| 1 | Polydopamine and ammonium bicarbonate coated and doxorubicin loaded hollow cerium oxide nanoparticles for synergistic tumor therapy显示文摘The development of effective nanoplatforms is extremely necessary for cancer therapy.Herein,we prepared polydopamine(PDA)andammonium bicarbonate(NH4HCO3)coated and doxorubicin(Dox)loaded hollow cerium oxide(CeO2)NPs(PDAC NPs),which showedexcellent synergistic effect for photothermal therapy,chemotherapy and chemodynamic therapy.Under near infrared laser irradiation,PDA shell could absorb the incident light and convert it into heat,which could not only kill tumor cells with hyperthermia,but also trigger thedecomposition of NH4HCO3 into gaseous carbon dioxide and ammonia,leading to the destroy of PDA shell.The leakage of PDA furtheraccelerated Dox release and exposed CeO2 surface,in which Dox could enter into cell nucleus to induce chemotherapy,and CeO2 couldcatalyze cellular hydrogen peroxide into hydroxyl radical to present chemodynamic therapy.In fact,PDAC NPs showed an excellenttherapeutic efficacy both in vitro and in vivo.This design provides a new strategy for synergistic tumor therapy. | Keqiang Xu Yan Cheng Jiao Yan Yanlin Feng Runxiao Zheng Xiaqhig Wu Yanjing Wang Panpan Song Haiyuan Zhang | 2019 | Nano Research2019，12，12： | 4 |
| 2 | Flexible lead-free BFO-based dielectric capacitor with large energy density,superior thermal stability,and reliable bending endurance显示文摘As an essential energy-stored device,the inorganic dielectric film capacitor plays an irreplaceable role in high-energy pulse power technology area.In this work,propelled by the challenge of overcoming the bottlenecks of inflexibility and inferior energy storage density of the pure BiFeO3 films,the mica with high bendability and thermal stability is adopted as substrate,and the relaxor ferroelectric(Sr_(0.7)Bi_(0.2))TiO_(3) is introduced to form solid solution to introduce relaxor behavior.The subsequently fabricated 0.3Bi(Fe_(0.95)Mn_(0.05))O_(3)-0.7(Sr_(0.7)Bi_(0.2))TiO_(3)(BFMO-SBT)thin film capacitor exhibits a high recoverable energy storage density(W_(rec)=61 J cm^(-3))and a high efficiency(η=75%)combined with a fast discharging rate(23.5 μs)due to the large polarization difference(ΔP=59.4 μC cm^(-2)),high breakdown strength(E_(b)=3000 kV cm^(-1)),and the strong relaxor dispersion(γ=1.78).Of particular importance is the capacitor presents excellent stability of energy storage performance,including a wide working temperature window of -50-200℃,fatigue endurance of 108 cycles,and frequency range of 500 Hz-20 kHz.Furthermore,there are no obviously deteriorations on energy storage capability under various bending states and after 104 times of mechanical bending cycles.All these results indicate that BFMO-SBT on mica film capacitor has potential application in the future flexible electronics. | Changhong Yang Jin Qian Panpan Lv Haitao Wu Xiujuan Lin Kun Wang Jun Ouyang Shifeng Huang Xin Cheng Zhenxiang Cheng | 2020 | Journal of Materiomics2020，6，1： | 4 |
| 3 | Mendelian randomization studies on atherosclerotic cardiovascular disease: evidence and limitations显示文摘Epidemiological research has revealed a galaxy of biomarkers, such as genes, molecules or traits, which are associated with increased risk of atherosclerotic cardiovascular diseases(ASCVD). However, the etiological basis remains poorly characterized.Mendelian randomization(MR) involves the use of observational genetic data to ascertain the roles of disease-associated risk factors and, in particular, differentiate those reflecting the presence or severity of a disease from those contributing causally to a disease. Over the past decade, MR has evolved into a fruitful approach to clarifying the causal relation of a biomarker with ASCVD and to verifying potential therapeutic targets for ASCVD. In this review, we selected high-quality MR studies on ASCVD, examined the causal relationship of a series of biomarkers with ASCVD, and