Recent Advances in Quantitative Synthetic-Polymer Mass Spectrometry at NIST

January 1, 2004
Author(s)
William E. Wallace, Charles M. Guttman
Commensurate with NIST s mission to advance the state of quantitative measurement science we have worked to develop a method to determine absolute molecular mass distribution of synthetic polymers by mass spectrometry. Work has centered on using matrix

Residual stress determination by diffraction: Modeling and applications

January 1, 2004
Author(s)
Davor Balzar, N C. Popa
Residual stress plays an important role in shaping Iilaterials properties. We present both the method to determine texture-weighted strain orientation distribution function for arbitrary crystal and sample symmetries and an example of the determination of

Resistance Changes Similar to Ballistic Magnetoresistance in Electrodeposited Nanocontacts

January 1, 2004
Author(s)
J Mallett, Erik B. Svedberg, H Ettedgui, Thomas P. Moffat, Alexander J. Shapiro, P J. Chen, L Gan
We have devloped an electrochemical system to allow the resistance of two metal microelectrodes grown to contact to be established and maintained automatically. A thin-film geometry was used for the microelectrodes to suppress the magnetoresistive artifact

Rotational Spectra, Conformational Structures and Dipole Moments of 2-(Ethylthio) Ethanol by Jet-Cooled FTMW and Ab Initio Calculations

January 1, 2004
Author(s)
R D. Suenram, David F. Plusquellic, Francis J. Lovas, A H. Walker, Q Liu, L H. Xu, J O. Jensen, A C. Samuels
The rotational spectra of three low-energy conformers of 2-(ethylthio)ethanol also known as ethyl 2-hydroxyethylsulfide or hydroxyethylethyl sulfide (HOEES), together with the monosubstituted C and 34S isotopic forms of the two lowest energy conformers
