| 1 | Super Na^(+)Half/Full Batteries and Ultrafast Na+Diffusion Kinetics of Cobalt-Nickel Selenide from Assembling Co_(0.5)Ni_(0.5)Se_(2)@NC Nanosheets into Cross-Stacked Architecture显示文摘Explorati on of adva need an ode materials for sodium-i on batteries(SIBs)is still a big challe nge due to the large radius of sodium.In this work,the hierarchical architectures assembled from N-doped carbon-coated Co_(0.5)Ni_(0.5)Se_(2)(Co_(0.5)Ni_(0.5)Se_(2)@NC)nanoparticles encapsulated into cross-stacked nano sheets have been successfully prepared from the cobalt-nickel bin ary-metal organic frameworks(CoNi-MOF)by two steps of the solid-state sele nizati on and carb on coating processes.Imports ntly,the resulta nt hierarchical Co0.5Nio:5Se2@NC architecture can achieve a satisfactory electrochemical performance,maintaining a high-rate capacity of 330 mA-h-g^(-1)1 at 3 A·g^(-1) and a stable cyclability of 100 cycles without obvious capacity decay at 0.2 A·g^(-1).The design of distinct superstructure can not only be applied to other electrode materials but also boost the forward development of energy storage systems. | Zhiyong Li Zilin Peng Rui Sun Zhaoxia Qin Xinlong Liu Caihong Wang Haosen Fan Shengjun Lu | 2021 | Chinese Journal of Chemistry2021，39，9： | 3 |
| 2 | Hypocoagulation induced by broadspectrum antibiotics in extensive burn patients显示文摘Background:Patients with extensive burns usually develop pro-coagulation soon after the injury if there is no sepsis occurred.We describe the case of an extensive burn adult suffering from hypocoagulation not related to sepsis,but secondary to antibiotic treatment.Case presentation:Here,we report a case of an adult male patient suffering from flame burns of 45%total body surface area(40%full thickness)combined with inhalation injury.Hypocoagulopathy with soaring prolonged activated partial thromboplastin time value occurred on third week post-burn while systemic infection had been under control by application of broad-spectrum antibiotics.Investigations showed that not the infection but vitamin K-related coagulation factor deficiency were responsible for unexpected bleeding.However,supplemental vitamin K was not the key as we expected,which prompted us trying to decode the underlying cause of coagulation disturbance in this patient and pick out the most effective treatment for live-saving.After the withdrawal of highly suspected broad-spectrum antibiotic,Meropenem^(■),disturbed vitamin K related coagulation factors gradually restored to their optimal levels so as to maintain normal coagulation status.Therefore,surgical procedures without further risk of bleeding could be carried out in time for wound recovery.The patient was discharged on post-burn day 67 and transferred to a secondary hospital for his rehabilitation.Conclusion:Hypocoagulopathy may be devoted to different reasons other than sepsis in extensive burns.Early recognition of the cause for coagulation disturbance is critical to make appropriate treatment and save patients’lives.This case illustrated the importance of unveiling the mist cause for coagulation disturbance occurred in extensive burn patient,which paved the way for optimal life-saving treatments.And we also recommend burn surgeons to be alerted to antibiotic-induced vitamin K deficiency-related coagulopathy among critical burn patients. | Jian Liu Yiqing Liu Shengjun Liu Qin Zhang Jiexin Zheng Yiwen Niu Xuefeng Wang | 2019 | Burns & Trauma2019，7，1： | 2 |
| 3 | N, O-doped carbon foam as metal-free electrocatalyst for efficient hydrogen production from seawater显示文摘Seawater electrolysis is the most promising technology for large scale hydrogen production due to the abundance and low cost of seawater in nature.However,compared with the traditional freshwater electrolysis,the issues of electrode poisoning and corrosion will occur during the seawater electrolysis process,and active and stable electrocatalysts for the hydrogen evolution reaction(HER)are thus highly desired.In this work,N,O-doped carbon foam in-situ derived from commercial melamine foam is proposed as a high-active metal-free HER electrocatalyst for seawater splitting.In acidic seawater,our catalyst shows high hydrogen generation performance with small overpotential of 161 mV at 10 mA·cm^(−2),a low Tafel slop of 97.5 mV·dec^(−1),and outstanding stability. | Qian Liu Shengjun Sun Longcheng Zhang Yongsong Luo Qin Yang Kai Dong Xiaodong Fang Dongdong Zheng Abdulmohsen Ali Alshehri Xuping Sun | 2022 | Nano Research2022，15，10： | 2 |

| 5 | Technical modifications & management innovations in exporting nuclear reactor projects显示文摘As a main channel for the foreign economic cooperation of China nuclear industry,China Zhongyuan Engineering Corporation (CZEC) has been constantly engaged in technical modifications and management innovations in its exporting nuclear reactor projects.In the implementation of heavy water research reactor contract in Algeria,CZEC had established a complete and adequate design standards system in compliance with the international standards,and made significant modifications to the reference reactor in the aspects of reactor power and reactor safety,solved quite some technical issues which affected the reactor technical performance.The modifications and improvements enabled the technical parameters,safety features,reactor multipurpose application to attain to the advanced level in the world.In the 300 MWe PWR NPPs in Pakistan,safety features had been updated in line with upgrading regulatory requisites.The design philosophy and technology application demonstrated CZEC's creation and innovation on basis of constant safety enhancement of nuclear power projects.Efforts had also been made by CZEC in promoting China made equipment items and components exportation. | Mao Xiaoming Qin xijiu Ding Hu Xue Zhaoqun Wen Shengjun | 2009 | Engineering Sciences2009，7，4： | 1 |
| 6 | Electrochemical and Pseudocapacitive Analysis of Rod-Like MoO_(2)@MoSe_(2)@NC Heterostructures for High-Performance Lithium Ion Batteries显示文摘A micro-scale rod-like heterostructure derived from molybdenum-based metal organic framework(Mo-MOF)has been successfully prepared via subsequent annealing treatment,which assembled from N-doped carbon encapsulated MoSe_(2) nanosheets grown on the surface of MoO_(2) microrod(named as MoO_(2)@MoSe_(2)@NC).For this novel heterostructure,the MoO_(2) nanoparticles assembled into rod core not only serve as supporting substrate for facilitating the fast kinetics of Li+cations inside the electrode but also protect the MoSe_(2) structure from restacking in the charge/discharge process.Moreover,the outer-layered MoSe2 nanosheets enable the fast lithium ion movement owing to its large interlayer spacing.Moreover,this unique rod-like core-shell structure composite could further effectively alleviate the structural strains caused by large volume expansion during charge/discharge process,thus leading to stable electrochemical performance when evaluated as anode material for lithium ion batteries.Electrochemical testing exhibits that the MoO_(2)@MoSe_(2)@NC heterostructure presents highly reversible capacity of 468 mAh g^(-1)at 0.5 A g^(-1)and superior rate capability(318 mAh g^(-1)even at 5.0 A g^(-1)),which is attributed to the synergistic effect of N-doped carbon encapsulated MoSe2 nanosheets and MoO_(2) nanoparticles. | Zhaoxia Qin Xinlong Liu Zhiyin Huang Rui Sun Zhiyong Li Haosen Fan Shengjun Lu | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，3： | 1 |
