Synthesis and characterisation of iron oxides: Effect of calcination temperature and their application as inorganic pigment

Coloration Technology, Volume 142, Issue 2, Page 222-235, April 2026.
Abstract This research aimed to investigate the effect of calcination temperature on the phase, morphological and optical properties of iron oxides: hematite (α‐Fe₂O₃), magnetite (Fe₃O₄) and goethite (α‐FeOOH), synthesised by co‐precipitation, aiming at their applications as pigments.

Dynamic Sinking and Surface‐Area Based Decay Modeling Reduce Estimates of Gelatinous Zooplankton‐Mediated Carbon Export to the Deep Sea

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Gelatinous zooplankton (GZ) have been proposed as a potentially important but largely overlooked contributor to the biological carbon pump. However, estimates of GZ‐derived carbon transfer efficiency to the ocean floor reflect uncertainties in key parameters that govern carbon export, leading to contrasting interpretations of the role of GZ in
