1. Cellulose processing in ionic liquid based solvents
Abstract : As the most abundant polymer in nature, cellulose has an undisputed role among the raw materials to be used in a sustainable future. From its native form, in wood or straw, cellulose can be processed into products such as paper and board. READ MORE

2. Coagulation of Cellulose: from Ionic-Liquid Solution to Cellulose Nanostructure
Abstract : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. READ MORE

3. Sustained and triggered release by microencapsulation
Abstract : Uncontrolled growth of microorganisms is problematic in areas ranging from wound care to aquaculture and ship hulls. In chronic and hard-to-heal wounds, a bacterial biofilm can impair wound healing. READ MORE

4. Drying of Multicomponent Liquid Films
Abstract : The convective drying of thin layers of multicomponentliquid mixtures into an inert gas, and the influence ofdifferent process controlling mechanisms on drying selectivityis studied. Drying experiments under gas-phase-controlledconditions are performed by low intensity evaporation, fromfree liquid surfaces, of ternary mixtures without non-volatilesolutes. READ MORE

5. Quantum and quantum-classical calculations of core-ionized molecules in varied environments
Abstract : Computational quantum chemistry methods have been applied in two particular cases: to provide insight to photoionization induced fragmentation of HgBr2 and HgCl2 molecules, and to study core-electron binding energies and chemical shifts of molecules in liquid, surface adsorbed and polymeric environments in the framework of quantum mechanics/molecular mechanics (QM/MM). In the photodissociation studies the computational work is based on the relativistic Dirac equation as the systems present strong spin-orbit interaction affecting the fragmentation processes.
