| 1 | Pressure fluctuation propagation of a pump turbine at pump mode under low head condition显示文摘Pressure fluctuation at the vaneless space and vanes passages is one of the most important problems for the stable operation of a pump turbine.The fluctuation appears in any operating condition.Much research has been done on the pressure fluctuation of hydraulic machinery.However,the details of pressure fluctuation propagation of the pump turbine at the pump mode have not been revealed.The modern pump turbine with high water head requires the runner to be'flat',which would induce pressure fluctuation more easily than the low head pump turbine.In this article,a high head pump turbine model is used as the research object.As the pressure fluctuation at off-design point is more serious than at the design point,the low head condition is chosen as the research condition.Pressure fluctuation at the vaneless space and vanes passages is predicted by the computational fluid dynamics method based on k-?shear stress transport model.The experiment conducted on the test rig of the Harbin Institute of Large Electrical Machinery is used to verify the simulation method.It proves that the numerical method is a feasible way to research the fluctuation under this operating condition.The pressure fluctuation along the passage direction is analyzed at time and frequency domains.It is affected mainly by the interaction between the runner and vanes.In the circumferential direction,the influence of the special stay vane on the pressure fluctuation is got.The amplitude in the high-pressure side passage of that vane is lower than that in the other side.The study provides a basic understanding of the pressure fluctuation of a pump turbine and could be used as a reference to improve the operation stability of it. | GUO Lei LIU JinTao WANG LeQin QIN DaQing WEI XianZhu | 2014 | Science China(Technological Sciences)2014，57，4： | 19 |

| 3 | Effects of Dietary Stachyose on Growth Performance, Digestive Enzyme Activities and Intestinal Morphology of Juvenile Turbot(Scophthalmus maximus L)显示文摘A 12-week feeding trial was conducted to evaluate the effects of dietary stachyose on the growth performance, digestive enzymes activities and intestinal structures of juvenile turbot(Scophthalmus maximus L). Five isonitrogenous(49.58% crude protein) and isolipidic(10.50% crude lipid) diets were formulated to contain 0(Control), 0.625%(S-0.625), 1.25%(S-1.25), 2.5%(S-2.5) and 5%(S-5) stachyose, respectively. With the increase of stachyose level, the growth performance and feed utilization of turbot, such as the specific growth rate, final mean body weight, weight gain rate and feed efficiency, increased significantly(P < 0.05) and then stabilized. The feed intake of fish fed S-5 was significantly higher(P < 0.05) than that of fish in other groups. The activities of trypsin, intestinal caseinolytic, stomach and intestinal amylase were significantly influenced by stachyose(P < 0.05). The highest values of trypsin and intestinal caseinolytic activities were observed in group S-1.25, while the highest activity of stomach amylase and the lowest activity of intestine amylase were observed in group S-5. No lesion or damage was found on the distal intestine structures of fish from all treatments, while the height of simple folds in the distal intestine was significantly increased(P< 0.05) when 1.25% or 2.5% stachyose was added in the diets. These results indicated that moderate level of stachyose(1.25%) improves the growth performance, feed utilization, digestive enzyme activities and the distal intestine structures of juvenile turbot. | HU Haibin ZHANG Yanjiao MAI Kangsen AI Qinghui XU Wei ZHANG Wenbing LI Yanxian LIU Jintao | 2015 | Journal of Ocean University of China2015，14，5： | 10 |
