Reversibility of Thermal Transitions in Dilute Dioctadecyl-Dimethyl-Ammonium Bromide Vesicles

Dioctadecyl-dimethyl-ammonium bromide (DODAB) vesicles can be characterized by their differential scanning calorimetry (DSC) thermograms comprised of two endotherms at T (s) a parts per thousand 36 A degrees C and T (m) a parts per thousand 45 A degrees C in the heating, ascribed respectively to the subgel-to-gel and gel-to-liquid crystalline transitions, and two exotherms at T'(m) a parts per thousand 40 A degrees C and T'(s) a parts per thousand 16 A degrees C in the cooling, ascribed respectively to the liquid crystalline-to-gel and gel-to-subgel transitions. It has been reported but not proved that the T (m)-transitions, the T'(m)-transitions, the T (s)-transitions, and the T'(s)-transitions are reverse to each other, displaying hystheresis Delta T (m) a parts per thousand 5 A degrees C and Delta T (s) a parts per thousand 20-25 A degrees C, respectively. By investigating the effects of the initial scanning temperature (T (i)) on the transition enthalpies (Delta H (m), Delta H (s), Delta H'(m) and Delta H'(s)), we have seen that these transitions are the reverse to each other and display different kinetics.

Removal of dyes by lignocellulose adsorbents originating from biodiesel production

In this study, use was made of tucumã cake, in natura (TCN) and thermally treated (TCT), as potential alternative adsorbents for the adsorption of cationic and anionic dyes. The effects of the parameters: contact time, adsorbent: adsorbate mass ratio, and initial concentration of dye were analyzed. The adsorption isotherms were established from optimized adsorption parameters. The best conditions for adsorption were: equilibrium time of 7 h, concentration of 25 mg L 1 and ratio of 1:200 for the methylene blue dye; and pH 6.5, concentration of 25 mg L 1 and ratio of 1:200 for the congo red dye. The adsorption process was best represented by the Dubinin–Radushkevich and Sips isotherms. The kinetics of adsorption of the dyes were best described by the pseudo-second-order kinetic and Elovich models. TCT showed the best maximum adsorption capacity (Qm) for the methylene blue dye (63.92 mg g 1 ).
