative of Doctor Who, the collection encourages debate with contrasting opinions on the strengths (and weaknesses) of the programme, offering a multi-perspective view of the Doctor and the reasons for his endurance
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“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
