Laser Ablation Molecular Isotopic Spectrometry
Richard E. Russo,Alexander A. Bol'shakov,Xianglei Mao,Christopher P. McKay,Dale L. Perry,Osman Sorkhabi +5 more
TL;DR: In this article, a new method of performing optical isotopic analysis of condensed samples in ambient air and at ambient pressure has been developed: Laser Ablation Molecular Isotopic Spectrometry (LAMIS).
Journal ArticleDOI
Laser Ablation Molecular Isotopic Spectrometry: Parameter influence on boron isotope measurements
TL;DR: In this paper, the boron isotope abundance can be quantitatively determined using LAMIS and how atomic, ionic, and molecular optical emission develops in a plasma emanating from laser ablation of solid samples with various BORON isotopic composition.
Journal ArticleDOI
Laser Ablation Molecular Isotopic Spectrometry: Strontium and its isotopes
Xianglei Mao,Alexander A. Bol'shakov,Inhee Choi,Christopher P. McKay,Dale L. Perry,Osman Sorkhabi,Richard E. Russo +6 more
TL;DR: The LAMIS detection method is described in this paper for strontium isotopes from samples of various chemical and isotopic compositions, and the results demonstrate spectrally resolved measure-ments of the three individual 86 Sr, 87 Sr, and 88 Sr isotopes that are quantified using multivariate calibration of spectra.
Journal ArticleDOI
Laser ablation molecular isotopic spectrometry (LAMIS): current state of the art
TL;DR: In this paper, a femtosecond LAMIS (F2-LAMIS) was proposed, which can be used for semi-quantitative isotopic analysis at distances up to 7.8 m.
Journal ArticleDOI
Impact of low-temperature plasmas on Deinococcus radiodurans and biomolecules.
Rakesh Mogul,Alexander A. Bol'shakov,Suzanne L. Chan,Ramsey M. Stevens,Bishun N. Khare,Meyya Meyyappan,Jonathan D. Trent +6 more
TL;DR: In vitro experiments show that O2 plasmas induce DNA strand scissions and cross‐linking as well as reduction of enzyme activity, and the observed degradation and removal of biomolecules was power‐dependent.
