Electronic Structure of Vanadium-Doped TiO2 of Both Anatase and Rutile Based on Density Functional Theory (DFT) Approach

open access: yesAlchemy, 2018
Study of the theoretical  approah to calculate the band structure and density of states (DOS) of vanadium-doped TiO2 of both anatase and rutile have been done. The first-principle calculations were done using supercell (2x1x1) method. The first-principle

High field strength element systematics and Lu-Hf & Sm-Nd garnet geochronology of orogenic eclogites [PDF]

open access: yes, 2008
Concerning the Bulk Silicate Earth (BSE), the depleted mantle and the continental crust are thought to balance the budget of refractory and lithophile elements, resulting in complementary trace element patterns.

Porosity through reduction in metal oxides [PDF]

open access: yes, 2008
Routes to porous materials with nanoscale dimensions have been investigated. In the first example presented, porous manganese oxide has been prepared by leaching Ni metal from a nickel-manganese oxide precursor via reduction.

Coatings on stainless steel for solid oxide fuel cell interconnects [PDF]

open access: yes, 2013
Enabling inexpensive and ubiquitous steels for use as solid oxide fuel cell interconnects has two major hurdles to overcome. Firstly, corrosion must be limited such that the interconnect can have longevity.

Band Gap Measurements of Nano-Meter Sized Rutile Thin Films

open access: yesNanomaterials, 2020
Thin Titanium films were fabricated on quartz substrates by radio frequency magnetron sputtering under high vacuum. Subsequent annealing at temperatures of 600 ∘C in air resulted in single-phase TiO2 with the structure of rutile, as X-ray diffraction ...

Adsorption of Water Vapour on Rutile and Silica-Coated Rutile

open access: yesAdsorption Science & Technology, 1986
Adsorption isotherms of water vapour have been determined at 25°C on pure rutile (surface area 22 m 2 .g −1 ) and on two samples of the rutile coated with different amounts of dense silica (0·6 & 2·6 wt% SiO 2