| 4 | Supplemental magnolol or honokiol attenuates adverse effects in broilers infected with Salmonella pullorum by modulating mucosal gene expression and the gut microbiota显示文摘Background:Salmonella pullorum is one of the most harmful pathogens to avian species.Magnolol and honokiol,natural compounds extracted from Magnolia officinalis,exerts anti-inflammatory,anti-oxidant and antibacterial activities.This study was conducted to evaluate the effects of dietary supplemental magnolol and honokiol in broilers infected with S.pullorum.A total of 360 one-day-old broilers were selected and randomly divided into four groups with six replicates:the negative control group(CTL),S.pullorum-infected group(SP),and the S.pulloruminfected group supplemented with 300 mg/kg honokiol(SPH)or magnolol(SPM).Results:The results showed that challenging with S.pullorum impaired growth performance in broilers,as indicated by the observed decreases in body weight(P<0.05)and average daily gains(P<0.05),along with increased spleen(P<0.01)and bursa of Fabricus weights(P<0.05),serum globulin contents,and the decreased intestine villus height and villus/crypt ratios(P<0.05).Notably,supplemental magnolol and honokiol attenuated these adverse changes,and the effects of magnolol were better than those of honokiol.Therefore,we performed RNA-Seq in ileum tissues and 16S rRNA gene sequencing of ileum bacteria.Our analysis revealed that magnolol increased the α-diversity(observed species,Chao1,ACE,and PD whole tree)and β-diversity of the ileum bacteria(P<0.05).In addition,magnolol supplementation increased the abundance of Lactobacillus(P<0.01)and decreased unidentified Cyanobacteria(P<0.05)both at d 14 and d 21.Further study confirmed that differentially expressed genes induced by magnolol and honokiol supplementation enriched in cytokine-cytokine receptor interactions,in the intestinal immune network for IgA production,and in the cell adhesion molecule pathways.Conclusions:Supplemental magnolol and honokiol alleviated S.pullorum-induced impairments in growth performance,and the effect of magnolol was better than that of honokiol,which could be partially due to magnolol’s ability to improve the intestinal microbial and mucosal barrier. | Fang Chen Hao Zhang Encun Du Qiwen Fan Na Zhao Feng Jin Wei Zhang Wanzheng Guo Shaowen Huang Jintao Wei | 2022 | Journal of Animal Science and Biotechnology2022，13，1： | 9 |
| 5 | A flexible solid-state supercapacitor based on graphene/polyaniline paper electrodes显示文摘The direct coating of graphene sheets obtained by electrochemical exfoliation on commercial paper renders the preparation of highly conductive flexible paper substrate for subsequent deposition of polyaniline (PANi) nanorods via electrochemical polymerization. The deposit ion of PANi can be well-controlled by adjusting the electrochemical polymerization time, leading to the formation of PANi coated graphene paper (PANi-GP). The as-prepared electrode exhibited high areal capacitance of 176 mF cm^-2 in three-electrode system at a current density of 0.2 mA cm^-2 which is around 10 times larger than that of pris-tine graphene paper due to the pseudocapacitive behavior of PANi. In-situ Raman test was used to determine the molecular changes during redox process of PANi. More importantly, all-solid-state symmetric capacitor assembled with two PANi-GP electrodes in a polymer electrolyte delivered an areal capacitanee of 123 mF cm^-2, corresponding to an areal energy density of 17.1 μWh cm^-2 and an areal power density of 0.25 mW cm^-2. The symmetric capacitor held a capacitive retention of 74.8% after 500 bending tests from 0 to 120°, suggesting the good flexibility and mechanical stability. These results showed the great promising application in flexible energy-storage devices. | Kang Li Xuanli Liu Song Chen Wei Pan Jintao Zhang | 2019 | Journal of Energy Chemistry2019，28，5： | 5 |
| 6 | An 8–18 GHz power amplifier with novel gain fluctuation compensation technique in 65 nm CMOS显示文摘A wideband CMOS power amplifier with high gain and excellent gain flatness for X-Ku-band radar phased array is proposed in this paper. Excellent gain flatness is achieved with transformer based matching networks(TMNs), in which the gain fluctuation of an inter-stage matching network can be compensated by the proposed design methods. The circuit is fabricated in the TSMC 65 nm RF CMOS process. The proposed technique is verified by the measurement results, which show that the wideband PA achieves gain of 21-22.5 dB with only±0.75 dB gain fluctuation and 13-14.6 dBm flat output power between 7.5 and 15.5 GHz,and a little more ripple in the rest of the X-Ku band due to the inaccuracy of passive modelling at high frequency. The circuit delivers saturated and 1 dB-compressed output power of 14.6 and 11.3 dBm respectively at 13 GHz, for a maximal poweradded efficiency(PAE) of 23%. | Jie Gong Wei Li Jintao Hu Jiao Ye Tao Wang | 2018 | Journal of Semiconductors2018，39，12： | 2 |

| 12 | 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 |
