2. 1. Housing Aquaporins in Nanostructured Glass

   Author : Simon Isaksson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane protein; Water; Interface; Aquaporin; Silica; Formation; Silicification;

   Abstract : Proteins are a group of biomolecules that perform versatile tasks, which in many cases are essential for life. The magnitude of their importance is perhaps expressed by the word protein itself, coined by the Swedish chemist Jöns Jacob Berzelius in the summer of 1838. READ MORE

4. 2. Spray-Dried Powders for Inhalation : Particle Formation and Formulation Concepts

   Author : Jessica Elversson; Göran Alderborn; Anna Millqvist-Fureby; Lars Hovgaard; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Spray drying; Particle formation; Density; Protein formulation; Encapsulation; Coating; Competitive adsorption; Polymer; ESCA; AFM; FTIR; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

   Abstract : Spray drying is a method with a high potential in the preparation of protein particles suitable for pulmonary delivery. However, surface induced denaturation of bio-molecules during atomization and subsequent drying can be substantial and it is therefore important to develop new formulation concept for concurrent encapsulation and stabilization of proteins during spray drying.

5. 3. Silicon device substrate and channel characteristics influenced by interface properties

   Author : Mikael Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel; attenuation; zro2; interface; traps; semi-insulating; high-k; mos; cross-talk; hfo2;

   Abstract : This thesis is divided in two parts, one dealing with the depleted Si/Si structure, which is a substrate behaving as a semi-insulating material intended for radio-frequency applications and the other concerning high-k gate dielectrics (dielectrics with high dielectric constant) as the replacement for silicon dioxide as MOS gate dielectric.High frequency applications of CMOS integrated circuits, to lower cost, achieve higher performance and richer functionality, depends partly on the possibility to decrease the substrate coupling between different parts of the circuit.

6. 4. LiMn2O4 as a Li-ion Battery Cathode. From Bulk to Electrolyte Interface

   Author : Tom Eriksson; Michael M. Thackeray; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; cathode materials; lithium manganese oxide; interface; surface layer; electrode kinetics; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : LiMn2O4 is ideal as a high-capacity Li-ion battery cathode material by virtue of its low toxicity, low cost, and the high natural abundance of Mn. Surface related reactions and bulk kinetics have been the major focus of this work. READ MORE

7. 5. Formation stability and electronic structure of surfaces and interfaces from first principles

   Author : Jochen Rohrer; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; band structure; van der Waals interaction; electronic structure; graphane; graphene; atomic structure; growth; thin film; interface; density functional theory; CVD; Alumina; nucleation;

   Abstract : This thesis deals with two closely interwoven aspects of first-principle(density functional theory) materials modeling:(1)~prediction of atomic structure & chemical composition,and (2)~prediction of electronic properties.In the first part, we focus on atomic structure (AS) and chemical composition (CC) of surface and interface systems.
