| 1 | Flaking and degradation of polyurethane coatings after 2 years of outdoor exposure in Lhasa显示文摘The exposure of a high gloss polyurethane aircraft topcoat system with polyurethane intermediate coating and epoxy primer to strong ultraviolet radiation in Lhasa,Tibet was studied by using scanning electron microscopy(SEM) ,atomic force microscopy(AFM) ,attenuated total reflectance Fourier-transform infrared(ATR-FTIR) ,and X-ray photoelectron spectroscopy(XPS) .Micro-flakes were found to form on the topcoat surface after exposure and the size and quantity of the flakes increased with the increase of the exposure time.The magnitude of micro-bulges and the topcoat roughness increased after a long exposure to sunlight. Flakes and micro-bulges resulted in the loss of the topcoat gloss.ATR-FTIR and XPS analysis indicated that chain scissions of the polyurea C==O group and the polyurethane C―O―C and CO―NH groups occurred,and the degradation products of NH and carbonyl groups formed due to the exposure.The breaking of the chemical structure of the polyurethane resulted in a decrease in its elasticity and in the adhesion of the flakes to its surface. | LIU FuChun HAO YongSheng WANG ZhenYu SHI HongWei HAN EnHou KE Wei | 2010 | Chinese Science Bulletin2010，55，7： | 7 |
| 2 | A 357.9 nm GaN/AlGaN multiple quantum well ultraviolet laser diode显示文摘Ultraviolet(UV)and deep-UV light emitters are prom-ising for various applications including bioagent detection,wa-ter and air purification,dermatology,high-density optical stor-age,and lithography.However,to achieve shorter UV laser di-odes(LDs),especially for the LDs with lasing wavelength less than 360 nm,requires high AlN mole fraction AlGaN clad-ding layer(CL)and waveguide(WG)layers,which usually leads to generate cracks in AlGaN epilayer due to lack of lat-tice-matched substrates.Meanwhile,due to high resistivity of high AlN mole fraction Mg doped AlGaN layers,only few groups have reported GaN-based LDs with emission wavelength shorter than 360 nm[1−8],and up to now,there is no room temperature continuous-wave(CW)operation UV LDs with a lasing wavelength shorter than 360 nm ever repor-ted.Previously,we have reported a UV LD with lasing wavelength of 366 nm[9].In this paper,a higher AlN mole frac-tion of AlGaN WG layers is employed to shorten the LD emis-sion wavelength to less than 360 nm.A lasing wavelength of 357.9 nm is achieved. | Jing Yang Degang Zhao Zongshun Liu Feng Liang Ping Chen Lihong Duan Hai Wang Yongsheng Shi | 2022 | Journal of Semiconductors2022，43，1： | 6 |

| 8 | Roll-to-roll imprint for high precision grating manufacturing显示文摘In this paper,a novel roll-to-roll imprint process is proposed to fabricate gratings in large area. The key challenges in roll-to-roll imprint process,such as the roller mold preparation,imprint system,misalignment of imprint roller and backup roller,and also the imprint pressure,are investigated. Various gratings with different periods and profiles are obtained by the roll-to-roll process. To calibrate the measuring ability of the self-made grating by imprint,a calibration system is built with a dual-frequency laser interferometer. By the calibration,the self-made gratings can achieve ±4μm accuracy in 45mm measuring distance. | Liu Hongzhong Shi Yongsheng Yin Lei Jiang Weitao Lu Bingheng | 2013 | Engineering Sciences2013，11，1： | 3 |
| 9 | Proteomics provides individualized options of precision medicine for patients with gastric cancer显示文摘While precision medicine driven by genome sequencing has revolutionized cancer care,such as lung cancer,its impact on gastric cancer(GC)has been minimal.GC patients are routinely treated with chemotherapy,but only a fraction of them receive the clinical benefit.There is an urgent need to develop biomarkers or algorithms to select chemo-sensitive patients or apply targeted therapy.Here,we carried out retrospective analyses of 1,020 formalin-fixed,paraffin-embedded GC surgical resection samples from 5 hospitals and developed a mass spectrometry-based workflow for proteomic subtyping of GC.We identified two proteomic subtypes:the chemo-sensitive group(CSG)and the chemo-insensitive group(CIG)in the discovery set.The 5-year overall survival of CSG was significantly improved