2AUTOMATED IMAGE MATCHING WITH CODED POINTS IN STEREOVISION MEASUREMENT显示文摘A coding-based method to solve the image matching problems in stereovision measure-ment is presented. The solution is to add and append an identity ID to the retro-reflect point, so it canbe identified efficiently under the complicated circumstances and has the characteristics of rotation,zooming, and deformation independence. Its design architecture and implementation process in de-tails based on the theory of stereovision measurement are described. The method is effective on re-ducing processing data time, improving accuracy of image matching and automation of measuringsystem through experiments.Dong Mingli Zhou Xiaogang Zhu Lianqing LU Naiguang Sun Yunan 2005Chinese Journal of Mechanical Engineering2005,18,3:1

4An efficient route to prepare suspended monolayer for feasible optical and electronic characterizations of two-dimensional materials显示文摘Two-dimensional(2D)materials are highly sensitive to substrates,interfaces,and the surrounding environments.Suspended 2D materials are free from substrate-induced effects,thus an ideal approach to study their intrinsic properties.However,it is very challenging to prepare large-area suspended 2D materials with high efficiency.Here we report a universal method,based on pretreatments of densely patterned hole array substrates with either oxygenplasma or gold film deposition,to prepare large-area suspended mono-and few-layer 2D materials.Multiple structural,optical,and electrical characterization tools were used to fully evaluate the improved performance of various suspended 2D layers.Some of these observations reported in this study are:(1)Observation of a new Raman low frequency mode for the suspended MoS_(2);(2)Significantly stronger photoluminescence(PL)and second harmonic generation(SHG)signals of suspended WSe_(2),which enables the study of new optical transition processes;(3)The low energy electron diffraction pattern on suspended MoS_(2) also exhibits much sharper spots than that on the supported area;and(4)The mobility of suspended graphene device approaches 300000 cm^(2) V^(-1) s^(-1),which is desirable to explore the intrinsic properties of graphene.This work provides an innovative and efficient route for fabricating suspended 2D materials,and we expect that it can be broadly used for studying intrinsic properties of 2D materials and in applications of hybrid active nanophotonic and electronic devices.Yuan Huang Yun-Kun Wang Xin-Yu Huang Guan-Hua Zhang Xu Han Yang Yang Yunan Gao Lei Meng Yushu Wang Guang-Zhou Geng Li-Wei Liu Lin Zhao Zhi-Hai Cheng Xin-Feng Liu Ze-Feng Ren Hui-Xia Yang Yufeng Hao Hong-Jun Gao Xing-Jiang Zhou Wei Ji Ye-Liang Wang 2022InfoMat2022,4,2:1
5The mechanism by which noncoding RNAs regulate muscle wasting in cancer cachexia显示文摘Cancer cachexia(CC)is a complex metabolic syndrome that accelerates muscle wasting and affects up to 80%of patients with cancer;however,timely diagnostic methods and effective cures are lacking.Although a considerable number of studies have focused on the mechanism of CC-induced muscle atrophy,few novel therapies have been applied in the last decade.In recent years,noncoding RNAs(ncRNAs)have attracted great attention as many differentially expressed ncRNAs in cancer cachectic muscles have been reported to participate in the inhibition of myogenesis and activation of proteolysis.In addition,extracellular vesicles(EVs),which function as ncRNA carriers in intercellular communication,are closely involved in changing ncRNA expression profiles in muscle and promoting the development of muscle wasting;thus,EV-related ncRNAs may represent potential therapeutic targets.This review comprehensively describes the process of ncRNA transmission through EVs and summarizes the pathways and targets of ncRNAs that lead to CC-induced muscle atrophy.Xueer Zhou Shoushan Hu Yunan Zhang Guannan Du Yi Li 2021Precision Clinical Medicine2021,4,2:0
6Phosphorus-doped lithium- and manganese-rich layered oxide cathode material for fast charging lithium-ion batteries显示文摘Owing to their high theoretical specific capacity and low cost, lithium- and manganese-rich layered oxide (LMR) cathode materials are receiving increasing attention for application in lithium-ion batteries. However, poor lithium ion and electron transport kinetics plus side effects of anion and cation redox reactions hamper power performance and stability of the LMRs. In this study, LMR Li_(1.2)Mn_(0.6)Ni_(0.2)O_(2) was modified by phosphorus (P)-doping to increase Li+ conductivity in the bulk material. This was achieved by increasing the interlayer spacing of the lithium layer, electron transport and structural stability, resulting in improvement of the rate and safety performance. P^(5+) doping increased the distance between the (003) crystal planes from ~0.474 nm to 0.488 nm and enhanced the structural stability by forming strong covalent bonds with oxygen atoms, resulting in an improved rate performance (capacity retention from 38% to 50% at 0.05 C to 5 C) and thermal stability (50% heat release compared with pristine material). First-principles calculations showed the P-doping makes the transfer of excited electrons from the valence band to conduction band easier and P can form a strong covalent bond helping to stabilize material structure. Furthermore, the solid-state electrolyte modified P5+ doped LMR showed an improved cycle performance for up to 200 cycles with capacity retention of 90.5% and enhanced initial coulombic efficiency from 68.5% (pristine) or 81.7% (P-doped LMR) to 88.7%.Yuqiong Kang Xingang Guo Zhiwu Guo Jiangang Li Yunan Zhou Zheng Liang Cuiping Han Xiangming He Yun Zhao Naser Tavajohi Baohua Li 2021Journal of Energy Chemistry2021,30,11:0
7Surplus energy utilization of spent lithium-ion batteries for high-profit organolithiums显示文摘It is challenging to efficiently and economically recycle many lithium-ion batteries(LIBs)because of the low valuation of commodity metals and materials,such as LiFePO_(4).There are millions of tons of spent LIBs where the barrier to recycling is economical,and to make recycling more feasible,it is required that the value of the processed recycled material exceeds the value of raw commodity materials.The presented research illustrates improved profitability and economics for recycling spent LIBs by utilizing the surplus energy in lithiated graphite to drive the preparation of organolithiums to add value to the recycled lithium materials.This study methodology demonstrates that the surplus energy of lithiated graphite obtained from spent LIBs can be utilized to prepare high-value organolithiums,thereby significantly improving the economic profitability of LIB recycling.Organolithiums(R-O-Li and R-Li)were prepared using alkyl alcohol(R-OH)and alkyl bromide(R-Br)as substrates,where R includes varying hindered alkyl hydrocarbons.The organolithiums extracted from per kilogram of recycled LIBs can increase the economic value between$29.5 and$226.5 kg^(−1) cell.The value of the organolithiums is at least 5.4 times the total theoretical value of spent materials,improving the profitability of recycling LIBs over traditional pyrometallurgical($0.86 kg^(−1) cell),hydrometallurgical($1.00 kg^(−1) cell),and physical direct recycling methods($5.40 kg^(−1) cell).Jian Lu Yun Zhao Yuqiong Kang Chenglei Li Yawen Liu Liguang Wang Hao Du Meicen Fan Yunan Zhou John Wozny Tao Li Naser Tavajohi Feiyu Kang Baohua Li 2023Carbon Energy2023,5,6:0
