A new application of time-of-flight secondary ion mass spectrometry can generate maps showing how tumors signal to their microenvironments in pancreatic cancer mouse models. Cancer researchers ...

Since the initial discovery of what has become a rapidly growing family of two-dimensional layered materials — called MXenes — in 2011, Drexel University researchers have made steady progress in ...

Secondary ion mass spectrometry (SIMS) has developed over the years into a powerful analytical tool for elemental analysis. Over the past 40 years these techniques have been utilized to make molecular ...

Secondary ion mass spectrometry, otherwise known as SIMS, is a well-established analytical technique for determining the elemental composition of a sample through ion bombardment and sputtering ...

David J Scurr and Matthew Piggott describe how time-of-flight secondary ion mass spectrometry is helping scientists in a variety of industries to understand problems related to materials science ...

SIMS imaging of lithium-ion migration within a solid electrolyte specimen. Grain boundaries resistant to ionic diffusion have created an uneven 6 Li distribution. Quantitative analysis found that ...

Cancer researchers struggle to identify tumor cells that are interspersed within nonmalignant tissues because tumor cells exploit the tissue environment and monopolize available resources to continue ...
