| 1 | Electrochemical extraction of cerium and formation of Al–Ce alloy from CeO_2 assisted by AlCl_3 in LiCl–KCl melts显示文摘This work presents an electrochemical extraction of cerium and synthesization of Al–Ce alloy in LiCl–KCl melts on Mo and Al electrodes by chlorination of CeO2 using AlCl3 at 873 K. The cyclic voltammogram on Mo electrodes in LiCl–KCl–CeO2 melt showed no obvious reduction wave other than the reduction of Li(I). After the addition of AlCl3, the signals of the reaction of Ce(ⅡI)/Ce(0) and the synthesization of Al–Ce and Al–Li alloys were investigated by cyclic voltammetry, square-wave voltammetry, open-circuit chronopotentiometry and chronopotentiometry. These results indicated that AlCl3 can chloridize CeO2 and that it is possible to extract cerium and form Al–Ce and Al–Li–Ce alloys in LiCl–KCl–CeO2–AlCl3 melts. According to potentiostatic electrolysis, only the Al4 Ce layer coated the Al electrodes. According to galvanostatic electrolysis, Al–Ce(Al4Ce, Al3 Ce, and Al92Ce8), Al2Li3, and Al phases were formed on Mo electrodes, and the content of cerium in the Al–Li–Ce alloys was more than 17 wt%. | ZHANG Meng WANG HaoYu HAN Wei ZHANG MiLin LI YunNa WANG YanLi XUE Yun MA FuQiu ZHANG XingMei | 2014 | Science China Chemistry2014，57，11： | 2 |

| 3 | Efficient bright γ-ray vortex emission from a laser-illuminated light-fan-in-channel target显示文摘X/γ-rays have many potential applications in laboratory astrophysics and particle physics.Although several methods have been proposed for generating electron,positron,and X/γ-photon beams with angular momentum(AM),the generation of ultra-intense brilliant γ-rays is still challenging.Here,we present an all-optical scheme to generate a high-energy γ-photon beam with large beam angular momentum(BAM),small divergence,and high brilliance.In the first stage,a circularly polarized laser pulse with intensity of 10^(22) W/cm^(2) irradiates a micro-channel target,drags out electrons from the channel wall,and accelerates them to high energies via the longitudinal electric fields.During the process,the laser transfers its spin angular momentum(SAM)to the electrons’orbital angular momentum(OAM).In the second stage,the drive pulse is reflected by the attached fan-foil and a vortex laser pulse is thus formed.In the third stage,the energetic electrons collide head-on with the reflected vortex pulse and transfer their AM to the γ-photons via nonlinear Compton scattering.Three-dimensional particle-in-cell simulations show that the peak brilliance of the γ-ray beam is∼10^(22) photons·s^(-1)·mm^(-2)·mrad^(-2) per 0.1% bandwidth at 1 MeV with a peak instantaneous power of 25 TW and averaged BAM of 10^(6)h/photon.The AM conversion efficiency from laser to the γ-photons is unprecedentedly 0.67%. | Hao Zhang Jie Zhao Yanting Hu Qianni Li Yu Lu Yue Cao Debin Zou Zhengming Sheng Francesco Pegoraro Paul McKenna Fuqiu Shao Tongpu Yu | 2021 | High Power Laser Science and Engineering2021，9，3： | 1 |
| 4 | Laser chirp controlled relativistic few-cycle mid-infrared pulse generation显示文摘Relativistic few-cycle mid-infrared(mid-IR)pulses are unique tools for strong-field physics and ultrafast science,but are difficult to generate with traditional nonlinear optical methods.Here,we propose a scheme to generate such pulses with high efficiency via plasma-based frequency modulation with a negatively chirped laser pulse(NCLP).The NCLP is rapidly compressed longitudinally due to dispersion and plasma etching,and its central frequency is downshifted via photon deceleration due to the enhanced laser intensity and plasma density modulations.Simulation results show that few-cycle mid-IR pulses with the maximum center wavelength of 7.9µm and pulse intensity of a_(MIR)=2.9 can be generated under a proper chirp parameter.Further,the maximum energy conversion efficiency can approach 5.0%.Such a relativistic mid-IR source is promising for a wide range of applications. | Dongao Li Guobo Zhang Jie Zhao Yanting Hu Yu Lu Hao Zhang Qianni Li Dongze Zhang Rong Sha Fuqiu Shao Zhengming Sheng Tongpu Yu | 2023 | High Power Laser Science and Engineering2023，11，5： | 0 |
| 5 | Electroextraction of neodymium from LiCl-KCl melt using binary liquid Ga-Al cathode显示文摘The electrochemical behaviour of Nd(Ⅲ)ion was investigated on inert W,active Ga and Ga-AI cathodes.It is established that the reduction of Nd(Ⅲ)ion on the inert electrode is a consecutive two-step process while that on the active electrodes is a one-step process.The apparent standard potential of the Nd(Ⅲ)/Nd redox couple at different temperatures was determined by open-circuit chronopotentiometry and semi-differential method,and the relationship between temperature and apparent standard potential was further discussed.The thermodynamic properties of Nd in Ga and Ga-Al electrodes such as activity coefficient and activity were evaluated via intermittent coulomb titration and temperature dependence test,and the effect of temperature on activity coefficient was verified.Finally,Nd was successfully extracted in form of alloy from molten salt by galvanostatic electrolysis,in which the current efficiency of91.7%for the electroextraction indicates that the binary liquid Ga-Al electrode has favorable performance. | Li Ding Xuepeng Wang Yongde Yan Valeri Smolenski Wenda Xu Alena Novoselova Yun Xue Fuqiu Ma Xingmei Zhang | 2023 | Journal of Rare Earths2023，41，8： | 0 |
