“…13. This is based upon the samples tested in this study and in previous studies [7,11], which are summarized in Table 4. The color coding in the table indicates experimentally observed susceptibility of elements (purple), sulfide (pink), and sulfate (olive green) formation, as well as elements (in green) that do not react in the Venus environment, relative to the Venus atmospheric constituent elements (blue).…”

“…In an oxidation process, it is often desirable that a stable, dense, and protective oxide scale forms so as to limit further material reactions at the surface as well as chemical reactions propagating further into the structure. Although it is not understood in terms of the Venus surface atmosphere, the carbon released in previously studied SC CO 2 reactions has promoted formation of a porous oxide for some metals, which provides the ideal conditions for further diffusion of molecular and ionic species, thereby enabling further reactions between the SC and solid phases [11]. The extent of corrosion in steels was also found to be dependent on the role of the alloying elements present [aluminum (Al), molybdenum (Mo), chromium (Cr), and Ni] in mitigating some of the effects of the SC CO 2 [8].…”

Materials used in the fabrication of landers for Venus exploration need to be carefully selected to assure functional durability throughout anticipated prolonged future mission durations in the harsh conditions that include 460°C and 9.2 MPa pressure with supercritical CO 2 and trace corrosive gases. Previous work has shown the adverse effects that trace quantities of the atmospheric sulfide and halogen Venus gas constituents have on some materials used in sensor and electronic component fabrication. In this study, a limited, systematic evaluation of several pure elemental metals as well as Ti-6Al-4 V is conducted to determine on an elemental level the constituents of structural materials that could survive prolonged Venus exploration. The metals are characterized before and after exposure to a simulated Venus surface atmosphere using X-ray photoelectron spectroscopy, Auger electron spectroscopy, energy-dispersive spectroscopy, and field-emission-scanning electron microscopy. Ti-6Al-4 V, titanium, and molybdenum all demonstrate stability when exposed to the simulated Venus surface environment. In contrast, cobalt, palladium, and to some extent chromium have adverse reactions to the sulfur constituents. The 96% supercritical CO 2 leads to the complete oxidation of niobium and zirconium, as well as spalling oxide layers on tantalum and formation of a thick oxide layer on tungsten.xM yCOg MxOy yC s R1xM yCO 2 g MxOy yCOg R22COg CO 2 g C s Boudouard reaction

“…150kGy and 250 kGy and remarkably increases for 75 kGy. This can be attributed in a way that chromium occupies at the same position as iron in the octahedral sites of the crystalline structure of magnetite and that its formula can be represented as Fe 3-x Cr x O 4 [26] . This peak can be attributed to FeCr 2 O 4 [27].…”

Influence of Cu on the Performance of Tuberose Architecture of Strontium Hydroxide Thin Film as a Supercapacitor Electrode

A simple, economical successive ionic layer adsorption and reaction (SILAR) method has been used for synthesizing 1, 2 and 3 at.% copper‐doped strontium hydroxide over a stainless‐steel (SS) substrate. X‐ray diffraction reveals the orthorhombic crystal structure of polycrystalline Cu‐doped Sr(OH)2. FTIR and Raman analyses explore the chemical bond analysis of the active material. The morphology of the Cu‐doped Sr(OH)2 was analyzed by using SEM. This shows novel hierarchical‐branched tuberose with flakes. The energy‐dispersive X‐ray spectroscopy (EDAX) also confirms the doping of Cu into Sr(OH)2. The electrochemical properties have been investigated by using cyclic voltammetry (CV) and galvanostatic charge−discharge measurements. It has been perceived that doping clearly affects the supercapacitive behavior. The specific capacity of the 3 at.% Cu‐doped Sr(OH)2 film electrode exhibits a maximum specific capacity of 817 C g−1 at 0.4 mA cm−1 in 1 M Na2SO4 electrolyte, but has a low cycle stability. The 2 at.% Cu‐doped sample shows high cycle stability by retrieving 71 % of its capacity after 5000 cycles. The relationship between the doping concentration and supercapacitive behavior has also been discussed. The good capacitive behavior and cycle stability of the Cu‐doped Sr(OH)2 gives the new perspective for the flexible electrode material, which can be used in the near future as an energy storage material.
