| 1 | Discovery of eclogite inclusions and its geological significance in early Jurassic intrusive complex in Xuzhou-northern Anhui, eastern China显示文摘The early Jurassic intrusive complex is chiefly made of monzodioritic porphyry in northern Anhui and northern Jiangsu, which emplaced in 191 Ma. The intrusive complexes contain a lot of eclogite inclusions which belong to eclogite and garnet-pyroxenite. The inclusions had undergone eclogite facies high-pressure metamorphism and am-phibolite facies retrogressive metamorphism. The garnets in eclogite inclusions are mainly almandine varieties and clino-pyroxenes are omphacite and augite. The mineral assemblage and P-T estimation results show that P-T conditions of eclogite facies metamorphism and amphibolite facies retrogressive metamorphism are over 1.2-1.5 GPa, 709-861°C and 0.7-1.03 GPa, 666-738°C, respectively. The discovery of the high-pressure xenoliths not only is of important significance to understand the composition and structure of deep crust in southern edge of North China Platform, but also can be of important influence on realizing the subduc-tion-collision-exhumation evolutional process | Wenliang Xu Dongyan Wang Xiaochun Liu Qinghai Wang Jingqian Lin | 2002 | Chinese Science Bulletin2002，47，14： | 37 |
| 2 | Inclusion complexes of cefuroxime axetil with β-cyclodextrin:Physicochemical characterization, molecular modeling and effect of Larginine on complexation显示文摘The inclusion complexes of poorly water-soluble cephalosporin, cefuroxime axetil(CFA), were prepared with β-cyclodextrin(βCD) with or without addition of L-arginine(ARG) to improve its physicochemical properties. We also investigated the effect of ARG on complexation efficiency(CE) of βCD towards CFA in an aqueous medium through phase solubility behaviour according to Higuchi and Connors. Although phase solubility studies showed AL(linear) type of solubility curve in presence and absence of ARG, the CE and association constant(Ks) of βCD towards CFA were significantly promoted in presence of ARG,justifying its use as a ternary component. The solid systems of CFA with βCD were obtained by spray drying technique with or without incorporation of ARG and characterized by differential scanning calorimetry(DSC), X-ray powder diffractometry(XRPD), scanning electron microscopy(SEM), and saturation solubility and dissolution studies. The molecular modeling studies provided a better insight into geometry and inclusion mode of CFA inside βCD cavity. The solubility and dissolution rate of CFA were significantly improved upon complexation with βCD as compared to CFA alone. However, ternary system incorporated with ARG performed better than binary system in physicochemical evaluation. In conclusion, ARG could be exploited as a ternary component to improve the physicochemical properties of CFA via βCD complexation. | Sarika Sapte Yogesh Pore | 2016 | Journal of Pharmaceutical Analysis2016，6，5： | 3 |
| 3 | Fluid-induced high-temperature metasomatism at Rundv?gshetta in the Lützow-Holm Complex, East Antarctica: Implications for the role of brine during granulite formation显示文摘We report new petrological, phase equilibria modeling, and fluid inclusion data for pelitic and mafic granulites from Rundv?gshetta in the highest-grade region of the Neoproterozoic Lützow-Holm Complex(LHC),East Antarctica, and provide unequivocal evidence for fluid-rock interaction and high-temperature metasomatism in the presence of brine fluid. The studied locality is composed dominantly of well-foliated pelitic granulite(K-feldspar+quartz+sillimanite+garnet+ilmenite) with foliation-parallel bands and/or layers of mafic granulite(plagioclase+orthopyroxene+garnet+ilmenite+quartz+biotite). The boundary between the two lithologies is defined by thin(about 1 -20 cm in thick) garnet-rich layers with a common mineral assemblage of garnet+plagioclase+quartz+ilmenite+biotite ? orthopyroxene. Systematic increase of grossular and decrease of pyrope contents in garnet as well as decreasing Mg/(Fe+Mg) ratio of biotite from the pelitic granulite to garnet-rich rock and mafic granulite suggest that the garnet-rich layer was formed by metasomatic interaction between the two granulite lithologies. Phase equilibria modeling in the system NCKFMASHTO demonstrates that the metasomatism took place at 850 -860℃, which is slightly lower than the peak metamorphism of this region, and the modal abundance of garnet is the highest along the metapeliteemetabasite boundary(up to 40%), which is consistent with the field and thin section observations. The occurrence of brine(7.0 -10.9 wt.