| 1 | CXCL5/CXCR2 axis in tumor microenvironment as potential diagnostic biomarker and therapeutic target显示文摘The components of the tumor microenvironment(TME)in solid tumors,especially chemokines,are currently attracting much attention from scientists.C-X-C motif chemokine ligand 5(CXCL5)is one of the important chemokines in TME.Over-expression of CXCL5 is closely related to the survival time,recurrence and metasta-sis of cancer patients.In TME,CXCL5 binds to its receptors,such as C-X-C motif chemokine receptor 2(CXCR2),to participate in the recruitment of immune cells and promote angiogenesis,tumor growth,and metastasis.The CXCL5/CXCR2 axis can act as a bridge between tumor cells and host cells in TME.Blocking the trans-mission of CXCL5/CXCR2 signals can increase the sensitivity and effectiveness of immunotherapy and slow down tumor progression.CXCL5 and CXCR2 are also regarded as biomarkers for predicting prognosis and molecular targets for customiz-ing the treatment.In this review,we summarized the current literature regarding the biological functions and clinical significance of CXCL5/CXCR2 axis in TME.The possibility to use CXCL5 and CXCR2 as potential prognostic biomarkers and thera-peutic targets in cancer is also discussed. | Wen Zhang Huishan Wang Mingyang Sun Xueting Deng Xueru Wu Yilan Ma Mengjing Li Said Maisam Shuoa Qiang You Lin Miao | 2020 | Cancer Communications2020，40，2： | 19 |
| 2 | Efficient Fe(Ⅲ)/Fe(Ⅱ) cycling triggered by MoO2 in Fenton reaction for the degradation of dye molecules and the reduction of Cr(Ⅵ)显示文摘There is a relatively low efficiency of Fe(Ⅲ)/Fe(Ⅱ) conversion cycle and H2 O2 decomposition(<30%) in conventional Fenton process,which further results in a low production efficiency of ·OH and seriously restricts the application of Fenton.Herein,we report that the commercial MoO2 can be used as the cocatalyst in Fenton process to dramatically accelerate the oxidation of Lissamine rhodamine B(L-RhB),where the efficiency of Fe(Ⅲ)/Fe(Ⅱ) cycling is greatly enhanced in the Fenton reaction meanwhile.And the L-RhB solution could be degraded nearly 100% in 1 min in the MoO2 cocatalytic Fenton system under the optimal reaction condition,which is apparently better than that of the conventional Fenton system(~50%).Different from the conventional Fenton reaction where the ’OH plays an important role in the oxidation process,it shows that 1 O2 contributes most in the MoO2 cocatalytic Fenton reaction.However,it is found that the exposed Mo^4+ active sites on the surface of MoO2 powders can greatly promote the rate-limiting step of Fe^3+/Fe^2+ cycle conversion,thus minimizing the dosage of H2 O2(0.400 mmol/L) and Fe^2+(0.105 mmol/L).Interestingly,the MoO2 cocatalytic Fenton system also exhibits a good ability for reducing Cr(Ⅵ) ions,where the reduction ability for Cr(Ⅵ) reaches almost 100% within 2 h.In short,this work shows a new discovery for M002 cocatalytic advanced oxidation processes(AOPs),which devotes a lot to the practical water remediation application. | Bin Shen Chencheng Dong Jiahui Ji Mingyang Xing Jinlong Zhang | 2019 | Chinese Chemical Letters2019，30，12： | 11 |
| 3 | Side Effects during Treatment of Advanced Gastric Carcinoma by Chemotherapy Combined with CIK-cell Transfusion in Elderly People显示文摘OBJECTIVE To study the side effects and therapeutic results of autologous cytokine-induced killer(CIK)cell treatment in elderly patients with advanced gastric cancer. METHODS CIK cells were induced and cultured using biotechnics in vitro,and then the cells were infused back into the patients.Sixty elderly gastric cancer patients treated by chemotherapy(FOLFOX4 protocol)were followed-up.Among them,29 patients were treated with CIK cells during application of chemotherapy.Short-term curative effects and adverse events from the CIK transfusion and chemotherapy were observed. RESULTS Eight cases developed partial remission(PR),9 cases moderate remission(MR),7 cases stable disease(SD)and 5 cases progressive disease(PD).Out of a total of 29 patients who