Proteomic and Isotopic Response of Desulfovibrio vulgaris to DsrC Perturbation

Frontiers in Microbiology, 2019
Dissimilatory sulfate reduction is a microbial energy metabolism that can produce sulfur isotopic fractionations over a large range in magnitude. Calibrating sulfur isotopic fractionation in laboratory experiments allows for better interpretations of ...

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

mLife, EarlyView.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...

Microporous Self‐Assembled Pd(II) Tetrahedral Cages for Rapid and Reversible Multi‐Phase Sequestration of Iodine and Methyl Iodide

Small, EarlyView.
This work reports a family of microporous, self‐assembled tetrahedral coordination cages that efficiently capture iodine, polyiodides, and methyl iodide from vapor, aqueous, and organic media. The cages display exceptional uptake capacities, rapid kinetics, and high selectivity, enabling the first dynamic vapor‐phase iodine capture by coordination ...

Titanium Detected in Liver, Kidney, Spleen, and Intestine Is Not Related to Dose, Time, or Route of Exposure to Titanium Dioxide: A Systematic Review

Environmental Toxicology, EarlyView.
ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

Box Models of Volatile Cycles over the Entire Phanerozoic [PDF]

, 2006
Three stand-alone geochemical box models have been developed to simulate globally coupled biogeochemical cycles. These models reflect the evolution of the participating biotic and abiotic constituents in marine and terrestrial environments, including the

Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

Scaffold Dependent Coordination Modes of Chelating PEP‐Type Ligands in Iron(0) Carbonyl Complexes (E = O, S)

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The reaction of iron pentacarbonyl with various chelating diphosphine ligands containing oxygen or sulfur atoms in their backbone yields complexes that exhibit noteworthy coordination behavior. Depending on the natural bite angle of the ligands and the coordination behavior of the heteroatom, preferences regarding the coordination geometry are verified

Chlorine and Bromine Isotope Fractionation of Halogenated Organic Pollutants on Gas Chromatography Columns

, 2017
Compound-specific chlorine/bromine isotope analysis (CSIA-Cl/Br) has become a useful approach for degradation pathway investigation and source appointment of halogenated organic pollutants (HOPs).
