2. 1. Adsorption of biopolymers and their layer-by-layer assemblies on hydrophilic surfaces

   Author : Maria Lundin; Eva Blomberg; Thomas Arnebrant; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Layer-by-layer; multilayer; adsorption; biopolymers; Chitosan; Heparin; Mucin; Albumin; Lysozyme; β-casein; SDS; QCM-D; Ellipsometri; DPI; TIRF; FRET; SFA; layer structure; solvent content; vertical diffusion; exponential growth; solid-liquid interface; deposition conditions; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : It is widely known that surfaces play an important role in numerous biological processes and technological applications. Thus, being able to modify surface properties provides an opportunity to control many phenomena occurring at interfaces. READ MORE

4. 2. Quantity and quality of soil organic matter in permafrost terrain

   Author : Gustaf Hugelius; Peter Kuhry; Philip Wookey; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbon; soil organic matter; soil organic carbon; permafrost; arctic; upscaling; peat plateau; cryoturbation; active layer; thermokarst; carbon nitrogen ratio; stable isotopes; humification; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Physical Geography;

   Abstract : High latitude terrestrial ecosystems are considered key components in the global carbon (C) cycle and hold large reservoirs of soil organic carbon (SOC). Much of this is stored as soil organic matter (SOM) in permafrost soils and peat deposits and is vulnerable to remobilization under future global warming. READ MORE

5. 3. Miniaturized localized surface plasmon resonance biosensors

   Author : Si Chen; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colloidal lithography; Surface plasmon resonance; biosensing; electron beam lithography; single molecule; hyperspectral imaging; photo functionalization;

   Abstract : Abstract Reliable and sensitive biosensors are required for fast and accurate diagnostics. Localized surface plasmon resonances (LSPRs) in noble-metal nanoparticles possess very high refractive index sensitivity close to the metal surface and therefore constitute an attractive biosensing platform.

6. 4. Synthesis and characterization of Mo-based nanolaminates

   Author : Rahele Meshkian; Johanna Rosén; Árni Sigurður Ingason; Hans Högberg; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Mn+1AXn (MAX) phases are nanolaminated compounds based on a transition metal (M), a group A element (A), and carbon or/and nitrogen (X), which exhibit a unique combination of ceramic and metallic properties. Mo-based MAX phases are among the least studied, despite indication of superconducting properties and high potential for fabrication of the grapheneanalogous 2D counterpart, Mo2C MXene. READ MORE

7. 5. Interfacial Properties of Film Forming Proteins and their Layer-by-Layer Assembly with Nanoparticles

   Author : Olga Krivosheeva; Per Claesson; Thomas Arnebrant; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein adsorption; mussel adhesive protein; Mefp-1; hydrophobins; HFBI; HFBII; adsorption kinetics; layer-by-layer; stability; cross-linking; zeta-potential; dual polarization interferometry; quartz crystal microbalances;

   Abstract :  The aim of this thesis work was to investigate the interfacial properties of film forming proteins, stability of the layers created by them, and their interactions with nanoparticles. Mussel adhesive protein (Mefp-1) and hydrophobins (HFBI and HFBII) were the three main proteins used. READ MORE
