| 1 | From concept to reality-A review to the primary test stand and its preliminary application in high energy density physics显示文摘Pulsed power technology,whereas the electrical energy stored in a relative long period is released in much shorter timescale,is an efficient method to create high energy density physics(HEDP)conditions in laboratory.Around the beginning of this century,China Academy of Engineering Physics(CAEP)began to build some experimental facilities for HEDP investigations,among which the Primary Test Stand(PTS),a multi-module pulsed power facility with a nominal current of 10 MA and a current rising time~90 ns,is an important achievement on the roadmap of the electro-magnetically driven inertial confinement fusion(ICF)researches.PTS is the first pulsed power facility beyond 10 TW in China.Therefore,all the technologies have to be demonstrated,and all the engineering issues have to be overcome.In this article,the research outline,key technologies and the preliminary HEDP experiments are reviewed.Prospects on HEDP research on PTS and pulsed power development for the next step are also discussed. | Jianjun Deng Weiping Xie Shuping Feng Meng Wang Hongtao Li Shengyi Song Minghe Xia Ji Ce An He Qing Tian Yuanchao Gu Yongchao Guan Bin Wei Xianbin Huang Xiaodong Ren Jiakun Dan Jing Li Shaotong Zhou Hongchun Cai Siqun Zhang Kunlun Wang Qiang Xu Yujuan Wang Zhaohui Zhang Guilin Wang Shuai Guo Yi He Yiwei Zhou Zhanji Zhang Libing Yang Wenkang Zou | 2016 | Matter and Radiation at Extremes2016，1，1： | 19 |
| 2 | Three-year results of small incision lenticule extraction and wavefront-guided femtosecond laser-assisted laser in situ keratomileusis for correction of high myopia and myopic astigmatism显示文摘AIM: To compare and calculate the 3-year refractive results, higher-order aberrations(HOAs), contrast sensitivity(CS) and dry eye parameters after small incision lenticule extraction(SMILE) and wavefront-guided femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK) for correction of high myopia and myopic astigmatism.METHODS: In this prospective, non-randomized comparative study, 78 eyes with spherical equivalent(SE) of-8.11±1.09 diopters(D) received a SMILE surgery, and 65 eyes with SE of-8.05±1.12 D received a wavefront-guided FS-LASIK surgery with the Visu Max femtosecond laser(Carl Zeiss Meditec, Jena, Germany) for flap cutting. Visual acuity, manifest refraction, CS, HOAs, ocular surface disease index(OSDI) and tear break-up time(TBUT) were evaluated during a 3-year follow-up.RESULTS: The difference of uncorrected distance visual acuity(UDVA) postoperatively was achieved at 1 mo and at3 mo, whereas the difference of the mean UDVA between two groups at 3 y were not statistically significant(t=-1.59,P=0.13). The postoperative change of SE was 0.89 D in the FS-LASIK group(t=5.76, P=0.00), and 0.14 D in the SMILE group(t=0.54, P=0.59) from 1 mo to 3 y after surgery.At 3-year postoperatively, both HOAs and spherical aberrations in the SMILE group were obviously less than those in the FS-LASIK group(P=0.00), but the coma root mean square(RMS) was higher in the SMILE group(0.59±0.26) than in the FS-LASIK group(0.29±0.14, P=0.00).The mesopic CS values between two groups were not statistically significant at 3 y postoperatively. Comparedwith the FS-LASIK group, lower OSDI scores and longer TBUT values were found in the SMILE group at 1 mo and 3 mo postoperatively. With regard to safety, no eye lost any line of CDVA in both groups at 3 y after surgery. CONCLUSION: Both SMILE and wavefront-guided FSLASIK procedures provide good visual outcomes. Both procedures are effective and safe, but SMILE surgery achieve more stable long-term refractive outcome and better control of early postoperative dry eye as compared to FS-LASIK. | Li-Kun Xia Jing Ma He-Nan Liu Ce Shi Qing Huang | 2018 | International Journal of Ophthalmology(English edition)2018，11，3： | 16 |