| 13 | Highly efficient ternary organic solar cells with excellent open-circuit voltage and fill factor via precisely tuning molecular stacking and morphology显示文摘The micro-morphology and molecular stacking play a key role in determining the charge transport process and nonradiative energy loss, thus impacting the performances of organic solar cells(OSCs). To address this issue, a non-fullerene acceptor PhC6-IC-F with alkylbenzene side-chain, possessing optimized molecular stacking, complementary absorption spectra and forming a cascade energy level alignment in the PM6:BTP-eC9 blend, is introduced as guest acceptor to improve efficiency of ternary OSCs. The bulky phenyl in the side-chain can regulate crystallinity and optimizing phase separation between receptors in ternary blend films, resulting in the optimal phase separations in the ternary films. As a result, high efficiencies of 18.33% as photovoltaic layer are obtained for PhC6-IC-F-based ternary devices with excellent fill factor(FF) of 78.92%. Impressively, the ternary system produces a significantly improved open circuit voltage(V_(oc)) of 0.857 V compared with the binary device,contributing to the reduced density of trap states and suppressed non-radiative recombination result in lower energy loss. This work demonstrates an effective approach for adjusting the aggregation, molecular packing and fine phase separation morphology to increase V_(oc) and FF, paving the way toward high-efficiency OSCs. | Dinghong Sun Zhenyu Chen Jianfeng Zhang Wei Song Jingyu Shi Jintao Zhu Yuanyuan Meng Fei Jin Shuncheng Yang Ziyi Ge | 2024 | Science China Chemistry2024，67，3： | 0 |
| 14 | Microfluidics-assisted optimization of highly adhesive haemostatic hydrogel coating for arterial puncture显示文摘Although common in clinical practice,bleeding after tissue puncture may cause serious outcomes,especially in arterial puncture.Herein,gelatin-tannic acid composite hydrogels with varying compositions are prepared,and their adhesive properties are further optimized in microfluidic channel-based simulated vessels for haemostasis in arterial puncture.It is revealed that the composite hydrogels on the syringe needles used for arterial puncture should possess underwater adhesion higher than 4.9 kPa and mechanical strength higher than 86.0 kPa.The needles coated with the gelatin-tannic acid composite hydrogel completely prevent blood loss after both vein and arterial puncture in different animal models.This study holds great significance for the preparation of haemostatic needles for vessel puncture,and gelatin-tannic acid hydrogel coated needles may help to prevent complications associated with arterial puncture. | Xingjie Yin Jingli Ren Wei Lan Yu Chen Mengping Ouyang Hua Su Lianbin Zhang Jintao Zhu Chun Zhang | 2022 | Bioactive Materials2022，7，6： | 0 |

| 16 | The regulation of coordination structure between cobalt and nitrogen on graphene for efficient bifunctional electrocatalysis in Zn-air batteries显示文摘Electrocatalysts with atomically dispersed metal moieties are of importance in enhancing electrocatalysis for a specific reaction including oxygen reduction. However, it is still challenging to modulate the coordination structure of metal atoms with heteroatoms on carbon supports. Herein, an innovative and facile bridging strategy to regulate the coordination structure of cobalt with nitrogen atoms on reduced graphene oxide(r GO) sheets was developed by the interfacial complexation of amino-rich folic acid with cobalt ions on graphene oxide sheets and the subsequent thermal treatment. Typically, the actual coordination interaction between cobalt and nitrogen species was revealed by using X-ray absorption spectroscopy(XAS), exhibiting the Co-N_(4) coordination structure well-dispersed on reduced graphene oxide.Such unique structure enables the efficient oxygen reduction and evolution reactions via the favorable adsorption and desorption of intermediates. With the enhanced bifunctional electrocatalytic activities,the fabricated Zn-air battery exhibited the excellent performance with large power density of 319.8 mW cm^(-2) and good long-term stability(over 300 h). This work establishes the synthesis strategy for bridging metal atom with heteroatom on graphene sheets to enhance the bifunctional electrocatalysis toward Zn-air batteries. | Xinxin Shu Maomao Yang Miaomiao Liu Wei Pan Jintao Zhang | 2022 | Journal of Energy Chemistry2022，31，5： | 0 |
