AbstractWith exquisite design and unique style, the painted sculptures of Tutang Buddha and two attendants Buddha in Jingyin Temple are precious cultural heritages of China. The sculpture of Tutang Buddha, which was carved from a mound and painted by ancient craftsmen, was rarely found in ancient China. However, due to natural and human factors, the sculptures were severely damaged. Obviously, they require urgent and appropriate protection and restoration. In this study, samples taken from the sculptures were analysed through multiple analytical techniques, including scanning electron microscopy with energy dispersive spectrometry (SEM–EDS), Raman spectroscopy, X-ray diffraction (XRD), optical microscopy (OM) and granulometry. The analysis results enable us to infer the techniques used by the craftsmen in making the sculptures and provide a reliable evidence for the conservation and future protection of these and similar sculptures.

Abstract The painted statues of Tutang Buddha and two attendants Buddha in Jingyin Temple, with exquisite design and unique style, are precious cultural heritages of China. The statue of Tutang Buddha which was carved from a mound and painted by ancient craftsmen, is rarely found in ancient China. However, on account of the influence of natural factors and artificial harms, the statues were severly damaged. Obviously, it requires urgently carrying out appropriate protection and restoration of the statues. In this study, the samples taken from the statues were analysed by multiple analytical techniques, including scanning electron microscopy with energy dispersive spectrometry (SEM-EDS), Raman spectroscopy, X-ray diffraction (XRD), biological microscopy and particle size analysis. The analysis enabled us to infer the techniques used by the creators in making the statues. This research provides reliable evidence for the conservation and future protection of these and similar statues.

In this study, the effect of rotational speed on the microstructure and weldability of AISI1030 steel and AISI304 stainless steel welded by friction welding method were investigated experimentally. The weld joints were manufactured with rotational speed (1500, 1600, 1700, 1800, 1900, and 2000 rev/min.), friction pressure (40 MPa), forging pressure (60 MPa), forging time (4 s), and friction time (6 s). After the FW process, the microstructures of the weld interfaces were analyzed by optic microscopy, scanning electron microscopy, energy dispersive spectrometry, elemental mapping, and X-ray diffraction analysis. Moreover, the weld strength was analyzed by tensile test, and the fracture behavior was investigated with scanning electron microscopy. The results indicated that increased rotational speed had a significant effect on the microstructure and weldability.

The effect of Ti and Sb elements addition on the microstructures and corrosion resistance of hot-dip galvanized Zn-11Al-3Mg alloy was investigated by scanning electron microscopy (SEM) equipped with energy dispersive spectrometry (EDS), X-ray diffraction (XRD) and Electrochemical workstation, respectively. Results showed that the grain size of the alloy was obviously refined with the addition of Ti and Sb elements, due to Al3Ti phase as the nucleation substrate resulted in the transformation of Al-rich phase from dendrite to petal-like. In addition, the pitting corrosion resistance of the alloy has been significantly enhanced.

Mg2Ni1-xCux (x = 0, 0.2, 0.4) and Mg2Ni1-yCoy (y = 0, 0.2, 0.4) were successfully synthesized via two steps: induction melting and then ball milling. The component and microstructure of the alloys were determined with x-ray diffraction (XRD) and scanning electron microscopy/x-ray energy-dispersive spectrometry (SEM/XEDS). Mg2Ni phase was observed in all 5 alloys. When the amount of Cu was increased, it led to the formation of phase from Mg2Cu to Cu11Mg10Ni9. Co2Mg was detected in the Co-containing alloys. The hydrogen absorption/desorption properties were tested with p-C-T measurement apparatus, and the results showed that the gaseous storage properties of the alloys were improved by the addition of Cu or Co.

Parnaíba Basin

ABSTRACT: Paleozoic sandstones of the Parnaíba Basin, in addition to hosting opal deposits, also have occurrences of chalcedonies with potential for mineral and ornamental handicrafts, in addition to assisting the understanding of the geological evolution of the basin. However, the chalcedonies were not investigated yet, and this study intended to fulfill this gap by the investigation of the chalcedonies of Calçadinha in Piauí. Fieldwork, microtexturals analysis, X-ray diffraction and scanning electron microscopy with energy dispersive spectrometry, chemical analysis, and gemological assessments were developed. Four distinct types of chalcedonies have been distinguished. They stand out for their well distribution of Fe and Mn dendrites, which involves opal nodules, and contains microcavities with well-formed microcrystalline quartz, nontronite, and palygorskite. The mesoscopic features of these chalcedonies and cabochon and free forms cutting show potential for use in mineral crafts and semi-jewels. As expected, the chalcedonies are dominated by high contents of SiO2, besides the low and variable contents of Al2O3, Fe2O3, MgO, and TiO2. Among trace elements that show high Ba contents, bound in barite, seem also to be a geochemical signature of the country sandstones in Parnaíba basin. These chalcedonies were formed during the partial solubilization of SiO2 of sandstones, which was promoted during their tectonic formation in faults and fractures zones.

ABSTRACTThe powdered contents of 17 Late Roman and Byzantine glass vessels used to hold cosmetic eye-paints (kohl) were analyzed. The principal analytical techniques employed were X-ray diffraction, Fourier-transform infrared spectrometry, X-ray fluorescence, and scanning electron microscopy. The materials detected are described, indicating those which may have been used as kohl. Also reported are analytical results from a solid chunk of material surrounding a fragment of a metal rod, also obtained from a kohl vessel.
