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) ...
Synthetic approaches to five-membered heterocycles containing both ring and side-chain phosphorus atoms
(1983)
A brief review of the importance and variety of symmetrical
and unsymmetrical bisphosphines is given and the possible theoretical
and synthetic value of bisphosphines in which one of the phosphorus
atoms is included in ...
Aspects of the environmental chemistry of methoxychlor
(1980)
Preliminary investigations on the Environmental Chemistry of Methoxychlor [2,2-bis (p - methoxyphenyl)-1,1,1- trichloroethane], a potential DDT replacement, have been conducted with emphasis on its degradation
by ...
Bidentate phosphine complexes of copper (I) : their syntheses and interactions with sodium tetrahydroborate and sodium cyanotrihydroborate
(1981)
Copper(l) chloride and perchlorate complexes of the
types (L~L)CuCl, (L-L)[subscript 3]Cu[subscript2]X[subscript2] (X=Cl-,C10-4), C(L-L)[subscript2]Cu]C10[subscript4] (L-L=DPPM, DPPE, trans VPP, cis VPP, DPPP, DPPB,DPPPe,DPPH) ...
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 ...
Optical determination of metal-semiconductor Schottky barriers
(1982)
The photovoltage produced by a Schottky barrier
photocell shows a strong temperature dependence if the
barrier is not too large. We have used this temperature
dependence to obtain the barrier height for several ...
Some dielectric and spectroscopic studies on hydrogen bonding
(1984)
Dielectric relaxation studies were carried out
principally on some hydroxy compounds (e.g., phenols) and
some carboxylic acids in polystyrene (PS) matrices and,
in some cases, in compressed solids (CS). The hydroxy
compounds ...
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 ...
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 ...
Some relaxation studies of molecular and intramolecular motions in glassy o-terphenyl
(1982)
In this work, the results of dielectric
studies carried out on a number of molecules of the general form y [symbol] x are presented. These molecules have been studied mainly in two forms: as solutions of glassy o-terphenyl, ...
