   Kandidat-uppsats, KTH/Tillämpad fysikalisk kemi

   Författare :Lovisa Svanholm; Anna Köttö; Samuel Deuda Lundkvist; [2021]
   Nyckelord :Poly N-isopropylacrylamid ; PNIPAM; pre-transitional chain collapse; ion specific effects; Hoffmeister series; LCST; diffusion NMR; self-diffusion NMR; fractionation; kosmotropes; chaotropes; inversion recovery experiment;

   Sammanfattning : 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

3. 2. NMR detection of liquid dynamics in porous matrices

   Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemivetenskap (CHE)

   Författare :Payam Pourmand; [2012]
   Nyckelord :Porous material; Controlled Pore Glass; NMR; Diffusion NMR;

   Sammanfattning : Porous materials or a porous media can be encountered in our everyday life, both in industrial and household systems and in the nature. Generally speaking all solid and semisolid materials are porous to some degree e.g. different dense rock types, plastics etc. LÄS MER
