| 1 | Geomicrobial functional groups:A window on the interaction between life and environments显示文摘Microbes are well-known for their great diversity and abundance in modern natural environments.They also are believed to pro-vide critical links among higher organisms and their associated environments.However,the low diversity of morphological fea-tures and structures of ancient microbes preserved in sediments and rocks make them difficult to identify and classify.This diffi-culty greatly hinders the investigation of geomicrobes throughout Earth history.Thus,most previous paleontological studies have focused on faunal and floral fossils.Here,geomicrobial functional groups(GFGs),or a collection of microbes featured in specific ecological,physiological or biogeochemical functions,are suggested to provide a way to overcome the difficulties of ancient mi-crobe investigations.GFGs are known for their great diversity in ecological,physiological and biogeochemical functions.In addi-tion,GFGs may be preserved as the biogeochemical,mineralogical and sedimentological records in sediments and rocks.We reviewed the functions,origins and identification diagnostics of some important GFGs involved in the elemental cycles of carbon,sulfur,nitrogen and iron.GFGs were further discussed with respect to their significant impacts on paleoclimate,sulfur chemistry of ancient seawater,nutritional status of geological environments,and the deposition of Precambrian banded iron formations. | XIE ShuCheng YANG Huan LUO GenMing HUANG XianYu LIU Deng WANG YongBiao GONG YiMing XU Rana | 2012 | Chinese Science Bulletin2012，57，1： | 11 |
| 2 | Microbial influences on paleoenvironmental changes during the Permian-Triassic boundary crisis显示文摘The biosphere interacts and co-evolves with natural environments.Much is known about the biosphere’s response to ancient environmental perturbations,but less about the biosphere’s influences on environmental change through earth history.Here,we discuss the roles of microbes in environmental changes during the critical Permian-Triassic(P-Tr)transition and present a perspective on future geomicrobiological investigations.Lipid biomarkers,stable isotopic compositions of carbon,nitrogen and sulfur,and mineralogical investigations have shown that a series of microbial functional groups might have flourished during the P-Tr transition,including those capable of sulfate reduction,anaerobic H2S oxidation,methanogenesis,aerobic CH4oxidation,denitrification,and nitrogen fixation.These microbes may have served to both enhance and degrade the habitability of the Earth-surface environment during this crisis.The integrated microbial roles have enabled the Earth’s exosphere to be a self-regulating system. | LUO GenMing XIE ShuCheng LIU Deng Thomas J.

| 4 | Microbes in mass extinction: an accomplice or a savior?显示文摘Microbes include various types of organisms that are invisible to the naked eye,e.g. bacteria, archaea and microeukaryotes. Although the precise number remains largely unknown, microbes are recognized as the unseen majority of our biosphere [1]. As a group of organisms classified by body size, microbes cover a considerable spectrum of metabolisms. | Genming Luo Deng Liu Hao Yang | 2024 | National Science Review2024，11，1： | 0 |
| 5 | Improved Quark-Meson Model显示文摘Since the conjecture of Witten that strange quark matter (SQM) would be more stable than the normal nuclear matterin is got, much theoretical effort has been directed toward the investigation of its properties and applications.Many effective models reflecting the characteristics of the strong interaction are used to study the SQM. They include the MIT bag model,the quark meson coupling(QMO) model, | Li Xiguo, Guo Yanrui, Liu Ziyu and Jin Genming | 2005 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2005，，1： | 0 |
