Some studies of vibrational relaxation using a shock tube
Thesis
Gutteridge, R. Some studies of vibrational relaxation using a shock tube. https://keele-repository.worktribe.com/output/412913

The vibrational relaxation of HCl, HBr, HI or DCl has been studied either as a pure gas or in mixtures with argon, nitrogen or carbon monoxide. Infrared radiation from the second or third vibrational levels was used to follow the relaxation process.... Read More about Some studies of vibrational relaxation using a shock tube.

Synthesis of benz- and cyclohepta-pyridines
Thesis
Jones, R. K. Synthesis of benz- and cyclohepta-pyridines. https://keele-repository.worktribe.com/output/412920

The methods of synthesis of benzocyclohepteneones are reviewed.
A sequential Claisen - Dieckmann condensation has been used to prepare di-alkyl 5,9-dihydroxy-7H-cyclohepta-[b]-and-[c]-pyridine-6,8-dicarboxylates.
These have been converted to the cy... Read More about Synthesis of benz- and cyclohepta-pyridines.

Studies of the reactions of 3H-pyrrolizines with acetylenes
Thesis
Johnson, D. Studies of the reactions of 3H-pyrrolizines with acetylenes. https://keele-repository.worktribe.com/output/412921

An attempt was made to synthesise azonia-azulenium salts by the 2+2 cycloaddition of acetylenes to 3H-pyrrolizine, and the subsequent ring expansion of the cyclobutene product.
In Part I the attempted syntheses of some new 3Hpyrrolizines are describ... Read More about Studies of the reactions of 3H-pyrrolizines with acetylenes.

Gas incorporation in sputtered and evaporated metal films
Thesis
Mitchell, I. V. Gas incorporation in sputtered and evaporated metal films. https://keele-repository.worktribe.com/output/412924

The argon and nitrogen gas concentrations in thin films have been measured for seven different metals. Sputtered and evaporated films are deposited on glass and tungsten substrates in a stainless steel ultra high vacuum system, which is designed to o...

Studies on the structure of the insect feeding inhibitor azadirachtin
Thesis
Percy, G. Studies on the structure of the insect feeding inhibitor azadirachtin. https://keele-repository.worktribe.com/output/412925

Azadirachtin C35H44O16, a locust feeding inhibitor, was first extracted from neem seeds by Butterworth in 1967. Butterworth identified two acetate esters, two carboxymethyl groups, a tiglate ester, two hydroxyl groups and a 2,3-dihydrofuran ring in t...

The optical properties of rare earth metals
Thesis
Cleyet, B. The optical properties of rare earth metals. https://keele-repository.worktribe.com/output/412934

Ellipsometric measurements at the film-substrate interface of the optical constants of five lanthanide metals, (Nd, Gd, Tb, Dy and Yb), have been made within 0.5 and 5.5eV. General agreement was found with theoretically predicted conductivity from A.... Read More about The optical properties of rare earth metals.

The cationic polymerization of ketene acetals
Thesis
Dunn, D. J. The cationic polymerization of ketene acetals. https://keele-repository.worktribe.com/output/412939

This work has been divided into two sections:
SECTION A (Chapters 1-5)
This section is concerned with the preparation and cationic polymerization of various ketene acetals CH2 :C(OR1)OR2. Four ketene acetals have been synthesized (two of which are... Read More about The cationic polymerization of ketene acetals.

Researches into the function of metal halides in cationic polymerisation
Thesis
Grattan, D. W. Researches into the function of metal halides in cationic polymerisation. https://keele-repository.worktribe.com/output/412941

The work was concerned with the study of the ionisation of aluminium halides in alkyl halides, and the role of these solutions in cationic polymerisatlons. These are problems of long standing interest which became topical through the proposal of a ne... Read More about Researches into the function of metal halides in cationic polymerisation.
