“…4), the activation energy of conduction is Ea  0.17 eV. The obtained value does not correspond to the depth of the band gap of the main energy levels for InSe [21] and best agrees with the activation energy of electrical conductivity in n-Mn2O3 thin films (Ea  0.11 eV) [20]. In n-Mn2O3/p-InSe heterojunctions, the n-Mn2O3 film makes the main contribution to the series resistance RS.…”

The conditions of application of thin semiconductor Mn2O3 films on p-InSe crystalline layered semiconductor substrates at a temperature of 623 K by the spray-pyrolysis method to create anisotypic heterojunctions n-Mn2O3/p-InSe were investigated. InSe is a promising material for photoelectronics. The use of the Mn2O3 film, which is transparent in the region of maximum photosensitivity of InSe, makes it possible to effectively exploit the optical properties of InSe in the fabrication of various semiconductor devices. The advantage of using layered semiconductors in the production of heterojunctions is that high-quality interfaces are obtained even with a significant discrepancy in the parameters of the crystal lattices of the starting materials. This significantly expands the choice of heterojunction materials. Electrical and photoelectric parameters of n-Mn2O3/p-InSe heterojunctions were measured and theoretical models describing them were proposed. The graphical dependencies of I-V characteristics, series resistance, height of the potential barrier and photosensitivity are constructed. It was established that these heterojunctions are photosensitive and have rectifying properties. Using the energy parameters of the starting materials, an energy diagram of the heterojunction was constructed, which allows for the analysis of physical processes in the obtained heterojunctions. Based on the temperature dependence of both direct and reverse I-V characteristics, the dynamics of changes in the energy parameters of the heterojunction with temperature, as well as the mechanisms of current flow through the heterojunction, are established. The spectral photosensitivity of the heterojunction was analyzed.

“…The peak positions of the prepared sample observed correspond to Mn2O3 When compared to the JCPDS standards (JCPDS card no: 01-089-0436), found to agree with the specified values with spherical lattice type.The characteristics, volume, and density are practically identical to their conventional values as can be shown. The calculated crystallite size is 32.86 nm, and XRD characteristics of the nano structures indicate that they are crystallographically oriented [27], as it was shown in figure 3. 3.1.2.…”

“…The Nanoparticles were washed and then heated in an oven to 65 °C for drying. The final step involved annealing the prepared materials for three hours at 500 °C [27]. With different characterization techniques, the nanoparticles were identified as manganese oxide nanoparticles on the nanoscale with a particle size of 32.86 nm and crystals with a size of 50-60 nanometers.…”

Manganese is essential for the synthesis of antioxidant enzymes and metabolic issues in Diabetes type 2 (DMT2), which is a worldwide disease, Chronic metabolic disorders cause insulin resistance, hyperglycemia, and complications like diabetic nephropathy. Arginase converts arginine to ornithine and urea. Increased arginase activity in DMT2 and diabetes nephropathy (DN)which has been linked to kidney damage, and arginase inhibitors can increase NO which is essential to vascular function. However, the molecular mechanisms of arginased is regulationare in DMT2 and DN are still unclear. This study examined the effect of manganese oxide nanoparticles (Mn2O3NPs) on arginase activity inhibition inserum samples from DMT2 and DN patients. We hypothesized that Mn2O3NPs alter cell redox status and signaling pathways, affecting DMT2 and DN arginase activity. We used a colorimetric assay to measure arginase activity in 80 serum samples from DMT2 and DN patients treated with different MnO2 NP concentrations to test our hypothesis. The current study characterized nanoparticles using various techniques such as IR, SEM, AFM, XRD, and EDX, which found it within nanoscale nature. Our findings are that Mn2O3NPs modulate arginase activity specificity in DM2 samples. SuggestionsMn2O3NPs could be used to develop new treatments for these conditions.
