Bobtraillite from Gejiu hyperagpaitic nepheline syenite, southwestern China:new occurrence and crystal structure
No full textA second occurrence of bobtraillite is described from the Gejiu nepheline syenite, southwestern China. The extremely rare and complex boron-bearing zirconium silicate is associated with albite, orthoclase, jadeite, fluorite, andradite, titanite, as well as other REE and zirconium-bearing minerals, catapleiite, moxuanxueite, l & aring;venite, eudialyte, britholite-(Ce), and calcioancylite-(La). The EMP and LA-ICP-MS analyses of the studied material give an empirical formula: (Na9.70Li0.42K0.08?(1.80))sigma(12.00)(Sr10.61Ca1.14Fe0.07?(0.18))sigma(12.00) (Zr12.87Ti0.53Nb0.31REE0.08Y0.06U0.02Th0.01?(0.12))sigma(14.00)(Si42.41B5.59Al0.02)sigma O-48.02(132)(OH)(12.12)H2O. Bobtraillite is trigonal, with space group P (sic)3c 1, a = 19.6977(6), c = 9.9770(3) & Aring;, V = 3352.4(2) & Aring;3, Z = 1. Single-crystal structure refinement revealed that all sodium occupies the Na(1) and Na(2) sites; the site occupancy of these two positions is 0.835(18) and 0.15(2), respectively, suggesting that Na(1) site is Na dominant, while Na(2) is a vacancy-dominant site. The [8]-coordinated site has been assigned to Sr and Ca, with free occupancy factors, 0.874(10) and 0.126(10), respectively. These new data indicate that the ideal formula of bobtraillite could be written as (Na,?)(12)(?,Na)(12)Sr12Zr14(Si3O9)(10)[Si2BO7(OH)(2)]6.12H(2)O

No full textA Comprehensive Correction of the Gaia DR3 XP Spectra
No full textBy combining spectra from the CALSPEC and NGSL, as well as spectroscopic data from the LAMOST Data Release 7 (DR7), we have analyzed and corrected the systematic errors of the Gaia DR3 BP/RP (XP) spectra. The errors depend on the normalized spectral energy distribution (simplified by two independent “colors”) and G magnitude. Our corrections are applicable in the range of approximately −0.5 < BP − RP < 2, 3 < G < 17.5, and E ( B − V ) < 0.8. To validate our correction, we conduct independent tests by comparisons with the MILES and LEMONY spectra. The results demonstrate that the systematic errors of BP − RP and G have been effectively corrected, especially in the near-ultraviolet. The consistency between the corrected Gaia XP spectra and the MILES and LEMONY is better than 2% in the wavelength range of 336–400 nm and 1% in redder wavelengths. A global absolute calibration is also carried out by comparing the synthetic Gaia photometry from the corrected XP spectra with the corrected Gaia DR3 photometry. Our study opens up new possibilities for using XP spectra in many fields. A Python package is publicly available to do the corrections (doi: https://doi.org/10.12149/101375 or https://github.com/HiromonGON/GaiaXPcorrection )
First-principles calculations of band offsets of Al xGa 1-xP-GaP(001) heterostructures
No full textA first-principles pseudopotential method combined with the virtual-crystal approximation (VCA) is used to calculate band offsets of Al xGa 1-xP-GaP(001) heterostructures. It was found that both the valence and conduction band offsets vary linearly with the alloy composition. Our results are in good agreement with the experimental data.link_to_subscribed_fulltex
, a new member of the ancylite group from Gejiu nepheline syenite, Yunnan Province, China
No full textCalcioancylite-(La), ideally (La,Ca)(2)(CO3)(2)(OH,H2O)(2), has been discovered from nepheline syenite of the Gejiu alkaline complex in the Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, China. The mineral occurs as aggregates of subhedral grains, and the size of single crystals varies between 5-20 mu m. Calcioancylite-(La) is colourless to pale pinkish grey and has transparent to translucent lustre. It is brittle with a Mohs hardness of 4. The calculated density is 4.324 g/cm(3). The mineral is biaxial (-), with alpha =1.662, beta = 1.730, gamma = 1.771, 2V(meas.) = 70 degrees(1) and 2V(calc.) = 73 degrees. Electron microprobe analysis for holotype material yielded an empirical formula of (La0.58Ce0.55Pr0.14Nd0.10Ca0.39Sr0.20K0.04)(Sigma 2.00)(CO3)(2)[(OH)(1.25)F-0.06 center dot 0.69H(2)O](Sigma 2.00). Calcioancylite-(La) is orthorhombic, with space group Pmcn, a = 5.0253(3) angstrom, b = 8.5152(6) angstrom, c = 7.2717(6) angstrom, V = 311.17(4) angstrom(3) and Z = 2. By using single-crystal X-ray diffraction, the crystal structure has been determined and refined to a final R-1 = 0.0652 on the basis of 347 independent reflections (I > 2 sigma). The seven strongest powder X-ray diffraction lines [d in angstrom (I) (hkl)] are: 2.334 (100) (013), 2.970 (80) (121), 4.334 (75) (110), 3.678 (68) (111), 2.517 (55) (200), 2.647 (47) (031) and 2.077 (44) (221). Calcioancylite-(La) is the La-analogue of calcioancylite-(Ce) and is a new member of ancylite-group minerals. The mineral and its name have been approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association (IMA2021-090)