received chemotherapy combined with autologous CIK therapy, the total remission rate(PR+MR)was 58.6%.The total remission rate following chemotherapy alone was 45.2%,including 5 PR cases,9 MR cases,7 SD cases,and 10 PD cases.There was a relatively lower rate of severe chemotherapic toxicities in the CIK- cell transfusion group.Side e?ects of autologous CIK transfusion included chills(13 cases),fever(9 cases),nausea and vomiting (1 case)and general malaise(3 cases).Side effects were treated with conventional therapy resulting in their amelioration.No patients developed shock,blood capillary leakage syndrome,or abnormalities in routine blood,urine,liver and renal function tests. CONCLUSION Adoptive immunotherapy with autologous CIK cells may decrease the clinical signs and symptoms of elderly patients who suffer from advanced gastric cancer.Adverse reactions of patients can be alleviated by conventional therapy. Autologous CIK-cell transfusion may improve endurance to chemotherapy. | Jingting Jiang Changping Wu Liangrong Shi Ning Xu Haifeng Deng Mingyang Lu Mei Ji Hbei Zhu Xueguang Zhang | 2008 | Chinese Journal of Clinical Oncology2008，5，2： | 10 |
| 4 | Terahertz metasurface zone plates with arbitrary polarizations to a fixed polarization conversion显示文摘Metasurfaces that can realize the polarization manipulation of electromagnetic waves on the sub-wavelength scale have become an emerging research field.Here,a novel strategy of combining the metasurface and Fresnel zone plate to form a metasurface zone plate is proposed to realize the conversion from nearly arbitrary polarizations to a fixed polarization.Specifically,when one polarized wave is incident on adjacent ring zones constructed by different types of meta-atoms,the transmitted waves generated by odd-numbered and even-numbered ring zones converge at the same focus and superimpose to generate a fixed polarized wave.As function demonstrations,we have designed two types of metasurface zone plates:one is a focused linear polarizer,and the other can convert nearly arbitrary polarized waves into focused circularly polarized waves.The simulated and measured results are consistent with theoretical expectations,suggesting that the proposed concept is flexible and feasible.Our work provides an alternative platform for polarization manipulation and may vigorously promote the development of polarization photonic devices. | Zhen Yue Jitao Li Jie Li Chenglong Zheng Jingyu Liu Guocui Wang Hang Xu Mingyang Chen Yating Zhang Yan Zhang Jianquan Yao | 2022 | Opto-Electronic Science2022，1，3： | 9 |

| 6 | Integrated transcriptome and proteome analysis provides insight into chilling-induced dormancy breaking in Chimonanthus praecox显示文摘Chilling has a critical role in the growth and development of perennial plants.The chilling requirement(CR)for dormancy breaking largely depends on the species.However,global warming is expected to negatively affect chilling accumulation and dormancy release in a wide range of perennial plants.Here,we used Chimonanthus praecox as a model to investigate the CR for dormancy breaking under natural and artificial conditions.We determined the minimum CR(570 chill units,CU)needed for chilling-induced dormancy breaking and analyzed the transcriptomes and proteomes of flowering and non-flowering flower buds(FBs,anther and ovary differentiation completed)with different CRs.The concentrations of ABA and GA3 in the FBs were also determined using HPLC.The results indicate that chilling induced an upregulation of ABA levels and significant downregulation of SHORT VEGETATIVE PHASE(SVP)and FLOWERING LOCUS T(FT)homologs at the transcript level in FBs when the accumulated CR reached 570 CU(IB570)compared to FBs in November(FB.Nov,CK)and nF16(non-flowering FBs after treatment at 16℃for−300 CU),which suggested that dormancy breaking of FBs could be regulated by the ABA-mediated SVP-FT module.Overexpression in Arabidopsis was used to confirm the function of candidate genes,and early flowering was induced in 35S::CpFT1 transgenic lines.Our data provide insight into the minimum CR(570 CU)needed for chilling-induced dormancy breaking and its underlying regulatory mechanism in C.praecox,which provides a new tool for the artificial regulation of flowering time and a rich gene resource for controlling chilling-induced blooming. | Zhineng Li Ning Liu Wei Zhang Chunyu Wu Yingjie Jiang Jing Ma Mingyang Li Shunzhao Sui | 2020 | Horticulture Research2020，7，1： | 6 |
