| 1 | Enhanced pyrocatalysis of the pyroelectric BiFeO_(3)/g-C_(3)N_(4) heterostructure for dye decomposition driven by cold–hot temperature alternation显示文摘The BiFeO_(3)/g-C_(3)N_(4) heterostructure,which is fabricated via a simple mixing–calcining method,benefits the significant enhancement of the pyrocatalytic performance.With the growth of g-C_(3)N_(4) content in the heterostructure pyrocatalysts from 0 to 25%,the decomposition ratio of Rhodamine B(RhB)dye after 18 cold-hot temperature fluctuation(25-65℃)cycles increases at first and then decreases,reaching a maximum value of~94.2%at 10%while that of the pure BiFeO_(3) is~67.7%.The enhanced dye decomposition may be due to the generation of the internal electric field which strengthens the separation of the positive and negative carriers and further accelerates their migrations.The intermediate products in the pyrocatalytic reaction also have been detected and confirmed,which proves the key role of the pyroelectric effect in realizing the dye decomposition using BiFeO_(3)/g-C_(3)N_(4) heterostructure catalyst.The pyroelectric BiFeO_(3)/g-C_(3)N_(4) heterostructure shows the potential application in pyrocatalytically degrading dye wastewater. | Mingzi Chen Yanmin Jia Huamei Li Zheng Wu Tianyin Huang Hongfang Zhang | 2021 | Journal of Advanced Ceramics2021，10，2： | 6 |
| 2 | Differences of hormones involved in adipose metabolism and lactation between high and low producing Holstein cows during heat stress显示文摘The experiment was conducted to evaluate hormonal involvement in the adipose metabolism and lactation between high and low producing dairy cows in a hot environment. Forty Holstein healthy cows with a similar parity were used and assigned into high producing group(average production41.44 ± 2.25 kg/d) and low producing group(average production 29.92 ± 1.02 kg/d) with 20 cows in each group. Blood samples were collected from caudal vein to determine the difference of hormones related to adipose metabolism and lactation. The highest, lowest, and average temperature humidity index(THI),recorded as 84.02, 79.35 and 81.89, respectively, indicated that cows were at the state of high heat stress.No significant differences between high and low producing groups were observed in the levels of nonestesterified fatty acid(NEFA), β-hydroxy butyrate(β-OHB), total cholesterol(TCHO), and insulin(INS)(P > 0.05). However, the very low density lipoprotein(VLDL), apolipoprotein B100(apoB-100), highdensity lipoprotein(HDL-C) and estrogen(E2) concentrations in high producing group were significantly higher than those of low producing group(P < 0.05). No significant differences between high and low producing groups were observed in the levels of prolactin(PRL) and progesterone(PROG)(P > 0.05),whereas high producing group had a rise in the insulin-like growth factor-1(IGF-1) level compared with low producing group(P < 0.05). These results indicated that, during summer, high and low producing dairy cows have similar levels of lipid catabolism, but high producing dairy cows have advantages in outputting hepatic triglyceride(TG). | Mingzi Qu Shengjuan Wei Zhiqiang Chen Guangmeng Wang Yue Zheng Peishi Yan | 2015 | Animal Nutrition2015，，4： | 4 |
| 3 | MOF-Transformed In_(2)O_(3-x)@C Nanocorn Electrocatalyst for Efficient CO_(2)Reduction to HCOOH显示文摘For electrochemical CO_(2) reduction to HCOOH,an ongoing challenge is to design energy efficient electrocatalysts that can deliver a high HCOOH current density(JHCOOH)at a low overpotential.Indium oxide is good HCOOH production catalyst but with low con-ductivity.In this work,we report a unique corn design of In_(2)O_(3-x)@C nanocatalyst,wherein In_(2)O_(3-x)nanocube as the fine grains dispersed uniformly on the carbon nanorod cob,resulting in the enhanced conductivity.Excellent performance is achieved with 84%Faradaic efficiency(FE)and 11 mA cm^(−2)JHCOOH at a low potential of−0.4 V versus RHE.At the current density of 100 mA cm^(−2),the applied potential remained stable for more than 120 h with the FE above 90%.Density functional theory calculations reveal that the abundant oxygen vacancy in In_(2)O_(3-x) has exposed more In^(3+) sites with activated electroactivity,which facilitates the formation of HCOO*intermediate.Operando X-ray absorp-tion spectroscopy also confirms In^(3+) as the active site and the key intermediate of HCOO*during the process of CO_(2) reduction to HCOOH. | Chen Qiu Kun Qian Jun Yu Mingzi Sun Shoufu Cao Jinqiang Gao Rongxing Yu Lingzhe Fang Youwei Yao Xiaoqing Lu Tao Li Bolong Huang Shihe Yang | 2022 | Nano-Micro Letters2022，14，10： | 2 |
