... of siderite nanocrystals. The siderite microspheres so obtained were then used as solid precursor minerals to form secondary magnetite through oxygen-limited thermolysis at 300 °C. The thermolysis experiments demonstrate the possibility that the size and morphology of secondary magnetite particles...

Lerner Abstract Phase and morphological changes during thermolysis of Mg 4 Al 2 (OH) 12 CO 3 .eta H 2 O and Zn 6 Al 2 (OH) 16 CO 3 .eta H 2 O layered double hydroxides (LDH) and their nanocomposites with poly(styrene sulfonate) (PSS) are studied...

... molecular alkylbenzene, alkylphenol, and phenylalkane fragments) in kerogen. Since the studied kerogen is rich in esters, it is worth performing alkaline hydrolysis of its macromolecules (ester saponification) before their thermolysis, which inevitably distorts the initial structure of molecular skeletons...

... to reflect the termination of hydrocarbon generation from kerogen and further thermolysis of residual bitumens, including their asphaltene components. This explains the low values of maturity biomarker indicators corresponding to the apocatagenesis grade, since in this case they reflect the composition...
