Effect of flow resistance in open rectangular channel [PDF]
, 2016 The determination of flow resistance for open channels remains a challenge in practices. In this research, an experimental study was carried out to investigate the hydraulic roughness characteristics in an open channel.

Selectivity of Benzyl Hydroxamic Acid in the Flotation of Ilmenite
Frontiers in Chemistry, 2019 The decreased ground size of ilmenite-bearing ores challenges the selectivity of collectors of ilmenite. Taking advantage of flotation tests and density functional theory (DFT), the selectivity of benzyl hydroxamic acid (BHA) and the adsorption mechanism

Abundance and Partitioning of OH in a High-pressure Magmatic System: Megacrysts from the Monastery Kimberlite, South Africa [PDF]
, 2004 Concentrations of OH, and major and trace elements were determined in a suite of mantle-derived megacrysts that represent the crystallization products of a kimberlite-like magma at ~5 GPa and ~1400–1100°C.

Shock compression of ilmenite [PDF]
Journal of Geophysical Research, 1976 Single- and reflected-shock compression measurements on single-crystal ilmenite (FeTiO_3) to pressures of 635 and 930 kbar, respectively, demonstrate anomalously large compressions above ∼320 kbar and imply the onset of one or more major phase changes at this pressure level which continue to occur to at least ∼600 kbar.

Nano-ilmenite FeTiO3: Synthesis and characterization [PDF]
Journal of Magnetism and Magnetic Materials, 2013 In general, ilmenite FeTiO3 is synthesized by solid-state reaction at very high pressure and high temperature. Synthesis of FeTiO3 is not an easy task as the Fe2þ ions are not stable. Therefore, it is really challenging to prepare this material. In this work nano-ilmenite FeTiO3 was synthesized by the sol–gel method.
