2. 1. Lipid-based liquid crystals as drug delivery vehicles for antimicrobial peptides

   Author : Lukas Boge; Chalmers tekniska högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hexosome; antimicrobial peptide; cubosome; proteolysis; AMP; liquid crystalline nanoparticles; glycerol monooleate; Liquid crystals;

   Abstract : The development of antimicrobial resistance is a great challenge within the health sector around the world. The demand for new efficient treatments is alarming in order to treat various bacterial infections in the near future. Antimicrobial peptides (AMPs) are a group of novel antibiotics that have gain more and more attraction the past decade. READ MORE

4. 2. Nuclear Magnetic Relaxation in Micellar Solution and Lyotropic Liquid Crystals. Tools and Applications

   Author : Ruslan Sitnikov; KTH; []
   Keywords : NMR; NMR relaxation dispersion; NMR spectrometer; low NMR frequencies; NMR duplexer; NMR preamplifier; NMR lock; surfactant systems; micellar solutions; lyotropic liquid crystals; cubic mesophase;

   Abstract : Structurally, this Thesis is divided into two parts thatdescribe (i) the hardware development for NMR relaxationstudies and (ii) its applications for studies of the surfactantsystems.The developed hardware solutions allow to expand thefrequency range covered by conventional NMR spectrometers tomake NMR experiments feasible at resonance frequencies down to100 kHz.

5. 3. Study of the flow-induced structure and anisotropy in lyotropic liquid crystals for hierarchical composites

   Author : Adrian Rodriguez Palomo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; Lyotropic liquid crystals; SAXS; Hierarchical materials.; 3D printing; Rheology; Microfluidics; Birefringence microscopy;

   Abstract : Controlling the micro and nanostructure of materials is highly beneficial in order to tailor their physical properties. Extrusion-based 3D printing is a promising tool to produce hierarchical structures with controlled architecture. READ MORE

6. 4. Devlopment and relaxation of orientation in liquid crystalline polymers : transport properties of liquid crystalline polymer blends

   Author : Göran Wiberg; KTH; []
   Keywords : ;

   Abstract : In this thesis different types of liquid crystallinepolymers have been investigated with respect to build up andrelaxation of orientation. The potential of making new barriermaterials using liquid crystalline polymer blends was alsostudied. READ MORE

7. 5. Development of Novel Diffusion NMR Methods : Preclinical Applications in Colloidal Model Systems

   Author : Stefanie Eriksson; Fysikalisk kemi; []
   Keywords : diffusion NMR; diffusion tensor; Microscopic anisotropy; q-MAS; exchange; liquid crystals; yeast cell suspensions;

   Abstract : NMR is a powerful non-invasive technique utilizing radiofrequency and gradient pulses to manipulate the spinsof atomic nuclei. In particular, diffusion NMR uses strong magnetic field gradients to label the positions of spins allowing for the measurement of translational motion of molecules in liquids. READ MORE