Han dai Gu wen shang shu jing zi yan jiu
No full textBased on these fragments, this dissertation first makes an attempt to clarify the issues involving the Gu Wen Shang Shu that was discovered in the Kong's wall, as reported in various documents of the Han Dynasty. It then proceeds to discuss the characteristics and the origins of the "archaic scripts" in the Shuo-wen Jie-zi and the Stone Classics in Three Scripts of the Wei Dynasty, as these two texts and the script of Gu Wen Shang Shu are closely related.Finally, by examining the discrepancies between the quotations of the Shang Shu in the Shuo-wen Jie-zi and the version of Ma Rong and Zheng Xuan, this dissertation constructs the argument that such discrepancies are perhaps the result of the interpretative replacement of characters which was, after all, a common method of teaching employed by gu wen scholars of the Eastern Han.It further deals with the argument of the "li-shu" transliteration (li gu ding), and through a detailed analysis of the expressions and terms used in the text, it expounds the view that the li-shu transliteration of the Gu Wen Shang Shu was non-existent in the Han Dynasty, let alone a so called li-shu transliterated version.Seeking to challenge this viewpoint, the author of this dissertation has made a close examination of the Gu Wen Shang Shu and has discovered that it was actually written in "li-shu", rather than in archaic script. Through a survey of relevant philological issues, the arguments are presented in this dissertation.The controversy surrounding the opposition between the archaic and vernacular scripts (jin gu wen) of the Han Dynasty is one of the most complex issues in Chinese philology. Scholars have yet to come to a consensus on which script the Gu Wen Shang Shu (The Book of History Written in Archaic Script) was written. For a long time, a popular view has been that the difference between "jin wen" (vernacular script: li-shu) and "gu wen" (archaic script) lies in the types of script used, as the so-called Gu Wen Shang Shu is believed to have been written in archaic script.The issue of script of Gu Wen Shang Shu has been a significant topic in Chinese philology. Moreover, the controversy over the archaic script and the contemporary script of the Han Dynasty is very much about the Shang Shu. An understanding of this issue is crucial in resolving problems confronting other archaic texts.Though the original text of the Gu Wen Shang Shu is no longer extant, there are a few surviving fragments in the quotations of the Shang Shu in the Shuo-wen Jie-zi, the "archaic scripts" in the Stone Classics in Three Scripts (San-ti Shi-jing), the "li-shu" transliteration (li gu ding) of the Shang Shu and the quotations of the Gu Wen Shang Shu of Ma Bong and Zheng Xuan in the Jin-dian Shi-wen.蘇春暉.論文(哲學博士)--香港中文大學, 2007.參考文獻(p. i-xvi).Adviser: Chan Hung Kan.Source: Dissertation Abstracts International, Volume: 69-01, Section: A, page: 0198.Electronic reproduction.

The Ancient Chinese Concepts of Shang 商 and Gu 賈 : Their Meaning and Historical Background
No full textIt has popularly been understood that the characters shang 商 and gu 賈 which express ideas of commerce and merchants can be separated in meaning such that shang refers to itinerant merchants (xingshang 行商) and gu refers to stationary merchants or shopkeepers (zuogu 坐賈). However, they cannot be restricted to these meanings. They were at times used interchangeably, and each author had a particular tendency in their usage. Moreover, in the Qin and Han periods, the words gu and guren 賈人 were technical terms used in legal documents to indicate commerce and merchants respectively. Without regard to this actual situation in his own time, Ban Gu 班固. in the Commerce chapter of his work "Explanations of the White Tiger Palace." asserted that shang meant "moving" (xing 行) and gu meant "stationary" (zhi 止). This was because he only considered the description recorded in the Zuozhuan and the Zhouli. His commerce chapter was written with the intention of showing that the Old Text Theory was superior to the competing New Text Theory. At the end of the Later Han, the idea that shang meant "itinerant" and gu meant "stationary" became an established theory due to the work of Zheng Xuan 鄭玄. Nevertheless, this distinction was not strictly followed even in later periods. In these periods, technical terms in legal documents indicating merchants changed from shanggu 商賈 in the Wei and Jin to just Shang in the Six Dynasty period. This latter term was then inherited by the Sui and Tang
