Luminescence in sulfides : a rich history and a bright future [PDF]

open access: yes, 2010
Sulfide-based luminescent materials have attracted a lot of attention for a wide range of photo-, cathodo- and electroluminescent applications. Upon doping with Ce3+ and Eu2+, the luminescence can be varied over the entire visible region by appropriately

Spitzer IRS Spectroscopy of the 10 Myr-old EF Cha Debris Disk: Evidence for Phyllosilicate-Rich Dust in the Terrestrial Zone [PDF]

open access: yes, 2011
We describe Spitzer IRS spectroscopic observations of the 10 Myr-old star, EF Cha. Compositional modeling of the spectra from 5 {\mu}m to 35 {\mu}m confirms that it is surrounded by a luminous debris disk with LD/L\star ~ 10-3, containing dust with ...

Percolation Behavior of a Sulfide Electrolyte–Carbon Additive Matrix for Composite Cathodes in All-Solid-State Batteries

open access: yesBatteries, 2023
To achieve high energy densities with sufficient cycling performance in all-solid-state batteries, the fraction of active material has to be maximized while maintaining ionic and electronic conduction throughout the composite cathode.

Clasts in the CM2 carbonaceous chondrite Lonewolf Nunataks 94101: evidence for aqueous alteration prior to complex mixing [PDF]

open access: yes, 2013
Clasts in the CM2 carbonaceous chondrite Lonewolf Nunataks (LON) 94101 have been characterized using scanning and transmission electron microscopy and electron microprobe analysis to determine their degrees of aqueous alteration, and the timing of ...

Electron self-exchange activation parameters of diethyl sulfide and tetrahydrothiophene

open access: yesBeilstein Journal of Organic Chemistry, 2013
Electron transfer between the title compounds and their radical cations, which were generated by photoinduced electron transfer from the sulfides to excited 2,4,6-triphenylpyrylium cations, was investigated by time-resolved measurements of chemically ...

ENRICHMENT OF MASSIVE SULFIDES FROM THE SEMENOV HYDROTHERMAL CLUSTER (MID-ATLANTIC RIDGE) IN BARITE: A RESULT OF E-MORB INVOLVEMENT AND MAGMATIC CONTRIBUTION [PDF]

open access: yesМинералогия
The paper reviews and compares the barite findings in hydrothermal fields of the midoceanic ridges. The genetic significance of barite is considered for the Semenov hydrothermal sulfide cluster associated with an oceanic core complex (OCC) at 13°30′ N of

Polyoxovanadate-Based Cyclomatrix Polyphosphazene Microspheres as Efficient Heterogeneous Catalysts for the Selective Oxidation and Desulfurization of Sulfides

open access: yesMolecules, 2022
The [V6O13]2− cluster is successfully immobilized to the polymeric framework of cyclomatrix polyphosphazene via the facile precipitation polymerization between the phenol group symmetrically modified [V6O13]2− and hexachlorocyclotriphosphazene.
