| 2 | Joint synchronization estimation based on genetic algorithm for OFDM/OQAM systems显示文摘This paper investigates the problem of synchronization for offset quadrature amplitude modulation based orthogonal frequency division multiplexing(OFDM/OQAM) systems based on the genetic algorithm. In order to increase the spectrum efficiency,an improved preamble structure without guard symbols is derived at first. On this basis, instead of deriving the log likelihood function of power spectral density, joint estimation of the symbol timing offset and carrier frequency offset based on the preamble proposed is formulated into a bivariate optimization problem. After that, an improved genetic algorithm is used to find its global optimum solution. Conclusions can be drawn from simulation results that the proposed method has advantages in the joint estimation of synchronization. | LIU Yongjin CHEN Xihong ZHAO Yu | 2020 | Journal of Systems Engineering and Electronics2020，31，4： | 3 |
| 3 | Improving the Performance of Oilwell Cement by Graft-modifi ed PB Latex显示文摘Graft-modified polybutadiene(PB) latex was synthesized and used as an admixture to improve the performance of oilwell cement. Results showed that the addition of latex to pure cement slurry can significantly reduce the fluid loss of the cement slurry. When the dosage was 8%, the fluid loss was only 38 mL, and the fluidity of the cement slurry was improved. With an increasing amount of latex, the fluidity of the cement slurry increased continuously. The toughness of cement was significantly enhanced, whose average elastic modulus was 4.2 GPa. Scanning electron microscopy revealed that the filter cake of the cement slurry with latex was thin and dense, and the surface was coated with a layer of latex film. The microstructure of the cement stone showed a high density, and an interweaving mesh network formed in the cement. The results of cement hydration heat analysis and X-ray diffraction showed that latex inhibited the hydration of cement; the effect was stronger under a larger amount of latex. It is indicated that the graft-modified PB latex has great potential to replace the conventional styrene-butadiene rubber(SBR) latex for cementing in the future. | Jintang Guo Wenjie Pan Jinjie Fan Yongjin Yu | 2018 | Transactions of Tianjin University2018，24，5： | 2 |

| 8 | Screening neutral sites for metabolic engineering of methylotrophic yeast Ogataea polymorpha显示文摘Methylotrophic yeast Ogataea polymorpha is capable to utilize multiple carbon feedstocks especially methanol as sole carbon source and energy,making it an ideal host for bio-manufacturing.However,the lack of gene integration sites limits its systems metabolic engineering,in particular construction of genome-integrated pathway.We here screened the genomic neutral sites for gene integration without affecting cellular fitness,by genomic integration of an enhanced green fluorescent protein(eGFP)gene via CRISPR-Cas9 technique.After profiling the growth and fluorescent intensity in various media,17 genome positions were finally identified as potential neutral sites.Finally,integration of fatty alcohol synthetic pathway genes into neutral sites NS2 and NS3,enabled the production of 4.5 mg/L fatty alcohols,indicating that these neutral sites can be used for streamline metabolic engineering in O.polymorpha.We can anticipate that the neutral sites screening method described here can be easily adopted to other eukaryotes. | Wei Yu Jiaoqi Gao Xiaoxin Zhai Yongjin J.Zhou | 2021 | Synthetic and Systems Biotechnology2021，6，2： | 1 |

