Journal ArticleDOI
Calorimetric study of octylcyanobiphenyl liquid crystal confined to a controlled-pore glass.
TL;DR: The heat-capacity response at the weakly first order I-N and continuous N-SmA phase transitions gradually approaches the tricritical-like and three-dimensional XY behavior, respectively.
Journal ArticleDOI
Quantitative evaluation of polymer concentration profile during swelling of hydrophilic matrix tablets using 1H NMR and MRI methods.
TL;DR: The aim was to determine the thickness of the swollen gel layer of matrix tablets and to develop a method for calculating the polymer concentration profile across the gel layer, which could be used as a general method for calculate polymer concentration profiles on other similar polymeric systems.
Journal ArticleDOI
Investigation of the state and dynamics of water in hydrogels of cellulose ethers by1H NMR spectroscopy
TL;DR: The aim of this work was to study the effect of the type of substituent of the cellulose ethers and the molecular mass on the state and dynamics of water in the respective hydrogels to specify the quantity of adsorbed water on the polymers or to calculate the average number of water molecules bound to a polymer repeating unit (PRU).
Journal ArticleDOI
Surface-induced order and diffusion in 5CB liquid crystal confined to porous glass
M. Vilfan,Tomaž Apih,A. G regorovič,Boštjan Zalar,Gojmir Lahajnar,Slobodan Žumer,Slobodan Žumer,Gerald Hinze,Roland Böhmer,G. Althoff +9 more
TL;DR: The results show that an arrangement of molecules parallel to the wall is induced by local molecular interactions between the liquid crystal and solid, resulting in a weak and temperature independent surface order parameter, S(0) approximately 0.02 +/- 0.01.
Journal ArticleDOI
Liquid crystal 8CB in random porous glass : NMR relaxometry study of molecular diffusion and director fluctuations
TL;DR: It is pointed out that in strongly confined liquid crystals the proton NMR relaxometry does not provide the evidence of director fluctuations correlated over micrometer distances as was suggested earlier, and the local translational diffusion of molecules within the cavities is found about as fast as in bulk.