| 7 | Responses of Spatial-temporal Variation of Karst Ecosystem Service Values to Landscape Pattern in Northwest of Guangxi,China显示文摘The responses of spatiotemporal variation of ecosystem service values (ESVs) to landscape pattern from 1985 to 2005 in a typical Karst area of the northwest Guangxi Zhuang Autonomous Region,China,were examined us-ing remote sensing and geographic information system techniques in this paper.The total ecosystem service values de-clined significantly from 1985 to 1990,and then increased slowly from 1990 to 2005,almost equaled to the 1985 level.The ecosystem service values tended to decline from the west to the east and from mountainous regions to peak-cluster depression areas in 1985,1990,2000 and 2005 respectively.During the period from 1985 to 2005,the ecosystem ser-vice values have increased in the middle and eastern parts of the study area.Landscape pattern indices,such as total area,largest patch index,contagion,aggregative index,effective mesh and proportion of like adjacencies,are significantly correlated with ecosystem service values.This suggests that ecosystem service values tend to increase with the growth of patch area and patch connectivity.However,there are negative correlations between ecosystem service values and landscape pattern indices,such as division index and patch richness.It indicates that ecosystem service values decrease with patch fragmentation and patch size shrinkage.The ecosystem conditions in the typical Karst area have been improved because of the control measures of rocky desertification.It is important to protect key landscape types,such as woodland,shrub and grassland,and to increase patch size and connectivity to avoid further fragmentation.Furthermore,it is necessary to reduce disturbances to ensure the growth of ecosystem service values and to facilitate the sustainable development in this region. | ZHANG Mingyang WANG Kelin LIU Huiyu ZHANG Chunhua | 2011 | Chinese Geographical Science2011，21，4： | 6 |
| 8 | Development mechanism of internal local corrosion of X80 pipeline steel显示文摘The occurrence and development mechanism of internal local corrosion has always been a controversial topic,and especially under flow conditions.In this paper,an improved high shear force loop was experimentally used,and local flow field is induced by simulating corrosion defects on the surface of X80 pipeline steel specimens.The characteristics of corrosion products deposited on the surface of specimens in CO2-saturated NACE solution were investigated by means of electrochemical impedance spectroscopy(EIS),scanning electron microscopy(SEM),X-ray diffraction(XRD),and energy dispersive spectrometry(EDS).The 3D micromorphology of the corrosion test surface after remove the corrosion scale used to measure the size of localized corrosion pit.Under the influence of local defects,the wall shear stress(WSS)and turbulent kinetic energy of local flow fields enhanced significantly,and pressure fluctuations in local flow field were induced.The results showed that the characteristics of surface corrosion products varied with flow velocity.The corrosion scales formed in various regions of specimens with defects exhibited different surface micro-morphologies and chemical compositions.Overall,these data offer new perspectives for better understanding the mechanisms behind local corrosion. | Zhuowei Tan Liuyang Yang Dalei Zhang Zhenbo Wang Frank Cheng Mingyang Zhang Youhai Jin | 2020 | Journal of Materials Science & Technology2020，47，14： | 6 |
