| 1 | Study of flow induced by sine wave and saw tooth plasma actuators显示文摘The effect of plasma actuator that uses saw-tooth or sine-wave shape electrodes on boundary layer flows is experimentally investigated.The measurement results are compared with a corresponding standard configuration (conventional design using two rectangular strip electrodes)-the actuator that produces a nearly two-dimensional horizontal wall jet upon actuation.PIV measurements are used to characterize the actuators in a quiescent chamber.Operating in a steady manner,the new actuators result in the formation of streamwise and spanwise vortices.That is to say,the new actuators render the plasma actuators inducing three-dimensional variations in the shear layer,offering significant flexibility in flow control.The affected flowfield with the new actuators is significantly larger than that with the conventional linear actuators.While the conventional linear actuators affect primarily the boundary layer flow on a scale of about 1 cm above the wall,the new actuators affect the near wall region at a significantly larger scale.This new design broadens the applicability and enhances the flow control effects and it is potentially a more efficient flow control device. | LIU ZhiFeng WANG LianZe FU Song | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，11： | 12 |
| 2 | Effects of different fertilizations on fruit quality,yield and soil fertility in field-grown kiwifruit orchard显示文摘Kiwifruit yield and quality and soil nutrients were investigated in a kiwifruit orchard after long-term fertilization to understand the relationship between kiwifruit growth and soil nutrition.Seven fertilization treatments with three replications were applied in a continuous four-year period,including no fertilizer(CK);phosphorus(P)and potassium(K)fertilizers(PK);N and K fertilizers(NK);N and P fertilizers(NP);N,P and K fertilizers(NPK);1.5 times of N,P and K fertilizers(1.5NPK);and chemical fertilizers plus swine manure(NPKM).Fertilization increased kiwifruit yield at the rate of 450 kg N/hm^(2),225 kg P2O5/hm^(2),300 kg K2O/hm^(2).The average yield decreased in a descending order for NPKM(44.6 t/hm^(2)),1.5NPK(42.6 t/hm^(2)),NPK(42.0 t/hm^(2)),NK(38.0 t/hm^(2)),NP(36.7 t/hm^(2)),PK(36.4 t/hm^(2))and CK(34.1 t/hm^(2)).The sugar to acid ratio(S:A)was the highest(10.9)in 2012,and the soluble sugar increased by 15.7%after four-year NPKM fertilization.The NPKM fertilization also significantly increased the vitamin C,soluble solid and firmness.The soil organic carbon contents at 0-20 cm,20-40 cm and 40-60 cm in depth under the NPKM treatment were 27%,29%and 139%higher than that of the CK treatment,respectively.The available N contents at 0-20 cm,20-40 cm and 40-60 cm in depth in the 1.5NPK treatment were 180%,114%and 133%higher than that in the CK treatment,respectively.Balanced fertilization with N,P,K and organic manure is important to soil fertility,which may increase yield and improve quality in field-grown kiwifruit orchard. | Zhao Zuoping Duan Min Yan Sha Liu Zhifeng Wang Qi Fu Jing Tong Yan’an | 2017 | International Journal of Agricultural and Biological Engineering2017，10，2： | 6 |
| 3 | Allotransplantation of adult spinal cord tissues after complete transected spinal cord injury: long-term survival and functional recovery in canines显示文摘Spinal cord injury(SCI), especially complete transected SCI, leads to loss of cells and extracellular matrix and functional impairments. In a previous study, we transplanted adult spinal cord tissues(aSCTs) to replace lost tissues and facilitate recovery in a rat SCI model. However, rodents display considerable differences from human patients in the scale, anatomy and functions of spinal cord systems, and responses after injury. Thus, use of a large animal SCI model is required to examine the repair efficiency of potential therapeutic approaches. In this study, we transplanted allogenic aSCTs from adult dogs to the lesion area of canines after complete transection of the thoracic spinal cord, and investigated the long-term cell survival and functional recovery. To enhance repair efficiency, a growth factor cocktail was added during aSCT transplantation, providing a favorable microenvironment. The results showed that transplantation of a SCTs, in particular with the addition of growth factors, significantly improves locomotor function restoration and increases the number of neurofilament-, microtubule-associated protein2-, 5-hydroxytryptamine-, choline acetyltransferase-and tyrosine hydroxylase-positive neurons in the lesion area at 6 months post-surgery. In addition, we demonstrated that donor neurons in a SCTs can survive for a long period after transplantation. This study showed for the first time that transplanting aSCTs combined with growth factor supplementation facilitates reconstruction of injured spinal cords, and consequently promotes long lasting motor function recovery in a large animal complete transected SCI model, and therefore could be considered as a possible therapeutic strategy in humans. | He Shen Shuyu Wu Xi Chen Bai Xu Dezun Ma Yannan Zhao Yan Zhuang Bing Chen Xianglin Hou Jiayin Li Yudong Cao Xianyong Fu Jun Tan Wen Yin Juan Li Li Meng Ya Shi Zhifeng Xiao Xingjun Jiang Jianwu Dai | 2020 | Science China(Life Sciences)2020，63，12： | 3 |
