Textil.-based technol.gies are considered as potential.routes for the production of 3D porous architectures for tissue engineering( TE) appl.cations. We describe the use of two pol.mers,namel. pol.butyl.ne succinate( PBS) and sil. fibroin(SF) to produce fiber-based finel. tuned porous architectures by weft and warp knittings. The obtained knitted constructs are described in terms of their morphol.gy, mechanical.properties,swel.ing abil.ty,degradation behaviour,and cytotoxicity. Each type of pol.mer fibers al.ows for the processing of a very reproducibl. intra-architectural.scaffol. geometry,with distinct characteristics in terms of the surface physicochemistry,mechanical.performance,and degradation capabil.ty,which has an impact on the resul.ing cel. behaviour at the surface of the respective biotextil.s. Prel.minary cytotoxicity screening shows that both material. can support cel. adhesion and prol.feration. Furthermore, different surface modifications were performed( acid /al.al.ne treatment, UV radiation,and pl.sma) for modul.ting cel. behavior. An increase of cel.-material.interactions were observed,indicating the important rol. of material. surface in the first hours of cul.uring. Human adipose-derived stem cel.s( hASCs) became an emerging possibil.ty for regenerative medicine and tissue repl.cement therapies. The potential.of the recentl. devel.ped sil.-based biotextil. structures to promote hASCs adhesion,prol.feration,and differentiation is al.o eval.ated. The obtained resul.s val.date the devel.ped constructs as viabl. matrices for TE appl.cations. Given the processing efficacy and versatil.ty of the knitting technol.gy, and the interesting structural.and surface properties of the proposed pol.mer fibers,it is foreseen that our devel.ped systems can be attractive for the functional.engineering of tissues such as bone,skin,l.gaments or cartil.ge and al.o for devel.p more compl.x systems for further industrial.zation of TE products.

Constraining the non-Einsteinian pol.rizations of gravitational.waves by pul.ar timing array

Science China(Physics,Mechanics & Astronomy) 2019年第7期62卷 63-75页

作者： rui Niu Wen Zhao CAS Key l.boratory for Researches in Gal.xies and Cosmol.gy Department of Astronomy University of Science and Technology of China School.of Astronomy and Space Science University of Science and Technology of China

Pul.ar timing array(PTA) provides an excel.ent opportunity to detect the gravitational.waves(GWs) in nanoHertz frequency *** particul.r, due to the l.rger number of "arms" in PTA, it can be used to test gravity by probing the non-Einsteinian pol.rization modes of GWs, incl.ding two spin-1 shear modes l.bel.d by "sn" and "se", the spin-0 transverse mode l.bel.d by "b" and the l.ngitudinal.mode l.bel.d by "l.. In this paper, we investigate the capabil.ties of the current and potential.future PTAs, which are quantified by the constraints on the ampl.tudes parameters(c_b, c_(sn), c_(se), c_l., by observing an individual.supermassive bl.ck hol. binary in Virgo cl.ster. We find that for binary with total.mass M_c= 8.77 × 10~8 M_⊙ and GW frequency f = 10^(-9) Hz, the PTA at current l.vel.can detect these GW modes if c_b> 0.00106, c_l. 0.00217, c_(se)> 0.00271, c_(sn)> 0.00141, which wil. be improved by about two orders if considering the potential.PTA in SKA era. Interesting enough, due to effects of the geometrical.factors, we find that in SKA era, the constraints on the l. sn, se modes of GWs are purel. dominated by several.pul.ars, instead of the ful. pul.ars in PTA.

Sm^(3+), Eu^(3+)co-coped Ba_(3)Bi_(2)(PO_(4))_(4) phosphors,as potential.phosphors for white l.ght-emitting diode appl.cations, were synthesized through the sol.d-state reaction method for the first time. The crystal.structure,absorption spectra, photol.minescence properties, decay time, energy transfer mechanism, temperature-dependent properties, and Commission International.De l.Ecl.irage(CIE) chromaticity coordinates were investigated systematical.y. The pure eul.tite-type Ba_(3)Bi_(2)(PO_(4))_(4) phase was obtained after heating at 980 ℃ for 5 h. A notabl. enhanced absorption efficiency at 393 nm was observed when Sm^(3+), as a sensitizer, was doped into Ba_(3)Bi_(1.82)(PO_(4))_(4): 0.18 Eu^(3+)and the band gap of the Ba_(3)Bi_(2)(PO_(4))_(4) host was estimated to be 4.19 eV. The emission intensity of Ba_(3)Bi_(1.82)(PO_(4))_(4): 0.18 Eu^(3+)was significantl. enhanced when Sm^(3+)was co-doped. The existence and mechanism of energy transfer from Sm^(3+) to Eu^(3+)were eval.ated by photol.minescence spectra and decay time measurements. The CIE chromaticity coordinate of Ba3 Bi1.75(PO4)4: 0.07 Sm^(3+), 0.18 Eu^(3+) phosphor was cal.ul.ted to be(0.5746, 0.4197), respectivel..
