| 2 | Modeling assessment for ammonium nitrogen recovery from wastewater by chemical precipitation显示文摘Chemical precipitation to form magnesium ammonium phosphate(MAP) is an effective technology for recovering ammonium nitrogen(NH4+-N).In the present research,we investigated the thermodynamic modeling of the PHREEQC program for NH4+-N recovery to evaluate the effect of reaction factors on MAP precipitation.The case study of NH4+-N recovery from coking wastewater was conducted to provide a comparison.Response surface methodology(RSM) was applied to assist in understanding the relative significance of reaction factors and the interactive effects of solution conditions.Thermodynamic modeling indicated that the saturation index(SI) of MAP followed a polynomial function of pH.The SI of MAP increased logarithmically with the Mg2+/NH4+ molar ratio(Mg/N) and the initial NH4+-N concentration(CN),respectively,while it decreased with an increase in Ca2+/NH4+ and CO32?/NH4+ molar ratios(Ca/N and CO32?/N),respectively.The trends for NH4+-N removal at different pH and Mg/N levels were similar to the thermodynamic modeling predictions.The RSM analysis indicated that the factors including pH,Mg/N,CN,Ca/N,(Mg/N)×(CO32?/N),(pH)2,(Mg/N)2,and(CN)2 were significant.Response surface plots were useful for understanding the interaction effects on NH4+-N recovery. | Tao Zhang Qiucheng Li Lili Ding Hongqiang Ren Ke Xu Yonggang Wu Dong Sheng | 2011 | Journal of Environmental Sciences2011，23，6： | 8 |
| 3 | All VN-graphene architecture derived self-powered wearable sensors for ultrasensitive health monitoring显示文摘The booming of wearable electronics has nourished the progress on developing multifunctional energy storage systems with versatile flexibility, which enable the continuous and steady power supply even under various deformed states. In this sense, the synergy of flexible energy and electronic devices to construct integrative wearable microsystems is meaningful but remains quite challenging by far. Herein, we devise an innovative supercapacitor/sensor integrative wearable device that is based upon our designed vanadium nitride-graphene (VN-G) architectures. Flexible quasi-solid-state VN-G supercapacitor with ultralight and binder-free features deliver a specific capacitance of^53 F·g^-1 with good cycle stability. On the other hand, VN-G derived pressure sensors fabricated throughout a spray-printing process also manifest favorably high sensitivity (40 kPa^-1 at the range of 2-10 kPa), fast response time (~130 ms), perfect skin conformability, and outstanding stability under static and dynamic pressure conditions. In tum, their complementary unity into a self-powered wearable sensor enables the precise detecti on of physiological motions ranging from pulse rate to phonetic recognition, holding promise for in-practical health monitoring applications. | Lianghao Yu Yuyang Yi Ting Yao Yingze Song Yiran Chen Qiucheng Li Zhou Xia Nan Wei Zhengnan Tian Baoqing Nie Li Zhang Zhongfan Liu Jingyu Sun | 2019 | Nano Research2019，12，2： | 4 |

| 6 | Interface-strengthened CoP nanosheet array with Co2P nanoparticles as efficient electrocatalysts for overall water splitting显示文摘Highly active and durable bifunctional electrocatalysts for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) play a pivotal role in overall water splitting. Herein, we demonstrate the construction of interface-strengthened CoP nanosheet array with Co2P nanoparticles as such an electrocatalyst through a facile hydrothermal reaction and the subsequent phosphorization process. The twodimensional (2D) nanosheets with thickness of^55 nm expose a great number of active sites. The surface chemical state indicates that the strongly coupled CoP/Co2P electrocatalysts can adsorb or generate more targeted intermediates (e.g. OH- or OOH*) for both HER/OER. As a result, the CoP/Co2P electrocatalysts exhibit small overpotentials of 68 and 256 mV to drive 10 mA cm^-2 for HER and OER, respectively, outperforming most of the recently reported Co-based electrocatalysts. Furthermore, an alkaline electrolyzer assembled by using CoP/Co2P as both cathode and anode can achieve a current density of 10 mA cm^-2 at a low voltage of 1.57 V and work continuously for over 58 h. This work provides a feasible structural design for transition metal phosphides electrocatalysts with efficient and stable overall water splitting. | Yanping Hua Qiucheng Xu Yanjie Hu Hao Jiang Chunzhong Li | 2019 | Journal of Energy Chemistry2019，28，10： | 1 |