| 4 | Polymer nanoparticles with dendrimer-Ag shell and its application in catalysis显示文摘Polymer nanoparticles with dendrimer-Ag shell were prepared and their application in catalytic reduction of 4-nitrophenol(4-NP) was investigated.Cross-linked polystyrene(PS) microspheres were prepared through dispersion copolymerization of styrene,acrylic acid and crosslinking monomer 1,2-divinylbenzene.PS microspheres with average size of 450 nm and narrow size distribution were used as support for the immobilization of dendrimer-Ag shell.The polyamidoamine(PAMAM) dendrimer shell was successively grafted onto the surface of PS microspheres through repetitive Michael addition reaction of methyl acrylate(MA) and amidation of the obtained esters with large excess of ethylenediamine(EDA).Silver nanoparticles were formed directly inside the PAMAM shell through reduction with NaBH_4.The resulting PS@PAMAM-Ag nanoparticles were packed in a stainless steel column and used successfully for catalytic reduction of 4-NP.This technique for packing catalytic polymer particles in a column could improve the efficiency of using the metal catalyst and the tedious separation in catalytic reaction. | Gaofei Dang Yan Shi Zhifeng Fu Wantai Yang | 2013 | Particuology2013，11，3： | 2 |
| 5 | Hydrogen-assisted scalable preparation of ultrathin Pt shells onto surfactant-free and uniform Pd nanoparticles for highly efficient oxygen reduction reaction in practical fuel cells显示文摘Concentrating active Pt atoms in the outer layers of electrocatalysts is a very effective approach to greatly reduce the Pt loading without compromising the electrocatalytic performance and the total electrochemically active surface area(ECSA)for the oxygen reduction reaction(ORR)in hydrogen-based proton-exchange membrane fuel cells.Accordingly,a facile,low-cost,and hydrogen-assisted two-step method is developed in this work,to massively prepare carbon-supported uniform,small-sized,and surfactant-free Pd nanoparticles(NPs)with ultrathin~3-atomic-layer Pt shells(Pd@Pt_(3L) NPs/C).Comprehensive physicochemical characterizations,electrochemical analyses,fuel cell tests,and density functional theory calculations reveal that,benefiting from the ultrathin Pt-shell nanostructure as well as the resulting ligand and geometric effects,Pd@Pt_(3L) NPs/C exhibits not only significantly enhanced ECSA,electrocatalytic activity,and noble-metal(NM)utilization compared to commercial Pt/C,showing 81.24 m^(2)/gPt,0.710 mA/cm^(2),and 352/577 mA/mgNM/Pt in ECSA,area-,and NM-/Pt-mass-specific activity,respectively;but also a much better electrochemical stability during the 10,000-cycle accelerated degradation test.More importantly,the corresponding 25-cm^(2) H2-air/O_(2) fuel cell with the low cathodic Pt loading of~0.152 mgPt/cm^(2)geo achieves the high power density of 0.962/1.261 W/cm^(2)geo at the current density of only 1,600 mA/cm^(2)geo,which is much higher than that for the commercial Pt/C.This work not only develops a high-performance and practical Pt-based ORR electrocatalyst,but also provides a scalable preparation method for fabricating the ultrathin Pt-shell nanostructure,which can be further expanded to other metal shells for other energy-conversion applications. | Liuxuan Luo Cehuang Fu Aiming Wu Zechao Zhuang Fengjuan Zhu Fangling Jiang Shuiyun Shen Xiyang Cai Qi Kang Zhifeng Zheng Chenyi Hu Jiewei Yin Guofeng Xia Junliang Zhang | 2022 | Nano Research2022，15，3： | 2 |

| 10 | Nonisothermal Crystallization Kinetics of Poly(butylene adipate-co-terephthalate) Copolyester显示文摘Nonisothermal crystallization behavior of poly(butylene adipate-co-terephthalate)(PBAT) synthesized via direct esterification and polycondensation reactions was investigated by the differential scanning calorimetry(DSC).The Avrami equation modified by Jeziorny and the Z.S.Mo equation were employed to describe the non-isothermal crystallization kinetics of copolyester samples.The test results showed that the Avrami equation was successful in describing nonisothermal crystallization process of PBAT copolyesters.PBAT copolyester could give birth to secondary crystallization.The crystallization parameter(Zc) increased with an increasing cooling rate and the Avrami exponent(n) was around 2.3.For a given cooling rate,the value of Zc demonstrated a sagging trend with an increase in adipic acid(AA) content.The equation proposed by Z.S.Mo was successful in describing the nonisothermal crystallization kinetics of PBAT copolyesters. | Wang Xiaohui Shi Jun Chen Ying Fu Zhifeng Shi Yan | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，1： | 1 |

| 17 | Significant improvement in data quality with simplified SCRB-seq显示文摘The ability to interrogate the transcriptomes of single cells with single-cell RNA-seq has transformed our view of a population of cells.Likewise,rather than interpreting results from a single population averaged cell type,the population response is now often described in terms of inherently different cell phenotypes,including those that are rare[1,2].Thus,a key application of single-cell RNAseq is to identify rare and new cell types otherwise undetected in the population,which forms the basis of their popularity in a wide range of studies of fundamental cellular processes including development,tissue function,and progression of diseases such as cancer. | Jian Ni Chuansheng Hu Hua Li Xinhui Li Qiong Fu Daniel M Czajkowsky Yan Guo Zhifeng Shao | 2020 | Acta Biochimica et Biophysica Sinica2020，52，4： | 1 |
