1Genetic analysis and gene mapping of a narrow leaf mutant in rice (Oryza sativa L.)显示文摘A narrow leaf mutant was obtained after T-DNA transformation conducted on a rice variety Zhonghua 11. Several abnormal morphological characteristics, including semi-dwarf, delayed flowering time, narrow and inward rolling leaves, and lower seed-setting, were observed. The rate of net photosynthesis (un-der saturate light) of flag leaves in the mutant was significantly lower than that of the wild type. More-over, the leaf transpiration rate and stomatal conductance in the mutant flag leaf were lower than those of the wild type at the grain filling stage. It was found that the mutant phenotype was not caused by the T-DNA insertion. Genetic analysis showed that the mutant was controlled by a single recessive gene, designated as nal3(t). A genetic linkage map was constructed using a large F2 mapping population de-rived from a cross between nal3(t) and an indica variety Longtefu B with 6 polymorphic markers on chromosome 12 identified from 366 SSR markers by the BAS method. Gene nal3(t) was mapped be-tween the markers RM7018 and RM3331. Fine mapping of nal3(t) locus was conducted with 22 newly developed STS markers based on the sequence diversity around the region harboring nal3(t) between Nipponbare and 93-11, and nal3(t) was finally mapped to a 136-kb region between the STS markers NS10 and RH12-8.WANG DeKai LIU HeQin LI KeLei LI SuJuan TAO YueZhi 2009Chinese Science Bulletin2009,54,5:19
2Retrospective study on Professor Zhongying Zhou's experience in Traditional Chinese Medicine treatment on diabetic nephropathy显示文摘OBJECTIVE:To study and analyze the etiology and pathogenesis,diagnosis and prescription for cases of diabetic nephropathy(DN) treated by Professor Zhongying Zhou(Prof.Zhou) with the help of dada mining technique,so as to inherit his clinical experience and academic thoughts.METHODS:After pretreatment of the medical record information,statistical software SPSS 13.0 was used to analyze and process the standardized data using the descriptive analysis,cluster analysis and association rules.RESULTS:Ninety-four entries derived from Traditional Chinese Medicine(TCM) four-diagnostic information were selected.Through data mining,the highest frequency was yellow-thin-greasy tongue coating,followed by dark tongue,and then by thready-slippery pulse.The main self-conscious symptoms were limb numbness,dry mouth,frequent micturition,etc.With respect to pathogenesis,the etiology related to kidney reached 73.46%.The frequency of pathological factors for deficiency,blood stasis,heat,dampness,phlegm and dryness were 137.65%,80.25%,78.40%,48.77%,21.60%,and 14.20% respectively.A total of 236 kinds of herbs were used 2913 person times,averaging 17.98 herbs per prescription.CONCLUSION:The pathological location of DN is in the kidney.The pathogenesis of the disease is deficiency in origin and excess in superficiality,the former of which include deficiency of the liver and kidney,and deficiency of both Qi and Yin.The main pathological factors are blood stasis,heat,dampness,phlegm,and dryness;and they act upon each other to form the complex pathogenesis in terms of blood stasis-heat,dampness-heat,phlegm-heat,and dryness-heat.All the above factors are always crucial in the aggravation of DN throughout the whole course of its pathological evolution.Kelei Su Fangshi Zhu Lizhong Guo Yao Zhu Wenlin Li Xingjiang Xiong 2013Journal of Traditional Chinese Medicine2013,33,2:11

4Nitrogen and sulfur co-doped graphene aerogel with hierarchically porous structure for high-performance supercapacitors显示文摘Supercapacitors with unique performance have been widely utilized in many fields. Herein, we report a nitrogen and sulfur co-doped graphene aerogel(N/S-GA-2) prepared using a low toxic precursor for high-performance supercapacitors. The as-obtained material possesses a hierarchically porous structure and a large number of electrochemical active sites. At a current density of 1 Ag^-1, the specific capacitance of the N/S-GA-2 for supercapacitors with the ionic liquid as the electrolyte is 169.4 Fg^-1, and the corresponding energy density is 84.5 Wh kg^-1.At a power density of 8.9 k W kg^-1, the energy density can reach up to 75.7 Wh kg^-1, showing that the N/S-GA-2 has an excellent electrochemical performance. Consequently, the N/S-GA-2 can be used as a promising candidate of electrode materials for supercapacitors with high power density and high energy density.Zhiwei Lu Xiaochao Xu Yujuan Chen Xiaohui Wang Li Sun Kelei Zhuo 2020Green Energy & Environment2020,5,1:3

