Non-contact methods of SDO removal are considered in detail as a promising direction for creating safe and reliable space debris (SD) removal systems. The technical solution for removing the SDO from orbit must be selected taking into account the impact of the environment on the SDO and its motion parameters. The article is based on a detailed review and comparison of existing technical means for removing SDO from orbit. Solutions and approaches are analyzed that take into account the most important scientific research to determine the force effect on the SDO when using non-contact space debris removal systems. To remove SDO from low orbit, it is effective to use the force of aerodynamic drag. One of the means of non-contact removal of SDO from orbit using the atmosphere is inflatable braking devices (IBD), which provide a significant increase in the cross-sectional area. A promising method is non-contact method using an ion beam (IB) for applying force to SDO. The concept of such a device is considered, as well as the advantages and disadvantages of various transportation schemes using IB. The influence of space flight conditions on the movement of a space object during removal from orbit using non-contact methods is analyzed. The simulation results show that the proposed technical solutions can be used to remove space debris from low orbits. The research results make it possible to conduct a comparative analysis of various methods for removing space debris, indicating the scope of their application, main advantages and disadvantages.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"19 2","pages":"390 - 398"},"PeriodicalIF":0.4,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A promising material in terms of its fundamental properties is the inorganic halide perovskite CsPbBr3, whose electroluminescence brightness can reach 45 000 cd/m2. However, the most common thin-film technology for fabricating perovskite-based devices fails to address several key challenges, such as ensuring environmental stability of the perovskite, creating stretch-resistant contacts, and enabling efficient carrier injection into the electroluminescent layer. To address these issues, the authors developed a new device architecture based on a distributed electrode that incorporates an array of whisker nanocrystals embedded in the light-emitting layer, thereby solving the fundamental problem of the short carrier lifetime in CsPbBr3. The device is encapsulated in a special silicone polymer—a transparent, inert, flexible, and stretchable matrix that protects the CsPbBr3 perovskite from environmental exposure and preserves the orientation of the whisker nanocrystal arrays. Ninety-percent transparent single-walled carbon nanotubes, which possess high tensile strength and low electrical resistance, were used as the electrode responsible for lateral carrier transport. As a result, a flexible device with high electroluminescence efficiency was achieved.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"19 2","pages":"345 - 353"},"PeriodicalIF":0.4,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These two processes compete with each other during SPD. After a certain deformation, a steady-state concentration css of the second component is reached in the solution during SPD. This concentration can be found at the solvus line in the phase diagram at the certain temperature Teff (called usually effective temperature).

During prolonged orbital operation (10–20 years), the fluence of atomic oxygen reaches 1022 cm–2 and more; this leads to destruction of the polymer surface to a depth of several hundred micrometers. Three types of promising coatings based on organosilicon polymers are studied: the ECT-PC composition, ECT varnish, and UF-7-21 sealant, which are expected to be used on low-orbit spacecraft. To assess their resistance to atomic oxygen, when simulating an incident flow with a high fluence of up to 1022 cm–2 under laboratory conditions, a technique for accelerated tests in an oxygen plasma flow with an oxygen particle energy of 10–40 eV is applied. The dependences of mass loss on the equivalent fluence are studied; the measured erosion coefficients of the coatings of the ECT-PC composition, ECT varnish, and UF-7-21 sealant are found to be 4.2 × 10–26, 3.2 × 10–26, and 1.7 × 10–26 g/O atom, respectively. In comparison with polymers used in spacecraft (for example, polyimide with an erosion coefficient of 4.3 × 10–24 g/O atom), the measured erosion coefficients are two orders of magnitude lower, which characterizes the high resistance of the studied materials to atomic oxygen. On the basis of the obtained dependences of sample mass loss on plasma fluence, the predicted limiting fluence of atomic oxygen is (7–25) × 1023 cm–2 depending on the type and thickness of the coating.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"19 1","pages":"134 - 138"},"PeriodicalIF":0.4,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145144641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quantum motion of a particle in such a well is of interest in the context of quantum chaos phenomena. A previously developed numerical procedure for determining energy levels and wave functions of stationary states, which takes into account the symmetry of this problem, is applied to investigate the transverse motion of channeled positrons with energies of 5, 6, and 20 GeV. A classification of stationary states in transverse motion is proposed based on the theory of group representations. The wave functions of stationary states in an axially symmetric potential well are also determined, and the modification of these functions under the influence of a perturbation with equilateral triangle symmetry is demonstrated. In the upper region of the triangular potential well, classical motion is chaotic for the vast majority of initial conditions. The structure of the obtained wave functions in this region exhibits characteristic features predicted by the theory of quantum chaos.","PeriodicalId":671,"journal":{"name":"Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques","volume":"19 1","pages":"106 - 114"},"PeriodicalIF":0.4,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145144636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
