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 ...

Multimodal Imaging of Chemically Fixed Cells in Preparation for NanoSIMS

, 2016
In this work, we have employed time-of-flight secondary ion mass spectrometry (ToF-SIMS) to image chemically fixed adrenal cells prepared for transmission electron microscopy (TEM) and subsequent high-spatial-resolution NanoSIMS imaging.

Chemical imaging of biological materials by NanoSIMS

, 2004
The NanoSIMS 50 represents the state -of-the-art for in situ microanalysis for secondary ion mass spectrometry (SIMS), combining unprecedented spatial resolution (as good as 50 nm) with ultra-high sensitivity (MDL of 200 atoms). The NanoSIMS incorporates

Correlated TEM-NanoSIMS investigation of foraminiferal metabolism [PDF]

, 2017
Foraminifera are ubiquitous eukaryotic protists inhabiting all types of marine environments. The chemical and isotopic compositions of their carbonate tests are commonly used as proxies for paleo-environmental conditions.

Chemical imaging with NanoSIMS: A window into deep-Earth geochemistry

, 2015
We use a combination of nanometer-resolution secondary ion mass spectrometry (NanoSIMS) and analytical transmission electron microscopy (ATEM) for chemical imaging of material transformed in a laser-heated diamond anvil cell (LH-DAC), in the pressure ...
