Philippine Pottery: Its Origins, Influences, And What It Is

2021. 5. 24.  The discovery of a 3500-year-old secondary burial jar from the Manunggul Cave of Tabon Caves in Lipuun Point, Palawan proves that pottery in the Philippines started as early as the Neolithic period. Found in the early Sixties, the burial jar is incised with curvilinear scroll designs painted with hematite.

Hematite an overview ScienceDirect Topics

Iron(III) oxide, and, in particular, hematite (α-Fe 2 O 3), its most stable polymorph, is one of the most important functional materials for PEC water splitting photoanodes [5,8,11,18], thanks to its abundance, nontoxicity, economic viability, stability in aqueous mixtures, and suitable E G (≈ 2.0 eV) to absorb a significant solar spectrum fraction [11,29,69].

Hematite an overview ScienceDirect Topics

Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.

Effect of low-molecular-weight organic acids on hematite

2017. 4. 28.  Siderophores, as strong chelators specific to iron, have been intensively studied in relation to the facilitation of biological iron acquisition from iron oxides. In this study, the dissolution of hematite in the presence of the siderophore desferrioxamine B (DFOB) and three low-molecular-weight organic acids (LMWOAs, i.e., oxalic, citric, or malic acid) was investigated at three pH conditions

The molecular insights into protein adsorption on hematite

BSA lost the α-helix and gain β-sheets in the secondary structure during adsorption on hematite. BSA adsorption was maximum at pH 5, a value close to the BSA isoelectric point (~ pH 5), and lower at pH 4 and pH 7. Increasing ionic strength decreased to total BSA adsorption.

Peroxidase-Like Activity of Ferrihydrite and Hematite

2016. 10. 3.  The pH was an important factor for the catalytic degradation, since a maximum degradation of 24% was obtained at a pH of 3.6, while at pH of 8, up to 100% of MB degradation was obtained. According to the optimization experiments, the best conditions for degradation of MB using hematite NPs were pH 8, H 2 O 2 concentration of 0.45 mol/L, and NPs concentration of 5 g/L.

Effect of low-molecular-weight organic acids on hematite

Hematite dissolution was pH-dependent and LMWOA-specific. The adsorption of DFOB on hematite was significantly higher at pH 9.0 than at the other pH values. The adsorption of oxalic acid on hematite, however, showed a descending trend as pH was increased, and adsorption of citric and malic acids was not significantly affected by pH.
