Appropriate materials collaborated with reasonable structure can significantly increase the separator performance for lithium-ion *** this work,taking the advantages of microfibrous and nanofibrous membranes and compensating for their defects,we developed a composited separator(GOPPH)with excellent overall performance by first wetting-modifying the polyethylene terephthalate microfibers and then laminating a polyvinylidene fluoride-hexafluoropropylene nanofiber *** a combination not only offers the GOPPH separator,from the perspective of structure,with high porosity and hierarchical structure in terms of fiber diameter and pore size,but also provides satisfactory features including wettability,mechanical strength and thermal shutdown function that benefit from the selected ***,as determined by experimental and theoretical approaches,the obtained GOPPH separator exhibits considerably enhanced lithium ion transport ability with a high lithium ion transference number and transport rate,which thereby endowing the cell with superior cycling stability with a capacity retention of 93%after 200 cycles at 1 ***,considering battery safety and performance,the GOPPH fibrous membrane could be a promising separator candidate for lithium-ion batteries.

In the impact melt breccia(IMB) of Sayh al Uhaymir(SaU) 169,the most KREEP-rich lunar meteorite to date(Gnos et al.,2004),clasts of a new type of lithologies were discovered,consisting of ca-poor and ca-rich pyroxenes(60.8 vol.%), Ba-rich K-feldspar(27.9 vol.%),phosphates(5.6 vol.%),Nb-rich ilmenite(4.0 vol.%),zircon(1.2 vol.%) and minor sulfide (0.6 vol.%).These mafic lithic clasts are more enriched in KREEP component(～1500×cI) than the host meteorite and are highly enriched in *** are referred to as very high-K(VHK) KREEP lithology,and probably most close to the last residual liquid of the Lunar Magma Ocean without significant dilution by other Mg-rich *** fine-grained matrix of the SaU 169 IMB has very similar mineral chemistry to the VHK KREEP lithology,but contains abundant plagioclase with trace *** matrix shows decoupling of K from the REEP-like component;however,it cannot be simply interpreted by mixing the VHK KREEP lithology with anorthosites,which should have diluted the REEP-like component with the same proportion.

InN films with highly c-axis preferred orientation were deposited on sapphire substrate by low-temperature electron cyclotron resonance plasma-enhanced metal organic chemical vapor deposition (EcR-PEMOcVD). Trimethyl indium (TMIn) and N 2 were applied as precursors of In and N, respectively. The quality of as-grown InN films were systematically investigated as a function of TMIn fluxes by means of reflection high-energy electron diffraction (RHEED), X-ray diffraction analysis (XRD), and atomic force microscopy (AFM). The results show that the dense and uniform InN films with highly c-axis preferred orientation are successfully achieved on sapphire substrates under optimized TMIn flux of 0.8 ml min 1 . The InN films reported here will provide various opportunities for the development of high efficiency and high-performance semiconductor devices based on InN material.

An in vitro blood-brain barrier(BBB) model is critical for enabling rapid screening of the BBB permeability of the drugs targeting on the central nervous *** many models have been developed, their reproducibility and renewability remain a challenge. Furthermore, drug transport data from many of the models do not correlate well with the data for in vivo BBB drug ***-pluripotent stem cell(i PSc) technology provides reproducible cell resources for in vitro BBB ***, we generated a human in vitro BBB model by differentiating the human i PSc(hi PSc) line GM25256 into brain endothelial-type cells. The model displayed BBB characteristics including tight junction proteins(ZO-1,claudin-5, and occludin) and endothelial markers(von Willebrand factor and Ulex), as well as high transendothelial electrical resistance(TEER)(1560 ***2±230 ***2) and c-GTPase activity. co-culture with primary rat astrocytes significantly increased the TEER of the model(2970 ***2 to 4185 ***2). RNAseq analysis confirmed the expression of key BBB-related genes in the hi PSc-derived endothelial cells in comparison with primary human brain microvascular endothelial cells,including P-glycoprotein(Pgp) and breast cancer resistant protein(BcRP). Drug transport assays for nine cNS compounds showed that the permeability of non-Pgp/BcRP and Pgp/BcRP substrates across the model was strongly correlated with rodent in situ brain perfusion data for these compounds(R2= 0.982 and R2= 0.9973,respectively), demonstrating the functionality of the drug transporters in the model. Thus, this model may be used to rapidly screen cNS compounds, to predict the in vivo BBB permeability of these compounds and to study the biology of the BBB.

Hemagglutinin-neuramidinase（HN） is one of the most important surface structure proteins of the Newcastle disease virus（NDV）. HN not only mediates receptor recognition but also possesses neuraminidase（NA） activity, which gives it the ability to cleave a component of those receptors, NAcneu. Previous studies have demonstrated that HN has interesting anti-neoplastic and immune-stimulating properties in mammalian species, including humans. To explore the application of the HN gene in cancer gene therapy, we constructed a Lewis lung carcinoma（LLc） solid tumor model using c57BL/6 mice. Mice were injected intratumorally with the recombinant adenovirus expressing HN gene（Ad-HN）, and the effect of HN was explored by natural killer cell activity assay, cytotoxic lymphocyte activity assay, T cell subtype evaluation, and Th1/Th2 cytokines analysis. The results demonstrate that HN not only can elicit clonal expansion of both cD4＋ and cD8＋ T cell populations and cytotoxic T lymphocyte（cTL） and killer cell response, but also skews the immune response toward Th1. Thus, vaccination with Ad-HN may be a potential strategy for cancer gene therapy.