elucidated the role of MR in validating biomarkers as a therapeutic target by comparing the results from MR studies and randomized clinical trials(RCTs) for the treatment of ASCVD. The good agreement between the results derived by MR and RCTs suggests that MR could be performed as a screening process before novel drug development. However, when designing and interpreting a MR study, the assumptions and limitations inherent in this approach should be taken into account. Novel methodological developments, such as sensitivity analysis, will help to strengthen the validity of MR studies. | Qin Hu Panpan Hao Qiji Liu Mei Dong Yaoqin Gong Cheng Zhang Yun Zhang | 2019 | Science China(Life Sciences)2019，62，6： | 4 |
| 4 | Fe atoms anchored on defective nitrogen doped hollow carbon spheres as efficient electrocatalysts for oxygen reduction reaction显示文摘Defective electrocatalysts,especially for intrinsic defective carbon,have aroused a wide concern owing to high spin and charge densities.However,the designated nitrogen species favorable for creating defects by the removal of nitrogen,and the influence of defects for the coordination structure of active site and oxygen reduction reaction(ORR)activity have not been elucidated.Herein,we designed and synthesized a pair of electrocatalysts,denoted as Fe-N/C and Fe-ND/C for coordination sites of atomic iron-nitrogen and iron-nitrogen/defect configuration embedded in hollow carbon spheres,respectively,through direct pyrolysis of their corresponding hollow carbon spheres adsorbed with Fe(acac)3.The nitrogen defects were fabricated via the evaporation of pyrrolic-N on nitrogen doped hollow carbon spheres.Results of comparative experiments between Fe-N/C and Fe-ND/C reveal that Fe-ND/C shows superior ORR activity with an onset potential of 30 mV higher than that of Fe-N/C.Fe-ND sites are more favorable for the enhancement of ORR activity.Density functional theory(DFT)calculation demonstrates that Fe-ND/C with proposed coordination structure of FeN_(4-x)(0 | Panpan Su Wenjuan Huang Jiangwei Zhang Utsab Guharoy Qinggang Du Qiao Sun Qike Jiang Yi Cheng Jie Yang Xiaoli Zhang Yongsheng Liu San Ping Jiang Jian Liu | 2021 | Nano Research2021，14，4： | 2 |
| 5 | A Multi-Stage Green Barrier Strategy for the Control of Global SARS-CoV-2 Transmission via Cold Chain Goods显示文摘1.The object-to-human transmission route of SARS-CoV-2 At the time of writing,coronavirus disease 2019(COVID-19),which is caused by the severe acute respiratory syndrome coron-avirus 2(SARS-CoV-2),has been a global pandemic for more than a year.As of 22 September 2021,the global cumulative incidence exceeds 229 million cases,and the number of deaths has exceeded 4.75 million[1].The current situation of epidemic prevention and control within the countries around the world can be roughly divided into two stages:the pandemic stage that the United States,the United Kingdom,and India are still experiencing(as of 23 September 2021,newly reported cases in the last 24 h in the United States,United Kingdom,and India are 202840,31095,and 26964,respectively[1]);and the normalized epidemic pre-vention and control stage that countries such as China and New Zealand are currently in. | Xu He Xinwang Liu Pan Li Panpan Wang Haijun Cheng Wenqian Li Boda Li Ting Liu Jun Ma | 2022 | Engineering2022，8，2： | 2 |
| 6 | Flexible transparent wood enabled by epoxy resin and ethylene glycol diglycidyl ether显示文摘Transparent wood has potential application in intelligent building,solar cell,electronics,and other advanced materials,while its single functionability hinders its further development.Flexible transparent wood(FTW)was prepared by alkaline pretreatment and bleaching treat-ment of paulownia wood followed by impregnation of epoxy resin and ethylene glycol diglycidyl ether(EDGE).The eff ect of delignifi cation degree on the optical and mechani-cal properties of FTW was studied,and the infl uence of the epoxy/EDGE ratio on the