1. Macro- and microscopic properties of milk proteins and k-carrageenan gels / Propriedades macro- e microscopicas de geis de proteinas do leite e k-carragena
Evaluation of acid-induced sodium caseinate (CS) gelation promoted by glucono-d- lactone (GDL) was performed at different acidification rates with several protein concentrations (2-6% w/w). The kinetics of acidification and gelation were followed from pH 6.7 to the isoelectric point of casein by evaluation of the pH and mechanical properties using uniaxial c

2. Transições de fase em polimeros liquido-cristalinos de cadeia lateral / Phase transitions in side-chain liquid-cristaline polmers
Polymeric liquid crystals are materials that combine properties of both polymers and liquid crystals. These polymers can be thought as block copolymers made of ftexible and rigid molecular blocks. As in flexible block copolymers, the macrophase separation originated from the repulsion between different blocks is frustrated by the connectivity constraint impo

3. Microphase separation of diblock copolymer with moving walls
Diblock copolymers are linear chain molecules consisting of two subchains A and B grafted covalently to each other. Below some critical temperature Tc these two blocks tend to segregate, but due to the covalent bond they can segregate at best locally to form periodic structures (microdomains). For molecules whose subchains have the same length, the equilibri

4. Phase Separation in Binary Mixtures of Bipolar and Monopolar Lipid Dispersions Revealed by 2H NMR Spectroscopy, Small Angle X-Ray Scattering, and Molecular Theory
Binary mixtures of C20BAS and POPC membranes were studied by solid-state 2H NMR spectroscopy and small angle x-ray scattering (SAXS) over a wide range of concentrations and at different temperatures. Three specifically deuterated C20BAS derivatives—[1′,1′,20′,20′-2H4]C20BAS, [2′,2′,19′,19′-2H4]C20BAS, and [10′,11′-2H2]C20BAS—combined
