Incorporation of Stereo, Regio and Comonomer Defects Into the Crystalline Regions of Isotactic Polypropylene: Results From NMR, Molecular Dynamics and Chemical Shift Calculations

October 16, 2008
Author(s)
David L. VanderHart, Marc R. Nyden, R G. Alamo, L Mandelkern
We have shown that under conditions of crystallization during cooling at 1C/min, substantial amounts of 'defects' of the types a) stereo-mrrm, b) regio-2,1-erythro, c) ethylene-comonomer and d) butylene- comonomer can be found in the crystalline regions

Structural Design for Disaster Resilience

October 28, 2013
Author(s)
Fahim H. Sadek, Joseph Main, John L. Gross, Therese P. McAllister
This paper presents a brief overview of research at the National Institute of Standards and Technology (NIST) on disaster resilience of buildings, infrastructure, and communities, including component programs and projects. NIST's efforts aim at developing

Calculation of the Electron Self Energy for Low Nuclear Charge

January 1, 1999
Author(s)
U Jentschura, Peter J. Mohr, G Soff
We present a nonperturbative numerical evaluation of the one-photon electron self-energy for hydrogen like ions with low nuclear charge numbers Z = 1 to 5. Our calculation for 1S state has a numerical uncertainty of 0.8 Hz for hydrogen and 13 Hz for singly

Methodology for Obtaining and Using Toxic Potency Data for Fire Hazard Analysis

January 1, 1998