fl exibility and mechanical proper-ties of FTW was also investigated.The results showed that higher delignifi cation degree resulted in higher transmit-tance of FTW.More EDGE addition led to better fl exibility of FTW,while overmuch addition of EDGE will reduce the mechanical properties.The optimal FTW sample resulted in a high transmittance of 89%and an ultrahigh haze value of 97%with outstanding fl exibility and excellent mechanical properties.The investigation of FTW broadens the research fi eld of transparent wood,and provides great possibility for its application in fl exible wearable devices and fl exible materials. | Hangchuan Cai Zhiqi Wang Di Xie Panpan Zhao Jianping Sun Daoyu Qin Fangchao Cheng | 2021 | Journal of Forestry Research2021，32，4： | 2 |

| 8 | Fibroblast exosomal TFAP2C induced by chitosan oligosaccharides promotes peripheral axon regeneration via the miR-132-5p/CAMKK1 axis显示文摘Chitosan and its degradation product,oligosaccharides,have been shown to facilitate peripheral nerve regeneration.However,the underlying mechanisms are not well understood.In this study,we analyzed the protein expression profiles in sciatic nerves after injury using proteomics.A group of proteins related to exosome packaging and transport is up-regulated by chitosan oligosaccharides(COS),implying that exosomes are involved in COS-induced peripheral nerve regeneration.In fact,exosomes derived from fibroblasts(f-EXOs)treated with COS significantly promoted axon extension and regeneration.Exosomal protein identification and functional studies,revealed that TFAP2C is a key factor in neurite outgrowth induced by COS-f-EXOs.Furthermore,we showed that TFAP2C targets the pri-miRNA-132 gene and represses miR-132-5p expression in dorsal root ganglion neurons.Camkk1 is a downstream substrate of miR-132-5p that positively affects axon extension.In rats,miR-132-5p antagomir stimulates CAMKK1 expression and improves axon regeneration and functional recovery in sciatic nerves after injury.Our data reveal the mechanism for COS in axon regeneration,that is COS induce fibroblasts to produce TFAP2C-enriched EXOs,which are then transferred into axons to promote axon regeneration via miR-132-5p/CAMKK1.Moreover,these results show a new facet of fibroblasts in axon regeneration in peripheral nerves. | Yahong Zhao Jina Liu Sha Liu Panpan Yang Yunyun Liang Jinyu Ma Susu Mao Cheng Sun Yumin Yang | 2023 | Bioactive Materials2023，，8： | 1 |
| 9 | Efficient removal of naphthalene-2-ol from aqueous solutions by solvent extraction显示文摘Naphthalene-2-ol is a typical biologically recalcitrant pollutant in dye wastewater.Solvent extraction of naphthalene-2-ol from aqueous solutions using mixed solvents was investigated.Various extractants and diluents were evaluated,and the effects of volume ratio of extractant to diluent,initial p H,initial concentration of naphthalene-2-ol in aqueous solution,extraction time,temperature,volume ratio of organic phase to aqueous phase(O/A),stirring rate and extraction stages,on extraction efficiency were examined separately.Regeneration and reuse of the spent extractant were also investigated.Results showed that tributyl phosphate(TBP) achieved 98% extraction efficiency for naphthalene-2-ol in a single stage extraction,the highest among the 12 extractants evaluated.Extraction efficiency was optimized when cyclohexane and n-octane were used as diluents.The solvent combination of 20% TBP,20% n-octanol and 60% cyclohexane(V/V) obtained the maximum extraction efficiency for naphthalene-2-ol,99.3%,within 20 min using three cross-current extraction stages under the following extraction conditions:O/A ratio of 1:1,initial p H of 3,25°C and stirring rate of 150 r/min.Recovery of mixed solvents was achieved by using 15%(W/W) Na OH solution at an O:A ratio of 1:1 and a contact time of 15 min.The mixed solvents achieved an extraction capacity for naphthalene-2-ol stably higher than90% during five cycles after regeneration. | Jingjing Shao | 2016 | Journal of Environmental Sciences2016，28，9： | 1 |
