As a novel X-ray focusing technology, lobster eye micro-pore optics (MPO) feature both wide observing field of view and true imaging capability, promising sky monitoring with significantly improved sensitivity spatial resolution in soft X-rays. Since first proposed by Angel (1979), the have been extensively studied, developed trialed over past decades. In this Letter, we report on first-light results from flight experiment Lobster Eye Imager for Astronomy ($LEIA$), pathfinder wide-field...
Magnetic anisotropy of Co40Fe40B20 thin films sandwiched between Ta and MgO layers was investigated. properties CoFeB deposited on top bottom layer are different. The thickness the annealing temperature critical parameters to achieve keep perpendicular magnetic anisotropy. phase diagram anisotropic strength temperatures thicknesses is observed. According diagrams, CoFeB/MgO/CoFeB tunnel junctions were fabricated, tunneling magnetoresistance (TMR) ratio higher than 30% at low temperatures.
The Lobster Eye Imager for Astronomy (LEIA), a pathfinder of the Wide-field X-ray Telescope Einstein Probe (EP) mission, was successfully launched onboard SATech-01 satellite Chinese Academy Sciences on 27 July 2022. In this paper, we introduce design and on-ground test results LEIA instrument. Using state-of-the-art Micro-Pore Optics (MPO), wide field-of-view (FoV) 346 square degrees (18.6 * 18.6 degrees) imager is realized. An optical assembly composed 36 MPO chips used to focus incident...
"Sumali," as an imported cobalt ore from overseas, was a sort of precious and valuable pigment used for imperial kilns only, which produces characteristic "iron spot" to blue-and-white porcelain in early Ming Dynasty (A.D. 14th-15th century). Although there were some old studies on it, the morphology formation iron spot has not been fully investigated understood. Therefore, five selected samples with typical Jingdezhen kiln Yongle periods 1403-1424) analyzed by various microscopic analysis...
We have successfully manipulated the electronic properties of FeSe thin flakes based on a field-effect transistor with solid proton conductor as gate dielectric. The phase diagram function voltage demonstrates three evident discrete superconducting phases ${T}_{\mathrm{c}}$ corresponding to $\ensuremath{\sim}8, \ensuremath{\sim}34$, and $\ensuremath{\sim}42$ K, respectively, which is similar those observed in ${\mathrm{Li}}_{x}\mathrm{FeSe}$ ${\mathrm{Na}}_{x}\mathrm{FeSe}$ by tuning Li or...
The Xing kiln, which is located in Xingtai, Hebei Province, famous for white porcelain production, especially translucent porcelain. However, the translucency, as most important characteristic of porcelain, rarely mentioned. In this study, eight samples including and non‐translucent excavated from kiln are quantitatively analysed by a transmittance tester. study points out defects previous concept based on light proposes new definition translucency. Translucent not deliberately thinned fine...
Objective To investigate the recent effect and safety of magnetic resonance guided focused ultrasound (MRgFUS) for treating uterine fibroids with a Meta analysis. Methods Such databases as Cochrane Library,PubMed,EMbase, CBM,CNKI,CQVIP Wanfang were searched from their establishment. After thestudy selected, assessment data extraction conducted by two reviewers independently, Meta-analysis performed using Comprehensive V2 software. The volume non-perfusion ratio (NPVR), fibroid...