| 12 | Towards extreme fast charging of 4.6 V LiCoO_(2) via mitigating high-voltage kinetic hindrance显示文摘High-voltage LiCoO_(2)(LCO) is an attractive cathode for ultra-high energy density lithium-ion batteries(LIBs) in the 3 C markets.However,the sluggish lithium-ion diffusion at high voltage significantly hampers its rate capability.Herein,combining experiments with density functional theory(DFT) calculations,we demonstrate that the kinetic limitations can be mitigated by a facial Mg^(2+)+Gd^(3+)co-doping method.The as-prepared LCO shows significantly enhanced Li-ion diffusion mobility at high voltage,making more homogenous Li-ion de/intercalation at a high-rate charge/discharge process.The homogeneity enables the structural stability of LCO at a high-rate current density,inhibiting stress accumulation and irreversible phase transition.When used in combination with a Li metal anode,the doped LCO shows an extreme fast charging(XFC) capability,with a superior high capacity of 193.1 mAh g^(-1)even at the current density of 20 C and high-rate capacity retention of 91.3% after 100 cycles at 5 C.This work provides a new insight to prepare XFC high-voltage LCO cathode materials. | Yu Tang Jun Zhao He Zhu Jincan Ren Wei Wang Yongjin Fang Zhiyong Huang Zijia Yin Yalan Huang Binghao Zhang Tingting Yang Tianyi Li Leighanne CGallington Si Lan Yang Ren Qi Liu | 2023 | Journal of Energy Chemistry2023，，3： | 0 |
| 13 | Stabilized multifunctional phase change materials based on carbonized Cu-coated melamine foam/reduced graphene oxide framework for multiple energy conversion and storage显示文摘The leakage of organic phase change materials(OPCMs)at temperatures above their melting point severely limits their large-scale application.The introduction of porous supports has been identified as an efficient leakageproofing method.In this study,a novel carbonized Cu-coated melamine foam(MF)/reduced graphene oxide(rGO)framework(MF/rGO/Cu-C)is constructed as a support for fabricating stabilized multifunctional OPCMs.MF serves as the supporting material,while rGO and Cu act as functional reinforcements.As a thermal energy storage material,polyethylene glycol(PEG)is encapsulated into MF/rGO/Cu-C through a vacuum-assisted impregnation method to obtain PEG@MF/rGO/Cu-C composite with excellent comprehensive performance.PEG@MF/rGO/Cu-C exhibits high phase change enthalpies of 148.3 J g^(-1)(melting)and 143.9 J g^(-1)(crystallization),corresponding to a high energy storage capability of 92.7%.Simultaneously,MF/rGO/Cu-C endues the composite with an enhanced thermal conductivity of 0.4621Wm^(-1) K^(-1),which increases by 463%compared to that of PEG@MF.Furthermore,PEG@MF/rGO/Cu-C displays great light-to-thermal and electric-to-thermal conversion capabilities,thermal cycle stability,light-tothermal cycle stability,and shape stability,showing promising application prospects in different aspects. | Zhicong Hu Yongjin Zou Cuili Xiang Lixian Sun Fen Xu Menghe Jiang Sensen Yu | 2022 | Carbon Energy2022，4，6： | 0 |
| 14 | Bifunctional interstitial phosphorous doping strategy boosts platinum-zinc alloy for efficient ammonia oxidation reaction and hydrogen evolution reaction显示文摘It is still a lack of bifunctional catalysts for ammonia oxidation reaction(AOR)and hydrogen evolution reaction(HER)due to their different reaction mechanisms.In this work,P is doped into PtZn alloy by calcination with NaH_(2)PO_(2) as P source to induce the lattice tensile strain of Pt and the electronic interaction between P and Zn,which optimizes the AOR and HER activity simultaneously.The sample with the optimal P content can drive the AOR peak current density of 293.6 mA·mgPt^(-1),which is almost 2.7 times of Pt.For HER,the overpotential at^(-1)0 mA·cm^(-2) is only 23 mV with Tafel slope of 34.1 mV·dec^(-1).Furthermore,only 0.59 V is needed to obtain 50 mA·mgPt^(-1) for ammonia electrolysis under a two-electrode system.Therefore,this work shows an ingenious method to design bifunctional catalysts for ammonia electrolysis. | Tianqi Yu Kexin Tan Jia Wu Yongjin Zou Shibin Yin | 2024 | Nano Research2024，17，3： | 0 |
| 15 | Characterizing and engineering promoters for metabolic engineering of Ogataea polymorpha显示文摘Bio-manufacturing via microbial cell factory requires large promoter library for fine-tuned metabolic engi-neering.Ogataea polymorpha,one of the methylotrophic yeasts,possesses advantages in broad substrate spec-trum,thermal-tolerance,and capacity to achieve high-density fermentation.However,a limited number of available promoters hinders the engineering of O.polymorpha for bio-productions.Here,we systematically characterized native promoters in O.polymorpha by both GFP fluorescence and fatty alcohol biosynthesis.Ten constitutive promoters(P_(PDH),P_(PYK),P_(FBA),P_(PGM),P_(GLK),P_(TRI),P(GPI),P_(ADH1),P_(TEF1) and