in patients who had received adjuvant chemotherapy after surgery compared with those who received surgery only(64.2%vs.49.6%;Cox P-value=0.002),whereas no such improvement was observed in CIG(50.0%vs.58.6%;Cox P-value=0.495).We validated these results in an independent validation set.Further,differential proteome analysis uncovered 9 FDA-approved drugs that may be applicable for targeted therapy of GC.A prospective study is warranted to test these findings for future GC patient care. | Wenwen Huang Dongdong Zhan Yazhuo Li Nairen Zheng Xin Wei Bin Bai Kecheng Zhang Mingwei Liu Xuefei Zhao Xiaotian Ni Xia Xia Jinwen Shi Cheng Zhang Zhihao Lu Jiafu Ji Juan Wang Shiqi Wang Gang Ji Jipeng Li Yongzhan Nie Wenquan Liang Xiaosong Wu Jianxin Cui Yongsheng Meng Feilin Cao Tieliu Shi Weimin Zhu Yi Wang Lin Chen Qingchuan Zhao Hongwei Wang Lin Shen Jun Qin | 2021 | Science China(Life Sciences)2021，64，8： | 3 |
| 10 | Evolution of the Xiaotian-Mozitan fault and its implications for exhumation of Dabie HP-UHP rocks显示文摘The Xiaotian-Mozitan fault(XMF)located north of the Dabie orogenic belt separates the North Dabie complex to the south from the Beihuaiyang low-grade metamorphic rocks to the north.It comprises several NW-striking ductile shear zones and brittle faults.The brit-tle faults obviously overprinted on the ductile shear zones and promoted the development of the volcanic basins in early Cretaceous to the north,which suggests that the brittle faults were normal faults formed in early Cretaceous during doming of the Dabie orogenic belt.The ductile shear zone superposed on the north Dabie gray gneiss,and it is an important channel where the Dabie HP-UHP rocks exhumed.For obtaining new structural constraint on exhumation of the HP-UHP rocks,we present here experimental results on the microstructure,quartz C-axis fabrics and the microprobe analyses of phengite.The ductile shear zone was determined to be formed at a temperature of 600-650°C and pressure of 1.1 GPa by the mineral deformation,microprobe analyses and geobarometry of Si-in-phengite of the mylonite,the results suggest that the mylonite now exposed on the surface experienced an upper amphibolite-facies metamorphism in the lower crust.The mineral stretching lineation varies from horizontal in the east segment to sub-dip in the west.Shear sense indicators from outcrop and thin sections of orientated specimen and quartz C-axis fabrics suggest that the XMF is a sinis-tral normal fault.The kinematics analysis of the ductile shear zone indicates that the exhumation of Dabie HP-UHP rocks is the results of a SE-directed extrusion and an anticlockwise rotation around its eastern pivot simultaneously. | Biwei Xiang Yongsheng Wang Changcheng Li Guang Zhu Yonghong Shi | 2008 | Progress in Natural Science:Materials International2008，18，6： | 3 |

| 13 | Effect of operating parameters on the performance of thermally regenerative ammonia-based battery for low-temperature waste heat recovery显示文摘This study investigated the important factors that affect the operating parameters of thermally regenerative ammoniabased batteries(TRABs),including the metal electrode type,membrane type,electrode surface area,electrode distance,electrolyte concentration,and ammonia concentration.The experimental results showed that the maximum power density of TRABs with a Cu electrode was 40.0 W·m^(2),which was considerably higher than that with Ni(0.34 W·m^(2))and Co(0.14 W·m^(2))electrodes.TRABs with an anion exchange membrane had a 28.6%higher maximum power density than those with a cation exchange membrane.An increased electrode surface resulted in an increased maximum power but a decreased maximum power density.Within a certain range,TRAB performance was enhanced with decreased electrode distance and increased electrolyte concentration.An increased ammonia concentration resulted in enhanced ammonia transfer and improved the TRAB performance. | Yu Shi Liang Zhang Jun Li Qian Fu Xun Zhu Qiang Liao Yongsheng Zhang | 2021 | Chinese Journal of Chemical Engineering2021，34，4： | 2 |

