| 1 | Direct growth of special-shape graphene on different templates by remote catalyzation of Cu nanoparticles显示文摘A novel method avoiding the complex transfer process is proposed to directly grow low-defect and few-layer graphene on different insulating substrates(SiO_2, Al_2O_3, etc.) by remote catalyzation of Cu nanoparticles(NPs) using ambient pressure chemical vapor deposition(APCVD). The insulating substrates with special structure are used as templates to grow wrapped graphene sheets with special shapes.Hollow graphene species are obtained by removing the substrates. The prime feature of the proposed method is using Cu NPs as catalyst rather than metal foils. The Cu NPs play an important role in the remote catalyzation during the nucleation of graphene. This method can improve the quality and relatively decrease the growth temperature of the graphene on the insulating substrates, which displays the great potential of APCVD direct growth of graphene on dielectric substrates for electronic and photovoltaic applications. | Shuangshuang Han Fan Yang Liyue Liu Mi Zhou Yongkui Shan Dezeng Li | 2017 | Journal of Materials Science & Technology2017，33，8： | 1 |
| 2 | A comprehensive review:Research status and trends of planarianology in China显示文摘Planarian is an excellent model for studying several scientific issues,and planarianology has become an active research field in the world.Researchers at home and abroad have conducted a lot of in-depth studies on planarians in various areas.This paper outlined the panorama of planarian research in China and summarized the advances from three aspects of taxonomy,molecular phylogeny and phylogeography,regeneration,tissue homeostasis and immunity as well as toxicology.Furthermore,the current problems and future development direction and tendency of planarian research in China are briefly analyzed and prospected.Importantly,the catalogue of planarians in China is also presented. | Hecai Zhang Junhua He Changying Shi Guangwen Chen Dezeng Liu | 2023 | Zoological Systematics2023，48，2： | 0 |
| 3 | Genetic diversity,population structure and demographic history of Dugesia japonica in Taihang Mountains显示文摘The freshwater planarian Dugesia japonica has become a model organism in regeneration biology and toxicology due to its powerful regeneration capability and highly chemical sensitivity.Nonetheless,little is known about its evolutionary history and demographics.Taihang Mountains is the natural boundary between the Loess Plateau and the North China Plain,and is considered as one of the important priority areas for biodiversity conservation in China.In order to figure out the genetic diversity,population structure and demographic history of D.japonica in Taihang Mountains,a study based on the mitochondrial COI from 116 individuals sampled across 20 populations has been conducted.The results showed that the 116 COI sequences yielded 32 haplotypes,including 8 shared haplotypes and 24 private ones.The overall haplotype diversity(Hd)and nucleotide diversity(π)were 0.920 and 0.083,respectively.Even though the AMOVA results suggested that the genetic variation among populations was significant(FST=0.480,P<0.01),the phylogeny and haplotype network analysis based on 32 haplotypes revealed no obvious phylogeographic pattern.Furthermore,the significantly positive values of neutrality test(Tajima’s D=2.596,P<0.05;Fu’s Fs=2.769,P<0.01)together with the multimodal arrangement of mismatch distribution indicated that D.japonica in Taihang Mountains would have been undergoing population decline.We hope these findings will arouse conservation and management strategy regarding freshwater planarians and contribute to the biodiversity in the long run. | Hecai Zhang Tiange Hu Changying Shi Guangwen Chen Dezeng Liu | 2021 | Zoological Systematics2021，46，2： | 0 |
