“…By use of this technique polycrystalline AgMo6S8 films with thicknesses ranging from 0.5 to 1 ixm were obtained. We should also mention that films of AgMo6S8 as thin as 1000A, whose electrochemical behavior will be reported elsewhere, were recently prepared by a novel reactive sputtering technique (13).…”

Interest in examining the electrochemical insertion of lithium into framework crystal structures has arisen recently because of electrolyte limitations associated with the cointercalation of organic solvents encountered with other low dimensional intercalation materials (i.e., compounds built up of layers or chains of atoms) such as the layered transition metal dichalcogenides. Several materials with framework structures have been studied with most of the attention focused on the binary Chevrel phase Mo6Sa which was found to reversibly accommodate four lithium atoms per unit formula resulting in a theoretical energy density of 280 Wh/kg. However, difficulties in preparing this phase by conventional means have hindered its synthesis and subsequent use in secondary lithium cells. In this paper we give evidence from electrochemical and in situ x-ray studies that AgMo6S8 can be electrochemically converted to Mo~S8 plus silver metal and then

“…no signs of concomitant HIV infection or genetic causes of severe immunodeficiency), the immune systems of neonates and infants are immature with suboptimal responses to infections and vaccines [43,44]. Viral adrenalitis in primary immunodeficiencies have also been described, including adrenal insufficiency caused by Epstein-Barr virus (EBV) infection in an adolescent with Wiscott-Aldrich syndrome and subclinical adrenal CMV infection discovered at autopsy in children with severe combined immunodeficiency [45,46]. However, some of the viruses described above, including HSV-1 and CMV, have also been associated with adrenalitis in apparently immunocompetent adults [29,47,48].…”

Autoimmune Addison's disease (AAD), or primary adrenocortical insufficiency, is a classical organ-specific autoimmune disease with 160 years of history. AAD is remarkably homogeneous with one major dominant self-antigen, the cytochrome P450 21-hydroxylase enzyme, which is targeted by both autoantibodies and autoreactive T cells. Like most autoimmune diseases, AAD is thought to be caused by an unfortunate combination of genetic and environmental factors. While the number of genetic associations with AAD is increasing, almost nothing is known about environmental factors. A major environmental factor commonly proposed for autoimmune diseases, based partly on experimental and clinical data and partly on shared pathways between anti-viral immunity and autoimmunity, is viral infections. However, there are few reports associating viral infections to AAD, and it has proved difficult to establish which immunological processes that could link any viral infection with the initiation or progression of AAD. In this review, we will summarize the current knowledge on the underlying mechanisms of AAD and take a closer look on the potential involvement of viruses.

“…The constituting elements were deposited epitactically, monolayer after monolayer and converted into the desired semiconductor 243, 244. The synthetic relevance finally stepped into the foreground in the context of the creation of thin films of superconducting chevrel phases from the elements 245, 246. To achieve this result, UHV‐chambers were constructed, in which the constituent metals were evaporated, either in a H 2 S atmosphere or together with elementary sulfur, and made to react on a heated substrate (∼800 °C).…”

There is a widely-held belief that the preparation of new solid-state compounds based on rational design is not possible. Herein, we present a concept that points the way towards a rational design of syntheses in solid-state chemistry. The foundation of our approach is the representation of the whole material world, that is, the known and not-yet-known compounds, on an energy landscape, which gives information about the free energies of these compounds. From this it follows that all chemical compounds capable of existence are present on this landscape. Thus the chemical synthesis always corresponds to the discovery of compounds, not their creation. Consequently, the first step in planning a synthesis can and must be to identify a synthesizable compound. Up to now, materials capable of existence are discovered in the course of an experimental exploration of the energy landscape; however, an a priori identification of a synthesis goal requires an exploration using theoretical methods. In contrast to those computational approaches currently employed for structure determination for fixed composition and already known unit cells, our aims clash with such restrictions and full global optimizations have to be performed on the landscape. Although for reasons of computational feasibility the accuracy of the energy calculations is not yet as high as one would wish, our approach proves to be surprisingly robust. One always finds the already known compounds of a given chemical system, and, in addition, further plausible structure candidates are discovered. The second step of a rational planning of syntheses is the design of feasible synthesis routes. Modeling such routes requires highly accurate computations for realistic thermodynamic conditions, however this is usually beyond our current capabilities. Thus, we have not seriously pursued such a deductive approach; instead we have attempted, to reproduce the "computational annealing" employed during our structure predictions in the experiment. Educts, generated by vapor deposition methods, that are disperse on an atomic level are found to react with surprisingly low activation energies to give highly crystallized products. However, even this technique does not yet provide the possibility to selectively synthesize a specific solid compound. For this final step, modeling and experimental control of nucleation processes will be the key ingredient. Only when viewed superficially, our goal of a "rational design" of solid-state syntheses and the "high-throughput" syntheses are in contradiction. But an exhaustive exploration of the unimaginably large combinatorial diversity of chemistry remains beyond our capabilities, even with an exceedingly high throughput. The future of solid-state synthesis will be found in a union of these two conceptual approaches.
