Durable Thin‐Film Porous Transport Electrodes for High Current Density PEM Water Electrolysis [PDF]

open access: yesAdvanced Science
Proton exchange membrane water electrolyzers rely on relatively expensive Ir‐based catalysts for efficient and durable hydrogen production. To reduce system costs, Ir loadings can be reduced if performance and durability are maintained.

Physiological responses of Spirulina platensis to nanoparticles of TiO2 and citrate [PDF]

open access: yesZīst/shināsī-i Giyāhī-i Īrān, 2022
In order to investigate the stimulating effect of TiO2 nanoparticles on the growth rate and the increase of some metabolites in the microalgae Spirulina platensis, the anatase and rutile forms of the TiO2 nanoparticle were compared to the bulk form, in ...

Mnemonic Rutile–Rutile Interfaces Triggering Spontaneous Dissociation of Water

open access: yesAdvanced Materials, 2023
AbstractWater interaction with mineral surfaces is a complex living system decisive for any photocatalytic process. Resolving the atomistic structure of mineral–water interfaces is thus crucial for understanding these processes. Fibrous rutile TiO2, grown hydrothermally on twinned rutile seeds under acidic conditions, is studied in terms of interface ...

Inner-sphere complexation of cations at the rutile-water interface: A concise surface structural interpretation with the CD and MUSIC model [PDF]

open access: yes, 2009
Acid–base reactivity and ion-interaction between mineral surfaces and aqueous solutions is most frequently investigated at the macroscopic scale as a function of pH.

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 ...

Identification of TiO2 Polymorphs of the Bauxite Deposit in Central Guangxi by Laser Raman Spectroscopy

open access: yesYankuang ceshi, 2022
BACKGROUND Rutile, anatase and brookite are TiO2 polymorphs. In the rutile in-situ U-Pb dating, rutile was determined primarily on electron microprobe data and cathodoluminescence images, while these methods sometimes could not effectively distinguish ...

Timing of late Palaeoproterozoic metamorphism in the northern Belomorian Belt, White Sea region: Conclusions from U-Pb isotopic data and P-T evidence [PDF]

open access: yesBulletin of the Geological Society of Finland, 2001
Brilliant-looking zircon crystals from a garnet-amphibolitic, metamorphosed mafic dyke at Lyagkomina in the Lake Kovdozero area, northern Belomorian Belt, most probably mark the 1875±4 Ma age of peak late Palaeoproterozoic regional metamorphism which ...

Structural, morphological and photocatalytic properties of TiO2 obtained by thermolytic decomposition of the [Ti(OH2)6]3+•3Cl¯ aquacomplex

open access: yesФізика і хімія твердого тіла, 2022
Thermolytic decomposition in a chloride-acid medium of a titanium aquacomplex precursor solution [Ti(OH2)6]3+•3Cl¯ as a result of its boiling at a temperature of (110-114) 0С is accompanied by precursor hydrolysis and the formation of hydrate molecules ...