| 4 | Efficiency Enhancement of Cu(In,Ga)Se_2 Solar Cells by Applying SiO_2-PEG/PVP Antire flection Coatings显示文摘An effective approach was presented to enhance photoelectric conversion efficiency of Cu(In,Ga)Se2 (CIGS) solar cells by using modified SiO2 antireflection coatings(ARCs) to harvest more incident sunlight.Polyethylene glycol(PEG) and polyvinyl pyrrolidone(PVP) used as additives were introduced into silica sols to prepare SiO2-PEG and SiO2-PVP coatings in the sol-gel dip-coating process,respectively. The different effects of PEG and PVP additives on SiO2 coatings were analyzed and the antireflection performance of SiO2-PEG and SiO2-PVP coatings was investigated. The transmittance over 97% ranging from 450 nm to 700 nm with a maximum transmittance over 99.40% at about 550 nm was achieved for both SiO2-PEG2000A and SiO2-PVP0.5 coatings. The relative efficiencies of CIGS solar cells coated with SiO2-PEG2000A and SiO2-PVP0.5 ARCs were increased by 7.27% and 8.33%,respectively. The modified SiO2 ARCs possessed the advantages of the low manufacturing cost,good adhesion,superior antireflective performance and the feasible method for large area fabrication. | Dezeng Li Zhanqiang Liu Yaoming Wang Yongkui Shan Fuqiang Huang | 2015 | Journal of Materials Science & Technology2015，31，2： | 0 |
| 5 | Photokinesis and Djopsin gene expression analysis during the regeneration of planarian eyes显示文摘Planarians provide the ideal model for studying eye development,with their simple eye structure and exceptionally rapid regeneration.Here,we observed the eye morphogenesis,photophobic behavior,spectral sensitivity and expression pattern of Djopsin in the freshwater planarian Dugesia japonica.The results showed that:(i)Djopsin encoding the putative protein belonged to the rhabdomeric opsins group and displayed high conservation during animal evolution;(ii)planarians displayed diverse photophobic response to different visible wavelengths and were more sensitive to light blue(495 nm)and yellow(635 nm);(iii)the morphogenesis and functional recovery of eyes were related to the expression pattern of Djopsin during head regeneration;and(iv)Djopsin gene plays a major role in functional recovery during eye regeneration and visual system maintenance in adult planarians. | Zimei DONG Yanqing YUWEN Yingxu SIMA Yanping DONG Huina ZHAN Guangwen CHEN Dezeng LIU | 2017 | Integrative Zoology2017，12，2： | 0 |
| 6 | Integrative taxonomy unveils a new species of Dugesia(Platyhelminthes,Tricladida,Dugesiidae)from the southern portion of the Taihang Mountains in northern China,with the description of its complete mitogenome and an exploratory analysis of mitochondrial gene order as a taxonomic character显示文摘A new species of Dugesia(Platyhelminthes,Tricladida,Dugesiidae)from northern China is described on the basis of an integrative approach,involving morphology,karyology,histology,molecular distance,molecular phylogeny,and mitochondrial gene order.Here,we present the complete mitogenome of the new species Du-gesia constrictiva Chen&Dong,sp.nov.This new species is mainly characterized by the presence of the following features:asymmetrical openings of the oviducts;large,cuboidal copulatory bursa;vasa deferentia opening through the ventro-lateral wall of the seminal vesicle;laterally compressed seminal vesicle;ventrally displaced ejaculatory duct,opening at the blunt tip of the penis papilla;long duct intercalated between semi-nal vesicle and diaphragm;chromosome complement diploid,with 16 metacentric chromosomes;mitochondrial gene order as follows:cox1-E-nad6-nad5-S2-D-R-cox3-I-Q-K-atp6-V-nad1-W-cox2-P-nad3-A-nad2-M-H-F-rrnS-L1-Y-G-S1-rrnL-L2-T-atp8-C-N-cob-nad4l-nad4.In triclads,mitochondrial gene order is considerably conserved between freshwater planarians and landflatworms,whereas it is variable between marine planarians and both fresh-water and landflatworms.The secondary structures of tRNAs are all equipped with 4 arms,excepting tRNA S1 and tRNA S2,which lack the D arm and have excessively enlarged loops.Numerous transpositions of tRNA are present between D.constrictiva and its congeners.Mitochondrial gene arrangements may form a new,additional tool for taxonomic studies.The phylogenetic tree based on analysis of the mitochondrial genome basically corroborates current classification of the higher taxa of planarianflatworms. | Lei WANG Yixuan WANG Zimei DONG Guangwen CHEN Ronald SLUYS Dezeng LIU | 2022 | Integrative Zoology2022，17，6： | 0 |
| 7 | Systematic identification and screening of functional long noncoding RNAs during planarian regeneration显示文摘Freshwater planarians(Platyhelminthes)are ideal models in regenerative biology because of their whole-body regeneration capability(Salo,2006).They are also popular in neuroscience because they possess anterior cephalic ganglia(brains),which can be restored within a week after head removal(Ross et al.,2017). | Baijie Jin Nannan Li Lina Pang Jing Xiao Ziyi Lin Ning Li Zimei Dong Guangwen Chen Fei Yu Dezeng Liu | 2023 | Journal of Genetics and Genomics2023，50，12： | 0 |
