Nb₂O₅ nanorod crystallized on diatomite substrate through a hydrothermal method.

Specific surface area of Nb₂O₅-modified diatomite increased from 28 m²/g to 153 m²/g.

The adsorption capacity increased consequently to 115 mg/g towards Cr(VI).

Under UV light irradiation, surface adsorbed Cr(VI) could be photoreduced to Cr(III).

The modified diatomite exhibited a synergistic effect of adsorption and photoreduction.

The lifting cylinder test is introduced for cohesive-material DEM calibration.

There are four characteristic phases of flow behaviour when lifting the cylinder.

Characteristic phases are independent of the cylinder size and lifting velocity.

Convex bending and collapse of a material column are introduced as new references.

DEM parameters are calibrated by measuring convex bending via an analysis algorithm.
