Investigating reversed liquid crystalline mesophases

Investigating reversed liquid crystalline mesophases

Reversed liquid crystalline mesophases, such as the reversed bicontinuous cubic, reversed hexagonal or reversed micellar cubic phase, are nowadays widely studied due to their potential applications in, for instance, the controlled delivery of functional molecules. In order to design the adequate mesophase delivery system for a specific application, the crystallographic structure of the phase ha...

Identification of Lyotropic Liquid Crystalline Mesophases

A facile synthetic route to novel thermotropic liquid crystalline polymers and characterization of their mesophases

A novel method for the synthesis of a new class of thermotropic liquid crystalline polymers has been developed: it proceeds via a polyaddition reaction involving diepoxy-containing mesogene groups and a monoamine (aniline). The reaction between the epoxy ring and the primary amine produces an intermediate containing a secondary amine which undergoes further reaction with an epoxy ring of anothe...

Computer simulation of liquid crystal mesophases

Il nostro gruppo di ricerca ha particolare esperienza nel campo delle simulazioni al calcolatore di sistemi anisotropi e cristalli liquidi. In questo contesto riassumiamo due recenti contributi, ottenuti utilizzando anche le infrastrutture del Cineca, nei due settori complementari delle simulazioni atomistiche e a livello molecolare. Our research group specializes in the subject of computer sim...

Galactosyl headgroup interactions control the molecular packing of wheat lipids in Langmuir films and in hydrated liquid-crystalline mesophases.

The behavior of the two major galactolipids of wheat endosperm, mono- (MGDG) and di-galactosyldiacylglycerol (DGDG) was studied in aqueous dispersion and at the air/liquid interface. The acyl chains of the pure galactolipids and their binary equimolar mixture are in the fluid or liquid expanded phase. SAXS measurements on liquid-crystalline mesophases associated with the electron density recons...
