| 1 | Integrated Energy System Planning at Modular Regional-user Level Based on a Two-layer Bus Structure显示文摘An integrated energy system(IES)planning method with modular simulation and optimization models is proposed in this paper.A two-layer bus structure is adopted in the simulation model,where the external bus structure is used for power balance while the internal bus structure simulates the fast dynamics of electricity and slow dynamics of heat network in detail.In addition,an improved self-adaptive genetic algorithm(GA)is adopted in the optimization model to solve the multi-dimension and multi-time-scales optimization problem for the regional-user level IEPS.The proposed method can improve the extension flexibility of the system optimal planning model with expected accuracy.A case study is used to verify the effectiveness of the proposed planning method. | Bowen Hong Jian Chen Weitong Zhang Zhiyong Shi Junjie Li Weiwei Miao | 2018 | CSEE Journal of Power and Energy Systems2018，4，2： | 8 |
| 2 | Loss of FOXC1 contributes to the corneal epithelial fate switch and pathogenesis显示文摘Forkhead box C1(FOXC1)is required for neural crest and ocular development,and mutations in FOXC1 lead to inherited Axenfeld-Rieger syndrome.Here,we find that FOXC1 and paired box 6(PAX6)are co-expressed in the human limbus and central corneal epithelium.Deficiency of FOXC1 and alternation in epithelial features occur in patients with corneal ulcers.FOXC1 governs the fate of the corneal epithelium by directly binding to lineage-specific open promoters or enhancers marked by H3K4me2.FOXC1 depletion not only activates the keratinization pathway and reprograms corneal epithelial cells into skin-like epithelial cells,but also disrupts the collagen metabolic process and interferon signaling pathways.Loss of interferon regulatory factor 1 and PAX6 induced by FOXC1 dysfunction is linked to the corneal ulcer.Collectively,our results reveal a FOXC1.mediated regulatory network responsible for corneal epithelial homeostasis and provide a potential therapeutic target for corneal ulcer. | Mingsen Li Liqiong Zhu Jiafeng Liu Huaxing Huang Huizhen Guo Li Wang Lingyu Li Sijie Gu Jieying Tan Jing Zhong Bowen Wang Zhen Mao Yong Fan Chunqiao Liu Jin Yuan Hong Ouyang | 2021 | Signal Transduction and Targeted Therapy2021，6，2： | 2 |
| 3 | D609 protects retinal pigmented epithelium as a potential therapy for age-related macular degeneration显示文摘Accumulated oxidative damage may lead to irreversible retinal pigmented epithelium(RPE)cell death,which is considered to be the primary cause of dry age-related macular degeneration(AMD),leading to blindness in the elderly.However,an effective therapy for this disease is lacking.Here,we described a robust high-content screening procedure with a library of 814 protective compounds and found that D609 strongly protected RPE cells from sodium iodate(SI)-induced oxidative cell death and prolonged their healthy survival.D609 effectively attenuated excessive reactive oxygen species(ROS)and prevented severe mitochondrial loss due to oxidative stress in the RPE cells.Surprisingly,the potent antioxidative effects of D609 were not achieved through its own reducibility but were primarily dependent on its ability to increase the expression of metallothionein.The injection of this small water-soluble molecule also showed an explicit protective effect of the RPE layer in an SI-induced AMD mouse model.These findings suggested that D609 could serve as a novel antioxidative protector of RPE cells both in vitro and in vivo and unveiled a novel antioxidative mechanism of D609,which may ultimately have clinical applications for the treatment of AMD. | Bowen Wang Li Wang Sijie Gu Yankun Yu Huaxing Huang Kunlun Mo He Xu Fanzhu Zeng Yichen Xiao Lulu Peng Chunqiao Liu Nan Cao Yizhi Liu Jin Yuan Hong Ouyang | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 2 |

