Petrological and geochemical studies of lamproites can provide useful insights into the
nature of their lithospheric mantle sources, but their geochemical and mineralogical diversity …

In this study, alkali and bifunctional catalysts were synthesized for waste frying oil methyl
ester (WFOME) synthesis. Coffee husk (CH) and CH blended with Eragrostis tef straw …

Phase relations in the carbonate constituent of mafic and ultramafic suites are decisive in the
deep carbon cycle and partial melting in the Earth's mantle. Here we present an …

The catalytic activity of the KNO 3 and ZrO (NO 3) 2· H 2 O modified coffee husk ash alkali
(KN/CHA) and bifunctional (ZN/CHA) catalysts was investigated for triglyceride-containing …

Carbonate micro inclusions with abnormally high K2O appear in diamonds worldwide.
However, the precise determination of their chemical and phase compositions is …

In this study, the influences of different parameters on the products of K-Ca synergistically
catalyzed biomass pyrolysis and the possible chemical reactions during the process were …

Inclusions of former alkaline carbonate melts occur in igneous minerals, mantle xenoliths,
and diamonds from kimberlites and lamproites. However, the identification of most daughter …

The proposed work highlights the synthesis of WO 3/Ag 2 CO 3 composite mediated with
rGO by hydrothermal cum in-situ chemical precipitation method. The optical studies reveal …

Density functional theory methods with the B3LYP hybrid functional and the basis of a linear
combination of localized atomic orbitals of the CRYSTAL17 program code were used to …

Liquid immiscibility plays an important role in the formation of carbonatites and associated
alkaline Si-undersaturated magmas. Experiments in the sodium carbonate-aluminosilicate …
