| 1 | The response of deltaic systems to climatic and hydrological changes in Daihai Lake rift basin,Inner Mongolia,northern China显示文摘Delta systems are ubiquitous around lacustrine rift basins. Its peripheral ge-ometry, progradation structures and sedimentary successions were controlled by both tec-tonic settings and climatic changes. Peripheral geometry of a delta was strongly influenced by depositional gradients which formed the fan-shape delta on the steep slopes and developed the lobe-shape delta on the gentle slopes. Due to the discharge feed rivers can change rapidly driven by climatic variations, and the nearshore area of deltas display considerable facies variability. The rise of annual rainfall, which suggests the rivers feeding deltas are continuous, and result in distributary mouth bars that are prevalent in the front of deltas since the down-slope flows are greater than the along-slope currents. On the contrary, when the annual rainfall decreases and evaporation increases, the rivers only can feed deltas ephemerally. If the along-slope currents were in a dominant position, the distal bars were deposited. Progra-dation structure and sedimentary successions of deltas were controlled by the gradients of slopes. On gentle depositional slopes, shingle foreset beds predominate with fine sediments and small-scale sedimentary structures or vice versa. | Yu Xinghe Li Shunli Tan Chengpeng Xie Jing Chen Bintao Yang Fan | 2013 | Journal of Palaeogeography2013，2，1： | 6 |

| 5 | A universal strategy for achieving dual cross-linked networks to obtain ultralong polymeric room temperature phosphorescence显示文摘Efficient polymeric room-temperature phosphorescence(PRTP)with excellent processability and flexibility is highly desirable but still faces formidable challenge.Herein,a general strategy is developed for efficient PRTP through photo-polymerization of phosphor monomers and N-isopropylacrylamide(NIPAM)spontaneously without a crosslinker.Remarkably ultralong lifetime of 3.54 s with afterglow duration time of 25 s and decent phosphorescent quantum efficiency of 13%are achieved.This efficient PRTP has been demonstrated to be derived from the synergistic effect of the covalent and hydrogen bonds networks formed through photo-polymerization of NIPAM.The electron paramagnetic resonance(EPR)spectra confirmed that methyl radicals are generated under the irradiation of ultraviolet light and promote the formation of covalent cross-linking networks.This strategy has also been proved to be generalizable to several other phosphor monomers.Interestingly,the polymer films display ultrahigh temperature resistance with long afterglows even at 140℃ and unexampled ultralong lifetime of 2.45 s in aqueous solutions.This work provides a simple and feasible avenue to obtain efficient PRTP. | Yifan Niu Yan Guan Chunye Long Chaofan Ren Jiwen Lu Chanjuan Jin Ping Wang Xinghe Fan He-Lou Xie | 2023 | Science China Chemistry2023，66，4： | 0 |
| 6 | Restudy of the unusual phase behavior of the mesogen-jacketed liquid crystal polymers显示文摘A series of poly{2,5-bis[(4-butoxyphenyl)-oxycarbonyl]styrenes} (PBPCS) with low mo-lecular weight distribution was synthesized by atom transfer radical polymerization (ATRP). The me-somorphic properties were investigated by differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and rheometer. PBPCS showed the phase transition from isotropic into liquid crystal (LC) phase, and the LC phase formed at high temperature and disappeared in the subsequent cooling procedure. Using the WAXD fiber pattern, the phase structure of the PBPCS at higher tem-perature showed hexagonal columnar nematic phase. Experimental results demonstrated that the driving force of the entropy is an important factor during the unusual LC phase formation of PBPCS. | ZHAO Yongfeng FAN Xinghe CHEN Xiaofang WAN Xinhua ZHOU Qifeng | 2006 | Science China Chemistry2006，49，2： | 0 |
| 7 | Classification of mass-transport complexes and distribution of gashydrate-bearing sediments in the northeastern continental slope of the South China Sea显示文摘The drilling areas in Shenhu and Dongsha,South China Sea,studied from 2007 to 2015,reveal great heterogeneity in the spatial distribution of the gas hydrate reservoir.Various types of mass-transport complexes(MTCs)were developed in the study areas,which served as ideal reservoirs.To conduct exploration in these areas,it is necessary to study the different types of MTCs and the corresponding gashydrate accumulations.By integrating seismic reflection and log coring data,we classified three types of MTCs according to their stress distribution:the tension,extrusion,and shear types,and their corresponding gashydrate accumulation patterns.The results show that the accumulation of the gas-hydrate varies with the type of MTC and stress distribution depending on the MTC’s position(e.g.,in the headwall,translational,or toe areas).Owing to this variance of the MTC’s position,the corresponding kinemics situation in the MTCs also varies.Accordingly,we determined the corresponding location in which the gashydrate develops for various types of MTCs.Based on the bottom simulating reflectors(BSRs)and the hydrate core and image logging data,the gashydrate reservoir shows an obvious heterogeneity in various types of MTCs.The gashydrate in the tension-type MTCs are mostly borne in the toe and the headwall parts.In extrusion-type MTCs,the translational and toe parts constitute an ideal hydrate reservoir.In shear-type MTCs,the headwall and toe parts’coarse-grained sediments show an obviously hydrate response.After comparing the gashydrate saturation and MTCs morphology statics data,we were able to quantitatively prove that the main factors determining gashydrate accumulation in the different types of MTCs are the fault displacement,sedimentary rate,and flow erosion rate. | Chao FU Xinghe YU Xue FAN Yulin HE Jinqiang LIANG Shunli LI | 2020 | Frontiers of Earth Science2020，14，1： | 0 |
