NMR studies of lignin models, derivatives and bleaching effluents
(1995)
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 ...
Structure and mobility of lignin in relation to pulp washing and bleaching
(1997)
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 ...
Lignin modification to produce hydrophobic products
(2017)
Kraft lignin is not widely utilized for industrial applications. In this MSc work, kraft lignin was modified by grafting hydrophobic groups to produce hydrophobic materials. The main objective was to study the grafting of ...
Synthesis and electrochemical study of Ptlr and PtRu nanomaterials
(2015)
The rapidly growing need for clean energy on a global scale has led to the emergence of
new fields of scientific research to facilitate the discovery and development of novel energy sources, such as fuel cells, which ...
Hydrolysis of silicone polymers in aqueous systems
(2001)
Silicon-29 and 'H NMR spectroscopy were used to investigate the hydrolysis
of methyl silicones in a variety of aqueous environments. Dilute acid, dilute base and
one or more of the dissolved constituents of blood plasma ...
Reactivity study of the palladium cross-coupling synthesis of enediynes
(1999)
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. ...
The development of molecular probes for the in vitro and in vivo study of glucocerebrosidase
(2017)
Parkinson’s Disease (PD) is one of the most common neurodegenerative diseases in the world. Despite its prevalence, the disease is difficult to diagnose early with the vast majority of individuals already having significant ...
Reactivity and mechanistic study of the Sonogashira coupling and Grignard-Sonogashira coupling reactions
(2002)
The interest in studying enediyne systems was stimulated by the discovery of anti-cancer
agents containing enediyne functionalities, such as esperamicin and dynemicin. These
compounds have potential for use as anti-tumour ...
Speciation of aqueous hypercoordinated organosilicate complexes / by Jiali Wen.
(2007, c 20)
Aqueous silicon chemistry plays a major and as yet unappreciated role in many fields of science. Emerging technologies such as the fabrication of biomimetic ceramics require a thorough understanding of all factors affecting ...
