Honeycomb cordierite coated with Cu-SSZ-13 zeolite is widely.used for the selective cataly.ic reduction of NO_(x) with NH_(3)(NH_(3)-SCR)to reduce pollutants from vehicle ***,conventional honeycomb cataly.ts fabricated via coating techniques are limited by low zeolite loadings,loss of the deposited zeolites,and complicated preparation ***,a facile,one-step three-dimensional(3D)printing strategy is developed to construct MnO_(x)/Cu-SSZ-13 monolithic cataly.ts with excellent cataly.ic performance for NH_(3)-***-containing halloysite nanotubes(Fe-HNTs)are introduced as printing ink additives to ensure mechanical stability and modulate the NH_(3)-SCR performance of monolithic cataly.ts in high temperature *** situ incorporation of Mn into the Cu-SSZ-13 zeolite monoliths during the 3D printing process boosts the mechanical strength of the monolithic structures from 2.54 MPa to 4.33 MPa as well as broadens the temperature window(165-550℃)of the cataly.ts for NH_(3)-SCR with NO_(x) conversion of above 80%.Such robust multicomponent-integrated 3D-printed selfsupporting cataly.ts not only.possess high zeolite loading and excellent cataly.ic activity,but also avoid complicated manufacturing processes,which contrasts with conventional honeycomb cataly.ts fabricated by extrusion coupled with coating.

Soybean is an important legume crop that displays the classic shade avoidance syndrome(SAS),including exaggerated stem elongation,which leads to lodging and yield reduction under density farming ***,we compared the effects of two shade signals,low red light to far-red light ratio(R:FR)and low blue light(LBL),on soybean status and revealed that LBL predominantly.induces excessive stem *** used CRISPR-Cas9-engineered Gmcry mutants to investigate the functions of seven cryptochromes(GmCRYs)in soybean and found that the four GmCRY1s overlap in mediating LBL-induced *** GmCRY1s increase the abundance of the bZlP transcription factors STF1 and STF2,which directly.upregulate the expression of genes encoding GA2 oxidases to deactivate GA1 and repress stem ***,GmCRY1b overexpression lines displayed multiple agronomic advantages over the wild-type control under both dense planting and intercropping *** study demonstrates the integration of GmCRY1-mediated signals with the GA metabolic pathway in the regulation of LBL-induced SAS in *** also provides a promising option for breeding lodging-resistant,high-yield soybean cultivars in the future.

Using the FengYun-3C(FY-3C)onboard BeiDou Navigation Satellite System(BDS)and Global Positioning System(GPS)data from 2013 to 2017,this study investigates the performance and contribution of BDS to precise orbit determination(POD)for a low-Earth orbit(LEO).The overlap comparison result indicates that code bias correction of BDS can improve the POD accuracy by 12.4%.The multi-year averaged one-dimensional(1D)root mean square(RMS)of the overlapping orbit differences(OODs)for the GPS-only.solution is 2.0,1.7,and 1.5 cm,respectively.during the 2013,2015,and 2017 *** 1D RMS for the BDS-only.solution is 150.9,115.0,and 47.4 cm,respectively.during the 2013,2015,and 2017 periods,which is much worse than the GPS-only.solution due to the regional system of BDS and the few BDS channels of the FY-3C *** the BDS and GPS combined solution(also known as the GC combined solution),the averaged 1D RMS is 2.5,2.3,and 1.6 cm,respectively.in 2013,2015,and 2017,while the GC combined POD presents a significant accuracy improvement after the exclusion of geostationary Earth orbit(GEO)*** main reason for the improvement seen after this exclusion is the unfavorable satellite tracking geometry and poor orbit accuracy of GEO *** accuracy of BDS-only.and GC combined solutions have gradually.improved from 2013 to 2017,thanks to improvements in the accuracy of International GNSS Service(IGS)orbit and clock products in recent years,especially.the availability of a high-frequency satellite clock product(30 s sampling interval)since ***,the GC POD(without GEO)was able to achieve slightly.better accuracy than the GPS-only.POD in 2017,indicating that the fusion of BDS and GPS observations can improve the accuracy of LEO *** combined POD can significantly.improve the reliability of LEO POD,simply.due to system *** increased contribution of BDS to LEO POD can be expected with the launch of more BDS satellites and with further improvements in

The Shanwang Basin is a small Cenozoic sedimentary basin located in Linqu county, Shandong *** Shanwang Formation, especially.the diatomaceous shale member, contains diverse and finely.preserved flora and fauna fossils （Fig. 1）. Previous paleontological study and radiometric dating show that it was formed in the Miocene. However, on the precise age of the formation, there are such different opinions as Late Miocene, Middle Miocene, Early.stage of Middle Miocene, etc.

目的为探究ZM6铸造镁合金表面斑点缺陷产生的原因及其形成机理。方法通过扫描电子显微镜(SEM)对未经机加工和经机加工后的ZM6铸造镁合金表面不同形态的斑点缺陷进行形貌分析,并结合能量色散X射线谱(EDS)对斑点缺陷的化学成分进行检测,最后耦合合金铸态组织和力学性能进行综合分析。结果未经机加工的ZM6铸造镁合金表面斑点缺陷呈深黑色,而经机加工后的ZM6铸造镁合金表面斑点缺陷呈白色,且部分白色斑点中心有一小块黑色区域。不过未经机加工和经机加工后的ZM6铸造镁合金表面斑点缺陷都呈现龟裂状、其与基体的过渡界面处均未发现任何空隙存在,且其主要成分均为Mg的氧化物或氢氧化物、同时含有Cl、K等由溶剂引入的杂质元素,但未经机加工的ZM6铸造镁合金表面斑点缺陷中Cl元素的含量相对较高,而经机加工后的ZM6铸造镁合金表面斑点缺陷中K元素的含量相对较高。值得指出的是,经机加工后的ZM6铸造镁合金表面白色斑点中黑色区域存在微小气孔。结论ZM6铸造镁合金表面斑点缺陷的产生是由Mg的化学腐蚀及电偶腐蚀造成的,而不是由氧化夹杂造成的。因此,通过加强ZM6铸造镁合金精炼效果以获得化学成分均匀的熔体是获得高质量构件的有效途径。