| 5 | 增温和放牧对高寒草甸凋落物分解及其养分释放的影响不依赖于凋落物品质显示文摘在放牧生态系统中,增温、放牧和调落物品质共同决定着凋落物分解和养分释放。然而,在以往的研究中这些因子的效应通常被单独地研究。在本研究中,我们在青藏高原高寒草甸开展了一个昼夜非对称增温和中度放牧两因子的调落物分解试验。从每个处理中收集了调落物样品,这些调落物一部分放在它们的来源处理小区,另一部分放在其他处理小区以此来探究增温、放牧以及调落物品质对调落物分解和养分释放的影响。研究结果表明,增温而不是放牧显著增加了调落物质量的损失、单位面积全碳、全氮以及全磷含量的损失,这主要是因为增温增加了落物生物量和分解速率。然而,尽管同时增温放牧处理也加快了调落物分解速率,但由于降低了调落物生物量,所以增温放牧处理并没有显著影响单位面积的凋落物碳和养分释放量。相比木质素含量和碳氮比而言,季节性土壤平均温度能够更好地预测调落物分解速率。增温和放牧对调落物分解存在交互作用,但它们和调落物品质对调落物的影响均不存在交互作用。单位面积的总氮释放的温度敏感性要高于总磷。因此,我们的结果表明,增温对调落物分解以及养分释放的影响要显著大于调落物品质变化对其分解的影响。在高寒草甸,氮释放的增加可能会间接导致土壤磷有效性的缺乏。 | Bowen Li Wangwang Lv Jianping Sun Lirong Zhang Lili Jiang Yang Zhou Peipei Liu Huan Hong Qi Wang Wang A Suren Zhang Lu Xia Zongsong Wang Tsechoe Dorji Ailing Su Caiyun Luo Zhenhua Zhang Shiping Wang | 2022 | Journal of Plant Ecology2022，15，5： | 1 |
| 6 | Effects of SNPs and alternative splicing within HGF gene on its expression patterns in Qinchuan cattle显示文摘Background: Identification of genetic variants, including SNPs(Single Nucleotide Polymorphisms), CNVs(Copy Number Variations) and alternative splicing, within functional genes has received increasing attention in animal science research. HGF(Hepatocyte Growth Factor) is a very important growth factor that works as a mitogen or a morphogen during tissue growth, development and regeneration. However, to date, the functions of genetic variants within the bovine HGF gene, particularly their effects on m RNA expression, have not been determined well.Results: The present study aimed to perform association analysis between genetic variants and m RNA expression for the bovine HGF gene in Qinchuan cattle using various strategies, including PCR-RFLP(Restriction Fragment Length Polymorphism), q PCR(Quantitative Real-time quantitative PCR), TA cloning, DNA sequencing and bioinformatics analysis. A total of five SNPs were identified and only SV1 locus significantly affected HGF m RNA expression in fetal skeletal muscle(P < 0.05). Heterozygous genotype individuals showed significantly higher HGF expression(P < 0.05), which was significantly greater in the 'CTCCAGGGTT' combined genotype than that in the'CCCCGGGGTT' combined genotype(P < 0.05). In addition, two alternative splicing variations, HGF-W and HGF-M,were identified, which resulted from alternative 3′ splice sites of exon 5, and HGF-W showed higher m RNA levels than HGF-M in all tissues.Conclusion: In summary, genetic variations within the HGF gene affected m RNA expression. These findings provide new insight into the molecular characteristics and functions of bovine HGF. | Hanfang Cai Yang Zhou Wenchao Jia Bowen Zhang Xianyong Lan Chuzhao Lei Xintang Fang Hong Chen | 2016 | Journal of Animal Science and Biotechnology2016，7，2： | 1 |

| 8 | Stretchable Parylene-C electrodes enabled by serpentine structures on arbitrary elastomers by silicone rubber adhesive显示文摘The delicate serpentine structures are widely used in high-performance stretchable electronics over the past decade.The metal interconnects encapsulated in biocompatible polymer Parylene-C film is a superior choice for long-term implantation in vivo,especially as neural interface to acquire electrophysiological signals or apply electrical stimulation.To avoid the physical contact damages from the neural tissues such as the brain or peripheral nerves,serpentine interconnects are utilized as stretchable electrodes and usually bonded to the soft elastomer substrate.The adhesion strength between the serpentine interconnects and the elastomer substrate becomes a considerable issue to ensure reliability and structural integrity.In this paper,the stretchable Parylene-C electrodes can be transfer printed onto arbitrary elastomer substrates by a thin layer of silicone rubber adhesive with low modulus for electrocorticogram(ECoG)recording.Mechanical simulation of serpentine structures consisting of same periodic arcs and different straight segments is investigated by uniaxial stretching.Then,the elastic stretchability of serpentine electrodes is further studied by simulation and experiments.After 5000 repetitive stretching cycles,the electrochemical impedance of microelectrodes remains in steady states.These results prove that the silicone rubber adhesive facilitates the interfacial bonding in the structure of stretchable electrodes as the compliant and reliable neural interface. | Bowen Ji Zhaoqian Xie Wen Hong Chunpeng Jiang Zhejun Guo Longchun Wang Xiaolin Wang Bin Yang Jingquan Liu | 2020 | Journal of Materiomics2020，6，2： | 1 |
