A novel method for synthesis of CaB₄O₇compound using ammonium pentaborate

Facile route for synthesis of strontium hexaborate crystalline powders

“…The strontium source was SrCO 3 (99.99% Merck company). Homemade ammonium pentaborate (APB) (NH 4 B 5 O 8 .4H 2 O) through a hot solution 24 was employed. Moreover, B 2 O 3 (99.99% Merck company) was utilized as the source of boron.…”

Boron in Prebiological Evolution

“…The number of calcium borate minerals is vast and, typically, they contain a very limited number of ions [100–112] . New calcium borate compounds have been obtained under synthetic conditions, relatable to prebiotic environments [113–115] . Studies with other calcium and borate minerals could contribute for additional clarification of some prebiological steps of evolution.…”

Efficient route for preparation of Nd3+ doped Y2O3 nanoparticles at intermediate temperature

“…Also, this process is simple, has high yield, high selectivity, and less pollution. It must be noted that the solid-state process is very slow, needs a lot of energy, and occurs at high temperatures [ [36] , [37] , [38] , [39] , [40] ]. In this article, for the first time, an optimized solid-state process for Nd 3+ -doped yttrium oxide nanoparticles was developed at a much lower temperature and in less time than other reported procedures, and then their optical and structural properties were characterized by various methods such as X-ray diffraction, Fourier transform infrared (FTIR), field emission scanning electron microscope (FE-SEM), transmission electron microscopy (TEM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Energy-dispersive X-ray analysis (EDAX) and Selected Area Electron Diffraction (SAED) pattern.…”
