1. Ion specific effects in polymer conformation
Kandidat-uppsats, KTH/Tillämpad fysikalisk kemiSammanfattning : It is well known that ions affect polymers in specific ways not solely based on electric charge, usually referred to as the Hoffmeister effect or ion specific effects. Poly(N-isopropylacrylamid) (PNIPAM) is a thermosensitive polymer with a LCST at 32℃. LÄS MER
2. Characterizing the pore structure of porous matrices using SEQ-NMR spectroscopy
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Characterization of the pore structure is a crucial part in themanufacturing of porous media used for purification of biologicalpharmaceuticals. This project took place at Cytiva in Uppsala and aimedat optimizing a newly developed method in pore structurecharacterization called size-exclusion quantification NMR (SEQ-NMR). LÄS MER
3. Making wood durable. A sustainable approachwith linseed oil
Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Linseed oil has been and is used for vast number of applications, such as in food and paint industry, and wood preservation. It is a good environmental choice, as it originates from renewable sources. Linseed oil is mainly a mixture of triglyceride of fatty acids, both saturated and mono- or polyunsaturated, which allows the oil to oxidize. LÄS MER
4. Dissolution and fibre spinning of cellulose from an ionic liquid
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Regenerated cellulose fibres can become a sustainable alternative to cotton and polyester in textile applications. One method of producing such is dissolution of cellulose in an ionic liquid (IL) and regeneration through air-gap spinning. LÄS MER
5. Orientation of Sticks and Spheres - Estimating Tensor Shape and Orientation Distribution using Diffusion NMR
Master-uppsats, Lunds universitet/Biofysikalisk kemiSammanfattning : The diffusion characteristics of water can be measured by using NMR methods. Specifically, the diffusion profiles in samples containing domains of water barriers are of major importance to be able to describe in applications such as diffusion tensor imaging or diffusion MRI-sequences.
