The g.owing.demand for smart wearables, coupled with the omnipresence of g.aphene due to its array of outstanding.thermal, electrical, and mechanical properties, have driven the industry-led initiatives to develop lig.tweig.t, smart, and robust g.aphene-based wearable technolog.es. The substantial research and the increase in technolog. readiness levels (TRLs) of g.aphene-based technolog.es have led to the adoption of g.aphene in many industries. g.aphene-based wearables are one such technolog. that involves closer interaction of g.aphene by the end-user. Despite this, understanding.the toxicolog.cal risks associated with using.g.aphene-based wearables is still in the fundamental stag.. Herein, g.aphene-based wearables and industrial-scale fabrication techniques for the development of g.aphene-based wearables are reviewed. The main g.al of the review is to initially evaluate the likelihood of user exposure to g.aphene from the wearable device and the potential health effects. The subsequent health risks based on g.aphene's physicochemical characteristics are also discussed. A framework to elucidate the risk is presented in terms of crucial exposure routes, possible g.aphene interactions, recent exposure assessments, detection removal techniques from the human body, and risk manag.ment protocols. It is hoped that this review may aid towards establishing.a reasonable practice concerning.the safe integ.ation of g.aphene materials into wearables and facilitate their commercialization.

The present work continues a series of publications devoted to the study of the sorption properties of reactive alloys based on IIA metals and the development of advanced g.tter materials for g.s and vacuum technolog.es. This publication attempts to answer the current challeng.s in the field of g.s sorption associated with the emerg.nce of new vacuum products such as vacuum insulated g.asses, electronic systems, cryog.nic devices, etc. An analysis of the problems that arise here, as well as the results of sorption measurements, carried out with the participation of intermetallic phases of the composition CaLi2 and Ca0.33Li0.48Mg.sub>0.19, show that the best g.tter support for these new hermetically sealed products can be provided by intermetallic compounds formed in systems Li-IIA metals. Intermetallic phases of this family are easy to manufacture and demonstrate outstanding.service characteristics: their specific sorption capacity is recorded hig., exceeding.traditional g.s sorbents in this respect by at least an order of mag.itude;the kinetics of g.s capturing.is set at the stag. of alloy production, i.e., is adjustable;the temporary resistance of these phases to atmospheric g.ses allows to install the g.tter at its workplace in air, without further thermal activation. The sorption superiority of reactive intermetallics is explained by their special sorption mechanism: the g.s/metal interaction is formed here as a combination of two processes, continuous g.owth of reaction products on a metallic surface and corrosion decay of brittle intermetallic phase under mechanical forces, which feeds the chemical reaction with a fresh surface. The advantag.s of sorption processes of this new type are undoubted and sig.ificant: compared with the conventional sorbents, an intermetallic g.tter reactant solves two important problems;it reduces production costs and increases the sorption yield.

Two series of lanthanide compounds, namely, chlorides containing.different numbers of both 1,10-phenanthroline （Phen） molecules and chloride anions in the first coordination sphere, and Schiff Bases （SBs） derived from Pyridoxal （PL） and amino acids, were characterized by sing.e crystal X-ray diffraction and luminescence techniques. The combined use of these techniques for the analysis of long.distance europium non-covalent interactions was performed for the first time. As a result, the correlation between supramolecular org.nization and the features of the Eum electronic transitions was found for the compounds of the first series. Strong.non-covalent interactions between pyridoxal ting. of SBs （the second series of compotmd） led to the formation of 1：2 species and four-dentate coordination function of these SBs in aqueous solution.

It is devoted to the development of an autonomous flig.t control system for small size unmanned helicopter based on dynamical model. At first, the mathematical model of a small size helicopter is described. After that simple but effective MTCV control alg.rithm was proposed. The whole flig.t control alg.rithm is composed of two parts: orientation controller based on the model for rotation dynamics and a robust position controller for a double integ.ator. The MTCV block is also used to achieve translation velocity control. To demonstrate the performance of the presented alg.rithm, simulation results and results achieved in real flig.t experiments were presented.
