    No full text
    Lifecycle management of high-tech products plays an important role in ensuring the effective operation of all entities involved in its production. The peculiarity of life cycle management lies in the intensification, reduction of the production cycle, it is this aspect that is key in high-tech industries. The proposed work formulates the main stages of modeling digital twins of onboard equipment, the concept of the structure of the life cycle of onboard equipment of rocket and space products, built using digital twins.</jats:p

    Platelike LiMPO<sub>4</sub> (M = Fe, Mn, Co, Ni) for Possible Application in Rechargeable Li Ion Batteries: Beyond Nanosize

    The peculiarities of LiMPO4 (M = Fe, Mn, Co, Ni) formation with controlled platelike crystal shape using layered M(OH)2 hydroxides as templates were studied. Thin, platelike crystals of NH4MPO4·H2O with Mn, Fe, and Co were formed in aqueous solutions as intermediate products, whereas for NH4NiPO4·6H2O, particles in the form of spherulites were observed. For replacement of ammonium groups by lithium cations, a solid-state reaction between NH4MPO4·xH2O and Li2CO3 at elevated temperatures was used. The obtained LiMPO4 particles repeat completely the shape of the intermediated NH4MPO4·xH2O crystals. The surface of platelike particles represents a cellular structure and consists of agglomerated, slightly randomized crystallites of several hundred nanometers, which are oriented along the c-axis perpendicular to the plate surface. It was shown in the LiFePO4 example that the cathode materials, consisting of platelike particles and reduced graphene oxide (RGO), have the discharge capacity of 145 mAh/g in Li ion batteries after 10 cycles with 0.1C. This value can successfully compete with the best literature results reported for nanosized LiFePO4/RGO cathode materials. A possible explanation of that is discussed

    Information and Legal Resources in Social Work: New Technological Challenges

    No full text
    The article examines information resources and legal support in social work, taking into account changes in the parameters of interaction between social services and recipients of social services. Digitalization in the field of social services is causing changes in the forms of interaction between subjects and between subjects and information. In this regard, the issues of the regulatory framework are being rethought again. With the advent of a new methodology for achieving the parameters of the “knowledge society”, the effectiveness of social services for the population is increasing. At the same time, there is a risk of potential threats to human rights, information security, and the preservation of the model of humanism as the basis for constructing practices in the social sphere. Timely legal decisions and civic engagement will help not only to provide an adequate response to new challenges, but will also contribute to the deep modernization of the social sphere.</jats:p
