| 1 | 3D hierarchically porous NiO/Graphene hybrid paper anode for long-life and high rate cycling flexible Li-ion batteries显示文摘With the rapid emergence of wearable devices, flexible lithium-ion batteries(LIBs) are much more needed than ever. Free-standing graphene-based composite paper electrodes with various active materials have appealed wide applications in flexible LIBs. However, due to the prone-to-restacking feature of graphene layers, a long cycle life at high current densities is rather difficult to be achieved. Herein, a unique threedimensional(3D) hierarchically porous NiO micro-flowers/graphene paper(fNiO/GP) electrode is successfully fabricated. The resulting fNiO/GP electrode shows superior long-term cycling stability at high rates(e.g., storage capacity of 359 mAh/g after 600 cycles at a high current density of 1 A/g). The facile 3D porous structure combines both the advantages of the graphene that is highly conductive and flexible to ensure rapid electrons/ions transfer and buffer the volume expansion of NiO during charge/discharge,and of the micro-sized NiO flowers that induces hierarchical between-layer pores ranging from nanomicro meters to promote the penetration of the electrolyte and prevent the re-stacking of graphene layers. Such structural design will inspire future manufacture of a wide range of active materials/graphene composite electrodes for high performance flexible LIBs. | Ju Fu Wenbin Kang Xiaodong Guo Hao Wen Tianbiao Zeng Ruoxin Yuan Chuhong Zhang | 2020 | Journal of Energy Chemistry2020,29,8: | 5 |

| 3 | Sedimentary characteristics of distributive fluvial system in arid area: A case study of the Shule River distributive fluvial system, NW China显示文摘Based on detailed investigation of the modern sedimentation of the distributive fluvial system of Shule River and the data of unmanned aerial vehicle(UAV)aerial photography and satellite remote sensing,the sedimentary characteristics and differences of distributive fluvial system in arid areas are analyzed.By comparing the changes in slope,river morphology and sedimentary characteristics in different sections from the apex to the toe,the distributive fluvial system of Shule River can be divided into three facies belts:'proximal','middle'and'distal'.The proximal belt has the largest slope and strongest hydrodynamic condition,mainly appears as large-scale braided river deposits;the fluvial bars in this belt are mainly composed of gravels,the gravels have good roundness and certain directionality,and are medium-large boulders,with low sand content;the main microfacies in this belt are braided channel and flood plain.The middle belt with slope smaller than the proximal belt,is mainly composed of braided bifurcating river deposits.Due to branching and infiltration,this belt has weaker hydrodynamic conditions,so some of the distributive rivers dry up,appearing as ephemeral rivers.This belt has small lenticular sandbodies,fine to medium gravels,higher sand content,and mainly braided channel,flood plain and aeolian dune microfacies.The distal belt has the smallest slope and flat terrain,where the river begins to transform from braided river to meandering river,the sediment is mainly sand.Due to the influence of slope,this belt has weaker erosion toward source and stronger lateral erosion,and point bars developing around the edge of the active lobes.In this belt,the river is completely meandering,and the main microfacies are braided channel,meandering channel,flood plain,aeolian dune,lake and swamp. | ZHANG Xianghui ZHANG Changmin FENG Wenjie XU Qinghai ZHU Rui LIU Shuai HUANG Ruoxin | 2021 | Petroleum Exploration and Development2021,48,4: | 1 |
| 4 | Revealing the Distribution of Aggregation-Induced Emission Nanoparticles via Dual-Modality Imaging with Fluorescence and Mass Spectrometry显示文摘Aggregation-induced emission nanoparticles(AIE NPs)are widely used in the biomedical field.However,understanding the biological process of AIE NPs via fluorescence imaging is challenging because of the strong background and poor penetration depth.Herein,we present a novel dual-modality imaging strategy that combines fluorescence imaging and label-free laser desorption/ionization mass spectrometry imaging(LDI MSI)to map and quantify the biodistribution of AIE NPs(TPAFN-F127 NPs)by monitoring the intrinsic photoluminescence and mass spectrometry signal of the AIE molecule.We discovered that TPAFN-F127 NPs were predominantly distributed in the liver and spleen,and most gradually excreted from the body after 5 days.The accumulation and retention of TPAFN-F127 NPs in tumor sites were also confirmed in a tumor-bearing mouse model.As a proof of concept,the suborgan distribution of TPAFN-F127 NPs in the spleen was visualized by LDI MSI,and the results revealed that TPAFN-F127 NPs were mainly distributed in the red pulp of the spleen with extremely high concentrations within the marginal zone.The in vivo toxicity test demonstrated that TPAFN-F127 NPs are nontoxic for a long-term exposure.This dual-modality imaging strategy provides some insights into the fine distribution of AIE NPs and might also be extended to other polymeric NPs to evaluate their distribution and drug release behaviors in vivo. | Liucheng Mao Yuming Jiang Hui Ouyang Yulin Feng Ruoxin Li Xiaoyong Zhang Zongxiu Nie Yen Wei | 2021 | Research2021,,1: | 1 |