| 9 | Study on business models of distributed generation in China显示文摘Along with the implementation of electricity sales-side reform and incremental power distribution investment liberalization under China’s new round of electricity market reform, the main subjects of distributed generation investment, construction, and operations have become more various, and the approaches as well as the ways that distributed generation takes part in the market have been more flexible. How to operate distributed generation economically and efficiently in this market environment has become an urgent issue to be addressed. Based on the domestic development situation of China’s distributed generation, this paper introduces typical existing business models of distributed generation, and elaborates the correlation between electricity market reform and business models of distributed generation in depth in combination with the contents of electricity market reform. At last, several business models of distributed generation which are feasible to be implemented in China have been proposed under the new electricity market reform based on successful international distributed generation operation experiences in the terms of stimulating stakeholders’ participation in the investment and operations of distributed generation. Characteristics of these recommended models are compared and analyzed as well. | Hui Yu Bowen Hong Wenpeng Luan Bibin Huang Yordanos Kassa Semero Abinet Tesfaye Eseye | 2018 | Global Energy Interconnection2018，1，2： | 1 |
| 10 | Tunable light emission from carbon dots by controlling surface defects显示文摘Carbon dots(CDs)are metal-free fluorescent materials that can be used in optical and electronic devices,but few studies have focused on one-step synthesis routes for CDs with tunable color and high photoluminescence quantum yield(PLQY).Herein,CDs with tunable light emission were synthesized using a novel amide-assisted solvothermal approach.The as-prepared CDs were well dispersed and homogeneous,with average diameters of approximately 2.0–4.0 nm,depending on the dopants.Owing to the surface states with different ratios of nitrogen-and oxygen-related species,different CDs can exhibit blue,green,red,or white emission with relatively high PLQYs of 61.6%,41.3%,29.1%and 19.7%,respectively.XPS measurements,in conjunction with DFT calculations,indicate that nitrogen substitution(pyridinic/pyrrolic nitrogen)dominates the blue emission,while introducing oxygen functional groups lowered the LUMO energy level,which resulted in redder emission.In addition,the CDs are demonstrated as a bioimaging probe in both in vitro and in vivo assays,and the white light CDs have been demonstrated to be potential fluorescent materials for white-light-emitting diode(WLED). | Huijun Li Sancan Han Bowen Lyu Ting Hong Shibo Zhi Ling Xu Fengfeng Xue Liman Sai Junhe Yang Xianying Wang Bin He | 2021 | Chinese Chemical Letters2021，32，9： | 1 |
| 11 | Long noncoding RNA(lncRNA)H19:An essential developmental regulator with expanding roles in cancer,stem cell differentiation,and metabolic diseases显示文摘Recent advances in deep sequencing technologies have revealed that,while less than 2%of the human genome is transcribed into mRNA for protein synthesis,over 80%of the genome is transcribed,leading to the production of large amounts of noncoding RNAs(ncRNAs).It has been shown that ncRNAs,especially long non-coding RNAs(lncRNAs),may play crucial regulatory roles in gene expression.As one of the first isolated and reported lncRNAs,H19 has gained much attention due to its essential roles in regulating many physiological and/or pathological processes including embryogenesis,development,tumorigenesis,osteogen-esis,and metabolism.Mechanistically,H19 mediates diverse regulatory functions by serving as competing endogenous RNAs(CeRNAs),Igf2/H19 imprinted tandem gene,modular scaffold,cooperating with H19 antisense,and acting directly with other mRNAs or lncRNAs.Here,we summarized the current understanding of H19 in