| 4 | Potential of multi-pass ECAP on improving the mechanical properties of a high-calcium-content Mg-Al-Ca-Mn alloy显示文摘In this study,the multi-pass equal channel angular pressing(ECAP)was employed on a high-calcium-content Mg-Al-Ca-Mn alloy to tailor its microstructure and mechanical properties.The obtained results showed that the network-shaped Mg2Ca and(Mg,Al)2Ca eutectic compounds in as-cast alloy were gradually crushed into ultra-fine particles after ECAP,which exhibited a bimodal particle size distribution and most aggregated at original grain boundaries.Dynamic recrystallization(DRX)of α-Mg occurred during hot deformation via a particle stimulated mechanism,and the almost complete DRX with an average grain size around 1.5μm was obtained after 12p-ECAP.Moreover,abundant nano-sized acicular and spherical precipitates were dynamically precipitated withinα-Mg grains during ECAP.Tensile test results indicated that the maximum strength and ductility were acquired for 12p-ECAP alloy with ultimate tensile strength of 372 MPa and fracture elongation of 8%.The enhanced strength of the alloy could be ascribed to fine DRX grains,ultra-fine Ca-containing particles and dynamically precipitated nano-precipitates,while the improved ductility was mainly due to the refined and homogeneous microstructure,and weak texture with high average Schmid factors. | He Huang Huan Liu Ce Wang Jiapeng Sun Jing Bai Feng Xue Jinghua Jiang Aibin Ma | 2019 | Journal of Magnesium and Alloys2019，7，4： | 10 |

| 7 | Microstructure and Mechanical Properties of Mg–RE–TM Cast Alloys Containing Long Period Stacking Ordered Phases: A Review显示文摘Casting magnesium alloys hold the greatest share of magnesium application products due to their short processing period, low cost and near net shape forming. Compared with conventional commercial magnesium alloys or other Mg–RE-based alloys, the novel Mg–RE–TM cast alloys with long period stacking ordered(LPSO) phases usually possess a higher strength and are promising candidates for aluminum alloy applications. Up to now, two ways: alloying design and casting process control(including subsequent heat treatments), have been predominantly employed to further improve the mechanical properties of these alloys. Alloying with other elements or ceramic particles could alter the solidifi cation pattern of alloys, change the morphology of LPSO phases and refi ne the microstructures. Diff erent casting techniques(conventional casting, rapidly solidifi cation, directional solidifi cation, etc.) introduce various microstructure characteristics, such as dendritic structure, nanocrystalline, metastable phase, anisotropy. Further heat treatments could activate the transformation of various LPSO structures and precipitation of diverse precipitates. All these evolutions exert great impacts on the mechanical properties of the LPSO-containing alloys. However, the underlying mechanisms still remain a subject of debate. Therefore, this review mainly provides the state of the art of the casting magnesium alloys research and the accompanying challenges and summarizes some topics that merit future investigation for developing high-performance Mg–RE–TM cast alloys. | Huan Liu He Huang Jia-Peng Sun Ce Wang Jing Bai Ai-Bin Ma Xian-Hua Chen | 2019 | Acta Metallurgica Sinica(English Letters)2019，32，3： | 6 |
