| 1 | Improved Plasticity and Cold-rolling Workability of Fe–6.5wt%Si Alloy by Warm-rolling with Gradually Decreasing Temperature显示文摘The effects of warm-rolling process on the microstructure,ordering,mechanical properties and coldrolling workability of Fe–6.5wt%Si alloy were investigated,where three processes of warm-rolling with the same total reduction of 93% were used,including(1)500°C/12 passes/total reduction of 93%,(2)500°C/3passes/total reduction of 50%+400°C/9 passes/total reduction of 86%,and (3)500°C/3 passes/total reduction of 50%+400°C/5 passes/total reduction of 60%+300°C/4 passes/total reduction of 64%.The results show that compared with process (1) warm-rolling with constant temperature of 500°C,process(2) and process (3) warm-rolling with gradually decreasing temperature can signi?cantly improve the room temperature plasticity and cold-rolling workability of the Fe–6.5wt%Si alloy.For example,the three point bending fracture deflections are increased by 54.5% and 81.8% for processes (2) and (3),respectively,and the maximum reductions of single pass cold-rolling without edge crack are increased from 50% of process(1)to 55% of process (2) and 62% of process(3),respectively.The plasticity improvement of the Fe–6.5wt%Si alloy can be attributed to both reductions of surface oxidation degree and order degree of the alloy by warm-rolling with gradually decreasing temperature. | Yuanke Mo Zhihao Zhang Hongjiang Pan Jianxin Xie | 2016 | Journal of Materials Science & Technology2016，32，5： | 3 |

| 10 | Engineering the native methylotrophs for the bioconversion of methanol to value-added chemicals:current status and future perspectives显示文摘Methanol is becoming an attractive fermentation feedstock for large-scale bioproduction of chemicals,due to its natural abundance and mature production technology.Native methylotrophs,which can utilize methanol as the only source of carbon and energy,are ideal hosts for methanol bioconversion due to their high methanol utili-zation rate and have been extensively employed in the production of value-added chemicals from methanol.Here,we review the natural methanol utilization pathways in native methylotrophs,describing the available synthetic biology tools developed for engineering native methylotrophs,and discuss the strategies for improving their methanol utilization efficiency.Finally,the representative examples of engineering the native methylotrophs to produce value-added products from methanol are summarized.Furthermore,we also discuss the major challenges and possible solutions for the application of native methylotrophs in methanol-based biomanufacturing. | Jing Wang Ruirui Qin Yuanke Guo Chen Ma Xin Wang Kequan Chen Pingkai Ouyang | 2023 | Green Chemical Engineering2023，4，2： | 0 |
| 11 | Cryo-CMOS modeling and a 600 MHzcryogenic clock generator for quantumcomputing applications显示文摘The development of large-scale quantum computing has boosted anurgent desire for the advancement of cryogenic CMOS(cryo-CMOS),which is a promising scalable solution for the control and read-out interface of quantum bits.In the current work,180 nm CMOS transistors were characterized and modeled down to 4 K,and the impact oflow-temperature transistor performance variations on circuit designwas also analyzed.Based on the proposed cryogenic model,a 180 nmCMOS-based 450 to 850 MHz clock generator operating at 4 K forquantum computing applications was presented.At the output frequency of 600 MHz,it achieved<4.8 ps RMS jitter with 30 mWpower consumption(with test buffer),corresponding to a−211.6 dBjitter-power FOM,which is suitable for providing a stable clock signalfor the control and readout electronics of scalable quantum computers. | Qiwen Xue Yuanke Zhang Mingjie Wen Xiaohu Zhai Yuefeng Chen Tengteng Lu Chao Luo Guoping Guo | 2023 | Chip2023，2，4： | 0 |
| 12 | Frost Resistance of Magnesium Oxychloride Cement Mortar Added with Highland Barley Straw Ash显示文摘In order to study the influence of highland barley straw ash (HBSA) prepared under certain conditions on the durability of magnesium oxychloride cement mortar (MOCM) under freeze-thaw damage,rapid freeze-thaw cycle tests were carried out firstly.The relative mass evaluation parameters and the relative compressive strength evaluation parameters,which represent the degradation of freeze-thaw resistance,were used as the indices to study the degradation rule of MOCM.Secondly,nuclear magnetic resonance (NMR) tests were carried out on MOCM under different freeze-thaw cycles to analyze the pore diameter changes in the freeze-thaw process.The microstructure of MOCM was tested by Fourier transform infrared spectroscopy (FTIR),X-ray diffraction (XRD) and scanning electron microscopy (SEM),and then the effect mechanism of HBSA on the anti-freezing performance of MOCM