Small Molecule Elimination from Group IVB (Ti, Zr, Hf) Amido Complexes

Small Molecule Elimination from Group IVB (Ti, Zr, Hf) Amido Complexes

Date: May 1993
Creator: Cundari, Thomas R., 1964- & Gordon, Mark S.
Description: This article discusses small molecule elimination from group IVB (Ti, Zr, Hf) amido complexes. An ab initio quantum chemical analysis of HX (X = H, CH₃, Cl, NH₂, SiH₃) elimination by group IVB (Ti, Zr, Hf) amidos (H₂(X)M - NH₂ → H₂M = NH + HX), of interest in the context of CVD precursor design, is reported.

Simultaneous measurement of the average ion-induced electron emission yield and the mean charge for isotachic ions in carbon foils

Simultaneous measurement of the average ion-induced electron emission yield and the mean charge for isotachic ions in carbon foils

Date: February 1997
Creator: Arrale, A. M.; Zhao, Z. Y.; Kirchhoff, J. F.; Weathers, Duncan L.; McDaniel, Floyd Del. (Floyd Delbert), 1942- & Matteson, Samuel E.
Description: This article discusses simultaneous measurement of the average ion-induced electron emission yield and the mean charge for isotachic ions in carbon foils. Knowledge of the incident ion's atomic number (Z₁) dependence of ion-induced electron emission yields can be the basis for a general understanding of ion-atom interaction phenomena and, in particular, for the design of Z₁-sensitive detectors that could be useful, for example, in the separation of isobars in accelerator mass spectrometry.

Dynamical approach to Lévy processes

Dynamical approach to Lévy processes

Date: November 1996
Creator: Allegrini, Paolo; Grigolini, Paolo & West, Bruce J.
Description: This article discusses a dynamical approach to Lévy processes, which makes it possible to derive all statistical properties of the diffusion process from the correlation function of the dichotomous fluctuating variable Φy(t).

Fractional Brownian motion as a nonstationary process: An alternative paradigm for DNA sequences

Fractional Brownian motion as a nonstationary process: An alternative paradigm for DNA sequences

Date: April 1998
Creator: Allegrini, Paolo; Buiatti, Marco, 1972-; Grigolini, Paolo & West, Bruce J.
Description: This article discusses fractional Brownian motion as a nonstationary process. The model adopted is compatible with the known biological and physical constraints, namely, it is shown to be consistent with the information of current biological literature on folding as well as with the statistical analyses of DNA sequences.

Toxicological Case Study of Dallas' Central Wastewater Treatment Plant Effluent and Ambient Trinity River Samples: 1989, 1990, 1991

Toxicological Case Study of Dallas' Central Wastewater Treatment Plant Effluent and Ambient Trinity River Samples: 1989, 1990, 1991

Date: [1991]
Creator: University of North Texas. Institute of Applied Sciences.
Description: "This study was implemented voluntarily by personnel at Dallas Water Utilities in response to concerns that the Dallas Central Wastewater Treatment Plant was adversely affecting downstream water quality." The treatment plant was studied to determine whether it was "discharging toxic materials in toxic amounts to the Trinity River" (p. 1).

High-Valent Transition-Metal Alkylidene Complexes: Effect of Ligand and Substituent Modification

High-Valent Transition-Metal Alkylidene Complexes: Effect of Ligand and Substituent Modification

Date: 1992
Creator: Cundari, Thomas R., 1964- & Gordon, Mark S.
Description: This article discusses the effects of ligand and substituent modification on the metal-carbon double bond. The main conclusion drawn from this work is that the intrinsic nature of the metal-carbon double bond can typically be changed only within certain limits by modification of the electronegativity of the ligands (L) and substituents (Z).
