Sulfur isotope analysis of aerosol particles by NanoSIMS

, 2007
A new method to measure the sulfur isotopic composition of individual aerosol particles by NanoSIMS has been developed and tested on several standards such as barite (BaSO4), anhydrite (CaSO4), gypsum (CaSO4·2H2O), mascagnite ((NH4)2SO4), epsomite (MgSO4·7H2O), magnesium sulfate (MgSO4·xH2O), thenardite (Na2SO4), boetite (K2SO4) and cysteine (an amino ...

Carbon assimilation and accumulation of cyanophycin during the development of dormant cells (akinetes) in the cyanobacterium Aphanizomenon ovalisporum

Frontiers in Microbiology, 2015
Akinetes are spore-like non-motile cells that differentiate from vegetative cells of filamentous cyanobacteria from the order Nostocales. They play a key role in the survival and distribution of these species and contribute to their perennial blooms ...

A NanoSIMS Investigation on Timescales Recorded in Volcanic Quartz From the Silicic Chon Aike Province (Patagonia)

Frontiers in Earth Science, 2018
Textural and chemical differences in coeval rhyolitic effusive and explosive eruptions are commonly observed, and numerical models predict different timescales for the eruption of crystal-rich mushes versus crystal-poor magmas. We compare quartz zonation

Intracellular isotope localization in Ammonia sp. (Foraminifera) of oxygen-depleted environments: results of nitrate and sulfate labeling experiments

Frontiers in Microbiology, 2016
Some benthic foraminiferal species are reportedly capable of nitrate storage and denitrification, however, little is known about nitrate incorporation and subsequent utilization of nitrate within their cell.

Accumulation and distribution of cadmium at organic-mineral micro-interfaces across soil aggregates

Ecotoxicology and Environmental Safety
Soil amendments are crucial in regulating cadmium (Cd) distribution as aggregates of varying sizes have different capacities to retain soil Cd. Directly observing the Cd distribution within aggregates and understanding their interactions with minerals ...