was revealed.Finally,the two-parameter Weibull distribution function was used to analyze the reliability of durability degradation of MOCM added with HBSA under freeze-thaw cycles.The specific conclusions are as follows:With the increase of HBSA's addition,the freeze-thaw resistance of MOCM increase firstly and then decrease.When the addition of HBSA is 10%,the decay rate of relative mass evaluation parameters and relative compressive strength evaluation parameters is the slowest,and the frost resistance is the best.The proportion of harmful pores and more harmful pores in MOCM added with 10% HBSA decreases by 25.11% and 21.34%,compared with that without HBSA before and after freeze-thaw cycles.A lot of magnesium silicate hydrate (M-S-H) gels are generated in MOCM with HBSA content of 10%,which fills part of the pores,so that the proportion of harmful pores and more harmful pores is the lowest.The Weibull function can be effectively applied to the reliability analysis of the freeze-thaw cycle of MOCM added with HBSA,and the theoretical results are in good agreement with the experimental results. | 曹锋 乔宏霞 WANG Penghui LI Weijia LI Yuanke | 2022 | Journal of Wuhan University of Technology(Materials Science)2022，37，5： | 0 |
| 13 | Development Optimization for a Typical Carbonate Reservoir in the Middle East显示文摘Belt and Road initiative is a very important strategy for Chinese companies to cooperate with foreign ones.The Middle East is a region that contains abundant oil and gas resources. Meanwhile, many countries in the Middle East support and join in the Belt and Road initiative. Since oil and gas resources are of vital significance for Chinese industry,the cooperation in oil and gas with countries in the Middle East is an important part in 'Belt and Road' initiative. CNPC began its overseas business from the year 1993 and now it keeps cooperating with many countries in the Middle East. UAE has a large amount of oil and gas reserves and after evaluation, CNPC became the shareholder of ADNOC Onshore and gained 8% of the stocks.In order to improve the development effect, ADNOC appointed several international oil companies as asset leaders for four assets. As a reward, each asset leader can have more income and less tax. As a result, CNPC decided to compete for NEB asset leader with other international oil companies. After analyzing the current development plan, our group conducted the optimization scheme for NEB asset that can help improve the current situation and enhance oil recovery.The optimization scheme is divided into three steps. First is the establishment of effective drainage system.Second is to control water cut and GOR. Third is to enhance oil recovery factor based on first two steps. After discussion with the research group of ADNOC, they admitted that our strategy can solve the problems. Finally, CNPC obtained the asset leader, and has more impact on UAE oil and gas industry since then. | Wei Chenji Yang Jian Liu Shuangshuang Li Zhengzhong Lou Yuankeli | 2019 | China Oil & Gas2019，26，1： | 0 |
| 14 | High-safety and high-voltage lithium metal batteries enabled by nonflammable diluted highly concentrated electrolyte显示文摘Lithium metal batteries(LMBs)show great promise for achieving energy densities over 400 Wh·kg^(-1).However,highly flammable organic electrolytes are a long-lasting problem that triggers safety hazards and hinders the commercial application of LMBs.Here,a nonflammable diluted highly concentrated electrolyte(DHCE)with ethoxy(pentafluoro)cyclotriphosphazene(PFPN)as a diluent is developed to simultaneously achieve high safety and cycling stability of high-voltage LMBs.The optimal DHCE not only ensures reversible Li deposition/dissolution behavior with a superior average Coulombic efficiency(CE)over 99.1%on lithium metal anode(LMA),but also suppresses side reactions and stress crack on the LiCoO_(2)(LCO)under high cut-off voltage.The newly developed DHCE exhibits high thermal stability,showing complete nonflammability and reduced heat generation between the electrolyte and delithiated LCO/cycled LMA.This work offers an opportunity for rational designing nonflammable electrolytes toward high-voltage and safe LMBs. | Han Zhang Ziqi Zeng Shuping Wang Yuanke Wu Changhao Li Mengchuang Liu Xinlan Wang Shijie Cheng Jia Xie | 2024 | Nano Research2024，17，4： | 0 |