% Na Cleqfor ice melting or 25.1 -25.5 wt.% NaC leqfor hydrohalite melting) fluid inclusions as a primary phase trapped within plagioclase in the garnet-rich layer and the occurrence of Cl-rich biotite(Cl = 0.22 -0.60 wt.%) in the metasomatic rock compared to that in pelitic(0.15 -0.24 wt.%) and mafic(0.06-0.13 wt.%) granulites suggest infiltration of brine fluid could have given rise to the high-temperature metasomatism. The fluid might have been derived from external sources possibly related to the formation of major suture zones formed during the Gondwana amalgamation. | Kazuki Takahashi Toshiaki Tsunogae Emmanuel Nwachukwu Ugwuonah | 2018 | Geoscience Frontiers2018，9，5： | 2 |

| 6 | Inclusion complexes between sildenafil citrate and cyclodextrins enhance drug solubility显示文摘Sildenafil citrate is a potent and selective phosphodiesterase-5inhibitor. It is effectively used in the treatment of erectile dysfunction and pulmonary arterial hypertension. The drug is rapidly absorbed and pharmacologically acts within30 min to 1 h after oral administration. However, it has a relatively low absolute bioavailability of 41%because its limited solubility in water is the major problem (1)To improve the oral bioavailability of poorly water-soluble drugs. | Apichart Atipairin Somchai Sawatdee | 2016 | Asian Journal of Pharmaceutical Sciences2016，11，1： | 1 |
| 7 | Coaxing Polysaccharide Granules into Supramolecular Biocolloidal Additives for Papermaking显示文摘In light of developments in polysaccharide-based sustainable processes involving supramolecular interactions,we herein present our findings pertaining to coaxing polysaccharide granules into functional supramolecular biocolloids.Translucent biocolloidal dispersions containing various forms of starch are facilely designable,essentially built upon complexation between disassembled native cornstarch granules and amphiphilic ligands.Oily moieties of guest molecules are dynamically attractable into cavities of helical structures,with cationic groups pointing toward the bulk phase.This noncovalent attraction can generate core-shell biocolloidal particles.The significantly higher gelatinizability of freeze-dried biocolloids in contrast to native cornstarch granules is attributable to complex formation,and a homogenous dispersion is readily formable at room temperature.Our results also show biocolloids'ligand-related antibacterial activity.The use of biocolloids as wet-end additives for biofiber assemblies(cellulosic paper)can enhance mechanical strength,fines retention,and filler bondability.Supramolecular biocolloids with positively charged,translucent,easily gelatinizable,antibacterial,and polysaccharide-bondable functionalities would find tailorable use in the paper industry. | Yongsheng Wang Wenyuan Zhu Xueren Qian Meiyun Zhang Shunxi Song Chuyan Jing Zhengren Meng Shiyu Xu Xianhui An Xiujie Huang Jing Shen | 2020 | Paper And Biomaterials2020，5，2： | 1 |
| 8 | Stabilization of Plutonium(V)Within a Crown Ether Inclusion Complex显示文摘Crystalline coordination complexes of actinides,especially in atypical oxidation states,are not only fundamentally important for expanding the notably limited knowledge on the bonding nature of actinides but could also provide critical information toward the development of nuclear fuel cycle,waste management,and national security.Plutonium(Pu)is the only element in the periodic table that could exist in four oxidation states in aqueous solutions simultaneously. | Yaxing Wang Shu-Xian Hu Liwei Cheng Chengyu Liang Xuemiao Yin Hailong Zhang Ao Li Daopeng Sheng Juan Diwu Xiaolin Wang Jun Li Zhifang Chai Shuao Wang | 2020 | CCS Chemistry2020，2，4： | 1 |
| 9 | Studies on the Intramolecular Inclusion Complexes of Functionalized Calixarenes with CH_3X (X=CN, NO_2)显示文摘Two functionalized calixarenes in cone conformation L 2-3 have been synthesized and their intramolecular inclusion complexes (1∶1) with organic neutral molecules CH 3CN and CH 3NO 2 have been prepared and characterized, respectively. The X-ray crystallographic analysis shows that L 2 in L 2·CH 3CN·C 2H 5OH has C 4 symmestry and L 3 in L 3·CH 3NO 2 exhibits C 2 symmestry. The CH-π aromatic interactions between the CH group of the guest and the phenyl rings of the calix backbond have been proved to be able to stabilize the intramolecular inclusion complexes formed. The interaction is directional, but it is independent of the acidity of the guest. To gain information on CH-π interactions, suitable geometrical parameters have been calculated from the crystal data of intramolecular inclusion complexes. The results show that L 3·CH 3NO 2 with L 3 in C 2 symmestry can also be bound stably in the intramolecular inclusion complex, being consistent with the thermal analysis. The geometrical parameters and the results of the thermal analysis of L 1·CH 3CN and L 1·CH 3NO 2 were also given and discussed. | 周稚仙 石雅琳 杜晨霞 邢彦军 吴养洁 | 2002 | Chinese Journal of Chemistry2002，20，11： | 1 |