| 10 | Cardiomyocyte-specific knockout of ADAM17 ameliorates left ventricular remodeling and function in diabetic cardiomyopathy of mice显示文摘Angiotensin-converting enzyme 2(ACE2)has proven beneficial in attenuating diabetic cardiomyopathy(DCM)but has been found to be a substrate of a disintegrin and metalloprotease protein-17(ADAM17).However,whether ADAM17 plays a role in the pathogenesis and intervention of DCM is obscure.In this study,we created cardiomyocyte-specific knockout of ADAM17(A17^(α-MHCKO))mice,and left ventricular dimension,function,pathology and molecular biology were assessed in ADAM17^(fl/fl) control,A17^(α-MHCKO) control,ADAM17^(fl/fl) diabetic and A17^(α-MHCKO) diabetic mice.Both differentiated H9c2 cells and neonatal rat cardiomyocytes(NRCMs)were used to explore the molecular mechanisms underlying the effect of ADAM17 on DCM.The results showed that protein expression and activity of ADAM17 were upregulated whereas the protein expression of ACE2 was downregulated in the myocardium of diabetic mice.Cardiomyocyte-specific knockout of ADAM17 mitigated cardiac fibrosis and cardiomyocyte apoptosis and ameliorated cardiac dysfunction in mice with DCM.Bioinformatic analyses detected a number of genes enriched in metabolic pathways,in particular the AMPK signaling pathway,expressed differentially between the hearts of A17^(α-MHCKO)and ADAM17^(fl/fl)diabetic mice.The mechanism may involve activated AMPK pathway,increased autophagosome formation and improved autophagic flux,which reduced the apoptotic response in cardiomyocytes.In addition,hypoxia-inducible factor-1α(HIF-1α)might act as an upstream mediator of upregulated ADAM17 and ADAM17 might affect AMPK signaling viaα1 A-adrenergic receptor(ADRA1A).These results indicated that ADAM17 activity and ACE2 shedding were enhanced in DCM,which was reversed by cardiomyocyte-specific ADAM17 knockout.Thus,inhibition of ADAM17 may provide a promising approach to the treatment of DCM. | Fei Xue Jing Cheng Yanping Liu Cheng Cheng Meng Zhang Wenhai Sui Wenqiang Chen Panpan Hao Yun Zhang Cheng Zhang | 2022 | Signal Transduction and Targeted Therapy2022，7，9： | 1 |
| 11 | One-dimensional nanochains consisting of magnetic core and mesoporous aluminosilicate for use as efficient nanocatalysts显示文摘Magnetic assembly at the nanoscale level brings potential possibilities in obtaining novel delicate nanostructures with unique physical, photonic or electronic properties. Interface surfactant micelle-directed assembly strategy holds great promising in fabricating ordered mesoporous materials with multifunctionality and pore parameter tunability. Combing these, herein, one-dimensional (1D) nanochains with well-aligned silica-coated magnetic particles as core and mesoporous aluminosilicate as shell are rational fabricated for the first time through magnetic field induced interface coassembly in biliquid system followed by the incorporation of Al species via in-situ chemical modification and transformation strategy. The obtained magnetic mesoporous aluminosilicate nanochains (MMAS-NCs) possess well-defined core-shell-shell sandwich nanostructure, tunable perpendicular mesopore channels in the shell (2.7–7.6 nm), high surface area (359 m^(2)·g^(-1)), abundant acidic sites, and superparamagnetism with a magnetization saturation of 13.8 emu·g^(-1). Thanks to the unique properties, the MMAS-NCs exhibit excellent performance in acting as magnetically recyclable superior solid acid catalysts and nanostirrers with high conversion of over 96.8%, selectivity of 95.0% in the deprotection reaction of benzaldehyde dimethylacetal to benzaldehyde. Moreover, MMAS-NCs exhibit an interesting pore size effect on the catalytic activity, namely, in the pore size range of 2–8 nm, the catalysts with larger pores show significantly enhanced catalytic activity due to the balanced mass transport and density of surface active sites. | Tong Zhang Qin Yue Panpan Pan Yuan Ren Xuanyu Yang Xiaowei Cheng Fahad A.Alharthi Abdulaziz A.Alghamdi Yonghui Deng | 2021 | Nano Research2021，14，11： | 0 |

