Carbon isotope fractionation and depletion in TMC1

, 2012
12C/13C isotopologue abundance anomalies have long been predicted for gas-phase chemistry in molecules other than CO and have recently been observed in the Taurus molecular cloud in several species hosting more than one carbon atom, i.e.

Nanomolar-scale sulfate sulfur isotope analysis using a combined ion chromatography–barite precipitation and nano-EA/IRMS

Progress in Earth and Planetary Science
We report a newly developed method for analyzing the sulfur isotope ratio (34S/32S) of trace amounts of sulfate. This method consists of two steps: 1) isolation of sulfate via anion chromatography with fraction collection (IC-FC), and 2) precipitation of

SULFUR ISOTOPIC COMPOSITION OF SULFIDES FROM THE DESTRUCTION PRODUCTS OF PALEOSMOKER FROM THE YUBILEYNOE VHMS DEPOSIT (SOUTHERN URALS) [PDF]

Минералогия, 2015
Variations in sulfur composition of sulfides from fragments of the paleosmoker chimneys, sulfide turbidites, and products of their seafloor alteration are determined.

Formation of Large Native Sulfur Deposits Does Not Require Molecular Oxygen

Frontiers in Microbiology, 2019
Large native (i.e., elemental) sulfur deposits can be part of caprock assemblages found on top of or in lateral position to salt diapirs and as stratabound mineralization in gypsum and anhydrite lithologies. Native sulfur is formed when hydrocarbons come

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Versatile nitrate-respiring heterotrophs are previously concealed contributors to sulfur cycle

Nature Communications
Heterotrophic denitrifiers play crucial roles in global carbon and nitrogen cycling. However, their inability to oxidize sulfide renders them vulnerable to this toxic molecule, which inhibits the key enzymatic reaction responsible for reducing nitrous ...

Unlocking fruit dimensions: Quantification of functional traits driving plant–frugivore interactions

Applications in Plant Sciences, EarlyView.
Abstract Fleshy fruits attract animals to ingest fruit, swallow the seeds, and release them in the landscape, thus facilitating seed dispersal and plant regeneration. Attraction of animal dispersers is achieved via attractants such as color or scent, and rewards like sugars, lipids, and micronutrients.
