| 1 | Formation and evolution of layered structure in dissimilar welded joints between ferritic-martensitic steel and 316L stainless steel with fillers显示文摘Dissimilar high-energy beam(HEB)welding is necessary in many industrial applications.Different composition of heat-affected zone(HAZ)and weld metal(WM)lead to variation in mechanical properties within the dissimilar joint,which determines the performance of the welded structure.In the present study,appropriate filler material was used during electron beam welding(EBW)to obtain a reliable dissimilar joint between reduced-activation ferritic-martensitic(RAFM)steel and 316L austenitic stainless steel.It was observed that the layered structure occurred in the weld metal with 310S filler(310S-WM),which had the inferior resistance to thermal disturbance,leading to severe hardening of 310S-WM after one-step tempering treatment.To further ameliorate the joint inhomogeneity,two-step heat treatment processes were imposed to the joints and optimized.δ-ferrite in the layered structure transformed intoγ-phase in the first-step normalizing and remained stable during cooling.In the second-step of tempering,tempered martensite was obtained in the HAZ of the RAFM steel,while the microstructure of 310S-WM was not affected.Thus,the optimized properties for HAZ and 310S-WM in dissimilar welded joint was both obtained by a two-step heat treatment.The creep failure position of two dissimilar joints both occurred in CLAM-BM. | Guoliang Liu Shanwu Yang Jianwen Ding Wentuo Han Lujun Zhou Mengqi Zhang Shanshan Zhou RDKMisra Farong Wan Chengjia Shang | 2019 | Journal of Materials Science & Technology2019，35，11： | 4 |
| 2 | Highlights of the 2nd International Symposium on Tribbles and Diseases: tribbles tremble in therapeutics for immunity, metabolism, fundamental cell biology and cancer显示文摘The Tribbles(TRIB) family of pseudokinase proteins has been shown to play key roles in cell cycle, metabolic diseases, chronic inflammatory disease, and cancer development. A better understanding of the mechanisms of TRIB pseudokinases could provide new insights for disease development and help promote TRIB proteins as novel therapeutic targets for drug discovery. At the 2 nd International Symposium on Tribbles and Diseases held on May 7–9, 2018 in Beijing, China, a group of leading Tribbles scientists reported their findings and ongoing studies about the effects of the different TRIB proteins in the areas of immunity, metabolism, fundamental cell biology and cancer. Here, we summarize important and insightful overviews from 4 keynote lectures, 13 plenary lectures and 8 short talks that took place during this meeting. These findings may offer new insights for the understanding of the roles of TRIB pseudokinases in the development of various diseases. | Bing Cui Patrick A. Eyers Leonard L.

| 3 | Metal-organic framework-derived carbon nanotubes with multi-active Fe-N/Fe sites as a bifunctional electrocatalyst for zinc-air battery显示文摘Sustainable metal-air batteries demand high-efficiency,environmentally-friendly,and non-precious metal-based electrocatalysts with bifunctionality for both the oxygen reduction reaction(ORR)and oxygen evolution reaction(OER).In this research,novel functional carbon nanotubes with multi-active sites including well-dispersed single-atom iron throughout the walls and encapsulated ultrafine iron nanoparticles were synthesized as an electrocatalyst(FeNP@Fe-N-C)through one-step pyrolysis of metal-organic frameworks.High-resolution synchrotron powder X-ray diffraction and X-ray absorption spectroscopy were applied to characterize the unique structure of the electrocatalyst.In comparison to the commercial Pt/C and Ru O_(2)electrodes,the newly prepared FeNP@Fe-N-C presented a superb bifunctional performance with its narrow potential difference(Egap)of 0.73 V,which is ascribed to the metallic Fe nanoparticles that boosts the adsorption and activation of oxygen on the active sites with an enhanced O_(2)adsorption capacity of 7.88 cm^(3)g^(-1)and synergistically functionalizes the iron atoms dispersed on the nanotubes.A rechargeable zinc-air battery based on FeNP@Fe-N-C exhibited a superior open-circuit voltage(1.45 V),power density(106.5 m W cm^(-2)),and stable cycling performance.The green technique developed in this work for the fabrication of functional nanotubes raises the prospect of making more efficient electrocatalysts for sustainable energy cells. | Chao Yang Shanshan Shang Qinfen Gu Jin Shang Xiao-yan Li | 2022 | Journal of Energy Chemistry2022，31，3： | 1 |
| 4 | Woman Mayor Devotes Herself to Her People显示文摘SHI Lijun used to be the Deputy Secretary of the Municipal Party Committee of Zibo in Shandong Province. When she stood before the 257 deputies to the People’s Congress in Laiwu on January 12, 1993, she perceived the anticipation and skepticism in their eyes. Although the deputies voted her into office as the first woman mayor of this city because of her past achievement in her official career, they still wanted to know what she would | SHANG SHAOHUA CHEN SHANSHAN | 1995 | Women of China1995，，11： | 0 |
| 5 | Successful Marriage Requires Tolerance显示文摘1 THE question of whether or not the concept of marriage goes against human nature will never be resolved because there is nothing more contradictory in the world than so-called human nature. Everyone should ask a more specific question: What do I want most out of my life? If a person wants peaceful life, he or she should get married. If a person wants freedom, he or she should remain single. Can a person have both a peaceful life and freedom? There is such a thing called an open marriage. But marriage is on the threshold of freedom. In reality, perhaps it is easy or difficult to cross that threshold. But the threshold must be there. Without it, the marriage would be totally open, and the union could not be regarded as a marriage. It is essential that in marriage the idea that the | SHANG YAPING ZHOU GUOPING CHEN SHANSHAN | 1995 | Women of China1995，，6： | 0 |
