| 1 | Microstructure and mechanical properties of CoCrNi-Mo medium entropy alloys:Experiments and first-principle calculations显示文摘The effect of Mo additions on the microstructures and mechanical properties of CoCrNi alloys was investigated,meanwhile,ab initio calculations are performed to quantitatively evaluate the lattice distortion and stacking fault energy(SFE).The yield strength,ultimate tensile strength,and elongation of(CoCrNi)_(97)Mo_(3)alloy are 475 MPa,983 MPa and 69%,respectively.The yield strength is increased by~30%and high ductility is maintained,in comparison with CoCrNi alloy.Besides the nano-twins and dislocations,the higher density of stacking faults is induced during the tensile deformation for(CoCrNi)_(97)Mo_(3)alloy.Ab initio calculation results indicate the mean square atomic displacement(MSAD)and SFE value of(CoCrNi)_(97)Mo_(3)alloy is 42.6 pm^(2)and-40.4 mJ/m^(2)at 0 K,respectively.The relationship between mechanical properties and MSAD,SFE for various multiple principal element alloys is discussed. | Ruobin Chang Wei Fang Jiaohui Yan Haoyang Yu Xi Bai Jia Li Shiying Wang Shijian Zheng Fuxing Yin | 2021 | Journal of Materials Science & Technology2021，，3： | 5 |
| 2 | Connecting Calcium-Based Nanomaterials and Cancer:From Diagnosis to Therapy显示文摘As the indispensable second cellular messenger,calcium signaling is involved in the regulation of almost all physiological processes by activating specific target proteins.The importance of calcium ions(Ca^(2+))makes its“Janus nature”strictly regulated by its concentration.Abnormal regulation of calcium signals may cause some diseases;however,artificial regulation of calcium homeostasis in local lesions may also play a therapeutic role.“Calcium overload,”for example,is characterized by excessive enrichment of intracellular Ca^(2+),which irreversibly switches calcium signaling from“positive regulation”to“reverse destruction,”leading to cell death.However,this undesirable death could be defined as“calcicoptosis”to offer a novel approach for cancer treatment.Indeed,Ca^(2+)is involved in various cancer diagnostic and therapeutic events,including calcium overload-induced calcium homeostasis disorder,calcium channels dysregulation,mitochondrial dysfunction,calcium-associated immunoregulation,cell/vascular/tumor calcification,and calcification-mediated CT imaging.In paral-lel,the development of multifunctional calcium-based nanomaterials(e.g.,calcium phosphate,calcium carbonate,calcium peroxide,and hydroxyapatite)is becoming abundantly available.This review will highlight the latest insights of the calcium-based nanomaterials,explain their application,and provide novel perspective.Identifying and characterizing new patterns of calcium-dependent signaling and exploiting the disease element linkage offer additional translational opportunities for cancer theranostics. | Shuang Bai Yulu Lan Shiying Fu Hongwei Cheng Zhixiang Lu Gang Liu | 2022 | Nano-Micro Letters2022，14，9： | 2 |
| 3 | Two-Dimensional Pnictogen for Field-Effect Transistors显示文摘Two-dimensional(2D)layered materials hold great promise for various future electronic and optoelectronic devices that traditional semiconductors cannot afford.2D pnictogen,group-VA atomic sheet(including phosphorene,arsenene,antimonene,and bismuthene)is believed to be a competitive candidate for next-generation logic devices.This is due to their intriguing physical and chemical properties,such as tunable midrange bandgap and controllable stability.Since the first black phosphorus fieldeffect transistor(FET)demo in 2014,there has been abundant exciting research advancement on the fundamental properties,preparation methods,and related electronic applications of 2D pnictogen.Herein,we review the recent progress in both material and device aspects of 2D pnictogen FETs.This includes a brief survey on the crystal structure,electronic properties and synthesis,or growth experiments.With more device orientation,this review emphasizes experimental fabrication,performance enhancing approaches,and configuration engineering of 2D pnictogen FETs.At the end,this review outlines current challenges and prospects for 2D pnictogen FETs as a potential platform for novel nanoelectronics. | Wenhan Zhou Jiayi Chen Pengxiang Bai Shiying Guo Shengli Zhang Xiufeng Song Li Tao Haibo Zeng | 2019 | Research2019，，1： | 1 |
