Fatigue craze initiation in polycarbonate: study by transmission electron microscopy
(Elsevier, 1994-08)
Fatigue craze initiation in bulk, amorphous polycarbonate (PC) is investigated by means of transmission electron microscopy. The results agree very well with small angle X-ray scattering measurements of the same set of ...
Three-dimensional solubility parameters and chemical protective clothing permeation. I. Modeling the solubility of organic solvents in Viton® golves
(Wiley Subscription Services, Inc., A Wiley Company, 1993-10-15)
A model based on the polymer solution theory of Flory and Rehner is presented for estimating the solubility of organic solvents in chemical protective clothing (CPC) polymers using three-dimensional (3-D) solubility ...
Galanin inhibits rat pancreatic amylase release via cholinergic suppression
(Elsevier, 1992)
The effects of galanin on pancreatic exocrine function were examined using rat pancreatic tissues. In anesthetized rats, galanin (40 [mu]g/kg/h) decreased amylase secretion stimulated by 2-deoxy glucose (5.8 +/- 0.1 vs. ...
Heat capacity and thermodynamic properties of deuterated ammonium hexafluorophosphate ND4PF6 from 5.8 K to 347 K
(Elsevier, 1990-10)
The heat capacity of deuterated ammonium hexafluorophosphate ND4PF6 was measured from 5.8 K to 347 K by adiabatic calorimetry. Two [lambda]-shaped anomalies were found in the curve for heat capacity against temperature. ...
The participation of coenzyme Q in free radical production and antioxidation
(Elsevier, 1990)
Published experimental data pertaining to the participation of coenzyme Q as a site of free radical formation in the mitochondrial electron transfer chain and the conditions required for free radical production have been ...
The thermochemical and thermophysical functions of solid Sr(OH)2 AND [beta]-Ba(OH)2
(Elsevier, 1990-01-30)
Low-temperature heat capacities from 5 to 350 K by adiabatic calorimetry and high-temperature enthalpy increments above 450 K by drop calorimetry of high-purity Sr(OH)2 and [beta]-Ba(OH)2 have been measured. From the ...
The microwave spectrum and structure of the neon-phosphorus trifluoride complex
(Elsevier, 1990-08-17)
Symmetric top spectra were observed for the 20Ne[middle dot]PF3 and 22Ne[middle dot]PF3 van der Waals dimers using a Fourier-transform microwave spectrometer. The center-of-mass distance between Ne and PF3 is 3.373(3) A. ...
New out-of-plane angle and bond angle internal coordinates and related potential energy functions for molecular mechanics and dynamics simulations
(John Wiley & Sons, Inc., 1999-07-30)
With currently used definitions of out-of-plane angle and bond angle internal coordinates, Cartesian derivatives have singularities, at ±Π/2 in the former case and Π in the latter. If either of these occur during molecular ...
Thermodynamics of copper sulfides IV. Heat capacity and thermodynamic properties of Cu1.90S from 5 K to 750 K, Cu1.95S from 5 K to 1000 K, Cu1.98S from 300 K to 1000 K, and Cu1.995S from 300 K to 750 K
(Elsevier, 1990-11)
The heat capacities of Cu1.90S, Cu1.95S, Cu1.98S, and Cu1.995S have been measured by adiabatic-shield calorimetry. All samples have been characterized by powder X-ray diffraction in the temperature interval studied. A ...
Thermodynamic properties of ammonium halogen stannates I. Heat capacity and thermodynamic functions of deuterated ammonium hexachlorostannate (ND4)2SnCl6 from 5.9 to 347 K
(Elsevier, 1990-02)
The heat capacity of deuterated ammonium hexachlorostannate (ND4)2SnCl6 was measured from 5.9 to 347 K by adiabatic calorimetry. The heat capacity is characterized by a [lambda]-shaped anomaly that reaches its maximum Cp,m ...