| 9 | Research and development on transonic compressor of high pressure ratio turbocharger for vehicle internal combustion engines显示文摘The pressure ratio required for a turbocharger centrifugal compressor increases with internal combustion engine power density. High pressure ratio causes a transonic flow field at the impeller inducer. Transonic flow narrows the stable flow range and de-teriorates stage efficiency. In this work, an advanced high pressure ratio transonic compressor was designed. The experimental results show that the maximum pressure ratio of this turbocharger is about 4.2, the maximum efficiency is above 80% and the stable flow range at the designed rotating speed is up to 34%. A turbocharger with this transonic compressor has been applied to some vehicle research actually, and improved power density by 40%. | ZHENG XinQian, ZHANG YangJun & YANG MingYang State Key Laboratory of Automotive Safety and Energy, Tsinghua University, Beijing 100084, China | 2010 | Science China(Technological Sciences)2010，53，7： | 6 |
| 10 | Research progress of photocatalysis based on highly dispersed titanium in mesoporous SiO_2显示文摘With the development of the human economy and green chemistry, people pay much more attention to environmental safety. Correspondingly, mesoporous TiO_2 and its correlated photocatalysts are able to help people seek for better life. In this review, first of all, we briefly introduce the preparations and applications of mesoporous TiO_2-SiO_2 materials, which exhibit excellent performance in pollutants decomposition and H_2 evolution in photocatalysis. Then, we review the mesoporous composites of TiSiO_2 materials, which are ideal materials used in the photoreduction of air pollutants such as CO_2, NO and NO_2. It is powerfully evident from the literature surveys that these TiO_2 based mesoporous photocatalysts possess a large potential in environment and energy development. | Chencheng Dong Jiahui Ji Zhe Yang Yifei Xiao Mingyang Xing Jinlong Zhang | 2019 | Chinese Chemical Letters2019，30，4： | 5 |
| 11 | Microstructure Control of Non-quenched and Tempered CT80Grade Coiled Tubing Steel显示文摘Complex working condition of coiled tube(CT) steel demands high strength and low ratio of yield strength(YS) to tensile strength(TS). Reasonable microstructure control is a key problem of CT steel. Controlled rolling and controlled cooling experiments were carried out by two kinds of tested steels with different chemical compositions to develop the non-quenched and tempered CT80 steel. Mechanical properties of the tested steels at different processes are all in good agreement with the properties requirement of CT80. Increasing of Mo and Nb contents improves transformation of acicular ferrite and martensite–austenite(M–A) islands. 4 vol% of fine M/A islands increase TS and decreases ratio of YS/TS. Cooling rate increasing also improves acicular ferrite transformation and enhances TS, but has little effect on ratio of YS/TS. To meet the requirement of high strength and low ratio of YS/TS, optimized complex microstructure of the CT80 steel is composed of acicular ferrite, about 30 vol% of bainite and 4 vol% of M–A islands. | Leyu Zhou Bo Jiang Mingyang Li Fuchun Yuan Chaolei Zhang Yazheng Liu | 2014 | Acta Metallurgica Sinica(English Letters)2014，27，3： | 5 |
| 12 | PDCD5 regulates iNKT cell terminal maturation and iNKT1 fate decision显示文摘Invariant natural killer T1(iNKT1)cells are characterized by the preferential expression of T-box transcription factor T-bet(encoded by Tbx21)and the production of cytokine IFN-γ,but the relationship between the developmental process and iNKT1 lineage diversification in the thymus remains elusive.We report in the present study a crucial role of programmed cell death 5(PDCD5)in iNKT cell terminal maturation and iNKT1 fate determination.Mice with T cell-specific deletion of PDCD5 had decreased numbers of thymic and peripheral iNKT cells with a predominantly immature phenotype and defects in response toα-galactosylceramide.Loss of PDCD5 also selectively abolished the iNKT1 lineage by reducing T-bet expression