Photolytic Hazes in the Atmosphere of 51 Eri b [PDF]

open access: yes, 2016
We use a 1D model to address photochemistry and possible haze formation in the irradiated warm Jupiter, 51 Eridani b. The intended focus was to be carbon, but sulfur photochemistry turns out to be important.

Elemental Abundances of Blue Compact Dwarfs from mid-IR Spectroscopy with Spitzer [PDF]

open access: yes, 2007
We present a study of elemental abundances in a sample of thirteen Blue Compact Dwarf (BCD) galaxies, using the $\sim$10--37$\mu$m high resolution spectra obtained with Spitzer/IRS.

Seasonal changes in microbial dissolved organic sulfur transformations in coastal waters [PDF]

open access: yes, 2020
The marine trace gas dimethylsulfide (DMS) is the single most important biogenic source of atmospheric sulfur, accounting for up to 80% of global biogenic sulfur emissions.

The Curious Conundrum Regarding Sulfur Abundances In Planetary Nebulae [PDF]

open access: yes, 2012
Sulfur abundances derived from optical emission line measurements and ionization correction factors in planetary nebulae are systematically lower than expected for the objects' metallicities. We have carefully considered a large range of explanations for

Conventional superconductivity at 203 kelvin at high pressures in the sulfur hydride system [PDF]

open access: yesNature, 2015
A superconductor is a material that can conduct electricity without resistance below a superconducting transition temperature, Tc. The highest Tc that has been achieved to date is in the copper oxide system: 133 kelvin at ambient pressure and 164 kelvin ...

Influence of the Sulfur Content Catalyst on the Packing Density of Carbon Nanotube Forests

open access: yesNanomaterials, 2019
For the fabrication of high-performance carbon nanotube (CNT) composites with practical applicability, the development of new methods for the controlled growth of high-aspect-ratio CNTs still constitutes a challenge.

Sulfur phase and sulfur removal in high sulfur-containing bauxite [PDF]

open access: yesTransactions of Nonferrous Metals Society of China, 2011
Abstract The sulfur phase in high sulfur-containing bauxite was studied by an X-ray diffraction analysis and a chemistry quantitative analysis. The methods for the removal of different shaped sulfur were also discussed. The results show that sulfur phases in high sulfur-containing bauxites exist in the main form of sulfide sulfur (pyrite) or sulfate ...
