The new pulsar navigation method Significance Enhancement of Pulse-profile with Orbit-dynamics is adopted to determine the orbit with observations of only one pulsar. In this test, the Crab pulsar is chosen and observed by Insight-HXMT from 2017 August 31 to September 5. Using the five-day long observation data, the orbit of Insight-HXMT is determined successfully with the three telescopes onboard: High Energy X-ray Telescope, Medium Energy X-ray Telescope, and Low Energy X-ray Telescope, respectively. By combining all the data, the position and velocity of the Insight-HXMT are pinpointed to within 10 km (3ҩ and 10 m s-1 (3ҩ, respectively.   Calcium deficiency in hydroxyapatite and its drug delivery applications 期刊论文  OAI收割 MICRO & NANO LETTERS, 2018, 卷号: 13, 期号: 4, 页码: 562-564 作者:  Rajagopalan, Vijayaraghavan;  Koppala, Sivasankar;  Swamiappan, Sasikumar;  Gangarajula, Yuvaraj;  Xu, Lei   |  收藏  |  浏览/下载：48/0  |  提交时间：2019/06/20 Calcium Compounds  Bioceramics  Drug Delivery Systems  Drugs  Nanoparticles  Particle Size  Nanofabrication  Nanomedicine  Fourier Transform Infrared Spectra  Precipitation  Calcination  X-ray Diffraction  Scanning Electron Microscopy  X-ray Chemical Analysis  Nanoporous Materials  Porosity  Drug Delivery Applications  Calcium Deficient Hydroxyapatites  Precipitation Method  Calcined Samples  Fourier Transformation Infrared Spectroscopy  Powder X-ray Diffraction  Scanning Electron Microscopy  Energy-dispersive X-ray Spectroscopy  Phase Purity  Particle Size  Particle Shape  Hap Structure  Ciprofloxacin  Sustained Drug Release  Phosphate Buffer Solution  Porous Structure  [Ca10-x(Po4)(6)(Oh)(2)]
