    In:  Supplement to: Chen, J S; Sun, X X; Gu, W Z; Tan, H B; Rao, W B; Dong, H Z; Liu, X Y; Su, Z G (2012): Isotopic and hydrochemical data to restrict the origin of the groundwater in the Badain Jaran Desert, Northern China. Geokhimiya, 2012, 50(5), 502-512, Geochemistry International, 50(5), 455-465, https://doi.org/10.1134/S0016702912030044

    Description: Despite its extreme aridity the Badain Jaran Desert is rich in groundwater. In the southeastern part of this desert it is characterized by coexistence of high megadunes and a great number of lakes. Deuterium and oxygen 18 isotope compositions as well as hydrochemistry of groundwater, lake water, soil water and river water were investigated in detail to gain an insight into their relationships and the origin of the groundwater. The results show that the groundwater and the lake water are genetically related, but unrelated to local precipitation and the leakage of Heine River at the northern slope of the Qilian mountain. dD and d18O values of deep soil water (deeper than 40 cm) and groundwater plot on the same evaporation line E11, which shows that they have the same recharge source. The point of intersection between E11 and LMWL suggests that the groundwater originates from a water resource, which has a weighted mean value that is lighter by some 6 per mil d18O than local precipitation in Badain Jaran Desert. 3H data of water samples show that the groundwater in the Badain Jaran Desert originates from water recharged after the nuclear test. The deep fault zone underground maybe a water circulation channel based on helium analysis of groundwater. The result has guiding significance to rational exploitation and utilization of the local groundwater.

    Notes: A model, so-called heterogeneous two-dimensional (2D) nucleation model, is presented to describe the effect of foreign particles on the growth and surface instability of growing crystals. The occurrence of foreign bodies on growing surfaces of crystals will serve as precursors for heterogeneous 2D nucleation, so that it will promote rapid growth at relatively low supersaturations at the regions where the foreign particles are in contact with the crystal surface. At high supersaturations, due to the limitation of effective transport, heterogeneous 2D nucleation will become kinetically unfavourable. Then, foreign particles have less or no effect on crystal growth. To check the model, the theoretical results are confronted with experimental ones. A novel phenomenon of a needlelike pattern of surface instability caused by solid particle induced growth was observed for the first time for naphthalene crystals grown from the melt. This particulate-induced surface instability occurs in a completely different regime of G/V compared to the dendriticlike surface instability, which turns out to be in excellent agreement with our prediction. © 2000 American Institute of Physics.

    Notes: The generic heterogeneous effect of foreign particles on three dimensional nucleation was examined both theoretically and experimentally. It shows that the nucleation observed under normal conditions includes a sequence of progressive heterogeneous processes, characterized by different interfacial correlation function f(m,x)s. At low supersaturations, nucleation will be controlled by the process with a small interfacial correlation function f(m,x), which results from a strong interaction and good structural match between the foreign bodies and the crystallizing phase. At high supersaturations, nucleation on foreign particles having a weak interaction and poor structural match with the crystallizing phase (f(m,x)→1) will govern the kinetics. This frequently leads to the false identification of homogeneous nucleation. Genuine homogeneous nucleation, which is the up-limit of heterogeneous nucleation, may not be easily achievable under gravity. In order to check these results, the prediction is confronted with nucleation experiments of some organic and inorganic crystals. The results are in excellent agreement with the theory. © 2000 American Institute of Physics.

    Notes: Despite the relevance to most aspects of crystallization, a comprehensive understanding of the kinetics of heterogeneous nucleation has not been well established yet. In this paper, a new kinetic model based on the "steady-state" approach will be put forward to describe both heterogeneous and homogeneous nucleation. As a key point in this model, the effect of foreign particles on both the nucleation barrier, the "chain reaction" process and the transport of structural units is taken into account. Ranging from low to high supersaturations, heterogeneous nucleation plays a more comprehensive role in nucleation than we expected, depending on the size of foreign particles and the interaction and structural matching between foreign particles and the nucleating phase. It follows that genuine homogeneous nucleation may only be possible at very high supersaturations, and can become easier when convection is eliminated. The results have been verified by the CaCO3 nucleation experiments. This general model allows us to describe many unexpected nucleation phenomena for the first time, and will have significant impact on the control of nucleation, understanding of crystallization in microgravity, the measurement of the crystal–fluid interfacial tension, and crystallization in general. © 1999 American Institute of Physics.