embryogenesis and development,cancer development and progression,mesenchymal stem cell lineage-specific differentiation,and metabolic diseases.We discussed the potential regulatory mechanisms underlying H19’s func-tions in those processes although more in-depth studies are warranted to delineate the exact molecular,cellular,epigenetic,and genomic regulatory mechanisms underlying the physiolog-ical and pathological roles of H19.Ultimately,these lines of investigation may lead to the development of novel therapeutics for human diseases by exploiting H19 functions. | Junyi Liao Bowen Chen Zhenglin Zhu Chengcheng Du Shengqiang Gao Guozhi Zhao Piao Zhao Yonghui Wang Annie Wang Zander Schwartz Lily Song Jeffrey Hong William Wagstaff Rex CHaydon Hue HLuu Jiaming Fan Russell RReid Tong-Chuan He Lewis Shi Ning Hu Wei Huang | 2023 | Genes & Diseases2023，10，4： | 1 |
| 12 | Fully Printed High‑Performance n‑Type Metal Oxide Thin‑Film Transistors Utilizing Coffee‑Ring Effect显示文摘Metal oxide thin-films transistors(TFTs)produced from solution-based printing techniques can lead to large-area electronics with low cost.However,the performance of current printed devices is inferior to those from vacuum-based methods due to poor film uniformity induced by the“coffeering”effect.Here,we report a novel approach to print highperformance indium tin oxide(ITO)-based TFTs and logic inverters by taking advantage of such notorious effect.ITO has high electrical conductivity and is generally used as an electrode material.However,by reducing the film thickness down to nanometers scale,the carrier concentration of ITO can be effectively reduced to enable new applications as active channels in transistors.The ultrathin(~10-nm-thick)ITO film in the center of the coffee-ring worked as semiconducting channels,while the thick ITO ridges(>18-nm-thick)served as the contact electrodes.The fully inkjet-printed ITO TFTs exhibited a high saturation mobility of 34.9 cm2 V^(−1) s^(−1) and a low subthreshold swing of 105 mV dec^(−1).In addition,the devices exhibited excellent electrical stability under positive bias illumination stress(PBIS,ΔV_(th)=0.31 V)and negative bias illuminaiton stress(NBIS,ΔV_(th)=−0.29 V)after 10,000 s voltage bias tests.More remarkably,fully printed n-type metal–oxide–semiconductor(NMOS)inverter based on ITO TFTs exhibited an extremely high gain of 181 at a low-supply voltage of 3 V,promising for advanced electronics applications. | Kun Liang Dingwei Li Huihui Ren Momo Zhao Hong Wang Mengfan Ding Guangwei Xu Xiaolong Zhao Shibing Long Siyuan Zhu Pei Sheng Wenbin Li Xiao Lin Bowen Zhu | 2021 | Nano-Micro Letters2021，13，11： | 1 |
| 13 | Knockdown of insulin-like growth factor 2 gene disrupts mitochondrial functions in the liver显示文摘Even though insulin-like growth factor 2(IGF2)has been reported to be overexpressed in nonalcoholic fatty liver disease(NAFLD),its role in the progression of NAFLD and the potential mechanism remain largely unclear.Using in vitro models,we found that IGF2 was the key overexpressed gene in steatosis,suggesting a possible association between IGF2 and NAFLD.Interestingly,loss-of-function experiments revealed that inhibition of IGF2 protein impaired mitochondrial biogenesis and respiration.It additionally disrupted the expression changes of mitochondrial fusion and fission-related proteins necessary in maintaining mitochondrial homeostasis.Consistently,IGF2 knockdown reduced the mitochondrial membrane potential and increased the production of reactive oxygen species.Mechanistically,IGF2 regulates mitochondrial functions by modulating the expression of SIRT1 and its downstream gene PGCla.This research opens a new frontier on the role of IGF2 in energy metabolism,which potentially participates in the development of NAFLD.As such,IGF2 is a potential therapeutic target against NAFLD. | Weiwei Gui Yiyi Zhu Shuiya Sun Weifen Zhu Bowen Tan Hanxin Zhao Chengxin Shang Fenping Zheng Xihua Lin Hong Li | 2021 | Journal of Molecular Cell Biology2021，13，8： | 1 |
