Recently, dielectric materials with high energy storage capacity, low loss, and good temperature stability are highly desired for the rapidly growing field of power electronics. In the current work, we have investigated the change in electrical, optical, and dielectric properties by varying the concentration of compositional elements Sn and Mn. We have prepared the Sn1–x Mn x S (0.1, 0.3, 0.5, 0.7, and 0.9) matrix by using the simple single-step hydrothermal method. The samples show that the reflectance percentage increased with the increase of the Mn amount in the composition. The samples exhibit narrow band gap values, which further increase with the Mn content. The band gap value increases from 0.43 to 0.56 eV. The structural analysis shows that the prepared samples are polycrystalline in nature, having SnS and MnS phases. Furthermore, the crystallite sizes increase with an increase in Mn addition, whereas dislocation density and strain decrease simultaneously. The refractive index is calculated from optical band gap values by using the Dimitrov and Sakka equation. The morphological study reveals the uniformity in size and shape of the prepared composition throughout the sample. The presence of compositional elements Sn, Mn, and S is confirmed by EDX analysis. The electrical study reveals that the sample shows good electrical properties, which increase with the Mn contents. The dielectric behavior as a function of frequency and temperature was investigated, and the parameters like dielectric constant, AC conductivity, impedance spectroscopy, and electric modulus were deeply analyzed. All the above optical, electrical, and dielectric properties of the SnMnS matrix have potential use in the field of electronic and energy storage device applications.

Brackets are the load-bearing components in a satellite. The current age of satellites comprises specific brackets that set out as a link between the bodies of the satellite, reflector parts, and feeder facilities mounted at its upper end. Brackets are used to carry loads of the satellite body frame, supporting elements, batteries, and electronic goods. The article explicates the various brackets used in satellites and aircrafts. The strength of the bracket is of utmost importance since it is an important load supporting member in several assemblies of aircraft and satellites. In addition to the mechanical strength, the weight of the bracket is a major concern as it adds to the total weight of the aircraft and satellite. Thus, weight savings of brackets can be of paramount importance and Additive Manufacturing (AM) is found as an overall solution to achieve the same. Hence, in addition to various brackets used in satellites, the article presents an exhaustive review of the processing of various advanced functional materials using various AM techniques to make high strength-to-weight ratio satellite brackets. The use of DFAM by various satellite manufacturers globally for optimizing the structure of the brackets resulting in a significant weight saving of the brackets is also presented in the article.

Here, we have reported an excellent optical, dielectric, and electrical behavior of Cu 2 Ni 1+x Sn 1−x S 4 (CNTS) nanospheres synthesized by the facile solvothermal technique. From its structural analysis, the polycrystalline nature of the material was confirmed due to the presence of the sphalerite phase along with several secondary phases, demonstrating the structural tuning possibilities with a compositional variation. Further analysis of the electronic structure showed the presence of Cu +1 , Ni +2 , Sn +4 , and S −2 valence states in the composition. The nanoflower-like morphology made up of nanospheres remained the same even after the compositional variation and enhanced the light-trapping effect. However, the increase in the optical band gap and decrease in the refractive index showed distinctive properties with the Ni concentration variation. The frequency and temperature-dependent behavior of dielectric parameters, conductivity, impedance, and electric modulus parameters broadened the application possibilities along with the optoelectronic properties. The increase in AC conductivity with temperature enabled the hopping of charge carriers, and properties like an increase in the loss factor at a lower frequency and higher temperature made the nanomaterials favorable for devices based on high-power circuits. The decrease in impedance values indicated less current dissipation in lower-frequency regions, and the electric modulus parameter showed non-Debye-type behavior. The tunable optical, dielectric, and electrical properties of the CNTS materials widen the cutting-edge optoelectronic application possibilities.
