| 1 | Mechanical properties of Mg-8Gd-3Y-0.5Zr alloy with bimodal grain size distributions显示文摘The Mg-Gd-Y-Zn-Zr alloys are representational and potential age-hardening systems as reported in the past ten years,but their mechanical properties are still dependent on the grain size and its distribution.The effect of bimodal structure on mechanical properties of Mg-8Gd-3Y-0.5Zr alloy with bimodal grain size distributions was investigated.The results suggested that the volume fraction of fine grain(FG)and coarse grain(CG)could be controlled by combined processes of hot forging,extrusion and annealing.And for the present alloys with bimodal grain size distribution,the improvement of strength is still attributed to the grain refinement.The morphology of bimodal grain size distribution has a marked impact on the ductility of the alloy,i.e.with the increase of coarse grain volume fraction,the elongation to failure increases at the beginning and then decreases.The mechanism of the toughening effect of bimodal grain size distribution on the Mg-Gd-Y-Zn-Zr alloys with bimodal grain size structure has been discussed. | J.H.He L.Jin F.H.Wang S.Dong J.Dong | 2017 | Journal of Magnesium and Alloys2017，5，4： | 15 |
| 2 | Midinfrared optical frequency comb based on difference frequency generation using high repetition rate Er-doped fiber laser with single wall carbon nanotube film显示文摘We demonstrated stable midinfrared(MIR) optical frequency comb at the 3.0 μm region with difference frequency generation pumped by a high power, Er-doped, ultrashort pulse fiber laser system. A soliton mode-locked161 MHz high repetition rate fiber laser using a single wall carbon nanotube was fabricated. The output pulse was amplified in an Er-doped single mode fiber amplifier, and a 1.1–2.2 μm wideband supercontinuum(SC) with an average power of 205 m W was generated in highly nonlinear fiber. The spectrogram of the generated SC was examined both experimentally and numerically. The generated SC was focused into a nonlinear crystal, and stable generation of MIR comb around the 3 μm wavelength region was realized. | M.Tsuzuki L.Jin M.Yamanaka V.Sonnenchein H.Tomita A.Sato T.Ohara Y.Sakakibara E.Omoda H.Kataura T.Iguchi N.Nishizawa | 2016 | Photonics Research2016，4，6： | 2 |

| 7 | Productivity of well-watered Panicum virgatum does not increase with CO_(2) enrichment显示文摘Aims Rising atmospheric CO_(2) has been shown to increase aboveground net primary productivity(ANPP)in water-limited perennial grasslands,in part by reducing stomatal conductance and transpiration,thereby reducing depletion of soil moisture.However,the benefits of CO_(2) enrichment for ANPP will vary with soil type and may be reduced if water limitation is low.Little is known about CO_(2) effects on ANPP of Panicum virgatum,a perennial C4 tallgrass and potential bioenergy crop.We hypothesized that if water limitation is minimized,(i)CO_(2) enrichment would not increase P.virgatum ANPP because photosynthetic rates of this C4 grass would not increase and because decreased transpiration at elevated CO_(2) would provide little additional benefit in increased soil moisture and(ii)soil type will have little effect on P.virgatum CO_(2) responses because of high overall soil moisture.Methods Growth and leaf physiology of P.virgatum cv.‘Alamo’were studied as plants established for 4 years on silty clay and clay soils along a 250 to 500 ll l-1 gradient in atmospheric CO_(2) located in central Texas,USA.Plants were watered to replace evapotranspiration,fertilized with NO_(3)NH_(4) and P_(2)O_(5) and clipped to standard height during mid-season.Important Findings ANPP increased through the third year of growth.Soil moisture(0–20 cm),ANPP,tiller numbers and leaf area index were 8–18%higher on the clay than on the silty clay soil.ANPP did not increase with CO_(2) except in the planting year.However,biomass removed with clipping strongly increased with CO_(2) in years 2 and 3,suggesting that CO_(2) enrichment increased the early-to mid-season growth of establishing P.virgatum but not later regrowth or that of fully established plants.Furthermore,CO_(2) enrichment differentially affected two components of ANPP in years 2 and 3,increasing tiller mass and reducing tiller numbers.This reallocation of resources in clipped P.virgatum suggested increased meristem limitation of productivity with CO_(2) enrichment.CO_(2) enrichment had little effect on photosynthesis but increasingly reduced stomatal conductance and transpiration as the plants established.As a result,water use efficiency became increasingly coupled to CO_(2) as leaf area increased during establishment.These results suggest that for well-watered and clipped P.virgatum,ANPP differed between soil types,was not affected by CO_(2) enrichment when fully established but interacted with clipping to alter allocation patterns during establishment.Soil type effects on ANPP-CO_(2) responses will likely become more apparent when water is more limiting. | Philip A.Fay H.Wayne Polley Virginia L.Jin Michael J.Aspinwall | 2012 | Journal of Plant Ecology2012，5，4： | 0 |