| 14 | 高山嵩草植物群落花期物候对增水的响应比对恒定增温和逐步增温的响应更敏感显示文摘有研究表明长期观测的植物花期物候变化温度敏感性与野外控制恒定增温试验所得出的花期物候温度敏感性结果不一致,这可能是由于两种观测方法具有不同的增温模式引起的。因为长期观测的气候变暖实际上是气温逐渐升高的情景,而野外控制增温试验所增加的温度是突然增加且每年保持不变。不同的增温模式是否会导致不同的结果目前还缺乏野外试验证据。此外,不同增温模式的效应还受到降水变化的调控。因此,我们于2015–2018年在高寒高山嵩草草甸开展了一项恒定增温(和对照相比,每年保持恒定增温1°C)和逐步增温(和对照相比,2015年增温0.25°C,以后逐年在前一年基础上再增温0.25°C,到2018年相比对照增温1°C)以及与增水(100%/50%)耦合的野外控制试验。研究结果发现,增温模式并没有显著改变群落花期物候。然而,增水显著提前了早花植物和中花植物的初花期,提前了早花植物的末花期,推迟了中花植物的末花期。增水处理并没有显著改变早花植物的开花持续期,但却显著延长了中花植物的开花持续期,进而延长了该群落的开花持续期。增温速率和增水处理并没有显著的交互作用。前一年的干旱会显著抑制第二年该植物群落的现存最大开花数。因此,无论增温模式如何,降水的改变对该高山嵩草植物群落花期物候的影响要大于增温对其的影响。 | Bowen Li Jianping Sun Shiping Wang Wangwang Lv Yang Zhou Peipei Liu Qi Wang Wang A Suren Zhang Lu Xia Huan Hong Lili Jiang Caiyun Luo Zhenhua Zhang Shilong Piao Yanfen Wang Tsechoe Dorji | 2023 | Journal of Plant Ecology2023，16，2： | 0 |
| 15 | Pharmacodynamic advantages and characteristics of traditional Chinese medicine in prevention and treatment of ischemic stroke显示文摘Ischemic stroke(IS) is a severe cerebrovascular disease with a high incidence, mortality, and disability rate. The first-line treatment for IS is the use of recombinant tissue plasminogen activator(r-t PA).Regrettably, numerous patients encounter delays in treatment due to the narrow therapeutic window and the associated risk of hemorrhage. Traditional Chinese medicine(TCM) has exhibited distinct advantages in preventing and treating IS. TCM enhances cerebral microcirculation, alleviates neurological disorders, regulates energy metabolism, mitigates infammation, reduces oxidative stress injuries, and inhibits apoptosis, thereby mitigating brain damage and preventing IS recurrence. This article summarizes the etiology, pathogenesis, therapeutic strategies, and relationship with modern biology of IS from the perspective of TCM, describes the advantages of TCM in the treatment of IS, and further reviews the pharmacodynamic characteristics and advantages of TCM in the acute and recovery phases of IS as well as in post-stroke complications. Additionally, it offers valuable insights and references for the clinical application of TCM in IS prevention and treatment, as well as for the development of novel drugs. | Hanyu Zhang Bowen Jin Xinyu You Pengrong Yi Hong Guo Lin Niu Qingsheng Yin Jiangwei Shi Yanjun Zhang Pengwei Zhuang | 2023 | Chinese Herbal Medicines2023，15，4： | 0 |
| 16 | Limbal epithelial stem cells in corneal surface reconstruction显示文摘Cornea serves as the partial front barrier and major light reflection organ of the eye.The integrity of corneal surface is essential for ocular function.Injuries or congenital diseases could significantly destruct the homeostasis of the ocular surface,especially the microenvironment of limbal epithelial stem cells(LESCs),and will eventually cause dysfunction of corneal regeneration and diminish of LESCs.The loss of LESCs by different reasons are named limbal stem cell deficiency(LSCD),which is one of the leading cause of vision loss worldwide.To restore the corneal surface,LESC transplantation in the form of tissue or cell cultures is currently a viable and promising method to treat LSCD.In this review,we aim to introduce the characters and niche of LESCs,and discuss different aspects of its application in cornea surface reconstruction. | Li Wang Bowen Wang Hong Ouyang | 2018 | Annals of Eye Science2018，，1： | 0 |
| 17 | Advances in the study of mitophagy in osteoarthritis显示文摘Osteoarthritis(OA),characterized by cartilage degeneration,synovial inflammation,and subchondral bone remodeling,is among the most common musculoskeletal disorders globally in people over 60 years of age.The initiation and progression of OA involves the abnormal metabolism of chondrocytes as an important pathogenic process.Cartilage degeneration features mitochondrial dysfunction as one of the important causative factors of abnormal chondrocyte metabolism.Therefore,maintaining mitochondrial homeostasis is an important strategy to mitigate OA.Mitophagy is a vital process for autophagosomes to target,engulf,and remove damaged and dysfunctional mitochondria,thereby maintaining mitochondrial homeostasis.Cumulative studies have revealed a strong association between mitophagy and OA,suggesting that the regulation of mitophagy may be a novel therapeutic direction for OA.By reviewing the literature on mitophagy and OA published in recent years,this paper elaborates the potential mechanism of mitophagy regulating OA,thus providing a theoretical basis for studies related to mitophagy to develop new treatment options for OA. | Hong CAO Xuchang ZHOU Bowen XU Han HU Jianming GUO Miao WANG Nan LI Jun ZOU | 2024 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2024，25，3： | 0 |