| 15 | The Feasibility of Basalt Rock Powder and Superfine Sand as Partial Replacement Materials for Portland Cement and Artificial Sand in Cement Mortar显示文摘The research gap on the feasibility of basalt rock powder(BRP)and superfine sand(SS)in preparation of cement mortar is significant.This study examines probable changes occurred in the modified cement mortar due to incorporation of certain quantity of basalt rock powder and superfine sand in mixture proportion.The cement mortar included Portland cement,artificial sand and water as principal mixture constituents.Then,basalt rock powder and superfine sand were added as partial replacement materials for Portland cement and artificial sand respectively.Therefore,replacement percentages were 10%,15%,20%,25%and 30%when the basalt rock powder replaced Portland cement and in case the artificial sand was replaced by superfine sand,10%,20%,30%,40%and 50%.Then,the strength indexes such as flexural strength,compressive strength,ultrasonic pulse velocity and dynamic elastic modulus were investigated.The results show that the presence of basalt rock powder in mixture proportion increased the flexural and compressive strengths of cement mortar however the cement mortar that contained superfine sand illustrated inadequate mechanical performance as flexural and compressive strengths decreased remarkably.Moreover,when basalt rock powder and superfine sand were included together in mixture proportion,the cement mortar’s mechanical performance declined compared to that of the reference cement mortar.Despite the fact that basalt rock powder and superfine sand weakened the cement mortar’s mechanical properties,it was found that they can be added into the cement mortar as partial replacement of Portland cement and artificial sand in the following ratios:from 10%to 25%when basalt rock powder replaces Portland cement and from 10%to 20%when artificial sand is replaced by superfine sand. | Hongxia Qiao Desire Ndahirwa Yuanke Li Jinke Liang | 2019 | Research and Application of Materials Science2019，1，1： | 0 |
| 16 | “In-N-out” design enabling high-content triethyl phosphate-based non-flammable and high-conductivity electrolytes for lithium-ion batteries显示文摘Safety issues related to flammable electrolytes in lithium-ion batteries(LIBs) remain a major challenge for their extended applications.The use of non-flammable phosphate-based electrolytes has proved the validity in inhibiting the combustion of LIBs.However,the strong interaction between Li^(+) and phosphate leads to a dominant solid electrolyte interphase(SEI) with limited electronic shielding,resulting in the poor Li^(+) intercalation at the graphite(Gr) anode when using high-phosphate-content electrolytes.To mitigate this issue and improve Li^(+) insertion,we propose an “In-N-Out” strategy to render phosphates “noncoordinative”.By employing a combination of strongly polar solvents for a “block effect” and weakly polar solvents for a “drag effect”,we reduce the Li^(+)–phosphate interaction.As a result,phosphates remain in the electrolyte phase(“In”),minimizing their impact on the incompatibility with the Gr electrode(“Out”).We have developed a non-flammable electrolyte with high triethyl phosphate(TEP) content(>60 wt.%),demonstrating the excellent ion conductivity(5.94 mS cm^(-1) at 30 ℃) and reversible Li^(+) intercalation at a standard concentration(~1 mol L^(-1)).This approach enables the manipulation of multiple electrolyte functions and holds the promise for the development of safe electrochemical energy storage systems using non-flammable electrolytes. | Mengchuang Liu Fenfen Ma Zicheng Ge Ziqi Zeng Qiang Wu Hui Yan Yuanke Wu Sheng Lei Yanli Zhu Shijie Cheng Jia Xie | 2024 | Science China Chemistry2024，67，2： | 0 |
| 17 | Characterization and application of a recombinant dopa decarboxylase from Harmonia axyridis for the efficient biosynthesis of dopamine显示文摘Here,a dopa decarboxylase(DDC)from Harmonia axyridis was heterogeneously expressed in Escherichia coli for the efficient biosynthesis of dopamine.For the production of recombinant DDC,the cultivation conditions including IPTG concentration,temperature and induction time were optimized and obtained an optimal specific enzyme activity of 51.72 U·mg^(-1) crude extracts.After the purification of DDC with a recovery yield of 68.79%,its activity was further characterized.The Vmax,Km,Kcat,and Kcat/Km of DDC for d ihyd roxy pheny la la nine(dopa)were 0.02 mmol·ml^(-1)·s^(-1),2.328 mmol·ml^(-1),10435.90 s^(-1) and4482.77 ml,mmol respectively.The highest DDC activity was observed at the condition of pH 7.5 and 45℃.With the purified DDC,the feasibility to produce dopamine from L-dopa was evaluated.The optimal yield was determined at the following bioconversion conditions:pH of 7,0,the reaction temperature of 40℃,0.4 mmol·L^(-1) of PLP and 4 g·L^(-1) of L-dopa,Subsequently,a fed-batch process for the production of dopamine was developed and the effect of oxygen was evaluated.The titer,yield and productivity of dopamine reached up to 21.99 g·L^(-1)80.88%and 14.66 g·L^(-1)·h^(-1) at 90 min under anaerobic condition. | Siyuan Gao Yuanke Guo Chen Ma Ding Ma Kequan Chen Pingkai Ouyang Xin Wang | 2022 | Chinese Journal of Chemical Engineering2022，35，1： | 0 |
