Phase diagram in the Bi-Pb-Sr-Ca-Cu-O system
Buffer effect of non-superconducting phases on oxygen exchange of the superconducting ones
TG-DTA and X-ray diffraction measurements at different temperatures and under different oxygen partial pressures were carried out on the species Bi1.6Pb0.4Sr2CuO6±x, Bi1.6Pb0.4Sr2CaCu2O8±y and Bi1.6Pb0.4Sr2Ca2Cu3O10±z to analyse the influence of the oxygen chemical potential on the phase transformations. A new phase was found at isobaric invariant equilibrium for 0.5≤
/PTot≤1 at 884°C. This new phase presents a buffer effect towards oxygen exchange between superconducting oxides and the gas phase.
al., 2017 ; Wingo, Ressler, & Bradley, 2014 ). This study, therefore, also tested whether the potential buffering effect of the two variables of character strength would also attenuate the relationship between psychological distress and IGD. To our
date, only one study has tested the moderating effect of psychological resilience in the relationships between psychological distress (depression/anxiety) and IGD, and no significant buffering effect was found in general Chinese adult populations ( Wu
on this model, this study longitudinally examined the (likely) individual risk contribution of anxiety between 16 and 18 years old, in relation to the potential buffering effect of classroom extraversion on this association
in the leukocyte count ( 37 ) because of an inflammatory response ( 1 ). The supplementation with antioxidants such as vitamin E (α-tocopherol) and its potential buffering effect against exercise-induced ROS have attracted the researchers
particular sources. Clearly, these two concepts overlap but are distinct ( Pierce, Sarason, & Sarason, 1991 ). The stress-buffering effect of social support may vary depending on the particular sources of support that college students perceived ( Lee
environments and allowed preservation of the calcareous eggshells. Such a buffering effect could have originated from the catchment bedrock and surficial sediments, the geology and composition of which are known to play an important role in determining local