in iNKT cells at an early thymic developmental stage(before CD44 upregulation).We further demonstrated that TOX2,one of the high mobility group proteins that was highly expressed in iNKT cells at stage 1 and could be stabilized by PDCD5,promoted the permissive histone H3K4me3 modification in the promoter region of Tbx21.These data indicate a pivotal and unique role of PDCD5/TOX2 in iNKT1 lineage determination.They also suggest that the fate of iNKT1 may be programmed at the developmental stage of iNKT cells in the thymus. | Ke Wang Xinwei Zhang Yifan Wang Gaowen Jin Mingyang Li Shusong Zhang Jie Hao Rong Jin Xiaojun Huang Hounan Wu Jun Zhang Yingyu Chen Qing Ge | 2019 | Cellular & Molecular Immunology2019，16，9： | 4 |

| 14 | Effect of Sanhuangyilong decoction plus methotrexate on tumor necrosis factor alpha and interferon gamma in serum and synovial fluid in rheumatoid arthritis patients with symptom pattern of damp heat obstruction显示文摘OBJECTIVE: To investigate the effect of Sanhuangyilong decoction plus methotrexate(MTX) on Interferon gamma(IFN-γ) and tumor necrosis factor alpha(TNF-α) in the serum and synovial fluid of rheumatoid arthritis(RA) patients with damp-heat-obstruction symptom pattern, Sanhuangyilong decoction and the role of TNF-α and IFN-γ in the development of RA.METHODS: RA inpatients with damp-heat-obstruction symptom pattern(partly with knee joint effusion) were selected as the research subjects. Before the treatment, healthy subjects and osteoarthritis(OA) patients with knee joint effusion were assigned to the serum control group and the synovial fluid control group, respectively; during the treatment, RA patients with damp-heat-obstruction symptom pattern were divided into two groups:one is combined group that was administered Sanhuangyilong decoction plus MTX; the other group was MTX group that received MTX only. The expression levels of TNF-α and IFN-γ in the serum and synovial fluid were measured with enzyme-linked immunosorbent assay(ELISA) before and after the treatment, and the peripheral blood levels of erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) and disease activity score in 28 joints(DAS28)were determined.RESULTS: Before treatment, the serum levels of TNF-α and IFN-γ in the RA patients with dampheat-obstruction symptom pattern were higher than those in healthy control group(P < 0.05).The expression levels of TNF-α and IFN-γ in the synovial fluid of the RA patients were higher than those in the serum of the RA patients(P < 0.05). The expression levels of TNF-α and IFN-γ in the synovial fluid of the RA patients were higher than those of the sy-novial fluid of the osteoarthritis patients(P < 0.05).The expression of TNF-α and IFN-γ in the serum and synovial fluid of the RA patients had no correlation with the inflammatory activity index ESR, CRP,or DAS28(P > 0.05). After 2 weeks of treatment, the expression level of TNF-α and IFN-γ in the combined group had increased, although the difference was not statistically significant(P > 0.05); in contrast, ESR, CRP, and DAS28 decreased, and the difference was statistically significant(P < 0.01). After 4 weeks of therapy, TNF-alpha and IFN-γ, ESR,CRP, and DAS28 in the combined group decreased compared with the before-treatment levels(P <0.01). After 2 w of treatment, the differences in the TNF-α and IFN-γ expression levels in the combined group were not statistically significant(P > 0.05)compared with that in the MTX group, although there were statistically significant differences in the ESR, CRP, and DAS28(P < 0.05). After 4 weeks of treatment, differences in TNF-α, IFN-γ, ESR, CRP, and DAS28 in the combined group compared with MTX group were statistically significant(P < 0.01).CONCLUSION: TNF-α and IFN-γ might be involved in the development of RA. The RA patients with damp-heat-obstruction symptom pattern show better benefits from the treatment of Sanhuangyilong decoction plus MTX, and the treatment is superior to that of using MTX only. | Liu Defang Yan Jiao Yun Mingdong Yang Ming Luo Yong Zhang Jun Guo Mingyang Yang Mei Yuan Weili Zou Wei Li Hua Hu Yonghe | 2016 | Journal of Traditional Chinese Medicine2016，36，5： | 4 |
