2H → 1T phase engineering of layered tantalum disulphides in electrocatalysis: oxygen reduction reaction
No full textTremendous attention is paid to renewable sources of energy. Transition metal dichalcogenides (TMDs) are intensively studied for their promising catalytic activities in hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR). In this fundamental work, we explore the catalytic properties of TMDs family members: 2H TaS2 and 1T TaS2. Our findings reveal that both polytypes exhibit poor HER performance which is even more pronounced when subjected to electrochemical treatment with reduction/oxidation. Our experimental data show that 1T TaS2 has a lower overpotential at a current density of -10 mA.cm-1, despite our theoretical density functional theory (DFT) calculations indicating that more favorable free energy of hydrogen adsorption should make perfect 2H TaS2 a better HER catalyst. By a thorough characterization, it is shown that the higher conductivity of 1T TaS2 and a slightly higher surface oxidation of 2H TaS2 explains this discrepancy. Moreover the changes in catalytic activity after electrochemical treatment are addressed here. For the oxygen reduction reaction (ORR) the electrochemical treatment leads to an improvement of catalytic properties. With onset potentials similar to that of Pt/C catalyst, TaS2 is found to be an efficient catalyst for oxygen reduction, rather than for proton reduction, in opposite to the behaviour of group VIB layered TMDs
Jack Alive / Martin Dead : The Location of the "Author" in Jack London\u27s Martin Eden
No full textThis essay is an attempt to read Martin Eden, Jack Londonʼs autobiographical novel, in terms of the inextricable relationship between the author and the protagonist. Critics have often taken the unbalanced plot and the lack of ironic distance between narrator and character in Martin Eden as the technical weakness of London, but this paper argues that the achievement of this novel owes a great deal to the attachment of London to Martin. The unbalanced structure is a necessary product of the severe struggle of the author to kill his romantic alter ego. // Martin, who aspires to win Ruth Morse, tries to cross class boundaries by making a career of a writer. Even after realizing the emptiness of Ruth, who turns out to be nothing but a typical figure of the bourgeoisie, he somehow persists in loving her. The notion underlying here is that, for Martin, love, career and art are fundamentally inseparable. He objects to the aestheteʼs view of Brissenden on account of his separation of art from career. Martinʼs identity and life consist only in the triunity of love/career/art; the alternative is the repudiation of life. Thus, the unnatural delay of his disappointment in love can be regarded as Londonʼs strategy to set the suicide of Martin as the necessary consequence of the story. // By finishing the story and killing Martin, London finally detaches himself from Martin, reconstructs his self, and, unlike Martin, survives as a professional writer. In this sense, Martin Eden is a story about “writerʼs self-reconstruction.

Experiences Using Large Scale Video Walls for Distance Education
No full textWe describe our experiences building and using the Rutgers Videowall, a low-cost telepresence system that has been used teaching 15 courses and colloquia. By relaxing typical spatial telepresence features, such as background continuity, we greatly reduced costs and gained flexibility in the rooms it could be deployed in. The lower costs and room flexibility enabled academic departments to use the wall, in contrast to traditional telepresence systems which remained inaccessible. We found that the Videowall’s spatial distortions did not have a significant impact on useability, as our initial survey results show that students had an overall positive experience.Technical report DCS-tr-72
