    Abstract : During the 1990s, Latin America went through important structural transformations. The continent experienced a profound alteration in the relations between the state, society, market and natural environment. READ MORE

  4. 12. Functional Polymer Electrolytes for Multidimensional All-Solid-State Lithium Batteries

    Author : Bing Sun; Daniel Brandell; Kristina Edström; Michel Armand; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer electrolyte; Li-battery; 3D-microbattery; Functionalization; Polyether; Polycarbonate; Copolymer; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Pressing demands for high power and high energy densities in novel electrical energy storage units have caused reconsiderations regarding both the choice of battery chemistry and design. Practical concerns originating in the conventional use of flammable liquid electrolytes have renewed the interests of using solvent-free polymer electrolytes (SPEs) as solid ionic conductors for safer batteries.

  5. 13. Structural studies and design of Di-iron carboxylate proteins

    Author : Martin Andersson; Martin Bollinger Jr; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Abstract : Di-iron carboxylate proteins perform a wide range of chemical reactions in the cell. These reactions often involve activation of dioxygen to generate highly oxidative species that can be used in catalysis. One member of the di-iron carboxylate family is the enzyme ribonucleotide reductase (RNR). READ MORE

    Abstract : Continuous scaling of transistor dimensions has been in the heart of semiconductorindustry for many years. Recently the scaling has been enabled by various performance boosters which resulted in increased processing complexity and cost, forcing the chip manufacturers to look for some alternative solutions.

  7. 15. Preparation of Pharmaceutical Powders using Supercritical Fluid Technology : Pharmaceutical Applications and Physicochemical Characterisation of Powders

    Author : Sitaram Velaga; Johan Carlfors; Kristiina Järvinen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Supercritical fluid; Gas Anti-Solvent; SEDS; Crystallisation; Particle design; Polymorphs; Dry powder inhalation; Solid-state behaviour; Therapeutic proteins; Precipitation; Stability; Recombinant human growth hormone hGH ; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Abstract : The main aim of the thesis was to explore the potential of supercritical fluid (SF) techniques in the field of drug delivery. In particular, the relatively recently developed solution-enhanced dispersion by supercritical fluids (SEDS) technology has been employed in the preparation of particles/powders. READ MORE