| 6 | Novel attitude determination method by integration of electronic level meter,INS,and low-cost turntable for level attitude evaluation and calibration of INS显示文摘Attitude references are greatly needed for the evaluation and calibration of Inertial Navigation Systems(INSs),which are widely used in gravimeter,marine,and aeronautical navigation.High-accuracy turntable,INS,and Global Navigation Satellite System have been utilized to verify the performance of relatively low-accuracy INS.The accuracy requirement of the attitude reference continuously increases with the rapid improvement of inertial sensors and navigation algorithms.However,the cost of attitude determination system increases rapidly with the increase of attitude accuracy requirement.To solve this limitation,the integration of level meter,INS,and low-cost turntable is proposed to provide level attitude,such as roll and pitch.The turntable is utilized to rotate the INS.An integration model of the level meter and INS is built to estimate the level attitude and reduce the cost of the turntable.The proposed method successfully avoids the dependence on high-accuracy turntables.An observability degree analysis is conducted to improve the level atti-tude accuracy further.The simulation and turntable test results indicate that the proposed method can provide high-accuracy level attitude without high-accuracy INS or turntable and is applicable to error calibration and attitude evaluation of INS. | Anlan YANG Peida HU Genming LIU Rong ZHANG Qiuping WU Ruikun ZHOU | 2023 | Chinese Journal of Aeronautics2023，36，4： | 0 |
| 7 | The mechanism of external pressure suppressing dendrites growth in Li metal batteries显示文摘Li metal is considered an ideal anode material for application in the next-generation secondary batteries.However,the commercial application of Li metal batteries has not yet been achieved due to the safety concern caused by Li dendrites growth.Despite the fact that many recent experimental studies found that external pressure suppresses the Li dendrites growth,the mechanism of the external pressure effect on Li dendrites remains poorly understood on the atomic scale.Herein,the large-scale molecular dynamics simulations of Li dendrites growth under different external pressure were performed with a machine learning potential,which has the quantum-mechanical accuracy.The simulation results reveal that the external pressure promotes the process of Li self-healing.With the increase of external pressure,the hole defects and Li dendrites would gradually fuse and disappear.This work provides a new perspective for understanding the mechanism for the impact of external pressure on Li dendrites. | Genming Lai Yunxing Zuo Junyu Jiao Chi Fang Qinghua Liu Fan Zhang Yao Jiang Liyuan Sheng Bo Xu Chuying Ouyang Jiaxin Zheng | 2023 | Journal of Energy Chemistry2023，，4： | 0 |

| 11 | Microbially-mediated formation of Ca-Fe carbonates during dissimilatory ferrihydrite reduction:Implications for the origin of sedimentary ankerite显示文摘The origin of sedimentary dolomite has become a long-standing problem in the Earth Sciences.Some carbonate minerals like ankerite have the same crystal structure as dolomite,hence their genesis may provide clues to help solving the dolomite problem.The purpose of this study was to probe whether microbial activity can be involved in the formation of ankerite.Bio-carbonation experiments associated with microbial iron reduction were performed in batch systems with various concentrations of Ca^(2+)(0–20 mmol/L),with a marine iron-reducing bacterium Shewanella piezotolerans WP3 as the reaction mediator,and with lactate and ferrihydrite as the respective electron donor and acceptor.Our biomineralization data showed that Ca-amendments expedited microbially-mediated ferrihydrite reduction by enhancing the adhesion between WP3 cells and ferrihydrite particles.After bioreduction,siderite occurred as the principal secondary mineral in the Ca-free systems.Instead,Ca-Fe carbonates were formed when Ca^(2+)ions were present.The CaCO_(3) content of microbially-induced Ca-Fe carbonates was positively correlated with the initial Ca2+concentration.The Ca-Fe carbonate phase produced in the 20 mmol/L Ca-amended biosystems had a chemical formula of Ca_(0.8)Fe_(1.2)(CO_(3))_(2),which is close to the theoretical composition of ankerite.This ankeritelike phase was nanometric in size and spherical,Ca-Fe disordered,and structurally defective.Our simulated diagenesis experiments further demonstrated that the resulting ankerite-like phase could be converted into ordered ankerite under hydrothermal conditions.We introduced the term“proto-ankerite”to define the Ca-Fe phases that possess near-ankerite stoichiometry but disordered cation arrangement.On the basis of the present study,we proposed herein that microbial activity is an important contributor to the genesis of sedimentary ankerite by providing the metastable Ca-Fe carbonate precursors. | Deng LIU Jinpeng CAO Shanshan YANG Yating YIN Pengcong WANG Dominic PAPINEAU Hongmei WANG Xuan QIU Genming LUO Zongmin ZHU Fengping WANG | 2024 | Science China Earth Sciences2024，67，1： | 0 |
