| 1 | Titanium carbonitride thick coating prepared by plasma spray synthesis and its tribological properties显示文摘TiCN coating, owing to its superior wear-resistance, has been frequently applied in many fields. TiCN thick coating was first prepared by reactive plasma spraying. The phase composition, microstructure and tribological properties of the TiCN coating were investigated in this research. Experimental results show that the microstructure of the TiCN coating was quite dense, and there was also a little amount of titanium oxides within the coating. By XPS analysis, Ti-C and Ti-N bonds were detected in the coating. The TiCN coating exhibited superior wear-resistance. The failure mechanism was attributed to the ad-hesive wear, the grinding of TiCN hard-grain, as well as the coating failure by oxidation. There were more Fe, Cr, O, etc. in the failure zone, suggesting that the corrosion propagated gradually from sur-face to interior. | ZHU Lin HE JiNing YAN DianRan XIAO LiSong DONG YanChun XUE DingChuan MENG DeLiang | 2007 | Chinese Science Bulletin2007，52，13： | 6 |
| 2 | Tumor-homing peptide-based NIR-II probes for targeted spontaneous breast tumor imaging显示文摘Fluorescence imaging in the second near-infrared window(NIR-Ⅱ,1000-1700 nm)is a promising modality for real-time imaging of cancer and image-guided surgery with superior in vivo optical properties.So far,very few NIR-Ⅱfluorophores have been reported for in vivo biomedical imaging of chemically-induced spontaneous breast carcinoma.Herein,a NIR-Ⅱfluorescent probe CH1055-F3 with the nucleolin-targeted tumor-homing peptide F3 was demonstrated to prefe rentially accumulate in 4 T1 tumors.More importantly,CH1055-F3 exhibited specific NIR-Ⅱsignals with high spatial and temporal resolution,strong tumor uptake,and remarkable NIR-Ⅱimage-guided surgery in dimethylbenzanthracene(DMBA)-induced spontaneous breast tumor rats.This report presents the first tumor-homing peptide-based NIR-Ⅱprobe to diagnose transplantable and spontaneous breast tumors by the active targeting. | Hui Zhou Shanshan Li Xiaodong Zeng Mengxian Zhang Lin Tang Qianqian Li Deliang Chen Xianli Meng Xuechuan Hong | 2020 | Chinese Chemical Letters2020，31，6： | 6 |
| 3 | Fabricating antibacterial CoCrCuFeNi high-entropy alloy via selective laser melting and in-situ alloying显示文摘A quasi-equiatomic CoCrFeCuNi high-entropy alloy(HEA) with a broad-spectrum antibacterial ability and good mechanical properties has been fabricated by selective laser melting(SLM) and in-situ alloying of a blend of pre-alloyed CoCrFeNi powder and Cu elemental powder.The as-built HEA alloy has a homogeneous distribution of Cu and presents a single FCC phase.Compared with the same HEA fabricated using the traditional ingot metallurgy(IM) process,the HEA alloy fabricated by SLM releases more Cu ions to prevent growth and biofilm formation by gram-negative Escherichia coli and gram-positive Staphylococcus aureus,which enhances the applicability of the HEA alloy in potential applications that requires antibacterial ability.The results of this study confirm the feasibility of combining the antibacterial CoCrFeCuNi HEA alloy and SLM technology in fabricating complex shaped parts or structures with a strong antibacterial ability to be used in medical application or other environments desired for antibacterial ability. | Jingbo Gao Yuting Jin Yongqiang Fan Dake Xu Lei Meng Cong Wang Yuanping Yu Deliang Zhang Fuhui Wang | 2022 | Journal of Materials Science & Technology2022，，7： | 4 |
| 4 | Climate change induced eutrophication of cold-water lake in an ecologically fragile nature reserve显示文摘Aquatic ecosystem sustainability around the globe is facing crucial challenges because of increasing anthropogenic and natural disturbances. In this study, the Tianchi Lake, a typical cold-water lake and a UNESCO/MAB(Man and Biosphere) nature reserve located in high latitude and elevation with the relatively low intensity of human activity was chosen as a system to examine the linkages between climate change and eutrophication. As a part of the UNESCO Bogda Man and Biosphere Reserve, Tianchi Lake has been well preserved for prevention from human intervention, but why has it been infected with eutrophication recent years? Our results show that climate change played a significant role in the eutrophication in the Tianchi Lake. Increased temperature, changed precipitation pattern and wind-induced hydrodynamic fluctuations in the summer season were suggested to make a major contribution to the accelerated eutrophication. The results also showed that the local temperature and precipitation changes were closely linked to the large-scale atmospheric circulation, which opens the door for the method to be applied in other regions without local climatic information. This study suggests that there is an urgent need to take into consideration of climate change adaptation into the conservation and management of cold-water lakes globally. | Xiaotian Lu Yonglong Lu Deliang Chen Chao Su Shuai Song Tieyu Wang Hanqin Tian Ruoyu Liang Meng Zhang Kifayatullah Khan | 2019 | Journal of Environmental Sciences2019，31，1： | 4 |