| 15 | A wave of Foxp3^(+) regulatory T cell accumulation in the neonatal liver plays unique roles in maintaining self-tolerance显示文摘Newborn animals require tightly regulated local and systemic immune environments to govern the development and maturation of multiple organs/tissues even though the immune system itself is far from mature during the neonatal period.Regulatory T cells(Tregs)are essential for maintaining immune tolerance/homeostasis and modulating inflammatory responses.The features of Tregs in the neonatal liver under steady-state conditions are not well understood.The present study aimed to investigate the phenotype,functions,and significance of neonatal Tregs in the liver.We found a wave of thymus-derived Treg influx into the liver during 1–2 weeks of age.Depletion of these Tregs between days 7 and 11 after birth rapidly resulted in Th1-type liver inflammation and metabolic disorder.More Tregs in the neonatal liver than in the spleen underwent MHC II-dependent activation and proliferation,and the liver Tregs acquired stronger suppressive functions.The transcriptomic profile of these neonatal liver Tregs showed elevated expression of PPARγand T-bet and features of Tregs that utilize lipid metabolic machinery and are capable of regulating Th1 responses.The accumulation of Tregs with unique features in the neonatal liver is critical to ensure self-tolerance and liver maturation. | Mingyang Li Weijia Zhao Yifan Wang Lixue Jin Gaowen Jin Xiuyuan Sun Wei Wang Ke Wang Xi Xu Jie Hao Rong Jin Wenxian Fu Ying Sun Yingjun Chang Xiaojun Huang Xuyu Zhou Hounan Wu Kunshan Zhang Qing Ge | 2020 | Cellular & Molecular Immunology2020，17，5： | 4 |
| 16 | Hybrid Precoder and Combiner Design with Finite Resolution PSs for mmWave MIMO Systems显示文摘Hybrid precoding and combining have been considered as a promising technology, which can provide a compromise between hardware complexity and system performance in millimeter wave multiple-input multiple-output systems. However, most existing hybrid precoder and combiner designs generally assume that infinite resolution phase shifters(PSs) are used to produce the analog beamformers. In a practical scene, the design with accurate PSs can lead to high hardware cost and power consumption. In this paper, we investigate the hybrid precoder and combiner design with finite resolution PSs in millimeter wave systems. We employ alternate optimization as the main strategy to jointly design analog precoder and combiner. In addition, we propose a low complexity algorithm, where the analog beamformers are implemented only by finite resolution PSs to maximize spectral efficiency. Then, the digital precoder and combiner are designed based on the obtained analog beamformers to improve the spectral efficiency. Finally, simulation results and mathematical analysis show that the proposed algorithm with low-resolution PSs can achieve near-optimal performance and have low complexity. | Ran Zhang Weixia Zou Ye Wang Mingyang Cui | 2019 | China Communications2019，16，2： | 3 |
| 17 | Amorphous and humidity caking: A review显示文摘Caking of products is a common and undesired phenomenon in food, chemical, pharmaceutical, and fertilizer industries which leads to extra cost and irregular quality. In general, caking processes could be identified as amorphous caking or humidity caking. In this review, history of studying caking, formation, methods, and prospects of these two caking processes are summarized and discussed. The relevant studies from the 1920 s to today are mentioned briefly. According to the different properties(i.e. hygrocapacity, hygrosensitivity, mechanical properties, and diffusion behavior) of amorphous powders and crystals, the conditions and mechanisms of amorphous and humidity caking are discussed. It is summarized that glass transition, moisture sorption, quantitative methods characterizing caking, accelerated caking tests, and simulation of caking behaviors are the main aspects that should be studied for a caking process. The methods for these five aspects are reviewed. Potential research points are proposed including caking of mixed particles, caking with phase transition or polymorph transition,non-homogenous caking, and simulation of caking. | Mingyang Chen Dejiang Zhang Weibing Dong Zhilong Luo Chao Kang Haichao Li Gang Wang Junbo Gong | 2019 | Chinese Journal of Chemical Engineering2019，27，6： | 3 |
