Epilogue

By the time Tommy Tune received a special Tony Award for Lifetime Achievement in 2015, he had inspired a new generation of director-choreographers, including Susan Stroman, Jerry Mitchell, and Casey Nicholaw. They successfully adapted Tune’s seamless staging concepts, his use of show business motifs, and his ability to move forward by drawing on the past to a new, faster-paced era. Well into his seventies, Tune continued to create shows with precision and detail, but now they were of a much smaller scale and featured a cast of one. His solo traveling act took on a biographical air, with recollections of his theatrical past performed on a bare stage with just a small platform for dancing, a ladder, and evocative lighting. It was the simplicity and elegance of Nine, Grand Hotel, and My One and Only stripped to their most elemental form. For Tune, everything was still choreography, but on a diminutive scale.

Impossible Origins: Trauma Narrative and Cinematic Adaptation

In this essay, I explore the cinematic adaptation and the representation of trauma, while I further consider the role and significance of the notion of the origin in both trauma and in cinematic adaptation. Through an initial consideration of the relationship between the theory of the impossible origin, particularly as it is articulated by Walter Benjamin, the essay goes on to analyze the significance and role of an impossible origin in the elemental form of adaptation. To this end, the essay considers the movement of adaptation from an autobiographical trauma memoir to a feature film, considering the success or failure of adaptation in situations where the original literary work concerns an experience of extremity. As I consider the vicissitudes of trauma and its grounding in a repetitious structure that leaves the survivor suspended in a kind of missed experience (or missed origin), I further explore how this missing origin (or original text in the case of adaptation) can be represented at all.

Recent advances in effective capture of inorganic mercury from aqueous solutions through sulfurized 2D-material-based adsorbents

The inorganic form of mercury is considerably dangerous because of its highly volatile elemental form, exposure to which causes many serious health challenges including nervous system and lung damages as...

Photochemistry of oxidized Hg(I) and Hg(II) species suggests missing mercury oxidation in the troposphere

Mercury (Hg), a global contaminant, is emitted mainly in its elemental form Hg0to the atmosphere where it is oxidized to reactive HgIIcompounds, which efficiently deposit to surface ecosystems. Therefore, the chemical cycling between the elemental and oxidized Hg forms in the atmosphere determines the scale and geographical pattern of global Hg deposition. Recent advances in the photochemistry of gas-phase oxidized HgIand HgIIspecies postulate their photodissociation back to Hg0as a crucial step in the atmospheric Hg redox cycle. However, the significance of these photodissociation mechanisms on atmospheric Hg chemistry, lifetime, and surface deposition remains uncertain. Here we implement a comprehensive and quantitative mechanism of the photochemical and thermal atmospheric reactions between Hg0, HgI, and HgIIspecies in a global model and evaluate the results against atmospheric Hg observations. We find that the photochemistry of HgIand HgIIleads to insufficient Hg oxidation globally. The combined efficient photoreduction of HgIand HgIIto Hg0competes with thermal oxidation of Hg0, resulting in a large model overestimation of 99% of measured Hg0and underestimation of 51% of oxidized Hg and ∼66% of HgIIwet deposition. This in turn leads to a significant increase in the calculated global atmospheric Hg lifetime of 20 mo, which is unrealistically longer than the 3–6-mo range based on observed atmospheric Hg variability. These results show that the HgIand HgIIphotoreduction processes largely offset the efficiency of bromine-initiated Hg0oxidation and reveal missing Hg oxidation processes in the troposphere.

Promising methods for hydrogen producing

Hydrogen production is one of the most promising ways to develop the energy sector of the future. Hydrogen does not exist in nature in its elemental form and therefore, it must be obtained from hydrocarbon, water or any other hydrogen-containing compounds. The variety of potential sources of raw materials for hydrogen production is one of the important reasons, in which hydrogen is such a promising energy carrier. The article describes methods for preparing the basic energy carrier, hydrogen from natural gas, ethanol etc. Among various types of raw materials, bioethanol is very attractive because of its relatively high hydrogen content, availability, as well as safety during storage and handling.

