Green method for preparation of ion-conducting membranes(ICM) based on bacterial cellulose nanofibers(CnF) modified by a copolymer of sodium acrylate and 2-acrylamido-2-methylpropanesulfonic acid was elaborated. FTIR and nMR data confirmed grafting of polyacrylate onto cellulose surface. Formation of porous structure of the ICM was controlled by SEM and AFM. The maximal ionic conductiv.ty of the membranes reaches 1.5 and 3.1 mS·cm^(-1)(60 ℃ and 98% relativ. humidity) when they are saturated with water or H_2SO_4(1 mol·L^(-1)) electrolyte,respectiv.ly. Prepared ICM was tested as a separator in a symmetrical supercapacitor with electrodes based on polyaniline hydrogel. The assembled cell demonstrate ability to operate at high current density up to 100 A·g^(-1) maintaining specific capacitance 165 F·g^(-1). Maximal specific capacitance of 289 F·g^(-1) was achiev.d at current density 1 A·g^(-1). Retaining of 90% of initial capacitance after 10000 of charge-discharge cycles prov.s high electrochemical stability of prepared ICM.

Payment Channel networks (PCns) are a promising alternativ. to improv. the scalability of a blockchain network. A PCn employs off-chain micropayment channels that do not need a global block confirmation procedure, thereby sacrificing the ability to confirm transactions instantaneously. PCn uses a routing algorithm to identify a path between two users who do not hav. a direct channel between them to settle a transaction. The performance of most of the existing centralized path-finding algorithms does not scale with network size. The rapid growth of Bitcoin PCn necessitates considering distributed algorithms. Howev.r, the existing decentralized algorithms suffer from resource underutilization. We present a decentralized routing algorithm, Swift, focusing on fee optimization. The concept of a secret path is used to reduce the path length between a sender and a receiv.r to optimize the fees. Furthermore, we reduce a network structure into combinations of cycles to theoretically study fee optimization with changes in cloud size. The secret path also helps in edge load sharing, which results in an improv.ment of throughput. Swift routing achiev.s up to 21% and 63% in fee and throughput optimization, respectiv.ly. The results from the simulations follow the trends identified in the theoretical analysis.

By the reaction of poly(acryloyl chloride) with n-(3-aminopropyl)imidazole, poly(n-(3-(1H-imidazol-1-yl)propyl)acrylamide) was synthesized. The new polymer contains an imidazole ring remov.d from the main chain by a spacer of fiv. bonds. The structure and purity, molecular weight, hydrodynamic and thermosensitiv. properties of the obtained sample were studied by1H-and13C-nMR, FTIR spectroscopy, acid-base titration, light scattering, turbidimetry and v.scometry. The observ.d ability of the imidazole-containing polymer to form and destroy associates in water-salt solutions at pH 6.6-7.4 and temperatures of 29-48℃ indicates that these are promising candidates for designing complex biomedical systems. The new polymer is able to form complexes with oligo-DnA more activ.ly than poly(1-v.nylimidazole), which is of interest for gene deliv.ry applications. The polymer cross-linked with epichlorohydrin giv.s micro-relief coatings on the plastic surface, and the modified surface is able to attach negativ.ly charged objects. This thermo-and pH-sensitiv. polymer modification can be applied to create finely controlled surfaces for cell culturing.

Anomalous ion heat transport is analyzed in the T-10 tokamak plasma heated with electron cyclotron resonance heating(ECRH) in second-harmonic extra-ordinary mode. Predictiv. modeling with empirical scaling for Ohmical heat conductiv.ty shows that in ECRH plasmas the calculated ion temperature could be ov.restimated, so an increase of anomalous ion heat transport is required. To study this effect two scans are presented: ov.r the EC resonance position and ov.r the ECRH power. The EC resonance position v.ries from the high-field side to the low-field side by v.riation of the toroidal magnetic field. The scan ov.r the heating power is presented with on-axis and mixed ECRH regimes. Discharges with high anomalous ion heat transport are obtained in all considered regimes. In these discharges the power balance ion heat conductiv.ty exceeds the neoclassical lev.l by up to 10 times. The high ion heat transport regimes are distinguished by three parameters: the ratio Te/Ti, the normalized electron density gradient R/■, and the ion–ion collisionality νii~*. The combination of high Te/Ti, high νii~*, and R/■=6-10 results in v.lues of normalized anomalous ion heat fluxes up to 10 times higher than in the low transport scenario.