| 8 | Decoration of Electrospun Nanofibers with Magnetic Nanoparticles via Electrospinning and Sol-gel Process显示文摘Polyacrylonitrile(PAN)/Fe 3 O 4 composite nanofibers were successfully obtained through electrospinning and sol-gel technology. The resulting magnetic Fe 3 O 4 nanoparticles were homogeneously distributed on the surface of PAN nanofibers and the diameters of polyacrylonitrile nanofibers and nanoparticles were easily controlled, respectively. The distribution of Fe 3 O 4 nanoparticles inside the nanofibrous composite was investigated by field emission scanning electron microscopy and transmission electron microscopy. X-ray diffraction reveals the presence of Fe 3 O 4 nanoparticles in the composite nanofiber. The resulting sample shows a super paramagnetic behavior. | YANG Fan ZHENG Wei HUANG Hui-min LI Zhen-yu ZHANG Hong-nan WANG Wei WANG Ce | 2010 | Chemical Research in Chinese Universities2010，26，5： | 3 |
| 9 | The safety and efficacy of modified minimally invasive trabeculectomy for the treatment of primary chronic angle-closure glaucoma显示文摘Background: Primary chronic angle-closure glaucoma(PCACG) is one of the main types of glaucoma in China. Trabeculectomy is the most commonly used glaucoma filtration surgery for glaucoma in the world. Conventional trabeculectomy is prone to anesthesia-related complications intraoperative and operationrelated complications postoperative in PCACG treatment. Modified minimally invasive trabeculectomy maybe can reduce the incidence of complications.Methods: We conducted a prospective case series study and performed modified fornix-based trabeculectomy in 27 patients(30 eyes) under topical anesthesia; we then observed intraoperative anesthesia and cooperation ef ect, intraoperative and postoperative complications, preoperative and postoperative visual acuity, intraocular pressure(IOP), visual field, and the use of ocular hypotensive drugs. The patients were followed up for at least 12 months.Results: All operations were completed successfully with no intraoperative complications. All 27 patients(30 eyes) were followed up for at least 12 months. No significant decrease in visual acuity was observed at days 1 or 7 and at months 1, 3, 6, and 12 after operation; however, a signii cant decrease in IOP was observed at days 1 and 7 and at months 1, 3, 6, and 12 after operation. Moreover, no significant progression in visual field mean defect was observed at month 12 after operation, and the number of ocular hypotensive drugs required was significantly reduced at months 6 and 12 after operation. By month 12 after operation, the overall success rate was 93.33%(28/30).Conclusions: Modii ed minimally invasive trabeculectomy is safe and ef ective for the treatment of PCACG. | Zhenggen Wu Chukai Huang Ce Zheng Yuqiang Huang Wanqi Zhang Di Ma | 2015 | Eye Science2015，30，4： | 3 |

| 11 | Pharmacokinetics and tissue distribution of intraperitoneal 5-fluorouracil with a novel carrier solution in rats显示文摘AIM: To compare the pharmacokinetics and tissue distribution of 5-fluorouracil administered intraperitoneally with two isotonic carrier solutions: HAES-steri (neotype 6% hydroxyethyl starch), a novel carrier solution with middle molecular weight and physiologic saline (0.9% sodium chloride solution), a traditional carrier solution for intraperitoneal chemotherapy, in rats. METHODS: A total of 60 Sprague Dawley rats were randomized into groups according to the carrier solution administered. Each group was further randomized according to the intraperitoneal dwell period (1, 3, 6, 12, 18 and 24 h). At the end of the procedure the rats were killed, the peritoneal fluid was withdrawn completely and quantitated. Drug concentrations in peritoneal fluid, plasma, and tissues were determined by high- performance liquid chromatography. RESULTS: The mean volumes remaining in the peritoneal cavity were significantly higher with HAES- steri than those with physiologic saline at 1, 6, 12, 18, and 24 h (P = 0.047, 0.009, 0.005, 0.005 and 0.005 respectively, the percentages of remaining peritoneal fluid volume were 89.9 ± 5.6 vs 83.4 ± 4.9, 79.9 ± 2.8 vs 56.2 ± 15.7, 46.8 ± 5.5 vs 24.7 ± 9.7, 23.0 ± 