This study explores how the chemical interaction between magnesium hydride(mgH_(2))and the additive CrO_(3) influences the hydrogen/lithium storage characteristics of mgH_(2).We have observed that a 5 wt.%CrO_(3) additive reduces the dehydrogenation activation energy of mgH_(2) by 68 kJ/mol and lowers the required dehydrogenation temperature by 80℃.CrO_(3) added mgH_(2) was also tested as an anode in an Li ion battery,and it is possible to deliver over 90%of the total theoretical capacity(2038 mAh/g).Evidence for improved reversibility in the battery reaction is found only after the incorporation of additives with mgH_(2).In depth characterization study by X-ray diffraction(XRD)technique provides convincing evidence that the CrO_(3) additive interacts with mgH_(2) and produces Cr/mgO *** free energy analyses confirm the thermodynamic feasibility of conversion from mgH_(2)/CrO_(3) to mgO/Cr,which is well supported by the identification of Cr(0)in the powder by X ray photoelectron spectroscopy(XPS)*** high resolution transmission electron microscopy(HRTEm)and energy dispersive spectroscopy(EDS)we found evidence for the presence of 5 nm size Cr nanocrystals on the surface of mgO rock salt *** is also convincing ground to consider that mgO rock salt accommodates Cr in the *** observations support the argument that creation of active metal–metal dissolved rock salt oxide interface may be vital for improving the reactivity of mgH_(2),both for the improved storage of hydrogen and lithium.

Introduction: Treatments for cardiovascular diseases have increasingly evolved with the tendency to offer minimally invasive or transcatheter procedures instead of conventional sternotomy surgery. In this context, we highlight minimally invasive mitral valve surgery (mImVS), which has been shown to be an increasingly solid option with some superior results when compared to the conventional technique: better pain control, shorter hospital stays, shorter recovery time, shorter readmission rate in the first postoperative year, better aesthetic results, and lower overall cost. Aim: This study aims to evaluate the stages of mImVS, by primary mitral valve consultation, in our service and compare these results with data from the literature. methods: All electronic medical records of patients who underwent mImVS for primary mitral valve injury in the Encore Hospital from January 2020 to february 2023 were analyzed. Tabulation and statistical analysis were performed using the microsoft Excel® program. Quantitative variables were presented as means, standard deviations. Results: 46 patients were enrolled in our study (Age: 59.1 ± 12.4 years old;60.8% female, BmI: 26 ± 4.4 Kg/m2, Low risk STS score: 82.6%). The observed 30-day mortality was 2.1%, plastic rate of 23.9%, blood transfusion rate of 41.3%, length of stay in an intensive care bed (ICB) of 3.3 ± 3.3 days and hospital stay of 6.4 ± 5.1 days. Conclusions: We noticed that the mImVS results carried out in our service agree with data from national and international literature with approximately 1.3 days more hospitalization in ICB.