| 7 | 3D-printed engineered bacteria-laden gelatin/sodium alginate composite hydrogels for biological detection of ionizing radiation显示文摘Nuclear safety is a global growing concern,where ionizing radiation(IR)is a major injury factor resulting in serious damage to organisms.The detection of IR is usually conducted with physical dosimeters;however,biological IR detection methods are deficient.Here,a living composite hydrogel consisting of engineered bacteria and gelatin/sodium alginate was 3D-printed for the biological detection of IR.Three strains of PrecA::egfp gene circuit-containing engineered Escherichia coli were constructed with IR-dependent fluorescence,and the DH5αstrain was finally selected due to its highest radiation response and fluorescence.Engineered bacteria were loaded in a series of gelatin/sodium alginate matrix hydrogels with different rheology,3D printability and bacterial applicability.A high-gelatin-content hydrogel containing 10%gelatin/1.25%sodium alginatewas optimal.The optimal living composite hydrogelwas 3D-printedwith the special bioink,which reported significant green fluorescence underγ-ray radiation.The living composite hydrogel provides a biological strategy for the detection of environmental ionizing radiation. | Ziyuan Chen Jintao Shen Meng Wei Wenrui Yan Qiucheng Yan Zhangyu Li Yaqiong Chen Feng Zhang Lina Du Bochuan Yuan Yiguang Jin | 2023 | Bio-Design and Manufacturing2023，6，4： | 0 |
| 8 | Verification of Glyphosate Resistance, Lepidopteran Resistance and Wide Compatibility of Male Sterile Line E1C4008S in Rice显示文摘Weeds and insect pests are two important biotic stresses resulting in yield loss in rice, and wide compatibility is the essential characteristic of breeding inter-subspecific hybrid rice. This study focused on glyphosate resistance, lepidopteran resistance and wide compatibility as well as identification of molecular and some agronomic characteristics of transgenic male sterile line E1 C4008 S. The results indicated that glyphosate resistance gene Epsps^# and lepidopteran resistance gene Cry1 ca^# were transferred into japonica wide compatibility male sterile line 4008 S by Agrobacterium-mediated method, and four independent transformation events named E1 C4008 S-1, E1 C4008 S-2, E1 C4008 S-3 and E1 C4008 S-4 were obtained, in which E1 C4008 S-3 and E1 C4008 S-4 were of single copy insertion. The EPSPS protein contents of E1 C4008 S-3 and E1 C4008 S-4 in different organs were significantly different both in descending order of leaf > stem > root, and ranged from 300.58 to 1410.69 μg/g at the tillering stage. The glyphosate tolerable concentration(dosage) of E1 C4008 S-3 and E1 C4008 S-4 reached at least 16 g/L(54.42 kg/hm^2), and the seeds of E1 C4008 S-4 can germinate normally on the medium containing 1 g/L glyphosate. The CRY1 C protein contents of E1 C4008 S-3 and E1 C4008 S-4 in different organs were significantly different both in descending order of leaf > stem > root, and ranged from 0.62 to 2.43 μg/g at the tillering stage. The larvae mortalities of rice leaf rollers fed on leaves of E1 C4008 S-3 and E1 C4008 S-4 for 5 d were 95.35% and 97.77%, respectively, while the average mortalities of silkworms fed with protein extracts from leaves of E1 C4008 S-3 and E1 C4008 S-4 reached 94.55% and 83.64%, respectively. The results suggested that wide compatibility and evaluated agronomic traits of E1 C4008 S-4 were not significantly changed by insertion of the exogenous genes. Overall, a novel male sterile germplasm with glyphosate resistance, lepidopteran resistance and wide compatibility was verified to be developed in rice. | ZENG Qiang DENG Lihua HU Wenbin HE Xingjian MENG Qiucheng YU Jianghui LI Jinjiang WENG Lushui XIAO Guoying | 2020 | Rice science2020，27，3： | 0 |
| 9 | Cancer cell membrane-coated bacterial ghosts for highly efficient paclitaxel delivery against metastatic lung cancer显示文摘Chemotherapy is one of the major approaches for the treatment of metastatic lung cancer,although it is limited by the low tumor delivery efficacy of anticancer drugs.Bacterial therapy is emerging for cancer treatment due to its high immune stimulation effect;however,excessively generated immunogenicity will cause serious inflammatory response syndrome.Here,we prepared cancer cell membrane-coated liposomal paclitaxel-loaded bacterial ghosts(LP@BG@CCM)by layer-by-layer encapsulation for the treatment of metastatic lung cancer.The preparation processes were simple,only involving film formation,electroporation,and pore extrusion.LP@BG@CCM owned much higher 4T1 cancer cell toxicity than LP@BG due to its faster fusion with cancer cells.In the 4T1 breast cancer metastatic lung cancer mouse models,the remarkably higher lung targeting of intravenously injected LP@BG@CCM was observed with the almost normalized lung appearance,the reduced lung weight,the clear lung tissue structure,and the enhanced cancer cell apoptosis compared to its precursors.Moreover,several major immune factors were improved after administration of LP@BG@CCM,including the CD4^(+)/CD8a^(+)T cells in the spleen and the TNF-α,IFN-γ,and IL-4 in the lung.LP@BG@CCM exhibits the optimal synergistic chemo-immunotherapy,which is a promising medication for the treatment of metastatic lung cancer. | Dandan Ling Xueli Jia Ke Wang Qiucheng Yan Bochuan Yuan Lina Du Miao Li Yiguang Jin | 2024 | Acta Pharmaceutica Sinica B2024，14，1： | 0 |
