Dissolved organic matter composition and mineral surface chemistry modulate organic retention and formation of mineral associated organic matter

The interaction between dissolved organic matter (DOM) and minerals governs OM stabilisation in soils. Heterogeneous composition of DOM and diverse mineral surface characteristics in soils make it challenging to determine reaction mechanisms at mineral-organic interfaces. To dete...

TrivalentAl Insertion into Layered-Oxide-DerivedPerovskite Oxynitrides for Defect-Controlled Dielectric Response

Abstract Al-containing perovskite oxynitrides, SrAl0.2M0.8O2.4N0.6 (M = Nb, Ta), were synthesized by ammonolysis of layered Sr5M4O15 precursors with α-Al2O3. This reaction demonstrates that the cation-insertion chemistry of layered-perovskite-derived oxynitrides can be extended t...