| 4 | Advances in Research of Resources and Cultivation Techniques of Chinese Medicinal Material Radix Bupleuri显示文摘At present,with the vigorous development of traditional Chinese medicines,wild Bupleurum chinense resources become increasingly depleted,and its cultivars have become the mainstream of the market.However,due to factors such as a large number of original plants,irregular planting techniques,and poor growth environment,the quality of cultivated B.chinense is uneven and it is difficult to achieve the expected efficacy.In order to protect the wild resources of B.chinense and expand the source of medicinal materials,this paper summarized the research advances of the main resource producing areas and cultivation techniques of B.chinense in combination with relevant documents published at home and abroad,and discussed the future development of B.chinense,to provide a reference for research and sustainable development of B.chinense resources. | Ruyue BAI Xinyuan GAO Jinyue WEI Shiying TANG | 2021 | Medicinal Plant2021，12，4： | 1 |

| 6 | Electronic band structures and optical properties of atomically thin AuSe: first-principle calculations显示文摘As a large family of 2D materials, transition metal dichalcogenides(TMDs) have stimulated numerous works owing to their attractive properties. The replacement of constituent elements could promote the discovery and fabrication of new nanofilm in this family. Using precious metals, such as platinum and palladium, to serve as transition metals combined with chalcogen is a new approach to explore novel TMDs. Also, the proportion between transition metal and chalcogen atoms is found not only to exist in conventional form of 1 : 2. Herein, we reported a comprehensive study of a new 2D precious metal selenide, namely AuSe monolayer. Based on density functional theory, our result indicated that AuSe monolayer is a semiconductor with indirect band-gap of 2.0 eV, which possesses superior dynamic stability and thermodynamic stability with cohesive energy up to–7.87 eV/atom. Moreover, it has been confirmed that ionic bonding predominates in Au–Se bonds and absorption peaks in all directions distribute in the deep ultraviolet region. In addition, both vibration modes dominating marked Raman peaks are parallel to the 2D plane. | Pengxiang Bai Shiying Guo Shengli Zhang Hengze Qu Wenhan Zhou Haibo Zeng | 2019 | Journal of Semiconductors2019，40，6： | 0 |
| 7 | Contraction and warming of Antarctic Bottom Water in the Amundsen Sea显示文摘Antarctic Bottom Water(AABW)plays an important role in the meridional overturning circulation and contributes significantly to global heat transport and sea level rise(SLR).Based on the Global Ocean(1/12)°Physical Reanalysis(GLORYS12V1)products and conductivity-temperature-depth instrument data from the World Ocean Circulation Experiment hydrographic program,we analyzed the trends in the thickness,volume,temperature,salinity,and neutral density of the AABW in the Amundsen Sea from 1993 to 2017.Over the past 25 years,the volume has decreased by 3.45×10^(12) m^(3)/a,thinning at a rate of 5 m/a.In the vertical direction,the contraction of the AABW is compensated by the volume expansion of the Circumpolar Deep Water.As the volume of AABW decreases,the temperature of the AABW increases by about 0.002℃/a.This warming is equivalent to a heat flux of 0.27 W/m^(2).A local SLR is produced due to thermal expansion of 0.35 mm/a.During the study period,the neutral density decreased by 0.0003 kg/(m^(3)·a)due to warming.In the horizontal direction,the volume of AABW flowing from the Ross Sea into the Amundsen Sea gradually decreases and the temperature of the AABW increases continuously.The horizontal transport loss of the AABW volume is 4.07×10^(14) m^(3) and the horizontal heat transport results in a 0.03℃ increase in the temperature of the AABW. | Yu Bai Liang Zhao Jingen Xiao Shiying Lin | 2022 | Acta Oceanologica Sinica2022，41，4： | 0 |
