2. 1. Effects of surfactant adjuvants on plant leaf cuticle barrier properties

   Author : Anton Fagerström; Malmö högskola; []
   Keywords : Adjuvant; Surfacant; Cuticle; Tebuconazole; Diffusion; Clivia miniata Regel leaf; Model wax; Phase diagram; Hydration; Eutectic melting; Crystalline domains; Softening; Wax film; Quartz Crystal Microbalance with dissipation QCM-D ; Differential Scanning Calorimetry DSC ; Small- and Wide-angle X-ray Diffraction SWAXD ;

   Abstract : I avhandlingen undersöks växelverkan mellan det yttersta lagret på växters blad (cutikeln), aktiva substanser, och ämnen som tillsätts för att öka bekämpningsmedlens effekt, i detta fall vissa former av tensider. Barriären som hindrar upptag av främmande ämnen i växten sitter i cutikeln. READ MORE

4. 2. Ternary Block Copolymer Systems - Phase Behaviour and Phase Structure

   Author : Birgitta Svensson; Fysikalisk kemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; lyotropic; thermotropic; SANS; SAXS; scattering; semicrystalline; reverse micelle; micellar solution; liquid crystalline; phase diagram; phase behaviour; block copolymer; pluronic; poly ethylene oxide ; poly propylene oxide ; quantum chemistry; Teoretisk kemi; kvantkemi;

   Abstract : Ternary isothermal (25°C) polyoxyalkylene triblock block copolymer ((EO)x(PO)y(EO)x where x is the number of ethylene oxide, EO, segments and y is the number of propylene oxide, PO, segments) systems with water and p-xylene as selective solvents for the PEO and PPO blocks, respectively, were chosen as study systems in this thesis as these ternary systems are good model systems for the self-assembly of block copolymers. The phase behaviour has been studied at varied block copolymer molecular weight and relative PEO/PPO block ratio. READ MORE

5. 3. From dusk till dawn : three essays on organizational closedowns

   Author : Magnus Hansson; Rune Wigblad; Örebro universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business Studies; Företagsekonomi;

   Abstract : This thesis present three essays on organizational closedowns, where productivity effects under uncertainty and threat on the single-firm level is in focus. On a broad level, this thesis aims to develop better explanations of the process of organizational closedowns. READ MORE

6. 4. Thermodynamic modelling and assessment of some alumino-silicate systems

   Author : Huahai Mao; Bo Sundman; Gunnar Eriksson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermodynamic modelling; thermodynamic assessment; alumino-silicate system; slag; oxide system; CALPHAD; phase diagram; phase equilibrium; Thermo-Calc; compound energy formalism; ionic two sub-lattice liquid model; AlO2-1 species; Al2O3; CaO; MgO; SiO2; Y2O3; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : Alumino-silicate systems are of great interest for materials scientists and geochemists. Thermodynamic knowledge of these systems is useful in steel and ceramic industries, and for understanding geochemical processes. A popular and efficient approach used to obtain a self-consistent thermodynamic dataset is called CALPHAD. READ MORE

7. 5. Characterization of crystalline materials by rotation electron diffraction : Phase identification and structure determination

   Author : Yifeng Yun; Xiaodong Zou; Christian W. Lehmann; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron microscopy; phase identification; rotation electron diffraction; structure determination; three-dimensional electron diffraction; Inorganic Chemistry; oorganisk kemi;

   Abstract : Electron crystallography is powerful for determination of complex structures. The newly-developed 3D electron diffraction (ED) methods make structure determination from nano- and micron-sized crystals much easier than using other methods, for example X-ray diffraction. READ MORE
