In the past couple of decades, the laser-heated diamond anvil cell (combined with in situ
techniques) has become an extensively used tool for studying pressure-temperature …

Iron oxide compounds have naturally formed during the whole of Earth's history. Synthetic
compositions with iron oxides are produced with the use of various techniques and widely …

The distribution, accumulation and circulation of oxygen and hydrogen in Earth's interior
dictate the geochemical evolution of the hydrosphere, atmosphere and biosphere. The …

Although chemically very simple, Fe2O3 is known to undergo a series of enigmatic
structural, electronic and magnetic transformations at high pressures and high temperatures …

The nature and extent of Earth's deep carbon cycle remains uncertain. This chapter
considers high-pressure carbon-bearing minerals, including those of Earth's mantle and …

Hydrous minerals in subducted crust can transport large amounts of water into Earth's deep
mantle. Our laboratory experiments revealed the surprising pressure-induced chemistry that …

In the present study, iron oxide nanoparticles (FeONPs) were firstly synthesized using non-
edible peel extracts of Citrus paradisi, which is abundantly available in the Andean Region …

Here we report on the impact of reducing the crystalline size on the structural and magnetic
properties of γ-Fe2O3 maghemite nanoparticles. A set of polycrystalline specimens with …

The diamond anvil cell (DAC) technique combined with laser heating is one of the major
methods for studying materials at high pressure and high temperature conditions. In this …

The iron-oxygen system is the most important reference of rocks' redox state. Even as minor
components, iron oxides can play a critical role in redox equilibria, which affect the …