| 10 | Fe-doped and sulfur-enriched Ni3S2 nanowires with enhanced reaction kinetics for boosting water oxidation显示文摘Exploring cost-effective and highly-active oxygen evolution reaction(OER)electrocatalysts is a pressing task to propel water electrolysis for green hydrogen production.Herein,we constructed a class of Fe-doped and Senriched Ni_(3)S_(2)nanowires electrocatalysts for optimizing the target intermediates adsorption to decrease the OER overpotentials at various current densities.The optimal Ni_(3)S_(2)-1.4%Fe electrocatalyst possesses the most active sites and exhibits an ultralow overpotential of 190 mV at 10 mA cm^(-2) with an excellent stability of>60 h,exceeding the majority of recently-reported Ni_(3)S_(2)-based electrocatalysts.The trivalence Fe-doping not only reduces the electron density of the Ni center,but also enables the sulfur enrichment on the Ni_(3)S_(2) surface,which greatly improves the intrinsic activity and the number of target intermediates(*OOH).A novel methanol-assisted electrochemical evaluation further reveals that the Ni_(3)S_(2)-1.4%Fe electrocatalyst demonstrates a weaker binding ability to*OH with the rapid generation of*OOH species,and thus gives a lower apparent activation energy compared with the surface sulfur reduced ones.This work provides a new perspective for regulating the adsorption of intermediates through doping strategy. | Liyue Zhang Qiucheng Xu Rukai Zhao Yanjie Hu Hao Jiang Chunzhong Li | 2022 | Green Chemical Engineering2022，3，4： | 0 |
| 11 | Magnetic-field-induced metal-insulator quantum phase transition in CaFeAsF near the quantum limit显示文摘The quantum limit, where only the lowest Landau level is occupied by electrons, can be achieved under a high magnetic field when the Landau level splitting is comparable with the Fermi energy. The rather small Fermi pockets and Fermi energy in CaFeAsF reported recently make this compound a good candidate for investigating the electrical transport near the quantum limit.Here, we report high-field experiments up to 65 T on a single-crystalline CaFeAsF, which shows a metal-insulator quantum phase transition tuned by the out-of-plane magnetic field. The obtained critical exponent zν through the finite-size scaling analysis is very close to 4/3. This transition is closely associated with the evolution of electronic states approaching the quantum limit.The resistivity behaviors as a function of field and temperature were evaluated based on Adams-Holstein theory(A-H theory).Moreover, the in-plane component of the field, which does not affect the transport behavior in the classical region, suppressed the magnetoresistance near the quantum limit. | YongHui Ma Gang Mu Tao Hu ZengWei Zhu ZhuoJun Li Wei Li QiuCheng Ji Xuan Zhang LingLing Wang XiaoMing Xie | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，12： | 0 |
| 12 | Effects of punch size, magnetic field, and magnetorheological elastomers medium on forming T-shaped thin-walled Inconel 718 tubes显示文摘This study aims at investigating the impact of using the Magnetorheological Elastomers(MREs)medium to improve the formability of T-shaped Inconel 718 tubes during the bulging process.Besides,the influence of the punch size and the intensity of the magnetic field on the branch height and wall thickness distribution of the T-shaped Inconel 718 tubes are also explored.The results showed that the parts formed by the punch with a length of 5 mm in the pressurization zone have better forming quality.The external magnetic field can promote a high branch,and by increasing the intensity of the magnetic field,the branch height was increased and then decreased.At the same time,the magnetic field reduced the amount of material accumulation between the guiding zone and the bulging zone.Besides,it promotes the material in the guiding zone to enter the bulging zone and improve the bulging ability of the T-shaped tube. | Qiucheng YANG Cheng CHENG Ali Abd EL-ATY Chunmei LIU Shenghan HU Yao QIN Tao LI Cong WU Yong XU Xunzhong GUO | 2022 | Chinese Journal of Aeronautics2022，35，1： | 0 |
| 13 | Investigate the Effect of the Magnetic Field on the Mechanical Properties of Silicone Rubber-Based Anisotropic Magnetorheological Elastomer during Curing Process显示文摘In this investigation,a new silicone rubber-based MRE material was prepared to be used as a forming medium in manufacturing thin-walled complexshaped Ni-based tubes through the bulging process.Thus,it is significant to investigate the effect of magnetic field intensity,magnetic field loading time,and angle on the mechanical properties of the prepared MRE material during the curing process.The obtained results showed that increasing the magnetic field intensity during the curing process can improve the orientation of the chain structure in the elastomer matrix effectively.However,its mechanical properties are the best under the corresponding magnetic field intensity of 321 mT.Besides,by extending the magnetic field loading time in the curing process,the orientation of the chain structure was optimized,at the same time,the mechanical properties were also improved,and the best loading time is about 20–25 min.By changing the loading angle of the magnetic field during the curing process,the mechanical properties of the MRE were improved.When the loading angle of the magnetic field is 90°,the elastomer showed the best compression mechanical properties and excellent compression reversibility.Besides,for the anisotropic MRE material,the performance with magnetic compression is always better than that without magnetic compression. | Tao Li Ali Abd El-Aty Cheng Cheng Yizhou Shen Cong Wu Qiucheng Yang Shenghan Hu Yong Xu Jie Tao Xunzhong Guo | 2020 | Journal of Renewable Materials2020，8，11： | 0 |