| 11 | Synthesis and inclusion properties of amphiphilic calixarenes显示文摘Study of host-guest interaction with the aid of proper model system is helpful to the understanding of complicated chemical reactions in biological processes on the molecular level. Cyclodextrins and crown ethers are two kinds of the most extensively studied host molecules and enzyme mimics. The cyclodextrins are very hydrophilic on their out rims but lipophilic on the inner remainder; the crown ethers are highly lipophilic on the outside and hydrophilic on the inside. In recent years, calixarene has been found a new kind of host compounds, which can form host-guest inclusion complexes with many kinds of | 石有恒 王夺元 | 1996 | Chinese Science Bulletin1996，41，3： | 0 |
| 12 | AN INTERFACE INCLUSION BETWEEN TWO DISSIMILAR PIEZOELECTRIC MATERIALS显示文摘The generalized two- dimensional problem of a dielectric rigid line inclusion, atthe interface between two dissimilar piezoelectric media subjected to piecewise uniform loads at infinity, is studied by means of the Stroh theory. The problem was reduced to a Hilbert problem, and then closed-form expressions were obtained, respectively, for the complex potentials in piezoelectric media, the electric field inside the inclusion and the tip fields near the inclusion. It is shown that in the media, all field variables near the inclusion-tip show square root singularity and oscillatory singularity, the intensity of which is dependent on the material constants and the strains at infinity. In addition, it is found that the electric field inside the inclusion is singular and oscillatory too, when approaching the inclusion-tips from inside the inclusion. | GAO Cun-fa(高存法) FAN Wei-xun(樊蔚勋) | 2001 | Applied Mathematics and Mechanics(English Edition)2001，22，1： | 0 |

| 16 | Salt/current-triggered stabilization of β-cyclodextrins encapsulated host-guest low-molecular-weight gels显示文摘Host-guest supramolecular gels were developed via the self-assembly of inclusion complexes(ICs) ofβ-cyclodextrins/phenylboronic acid gelator(PBA).Salts and current were involved in the self-assembly to stabilize the host-guest gels.The stability of the gels was greatly improved after salts were added.The stable time of gels was extended from 2.5 h to 120 h with the addition of NH_4 NO_3 at the concentration of 2.5×10^(-2) g/mL.The morphology of the gel was affected by the concentrations of NH_4NO_3.SEM images revealed that the gels were three-dimensional nanofibrous networks,the sizes of fibers decreased with decreasing NH_4NO_3 concentrations,which affected the stability of gels,further proved by the rheological properties of gels.More stable gels were obtained with current stimulation,the stable time of the gel was increased from 2.5 h to 55 h with current by adding NaBF_4.The current also exhibited significant influence on the aggregation as the voltage varied(0-500 mV) with a constant concentration of salts.The result showed the self-assembly process of host-guest gel could be well controlled via the addition of salts and current to desired morphology and stability. | Huan Xu Chaoyu Zhou Chuanjiang Jian Sunhai Yang Miaochang Liu Xiaobo Huang Wenxia Gao Huayue Wu | 2020 | Chinese Chemical Letters2020，31，2： | 0 |

| 19 | Intermolecular and intramolecular electron transfer from eosin ester to viologen显示文摘The covalently -(CH2)10- linked eosin-butylviologen compound has been synthesized. The photoinduced electron transfer of eosin ester and butylviologen as well as the influence of addition of cyclodextrin or amylose into the solution of linked compound on the system have been studied by the absorption spectra, fluorescence spectra and fluorescence lifetime. The results indicated that the intramolecular electron transfer is much more efficient than the intermolecular one. Due to the formation of inclusion complex, the process of intramolecular electron transfer was changed after adding cydodextrin or amylose. | 张丰雷 张曼华 沈涛 | 1996 | Science China Chemistry1996，39，6： | 0 |
