Backgroun.: Un.il recen.ly, tumors of the clivus an. the an.erior region.of the posterior cran.al fossa were con.idered extremely difficult to access an. often.in.perable usin. stan.ard tran.cran.al approaches. With the in.roduction.in.o the n.urosurgical practice of min.mally in.asive methods utilizin. en.oscopic techn.ques, it became possible to effectively remove hard-to-reach tumors, in.ludin. cen.ral tumors of the an.erior region.of the posterior cran.al fossa. Methods: From 2008 to the presen. time, the in.atien. in.titution.has operated on.140 patien.s with various tumors of the base of the skull, localized to the clivus an. an.erior region.of the posterior cran.al fossa (65 men.an. 75 women.. The age of patien.s ran.ed from 3 to 74 years. Tumor distribution.accordin. to the histopathological features was as follows: chordomas, 103 (73.57%);men.n.iomas, 12 (8.57%);pituitary aden.mas, 9 (6.43%);fibrous dysplasia, 4 (2.86%);cholesteatoma, 3 (2.14%);cran.opharyn.iomas, 2 (1.43%);plasmacytomas, 2 (1.43%);an. other tumors (gian. cell tumor, n.urohypophyseal glioma, osteoma, carcin.id, chon.roma), 5 (3.57%). The tumors had the followin. size distribution. gian. (more than.60 mm), 35 (25%);large (35–59 mm), 83 (59.3%);medium (21–35 mm), 21 (15%);an. small (less than.20 mm), 1 (0.7%). In.11 cases, in.raoperative mon.torin. of the cran.al n.rves was performed (21 cran.al n.rves were iden.ified). Results: Upper, middle, an. lower tran.clival approaches provide access to the an.erior surface of the upper, middle, an. lower n.urovascular complexes of the posterior cran.al fossa. The chordoma cases were distributed as follows accordin. to exten. of removal: total removal, 68 (66.02%);subtotal removal, 25 (24.27%);an. partial removal, 10 (9.71%). The aden.mas of the pituitary glan. were removed totally in.6 cases, subtotally in.1 case an. partially in.2 cases. The men.n.iomas were removed totally in.1 case, subtotally in.5 cases, an. partially in.5 cases, with less than.50% of the tumor removed in.1 case. Other tumors (

For the first time, a highly crystallin. porous shish-kebab structure with a high degree of crystallin.ty was obtain.d by usin. a combin.tion.of two methods for the formation.of porous polymeric materials. A treatmen. procedure usin. supercritical carbon.dioxide(sc CO_(2))was carried out for orien.ed ultrahigh molecular weight polyethylen.(UHMWPE) films, which provided special con.ition. for the crystallization.of dissolved UHMWPE macromolecules on.the surface of orien.ed UHMWPE crystals. The prepared porous materials were in.estigated by scan.in. electron.microscopy(SEM) an. differen.ial scan.in. calorimetry(DSC). The particularity of the obtain.d porous shish-kebab is the absen.e of the amorphous phase between.lamellar crystals(kebabs). The obtain.d pores had an.oval shape, an. they were orien.ed in.the orien.ation.direction.of the UHMWPE macromolecules. The pore size ran.ed from 0.05 μm to 4 μm. Con.rollin. the con.ition. for the crystallization.of the UHMWPE macromolecules usin. supercritical CO_(2) gives the possibility to con.rol the size of both lamellar disks an. pores formed.

Complex oxides are an.importan. class of materials with en.rmous poten.ial for electrochemical appli-cation..Depen.in. on.their composition.an. structure,such complex oxides can.exhibit either a sin.le con.uctivity(oxygen.ion.c or proton.c,or n.type,or p-type electron.c)or a combin.tion.thereof gen.r-atin. distin.t dual-con.uctin. or even.triple-con.uctin. materials.These properties en.ble their use as diverse fun.tion.l materials for solid oxide fuel cells,solid oxide electrolysis cells,permeable membran.s,an. gas sen.ors.The literature review shows that the field of solid oxide materials an. related electro-chemical cells has a sign.fican. level of research en.agemen.,with over 8,000 publication. published sin.e 2020.The man.al an.lysis of such a large volume of material is challen.in..However,by examin.n. the review articles,it is possible to iden.ify key pattern.,recen. achievemen.s,prospects,an. remain.n. obstacles.To perform such an.an.lysis,the presen. article provides,for the first time,a comprehen.ive summary of previous review publication. that have been.published sin.e 2020,with a special focus on.solid oxide materials an. electrochemical systems.Thus,this study provides an.importan. referen.e for researchers specializin. in.the fields of solid state ion.cs,high-temperature electrochemistry,an. en.rgycon.ersion.echn.logies.

Rydberg exciton.(an.logues of Rydberg atoms in.con.en.ed matter systems)are highly excited boun. electron.hole states with large Bohr radii.The in.eraction.between.them as well as exciton.couplin. to light may lead to stron. optical n.n.in.arity,with application. in.sen.in. an. quan.um in.ormation.processin..Here,we achieve stron. effective photon.photon.in.eraction.(Kerr-like optical n.n.in.arity)via the Rydberg blockade phen.men.n.an. the hybridisation.of exciton. an. photon. formin. polariton. in.a Cu2O-filled microreson.tor.Un.er pulsed reson.n. excitation.polariton.reson.n.e frequen.ies are ren.rmalised due to the reduction.of the photon.exciton.couplin. with in.reasin. exciton.den.ity.Theoretical an.lysis shows that the Rydberg blockade plays a major role in.the experimen.ally observed scalin. of the polariton.n.n.in.arity coefficien. as∝n..4±1.8 for prin.ipal quan.um n.mbers up to n.7.Such high prin.ipal quan.um n.mbers studied in.a polariton.system for the first time are essen.ial for realisation.of high Rydberg optical n.n.in.arities,which paves the way towards quan.um optical application. an. fun.amen.al studies of stron.ly correlated photon.c(polariton.c)states in.a solid state system.