| 4 | Ginsenoside Rh3 induces pyroptosis and ferroptosis through the Stat3/p53/NRF2 axis in colorectal cancer cells显示文摘Ginsenoside Rh3(GRh3)is a seminatural product obtained by chemical processing after isolation from Chinese herbal medicine that has strong antitumor activity against human tumors.However,its antitumor role remains to be elucidated.The aim of this study is to explore the mechanisms underlying the tumor suppressive activity of GRh3 from the perspective of pyroptosis and ferroptosis.GRh3 eliminates colorectal cancer(CRC)cells by activating gasdermin D(GSDMD)-dependent pyroptosis and suppressing solute carrier family 7 member 11(SLC7A11),resulting in ferroptosis activation through the Stat3/p53/NRF2 axis.GRh3 suppresses nuclear factor erythroid 2-related factor 2(NRF2)entry into the nucleus,leading to the decrease of heme oxygenase 1(HO-1)expression,which in turn promotes NOD-like receptor thermal protein domain associated protein 3(NLRP3)and caspase-1 expression.Finally,caspase-1 activates GSDMD-dependent pyroptosis.Furthermore,GRh3 prevents NRF2 from entering the nucleus,which suppresses SLC7A11,causing the depletion of glutathione(GSH)and accumulation of iron,lipid reactive oxygen species(ROS)and malondialdehyde(MDA),and eventually leading to ferroptosis in CRC cells.In addition,GRh3 effectively inhibits the proliferation of CRC cells in vitro and in nude mouse models.Collectively,GRh3 triggers pyroptotic cell death and ferroptotic cell death in CRC cells via the Stat3/p53/NRF2 axis with minimal harm to normal cells,showing great anticancer potential. | Yingchao Wu Dajin Pi Shuyao Zhou Zhongjia Yi Yangyang Dong Wuhong Wang Huan Ye Yiliu Chen Qian Zuo Mingzi Ouyang | 2023 | Acta Biochimica et Biophysica Sinica2023，55，4： | 1 |
| 5 | Interface synergistic effects induced multi-mode luminescence显示文摘Mechanoluminescence(ML)has become the most promising material for broad applications in display and sensing devices,in which ZnS is the most commonly studied one due to its stable and highly repetitive ML performances.In this work,we have successfully prepared the biphase ZnS on a large scale through the facile in-air molten salt protection strategy.The obtained biphase has the best ML properties,which is mainly attributed to the synergistic effects of piezo-photonic,defect,and interface dislocations.DFT calculations have confirmed that the defects activate the local S and Zn sites and reduce the energy barrier for electron transfer.The much stronger X-ray induced luminescence than the commercial scintillator is also reached.The application of ZnS particles in both papers and inks delivers superior performance.Meanwhile,ZnS particles based screen printing ink is able to directly print on paper,plastic and other carriers to form clear marks.These proposed paper and ink hold great potentials in applications of information security and anti-counterfeiting based on the multi-mode luminescence properties.This work provides a new avenue to understand and realize the high-performance multi-mode luminescence,inspiring more future works to extend on other ML materials and boosting their practical applications. | Ronghua Ma Chunfeng Wang Wei Yan Mingzi Sun Jianxiong Zhao Yuantian Zheng Xu Li Longbiao Huang Bing Chen Feng Wang Bolong Huang Dengfeng Peng | 2022 | Nano Research2022，15，5： | 1 |
| 6 | Novel Real-Time System for Traffic Flow Classification and Prediction显示文摘Traffic flow prediction has been applied into many wireless communication applications(e.g., smart city, Internet of Things). With the development of wireless communication technologies and artificial intelligence, how to design a system for real-time traffic flow prediction and receive high accuracy of prediction are urgent problems for both researchers and equipment suppliers. This paper presents a novel real-time system for traffic flow prediction. Different from the single algorithm for traffic flow prediction, our novel system firstly utilizes dynamic time wrapping to judge whether traffic flow data has regularity,realizing traffic flow data classification. After traffic flow data classification, we respectively make use of XGBoost and wavelet transform-echo state network to predict traffic flow data according to their regularity. Moreover, in order to realize real-time classification and prediction, we apply Spark/Hadoop computing platform to process large amounts of traffic data. Numerical results show that the proposed novel system has better performance and higher accuracy than other schemes. | YE Dezhong LV Haibing GAO Yun BAO Qiuxia CHEN Mingzi | 2019 | ZTE Communications2019，17，2： | 0 |
