The influence of beta-FeOOH nanorods on the thermal stability of poly (methyl methacrylate)
(Polymer Degradation and Stability, 2007)
Colloidal dispersions consisting of beta-FeOOH nanorods with three different aspect ratios (4, 75 and 120) were synthesized using thermal hydrolysis of FeCl3 solutions. After surface modification with oleic acid, the ...
Influence of solvent on the structural and morphological properties of AgI particles prepared using ultrasonic spray pyrolysis
(Materials Chemistry and Physics, 2008)
Silver iodide particles were synthesized in the process of ultrasonic spray pyrolysis using aqueous solutions of thermodynamically stable silver iodide clusters as precursor. The AgI particles were collected in solvents ...
Space-charge effects in twisted quadrupoles
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2006)
This paper presents analytical and numerical solutions of space-charge effects in the beam in the twisted quadrupole. It considers the effects of space-charge forces on an elliptical beam with a uniform particle distribution. ...
Canonical approach to 2D supersymmetric WZNW model coupled to supergravity
(Modern Physics Letters A, 2002)
Starting from the known representation of the Kac-Moody algebra in terms of the coordinates and momenta, we extend it to the representation of the super Kac-Moody and super Virasoro algebras. Then we use general canonical ...
Excessive excitation of hydrogen peroxide during oscillatory chemical evolution
(Journal of Physical Chemistry. Part A: Molecules, Spectroscopy, Kinetics, Environment and General Theory, 2007)
The peculiar reaction dynamics of the Bray-Liebhafsky chemical oscillator is connected with the nonequilibrium periodic excitations of hydrogen peroxide embedded in a hydrogen-bonded water network. This was indicated by ...
Influence of non-uniformity of coal and distribution of active calcium on sulfur self-retention by ash - A case study of lignite Kolubara
(Energy and Fuels, 2002)
Self-retention Of SO2 by ash of different grades of Kolubara lignite was experimentally investigated in a laboratory furnace. The peculiarity of this type of coal is that in the open pit there are distinct layers of coal ...
Dielectric studies of molecular beta-relaxation in low density polyethylene: the influence of drawing and ionizing radiation
(Polymer, 2002)
The dielectric relaxation behavior of low density polyethylene, uniaxially oriented to different draw ratios (3, 7 and 10) and irradiated to different absorbed doses (100, 200, 300, 500 and 700 kGy) of gamma radiation was ...
Correlation for the total sulfur content in char after devolatilization
(Energy and Fuels, 2006)
The overall process of coal combustion takes place in two successive steps: devolatilization and char combustion. The fate of sulfur during the devolatilization of coal of different rank was investigated. The significance ...
Theory of photothermal effects in thermally inhomogeneous solids with constant effusivity
(Journal of Physics. D: Applied Physics, 2000)
The analysis of the thermal wave generation and propagation in thermally inhomogeneous solid with constant effusivity is presented. The developed theory is based on an exact solution of an inhomogeneous heat conduction ...
Theory of the central ion trajectory in the spiral inflector
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2000)
This paper presents the analytical and numerical theory of the central ion trajectory through the spiral inflector. Analytical expressions for the equations which describe the central ion trajectory are derived. (C) 2000 ...
