Anhydrous sulfate minerals are abundant in the active fumaroles with highly oxidizing conditions on the scoria cones of the Tolbachik volcano. The mineral itelmenite, ideally Na2CuMg2(SO4)4, containing isomorphous admixture of Zn, was described in 2018, whereas glikinite, ideally Zn3O(SO4)2, was described in 2020. Synthetic analogs of both minerals...

Nd-doped TiO2 nanoparticles of different concentration are synthesized using a wet chemical route, followed by structural, optical and magnetic property examination. X-ray diffraction of the Nd-doped samples exhibits a tetragonal type anatase crystal structure similar to that of the pure TiO2. Crystallite size and strain of the nanoparticles are ca...

Iron (Fe) substituted nickel oxide (Ni1−xFexO) and manganese (Mn) substituted (Ni1−xMnxO) nanoparticles at x = 0.05 were prepared using solid-state reaction. The synthesized Ni1−xFexO and Ni1−xMnxO nanoparticles were annealed in vacuum at a pressure of 1 × 0–3 mbar at two different temperatures of 473 K and 673 K for 1 h. The influence of vacuum an...

Abstract During the Paleoproterozoic Era, the Brazilian cratons experienced orogenic events that modified the archean basement and sedimentary successions. In the southern São Francisco Craton, it can be recognized evidence of an orogenic event that happened between Rhyacian and Orosirian periods. It is related to the closure of an oceanic basin a...

A new organic–inorganic hybrid with the empirical formula [NH3single bondCH2single bondCOOH]CdCl3.H2O has been crystallised, and the structure was solved at room temperature (system (orthorhombic), space group (Pcam), unit parameters cell (a = 7.433(10) Å, b = 7.743(2) Å, c = 25.346(6) Å), volume 1458.76 (5) Å3), Z = 8). The asymmetric unit cell co...

Crystalline gallium (III) sulfide Ga2S3 samples have been prepared by mechanical-alloying instead of usual heating process. A safe, energy-efficient, and fast process of only 4 h of mechanosynthesis led to the formation of polycrystalline Ga2S3 from pure Ga and S as raw materials. X-ray diffraction measurements and Rietveld refinements show that th...

Food security has become an increasingly important challenge for all countries globally, particularly as the world population continues to grow and arable lands are diminishing due to urbanization. Water scarcity and lack of labor add extra negative influence on traditional agriculture and food production. The problem is getting worse in countries ...

Five samples of differently colored sodalite-group minerals from gem lazurite deposits were studied by means of electron microprobe and wet chemical analyses, infrared, Raman, electron spin resonance (ESR) and UV-Visible spectroscopy, and X-ray diffraction. Various extra-framework components (SO42−, S2− and Cl− anions, S3•−, S2•− and SO3•− radical ...
