| 1 | Palaeoecological and palaeoenvironmental significance of someimportant spores and micro-algae in Quaternary deposits显示文摘Spores of ferns and allied plants, and micro-algae frequently occur in abundance in Quaternary deposits, but their palaeoenvironmental significance is seldom evaluated. This paper presents morphological descriptions of spores of Selaginella sinensis (Desv.) Spring, 1843 (Selaginellaceae) and Ceratopteris cf. thalictroides (L.) Brongniart, 1821 (Parkeriaceae) and the algae Pediastrum boryanum (Turpin) Meneghini, 1840, P. simplex Meyen, 1829, P. integrum N geli, 1849 (all Hydrodictyaceae), Spiniferites Mantell, 1850, emend. Sarjeant, 1970 (Spiniferitaceae) and Concentricystes Rossignal, 1962, emend. Jiabo, 1978 (systematic position unclear), and discusses their occurrence in mostly Quaternary sedimentary successions. All are closely associated with aquatic habitats. Extant Selaginella sinensis often colonizes fairly wet hillsides and gaps between rocks, and shady sides of ravines and slopes; it is also found within thickets of trees and shrubs (boscages) and in forests with calcareous soils. Ceratopteris thalictroides, Pediastrum and Concentricystes inhabit freshwater lakes and both natural and artificial wetlands, such as paddy fields and ditches. Spiniferites is a salt-water genus and usually associated with the marine realm. Fossil and subfossil representatives of all of these taxa can be useful proxies of biodiversity and, therefore, also important for determining environmental conditions during the Quaternary period. | TANG LingYu MAO LiMi Lü XinMiao MA QingFeng ZHOU ZhongZe YANG ChunLei KONG ZhaoChen BATTEN David J | 2013 | Chinese Science Bulletin2013，58，25： | 9 |
| 2 | Analysis of abnormal texture formation and strengthening mechanism in an extruded Mg-Gd-Y-Zn-Zr alloy显示文摘A Mg-Gd-Y-Zn-Zr magnesium alloy with different initial states was extruded under different extrusion parameters.The effect of solution treatment and extrusion parameters on the microstructure,texture and mechanical properties were analyzed in detail,and the abnormal texture formation and strengthening mechanism was revealed.When extruded at low temperature and small extrusion ratio,the bimodal microstructure consisting of fine dynamically recrystallized grains and coarse deformed grains occurred both in the as-cast alloy and solution-treated alloy.When the extrusion temperature and extrusion ratio were increased,the amount and size of dynamically recrystallized grains increased and the grain size of the solution-treated alloy showed higher growth rate.Furthermore,an abnormal texture with<0001>parallel with extrusion direction developed due to the occurrence of non-basal slip and continuous dynamic recrystallization.This could be enhanced by solution treatment,high temperature,and large extrusion ratio.Both the as-cast alloy and solution-treated alloy exhibited the highest tensile strength after extrusion at 300℃with an extrusion ratio of 9.Grain refinement was the main strengthening mechanism utilized in both the as-cast alloy and the solution-treated alloy.Work hardening played an important role in the sample extruded at low temperature and small extrusion ratio,with the highest contribution of about 33 MPa after extrusion at 300℃with an extrusion ratio of 9.Texture strengthening contributed more in the sample extruded at high temperature and large extrusion ratio,but no more than 24.1 MPa.Solution strengthening was another strengthening mechanism in the extruded as-cast alloy,especially at high temperature and large extrusion ratio(no more than 9 MPa). | Xueze Jin Wenchen Xu Zhongze Yang Can Yuan Debin Shan BugangTeng Bo Cheng Jin | 2020 | Journal of Materials Science & Technology2020，42，10： | 7 |

| 5 | Process design and microstructure-property evolution during shear spinning of Ti_(2)AlNb-based alloy显示文摘Rotationally symmetric workpieces of Ti_(2)AlNb-based alloys have great potential for high-temperature service condition in aviation industry,while the poor workability limits their application until now.In this study,shear spinning and heat treatment were first conducted to investigate the corresponding microstructure evolution and mechanical properties of Ti_(2)AlNb conical workpieces.The microstructure of the 1^(st) and 2^(nd) pass spun workpieces(SP1 and SP2)mainly consisted of B2+retainedα2phases.After two passes spinning,the B2 phase texture changed from<111>//ND of as-received alloy to be<001>//ND.The ultimate tensile stress(UTS)of SP1 and SP2 was increased to 1163 MPa and 932 MPa,respectively,compared with 782 MPa of as-received alloy at 650℃.Also,the yield stress anomaly(YSA)occurred in SP1 and SP2 because{110}<111>and{112}<111>cross slip systems of B2 phase were difficult to slip at or below room temperature(RT),but they became active at 650℃ and above.As an essential step for increasing the spinnability of multi-pass spinning process of the Ti_(2)AlNb alloy,the H3heat treatment scheme,i.e.960℃/2 h+850℃/12 h,was carried out between two successive passes to increase the hot workability,by which the ductility of the heat treated as-spun workpieces with the microstructure of B2+primary O+acicular secondary O+high amount spheroidizedα2phases reached 72.1%at 900℃.After being subject to the H1 heat treatment scheme,i.e.960℃-2 h,the spun workpieces with the microstructure of B2+primary O+intergranular primaryα2phases achieved an optimized comprehensive mechanical properties both at room temperature and 650℃,which should be chosen as the post-spinning heat treatment process for the service requirement. | Sibing Wang Wenchen Xu Bin Shao Guoping Yang Yingying Zong Wanting Sun Zhongze Yang Debin Shan | 2022 | Journal of Materials Science & Technology2022，，6： | 1 |

