Blind deconvolution of time-of-flight mass spectra from atom probe tomography.

Ultramicroscopy

Johnson LJ, Thuvander M, Stiller K, Odén M, Hultman L.
PMID: 23607992
Ultramicroscopy. 2013 Sep;132:60-4. doi: 10.1016/j.ultramic.2013.03.015. Epub 2013 Mar 29.

A major source of uncertainty in compositional measurements in atom probe tomography stems from the uncertainties of assigning peaks or parts of peaks in the mass spectrum to their correct identities. In particular, peak overlap is a limiting factor,...

Dislocation-pipe diffusion in nitride superlattices observed in direct atomic resolution.

Scientific reports

Garbrecht M, Saha B, Schroeder JL, Hultman L, Sands TD.
PMID: 28382949
Sci Rep. 2017 Apr 06;7:46092. doi: 10.1038/srep46092.

Device failure from diffusion short circuits in microelectronic components occurs via thermally induced migration of atoms along high-diffusivity paths: dislocations, grain boundaries, and free surfaces. Even well-annealed single-grain metallic films contain dislocation densities of about 10

Synthesis of Polymerizable Cyclodextrin Derivatives for Use in Adhesion-Promoting Monomer Formulations.

Journal of research of the National Institute of Standards and Technology

Bowen RL, Carey CM, Flynn KM, Guttman CM.
PMID: 27504209
J Res Natl Inst Stand Technol. 2009 Feb 01;114(1):1-9. doi: 10.6028/jres.114.001. Print 2009.

The synthesis of the cyclodextrin derivatives reported herein was assisted by extensive literature research together with structure-property relationships derived from three-dimensional molecular modeling. These studies led to the hypothesis that many of the 21 hydroxyl groups on beta-cyclodextrin molecules...

Two-Dimensional, Ordered, Double Transition Metals Carbides (MXenes).

ACS nano

Anasori B, Xie Y, Beidaghi M, Lu J, Hosler BC, Hultman L, Kent PR, Gogotsi Y, Barsoum MW.
PMID: 26208121
ACS Nano. 2015 Oct 27;9(10):9507-16. doi: 10.1021/acsnano.5b03591. Epub 2015 Aug 13.

The higher the chemical diversity and structural complexity of two-dimensional (2D) materials, the higher the likelihood they possess unique and useful properties. Herein, density functional theory (DFT) is used to predict the existence of two new families of 2D...

Synthesis and Characterization of an Alumina Forming Nanolaminated Boride: MoAlB.

Scientific reports

Kota S, Zapata-Solvas E, Ly A, Lu J, Elkassabany O, Huon A, Lee WE, Hultman L, May SJ, Barsoum MW.
PMID: 27220751
Sci Rep. 2016 May 25;6:26475. doi: 10.1038/srep26475.

The 'MAlB' phases are nanolaminated, ternary transition metal borides that consist of a transition metal boride sublattice interleaved by monolayers or bilayers of pure aluminum. However, their synthesis and properties remain largely unexplored. Herein, we synthesized dense, predominantly single-phase...

Two-dimensional Mo.

Nature communications

Tao Q, Dahlqvist M, Lu J, Kota S, Meshkian R, Halim J, Palisaitis J, Hultman L, Barsoum MW, Persson POÅ, Rosen J.
PMID: 28440271
Nat Commun. 2017 Apr 25;8:14949. doi: 10.1038/ncomms14949.

The exploration of two-dimensional solids is an active area of materials discovery. Research in this area has given us structures spanning graphene to dichalcogenides, and more recently 2D transition metal carbides (MXenes). One of the challenges now is to...

Metal powder substrate-assisted laser desorption/ionization mass spectrometry for polyethylene analysis.

Analytical chemistry

Yalcin T, Wallace WE, Guttman CM, Li L.
PMID: 12349979
Anal Chem. 2002 Sep 15;74(18):4750-6. doi: 10.1021/ac0256641.

Polyethylene is one of the most important industrial polymers and is also one of the most challenging polymers to be characterized by mass spectrometry. We have developed a substrate-assisted laser desorption/ionization (LDI) mass spectrometric method for polyethylene analysis. In...

An operator-independent approach to mass spectral peak identification and integration.