| 7 | Chiral self-assembly of terminal alkyne and selenium clusters organic–inorganic hybrid显示文摘The on-surface self-assembly of inorganic atomic clusters and organic molecules offers significant opportunities to design novel hybrid materials with tailored functionalities.By adopting the advantages from both inorganic and organic components,the hybrid self-assembly molecules have shown great potential in future optoelectrical devices.Herein,we report the co-deposition of 4,8-diethynylbenzo[1,2-d-4,5-d0]bisoxazole(DEBBA)and Se atoms to produce a motif-adjustable organic–inorganic hybrid self-assembly system via the non-covalent interactions.By controlling the coverage of Se atoms,various chiral molecular networks containing Se,Se_(6),Se_(8),and terminal alkynes evolved on the Ag(111)surface.In particular,with the highest coverage of Se atoms,phase segregation into alternating one-dimensional chains of non-covalently bonded Se_(8) clusters and organic ligands has been noticed.The atom-coverage dependent evolution of self-assembly structures reflects the remarkable structural adaptability of Se clusters as building blocks based on the spontaneous resize to reach the maximum non-covalent interactions.This work has significantly extended the possibilities of flexible control in self-assembly nanostructures to enable more potential functions for broad applications. | Zhi Chen Tao Lin Haohan Li Mingzi Sun Chenliang Su Bolong Huang Kian Ping Loh | 2022 | Nano Research2022，15，3： | 0 |
| 8 | Engineering the synergistic effect of carbon dots-stabilized atomic and subnanometric ruthenium as highly efficient electrocatalysts for robust hydrogen evolution显示文摘Currently,the most efficient electrocatalyst for the hydrogen evolution reaction(HER)in water dissociation is Pt-based catalyst.Unfortunately,the high cost and less than perfect efficiency hinder wide-range industrial/technological applications.Here,by controlling the treatment temperature of tris(2,2-bipyridine)ruthenium dichloride hexahydrate,synthesis of compounds with novel ruthenium single/dual atoms(Ru S/DAs)mixed with Ru nanoclusters(Ru S/DAs+Ru NCs)and supported by carbon dots is demonstrated.These compounds are shown to be highly efficient and competitive catalysts for hydrogen evolution.Ru S/DAs+Ru NCs exhibit very high activity,with overpotentials of 15 and 40mV at a current density of 10mA/cm2 in 1.0mol/L KOH and 0.5mol/L H2SO4,respectively.Furthermore,the composites are found to possess outstanding stability and rapid HER kinetics.X ray absorption fine structure analysis,supported by density functional theory calculations,shows charge rearrangement in single-atomic Ru,and the Ru dual sites promote active hydrogen adsorption and recombination.Ru S/DAs and Ru NCs demonstrate high electroactivity due to the electroactive Ru 4d orbitals.The introduction of Ru NCs activates the carbon support,providing a high electronic conductivity to transfer electrons from Ru NCs to Ru S/DAs,and facilitates water dissociation for the HER process. | Yuan Liu Ning Chen Weidong Li Mingzi Sun Tong Wu Bolong Huang Xue Yong Qinghua Zhang Lin Gu Haoqiang Song Robert Bauer John S.Tse Shuang-Quan Zang Bai Yang Siyu Lu | 2022 | SmartMat2022，3，2： | 0 |
| 9 | Carboxylated carbon nanotubes with high electrocatalytic activity for oxygen evolution in acidic conditions显示文摘Since most electrocatalysts for oxygen evolution reaction(OER),except for precious metal oxides RuO_(2) and IrO_(2),are unstable in harsh acidic solutions,it is highly desirable to develop high-performance OER electrocatalysts for acidic media,though it is still a big challenge.Herein,we report a simple strategy to produce carboxyl-enriched multiwalled carbon nanotubes(COOH-MWNTs)that exhibit stable and high electrocatalytic activities for OER in acidic solutions,showing an overpotential at a current density of 10 mA cm^(–2) and a Tafel slope as low as of 265 mV and 82 mV dec^(–1),respectively.As far as we are aware,these results represent the best OER performance for metal-free electrocatalysts,even comparable to those of RuO_(2) and IrO_(2).We have further revealed the catalytic mechanism,which involves one electron lose from the COOH-MWNTs catalyst at the beginning of the OER process to trigger H_(2)O molecule oxidation by forming peralcohol,followed by the recapture of one electron from water molecule to oxidize water and to recover the initial state for the COOH-MWNTs catalyst.The unravel of this new OER mechanism is important as it provides new insights into the crucial role of organic functional groups in electrocatalytic processes.Also,the mechanistic understanding can be used to guide the design and development of novel metalfree catalysts for acidic OER electrocatalysis and beyond. | Xin Zhang Wenqing Zhang Jianying Dai Mingzi Sun Jun Zhao Lifei Ji Lin Chen Fanlong Zeng Fengchun Yang Bolong Huang Liming Dai | 2022 | InfoMat2022，4，1： | 0 |