| 5 | Preparation of La2O3 by ion-exchange membrane electrolysis of LaCl3 aqueous solution显示文摘The ion-exchange membrane electrolysis technology was applied inventively in the preparation of lanthanum hydroxide,after calcination,lanthanum oxide was obtained eventually.The effect of the concentration of lanthanum chlo ride solution on electrolytic product was mainly investigated.The phase composition,micro morphology,particle size and chlorine content of the product were characterized,respectively.Under the conditions of this work,the product that forms by electrolysis of LaCl3 aqueous solution directly is La(OH)3.When the initial concentration of LaCl3 changes from 0.1 to 0.5 mol/L,the current efficiency of La(OH)3 increases from 60%to 85%,the product roasted at 800℃for 1.5 h is La2O3,whose median particle size(D50)is 10-20μm,the mass fraction of chloride ion is less than 0.02 wt%.Additio nally,the prepared La2O3 particles are porous and non-spherical particle s,which are composed of small crystals with sheet structure. | Deliang Meng Qiuyue Zhao Xijuan Pan Ting’an Zhang | 2019 | Journal of Rare Earths2019，37，9： | 3 |
| 6 | Behavior of phase transformation of Baotou mixed rare earth concentrate during oxidation roasting显示文摘Based on the new process named 'Combination Method' for metallurgy and separation of Baotou mixed rare earth concentrate(BMREC),the aim of this paper is to clearly elucidate the phase change behavior of BMREC without additives during oxidative roasting at 450-800℃.The results indicate that the bastnaesite in BMREC is decomposed at 450-550℃,the weight loss is about 10.3 wt%,and the activation energy(E) is 144 kJ/mol.The bastnaesite in BMREC is decomposed into rare earth fluoride,rare earth oxides(La_(2)O_(3),Ce_(7)O_(12),Pr_(6)O_(11) and Nd_(2)O_(3)),and CO_(2),particularly,with the increase of roasting temperature,bastnaesite in BMREC is more completely decomposed into LaF_(3),which causes a decrease in leaching rate of La during the HCI leaching process.Additionally,the maximum cerium oxidation efficiency reaches about 60 wt% when the roasting temperature is equal to or above 500℃,and the oxidation reaction rate of cerium increases with the increasing roasting temperature. | Deliang Meng Meng Wang Zongyu Feng Chao Xia Yanyan Zhao Xiaowei Huang | 2022 | Journal of Rare Earths2022，40，6： | 3 |
| 7 | Behavior of sulfate in preparation of single light rare earth carbonate by Mg(HCO_(3))_(2) precipitation method显示文摘The precipitation of the water-leaching solution of Baotou mixed rare earth(RE) concentrate roasted with sulfuric acid using ammonium bicarbonate for producing RE carbonate produces a mass of ammonia-nitrogen wastewater because of the relatively low solubility of rare earth sulfate.To solve the serious problem of ammonia-nitrogen pollution,new precipitators need to be developed urgently so as to meet the requirements of environmental protection and impurities content of the product(SO_(4)^(2-)<1.8 wt% in RE carbonates products).In this paper,we studied the effects of feeding modes on the behavior of SO_(4)^(2-) during the preparation of light RE carbonate(RE=La,Ce,Pr,Nd) from their sulfate solutions using Mg(HCO_(3))_(2) as a precipitant.The results indicate that the contents of SO_(4)^(2-) in the La and Ce precipitates using positive feeding mode exceed 16 wt% because of the formation of La_(2)(CO_(3))2.15(-SO_(4))0.85·4 H_(2)O and Ce_(2)(CO_(3))_(2).15(SO_(4))0.85·3H_(2)O,while those of the Pr and Nd precipitates are 4 wt%-5 wt% since they exist in the form of n-carbonate.The precipitates prepared using synchronous feeding mode are all RE carbonate with only 4 wt%-5 wt% of SO_(4)^(2-) enclosed in the precipitation.The content of SO_(4)^(2-) in the RE carbonate obtained using reverse feeding mode is the lowest.Among them,the content of SO_(4)^(2-) in La precipitate is only 1.40 wt%.Both synchronous and reverse feeding modes can effectively reduce the content of SO_(4)^(2-)in RE carbonate,which provides theoretical guidance for the preparation of qualified light RE carbonate products by Mg(HCO3)2 precipitation method. | Meng Wang Xiaowei Huang Zongyu Feng Chao Xia Deliang Meng Zonghe Yu | 2021 | Journal of Rare Earths2021，39，7： | 3 |

