| 2 | Optimal bulk-heterojunction morphology enabled by fibril network strategy for high-performance organic solar cells显示文摘A bicontinuous network formed spontaneously upon film preparation is highly desirable for bulk-heterojunction(BHJ) organic solar cells(OSCs). Many donor-acceptor(D-A) type conjugated polymers can self-assemble into polymer fibrils in the solid state and such fibril-assembly can construct the morphological framework by forming a network structure, inducing the formation of ideal BHJ morphology. Our recent works have revealed that the fibril network strategy(FNS) can control the blend morphology in fullerene, non-fullerene and ternary OSCs. It has been shown that the formation of fibril network can optimize phase separation scale and ensure efficient exciton dissociation and charge carriers transport, thus leading to impressive power conversion efficiencies(PCEs) and high fill factor(FF) values. We believe that FNS will provide a promising approach for the optimization of active layer morphology and the improvement of photovoltaic performance, and further promote the commercialization of OSCs. | Tian Xia Yunhao Cai Huiting Fu Yanming Sun | 2019 | Science China Chemistry2019，62，6： | 4 |
| 3 | Petroleum exploration breakthrough and geological significance in Cretaceous Yingcheng and Denglouku formations of Shuangcheng area, northern Songliao Basin, NE China显示文摘Based on drilling geological,geochemical,geophysical and production test data,the characteristics of source rocks,reservoir rocks and caprocks,as well as the process of hydrocarbon generation,trap evolution and oil accumulation of the oil-bearing assemblage composed of the Cretaceous Yingcheng Formation(K1yc)and Denglouku Formation(K1d)in the Shuangcheng area,northern Songliao Basin,NE China,were analyzed by using the research methods for petroleum systems.The source rocks mainly exist in K1yc,with the organic matters mainly originated from lower aquatic organisms and algae,and reaching the grade of high-quality source rock in terms of organic abundance.The crude oil,which is characterized by low density,high freezing point and high wax content,is believed to have generated by the K1yc source rocks.The reservoir rocks include K1d sandstones and K1yc glutenites.The mudstone in the fourth member of K1d serves as the direct caprock of the oil reservoir.The oil was generated during the period between Yaojia Formation and Nenjiang Formation,and then accumulated during the periods of Nenjiang Formation and Paleogene–Neogene.The traps evolved in three stages:the late Yingcheng Formation,the late Quantou Formation and the late Nenjiang Formation,forming structural and structural-lithologic reservoirs.It is concluded that good source-reservoir-caprock assemblage,late hydrocarbon charging,short migration distance and stable tectonic setting are favorable factors for the formation of oil reservoirs. | LIU Chao FU Xiaofei LI Yangcheng WANG Haixue SUN Lidong LU Jiamin LI Junhui SUN Youhai SHI Lidong HU Huiting YUAN Hongqi YANG Zicheng | 2023 | Petroleum Exploration and Development2023，50，1： | 0 |
| 4 | Rational design of smart adsorbent equipped with a sensitive indicator via ligand exchange:A hierarchical porous mixed-ligand MOF for simultaneous removal and detection of Hg^(2+)显示文摘The increasing accumulation of toxic mercury species in water environment has posed a serious health threat worldwide, making it inevitable to develop the versatile materials to achieve efficient prevention and remediation of mercury pollution. Guided by the solvent-assisted ligand exchange (SALE) approach, this work rationally constructed a mixed-ligand NH2-UiO-66-SH (NSU66) with hierarchical-pore structure by incorporating the thiol-rich ligands (H2DMBD) into the water-stable NH2-UiO-66 (NU66) precursor to act as a smart adsorbent equipped with sensitive detector for simultaneous sensing and removal of Hg2+. Unlike the traditional adsorbents, the as-prepared NSU66 not only exhibits a remarkable removal ability with fast capture rate (within 60.0 min), large uptake capacity (265.29 mg/g), and qualified selectivity, but also possesses satisfactory sensing capability, accompanied by low detection limit (3.50 × 10−2 µM), wide linear range (1.00–99.7 µM), high specificity, and strong anti-interference capability. The detection function plays a vital role in indicating the removal behavior and the pre-enrichment effect of adsorption process correspondingly improves the sensitivity of indicator. Notably, the sensing and trapping capabilities of NSU66 are significantly improved compared to the NU66, which stems from the delicate design of the mixed-ligand and hierarchical-pore structure. Furthermore, proven excellent stability and recyclability emphasize the feasibility of NSU66 in practical applications. These results suggest that the smart NSU66 adsorbent can serve as a favorable platform for early warning and guided removal of toxic Hg2+ in water. | Liang Zhang Jing Wang Huiting Wang Wentao Zhang Wenxin Zhu Ting Du Yongsheng Ni Xianghong Xie Jing Sun Jianlong Wang | 2021 | Nano Research2021，14，5： | 0 |
| 5 | Molecular rotaxane shuttle-relay accelerates K^(+)/Cl^(-) symport across a lipid membrane显示文摘Synthetic molecules that can mediate the coupled transport of Cl^(-) with K^(+) and/or Na+across the lipid bilayers have aroused great interest due to their potential as a novel therapeutic strategy by disrupting cellular ion homeostasis.Based on the structural advantages of molecular rotaxanes,we herein show that two rotaxane-based transporters[2]R and[3]R induce coupled K^(+)/Cl^(-) channel transport by introducing Cl^(-) recognition sites in the thread and K^(+) binding group in the wheel,respectively.The welldesigned molecular structures allow the insertion of unimolecular rotaxanes into the lipid bilayer,thus achieving effective ion transport by means of thermodynamically controlled movement and driven by the difference in ion concentration inside and outside the vesicles.In addition,the use of a three-component rotaxane can accelerate ion transport through a cooperative shuttlerelay mechanism in which two wheels move along the thread in the lipid membrane,thereby enabling[3]R to have higher ion transport capacity.This work represents a major advance in the use of rotaxane molecules to accomplish more complex and effective tasks. | Kai Ye Zekai Zhang Zexin Yan Shihao Pang Huiting Yang Xiaonan Sun Can Liu Linyong Zhu Cheng Lian Chunyan Bao | 2023 | Science China Chemistry2023，66，8： | 0 |
