Poly(p-methoxyacrylophenone) (PMAP), poly{3,4-dimethoxyacrylophenone) (P34DMAP) and poly(3,5-dimethoxyacrylophenone) (P35DMAP) were exposed in the form of dilute solutions and thin films to long-wave UV radiation (see ...

A photochromic fulgide, coimnonly known as Aberchrome 540, is amber in its ring-opened E (see document) dimethyl -3- furylethylidene) (isopropylidene) succinic anhydride] and z (see document) furylethylidene) (isopropylidene) ...

Silicon-29 nuclear magnetic resonance (NMR) spectroscopy has been used to investigate the equilibrium distribution and kinetics of silicate oligomers in aqueous tetraalkylammonium silicate solutions. Certain tetraalkyl ...

NMR problems related to assignment techniques and relaxation restrict the use of NMR in the structural analysis of lignin. These problems have been addressed in three practical studies in this thesis involving a lignin ...

The roles of molecular size and structure were investigated in relation to the extent of peroxide bleaching and lignin adsorption on pulp. Structural analysis of components from effluents generated by peroxide bleaching ...

A reactivity study looking at various aspects of the palladium catalyzed (Sonogashira) reaction for die synthesis of enediynes was performed. Alkynes were coupled to 1,2- dichloro-, 1,2-dibromo- and 1,2-diiodobenzene. ...

Triclopyr (3,5,6-trichloro-2-pyridinyloxyacetic acid) was investigated for biodegradation using Arthrobacter and Pseudomonas sp. bacteria. No evidence of the proposed major metabolite, 3,5,6-trichloro-2-pyridinol was found ...