2.8 vs 0.0 ± 0.0 and 4.2 ± 1.7 vs 0.0 ± 0.0 respectively). Mean concentrations in peritoneal fluid were significantly higher with HAES-steri than those with physiologic saline at 3, 12 and 18 h (P = 0.009, 0.009 and 0.005 respectively, the concentrations were 139.2768 ± 28.2317 mg/L vs mg/L, 11.5427 ± 3.0976 mg/L vs 0.0000 ± 0.0000 mg/L and 4.7724 ± 1.0936 mg/L vs 0.0000 ± 0.0000 mg/L respectively). Mean plasma 5-fluorouracil concentrations in portal vein were significantly higher with HAES-steri at 3, 12, 18 and 24 h (P = 0.009, 0.034, 0.005 and 0.019 respectively, the concentrations were 3.3572 ± 0.8128 mg/L vs 0.8794 ± 0.2394 mg/L, 0.6203 ± 0.9935 mg/L vs 0.0112 ± 0.0250 mg/L, 0.3725 ± 0.3871 mg/L vs 0.0000 ± 0.0000 mg/L, and 0.2469 ± 0.1457 mg/L vs 0.0000 ± 0.0000 mg/L respectively), but significantly lower at 1 h (P = 0.009, the concentrations were 4.1957 ± 0.6952 mg/L vs 7.7406 ± 1.2377 mg/L). There were no significant differences in the plasma 5-fluorouracil in inferior caval vein at each time-point. 5-fluorouracil concentrations were significantly greater with HAES-steri at 18 h in gastric tissue (P = 0.016, the concentrations were 0.9486 ± 0.8173 mg/L vs 030392 ± 0.0316 mg/L), at 18 h in colon (P = 0.009, the concentrations were 0.1730 ± 0.0446 mg/L vs 0.0626 ± 0.0425 mg/L), at 3, 6, 12 and 24 h in liver (P = 0.009, 0.013, 0.034 and 0.013 respectively, the concentrations were 0.6472685 ± 0.5256 mg/L vs 0.1554 ± 0.1043mg/L, 0.8606826 ± 0.7155 mg/L vs 0.0014 ± 0.0029 mg/L, 0.0445 ± 0.0330 mg/L vs 0.0797 ± 0.1005 mg/L and 0.0863 ± 0.0399 mg/L vs 0.0034 ± 0.0075 mg/L respectively) and at 18 h in lung (P = 0.009, the concentrations were 0.0886 ± 0.0668 mg/L vs 0.0094 ± 0.0210 mg/L). There were no differences in 5-fluorouracil concentrations in renal tissue at each time-point. CONCLUSION: The use of intraperitoneal 5-fluoro- uracil with HAES-Steri carrier solution provides a pharmacokinetic advantage for a local-regional killing of residual tumor cells and improve the accumulated penetrability of 5-fluorouracil with decreased systemic toxicity. Further clinical feasibility studies on the use of HAES-steri as carrier solution for intraperitoneal chemotherapy with 5-fluorouracil are warranted. | Zhi-Gang Wei Guo-Xin Li Xiang-Cheng Huang Li Zhen Jiang Yu Hai-Jun Deng Shan-Hua Qing Ce Zhang | 2008 | World Journal of Gastroenterology2008，14，14： | 2 |

| 13 | Edge superconductivity in multilayer WTe2 Josephson junction显示文摘WTe2,as a type-ⅡWeyl semimetal,has 2D Fermi arcs on the(O01)surface in the bulk and 1D helical edge states in its monolayer.These features have recently attracted wide attention in condensed matter physics.However,in the intermediate regime between the bulk and monolayer,the edge states have not been resolved owing to its closed band gap which makes the bulk states dominant.Here,we report the signatures of the edge superconductivity by superconducting quantum interference measurements in multilayerWTe2 Josephson junctions and we directly map the localized supercurrent.In thickWTe(~60nm),the supercurrent is uniformly distributed by bulk states with symmetricJosephson effect(|Ic+(B)|=|Ic^-(B)|).In thin WTe2(10 nm),however,the supercurrent becomes confined to the edge and its width reaches up to 1.4μm and exhibits non-symmetric behavior|Ic^+(B)|≠|Ic^-(B)|.The ability to tune the edge domination by changing thickness and the edge superconductivity establishes WTez as a promising topological system with exotic quantum phases and a rich physics. | Ce Huang Awadhesh Narayan Enze Zhang Xiaoyi Xie Linfeng Ai Shanshan Liu Changjiang Yi Youguo Shi Stefano Sanvito Faxian Xiu | 2020 | National Science Review2020，7，9： | 2 |