6Additional symmetries of constrained CKP and BKP hierarchies显示文摘The additional symmetries of the constrained CKP (cCKP) and BKP (cBKP) hierarchies are given by their actions on the Lax operators, and their actions on the eigenfunction and adjoint eigenfunction {Φ i , Ψ i } are presented explicitly. Furthermore, we show that acting on the space of the wave operator, *k forms new centerless W cC 1+∞ and W cB 1+∞ -subalgebra of centerless W 1+∞ respectively. In order to define above symmetry flows *k of the cCKP and cBKP hierarchies, two vital operators Y k are introduced to revise the additional symmetry flows of the CKP and BKP hierarchies.TIAN KeLei HE JingSong CHENG JiPeng CHENG Yi 2011Science China Mathematics2011,54,2:3
7Influence of CaO and HZSM-5 on oxygen migration in Chlorella vulgaris polysaccharide pyrolysis显示文摘With polysaccharides of Chlorella pyrenoidosa as the raw material,the effects of CaO and HZSM-5 on the yield of bio-oil and the oxygen content in each phase in the pyrolysis of Chlorella vulgaris polysaccharides(CVP),which occurred in a tube furnace at 600℃,were comprehensively investigated.The reaction path of deoxidation was also analyzed by TG,GC and GC-MS.The GC-MS analysis of liquids showed that liquids from the pyrolysis of chlorella polysaccharides included a range of light oxygenated compounds(e.g.,furans,ketones and phenols),and the oxygen content of furan compounds decreased significantly with CaO and HZSM-5.Compared with the direct pyrolysis of polysaccharides(CVP),the catalytic pyrolysis contributed to the decrease in the oxygen content of organic components by 7.32%and 5.76%.The GC analysis showed that there was a remarkable downtrend in the release of oxygen-containing gas(CO and CO_(2)),and the emission of CO_(2) decreased from 53.11%to 32.92%.The results of the thermogravimetric analysis indicated that the reaction paths of deoxidation in the pyrolysis process of polysaccharides(CVP)with CaO and HZSM-5 varied from those of the direct pyrolysis process:the catalytic pyrolysis with HZSM-5 promoted the conversion of carbohydrate from furans to aromatics over strong acid sites,which was consistent with previous studies;CaO not only acted as a catalyst but also participated in the reaction to change the reaction paths.All results and findings can help to further understand the thermochemical utilization of CPP for bio-oil.Xiuli Zhang Chunhu Li Anhong Tian Qingjie Guo Kelei Huang 2019Carbon Resources Conversion2019,2,2:3
8Aerodynamic design of tractor propeller for high-performance distributed electric propulsion aircraft显示文摘Aiming to maximize the aerodynamic performance of the Distributed Electric Propulsion(DEP)aircraft,a hybrid design framework which focuses on the aerodynamic performance of the propeller/wing integration has been developed and validated numerically.Variable-fidelity modelling for propeller aerodynamics has been used to achieve computational efficiency with reasonable accuracy.By optimizing the aerodynamic loading distributions on the tractor propeller disk,the induced slipstream is redistributed into a form that is beneficial for the wing downstream,based on which the propeller blade geometry is generated through a rapid inversed design procedure.As compared with the Minimum Induced Loss(MIL)propeller at a specified thrust level,significant improvements of both the lift-to-drag ratio of the wing and the propeller/wing integrated aerodynamic efficiency is achieved,which shows great promise to deliver aerodynamic benefits for the wing within the propeller slipstream without any additional devices.Kelei WANG Zhou ZHOU Zhongyun FAN Jiahao GUO 2021Chinese Journal of Aeronautics2021,34,10:2
