1. Hydrothermal Liquefaction of Kraft Lignin - The influence of capping agents and residence time
Abstract : In the context of exploring alternatives to replace fossil resources, lignin has been acknowledged as a renewable source of various aromatic compounds that have the potential of being precursors to chemicals as well as fuel additives. Originating from lignocellulosic biomass such as wood, lignin is an amorphous polymer with a high content of aromatic units and, in order to harness these units, it must be depolymerised. READ MORE

2. LIGNIN HYDROTHERMAL LIQUEFACTION IN SUBCRITICAL WATER TO PRODUCE BIOFUEL AND CHEMICALS
Abstract : Lignin is one of the most abundant amorphous macromolecules found in nature. Along with cellulose and hemicellulose, it forms a main component of biomass, and is mainly responsible for providing strength, rigidity and resistance to degradation. From a chemistry perspective, lignin is an important source of aromatics. READ MORE

3. Hydrothermal Liquefaction of Lignin into Bio-Oil
Abstract : Lignin, one of the three main components of lignocellulosic biomass, is the second most abundant organic polymer found on Earth. Nowadays, most of the lignin (almost 99%) produced in the Kraft pulping process is used as internal fuel. READ MORE

4. Neurobiological aspects of human aging and suicide
Abstract : This thesis addresses: 1) The involvement of the monoaminergic and neuropeptidergic neurotransmitter systems in the aging process, and 2) The contribution of these systems in the etiology of an age-related mental disorder: the depressive syndrome. Because of the evidence suggesting the efficacy of the SSRI in the treatment of some age-related symptoms, a comparison study of the binding characteristics of two SSRI, i. READ MORE
