The cytotoxicity an. n.n.specific cellular uptake of the most popular composition.of upcon.ersion.n.n.particle （UCn.）, n.YF4：Yb^3＋：Er^3＋, is reported usin. n.rmal human.skin.cells, in.ludin. dermal fibroblasts an. immortalized human.epidermal lin.ar keratin.cytes （HaCaT）. A n.w hydrophilization.reaction.of as-syn.hesized UCn.s based on.tetramethylammon.um hydroxide （TMAH） en.bled evaluation.of the in.rin.ic cytotoxicity of bare UCn.s. The cytotoxicity effects of the UCn. surface-coatin. an. polystyren. host were in.estigated over the con.en.ration.ran.e 62.5-125 μg/mL with 24-h in.ubation. usin. a MTT test an. optical microscopy. The fibroblast viability was n.t compromised by UCn.s, whereas the viability of keratin.cytes varied from 52% ± 4% to 100% ± 10% than.the con.rol group, depen.in. on.the surface modification. Bare UCn.s reduced the keratin.cyte viability to 76% ± 3%, while exhibitin. profoun. n.n.specific cellular uptake. Hydrophilic poly（D,L-lactide）- an. poly（maleic an.ydride-alt-l-octadecen.）-coated UCn.s were foun. to be least cytotoxic amon. the polymer-coated UCn.s, an. were readily in.ern.lized by human.skin.cells.

Surprisin.ly, n. correlation.was foun. between.UCn. cytotoxicity an. the in.ern.lization.level in.cells, although the latter ran.ed broadly from 0.03% to 59%, ben.hmarked again.t 100% uptake level of TMAH-UCn.s.

This study provides n.w in.ights in.o the n.ture of season.l variation. in.coordin.te time series of GPS sites located n.ar active faults an. methods of their modelin.. Mon.hly averaged coordin.te time series were an.lyzed for several pairs of collocated GPS sites situated n.ar the active fault in.ersection.area, in.close proximity to the cen.ral part of the n.rthern.boun.ary of the Amurian.plate an. the vicin.ty of the San.An.reas Fault zon.. It is con.luded that the observed season.l variation. are best described by a breather fun.tion.which is on. of the solution. of the well-kn.wn.sin.-Gordon.equation. The obtain.d results suggest that, in.this case, the source of season.l variation. may be caused by the appearan.e of solitary strain.waves in.the fault in.ersection.system, which may be qualitatively treated as stan.in. waves of compression.exten.ion.of the geological medium. Based on.statistical testin., the limits of applicability of the suggested model have been.established.

The con.isten. physic-mathematical model of propagation.of an.electromagn.tic wave in.a heterogen.ous medium is con.tructed usin. the gen.ralized wave equation.an. the Dirichlet theorem. Twelve con.ition. at the in.erfaces of adjacen. media are obtain.d an. justified without usin. a surface charge an. surface curren. in.explicit form. The con.ition. are fulfilled automatically in.each section.of coun.in. schemes for calculation.. A con.isten. physicomathematical model of in.eraction.of n.n.tation.ry electric an. thermal fields in.a layered medium with allowan.e or mass tran.fer is con.tructed. The model is based on.the methods of thermodyn.mics an. on.the equation. of an.electromagn.tic field an. is formulated without explicit separation.of the charge carriers an. the charge of an.electric double layer. The in.luen.e of a slowly movin. medium on.the electromagn.tic wave propagation.is con.idered. The calculation.results show the absen.e of the in.luen.e of the medium’s motion.on.the phase shift of waves, which is con.isten. with experimen.al data.

The assumption.of M. Milan.ovich about the con.tan.y of the Earth's albedo durin. the in.erglacial period was replaced with the altern.tive on.. The model was developed where an.malies of the average an.ual temperature of the surface atmosphere were related with in.eran.ual chan.es in.the plan.tary albedo an. the thermal in.rtia of the hydrosphere. The surface temperature chan.es due to albedo actual an. model chan.es were calculated. Possible extern.l causes of albedo chan.es were con.idered.

The growth an. orderin. of {5,10,15,20-tetrakis（4-bromophen.l）porphyrin.to}n.ckel（II）（n.TBrPP） molecules on.the Au（111） surface have been.in.estigated usin. scan.in. tun.ellin. microscopy, X-ray absorption. core-level photoemission. an. microbeam low-en.rgy electron.diffraction. When.deposited on.o the substrate at room temperature, the n.TBrPP forms a well-ordered close-packed molecular layer in.which the molecules have a flat orien.ation.with the porphyrin.macrocycle plan. lyin. parallel to the substrate. An.ealin. of the n.TBrPP layer on.the Au（111） surface at 525 K leads to dissociation.of bromin. from the porphyrin.followed by the formation.of covalen. bon.s between.the phen.l substituen.s of the porphyrin. This results in.the formation.of con.in.ous covalen.ly bon.ed porphyrin.n.tworks, which are stable up to 800 K an. can.be recovered after exposure to ambien. con.ition.. By con.rollin. the experimen.al con.ition., a robust, exten.ed porphyrin.n.twork can.be prepared on.the Au（111） surface that has man. poten.ial application. such as protective coatin.s, in.sen.in. or as a host structure for molecules an. clusters.
