This paper explores topics and techniques of prognostication as recorded in medieval Buddhist historical literature, with an emphasis on the Gāosēng zhuàn 高僧傳 (GSZ) and Xù gāosēng zhuàn 續高僧傳 (XGSZ). The paper first provides a short survey of how prognostication is treated in Chinese Buddhist translated texts. In these ‘canonical’ sources there is clear ambiguity over the use of supernatural powers: on the one hand, such practices are criticised as non-Buddhist or even heterodox; on the other, narratives on Śākyamuni’s former and present lives as well as accounts of other buddhas, bodhisattvas, and the Buddha’s disciples abound with descriptions of their special abilities, including knowledge of the future. In contrast, the GSZ and XGSZ display a clear standpoint concerning mantic practices and include them as integral aspects of monastics’ lives. The two texts articulate that the ability to predict the future and other supernatural powers are natural by-products of spiritual progress in the Buddhist context. This paper discusses the incorporation of various aspects of the Indian and Chinese traditions in monastics’ biographies, and investigates the inclusion of revelations of future events (for example, in dreams) and mantic techniques in these texts. In addition, it traces parallels to developments in non-Buddhist literature and outlines some significant differences between the GSZ and the XGSZ.

Abstract

A new supramolecular compound [Ni3(Hdatrz)6(sca)2(H2O)4]sca·11H2O (Hdatrz = 3,5-diamino-1,2,4-triazole, H2sca = succinic acid) was synthesized and characterized by elemental analysis, single crystal X-ray diffraction and thermogravimetric analysis. X-ray structural analysis reveals that the crystal is triclinic, space group P − 1 with lattice parameters a = 10.192(2) Å, b = 11.671(2) Å, c = 13.600(3) Å, β = 68.086(3)°, Z = 1, D c = 1.689 g/cm−3, F(000) = 728. The enthalpy change of the reaction of formation in water was determined by an RD496–CK2000 microcalorimeter at 25 °C with the value of −23.71 ± 0.023 kJ mol−1. In addition, the thermodynamics of the reaction of formation in water for the compound was investigated by changing the temperature of the reaction and the fundamental parameters k, E, n, , and were obtained.

Abstract

Polyester powder coating modified with 2 mass% of rutile nano-sized titanium dioxide (nano-TiO2) was prepared by melt-blend extrusion method. The nano-TiO2 dispersion state in the powder coating matrix was analyzed by field emission scanning electron microscopy (FE-SEM), which presented a well dispersion of modified nano-TiO2 in the polyester powder coating. The effect of nano-TiO2 on the curing of polyester powder coating was investigated by differential scanning calorimeter (DSC). Kissinger and Crane methods were used to study the activation energy (E) and reaction order (n) of the coating. The results indicated that 2 mass% of nano-TiO2 additive played a prompting role in the curing of polyester powder coatings, due to the hydroxyl functional groups existed on the surface of nano-TiO2. Furthermore, real-time Fourier transform infrared (FT-IR) spectroscopy with a heating cell was also employed to record the curing actions, of which results were consistent with the DSC experiments.

Abstract  

The effects of aluminum (Al) and nickel (Ni) powders of various grain sizes on the thermal decomposition of ammonium perchlorate (AP) were investigated by TG and DSC in a dynamic nitrogen atmosphere. The TG results show that Al powders have no effect on the thermal decomposition of AP at conventional grain size, while the nanometer-sized Ni powders (n-Ni) have a great influence on the thermal decomposition of AP with conventional and superfine grain size. The results obtained by DSC and an in situ FTIR analysis of the solid residues confirmed the promoting effects of n-Ni. The effects of n-Ni have been ascribed to its enhancement on the gas phase reactions during the second step decomposition of conventional grain size AP.