| 14 | Zebrafish hhex-null mutant develops an intrahepatic intestinal tube due to de-repression of cdx1b and pdx1显示文摘The hepatopancreatic duct (HPD) system links the liver and pancreas to the intestinal tube and is composed of the extrahepatic biliary duct, gallbladder, and pancreatic duct. Haematopoietically expressed-homeobox (Hhex) protein plays an essential role in the establishment of HPD;however, the molecular mechanism remains elusive. Here, we show that zebrafish hhex-null mutants fail to develop the HPD system characterized by lacking the biliary marker Annexin A4 and the HPD marker sox9b. The hepatobiliary duct part of the mutant HPD system is replaced by an intrahepatic intestinal tube characterized by expressing the intestinal marker fatty acid-binding protein 2a (fabp2a). Cell lineage analysis showed that this intrahepatic intestinal tube is not originated from hepatocytes or cholangiocytes. Further analysis revealed that cdx1b and pdx1 are expressed ectopically in the intrahepatic intestinal tube and knockdown of cdx1b and pdx1 could restore the expression of sox9b in the mutant. Chromatin-immunoprecipitation analysis showed that Hhex binds to the promoters of pdx1 and cdx1b genes to repress their expression. We therefore propose that Hhex, Cdx1b, Pdx1, and Sox9b form a genetic network governing the patterning and morphogenesis of the HPD and digestive tract systems in zebrafish. | Ce Gao Weidong Huang Yuqi Gao Li Jan Lo Lingfei Luo Honghui Huang Jun Chen Jinrong Peng | 2019 | Journal of Molecular Cell Biology2019，11，6： | 2 |
| 15 | A Novel Strategy of In Situ Trimerization of Cyano Groups Between the Ti3C2Tx(MXene) Interlayers for High-Energy and High-Power Sodium-Ion Capacitors显示文摘2D MXenes are attractive for energy storage applications because of their high electronic conductivity.However,it is still highly challenging for improving the sluggish sodium(Na)-ion transport kinetics within the MXenes interlayers.Herein,a novel nitrogen-doped Ti3C2Tx MXene was synthesized by introducing the in situ polymeric sodium dicyanamide(Na-dca)to tune the complex terminations and then utilized as intercalation-type pseudocapacitive anode of Na-ion capacitors(NICs).The Na-dca can intercalate into the interlayers of Ti3C2 Tx nanosheets and simultaneously form sodium tricyanomelaminate(Na3TCM)by the catalyst-free trimerization.The as-prepared Ti3C2Tx/Na3TCM exhibits a high N-doping of 5.6 at.%in the form of strong Ti-N bonding and stabilized triazine ring structure.Consequently,coupling Ti3C2Tx/Na3 TCM anode with different mass of activated carbon cathodes,the asymmetric MXene//carbon NICs are assembled.It is able to deliver high energy density(97.6 Wh kg-1),high power output(16.5 kW kg-1),and excellent cycling stability(≈82.6%capacitance retention after 8000 cycles). | Siyang Liu Fangyuan Hu Wenlong Shao Wenshu Zhang Tianpeng Zhang Ce Song Man Yao Hao Huang Xigao Jian | 2020 | Nano-Micro Letters2020，12，10： | 2 |
| 16 | High-quality genome assembly of Huazhan and Tianfeng,the parents of an elite rice hybrid Tian-you-hua-zhan显示文摘High-quality rice reference genomes have accelerated the comprehensive identification of genome-wide variations and research on functional genomics and breeding.Tian-you-hua-zhan has been a leading hybrid in China over the past decade.Here,de novo genome assembly strategy optimization for the rice indica lines Huazhan(HZ)and Tianfeng(TF),including sequencing platforms,assembly pipelines and sequence depth,was carried out.The PacBio and Nanopore platforms for long-read se-quencing were utilized,with the Canu,wtdbg2,SMARTdenovo,Flye,Canu-wtdbg2,Canu-SMARTdenovo and Canu-Flye assemblers.The combination of PacBio and Canu was optimal,considering the contig N50 length,contig number,assembled genome size and polishing process.The assembled contigs were scaffolded with Hi-C data,resulting in two“golden quality”rice reference genomes,and evaluated using the