Crystal structure and pale-yellow emitting properties of KGdDyBO solid solutions.

A new potassium dysprosium polyborate, KDyBO, has been prepared via the high-temperature molten salt method and structurally characterized by single-crystal X-ray diffraction analysis. The structure can be described as a three-dimensional framework composed of isolated bicyclic [BO] groups and Dy and K ions. The Fourier transform IR (FT-IR) and ultraviolet-visible (UV-Vis) spectra were investigated.

KEu(PO): hydrothermal synthesis, crystal structure and photoluminescence properties.

An anhydrous orthophosphate, KEu(PO) (tripotassium pentaeuropium hexaphosphate), has been prepared by a high-temperature solid-state reaction combined with hydrothermal synthesis, and its crystal structure was determined by single-crystal X-ray diffraction analysis (SC-XRD). The results show that the compound crystallizes in the monoclinic space group C2/c and the structure features a three-dimensional framework of [Eu(PO)], with the tunnel filled by K ions. The IR spectrum, UV-Vis spectrum and luminescence properties of polycrystalline samples of KEu(PO), annealed at temperatures of 650, 700, 750, 800 and 850 °C, were investigated.

[Vertical distribution characteristics and temporal stability of soil water in deep profile on the Loess Tableland, Northwest China.].

Study of impacts of land uses on spatiotemporal dynamics of soil water content (SWC) is of great significance for understanding the performance characteristics of regional water cycling under changing environment. Based on long-term located field observations, this paper explored the temporal dynamics of soil water in 0-15 m soil profile under four land use types on the Loess Tableland from September 2012 to December 2015. Results showed that the annually averaged SWCs over the 0-15 m soil profile for alfalfa field, fallow field, fertilized cropland and unfertilized cropland were 15.

Identification of the leprosy agent Mycobacterium lepromatosis in Singapore.

Background: A new leprosy-causing species, namely Mycobacterium lepromatosis, was discovered recently to be the cause of diffuse lepromatous leprosy (DLL) in Mexico. It is unknown whether this organism exists beyond Mexico.

Methods: We sought to determine the identity of the mycobacteria in the skin tissue of two patients from Singapore who died of DLL.
