Enhanced photocurrent density of hematite thin films
The hematite film on the surface of the FTO substrate annealed at 700 °C showed an enhanced photocurrent value with a maximum photocurrent of 0.39 mA cm −2 at 1.23 V vs. RHE under 1 sun illumination. This is a much enhanced photocurrent value of the hematite films than that of those annealed at temperatures lower than 700 °C.

2019-4-13 The results show that the density of the ore particles decreases by 15.1% at most along the progressive reduction process. Furthermore, the model results also indicate that heating, melting and reduction of the ore could lead to 6.63–9.37% swelling of the particles, which is mostly contributed by thermal expansion.

Density Specific Gravity Some Meteorite
Density Density is the term for how heavy an object is for its size.Density is usually expressed in units like grams per cubic centimeter (g/cc or g/cm 3), kilograms per cubic meter, pounds per cubic inch (cubic foot or cubic yard), or pounds per gallon. Rocks vary considerably in density, so the density of a rock is often a good identification tool and useful for distinguishing terrestrial ...

The Density of Common Rocks and Minerals -
2020-1-23 The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

When Density Functional Approximations Meet Iron
2016-9-3 Three density functional approximations (DFAs), PBE, PBE+U, and Heyd–Scuseria–Ernzerhof screened hybrid functional (HSE), were employed to investigate the geometric, electronic, magnetic, and thermodynamic properties of four iron oxides, namely, α-FeOOH, α-Fe2O3, Fe3O4, and FeO. Comparing our calculated results with available experimental data, we found that HSE (a = 0.15) (containing 15 ...