scaffold N50,BUSCO,and LTR assembly index.Furthermore,42,625 and 41,815 non-transposable element genes were annotated for HZ and TF,respectively.Based on our assembly of HZ and TF,as well as Zhenshan97,Minghui63,Shuhui498 and 9311,comprehensive variations were identified using Nipponbare as a reference.The de novo assembly strategy for rice we optimized and the“golden quality”rice genomes we produced for HZ and TF will benefit rice genomics and breeding research,especially with respect to uncovering the genomic basis of the elite traits of HZ and TF. | Hui Zhang Yuexing Wang Ce Deng Sheng Zhao Peng Zhang Jie Feng Wei Huang Shujing Kang Qian Qian Guosheng Xiong Yuxiao Chang | 2022 | Science China(Life Sciences)2022，65，2： | 2 |

| 19 | InSe/hBN/graphite heterostructure for high-performance 2D electronics and flexible electronics显示文摘Two-dimensional(2D)materials as channel materials provide a promising alternative route for future electronics and flexible electronics,but the device performance is affected by the quality of interface between the 2D-material channel and the gate dielectric.Here we demonstrate an indium selenide(lnSe)/hexagonal boron nitride(hBN)/graphite heterostructure as a 2D field-effect transistor(FET),with InSe as channel material,hBN as dielectric,and graphite as gate.The fabricated FETs feature high electron mobility up to 1,146 cm2·V^-1·s^-1 at room temperature and on/off ratio up to 1010 due to the atomically flat gate dielectric.Integrated digital inverters based on InSe/hBN/graphite heterostructures are constructed by local gating modulation and an ultrahigh voltage gain up to 93.4 is obtained.Taking advantages of the mechanical flexibility of these materials,we integrated the heterostructured InSe FET on a flexible substrate,exhibiting little modification of device performance at a high strain level of up to 2%.Such high-performance heterostructured device configuration based on 2D materials provides a new way for future electronics and flexible electronics. | Liangmei Wu Jinan Shi Zhang Zhou Jiahao Yan Aiwei Wang Ce Bian Jiajun Ma Ruisong Ma Hongtao Liu Jiancui Chen Yuan Huang Wu Zhou Lihong Bao Min Ouyang Sokrates T.Pantelides Hong-Jun Gao | 2020 | Nano Research2020，13，4： | 1 |
| 20 | Scattering of seismic waves by three-dimensional large-scale hill topography simulated by a fast parallel IBEM显示文摘To solve seismic wave scattering by a large-scale three-dimensional(3-D) hill topography, a fast parallel indirect boundary element method(IBEM) is developed by proposing a new construction method for the wave field, modifying the generalized minimum residual(GMRES) algorithm and constructing an Open MP plus MPI parallel model. The validations of accuracy and efficiency show that this method can solve 3-D seismic response of a large-scale hill topography for broadband waves, and overcome the weakness of large storage and low efficiency of the traditional IBEM. Based on this new algorithm architecture, taking the broadband scattering of plane SV waves by a large-scale Gaussian-shaped hill of thousands-meters height as an example, the influence of several important parameters is investigated, including the incident frequency, the incident angle and the height-width and length-width ratio of the hill. The numerical results illustrate that the amplification effect on the ground motion by a near-hemispherical hill is more significant than the narrow hill. For low-frequency waves, the scattering effect of the higher hill is more pronounced, and there is only a single peak near the top of the hill. However, for high-frequency waves, rapid spatial variation of displacement amplitude appears on the hill surface. | Liu Zhongxian Shang Ce Huang Lei Liang Jianwen Li Jie | 2020 | Earthquake Engineering and Engineering Vibration2020，19，4： | 1 |