| 18 | Advances in the study of protein folding and endoplasmic reticulum-associated degradation in mammal cells显示文摘The endoplasmic reticulum is a key site for protein production and quality control.More than one-third of proteins are synthesized and folded into the correct three-dimensional conformation in the endoplasmic reticulum.However,during protein folding,unfolded and/or misfolded proteins are prone to occur,which may lead to endoplasmic reticulum stress.Organisms can monitor the quality of the proteins produced by endoplasmic reticulum quality control(ERQC)and endoplasmic reticulum-associated degradation(ERAD),which maintain endoplasmic reticulum protein homeostasis by degrading abnormally folded proteins.The underlying mechanisms of protein folding and ERAD in mammals have not yet been fully explored.Therefore,this paper reviews the process and function of protein folding and ERAD in mammalian cells,in order to help clinicians better understand the mechanism of ERAD and to provide a scientific reference for the treatment of diseases caused by abnormal ERAD. | Hong CAO Xuchang ZHOU Bowen XU Han HU Jianming GUO Yuwei MA Miao WANG Nan LI Jun ZOU | 2024 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2024，25，3： | 0 |
| 19 | Ultra-high temperature tolerant flexible transparent electrode with embedded silver nanowires bundle micromesh for electrical heater显示文摘To realize high performance flexible transparent electronics with extreme environmental adaptivity,Ag nanowires(Ag NWs)electrodes should simultaneously meet the requirements of high-temperature tolerance,chemical and mechanical robustness.Herein,a scalable Ag NWs bundle micro-meshes embedded in polyimide(Ag BMs/ePI)conducting film via a facile spray coating and transfer method is reported.Due to the synergistic effect of bundle micromesh and embedded architecture,the Ag BMs/ePI electrode exhibits high thermal stability(370℃ and 400℃ under ambient and nitrogen atmosphere conditions,respectively),low sheet resistance variation(<4%),good corrosion and deformation resistance.As an electrical heater,the Ag BMs/ePI can achieve~204℃ with the fast thermal response time of~8 s at 8 V,and exhibits good heating stability under bent condition.This work offers a promising platform for the emerging flexible transparent electronics to adapt extreme environments,especially for those devices which require high-temperature processing. | Bowen Sun Ruixue Xu Xu Han Jing Xu Wang Hong Yimeng Xu Zhiwei Fu He Zhu Xin Sun Jiangxin Wang Peng Cui Jingjing Chang Jiaqing Xiong Kai Qian | 2022 | npj Flexible Electronics2022，6，1： | 0 |
| 20 | Confocal photoluminescence characterization of silicon-vacancy color centers in 4H-SiC fabricated by a femtosecond laser显示文摘Silicon-vacancy(VSi)centers in silicon carbide(SiC)are expected to serve as solid qubits,which can be used in quantum computing and sensing.As a new controllable color center fabrication method,femtosecond(fs)laserwriting has been gradually applied in the preparation of VSi in SiC.In this study,4H-SiCwas directlywritten by an fs laser and characterized at 293 K by atomic force microscopy,confocal photoluminescence(PL),and Raman spectroscopy.PL signals of VSi were found and analyzed using 785 nm laser excitation by means of depth profiling and two-dimensional mapping.The influence of machining parameters on the VSi formation was analyzed,and the three-dimensional distribution of VSi defects in the fs laser writing of 4H-SiC was established. | Jiayu Liu Zongwei Xu Ying Song Hong Wang Bing Dong Shaobei Li Jia Ren Qiang Li Mathias Rommel Xinhua Gu Bowen Liu Minglie Hu Fengzhou Fang | 2020 | Nanotechnology and Precision Engineering2020，3，4： | 0 |
