| 1 | Experimental study of hydrogen-rich/oxygen-rich gas–gas injectors显示文摘Five types of coaxial injectors were investigated experimentally using hot hydrogen-rich gas and oxygen-rich gas,which were respectively provided by a GH2/GO2hydrogen-rich perburner and a GH2/GO2oxygen-rich preburner.The injectors were the shear coaxial injector,the oxidizer post expansion coaxial injector,the fuel impinging coaxial injector,the central body coaxial injector,and the shear tri-coaxial injector.The characteristic velocity effciency and the combustor's wall temperatures were obtained for different design parameters through the experiments.It can be concluded that angles of the oxidizer post expansion and the fuel impinging have little influence on the combustion performance and the wall temperatures.The contact area between fuel and oxidizer and the mass flow rate have signifcant impacts on the combustion performance.The shear tri-coaxial injector has the best combustion performance but also the highest wall temperatures among the fve types of injectors. | Jin Ping Li Mao Cai Guobiao | 2013 | Chinese Journal of Aeronautics2013，26，5： | 1 |
| 2 | Regulatory considerations for animal studies of biomaterial products显示文摘Animal studies play a vital role in validating the concept,feasibility,safety,performance and efficacy of biomaterials products during their bench-to-clinic translation.This article aims to share regulatory considerations for animal studies of biomaterial products.After briefly emphasizing the importance of animal studies,issues of animal studies during biomaterial products’translation are discussed.Animal studies with unclear purposes,flawed design and poor reporting quality could significantly reduce the translation efficiency and create regulatory challenges.Regulatory perspectives on the purpose,principle,quality and regulatory science of animal studies are also presented.Animal studies should have clear purposes,follow principles of 3R+DQ(replacement,reduction,refinement,design and quality)and execute under an efficiently operating quality management system.With the advancement of regulatory science,National Medical Products Administration of China has been developing a series of standards and guidance documents on animal studies of medical devices.Case studies of making decisions on whether to conduct animal studies are provided in the end with drug-eluting stents as examples.In summary,animal studies of biomaterial products should pay close attention to the rationale,design and quality in order to achieve their purposes. | Maobo Cheng Wenbo Liu Jiazhen Zhang Song Zhang Zhaojun Guo Lu Liu Jiaxin Tian Xiangmei Zhang Jin Cheng Yinghui Liu Gang Deng Guobiao Gao Lei Sun | 2022 | Bioactive Materials2022，7，5： | 1 |

| 4 | Numerical investigation on the drag characteristics of supercritical water flow past a sphere显示文摘Numerical simulation has become a useful approach to explore the complex physical and chemical process inside the supercritical water(SCW)fluidized bed reactor.Due to the drastic and non-linear variation of water properties near pseudocritical point,the flow field and drag coefficient of SCW flow past a cold particle are considerably different from that of conventional flow.Therefore,in this work,particle-resolved numerical investigation is conducted to study the flow field and drag characteristics under the influence of the special water properties variation.Through varying the enthalpy corresponding to the particle surface temperature,which will be called the particle surface enthalpy for short,in a wide range,it realizes the study under different properties variation tendencies.The simulated results demonstrate that the variations of drag coefficient versus Reynolds number(Re)and particle surface enthalpy are in good regularity when taking the freestream temperature as reference temperature.The drag coefficient is enhanced greatly at high enthalpy difference between particle surface and inflow,and the enhancement is mainly contributed by that of the frictional drag coefficient.Moreover,the drag coefficient variations under different pressures are in good agreement when cases are set with the same inflow and particle surface enthalpies,respectively.By fitting the simulated results,a new drag coefficient correlation is developed for Re range of 10–200 with consideration of the influence of the special properties variation.The fitting quality is good that the maximum deviation between the new correlation and simulated data is 13.92%,and the mean deviation is 3.67%. | WU ZhenQun OU GuoBiao REN YiFei JIN Hui | 2020 | Science China(Technological Sciences)2020，63，8： | 1 |

| 6 | Interfacial characteristics in CNTs-AgCuTi systems显示文摘AgCuTi-based composite fillers reinforced with Carbon Nanotubes(CNTs) were prepared by mechanical ball milling and ultrasonic agitation. The morphological features, chemical components, and melting characteristics of the composite fillers with different content of CNTs addition were investigated using Field Emission Scanning Electron Microscopy(FESEM), XRay Diffraction(XRD) and a Differential Scanning Calorimeter(DSC). After being heated at 900 ℃, the microstructure of the composite fillers was examined through FESEM and Transmission Electron Microscopy(TEM) to analyze the interfacial characteristics in the AgCuTi-CNTs system.The microstructures of the composite fillers with 0.5 wt% CNTs and 0.1 wt% CNTs were compared. It was found that 0.5 wt% CNTs were favorable for dispersive distribution of the structure.Nano-sized TiC particles formed in the reaction of CNTs with Ti, resulting in the transformation of TiCu;with high Ti content and Ti;Cu;phases to TiCu;phase with low Ti content. Additionally,the microstructure evolution of the composite fillers was studied by changing the ratio of Ti/CNTs.Results showed that CNTs significantly influenced the wettability of the AgCuTi filler. After addition of 0.3 wt% of CNTs, the spreading area of the composite filler on the C/C composite increased by 146.0%. | Duo LIU Bin CHEN Guobiao JIN Yanyu SONG Qi ZHANG Xiaoguo SONG Jian CAO | 2022 | Chinese Journal of Aeronautics2022，35，4： | 0 |
| 7 | Technological innovations on direct carbon mitigation by ordered energy conversion and full resource utilization显示文摘Coal consumption leads to over 15 billion tons of global CO_(2) emissions annually,which will continue at a considerable intensity in the foreseeable future.To remove the huge amount of CO_(2),a practically feasible way of direct carbon mitigation,instead of capturing that from dilute tail gases,should be developed;as intended,we developed two innovative supporting technologies,of which the status,strengths,applications,and perspective are discussed in this paper.One is supercritical water gasification-based coal/biomass utilization technology,which orderly converts chemical energy of coal and low-grade heat into hydrogen energy,and can achieve poly-generation of steam,heat,hydrogen,power,pure CO_(2),and minerals.The other one is the renewables-powered CO_(2) reduction techniques,which uses CO_(2) as the resource for carbon-based fuel production.When combining the above two technical loops,one can achieve a full resource utilization and zero CO_(2) emission,making it a practically feasible way for China and global countries to achieve carbon neutrality while creating substantial domestic benefits of economic growth,competitiveness,well-beings,and new industries. | Liejin Guo Zhisong Ou Ya Liu Zhiwei Ge Hui Jin Guobiao Ou Mengmeng Song Zihao Jiao Wenhao Jing | 2022 | Carbon Neutrality2022，1，1： | 0 |
