Abstract The thermodynamics of the Pt–Sn system is revisited with attention to phase equilibria involving PtSn4, a topological quantum material interesting physical properties. relationship in Sn-rich region binary was investigated by combination differential scanning calorimetry and equilibration experiments. Based on present experiments critical evaluation available thermodynamic diagram data...

Compressed air energy storage system is a promising solution in the field: it characterized by high reliability, low environmental impact and remarkable density. This study focuses on two of advanced technologies isothermal compressed systems developed LightSail Energy (mechanical piston with water injection) Enairys Powertech (liquid integrated heat exchanger). A first numerical model based th...

This study presents for the first time a systematic investigation of thermodynamic properties sodium aluminosilicate hydrate (N–A–S–H), through dissolution pure synthetic N–A–S–H gels.

BACKGROUND To our knowledge, no study has assessed the validity of family history data provided by probands with adult-onset dystonia. OBJECTIVE To measure the sensitivity and specificity of interviewing patients with primary adult-onset dystonia as a method for obtaining information on dystonia in first-degree relatives. PARTICIPANTS Seventy probands with primary adult-onset dystonia were ...

BACKGROUND The aim was to compare tuberculosis trends in Mexico and United States and to evaluate Mexican diagnostic methods and contact investigation. METHODS Retrospective comparative study of tuberculosis cases and incidence rates between both countries (1990-2010). Diagnostic methods and contact investigations were also evaluated for Mexico. Estimates were obtained from official websites....

Twin and family studies have shown that most traits are at least moderately heritable. But what are the implications of finding genetic influence for the design of intervention and prevention programs? For complex traits, heritability does not mean immutability, and research has shown that genetic influences can change with age, context, and in response to behavioral and drug interventions. The...

In this study, reactions of the simple cycloalkynes with substituted Nitrile Oxides, by DFT method will be discussed. The investigation of the structural properties, theoretical thermodynamic and kinetic data, i.e., the activation free energies(DG*), the free energies changes of reaction(DrG) and rate constants of the reactions (k) in 298 K and effects of Electron-withdrawing and...
