Phase Diagram: Bonding Dynamics
2016Phonon spectrometric mapping of the O:H–O bond relaxation dynamics across the phase diagram along the following paths confirmed the reality of the O:H–O cooperativity mechanism: (i) liquid water at 300 K and ice at 80 K as a function of pressure, (ii) liquid water cooling from 350 to 80 K under the ambient pressure, (iii) mechanical freezing of the ...

Ultrafast lattice-bonding dynamics of tellurium
Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges, 2003Summary form only given. In this paper we present a study of the ultrafast bonding dynamics of tellurium in the presence of a symmetry-preserving coherent phonon. The coherent phonon modulates the band structure at THz frequencies. We measure the dielectric function, because it is closely related to the band structure, over a broad frequency range ...

Dynamic Covalent Bonds in Polymeric Materials
Angewandte Chemie International Edition, 2019AbstractDynamic covalent bonds (DCBs) have received significant attention over the past decade. These are covalent bonds that are capable of exchanging or switching between several molecules. Particular focus has recently been on utilizing these DCBs in polymeric materials.

Vibrational dynamics in hydrogen bonded systems
Journal of Molecular Liquids, 2003Abstract We report measurements performed by Fourier Transform Infrared Spectroscopy (FTIR) on trehalose aqueous solutions. The interest on this system is mainly due to its extraordinary effectiveness as bio-protector against freezing and dehydration. The main purpose of the present work is to investigate the structural properties of trehalose and to

Dynamic strength of molecularly bonded surfaces
The Journal of Chemical Physics, 2006This study reports a theoretical analysis of the forced separation of two adhesive surfaces linked via a large number of parallel noncovalent bonds. To describe the bond kinetics, we implement a three-state reaction model with kinetic rates obtained from a simple integral expression of the mean first passage time for diffusive barrier crossing in a ...

Bond Price Dynamics and Options
The Journal of Financial and Quantitative Analysis, 1983This paper provides a closed-form, preference-free means of valuing a European call option written on a default-free pure discount bond. Investors may not agree upon a theory of the term structure, but they will necessarily agree on equilibrium option values.

Bond making and bond breaking in molecular dynamics
International Journal of Quantum Chemistry, 1996The theoretical concept of a potential energy surface, so important for the accepted pictures of molecular structure and bonding, plays a key role in most current methods of molecular reaction dynamics. However, the lack of quality potential energy surfaces for anything but the smallest of systems and the great expense and difficulty in producing ...

DYNAMIC MODELS OF BOND REFUNDING*
Decision Sciences, 1975Dynamic programming models of bond refunding have been given by Weingartner [14], Kalymon [8] and Elton and Gruber [4]. This paper gives a formulation of this problem that lends itself to extensions including the term structure of interest rates, delayed‐call provisions, and “rolling over” the outstanding debt.

Return Dynamics of Distressed Bonds
The Journal of Portfolio Management, 2009This study adds to the small, but growing, body of research on active management of distressed debt. The analysis stratifies the distressed debt universe in various ways to test whether certain subgroups exhibit comparatively low risk or comparatively high returns, thereby representing superior investment opportunities.

BOND GRAPHS IN VEHICLE DYNAMICS
Vehicle System Dynamics, 1987SUMMARY In modelling dynamic vehicle systems the bond graph technique appears to be a powerful tool. The method is illustrated through applications in the development of symmetrical (vertical, pitch, longitudinal), anti-symmetrical (lateral, yaw) and combined 3-dimensional motion models of a motor vehicle.