| 5 | PROX1 restrains ferroptosis via SCD transcription activation in colorectal cancer显示文摘Colorectal cancer(CRC)is one of the most commonly diagnosed cancers and the second most common cause of cancer-related mortality worldwide.Although several therapeutic approaches have been developed for CRC in recent years,the prognosis of patients who develop chemotherapy resistance remains poor.Ferroptosis is an iron and lipid reactive oxygen species(ROS)-dependent form of programmed cell death,and it is distinct from other forms of regulatory cell death at multiple levels[1].Ferroptosis is regulated by a complex network and is a research hotspot as a promising therapeutic target in human cancers. | Ruoxin Zhang Dakui Luo Zezhi Shan Yufei Yang Yi Qin Qingguo Li Xinxiang Li | 2023 | Acta Biochimica et Biophysica Sinica2023,55,4: | 0 |
| 6 | circCAPRIN1 interacts with STAT2 to promote tumor progression and lipid synthesis via upregulating ACC1 expression in colorectal cancer显示文摘Background:Circular RNAs(circRNAs)generated by back-splicing of precursor mRNAs(pre-mRNAs)are often aberrantly expressed in cancer cells.Accumulating evidence has revealed that circRNAs play a critical role in the progression of several cancers,including colorectal cancer(CRC).However,the current understandings of the emerging functions of circRNAs in CRC lipid metabolism and the underlying molecular mechanisms are still limited.Here,we aimed to explore the role of circCAPRIN1 in regulating CRC lipid metabolism and tumorigenesis.Methods:circRNA microarray was performed with three pairs of tumor and non-tumor tissues from CRC patients.The expression of circRNAs were determined by quantitative PCR(qPCR)and in situ hybridization(ISH).The endogenous levels of circRNAs in CRC cells were manipulated by transfection with lentiviruses overexpressing or silencing circRNAs.The regulatory roles of circRNAs in the occurrence of CRC were investigated both in vitro and in vivo using gene expression array,RNA pull-down/mass spectrometry,RNA immunoprecipitation assay,luciferase reporter assay,chromatin immunoprecipitation analysis,and fluorescence in situ hybridization(FISH).Results:Among circRNAs,circCAPRIN1 was most significantly upregulated in CRC tissue specimens.circCAPRIN1 expression was positively correlated with the clinical stage and unfavorable prognosis of CRC patients.Downregulation of circCAPRIN1 suppressed proliferation,migration,and epithelial-mesenchymal transition of CRC cells,while circCAPRIN1 overexpression had opposite effects.RNA sequencing and gene ontology analysis indicated that circCAPRIN1 upregulated the expressions of genes involved in CRC lipid metabolism.Moreover,circCAPRIN1 promoted lipid synthesis by enhancing Acetyl-CoA carboxylase 1(ACC1)expression.Further mechanistic assays demonstrated that circCAPRIN1 directly bound signal transducer and activator of transcription 2(STAT2)to activate ACC1 transcription,thus regulating lipid metabolism and facilitating CRC tumorigenesis.Conclusions:These findings revealed the oncogenic role and mechanism of circCAPRIN1 in CRC.circCAPRIN1 interacted with STAT2 to promote CRC tumor progression and lipid synthesis by enhancing the expression of ACC1.circCAPRIN1 may be considered as a novel potential diagnostic and therapeutic target for CRC patients. | Yufei Yang Dakui Luo Yang Shao Zezhi Shan Qi Liu Junyong Weng Weijing He Ruoxin Zhang Qingguo Li Ziliang Wang Xinxiang Li | 2023 | Cancer Communications2023,43,1: | 0 |
| 7 | Effectively Modulating Oxygen Vacancies in Flower‑Likeδ‑MnO_(2)Nanostructures for Large Capacity and High‑Rate Zinc‑Ion Storage显示文摘In recent years,manganese-based oxides as an advanced class of cathode materials for zinc-ion batteries(ZIBs)have attracted a great deal of attentions from numerous researchers.However,their slow reaction kinetics,limited active sites and poor electrical conductivity inevitably give rise to the severe performance degradation.To solve these problems,herein,we introduce abundant oxygen vacancies into the flower-likeδ-MnO_(2)nanostructure and effectively modulate the vacancy defects to reach the optimal level(δ-MnO_(2)-x-2.0).The smart design intrinsically tunes the electronic structure,guarantees ion chemisorption-desorption equilibrium and increases the electroactive sites,which not only effectively accelerates charge transfer rate during reaction processes,but also endows more redox reactions,as verified by first-principle calculations.These merits can help the fabricatedδ-MnO_(2)-x-2.0 cathode to present a large specific capacity of 551.8 mAh g^(-1) at 0.5 A g^(-1),high-rate capability of 262.2 mAh g^(-1) at 10 A g^(-1) and an excellent cycle lifespan(83%of capacity retention after 1500 cycles),which is far superior to those of the other metal compound cathodes.In addition,the charge/discharge mechanism of theδ-MnO_(2)-x-2.0 cathode has also been elaborated through ex situ techniques.This work opens up a new pathway for constructing the next-generation high-performance ZIBs cathode materials. | Yiwei Wang Yuxiao Zhang Ge Gao Yawen Fan Ruoxin Wang Jie Feng Lina Yang Alan Meng Jian Zhao Zhenjiang Li | 2023 | Nano-Micro Letters2023,15,12: | 0 |
