The development of supramolecular hosts which can efficiently encapsulate photosensitizers to improve the photodynamic efficacy holds great promise for cancer ***,we report two perylene diimide-based metallacages that can form stable host–guest complexes with planar conjugated molecules including polycyclic aromatic hydrocarbons and photosensitizers(hypocrellin A).Such host–guest complexation not only prevents the aggregation of photosensitizers in aqueous environments,but also offers fluorescence resonance energy transfer(FRET)from the metallacage to the photosensitizers to further improve the singlet oxygen generation(Φ_(Δ)=0.66).The complexes are further assembled with amphiphilic polymers,forming nanoparticles with improved stability for anticancer *** in vitro and in vivo studies indicate that the nanoparticles display excellent anticancer activities upon light irradiation,showing great potential for cancer photodynamic *** study provides a straightforward and effective approach for enhancing the photosensitivity of conventional photosensitizers via host–guest complexation-based FRET,which will open a new avenue for host–guest chemistry-based supramolecular theranostics.

Emeishan large igneous province (ELIP),one of the largest continental volcanic provinces worldwide (e.g.,Karoo),is extensively distributed along the western margin of the Yangtze *** though the consensus that the ELIP is of a plume-related origin has been reached for decades,the role of crustal contamination in the petrogenesis of these basalts is still debatable so *** paper firstly reports the Ba isotopic compositions of the continental flood basalts from the Lijiang,Miyi and Emeishan regions to discuss the genesis of basalts from the *** to their TiO_(2) contents and Ti/Y ratios,these basalts are divided into two groups,the low-Ti basalts from Lijiang and the high-Ti basalts from Miyi and *** Ba isotopic compositions show that the low-Ti basalts have the δ^(138/134)Ba values from-0.33‰to+0.23‰with an average of-0.02‰±0.40‰,and the high-Ti basalts from -0.38‰to+0.38‰with an average of 0.038‰±0.36‰,all of which show a wider range of Ba isotopes relative to that of the primitive mantle (PM).This is unlikely to be explained by partial melting,fractional crystallization or even chemical weathering owing to little Ba isotopic fractionation during these *** contrast,variable extents of crustal contamination into the basaltic magmas more likely resulted in such isotopic *** ratios of incompatible elements (e.g.,Nb/U,La/Nb,and Nb/Y) further suggest that the low-Ti basalts experienced higher degrees of crustal contaminations than those high-Ti basalts,which is well consistent with their spatial *** general,the basaltic magmas in the ELIP were probably contaminated by different degrees of crustal materials during their upwelling to the surface.

玄武岩纤维被列为国家战略性资源,在各领域有广阔应用前景。但作为支撑产业发展的纤维用玄武岩原矿矿产勘查工作程度总体水平还较低,尤其是优质纤维用玄武岩的开采与评价标准仍有待完善。四川会理市龙肘山峨眉山玄武岩分布面积广,岩体厚度约3000余米,存在多层化学性质相对较稳定的致密块状玄武岩,可用于制备优质玄武岩纤维。为评价会理地区连续玄武岩纤维矿体质量,在野外调查的基础上,采用岩相学结合元素地球化学方法,探讨化学成分、特征参数工业指标及成因特征对纤维用玄武岩质量影响。研究结果表明:(1)会理地区玄武岩岩矿资源丰富,可作为优质玄武岩纤维原料的致密块状玄武岩厚度达1000余米,找矿前景巨大。(2)玄武岩样品w(SiO_(2))为47.01%~49.81%、w(TiO_(2))为2.79%~5.22%、w(CaO)为5.37%~11.22%、w(Al_(2)O_(3))为11.73%~14.87%、w(TFe_(2)O_(3))为12.79%~15.03%、w(Mg0)为3.53%~10.22%、w(Na,0+K0)为1.76%~5.04%,且酸度系数(Ma)为3.12~5.22,w(FeO/Fe_(2)O_(3))为0.90%~2.31%,w(SiO_(2)+Al_(2)O_(3))为61.08%~63.75%,原料具有适宜熔点和黏度,所制纤维具有良好稳定性和强度。(3)区内玄武岩属于碱性-亚碱性系列,微量、稀土元素特征与OIB型玄武岩相似,其玄武岩浆来源于大陆板内稳定的石榴石橄榄岩区,上升过程中未受到地壳同化混染,拉丝时原料具有稳定的硅酸盐结构。(4)会理地区玄武岩Li,Ni,Zn,Ce,Er5种元素含量适宜,可提高玄武岩纤维耐高温、抗腐蚀等性质。总之,会理地区玄武岩储量大,具有纤维用玄武岩矿石的良好赋存地质条件,且品质优良,可作为优质原料开采,研究成果对建立优质纤维用玄武岩地质勘查及矿石品质综合评价体系具有指导意义。