| 18 | Virtual Speed Sensorless Desired Control Strategy of Maglev Single-sided Linear Induction Motors显示文摘单边短初级长次级直线感应电机己普遍应用于低速磁悬浮的驱动系统。由于在动态纵向边端效应影响下等效电路不对称,单边直线感应电机(single-sided linear inductionmotor,SLIM)的一些参数非线性变化。传统的应用于旋转电机的无速度传感器方法不再适用。首先分析了SLIM的M/T轴等效电路,选择次级磁链作为速度观测器状态变量。根据李雅普诺夫系统稳定性判据,推导出适用于SLIM的无速度传感器辨识;然后,采用反馈广义积分观测器控制稳态辨识速度的双幅脉振幅值;引入虚拟期望变量(virtualdesiredvariable,VDV)法,利用估算速度参与SLIM的恒滑差频率矢量控制。仿真与实验对所提控制算法的有效性和实用性进行了验证,所得结论可为磁悬浮的无速度传感器控制提供参考。 | DENG Jiangming CHEN Tefang TANG Jianxiang ZHANG Guixin YU Mingyang | 2012 | 中国电机工程学报2012，32，27： | 3 |
| 19 | TiN Paper for Ultrafast-Charging Supercapacitors显示文摘Ultrafast-charging energy storage devices are attractive for powering personal electronics and electric vehicles.Most ultrafast-charging devices are made of carbonaceous materials such as chemically converted graphene and carbon nanotubes.Yet,their relatively low electrical conductivity may restrict their performance at ultrahigh charging rate.Here,we report the fabrication of a porous titanium nitride(TiN)paper as an alternative electrode material for ultrafast-charging devices.The TiN paper shows an excellent conductivity of 3.67×104 S m−1,which is considerably higher than most carbon-based electrodes.The paper-like structure also contains a combination of large pores between interconnected nanobelts and mesopores within the nanobelts.This unique electrode enables fast charging by simultaneously providing efficient ion diffusion and electron transport.The supercapacitors(SCs)made of TiN paper enable charging/discharging at an ultrahigh scan rate of 100 V s−1 in a wide voltage window of 1.5 V in Na2SO4 neutral electrolyte.It has an outstanding response time with a characteristic time constant of 4 ms.Significantly,the TiN paper-based SCs also show zero capacitance loss after 200,000 cycles,which is much better than the stability performance reported for other metal nitride SCs.Furthermore,the device shows great promise in scalability.The filtration method enables good control of the thickness and mass loading of TiN electrodes and devices. | Bin Yao Mingyang Li Jing Zhang Lei Zhang Yu Song Wang Xiao Andrea Cruz Yexiang Tong Yat Li | 2020 | Nano-Micro Letters2020，12，1： | 3 |
| 20 | Separation and recovery of associated rare earths from the Zhijin phosphorite using hydrochloric acid显示文摘The separation and extraction of associated rare earths from the Zhijin phosphorite mine is of great interest. Based on previous studies, the hydrolysis of phosphate ore using hydrochloric acid was systematically studied through extensive testing. Experiments were conducted to separate and recover the rare earths from the hydrolysis solution. Kinetic studies on the acidolysis of phosphorite using hydrochloric acid show that the use of hydrochloric acid in the acidolysis of phosphorite is mainly controlled by a chemical reaction and is also a diffusion-controlled reaction. When 210 L of HCL per 100 kg of phosphorite was used at 30 ℃ for 360 min, 96.1% of the P_2 O_5 and 95.0% of the rare earths are leached from the phosphorite. After defluorination and purification, the pH of the phosphate-acid solution is adjusted to 2.1 using sodium hydroxide, and a rare earth concentrate with rare earth content of 1.76 wt%is obtained; i.e., 90.1% of the rare earths are recovered. The rare earth content is increased to more than5 wt% through multiple enrichment processes, with a total yield of 59.5%. | Dengpan Nie An Xue Mingyang Zhu Yu Zhang Jianxin Cao | 2019 | Journal of Rare Earths2019，37，4： | 3 |
