| 1 | De novo characterization of the root transcriptome of a traditional Chinese medicinal plant Polygonum cuspidatum显示文摘Various active components have been extracted from the root of Polygonum cuspidatum.However,the genetic basis for their activity is virtually unknown.In this study,25600002 short reads (2.3 Gb) of P.cuspidatum root transcriptome were obtained via Illumina HiSeq 2000 sequencing.A total of 86418 unigenes were assembled de novo and annotated.Twelve,18,60 and 54 unigenes were respectively mapped to the mevalonic acid (MVA),methyl-D-erythritol 4-phosphate (MEP),shikimate and resveratrol biosynthesis pathways,suggesting that they are involved in the biosynthesis of pharmaceutically important anthraquinone and resveratrol.Eighteen potential UDP-glycosyltransferase unigenes were identified as the candidates most likely to be involved in the biosynthesis of glycosides of secondary metabolites.Identification of relevant genes could be important in eventually increasing the yields of the medicinally useful constituents of the P.cuspidatum root.From the previously published transcriptome data of 19 non-model plant taxa,1127 shared orthologs were identified and characterized.This information will be very useful for future functional,phylogenetic and evolutionary studies of these plants. | HAO DaCheng MA Pei MU Jun CHEN ShiLin XIAO PeiGen PENG Yong HUO Li XU LiJia SUN Chao | 2012 | Science China(Life Sciences)2012，55，5： | 36 |
| 2 | Au nanoring arrays with tunable morphological features and plasmonic resonances显示文摘Gold nanoring arrays are widely applied in various fields benefitting from their localized surface plasmon resonance(LSPR)properties.A key advantage of gold nanoring arrays is that the dipole resonance peak can be systematically tuned by changing the dimensions of gold nanoring arrays.However,most of the currently reported methods for preparing gold nanoring arrays cannot conveniently control the heights of the nanorings at a low cost.Here we introduce a facile method for preparing gold nanoring arrays with tunable plasmonic resonances using colloidal lithography.The dimensions of the nanorings including diameters,lattice constants,even the heights of the nanorings can be conveniently varied.Fourier transform near-infrared(FT-NIR)absorption spectroscopy was used to obtain the plasmonic resonance spectra of the nanoring arrays.All the prepared gold nanoring arrays exhibited a strong NIR or infrared(IR)plasmonic resonance which can be tuned by varying the nanoring dimensions.This versatile method can also be used to fabricate other types of plasmonic nanostructures,such as gold nanocone arrays.The obtained gold nanoring arrays as well as nanocone arrays may have potential applications in surface-enhanced spectroscopy or plasmonic sensing. | Shilin Mu Hongxu Chen Chenyu Shi Junhu Zhang Bai Yang | 2021 | Nano Research2021，14，12： | 1 |

| 4 | Parameter Optimization via Orthogonal Experiment to Improve Accuracy of Metakaolin Ceramics Fabricated by Direct Ink Writing显示文摘Kaolin/metakaolin-insulating ceramic components fabricated using direct ink writing(DIW)have important ap-plication prospects in architecture and aerospace.The accuracy of the entire process including the forming and sintering accuracy of ceramics greatly limits the application scope,and high-accuracy ceramic samples can meet the usage requirements in many scenarios.The orthogonal experiment was designed with four process parame-ters,including nozzle internal diameter,filling rate,printing layer height/nozzle internal diameter,and printing speed,to investigate the evolution of the DIW forming accuracy,sintering shrinkage rate and surface roughness of metakaolin-based ceramics with different process parameters.The influence of each process parameter and its mechanism were analyzed to obtain the DIW parameters for high-accuracy metakaolin ceramics.Multiple linear regression models between the dimensional change rate,surface roughness,and process parameters of the ceramic samples were established and validated.The results show that comprehensively considering the forming accuracy of the ceramic green bodies,sintering shrinkage rate and surface roughness,the optimal DIW process parameters were a 0.41 mm nozzle internal diameter,100%filling rate,50%printing layer height/nozzle inter-nal diameter,and a 15 mm/s printing speed.Multiple linear regression models were developed for the process parameters and the printing accuracy,sintering shrinkage rate and surface roughness.The error rates between the theoretical results obtained by substituting the optimal process parameters into the multiple linear regression models and the actual results obtained by printing the samples with the optimal parameters were extremely small,all less than 0.8%.This verified the correctness and predictability of the multiple linear regression models.This work provides a reference basis for rapid fabrication of high-accuracy ceramics via DIW and accuracy prediction with different process parameters. | Ming Wu Fuchu Liu Yuxiao Lin Miao Wang Shilin Zhou Chi Zhang Yingpeng Mu Guangchao Han Liang Hao | 2023 | Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2023，2，4： | 0 |