| 15 | Polypyrrole-boosted photothermal energy storage in MOF-based phase change materials显示文摘Infiltrating phase change materials(PCMs)into nanoporous metal–organicframeworks(MOFs)is accepted as a cutting-edge thermal energy storageconcept.However,weak photon capture capability of pristine MOF-basedcomposite PCMs is a stumbling block in solar energy utilization.Towards thisgoal,we prepared advanced high-performance pristine MOF-based photothermalcomposite PCMs by simultaneously integrating photon absorber guest(polypyrrole[PPy])and thermal storage guest(1-octadecanol[ODA])intoan MOF host(Cr-MIL-101-NH2).The coated PPy layer on the surface ofODA@MOF not only serves as a photon harvester,but also serves as a phononenhancer.Resultantly,ODA@MOF/PPy composite PCMs exhibit intense andbroadband light absorption characteristic in the ultraviolet–visible–nearinfraredregion,and higher heat transfer ability than ODA@MOF.Importantly,the photothermal conversion and storage efficiency of ODA@MOF/PPy-6%is up to 88.3%.Additionally,our developed MOF-based photothermalcomposite PCMs also exhibit long-standing antileakage stability,energystorage stability,and photothermal conversion stability.The proposed coatingstrategy and in-depth understanding mechanism are expected to facilitate thedevelopment of high-efficiency MOF-based photothermal composite PCMs insolar energy utilization. | Panpan Liu Mengke Huang Xiao Chen Yan Gao Yang Li Cheng Dong Ge Wang | 2023 | Interdisciplinary Materials2023，2，3： | 0 |
| 16 | The role of autophagy in regulating metabolism in the tumor microenvironment显示文摘Autophagy,as a special programmed cell death,is a critical degradative process that eliminates intracellular abnormal proteins or damage organelles to balance cell energy and favor cell metabolism with autophagy-related(ATG)proteins.Autophagy activation is being increasingly recognized as an essential hallmark in tumorigenesis through influencing the metabolism of stromal cells in the tumor microenvironment(TME)which comprises of tumor cells,cancer-associated fibroblasts(CAFs),cancer-associated endothelial cells(CAEs),immune cells and adipocytes.Tumor cells can reuse autophagy-involved recycling to maintain mitochondrial function and energy supply to meet the metabolic demand of their growth and proliferation.However,the mechanism through which autophagy can promote a crosstalk between tumor and stroma cells is not clear.Reprogramed metabolism is one of the main characteristics of TME leading to higher adaptability of tumor cells with diverse mechanisms.The activation of autophagy has expanded our understanding on the interaction between tumor metabolism and TME.The aim of this review is to report recent advances on the metabolic cross-talk between stromal cells and solid tumor cells induced by autophagy in TME and revealed potential therapeutic targets. | Panpan Zhang Shanshan Cheng Xiaonan Sheng Huijuan Dai Kang He Yueyao Du | 2023 | Genes & Diseases2023，10，2： | 0 |
| 17 | Regulating bulkhead pressure of EPB shield machines through DEM modeling and data mining显示文摘Proper regulation of the earth pressure on the bulkhead of earth-pressure balanced(EPB)shield tunneling machines is significant to ensure safe construction.This study proposes a procedure for regulating the bulkhead pressure by combining numerical simulations and data mining,and applies the procedure to a metro line constructed in sandy pebble stratum using EPB shield.Firstly,the relationship between the bulkhead pressure and the pressure on the tunnel face is carefully obtained from discrete element modeling,and the required supporting earth pressure is derived by considering the arching effect.Secondly,aided with the machine learning method,a model is constructed for