THERMODYNAMIC PROPERTIES OF THE Sb2Te3 COMPOUND

Thermodynamic properties of the Sb2Te3 compound were studied by measuring electromotive force (EMF) with a liquid electrolyte in the temperature range of 300-450 K. The partial molar functions of antimony in alloys and the corresponding standard integral thermodynamic functions of the Sb2Te3 compound were calculated for the first time based on the EMF measurements under standard conditions. Comparative analysis of obtained results with literature data was carried out

Thermodynamic properties of the GdTe3 compound

The alloys of the Gd-Te system in the range of compositions > 75 at% Te were studied by the methods of X-ray diffraction (XRD) and electromotive forces (EMF). From the EMF measurements of the concentration cells relative to the GdTe electrode in the 300-450 K temperature range, the partial thermodynamic functions of GdTe in alloys were determined. By combining these data with the corresponding functions of Gd in GdTe, the partial molar functions of gadolinium in GdTe3+Te alloys, and standard thermodynamic functions of formation and standard entropy of the GdTe3 compound were calculated. The obtained results were compared with the literature data.

Thermodynamic study of manganese tellurides by the electromotive force method

The thermodynamic properties of manganese tellurides were determined using an electromotive force (EMF) method with a liquid electrolyte in a temperature range from 300 to 450 K. EMF measurements were performed using equilibrium samples taken from the two-phase regions, namely MnTe2 + Te and MnTe + MnTe2, of the Mn–Te system. The phase compositions of all samples were controlled with the X-ray diffraction (XRD) method. The partial molar functions of manganese in alloys, as well as the standard thermodynamic functions of the formation and standard entropies of MnTe and MnTe2, were calculated. A comparative analysis of obtained results with literature data is performed

Thermodynamic study of a synthetic analog of the famatinite mineral - Cu3SbS4

Fundamental thermodynamic properties of the synthetic analog of the famatinite mineral - Cu3SbS4 were studied on the basis of electromotive force (EMF) measurements. The EMF of the concentration chains relative to the Cu electrode with a solid electrolyte was measured for the alloys from the Cu3SbS4 + Sb2S3 + S phase region at 300-380K temperature interval. Based on measurement data, the relative partial thermodynamic functions of copper in alloys, the standard thermodynamic functions of formation, as well as, the standard entropy of the Cu3SbS4 ternary compound were calculated for the first time.

Anomalous Magnetic Field Cancer Cause And Therapeutic Possibilities By Natural Earth Magnetic Field

Cancer cause are three factors, stated by official medical science: cancerogenous substances, viruses and physical agencies from external environment. Earth magnetic fields (EMF) measurements have started in cancer diseased patients' rooms. The measured high magnetic fields intensities found much higher than EMF, are named anomalous magnetic fields (AMF). Work Aim: Prove that AMF enabled body viscous magnetization (BVM) formation. Explain that BVM in breast creates breast cancer. Prove that locating breast cancer patients away from AMF to natural EMF leads to recovery. Explain that today's medical science risk factors are misinterpreted. Show that mammography and scintigraphy are evidence that AMF created breast cancer. Work Method: AMF measurements were performed with a protonic magnetometer. Three patients groups were included in AMF measurements. Physiology and etiopathological literature were studied. Results: AMF measurements in breast cancer patients' beds if found BVM was formed, enabling paraoncogen into oncogene mutation, and then clonal breast cancer developed. Thousands examples were measured and there were no breast cancer disease created in natural EMF. Based on a 6 patients group with metastases, it can be said that time limits for starting the disease treatment are not taken into account, but everything should be treated, including palliative patients, but in natural EMF. Conclusion: It was found that environmental AMF created BVM producing breast cancer. It is proven that locating patients away from AMF to a natural EMF leads to recovery. It is proven that the official risk factors are AMF consequences and not breast cancer causes. In advanced diseases with metastases where surgery cannot remove everything, it is necessary to introduce hyperthermia - only in natural EMF.

Thermodynamic Stability and Microscopic Behavior of BaxSr1-xCo1-yFeyO3-δ Perovskites

The mixed conducting perovskite-type oxides BaxSr1-xCo1-yFeyO3-δ (BSCF) are intensively studied as potential high-performance solid oxide fuel cell cathode materials. The effect of different compositional variables and oxygen stoichiometry on the structure and thermodynamic stability of the BaxSr1-xCo1-yFeyO3-δ (x = 0.2, 0.4, 0.5, 0.6, 0.8; y = 0.2, 0.4, 0.6, 0.8, 1) perovskite-type compositions were investigated by solid electrolyte electrochemical cells method and scanning electron microscopy (SEM). The thermodynamic quantities represented by the partial molar free energies, enthalpies and entropies of oxygen dissolution in the perovskite phase, as well as the equilibrium partial pressures of oxygen were obtained in the temperature range of 823–1273 K. The in situ change of oxygen stoichiometry and the determination of thermodynamic parameters of the new oxygen-deficient BSCF compositions were studied via coulometric titration technique coupled with electromotive force (EMF) measurements. The effect of A- and B-site dopants concentration correlated to the variation of oxygen stoichiometry on the thermodynamic stability and morphology of the BSCF samples was evidenced.