| 15 | A General Strategy for Ordered Carrier Transport of Quasi‑2D and 3D Perovskite Films for Giant Self‑Powered Photoresponse and Ultrahigh Stability显示文摘Organic–inorganic hybrid perovskite materials have been focusing more attention in the field of self-powered photodetectors due to their superb photoelectric properties.However,a universal growth approach is required and challenging to realize vertically oriented growth and grain boundary fusion of 2D and 3D perovskite grains to promote ordered carrier transport,which determines superior photoresponse and high stability.Herein,a general thermal-pressed(TP)strategy is designed to solve the above issues,achieving uniaxial orientation and single-grain penetration along the film thickness direction.It constructs the efficient channel for ordered carrier transport between two electrodes.Combining of the improved crystal quality and lower trap-state density,the quasi-2D and 3D perovskite-based self-powered photodetector devices(with/without hole transport layer)all exhibit giant and stable photoresponse in a wide spectrum range and specific wavelength laser.For the MAPbI_(3)-based self-powered photodetectors,the largest R_(λ) value is as high as 0.57 A W^(−1)at 760 nm,which is larger than most reported results.Meanwhile,under laser illumination(532 nm),the FPEA_(2)MA_(4)Pb_(5)I_(16)-based device exhibits a high responsivity(0.4 A W^(−1)) value,which is one of the best results in 2DRP self-powered photodetectors.In addition,fast response,ultralow detection limit,and markedly improved humidity,optical and heat stabilities are clearly demonstrated for these TP-based devices. | Fei Zhu Gang Lian Deliang Cui Qilong Wang Haohai Yu Huaijin Zhang Qingbo Meng Ching‑Ping Wong | 2023 | Nano-Micro Letters2023，15，8： | 0 |

| 17 | Reaction between tetravalent cerium ion and chloride ion and effect of thiourea using cyclic voltammetry显示文摘To monitor the reaction between Ce^(4+) ion and Cl-ion at the electron level,an electrochemical experiment was designed in this work.Herein,the intermediate and final products that may be produced during the redox reaction are directly tracked by using cyclic voltammetry,and the influences of Ce^(4+) ion concentration,temperatu re and F-ion on the reduction peak potential of Ce^(4+) ion were investigated.The results show that Ce^(4+) ion reacts with Cl-ion through an irreversible reaction without any intermediate products,and the rate-determining step of the reaction is diffusion during the electrode reaction.The effects of temperature(20-40℃) and Ce^(4+) ion concentration(0.04-0.12 mol/L) on the reduction peak pote ntial of Ce^(4+) ion can be ignored,but the higher the molar ratio of F-to Ce^(4+)(0-3 mol/mol),the mo re easily the reduction of Ce^(4+) ion to Ce^(3+) ion occurs.Additionally,the Ce^(4+) ions are preferentially reduced by thiourea when thiourea is added in the HCl solution,and thiourea inhibits the oxidation of Cl-ions to Cl_(2) by forming a complex with Cl-ions.This work provides a theoretical basis for the role of thiourea in inhibiting Cl_(2) production and offers a new way to find new reductants. | Deliang Meng Xiaowei Huang Zongyu Feng Meng Wang Juanyu Yang Chao Xia Yanyan Zhao Yuqing Wei | 2022 | Journal of Rare Earths2022，40，10： | 0 |
| 18 | Effect of phase transition during roasting of Mountain Pass rare earth concentrate on leaching efficiency of rare earths显示文摘To find a greener and more economical approach for treating the Mountain Pass rare earth concentrate(MPREC),a novel 'Combination Method',including the processes of oxidizing roasting,HCI leaching and sulfuric acid roasting,is proposed in this research.In this paper,the effect of phase transition behavior in hydrochloric acid leaching during oxidative roasting at 450-600℃ was studied.During roasting,the bastnasite in MPREC is decomposed into CeLa_(2)O_(3)F_(3) and(Ce_(0.33),La_(0.33),Ca_(0.33))O_(1.5).As the CeLa_(2)O_(3)F_(3) phase has the fluorine-fixation effect,the generated CeLa_(2)O_(3)F_(3) phase can not be dissolved by HCI after roasting at 500 and 550℃,but it can be decomposed by HCI after roasting at over 600℃,resulting in the improvement of the leaching rate of total F element.The maximum leaching efficiency of rare earth elements(REEs) can reach 70.32 wt% at the roasting temperature of 550℃.After roasting at over 600℃,some F^-ions in the solution combined with RE^(3+) to form REF_(3) precipitate and enter the leaching residue,and the others are in the form of [CeF_(3)]^+ in the leaching solution during leaching,therefore,the leaching efficiency of non-ce rium REEs decreases while that of cerium element increases.This work provides basic research for optimizing the actual production process of MPREC. | Yanyan Zhao Xu Sun Deliang Meng Xiangsheng Liu Qiang Zhong Zongyu Feng | 2024 | Journal of Rare Earths2024，42，2： | 0 |