predicting the average bulkhead pressure per ring according to the operational parameters(i.e.,the average driving speed and the rotation speed of the screw conveyor).Given the target value of the bulkhead pressure,the optimal values of the operational parameters are obtained from the model.In addition,an autoregressive moving average stochastic process model is developed to monitor the real-time fluctuation of the bulkhead pressure and guide the actions taken in time to avoid dramatic fluctuations.The results indicate that the pressure difference between the tunnel face and the bulkhead is considerable,and the consideration of the arching effect can avoid overestimating the bulkhead pressure.A combination of the machine learning model and the stochastic process model provides a plausible performance in regulating the bulkhead pressure around the target value without dramatic fluctuation. | Panpan Cheng Fang Liu Youjun Xu Yuanhai Li | 2023 | Underground Space2023，，1： | 0 |

| 19 | Tightened1D/3Dcarbonheterostructure infiltratingphase change materials for solar-thermoelectric energy harvesting:Faster and better显示文摘Extensive use of thermal energy in daily life is ideal for reducing carbon emissions to achieve carbon neutrality;however,the effective collection of thermal energy is a major hurdle.Thermoelectric(TE)conversion technology based on the Seebeck effect and thermal energy storage technology based on phase change materials(PCMs)represent smart,feasible,and research-worthy approaches to overcome this hurdle.However,the integration of multiple thermal energy sources freely existing in the environment for storage and output of thermal and electrical energy simultaneously still remains a huge challenge.Herein,three-dimensional(3D)nanostructured metal-organic frameworks(MOFs)are in situ nucleated and grown onto carbon nanotubes(CNTs)via coordination bonding.After calcination,the prepared core-shell structural CNTs@MOFs are transformed into tightened 1D/3D carbon heterostructure loading Co nanoparticles for efficient solar-thermoelectric energy harvesting.Surprisingly,the corresponding composite PCMs show a record-breaking solar-thermal conversion efficiency of 98.1%due to the tightened carbon heterostructure and the local surface plasmon resonance effect of Co nanoparticles.Moreover,our designed all-in-one composite PCMs are also capable of creating an electrical potential of 0.5 mV based on the Seebeck effect without a TE generator.This promising approach can store thermal and electrical energy simultaneously,providing a new direction in the design of advanced all-in-one multifunctional PCMs for thermal energy storage and utilization. | Zhaodi Tang Piao Cheng Panpan Liu Yan Gao Xiao Chen Ge Wang | 2023 | Carbon Energy2023，5，6： | 0 |
| 20 | Al-modification for PS-PVD 7YSZ TBCs to improve particle erosion and thermal cycle performances显示文摘Plasma spray-physical vapor deposition(PS-PVD)as a novel process was used to prepare feather-like columnar thermal barrier coatings(TBCs).This special microstructure shows good strain tolerance and non-line-of-sight(NLOS)deposition,giving great potential application in aero-engine.However,due to serious service environment of aero-engine,particle erosion performance is a weakness for PS-PVD 7YSZ TBCs.As a solution,an Al-modification approach was proposed in this investigation.Through in-situ reaction of Al and ZrO2,anα-Al2O3 overlay can be formed on the surface of 7YSZ columnar coating.The results demonstrate that this approach can improve particle erosion resistance since hardness improvement of Al-modified TBCs.Meanwhile,as another important performance of thermal cycle,it has a better optimization with 350-cycle water-quenching,compared with the as-sprayed TBCs. | Xiaofeng ZHANG Ming LI Ao ZHANG Shuangquan GUO Jie MAO Chunming DENG Panpan WANG Changguang DENG Junli FENG Min LIU Kesong ZHOU Cheng LAI | 2022 | Journal of Advanced Ceramics2022，11，7： | 0 |
