Abstract: Abstract We describe a method to estimate background noise in atom probe tomography (APT) mass spectra and to use this information to enhance both background correction and quantification. Our approach is mathematically general in form… read more here.

Abstract: Historic disagreement regarding the prevalence and abundance of BMAA may be due in part to false-negative results arising from deuterated internal standards and the derivatization conditions used in prior studies. read more here.