| 8 | Effect of power spinning and heat treatment on microstructure evolution and mechanical properties of duplex low-cost titanium alloy显示文摘The microstructural evolution and mechanical properties of low-cost Ti-5.5Al-1Fe-3.5Cr-3.2Zr-0.2Si al-loy during power spinning and after three types of heat-treatment routines(low-temperature anneal-ing,high-temperature annealing,solution and annealing)were systematically studied.An effective heat-treatment routine to fabricate high-strength and acceptable ductile as-spun Ti-5.5Al-1Fe-3.5Cr-3.2Zr-0.2Si alloy tubes was then proposed whereby the relationship between the mechanical performances and mi-crostructures was analyzed.The{0002}_(α)and{001}_(β)textures were formed after multi-pass power spin-ning.The as-spun LC-Ti alloy exhibited a good combination of strength and elongation after heat treat-ment at 550℃for 4 h,which was ascribed to the large plastic induced low-temperature spheroidization of deformedαphase and nanoscaleαprecipitation from deformedβphase.However,the elongation de-creased evidently when Zr2Si/TiCr2 participated at the interphase boundaries after heat treatment at 550℃for 8 h.In high-temperature annealing,the elongation changed nonlinearly owing to the precipitation of Zr2Si particles at triangular grain boundaries treated at 750℃for 1 h,and the spheroidization of the deformedα_(p)phase.Under solution and annealing conditions,lenticularαs would participate from the metastableβgrains,which contributed to the greatest strength albeit poor ductility.This study provides an effective guidance for the processing and application of the low-cost titanium alloy. | Zhongze Yang Wenchen Xu Weiqing Zhang Yu Chen Debin Shan | 2023 | Journal of Materials Science & Technology2023，，5： | 0 |
| 9 | Organoids revealed:morphological analysis of the profound next generation in-vitro model with artificial intelligence显示文摘In modern terminology,“organoids”refer to cells that grow in a specific three-dimensional(3D)environment in vitro,sharing similar structures with their source organs or tissues.Observing themorphology or growth characteristics of organoids through a microscope is a commonly used method of organoid analysis.However,it is difficult,time-consuming,and inaccurate to screen and analyze organoids only manually,a problem which cannot be easily solved with traditional technology.Artificial intelligence(AI)technology has proven to be effective in many biological and medical research fields,especially in the analysis of single-cell or hematoxylin/eosin stained tissue slices.When used to analyze organoids,AI should also provide more efficient,quantitative,accurate,and fast solutions.In this review,we will first briefly outline the application areas of organoids and then discuss the shortcomings of traditional organoid measurement and analysis methods.Secondly,we will summarize the development from machine learning to deep learning and the advantages of the latter,and then describe how to utilize a convolutional neural network to solve the challenges in organoid observation and analysis.Finally,we will discuss the limitations of current AI used in organoid research,as well as opportunities and future research directions. | Xuan Du Zaozao Chen Qiwei Li Sheng Yang Lincao Jiang Yi Yang Yanhui Li Zhongze Gu | 2023 | Bio-Design and Manufacturing2023，6，3： | 0 |
| 10 | OOCDB:A Comprehensive,Systematic,and Real-time Organs-on-a-chip Database显示文摘Organs-on-a-chip is a microfluidic microphysiological system that uses microfluidic technology to analyze the structure and function of living human cells at the tissue and organ levels in vitro.Organs-on-a-chip technology,as opposed to traditional two-dimensional cell culture and animal models,can more closely simulate pathologic and toxicologic interactions between different organs or tissues and reflect the collaborative response of multiple organs to drugs.Despite the fact that many organs-on-a-chip-related data have been published,none of the current databases have all of the following functions:searching,downloading,as well as analyzing data and results from the literature on organs-on-a-chip.Therefore,we created an organs-on-a-chip database(OOCDB)as a platform to integrate information about organs-on-a-chip from various sources,including literature,patents,raw data from microarray and transcriptome sequencing,several open-access datasets of organs-on-a-chip and organoids,and data generated in our laboratory.OOCDB contains dozens of sub-databases and analysis tools,and each sub-database contains various data associated with organs-on-a-chip,with the goal of providing researchers with a comprehensive,systematic,and convenient search engine.Furthermore,it offers a variety of other functions,such as mathematical modeling,three-dimensional modeling,and citation mapping,to meet the needs of organs-on-a-chip. | Jian Li Weicheng Liang Zaozao Chen Xingyu Li Pan Gu Anna Liu Pin Chen Qiwei Li Xueyin Mei Jing Yang Jun Liu Lincao Jiang Zhongze Gu | 2023 | Genomics, Proteomics & Bioinformatics2023，21，2： | 0 |
| 11 | A Hf_(0.5)Zr_(0.5)O_(2)ferroelectric capacitor-based half-destructive read scheme for computing-in-memory显示文摘The emerging non-volatile memories(NVMs),including resistive random access memory(RRAM)[1],phase-change memory(PCM)[2],and ferroelectric random access memory(Fe RAM)[3],have broad application prospects owing to their non-volatility and near-zero static energy consumption.Compared to other NVMs,ferroelectric capacitors(Fe CAPs)ofer advantages in energy consumption and endurance.However,the destructive read operation of capacitors(e.g.,DRAMs and Fe CAPs)destroys the stored data. | Yulin ZHAO Yuan WANG Donglin ZHANG Zhongze HAN Qiao HU Xuanzhi LIU Qingting DING Jinhui CHENG Wenjun ZHANG Yue CAO Ruixi ZHOU Qing LUO Jianguo YANG Hangbing LV | 2023 | Science China(Information Sciences)2023，66，5： | 0 |