Formamidine lead triiodide(FAPbI_(3))perovskites have become the most promising photovoltaic materials for perovskite solar cells with record power conversion efficiency(PCE).However,random nucleation,phase transition,and lattice defects are still the key challenges limiting the quality of FAPbI_(3) *** studies show that the introduction or adding of seeds in the precursor is effective to promote the nucleation and crystallization of perovskite ***,the seed-assisted approach focuses on heterogeneous seeds or hetero-composites,which inevitably induce a lattice-mismatch,the genera-tion of strain or defects,and the phase segregation in the perovskite ***,we first demonstrate that high-quality perovskite films are controllably prepared using α-and δ-phases mixed FAPbI_(3) micro-crystal as the homogeneous seeds with the one-step antisolvent *** partially dissolved seeds with suitable sizes improve the crystallinity of the perovskite flm with preferable orientation,improved carrier lifetime,and increased carrier *** importantly,the α-phase-containing seeds promote the formation of α-phase FAPbI_(3) films,leading to the reduction of residual lattice strain and the suppres-sion of I-ion ***,the adding of dimethyl 2,6-pyridine dicarboxylate(DPD)into the pre-cursor further suppresses the generation of defects,contributing to the PCE of devices prepared in air ambient being significantly improved to 23.75%,among the highest PCEs for fully air-processed FAPbI_(3) solar *** unpackaged target devices possess a high stability,maintaining 80%of the initial PCE under simulated solar illumination exceeding 800 h.

通过对云南大湾金矿地球化学特征的研究,认为Au与As、Sb、Hg元素呈正相关关系,尤其与As的相关性较好,与Hg的相关性较弱;Au与Cu、Co、Ni 3种元素呈负相关。用R型因子分析法和元素叠加异常法分别对异常进行了组合异常的圈定,对2种方法进行了对比研究,因子得分圈定组合异常能更准确和直观地反映组合异常浓集中心的位置,但圈定的异常范围较大,无法判断明确的浓集中心,利用异常下限划分出来的异常范围较为真实。

Lanping basin is located between Lancangjiang fault and Jinshajiang fault. Himalayan movement is the important tectogenesis, during which the activity of mid\|alkali magma is strong. For a long time, because the previous had focused on studying porphyry copper, lead, zinc multi metal ore deposit in east uplift to this area, and they had ignored the relationship between Himalayan tectonomagnetic movement and multi\|metal mineralization in the basin.1 Characteristic of the Himalayan magmatic rock Himalayan magmatic rocks, a part of Himalayan porphyry zone, mainly distributed along Lijiang\|Beiya\|Weishan, which is the east to Lanping basin. There are a few magmatic rocks in the basin, a big scale of which is Yongping Zhuopan rock body, Yunlong Zaojiaochang rock body and Eryuan Shangyicun rock body. These magmatic rocks are mainly intrusion rocks and their characteristics are quartz syenite porphyry, alkalic rock, and granite porphyry. The ratio 87 Sr/ 86 Sr of rocks is 0 7046～0 7084, which reflects the magma source comes from *** average isotopic age of these magmatic rocks is 40Ma. For example, Zhuopan rock body’s age of K\|Ar is 33 8Ma, Weishan rock body’s age of K\|Ar is 46 9Ma.