| 18 | Myeloid-derived suppressor cells as immunosuppressive regulators and therapeutic targets in cancer显示文摘Myeloid-derived suppressor cells(MDSCs)are a heterogenic population of immature myeloid cells with immunosuppressive effects,which undergo massive expansion during tumor progression.These cells not only support immune escape directly but also promote tumor invasion via various non-immunological activities.Besides,this group of cells are proved to impair the efficiency of current antitumor strategies such as chemotherapy,radiotherapy,and immunotherapy.Therefore,MDSCs are considered as potential therapeutic targets for cancer therapy.Treatment strategies targeting MDSCs have shown promising outcomes in both preclinical studies and clinical trials when administrated alone,or in combination with other anticancer therapies.In this review,we shed new light on recent advances in the biological characteristics and immunosuppressive functions of MDSCs.We also hope to propose an overview of current MDSCs-targeting therapies so as to provide new ideas for cancer treatment. | Kai Li Houhui Shi Benxia Zhang Xuejin Ou Qizhi Ma Yue Chen Pei Shu Dan Li Yongsheng Wang | 2021 | Signal Transduction and Targeted Therapy2021，6，11： | 2 |
| 19 | Preparation of superhydrophobic silver nano coatings with feather-like structures by electroless galvanic deposition显示文摘Superhydrophobic silver nanocoatings with feather-like morphology are fabricated on copper substrates by electroless galvanic deposition. The coating exhibit superhydrophobicity with a contact angle of 156.4° and glide angle of 4° without any further surface modification. Scanning electron microscope (SEM), X-ray diffraction (XRD) and contact angle measurements are used to investigate the morphology, crystal structure and superhydrophobicity, respectively, of the coatings. The coatings exhibit high thermal stability; their water contact angle did not change when the coatings were heated to 200°C for 2 h. The mechanism of superhydrophobicity of the silver coating is discussed based on the work of Amirfazli, Wenzel and Cassie. | FENG XiaoJuan SHI YanLong WANG YongSheng YUE GuoRen YANG Wu | 2013 | Chinese Science Bulletin2013，58，16： | 2 |
| 20 | Phase-field simulation of early-stage kinetics evolution ofγ’phase in medium supersaturation Co-Al-W alloy显示文摘The early precipitation ofγ’-Co3(Al,W)phase affects the spatial distribution and kinetic evolution of precipitates for the morphology transmission effect,but the nucleation and concomitant growth are not studied still by aging experiments due to the expeditious precipitation ofγ’phase in Co-Al-W alloy.By using the phase-field simulation with sublattice free energy,the early-stage kinetics evolution ofγ’-Co3(Al,W)phase in a medium supersaturation Co-9 Al-8 W(at.%)alloy aged from 1023 K to 1173 K is investigated.The influences of aging temperature on the evolution of morphology and composition ofγ’phase,and the kinetics of nucleation and growth to coarsening are clarified.It is found that the rates of composition evolution of W inγphase are two or three times that ofγ’phase,and the W compositions inγandγ’phases show a linear relationship with time t–1/3,which means that the coarsening takes place earlier at high temperature.In addition,the equilibrium partitioning ratios indicate Al and W partition into theγ’phase and the ratios decrease with elevated temperature.The compositional variations across theγ/γ’phase interfaces suggest that low aging temperature makes the stoichiometric ratio closer to 3:1.Moreover,the precipitation evolutions from early nucleation to growth and coarsening in Co-Al-W alloy are distinguished,and the rate constants of square and cube of average particles radius increase with temperature.In later growth stage,the relationship of the square of average particles radius and time is obeyed,while the steady-state coarsening stage follows the cube law.The time exponents of particles number density at the coarsening stage are close to–1 of Kuehmann-Voorhees(KV)theory.The study demonstrates that the early-stage evolution ofγ’phase which is undiscovered in the experiment can be captured by the phase-field simulation,and the resultant kinetics laws agree well with the experimental and theoretical results. | Shujing Shi Zhengwei Yan Yongsheng Li Suleman Muhammad Dong Wang Shi Chen Shengshunjin | 2020 | Journal of Materials Science & Technology2020，52，18： | 2 |
