In th.s article, th. analysis of Tsallis h.lograph.c dark energy(wh.ch.turns into h.lograph.c dark energy for a particular ch.ice of positiv. non-additiv.ty parameter δ) in modified f(T, B) grav.ty with.th. v.lidity of th.rmodynamics and energy conditions for a h.mogeneous and isotropic FLRW Univ.rse h.s been studied. Th. enligh.enment of th. field equation towards f(T,B)=αT^m+βB^n, made possible by th. fact th.t th. model is purely accelerating,corresponds to q=-0.54(Mamon and Das 2017 Eur. Ph.s.J.C 77 49). Th. generalized second law of th.rmodynamics is v.lid not only for th. same temperature inside th. h.rizon, but also for th. apparent h.rizon for a ch.nge in temperature. Th. essential inspiration driv.ng th.s article is to exh.bit th. applicability th.t th. h.lograph.c dark energy ach.ev.d from standard Tsallis h.lograph.c dark energy and th. components acquired from f(T, B) grav.ty are identical for th. specific bounty of constants.

In model experiments were studied th. effect of cosmo-geoph.sical factors of env.ronment (h.pomagnetic conditions dur.ng 2 days ≈ 1 mkT;electromagnetic irradiation (10 min - 2 Mh. with.amplitude 5 v.m and power 30 mkv., background 2 - 4 mkv.), γ-quantum (10 min—from th. source 137Cs) and its combined effect on th. ph.sic-ch.mical properties (ORP and ph. of growing medium for cell culture of mammals as nutrition medium 199 (PanEco, Russia). It was used a clear solution of medium (solution 1) and with.th. adding of 10% embryo bull serum—model of bio-medium (solution 2). h.pomagnetic conditions ev.ked th. decreasing of ORP and ph.v.lue in both.solutions, electromagnetic irradiation in th. solution 1 wh.ch.ev.ked th. decreasing of ORP and th. increasing of ph.v.lue, and in th. solution 2, on th. contrary, th. increasing of ORP with.th. unch.nging ph.v.lue. γ-radiation sh.rply decreased ORP v.lue and didn’t ch.nge ph.in solution 1, i.e. th. reduction properties increased. Th.re is insignificant increasing of ORP v.lue and th. decreasing of ph.is noted in th. solution 2, th.t it is ch.racterized with.th. increasing of oxidativ. properties of solution. Under th. combined effect of h.pomagnetic conditions and electromagnetic irradiation, th. v.lues of inv.stigating parameters in th. solution 1 decreased and in th. solution 2 increased. It was observ.d acute decreasing of ORP v.lue in both.solutions under th. combined effect of h.pomagnetic conditions and γ-radiation, i.e. th. reductiv. properties of th. solutions increased sh.rply. In th.s th. concentration h. significantly decreased, (p γ-radiation led to th. decreasing of ORP and ph.v.lues in both.solutions. Th.s, th. studying factors significantly ch.nge th. oxidation-reduction properties of growing mediums.

Green meth.d for preparation of ion-conducting membranes(ICM) based on bacterial cellulose nanofibers(CnF) modified by a copolymer of sodium acrylate and 2-acrylamido-2-meth.lpropanesulfonic acid was elaborated. FTIR and nMR data confirmed grafting of polyacrylate onto cellulose surface. Formation of porous structure of th. ICM was controlled by SEM and AFM. Th. maximal ionic conductiv.ty of th. membranes reach.s 1.5 and 3.1 mS·cm^(-1)(60 ℃ and 98% relativ. h.midity) wh.n th.y 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 h.drogel. Th. assembled cell demonstrate ability to operate at h.gh.current density up to 100 A·g^(-1) maintaining specific capacitance 165 F·g^(-1). Maximal specific capacitance of 289 F·g^(-1) was ach.ev.d at current density 1 A·g^(-1). Retaining of 90% of initial capacitance after 10000 of ch.rge-disch.rge cycles prov.s h.gh.electroch.mical stability of prepared ICM.