P_(GCW14))were obtained with the activity range of 13%–130% of the common promoter P_(GAP)(the promoter of glyceraldehyde-3-phosphate de-hydrogenase),among which P_(PDH) and P_(GCW14) were further verified by biosynthesis of fatty alcohol.Furthermore,the inducible promoters,including ethanol-induced P_(ICL1),rhamnose-induced P_(LRA3) and P_( LRA4),and a bidirectional promoter(P_(Mal)-P_(Per))that is strongly induced by sucrose,further expanded the promoter toolbox in O.polymorpha.Finally,a series of hybrid promoters were constructed via engineering upstream activation sequence(UAS),which increased the activity of native promoter P LRA3 by 4.7–10.4 times without obvious leakage expression.Therefore,this study provided a group of constitutive,inducible,and hybrid promoters for metabolic engineering of O.polymorpha,and also a feasible strategy for rationally regulating the promoter strength. | Chunxiao Yan Wei Yu Xiaoxin Zhai Lun Yao Xiaoyu Guo Jiaoqi Gao Yongjin J.Zhou | 2022 | Synthetic and Systems Biotechnology2022，7，1： | 0 |
| 16 | Tectonic-lithofacies paleogeography,large-scale source-reservoir distribution and exploration zones of Cambrian subsalt formation,Tarim Basin,NW China显示文摘To predict the large-scale source rock and reservoir distribution in Cambrian subsalt formations(Upper Sinian to Mid-Cambrian)in the Tarim Basin,more than 502D seismic lines and 3D data volume acquired latest,22 wells and some out-crops around this area were used to study the tectonic-lithofacies paleogeography,define the distribution of large scale source rocks and reservoirs,and sort out favorable zones.(1)The basin experienced evolution from ramp to deep-water mud-rich ramp,low-gradient slope,weak rimmed to strong rimmed platform,and the differentiation in the platform was controlled by pre-Cambrian palaeo-rifts.(2)The Luonan-Yubei ancient rift controlled the distribution of source rocks in the Lower Cambrian Yuertusi Formation,and this rift together with the northern depression are the main source rock area.(3)There are three sets of large-scale reservoirs,the Upper Sinian Qigebulake Formation,the Lower Cambrian Xiaorbulake Formation and the Wu-songger Formation,and shoal-mounds,early dolomitization and multi-levels of unconformities controlled reservoir develop-ment.(4)Four favorable zones,the north slope of Tazhong,upper slope of Maigaiti area,Keping-Wensu periphery,and south slope of Tabei,were evaluated.Of them,the north slope of Tazhong is most likely to have exploration breakthrough;the south slope of Tabei is the best area for exploring the Upper Sinian large scale weathering crust dolomite;Maigaiti slope and Kep-ing-Wensu periphery area improved in exploration potentials significantly,and are worth prospecting faster. | WEI Guoqi ZHU Yongjin ZHENG Jianfeng YU Guang NI Xinfeng YAN Lei TIAN Lei HUANG Lili | 2021 | Petroleum Exploration and Development2021，48，6： | 0 |
| 17 | Mitochondrial diseases and mtDNA editing显示文摘Mitochondrial diseases are a heterogeneous group of inherited disorders character-ized by mitochondrial dysfunction,and these diseases are often severe or even fatal.Mito-chondrial diseases are often caused by mitochondrial DNA mutations.Currently,there is no curative treatment for patients with pathogenic mitochondrial DNA mutations.With the rapid development of traditional gene editing technologies,such as zinc finger nucleases and tran-scription activator-like effector nucleases methods,there has been a search for a mitochon-drial gene editing technology that can edit mutated mitochondrial DNA;however,there are still some problems hindering the application of these methods.The discovery of the DddA-derived cytosine base editor has provided hope for mitochondrial gene editing.In this paper,we will review the progress in the research on several mitochondrial gene editing technologies with the hope that this review will be useful for further research on mitochondrial gene editing technologies to optimize the treatment of mitochondrial diseases in the future. | Min Song Lingqun Ye Yongjin Yan Xuechun Li Xinglong Han Shijun Hu Miao Yu | 2024 | Genes & Diseases2024，11，3： | 0 |