Conclusion

From its early emergence in the discourse of classical antiquity to its expression in contemporary democratic life, autonomy has proven to be a gripping and engaging prospect. But the expansion of personal autonomy casts a long shadow across democracies, fostering unhealthy, morally defective understandings of the nature and limits of individual self-rule. Vaunted in philosophical scholarship and celebrated in the democratic mind, personal autonomy proves excessively lax in a normative sense, faulty and unworthy of endorsement in its elemental form. That problem cannot be solved by ignoring autonomy’s sinister side or by imagining personal autonomy as a singularly positive condition. Autonomy for individual human persons requires qualification and tighter moral specification in order to be worthy of endorsement and allegiance....

Effect of aging on properties and nanoscale precipitates of Cu-Ag-Cr alloy

In this paper, the Cu-0.52Ag-0.22Cr alloy was prepared by hot horizontal continuous casting. The effects of aging process on micro-hardness, electrical conductivity, and nanoscale precipitates of Cu-0.52Ag-0.22Cr alloy were studied. The electrical conductivity and micro-hardness increase significantly in the early aging time. With the extension of aging time, the electrical conductivity is basically unchanged and remains at a high level. While, the micro-hardness increases slowly, the change trend is different at 623 K, 723 K, and 773 K. The optimisation of process parameters occurs in 723 K for 2 h. At this time, the electric conductivity is 95.8% IACS and the hardness is 104.1 HV0.1. The XRD result shows that the Ag and Cr are precipitated in elemental form copper matrix. Further TEM shows that, Cr exists at the sub-boundary in the form of larger nanoscale precipitates (100-200 nm). While a large number of Ag nanoscale precipitates (8-10 nm) is dispersed on the copper matrix. The synergistic effect of Ag and Cr nanoscale precipitates significantly improved the properties of the alloy.

Uranium targets for heavy-ion accelerators

Uranium targets are very important for accelerator-based research of nuclear properties. Depending on the reaction to be studied and on the conditions during the experiments different restrictions on the target material have to be met; as for example, durability, melting temperature, reactivity or a possible contribution of the additional compounds present to the reaction. Therefore, we are developing processes to produce uranium targets in the elemental form as well as in different compounds. Here we report on the production and application of targets from metallic uranium, UF4 and UO2.

Formation of Si Nanorods and Discrete Nanophases by Axial Diffusion of Si from Substrate into Au and AuPt Nanoalloy Nanorods

Interdiffusion between Si substrate and nanorod arrays of Au, Pt, and AuPt nanoalloys is investigated at temperatures lower than the AuSi eutectic temperature. When the nanorod is pure Au, Si diffusion from the substrate is very rapid. Au atoms are completely replaced by Si, converting the nanostructure into one of Si nanorod arrays. Au is diffused out to the substrate. The Au nanorod arrays on Si are unstable. When the nanorod is pure Pt, however, no diffusion of Si into the nanorod or any silicide formation is observed. The Pt nanorods are stable on Si substrate. When the nanorods are an alloy of AuPt, interesting interactions occur. Si diffusion into the nanorods is rapid but the diffusing Si readily reacts with Pt forming PtSi while Au diffuses out to the substrate. After annealing, nanophases of Au, Pt, PtSi, and Si may be present within the nanorods. When the Pt content of the alloy is low (12 at%) all Pt atoms are converted to silicide and the extra Si atoms remain in elemental form, particularly near the tip of the nanorods. Hence, the presence of Au accelerates Si diffusion and the ensuing reaction to form PtSi, a phenomenon absents in pure Pt nanorods. When the Au content of the alloy is low, the Si diffusion would cease when all Au atoms have diffused out of the nanorod, thereby arresting the silicide formation resulting in excess Pt in elemental form within the nanorod. This is a technique of making Si nanorods with and without embedded PtSi nanophase consisting of heterojunctions which could have unique properties.
