This book was released on 1993 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear magnetic resonance (NMR) spectroscopy was used in solution-state and solid-state experiments on 8 asphalt cements. Using a variety of chemical and solution-state NMR spectroscopic techniques, data were obtained about the amounts of aromatic carbon in an average molecule of asphalt sample, how the carbon is arranged in terms of size of the average aromatic system and the extent of substitution. By using solid-state NMR spectroscopic techniques, the structure of asphaltic cements was probed on a small-distance scale. Difference in molecular mobility were found among the asphalts studied. Changes in molecular mobility after laboratory oxidative aging were found to be small. The implications of these data with regard to the 'micellar model' of asphalt are discussed. The research results' potential impact on understanding asphalt cement properties is explored.

Download or read book Nuclear Magnetic Resonance Spectroscopy written by Frank A. Bovey and published by Elsevier. This book was released on 1988-11-01 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear Magnetic Resonance Spectroscopy, Second Edition focuses on two-dimensional nuclear magnetic resonance (NMR) spectroscopy, high resolution NMR of solids, water suppression, multiple quantum spectroscopy, and NMR imaging. The selection first takes a look at the fundamental principles and experimental methods. Discussions focus on the NMR phenomenon, dipolar broadening and spin-spin relaxation, nuclear electric quadrupole relaxation, saturation, magnetic shielding and chemical shift, magnetic field, transitions between the nuclear energy levels, and resolution and sensitivity considerations. The manuscript then ponders on chemical shift, coupling of nuclear spins, and nuclear relaxation and chemical rate processes. Topics include spin lattice relaxation, spin-spin relaxation, spin decoupling and associated techniques, and description and analysis of spin systems. The text examines two-dimensional NMR spectroscopy, macromolecules, and NMR of solids, including magic angle spinning, cross polarization, proton dipolar broadening, biopolymers, and chain motion in macromolecules. The selection is a valuable source of data for readers interested in nuclear magnetic resonance spectroscopy.

Download or read book Nondestructive Characterization of Materials written by Paul Höller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 894 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering structures for reliable function and safety have to be designed such that operational mechanical loads are compensated for by stresses in the components bearable by the materials used. Vhat is "bearable"? First of all it depends on the properties of the chosen materials as well as on several other parameters, e.g. temperature, corrosivity of the environment, elapsed or remaining serviceable life, unexpected deterioration of materials, whatever the source and nature of such deterioration may be: defects, loss of strength, embrittlement, wastage, etc. DEFECTS and PROPERTIES of materials currently determine loadability. Therefore in addition to nondestructive testing for defects there is also a need for nondestructive testing of properties. The third type of information to be supplied by nondestructive measurement pertains to STRESS STATES under OPERATIONAL LOADS, i.e. LOAD-INDUCED plus RESIDUAL STRESSES. Residual stresses normally cannot be calculated; they have to be measured nondestructively; well-approved elastomechanical finite element codes are available and used for calculating load-induced stresses; for redundancy and reliability, engineers, however, need procedures and instrumentation for experimental checks.