9Self-assembly synthesis of phosphorus-doped tubular g-C_(3)N_(4);Ti_(3)C_(2)MXene Schottky junction for boosting photocatalytic hydrogen evolution显示文摘Establishing highly effective charge transfer channels in carbon nitride(g-C_(3)N_(4)) to enhance its photocatalytic activity is still a challenging issue.Herein,the delaminated 2D Ti_(3)C_(2) MXene nanosheets were employed to decorate the P-doped tubular g-C_(3)N_(4)(PTCN)for engineering 1D/2D Schottky heterojunction(PTCN/TC)through electrostatic self-assembly.The optimized PTCN/TC exhibited the highest hydrogen evolution rate(565 μmol h^(-1)g^(-1)),which was 4.3 and 2.0-fold higher than pristine bulk g-C_(3)N_(4) and PTCN,respectively.Such enhancement may be primarily attributed to the phosphorus heteroatom doped and unique structure of 1D/2D g-C_(3)N_(4)/Ti_(3)C_(2) Schottky heterojunction,enhancing the light-harvesting and charges’separation.One-dimensional pathway of g-C_(3)N_(4) tube and built-in electric field of interfacial Schottky effect can significantly facilitate the spatial separation of photogenerated charge carriers,and simultaneously inhibit their recombination via Schottky barrier.In this composite,metallic Ti_(3)C_(2) was served as electrons sink and photons collector.Moreover,ultrathin Ti_(3)C_(2) flake with exposed terminal metal sites as a co-catalyst exhibited higher photocatalytic reactivity in H2 evolution compared to carbon materials(such as reduced graphene oxide).This work not only proposed the mechanism of tubular g-C_(3)N_(4)/Ti_(3)C_(2) Schottky junction in photocatalysis,but also provided a feasible way to load ultrathin Ti_(3)C_(2) as a co-catalyst for designing highly efficient photocatalysts.Kelei Huang Chunhu Li Xiuli Zhang Liang Wang Wentai Wang Xiangchao Meng 2023Green Energy & Environment2023,8,1:2
10Cetyltrimethylammonium Bromide(CTAB)-Ionic Liquid Composite Modified Electrode for Sensitive Cyclic Voltammetric Determination of Bisphenol A显示文摘A sensitive electrochemical sensor for determining bisphenol A(BPA) was designed. The sensor was aglassy carbon electrode modified with the surfactant cetyltrimethylammonium bromide and the ionic liquid1-decyl-3-methylimidazolium tetrafluoroborate. The ability of the new sensor to measure BPA was investigated incyclic voltanmletry experiments. Under optimized conditions, the sensor gave a linear response range for BPA of2.19×10^-7 -3.28× 10^-5 mol/L and a detection limit of 7.31×10^8 mol/L(S/N=3) BPA could be determined with a lowerdetection limit, a wider linear range, and more sensitivity using the sensor than using other electrochemical sensors orhigh performance liquid chromatography with UV detection. The new sensor was used to determine BPA in tap waterwith recoveries of 97.5%--98.7% and a relative standard deviation 〈2.9%. The results show that the sensor can beused to determine trace BPA concentrations in tap water.LIU Lihong WANG Chunfeng ZHUO Kelei 2016Chemical Research in Chinese Universities2016,32,6:2

16Performance of anaerobic fluidized bed microbial fuel cell with different porous anodes显示文摘Anode materials were used to construct microbial fuel cells(MFCs),and the characteristics of the anodes were important for successful applied performance of the MFCs.Via the cyclic voltammetry(CV)method,the experiments showed that 5 wt%multiwalled carbon nanotubes(MWNTs)were optimal for the PANI/MWNT film anodes prepared using 24 polymerization cycles.The maximum output voltage of the PANI/MWNT film anodes reached 967.7 mV with a power density of 286.63 mW·m-2.Stable output voltages of 860 mV,850 mV,and870 mV were achieved when the anaerobic fluidized bed microbial fuel cell(AFBMFC)anodes consisted of carbon cloth with carbon black on one side,copper foam and carbon brushes,respectively.Pretreatment of the anodes before starting the AFBMFC by immersion in a stirred bacterial fluid significantly shortened the AFBMFC startup time.After the AFBMFC was continuously run,the anode surfaces generated active microbial catalytic material.Xiuli Zhang Chunhu Li Qingjie Guo Kelei Huang 2020Chinese Journal of Chemical Engineering2020,28,3:1
