Dielectric studies of rigid and flexible molecules in various media
(1984)
This thesis investigates mainly the molecular and
intramolecular relaxation processes of some aromatic and
aliphatic molecules containing rotatable polar groups and
some analogous rigid molecules dispersed in (a) ...
Studies on the decomposition of alcohols on metal oxide catalysts
(1982)
The catalytic decomposition of 2-propanol has
been investigated by a micropulse reactor technique in the
temperature range from 461 to 547 K on nickel oxide and
alumina doped nickel oxide. Nickel oxide is active for
the ...
Synthesis and biodegradation of model compounds related to hydrocarbon-type dielectric fluids
(1981)
Uniroyal PA0-20E, an oligomer of 1-octene, is a dielectric
fluid proposed as a replacement for polychlorinated biphenyls. No
studies on its biodegradation have been reported in the literature
to date.
This thesis ...
Thermal decomposition and gasification of cellulose and wood wastes
(1980)
The thermal decomposition of jack pine bark, white birch sawdust
and cellulose has been studied by both isothermal weight-change determinations and dynamic thermogravimetry mostly in inert atmospheres up to 900°C. Gaseous ...
Dielectric studies of molecular motions in some solids
(1982)
Dielectric absorption of a number of nonpolar,
weakly polar and fairly polar molecules in the
pure solid state are studied. Measurements of these
solids using either a General Radio 1621 Precision
Capacitance Measurement ...
Studies related to the chemistry and environmental persistence of methoxychlor and its derivatives
(1983)
An Investigation of some of the chemical and biological
factors Influencing the environmental fate of methoxychlor
( 1 , 1, 1-trichloro-2,2-bis (p-methoxyphenyl) ethane) has been
conducted.
Methoxychlor is an organochlorine ...
Molecular and intramolecular relaxation processes of small molecules
(1980)
The dielectric relaxation method was used to determine
the activation parameters of some ethane derivatives and simple
amides. A General Radio 1615-A capacitance bridge was utilized to
obtain the energy barriers of the ...
Reactions of Ni (II) with sodium cyanotrihydroborate in presence of some bidentate phosphines
(1982)
Cyanotrihydroborate-transiton metal ion chemistry has been reviewed.
Photolysis of poly-acyl styrene polymers
(1989)
The following is a study of the long wave (wavelength >300 nm) photolysis
of a series of poly acyl styrenes, in particular, poly-p-acetyl-styrene (PPAS), polyp-
propionyl-styrene (PPPS), poly-o-acetyl-styrene (POAS), ...
Relaxation processes of polar molecules in some organic glasses
(1982)
Dielectric absorption studies of a variety
of polar solutes containing rotatable groups and of
some analogous rigid molecules dispersed in (i) an
atactic polystyrene matrix, (ii) glassy o-terphenyl
and polyphenyl ether ...
